Chapetr 7- check_image.php

alextalamonti · March 15th, 2011, 04:21 AM

Hi, I'm testing the check_image.php script.
When I push Preview button, after setting the filters, I don't see the preview image...

. I always see the placeholder image. It seems that

Code:

$imagename = 'image_effect.php?id=' . $image_id  . '&e=' .
           $_POST['effect'];

Or

Code:

<img src="<?php echo $imagename; ?>" style="float:left;">

doesn't work. I don't know how can I do. My php version is 4.4
P.S. $dir is the same for check_image.php and image_effect.php

Ok! I resolved it myself.

I installed PHP 5.2!

Did you change the code? I cant make it to work with PHP 5.2!

I think I got the answer, in image_effect.php at the bottom of the code:

PHP Code:


			
// show the image
header('Content-Type: image/jpeg');
imagejpeg($image, '', 100);
?>

Should be:

PHP Code:


			
// show the image
header('Content-Type: image/jpeg');
imagejpeg($image, NULL, 100);
?>

Because we can't leave this second parameter filename as '' instead use NULL and try again uploading an image.

Hope it works :)
