-SurpriseBot- Welcome - Net Surprise IRC - thud.net channel #netsurprise
*** TD-atvet is now known as TDavid
<TDavid> furball!
<FurBall> TD, did you get your shots yet?
<FurBall> :)
<FurBall> Hey TDavid!
<TDavid> hehe
<FurBall> I made it this time.  LOL
<TDavid> right on, thanks for coming :)
<TDavid> we're talking form input and loops today
<FurBall> NP.  :)  Glad I could make it this time. :)
*** CrEaToR has joined #netsurprise
<TDavid> i think the advanced lesson this week has brought up some interesting conversation about functions and when and when not to use them
<FurBall> Ahh... yeah, I saw the first post in the advanced lesson.  Gotta stop back and do some more reading. 
<FurBall> (And post my own code. :))
<TDavid> from my perspective functions should be used to eliminate repetitive actions and streamline code, but if in the main body of the code you are doing nothing but calling functions, well i'm not sure that is entirely correct. It will work, but I'm thinking why not just have the body of the code without the function call
*** Andy has joined #netsurprise
<FurBall> I remember one of my profs in college said that the best program was one where the main function simply called other functions.  Top down design and all that. :)
*** TiBo has joined #netsurprise
<TDavid> but if you think about that for a minute, why would one do that in a small program?
<FurBall> I agree. :)  Like you, I use functions to stop repetition and streamline but other than that...
<TDavid> in a gigantic program that is executed by only a few people that makes sense, but in a smaller program that is itereated thousands of times i think it brings extra overhead
<FurBall> Now, here's a good point.  :)  Functions add speed/memory overhead.
*** Chris has quit IRC (QUIT: User exited)
*** WillyB has joined #netsurprise
<TDavid> so if we were just calling a function for convenience, well ... it is probably a bit on the wasteful side
<TiBo> Functions are good form.  They make your code easy to read and maintain when you go to update them after a long period of time.
<WillyB> I have to go to the store... but didn't want to be late.. if I talk while I'm gone it's not me
<FurBall> Yes, functions do make your code easier to read BUT at the same time, over functioning your code is a bad thing too.
*** tia has joined #netsurprise
<FurBall> Just like overnormilizing a database is a BAD thing.
<tia> hi all
<FurBall> Hi Tia
<TDavid> i guess that is my point. It's like candy ...  you eat too much your teeth fall out :)
<Andy> Hi Tia
<TDavid> hello tia :)
<FurBall> Willy, I always assume that if you're talking, it's not you.  LMAO
* FurBall ducks
<TDavid> if you look at the code that zuzy posted it makes for excellent discussion about code optimization
* WillyB slaps FurBall around a bit with a large trout
<TiBo> I don't much care about using functions or not using them I just like to be a contrarian.
* FurBall ducks the trout and watches as it hits TiBo upside the head
<FurBall> Whoops.  there I go again causing trouble.  LMAO
<WillyB> I try not to look TD unless I'm stupmed, but now I'll have to go check it out
<TiBo> Back in the days before the torut who'd have ever thought they'd be glad to get smacked by a trout?
<TDavid> (basic) TO-DO ASSIGNMENT: Write a script to submit a username and password to enter a page. 
<FurBall> LOL@TiBo
<TDavid> here is the link to the code in question: http://adultnetsurprise.com/learning_center/help_board/Forum26/HTML/000003.html
<FurBall> EEWWWW!!!!  YUCK!! 
<FurBall> Too many functions IMHO
<TDavid> here is the code we can work on optimizing: 
<TDavid> <?
<TDavid> $total=$username.$password;
<TDavid> if ($total == "") {
<TDavid> echo "<b>Please enter your username and password.</b></p>";
<TDavid> die;
<TDavid> }
<TDavid> (PAUSE for flood)
<TDavid> if ($username == "") {
<TDavid> echo "<b>Form Incomplete:</b><br>You must enter a username.</p>";
<TDavid> die;
<TDavid> }
<TDavid> if ($password == "") {
<TDavid> echo "<b>Form Incomplete:</b><br>You must enter a password.</p>";
<TDavid> die;
<TDavid> }
<TDavid> Now how can we go about doing this form checking without all this repetition and NOT using a function
<FurBall> Whoops!  wrong one. :)
<TDavid> ?
