phpThumb Image Resizing Errors

Question

I have spent all day on this and can't figure out where I'm going wrong.

I am trying to resize some images to then write them to a folder so they can be zipped up and downloaded.

I can get the images to resize, rename and then save into another directory when using the phpThumb Demo -> phpThumb.demo.object.php. This is because the source image, phpThumb class, and the final image destination directory are all in the same folder.

However, I have now changed the directory structure so the phpThumb.class.php file is being called from the admin subdomain and the images need to be grabbed from the images subdomain and then saved to a directory in either the images or admin domains so I can get them later to write to a ZIP file.

I am just getting errors all the time and can't make out where to go from here. Can anyone help?

Here is the php:

require_once('../phpThumb/phpthumb.class.php');

// create phpThumb object
$phpThumb = new phpThumb();

// create 3 sizes of thumbnail
$thumbnail_widths = array(160, 320, 1000);
$capture_raw_data = false; // set to true to insert to database rather than render to screen or file (see below)
foreach ($thumbnail_widths as $thumbnail_width) {

    // this is very important when using a single object to process multiple images
    $phpThumb->resetObject();

    // set data source -- do this first, any settings must be made AFTER this call
    $phpThumb->setSourceFilename('/home/server/domains/images.testdomain.co.uk/public_html/high-res/CM015585.jpg');

    // PLEASE NOTE:
    // You must set any relevant config settings here. The phpThumb
    // object mode does NOT pull any settings from phpThumb.config.php
    $phpThumb->setParameter('config_document_root', '/home/server/domains/images.testdomain.co.uk/public_html/');
    $phpThumb->setParameter('config_cache_directory', '/home/server/domains/images.testdomain.co.uk/public_html/phpThumb/cache/');      

    $phpThumb->setParameter('w', $thumbnail_width);

    // set options (see phpThumb.config.php)
    // here you must preface each option with "config_"
    $phpThumb->setParameter('config_output_format', 'jpg');
    $phpThumb->setParameter('config_imagemagick_path', '/usr/local/bin/convert');   

    // generate & output thumbnail
    $output_filename = 'zip_temp/_'.$thumbnail_width.'.'.$phpThumb->config_output_format;
    echo $output_filename;
    if ($phpThumb->GenerateThumbnail()) { // this line is VERY important, do not remove it!
        $output_size_x = ImageSX($phpThumb->gdimg_output);
        $output_size_y = ImageSY($phpThumb->gdimg_output);
        if ($output_filename || $capture_raw_data) {
            if ($capture_raw_data && $phpThumb->RenderOutput()) {
                // RenderOutput renders the thumbnail data to $phpThumb->outputImageData, not to a file or the browser
                //mysql_query("INSERT INTO `table` (`thumbnail`) VALUES ('".mysql_escape_string($phpThumb->outputImageData)."') WHERE (`id` = '".$id."')");
            } elseif ($phpThumb->RenderToFile($output_filename)) {
                // do something on success
                echo 'Successfully rendered:<br><img src="http://images.testdomain.co.uk/zip_temp/'.$output_filename.'">';
            } else {
                // do something with debug/error messages
                echo 'Failed (size='.$thumbnail_width.'):<pre>'.implode("\n\n", $phpThumb->debugmessages).'</pre>';
            }
            $phpThumb->purgeTempFiles();
        } else {
            $phpThumb->OutputThumbnail();
        }
    } else {
        // do something with debug/error messages
        echo 'Failed (size='.$thumbnail_width.').<br>';
        echo '<div style="background-color:#FFEEDD; font-weight: bold; padding: 10px;">'.$phpThumb->fatalerror.'</div>';
        echo '<form><textarea rows="10" cols="60" wrap="off">'.htmlentities(implode("\n* ", $phpThumb->debugmessages)).'</textarea></form><hr>';
    }

}

Answer 1

open file phpthumb/phpthumb.class.php and change line 141:

var $config_disable_debug = true;

to

var $config_disable_debug = false;

Revisit the original page, and this time the actual error message should appear
