This might just do the trick.
I have tested the code myself and it seems to be working the way you requested. The script will list files and sub-folders in the folder you define; either directly in the script or by $_GET data. It should return data like this:
Code:
* img/ipsum
o landscape_0.png
+ type: landscape
o panoramic_2.png
+ type: panorama
o portrait_1.png
+ type: portrait
* img/landscape_0.png
* img/lorem
o ipsum
+ no type found!
o landscape_0.png
+ type: landscape
o panoramic_2.png
+ type: panorama
o portrait_1.png
+ type: portrait
You should note that it will probably fail on image names that contains numbers and all kinds of symbols except a-z. To make it possible to use numbers in your image names, I recommend using this format:
1_panorama34.jpg - <image type>_<image name>
Here we go:
PHP Code:
<?php
/**
* Set the directory to be scanned
*
* If $_GET['dir'] is present, use that
* Otherwise use 'img'
**/
$directory = isset( $_GET['dir'] ) ? $_GET['dir'] : 'img';
// Array containing 'bad' files, such as system and hidden files
$bad_files = array( '.', '..', '.DS_Store', '_notes', 'Thumbs.db' );
echo '<h1>Scan folder for sub-folders containing images</h1>
<p>Scanned folder: <strong>' . $directory . '</strong></p>
<h2>Result:</h2>';
// Make sure the filename we are checking is a directory
if( is_dir( $directory ) )
{
// Scan the directory for sub-directories and files
$content = scandir( $directory );
// Compare content array against bad files array to remove bad files
$files = array_diff( $content, $bad_files );
// Process files in the directory
foreach( $files as $key => $value )
{
echo '<ul><li>' . $directory . '/' . $value . '</li>';
// Check if the file is a sub-directory
if( is_dir( 'img/' . $value ) )
{
echo '<ul>'; // Sub-directory content lists
// Scan the sub-directory
$new_content = scandir( 'img/' . $value );
// Compare new content array against bad files array to remove bad files
$new_files = array_diff( $new_content, $bad_files );
// Process files in the sub-directory
foreach( $new_files as $key => $value )
{
echo '<li>' . $value . '</li><ul>'; // File name and beginning of image type list
/**
* Get image type according to number in file name (<filename>_<number>)
*
* $matches[0] returns the whole file name including number
* $matches[1] returns only the name (before _)
* $matches[2] returns only the number (after _)
*
* Returns 3 if no number is found
**/
$image_type = preg_match( '/([a-z]+)_(\d+)/i', $value, $matches ) ? $matches[2] : 3;
/**
* Display image type based on $image_type
*
* If image_type is 3 (or anything except 0-2), error message is displayed
* Remove default to ignore the error message
**/
switch( $image_type )
{
case 0:
echo '<li>type: <strong>landscape</strong></li>';
break;
case 1:
echo '<li>type: <strong>portrait</strong></li>';
break;
case 2:
echo '<li>type: <strong>panorama</strong></li>';
break;
default:
echo '<li><strong>no type found!</strong></li>';
break;
}
echo '</ul>'; // Image type list
}
echo '</ul>'; // Sub-directory content lists
}
echo '</ul>'; // Main directory lists
}
}
?>
If you experience any kind of problems, please let me know.