<TDavid> we'll get to the other one, furball :))
<TDavid> btw, zuzy, not picking on you if you are reading these workshop logs :) This is an excellent example for optimization and I am glad you posted :)
* TDavid makes workshop log note
*** _Splitz_ has joined #netsurprise
<TDavid> anybody got any ideas?
<_Splitz_> I got ideas
<FurBall> Well, we can't use PHP's variable variables yet can we. :)
<_Splitz_> I'm not sharing them
* FurBall walks over to Splitz and shakes him around a bit to get his ideas out.
<TDavid> we're doing a workshop, splitz, come back when you are :)
<TDavid> hehe
*** CoolHand has joined #netsurprise
<_Splitz_> FurBall, HELL NO! ;)
*** CoolHand is now known as Cool`Hand
<FurBall> Well, one way would be this:
<FurBall> if ($username = "" || $password = "") { 
<FurBall> echo "<b>Form Incomplete:</b><br>You must enter a username or password.</p>"; 
<FurBall> die;
<FurBall> }
<FurBall> This has the advantage of NOT telling the "hacker" which of the username/password is incorrect. :)
<TDavid> logical OR, yes :)
<_Splitz_> bbl, I'll distract yuns too much
<TDavid> how about echoing back instead of dying and repopping the form
*** _Splitz_ has quit IRC (QUIT: User exited)
<TDavid> if((!$username) OR (!$password)) {
<TDavid> $error = '<font color="red">Username or Password field left blank></font>';
<TDavid> } 
*** WillyB is now known as WillyBrb
<FurBall> echoing back what?  The rest of the form?  It's getting displayed either way isn't it?
<TDavid> nope, because the idea was to allow them to be allowed inside on the same page with the login
<TDavid> it was a bit of a tricky assignment, but demonstrates how you can display multiple content on a single page without needing to include or require other scripts
<TDavid> if the user/pass is good you let them into the content, if it is bad, you pop the form with the error
<Cool`Hand> can u get viruses in zip files?
<TDavid> the login form
<FurBall> OK... however, with the code that Zuzy posted, the form gets displayed first and then the PHP code gets displayed.
<TDavid> yes, and it is incorrect
<FurBall> OK. :)  My misunderstanding then. :)
<TDavid> Write a script to submit a username and password to enter a page. If the username and password does not match the variable hardcoded in the script show the login form again with an error message. The password field should be private so that as you type you'll see ****. This should all be one self-contained script with NO include() or require() files
<TDavid> that is the entire to-do assignment
*** WillyBrb has quit IRC (Ping Timeout)
<Cool`Hand> do alot of you run pay sites?
<Cool`Hand> maybe i will add a pay sites section to my site
<CrEaToR> we are in the middle of a workshop Cool`Hand
<Cool`Hand> workshop?
<TDavid> grrrr
<FurBall> Cool`Hand, this is a workshop on PHP.
<Cool`Hand> ah ok sorry
<Cool`Hand> is that just tonight?
<TDavid> boy, i wish i had ops in this channel hehe so i could change the topic :)
<FurBall> :)
<TDavid> surprisebot, change the topic!! hehe :)
<CrEaToR> there is a schedule for the workshops at www.adultnetsurprise.com
<TDavid> ok, back to the discussion ...
<TDavid> as you can see the form should be embedded inside a conditional
<TDavid> i like the idea of populating a variable named $error
<TDavid> if $variable is populated they always get the form OR if the hidden form doesn't indicate it is a login
<TDavid> er if $error is populated that is
<FurBall> :)
<TDavid> and if it is a login and they match the hardcoded login info then they get the content
<TDavid> all on one page
*** ConePup has joined #netsurprise
<TDavid> hi pup
<TDavid> <?
