Dear all,
Actually, this function could be used as is. To avoid automatic appending to post content, comment out the line:
add_filter('the_content', 'wpatt_content_filter');
Once you’ve done this, all that’s left to do is to make a call to the function: wpatt_content_filter
I’ve commented out the line as before and added a separate function based on the code to my functions.php. It looks like this:
function show_attachments($content) {
global $post;
$somethingtoshow = 0;
$content_l = null;
$checkrestrict = false;
if ( get_option('wpatt_option_restrictload') && !is_single() && !is_page() ) { $checkrestrict = true; }
if ($post->ID == '0' || $post->ID == NULL || get_post_meta($post->ID, 'wpa_off', true) || post_password_required() || $checkrestrict ) { return $content; }
$attachments = get_posts(array(
'post_type' => 'attachment',
'orderby' => 'menu_order',
'order' => 'ASC',
'posts_per_page' => 100,
'post_parent' => $post->ID
));
if ($attachments) {
$content_l .= '<!-- WP Attachments --><ul class="post-attachments">';
foreach ($attachments as $attachment) {
$wpatt_option_includeimages_get = get_option('wpatt_option_includeimages');
if ($wpatt_option_includeimages_get == '1') {
} else if ( wp_attachment_is_image( $attachment->ID ) ) {
continue;
}
$somethingtoshow = 1;
$class = "post-attachment mime-" . sanitize_title($attachment->post_mime_type);
if ($wpatt_option_targetblank_get == '1') { $content_l .= 'target="_blank" '; }
if ((file_exists(get_attached_file($attachment->ID)))) {
$wpatt_fs = wpatt_format_bytes(filesize(get_attached_file($attachment->ID)));
} else {
$wpatt_fs = 'ERROR';
}
$wpatt_date = new DateTime($attachment->post_date);
switch ( get_option('wpa_template') ) {
case 1: //STANDARD WITH DATE
$wpattachments_string = '<a href="%URL%">%TITLE%</a> <small>(%SIZE%)</small> <div style="float:right;">%DATE%</div>';
break;
case 2: //EXTENDED
$wpattachments_string = '<a href="%URL%">%TITLE%</a> <small>• %SIZE% • %DOWNLOADS% click</small> <div style="float:right;">%DATE%</div><br><small>%CAPTION%</small>';
break;
case 3: //CUSTOM
$wpattachments_string = html_entity_decode( get_option('wpa_template_custom') );
break;
default: //DEFAULT
$wpattachments_string = '<a href="%URL%">%TITLE%</a> <small>(%SIZE%)</small>';
}
if ( get_option('wpatt_option_targetblank') ) {
$wpattachments_string = str_replace('<a href', '<a target="_blank" href', $wpattachments_string);
}
if ( get_option('wpatt_counter') ) {
$url = add_query_arg( 'download', $attachment->ID, get_permalink() );
} else {
$url = wp_get_attachment_url($attachment->ID);
}
$wpattachments_string = str_replace("%URL%", $url, $wpattachments_string);
$wpattachments_string = str_replace("%TITLE%", $attachment->post_title, $wpattachments_string);
$wpattachments_string = str_replace("%SIZE%", $wpatt_fs, $wpattachments_string);
$wpattachments_string = str_replace("%DATE%", $wpatt_date->format(get_option('wpatt_option_date_localization')), $wpattachments_string);
$wpattachments_string = str_replace("%CAPTION%", $attachment->post_excerpt, $wpattachments_string);
$wpattachments_string = str_replace("%DESCRIPTION%", $attachment->post_content, $wpattachments_string);
$wpattachments_string = str_replace("%AUTHOR%", get_the_author_meta( 'display_name', $attachment->post_author), $wpattachments_string);
$wpattachments_string = str_replace("%DOWNLOADS%", wpa_get_downloads($attachment->ID), $wpattachments_string);
$content_l .= '<li class="' . $class . '">' . $wpattachments_string . '</li>';
}
$content_l .= '</ul>';
}
if ($somethingtoshow == 1) {
$content .= $content_l;
} else {
$content .= 'No downloads available!';
}
return $content;
}
Basically, it’s the same function as wpatt_content_filter, but I’ve added a couple of lines if no attachments are available:
if ($somethingtoshow == 1) {
$content .= $content_l;
} else {
$content .= 'No downloads available!';
}
The only risk is that these changes may be overwritten in case of a plugin update, but for the moment, these changes work well for me. Please note that I’m not checking whether the plugin is activated or any other checks; I’m doing these steps elsewhere in my theme, so you may want to check whether the function, wpatt_content_filter exists before using it, else you’ll see a white screen.
