Hi to all,
Firstly I must state my knowledge of php is limited but I am a quick learner. I have taken on the task of finishing a friends website due to his untimely passing and have hit a problem with the completion of his work.
The site involves the uploading of a picture, jpg, png or gif. as part of an order process. The files involved are called order.php, step1.php and then step2.php.
The picture uploads to the upload folder, (called uploads), ok and step1.php is called/initiated but then fails to move to step 2. Once the picture is uploaded it is supposed to have a thumbnail produced which is to be stored in a serperate folder, called thumbs, and this is used in step2.php. The thumbnail is not being created and step2 is not called.
Some info that may be useful, is that the site has just been moved to a dedicated server. I'm not sure if this would make any difference.
It is a linux based server but then the old one was too.
The upload folders have full permissions
I have added the -
-
<?php
-
error_reporting(E_ALL);
-
ini_set('display_errors', True);
-
?>
-
-
to the step1.php file and this reported the following error. -
-
Fatal error: Call to undefined function imagecreatefromjpeg()
-
-
If the file is a gif or png then the error differs in relation to the upload file type.
Here is the section of code where this line reports to. -
-
if ( (strtolower($ext)=="jpg") || (strtolower($ext)=="jpeg") ) {
-
$imgOriginal = imagecreatefromjpeg($storePath);
-
-
} elseif (strtolower($ext)=="gif") {
-
$imgOriginal = imagecreatefromgif($storePath);
-
-
} elseif (strtolower($ext)=="png") {
-
$imgOriginal = imagecreatefrompng($storePath);
-
-
} else {
-
debug("Uploaded file didn't appear to be a web safe image.");
-
-
ob_end_flush();
-
exit(0);
-
}
-
-
I am not sure if this is enough information so I will add the entire step1.php for assistance. -
-
<?php
-
error_reporting(E_ALL);
-
ini_set('display_errors', True);
-
?>
-
-
-
<?php
-
session_start();
-
ob_start();
-
-
// javascript was required so the user will never use the degraded version
-
$used_degraded = false;
-
-
// my debug function. comment out the echo's to stop showing the debug text
-
function debug($details) {
-
if ($details != "") {
-
echo $details . "<br />";
-
} else {
-
echo "<hr />";
-
}
-
}
-

Sorry if this is a bit long but I wanted to provide everyone with as much info as possible.
Many thanks

Additional.
I have noticed in phpmyadmin that i have 2 warning messages. I'm not sure if they will have anything to do with my problem.
The mbstring PHP extension was not found and you seem to be using a multibyte charset. Without the mbstring extension phpMyAdmin is unable to split strings correctly and it may result in unexpected results.
and
Your PHP MySQL library version 5.0.27 differs from your MySQL server version 5.0.22. This may cause unpredictable behavior
Again many thanks

Yikes. That post is too long, so I didn't read all of it. I did notice that you said that you got an error stating that imagecreatefrom jpeg() doesn't exist. This means that the GD library is not properly set up.
What PHP version are you using?

Again I do apologise for the lenght. I looked into posting an image of the code but it didn't workout.
Thanks for the response though.
I have called phpinfo.php and it says php version 5.1.6.
Is this the right info you require?

Mmhmm.
Is this local or hosted? If it's hosted, you'll need to talk with your host about why they do not have the GD library installed, as it is standard with PHP5.

Hi
It is hosted but on a dedicated server. I have just transfered it to the dedicated as this is what my friend was about to do. Would this mean that I have to install the GD library myself?
Thanks.

Heya, badvoc.
If you've got a dedicated server, then it would likely be up to you to reconfigure PHP. You can get in touch with your hosting support team to see if they'll do it for you (for free, at any rate).

Cheers for the reply. I am sorry but I am a total noob at this. I have rang my support team and they are not able to give support on phpadmin other than what they have in their documentation, this only gives brief details, download the latest version of phpadmin, unzip it, rename the folder and ftp it to the server. I have done this and can contect to the database fine. Its just when my site comes to image manipulation thats I get the error message.
I don't seem to be having much luck in finding a no nonesense idiots guide to getting the GD library configured in my phpadmin. The old server, a shared host, is running v2.6.0, the latest is 2.11.0. (If I am stating the obvious, apologies). I am lead to believe that the GD libs are not standard with this release, are they with any release?
Is there a way that I can download them and then ftp them to the server. Or is it more technical that that.
Many thanks for you help.

Heya, badvoc.
Alrightey. First thing to do is to create a new page on your server:
Run that script and copy what comes up next to 'configure'.
For example (yours will very likely look different than this): -
'./configure' '--cache-file=config.cache' '--enable-shared' '--disable-static' '--with-apxs2=/usr/local/apache2/bin/apxs' '--with-libxml-dir=/usr/local' '--with-openssl=/usr/local/ssl' '--with-pcre-regex=/usr/local' '--with-zlib-dir=/usr/local' '--with-db4=/usr/local/berkeleydb' '--with-libxml-dir=/usr/local' '--with-jpeg-dir=/usr/local' '--with-png-dir=/usr/local' '--with-freetype-dir=/usr/local' '--with-gd' '--with-iconv=/usr/local' '--with-mysql=/usr/local/mysql' '--with-curl' '--enable-mbstring'
-
Next, download the latest release of PHP to your server. SSH into your dedicated server and type: -
curl http://www.php.net/get/php-5.2.4.tar.bz2/from/this/mirror -o php-5.2.4.tar.bz2
-
bunzip2 php-5.2.4.tar.bz2
-
tar -xf php-5.2.4.tar
-
cd php-5.2.4
-
Then paste the configure line and add '--with-gd' to the end of it. Press return and watch it go.
If at any point it doesn't finish successfully, post back and we'll help you out.
Next execute 'make', then 'make test'. Follow the prompts.
If not too many of the tests fail, execute the following commands: -
apachectl stop
-
make install
-
apachectl start
-
If you have any q's or c's post back, and we'll help you out.

Thanks, I am trying this now. I have resest the password and have to wait an hour.
Is there another way to do or does it have to be done via ssh?
Cheers
