Override the display of attachment /Add icons
Overriding the display of attachments -> Adding icons
Tested on Drupal 4.7
This override will add a column of icons corresponding to the the file attached. Hence, the file types (i.e. image, pdf) are more visible to the viewer.
First:
- Create an 'icons' directory in default 'files' directory.
- All icons should be of the same type, i.e. (png, gif)
- Name the icons according to MIME types & sub-types as follows.
- For image as a type, name the icon -> 'image'.[png|gif]
- For text as a type, name the icon-> text.[png|gif]
- For application as a type, name the icon -> sub-type.[png|gif]
- Example of icons directory listing
default.gif
image.gif
msword.gif
pdf.gif
rtf.gif
text.gif
vnd.ms-excel.gif
vnd.ms-powerpoint.gif
zip.gif
Note mime types look like this [image/jpeg] -> [type/sub-type]
Secondly:
Create template.php in desired theme directory with following code or if one exist append the following code
<?php
/**
* Overide the default theming for attachments
*/
function phptemplate_upload_attachments($files) {
$header = array('',t('Attachment'), t('Size'));
$rows = array();
foreach ($files as $file) {
if ($file->list) {
$href = check_url(($file->fid ? file_create_url($file->filepath) : url(file_create_filename($file->filename, file_create_path()))));
$text = check_plain($file->description ? $file->description : $file->filename);
$rows[] = array(theme('file_icon', $file) ,l($text, $href), format_size($file->filesize));
}
}
if (count($rows)) {
return theme('table', $header, $rows, array('id' => 'attachments'));
}
}
/**
* Theme file icon according to mime type
* an 'icons' directory should be placed inside your default files direcotry
* containing the file icons. Icon names should follow their Mime sub-type.
* Apart from the two generic types 'image' & 'text'
*
* @param file drupal file object
* @return HTML themed icon
*/
function phptemplate_file_icon($file) {
//Check if directory icons in current theme exists otherwise, no point, right
$icon_ext = '.gif'; //Change your supported format png for example
$path = file_directory_path().'/icons';
if( !is_dir($path) ) {
return;
}
//Get filemime type act accordingly
$mime = explode('/', $file->filemime);
$type = $mime[0];
$sub_type = $mime[1];
$output = '';
$defult_icn = $path.'/default'.$icon_ext;
switch($type) {
case 'image':
$img_path = $path.'/image'.$icon_ext;
if( is_file($img_path) ){
$output .= theme_image($img_path, $file->filename, $file->description);
}
else if( is_file($defult_icn) ) {
$output .= theme_image($defult_icn, $file->filename, $file->description);
}
break;
case 'text':
$txt_path = $path.'/text'.$icon_ext;
if( is_file($txt_path) ){
$output .= theme_image($txt_path, $file->filename, $file->description);
}
else if( is_file($defult_icn) ) {
$output .= theme_image($defult_icn, $file->filename, $file->description);
}
break;
case 'application':
$app_path = $path.'/'.$sub_type.$icon_ext;
if( is_file($app_path) ){
$output .= theme_image($app_path, $file->filename, $file->description);
}
else if( is_file($defult_icn) ) {
$output .= theme_image($defult_icn, $file->filename, $file->description);
}
break;
default:
if( is_file($defult_icn) ) {
$output .= theme_image($defult_icn, $file->filename, $file->description);
}
break;
}
return $output;
}
?>Change the $icon_ext variable to desired extension

Thanks seems to work pretty
Seems to work pretty good. Note the comments in the code for more info on setup. One thing though, It does not seem to work in IE 6 or 7. No icons show up, hmmm.
Thanks!
