Problem with gd script

[Ozzapoo]

Hey. I was trying to make a script that would allow me to generate images using gd, however I do not know what is wrong with it. It doesn't display and error but it doesn't generate an image either! Please have a look at it and tell me what's wrong

 

<?php

$width = $_POST['width']; 
if($width > 800) {
exit("Width is greater than 800"); }

$height = $_POST['height']; 
if($height > 500) {
exit("Height is greater than 500"); }

$type = $_POST['type'];
if ($type == "jpeg") { header ("Content-type: image/jpeg"); } elseif($type == "png") {header ("Content-type: image/png"); } elseif($type == "gif") 

{header ("Content-type: image/gif"); } else {exit("ERROR: Unknown Filetype?"); }

$bcolour = $_POST['bcolour']; 

$handle = ImageCreate ($width, $height) or die ("Cannot Create image"); 
if($bcolour = "white") { $bg_color = ImageColorAllocate ($handle, 255, 255, 255); } //white
elseif($tcolour = "red") { $bg_color = ImageColorAllocate ($handle, 255, 0, 0); } //red
elseif($tcolour = "blue") { $bg_color = ImageColorAllocate ($handle, 0, 0, 255); } //blue
elseif($tcolour = "green") { $bg_color = ImageColorAllocate ($handle, 0, 192, 0); } //green
elseif($tcolour = "yellow") { $bg_color = ImageColorAllocate ($handle, 255, 255, 0); } //yellow
elseif($tcolour = "orange") { $bg_color = ImageColorAllocate ($handle, 255, 153, 0); } //orange
elseif($tcolour = "lblue") { $bg_color = ImageColorAllocate ($handle, 173, 216, 230); } //light blue
elseif($tcolour = "purple") { $bg_color = ImageColorAllocate ($handle, 160, 32, 240); } //purple
else {exit("Unidentified Background Colour!"); }
$tcolour = $_POST['tcolour']; 
if($tcolour = "white") { $txt_color = ImageColorAllocate ($handle, 255, 255, 255); } //white
elseif($tcolour = "red") { $txt_color = ImageColorAllocate ($handle, 255, 0, 0); } //red
elseif($tcolour = "blue") { $txt_color = ImageColorAllocate ($handle, 0, 0, 255); } //blue
elseif($tcolour = "green") { $txt_color = ImageColorAllocate ($handle, 0, 192, 0); } //green
elseif($tcolour = "yellow") { $txt_color = ImageColorAllocate ($handle, 255, 255, 0); } //yellow
elseif($tcolour = "orange") { $txt_color = ImageColorAllocate ($handle, 255, 153, 0); } //orange
elseif($tcolour = "lblue") { $txt_color = ImageColorAllocate ($handle, 173, 216, 230); } //light blue
elseif($tcolour = "purple") { $txt_color = ImageColorAllocate ($handle, 160, 32, 240); } //purple
else {exit("Unidentified Text Colour!"); }



$tbeginX = $_POST['tbeginX']; 
$tbeginY = $_POST['tbeginY']; 
$size = $_POST['size']; 
$text = $_POST['text']; 

ImageTTFText ($handle, $size, 0, $tbeginX, $tbeginY, $txt_color, "fonts/arial.otf", $text); 

if ($type == "jpeg") { ImageJpg ($handle); } elseif($type == "png") {ImagePng ($handle); } elseif($type == "gif") {ImageGif ($handle); } else {exit

("ERROR: Unknown Filetype?"); }



?>

 

This script was based on the following code, which DOES work ( meaning gd does work on my computer )

 

<?php 
header ("Content-type: image/png"); 
$handle = ImageCreate (220, 65) or die ("Cannot Create image"); 
$bg_color = ImageColorAllocate ($handle, 255, 0, 0); 
$txt_color = ImageColorAllocate ($handle, 0, 0, 0); 
ImageTTFText ($handle, 35, 0, 15, 40, $txt_color, "fonts/bsps.otf", "test"); 
ImagePng ($handle); 

//The first parameter is our handle, then font size, rotation, starting X, starting Y, text color, font, and finally our text.
?>

error_reporting(E_ALL);

Put that someone and see what happens....

As derrick said add to the top of your code:

 

error_reporting(E_ALL);
ini_set('display_errors', true);

 

If you're testing it with a jpg image, it won't work because the function is

 

ImageJpeg, you used ImageJpg, which doesn't exist. Change it to ImageJpeg and see if it's any better.

Thanks guys!! I fixed it! I messed around with it so much that I accidentally swapped one of the values around ><
