Adding icons to attachment display
Last modified: August 23, 2009 - 21:12
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