<TDavid> // define correct login
<TDavid> $correct_username = 'test';
<TDavid> $correct_pass = 'test';
<TDavid> if($action == "login") {
<TDavid> // proceed with verifying password
<TDavid> }
<TDavid> ?>
<ConePup> hi TDavid
<Cool`Hand> cya later all
*** Cool`Hand has quit IRC (QUIT: User exited)
<TDavid> Next we can test for blank forms all in one if statement using the logical OR instead of using multiple ones. Let's do that next:
<TDavid> if((!$username) OR (!$password)) {
<TDavid> $error = '<font color="red">Username or Password field left blank></font>';
<TDavid> }
<TDavid> else {
*** Andy has quit IRC (Connection reset by peer)
<TDavid> next we verify if the password and username match
<TDavid> if(($username == $correct_username) AND ($password == $correct_password)) {
<TDavid>  // this is where we escape and show content
<TDavid>  ?>
<TDavid>   Congrats you have logged in correctly!
*** ConePup has quit IRC (QUIT: User exited)
<TDavid> if the username wasn't correct then we have another error situation
<TDavid> <?
<TDavid>  } else {
<TDavid>   $error = '<font color="red">Username or Password <b>invalid</b></font>';
<TDavid>  }
*** TiBo is now known as TiBo-brb
<FurBall> Umm, shouldn't your first else be an elseif?
<TDavid> nope, because this is inside the whether or not the username/pass is valid
*** WillyB has joined #netsurprise
<TDavid> if they both don't match they didn't provide the correct username/pass
<FurBall> K. Then you're missing a close curly somewhere. :)
<TDavid> we are also still inside the $action="login" conditional
<TDavid> yes, you are correct, that is next
<FurBall> K.  Jumping the gun am I.  LMAO
<TDavid> that is the end of the $action"login" ... but very perceptive! :))
<TDavid> } // end of $action="login"
<FurBall> Umm, no.  We need to have a close curly to close the second if statement.
*** zuzy has joined #netsurprise
<TDavid> hmmm, did something get cut off?
<FurBall> I think it did. :(
<TDavid> bummer!
<FurBall> you need one more close curly right before } else {
<TDavid> i'll post to the bbs in its entirety
*** legaldoc has joined #netsurprise
<FurBall> (by the way, for the logs, a close curly is '}')
<WillyB> Hi zuzy.. your ears musthave been ringing
<zuzy> huh?
<TDavid> hi zuzy, we're working on your code right now :) trying to make it shorter for you
<zuzy> Hi by the way
<FurBall> Hi Zuzy!
<zuzy> oh my i just go here no idea what you talked about
<TDavid> ok, i will start from the beginning with that code ...
<TDavid> <?
<TDavid> // define correct login
<TDavid> $correct_username = 'test';
<TDavid> $correct_pass = 'test';
<TDavid> if($action == "login") {
<TDavid> // proceed with verifying password
<TDavid> }
*** floppy has joined #netsurprise
<TDavid> remove that squiggily
<floppy> Howdy ;)
<WillyB> hi floppy
<TDavid> hi floppy
<TDavid> <?
<TDavid> // define correct login
<TDavid> $correct_username = 'test';
<TDavid> $correct_pass = 'test';
<TDavid> if($action == "login") {
<TDavid> // proceed with verifying password
<TDavid> there we go hehe
<FurBall> OK!  :)
<TDavid> now we are inside the $action loop
<TDavid> inside here we will test the username and password if they are blank first
*** legaldoc has quit IRC (QUIT: User exited)
<TDavid> if((!$username) OR (!$password)) {
<TDavid> $error = '<font color="red">Username or Password field left blank></font>';
<TDavid> } else {
<TDavid>   // does password and username match?
<TDavid>   if(($username == $correct_username) AND ($password == $correct_password)) {
<TDavid>  // this is where we escape and show content
<TDavid>  ?>
<TDavid>   Congrats you have logged in correctly!
<TDavid> <?
