PHP 5.2.3 imagecreatetruecolor Problem

[1bradillac]

I've been having non-stop problems with creating an Image uploading script that resizes to a certain size and name and then inputs it into a database along with a bunch of other information.

 

I have it running perfectly on my own computer, running the latest version of MAMP w/ PHP v5.2.0 installed.

 

When I try to upload it to my server (running PHP v5.2.3), the first error I got was it wouldn't allow me to use exif_imagetype() to look at the image type, so I just replaced it with a substr(). The next problem is that, even though it uploads the original image, it doesn't resize the image. I'm not sure whether it is getting stuck on the Content-Type, or on the imagecreatetruecolor() (both of which have popped up as errors in various tests.

 

At the moment when I submit the script, it goes to a page with a broken-image (Due to some problem with the Content-Type part) rather than resizing and continuing to the index page. 

 

 

Here is the code below, any help would be supremely appreciated. Sorry if it's hard to follow without comments.  :-X

 

 

// Function out of functions.php

 

 

function func_upload_image($name, $dir, $newname)

{

 

$original_filename = basename($_FILES[$name]["name"]);

if (substr($original_filename , -4) == ".gif" || substr($original_filename, -4) == ".GIF")

{

$filename = "../" . $dir . $newname . ".gif";

$dbfilename = $dir . $newname . ".gif";

}

 

if (substr($original_filename, -4) == ".jpg" || substr($original_filename, -4) == ".JPG")

{

$filename = "../" . $dir . $newname . ".jpg";

$dbfilename = $dir . $newname . ".jpg";

}

 

$_FILES[$name]["tmp_name"];

 

move_uploaded_file($_FILES[$name]["tmp_name"], $filename);

 

$area = getimagesize($filename);

 

 

$width = 300;

$height = 120;

 

 

 

 

 

if (substr($filename, -4) == ".gif" || substr($filename, -4) == ".GIF")  {

 

header("Content-Type: image/gif");

 

list($width_orig, $height_orig) = getimagesize($filename);

 

$ratio_orig = $width_orig/$height_orig;

 

if ($width/$height > $ratio_orig) {

  $width = $height*$ratio_orig;

} else {

  $height = $width/$ratio_orig;

}

 

$image_p = imagecreatetruecolor($width, $height);

$image = imagecreatefromgif($filename);

imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $width_orig, $height_orig);

 

imagegif($image_p, $filename, 80);

 

 

}

 

 

if (substr($filename, -4) == ".jpg" || substr($filename, -4) == ".JPG")  {

 

 

header("Content-Type: image/jpeg");

 

list($width_orig, $height_orig) = getimagesize($filename);

 

$ratio_orig = $width_orig/$height_orig;

 

if ($width/$height > $ratio_orig) {

  $width = $height*$ratio_orig;

} else {

  $height = $width/$ratio_orig;

}

 

 

$image_p = imagecreatetruecolor($width, $height);

$image = imagecreatefromjpeg($filename);

imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $width_orig, $height_orig);

 

imagejpeg($image_p, $filename, 80);

 

}

return $dbfilename;

 

 

}

 

 

 

 

 

// In addnews.php

 

if ($_FILES["news_img"]["name"] != "") {

$result = mysql_query("SELECT * FROM news ORDER BY id DESC");

$row = mysql_fetch_array($result);

$newid = $row["id"];

$newid++;

$img = func_upload_image("news_img", "images/news/", $newid);

 

}

 

$currentdate = date('Y-m-d H:i:s');

mysql_query("INSERT INTO news (postdate, body, img, ip, userid, lastuserid, lastip, lastdate, display) VALUES ('$currentdate', '$_POST[news_body]', '$img', '$_SERVER[REMOTE_ADDR]', '$_SESSION[id]', '$_SESSION[id]', '$_SERVER[REMOTE_ADDR]', '$currentdate', '$_POST[news_display]')");

 

header("Location: index.php");

alter as needed see first if it works ok.

Nope. Doesn't work. Same problem actually. It uploads the original, but refuses to do the imagecreatetruecolor.
