[SOLVED] help needed making this thumbnail creating code work.

[thyscorpion]

Hi ,

I got this code from a tutorial.. and it is not working on my php 5 server.

according to me it stops working after this line. ( nothing i echo after it comes on teh screen.)..

 

			      $img = imagecreatefromjpeg( $pathToImages.$philename );
      echo "done so far... ";

i am confused as to what could be the problem. am i using the imagecreatefromjpeg( ); wrongly?

Please Advise...

 

Thanks

is GD support compiled into your PHP installation? check phpinfo() to find out.

 

also, if GD support is not compiled in, PHP should complain about an undefined function. If that's the error and you're not seeing it, you should be. Your errors may be turned completely off in php.ini.

YEs you were right. i switched on the errors and i got this:

 

"Fatal error: Call to undefined function imagecreatefromjpeg() in D:\www\ankur\upload2existingalbum.php on line 47"

 

how do i install GD support to my PHP installation?

[BlueSkyIS]

you must compile GD into a new PHP installation. are you on windows or non-windows?

[thyscorpion]

I have my php on both fedora and on windows xp pro... but i am using windows currently.

 

[thyscorpion]

oh am using PHP 5 with Apache 2_2 :-)

[BlueSkyIS]

Sorry, I don't know anything about compiling PHP on Windows. Linux is pretty straightforward via command line or especially easy via WHM/CPanel. For OS X there's MAMP where everything is precompiled and almost too simple, if that's possible...

[thyscorpion]

No problem.. will google it! :-)

[corbin]

Assuming you have the entire (well... standard) php stuff, you should just have to uncomment a line in php.ini.

 

;extension=php_gd2.dll

 

extension=php_gd2.dll

 

 

You have to have php_gd2.dll in your extensions directory though ;p (or your path setting).