<TDavid>  
<TDavid> } else { // keeping those brackets in order now we know they didn't login correctly
<TDavid> $error = '<font color="red">Username or Password <b>invalid</b></font>';
<TDavid>  }
<TDavid> lastly we need to close the $action = "login" conditional
<TDavid> } else { // ok we need to make $error say that the user should please login because it's the first time in
*** tia has quit IRC (QUIT: User exited)
<TDavid> $error = '<center>Please Login</center>';
<TDavid> ?> // escape php to print the login
<TDavid> <form name="test" method="post" action="password.php">
<TDavid> <input type="hidden" name="action" value="login">
<TDavid> <input type="text" name="username">
<TDavid> username
<TDavid> <input type="password" name="password">
<TDavid> password
<TDavid> (ive got the HTML a little wacky here, just adding comments to it)
<TDavid> <input type="submit" value="login">
<TDavid> </form>
<TDavid> <? // restart php to close the else loop
<TDavid> echo($error);
<TDavid> } // close else
<TDavid> now you have a self-contained script with 3 parts changing one variable to be an error or a login message and not using functions
<TDavid> and the content can be maintained on the same page and PHP will either print the login or content or redisplay the login based on a match of the hardcoded login/pass info
<zuzy> that's a lot better of cause, thanks
<TDavid> i will post this to the bbs as well for you, zuzy, but i am glad you posted the code :) it makes for great study :))
*** CrEaToR has quit IRC (Connection reset by peer)
<zuzy> Well well if you can't be a good sample be a dandy bad one
<zuzy> classes are more fun that way
*** CrEaToR has joined #netsurprise
<zuzy> are we going into sending e-mail next week?
<FurBall> LOL
<zuzy> I really want to make a mailing list for my sites
<TDavid> yes :)
<zuzy> oh, fun!
*** idahoen has joined #netsurprise
<WillyB> man, is the net screwy today or is my system at 1% resources
<TDavid> willyb you having some system resource probs?
<FurBall> net's probably messed up willyb. :(
<TDavid> ok the complete code is posted on the BBS
<TDavid> http://adultnetsurprise.com/learning_center/help_board/Forum26/HTML/000003.html
<WillyB> Actually, sys is at 51%,  but it takes a while for my typing to show up on the line down here
<TDavid> that should make it easier to follow then all the line breaks and the annoying <TDavid> inserted between it lol
<TDavid> willyB, have you had a chance to mess with the forms yet, bro?
<zuzy> does this mean I missed most of the class?
<TDavid> well it will all be in the logs for you :)
<TDavid> did you have some other questions about this week's material, feel free to ask :)
<TDavid> or prior week's material as well
<WillyB> no I sure haven't TDavid.. it's been a busy week-end here.. I
<zuzy> say pacific is  minus what GMT?
<WillyB> 've read the lesson twice so it wont be long :)
<WillyB> 7 I think zuzy
<zuzy> thanks well got to run make dinner see you all next time hoplully i'll get here earlier
<WillyB> see ya zuzy :)
*** zuzy has quit IRC (QUIT: User exited)
<TDavid> gmt-8 = pacific
*** Chris has joined #netsurprise
<FurBall> TDavid, i think you're still missing a close curly somewhere around the <? } else { $error = "username invalid" lines.  I dont' think you're closing the login code.
<FurBall> bye zuzy
<TDavid> did you check the bbs, furball?
<FurBall> Yes I did.   
<FurBall> I may be wrong though. :)  
<TDavid> count the } and the { and see if they match :)
<floppy> I ll get to it tommrow and catch up TD :)) good day for it tommrow skidder broke and they shiped the wrong part 
<FurBall> I did.  I come up one close short. :)
*** Steve is now known as Steve-Away
<floppy> Hi willyB
<TDavid> i get 6 } and 6 {
<WillyB> bummer floppy
<TDavid> maybe you are missing the one long line ... AND ($password == $correct_password)) {
<TDavid> kind of easy to miss that one
<Snikks_Wurkz> WillyB!!! Whats up pilgrim?
