Im attempting at making my own comic engine - PHP-Editors

Im attempting at making my own comic engine...

This is what ive made so far. It half works....

Baiscly, the question is, how do i stop it excecuting the button scripts everytime the page loads(Thats my problem).(So when i have both Prev and Next on the page nothing happens, but when i have only 1, it excecutes fine(except if i refreash bthe page, it still does next/prev :P)

Code:

<?php
session_start();
session_register("comic");
if ($_SESSION['comic'] < 1){$_SESSION['comic'] = 1;}
echo $_SESSION['comic'];
?>
<body>
<img src="comic/<?=$_SESSION['comic']?>.jpg">

<form name="form1" method="post" action="<? $_SESSION['comic']++?>">
  <input type="submit" name="Next" id="Next" value="Next">
</form>
<form name="form2" method="post" action="<? $_SESSION['comic']--?>">
  <input type="submit" name="Prev" id="Prev" value="Prev">
</form>
</body>

Im really new to this sorry guys. This is the second script ive ever made.... (Although my first one is awesome, its a benchmarker for Server's and Browsers... My script found that Opera(9.5) is the fastest, then IE7 is second fastest, and Firefox(3 and 2) was slowest.)

Oh and making it a GET_ variable would be cool to if you guys could show me how to convert it

.(You know, so if someone visits www.blahblah.com/blah.php?=5, it would be the 5th comic and stuff. Thanks!

)

I had a huge long reply with explanation on everything(And then i accedentally quit opera), but anyway, for future refrence this is the solution.

Code:

<?php
session_start();
session_register("comic");
if ($_SESSION['comic'] < 1){$_SESSION['comic'] = 1;}

$Next_Prev = $_POST['Next_Prev'];
switch ($Next_Prev)
{
case 'Next':
$_SESSION['comic']++;
break;
case 'Prev':
if ($_SESSION['comic'] == 1){$_SESSION['comic'] = 1;}else {$_SESSION['comic']--;}
break;
}

echo $_SESSION['comic'];
?>

<body>
<img src="comic/<?=$_SESSION['comic']?>.jpg">

<form name="Next_Prev" method="post" action="">
  <input type="submit" name="Next_Prev" id="Next" value="Next">
  <input type="submit" name="Next_Prev" id="Prev" value="Prev">
</form>
</body>

My finnished comic engine project(Ill be making a theme engine for it soon enough)

comic.php

Code:

<?php
session_start();
session_register("comic");
require("config.php");
if ($_SESSION['comic'] < 1){$_SESSION['comic'] = 1;}
//print count(glob($comic_dir . "/*." . $ext . ""));
$Next_Prev = $_POST['Next_Prev'];
switch ($Next_Prev)
{
case 'Next':
$_SESSION['comic']++;
break;
case 'Prev':
if ($_SESSION['comic'] == 1){}else {$_SESSION['comic']--;}
break;
case 'First':
$_SESSION['comic'] = 1;
break;
case 'Latest':
$_SESSION['comic'] = count(glob($comic_dir . "/*." . $ext));
break;
}
echo $_SESSION['comic'];
?>
<body>
<img src="comic/<?=$_SESSION['comic']?>.jpg">
<form name="Next_Prev" method="post" action="">
  <input type="submit" name="Next_Prev" id="First" value="First">
  <input type="submit" name="Next_Prev" id="Prev" value="Prev">
  <input type="submit" name="Next_Prev" id="Next" value="Next">
  <input type="submit" name="Next_Prev" id="Latest" value="Latest">
</form>
</body>

config.php

Code:

<?php
// The directory of the comic's.
$comic_dir = "comic";
//The file extension your comics use.
$ext = "jpg";
?>

But for tyhis to be fully complete i need to know how to GET_ the comic variable.

$_GET is just an array, so print_r($_GET); will show you everything in it.

You access it just like an array as well. so $_GET["comic"] is the value that is in the URI as comic=5. So $_GET["comic"] returns 5

Yeah i understand that bit, but im not sure how to intergrate it with my buttons. Eg, when i press Next from comic 5, it will go to comic 6.

Ive sorta cheated out of it via session.

So how do i get around this?

Thanks in advance!

Its already done.

Instead of using $_SESSION["comic"] just use $_GET["comic"]. They do the same exact function in your case.

Uhhh, nah, it doesnt work

Code:

<?php
session_start();
session_register("comic");
require("config.php");
if ($_GET['comic'] < 1){$_GET['comic'] = 1;}
$count = count(glob($comic_dir . "/*" . $ext));
$Next_Prev = $_GET['Next_Prev'];
switch ($Next_Prev)
{
case 'Next':
$_GET['comic']++;
break;
case 'Prev':
if ($_GET['comic'] == 1){}else {$_GET['comic']--;}
break;
case 'First':
$_GET['comic'] = 1;
break;
case 'Latest':
$_GET['comic'] = $count;
break;
}
echo $_GET['comic'];
?>
<html>
<body>
<center>
<p><img src="comic/<?=$_GET['comic'] . $ext?>"></p>
<form name="Next_Prev" method="get" action="">
  <input name="Next_Prev" type="submit" class="test" id="First" value="First">
  <input type="submit" name="Next_Prev" id="Prev" value="Prev">
  <input type="submit" name="Next_Prev" id="Next" value="Next">
  <input type="submit" name="Next_Prev" id="Latest" value="Latest">
</form>
</center>
</body>
</html>

It does comic.php?Next_Prev=First, when i press First, and comic.php?Next_Prev=Next, when i press next.

Not comic.php?Comic=23
