GD Generation

[phat_hip_prog]

Hi, i'm playing with a small cms. It uses mod_rewrite to redirect to an index, however in certain circumstances I want to generate images using gd, needing to send appropiate headers first i've put a clause in very early, even before 'session_start()'. Instead a function which generates and returns an image is called. However all I get is the filename, why?

 

I've tested the image creation in files outside the cms and it works fine... But inside the cms it borks!

 

Here's how i've simplified it for tests:

index.html

<?php
include("monkey/inc.php");

$iret = inc_init();
if($iret != -1)
{
print inc_draw();	//	generate page
}
?>

 

Here's the 'inc_init()' and 'draw_img()' functions:

monkey/inc.php

function draw_img()
{
header("Content-type: image/jpeg");
$w = 230;	$h = 45;
$im = ImageCreate($w, $h);
$red = ImageColorAllocate($im, 255, 50, 50);
//	DRAW BACKGROUND
ImageFilledRectangle($im, 0, 0, $w, $h, $red);
//	OUTPUT TO BROWSER
ImageJpeg($im);
}

function inc_init()
{
//	CHECK IMAGE GENERATOR OVERRIDE
if (isset($_GET["page"]))
{
	$p = $_GET["page"];
	$lret = split_url($p);	//	dir, dirs, fn, bn, ext
	if ($lret['dirs'][0] == "img")
	{
		draw_img();
		return -1;
	}
}

//	LOAD MODS
inc_load_mods();
...
...

 

Can anyone tell me why all i'm getting is the filename printed to screen?

 

Cheers!

Treat php-generated images as you would any other image file.

 

Put the gd code in a separate php file, say, myimage.php, and place it on the page with an image tag, eg

 

<img src='myimage.php'>

Because of the way i've got mod_rewrite setup I can't just call the file. I've tried calling the file using both 'include()' and 'eval()', both ways give the same result. But from what I see theres no real need to have them in a seperate file?

 

any more for any more?

What!!!

 

don't include it or anything

 

just use <img src='myimage.php'>

[phat_hip_prog]

It is called like that (<img src='img/myimage.php'>), then mod_rewrite translates it to 'index.html?page=img/myimage.php', $page is then split and checked, when discoved it's 'img', either the file is included or the function called. This is all done as if it was in a file on it's own?