<WillyB> Hi ya snikks
<TDavid> i came up with 5 { at first when just counting now hehe and then I spotted that one, furball
<WillyB> I got 7 and 6 TD
<Snikks_Wurkz> :)
<TDavid> 7 what? hehe
<TDavid> { or }
<FurBall> Hmm... I'm throwing it into an editor now.  :)
*** Chris has quit IRC (QUIT: User exited)
<WillyB> Snikks, just gettin down of my high horse and walking on the ground for a while :) hehehe
<TDavid> heaven knows im not perfect, might be a bug here, this is on the fly coding hehe :)
<Snikks_Wurkz> lol
<WillyB> you have to read that with a John Wayne accent floppy hehehe
<TDavid> but for the logs we should get it right, so let me know furball if they don't match up
<floppy> lmao 
<Snikks_Wurkz> you got it Willy
<floppy> I always do willy 
* floppy snikks definatley does lol
<WillyB> 7 {
<Snikks_Wurkz> :) hehehe
<FurBall> Will do.  Checking it now. :)
<floppy> anyone know how to stop that knocking on icq when some one new is online other that turn down the volume ??
<TDavid> actually this raises a good point about nested conditionals, they can be a bit tricky at times
<FurBall> Yup.  There's a missing curly.
<FurBall> I get a parse error on line 21. which is this:    } else {
<FurBall>      $error = 'Please login';
<FurBall>    }
* Snikks_Wurkz sticks a pot seed under the space bar of floppys keyboard while he isn't looking and runs and hides
<floppy> haha
<floppy> really 
<Snikks_Wurkz> :)
<floppy> it does
<WillyB> 1 in second block, 4 in 3rd block and 2 in last block TD {'s
<Snikks_Wurkz> hehe
*** trouble has joined #netsurprise
<Snikks_Wurkz> trouble!!!!
<trouble> hey Snikks
<Snikks_Wurkz> :)
<trouble> : )
* floppy ut oh now we a re all in trouble
<WillyB> Hi trouble :)
<WillyB> trouble is good for the mind and body :))
<WillyB> getting caught in trouble is not!
<Snikks_Wurkz> lol
*** Da_MoBu has joined #netsurprise
<Da_MoBu> hi all
<WillyB> hi Da_MOBu
<Snikks_Wurkz> TW licked her head to toe this morning
<Snikks_Wurkz> lol
<FurBall> OK.  Here we go.  :)  
<WillyB> hehehehe
<trouble> hi willyb
<Da_MoBu> i cant get any good traffic :-( grr... i dunno whats wrong
<FurBall> here's code that works.
<FurBall> <?
<FurBall> // define correct login
<FurBall> $correct_username = 'test';
<FurBall> $correct_pass = 'test';
<FurBall> if($action == "login")
<FurBall> {
<FurBall>   // proceed with verifying password
<FurBall>  if ((!$username) OR (!$password))
<FurBall>    {
<FurBall>      $error = '<font color="red">Username or Password field left blank></font>';
<FurBall>    }
<FurBall>  else
<FurBall>      {
<FurBall>      // does password and username match?
<FurBall>      if (($username == $correct_username) AND ($password == $correct_password))
<FurBall>        {
<FurBall>        // this is where we escape and show content
<FurBall>   ?>
<FurBall> <p>Congrats you have logged
<FurBall> hello? did i get ignored? :)
<WillyB> what sort of sites do you have MoBu?
<FurBall> OK.  Umm, I think I'll post it to the bbs. :)
<WillyB> It is really hard to read in here FurBall :(  TD is looking for the extra { I think too hehehe
<TDavid> im looking at it
<Da_MoBu> so hmm.. PHP looks pretty much alot like C++
<TDavid> yup
<FurBall> Yeah, I'm gonna post it on the BBS. :)
<Da_MoBu> oo thats good
<FurBall> K.  It's there now.
<TDavid> http://www.scriptschool.com/php/test_5.txt
<TDavid> much easier to look at it here hehe
<trouble> TDavid..Toson said that she will be online soon if you need to talk to her
*** TiBo-brb is now known as TiBo
<trouble> hi TiBo
<TiBo> Hi Trouble.
<Snikks_Wurkz> TiBo whazup dude?
<WillyB> Hi ya TiBo
<FurBall> :)
*** idahoen has quit IRC (QUIT: User exited)
<TiBo> Not too much, just hangin out.
<Snikks_Wurkz> :) nods head
*** sharkysr has joined #netsurprise
<trouble> hi sharkysr
<WillyB> shardysr!
<Snikks_Wurkz> Back to work cyas
<floppy> hey sharkysr
<sharkysr> Damn, I must be spacin'   I went to the wrong place again
<WillyB> typo willyB
<FurBall> Hey Sharkysr, trouble, Tibo
<WillyB> see ya snikks
<sharkysr> hey trouble floppy FurBall
<FurBall> bye snikks
<trouble> bye Snikks
<sharkysr> Hello TD...
<floppy> sharky message on icq 
<TDavid> hi sharkysr
<sharkysr> Haven't even turned that on today.
<TDavid> http://www.scriptschool.com/php/test_5.php
<trouble> hi floppy
<TDavid> http://www.scriptschool.com/php/test_5.txt
<TDavid> it's all good :)
<TiBo> Howdy Sharkysr.
*** Chris has joined #netsurprise
<sharkysr> Hiya TiBo
<trouble> hi Chris
<Chris> hiya
<WillyB> cool TD :)  now theirs 7 }'s too :)
<TDavid> something must have been missing in the cut and pastes i kept doing lol
<FurBall> Yup.  LOL
<TDavid> well i guess that is a good example of how multiple conditionals can be tricky hehe
<sharkysr> So, did I miss anything TD?
<FurBall> Yes it is. :)  I always count my opens and closes (both for parens and curlys) on my hands. :)  If you have more than 5 opens, you've got some complicated code.  ;-)
<WillyB> Something still wrong with it though
<TDavid> what's that, willyB?
<TiBo> I always write a close paren for every open parent and then go back and type in in layers.
<TiBo> I'm very systematic that way.
<sharkysr> That is why I like home site.  I do a search for the open tag, and for the close tag, and if the count is the same on both, then chances are I didn't miss any.  Not perfect, but close.
<WillyB> I type in the wrong pass and it says error, etc.. but then I typ in the right user pass and it still gives the error.. I have to refreash it for it to work
<TiBo> Or retentive.  Whichever adjective you like best.
<FurBall> I usually have an editor that puts the close paren and it also puts the open and close curly's when I need em. :)  I'm lazy that way.  :)  
<WillyB> same if I t;yp the correct stuff in and then back up and type the wrong usrpass in, it still takes me to where it should
<FurBall> TiBo, I would NEVER use the word retentive to describe you.  :)
<WillyB> hehehe FurBall!
<TDavid> yeah, you know why?
<TDavid> hehe
* TiBo just sits there looking indignant
<TDavid> $correct_pass should be $correct_password 
<TDavid> fixed now
<Chris> woooooooo 106k/s from cnet, just thought i had to share :)
<WillyB> ah, ok.. I see that
<FurBall> that brings up a good question TDavid.  In perl, you have what's called a strict mode.  Basically, it checks and makes sure that you have predeclared all of your variables.
<FurBall> Does PHP have a similar mode?
<TDavid> im not sure on that one, furball
<WillyB> in the else statement TD
* FurBall throws torut guts onto TiBo so that he has a REAL reason to sit there looking indignant. <EG>
<TDavid> well we have had a real debugging session during the workshop today ... nice :)
<TDavid> we needed one of those lol
* TiBo sits there looking so cool and calculating is frightening.
<WillyB> How hard would it be to write a function to do that FurBall?
<TDavid> wouldn't be like real programming without it lol
<WillyB> hehehe TD!
<FurBall> LMAO!  Yup.  Haven't had a good debugging session in a while.  We're due. LOL
<FurBall> Willy, umm, don't think that you could write the function in PHP, you'd have to embed it into the interepreter itself.  
<WillyB> I'm sure we'll have more when I start posting in the later weeks of the course! LOL!
<TDavid> i'll catch you guys over in script school ... this brings the workshop to an end
* TDavid closes log
<TiBo> All these languages need a good IDE with a full featured debugger.
