Message if no items are returns

    Hi Paul,
    I’m really finding your plugin very useful.

    I’m using it to pull a list of information leaflets based on what they’re tagged and display them using display_item_callback in my functions.php

    The leaflets are tagged with ‘expired’ or ‘not-expired’ and won’t display if leaflet is missing the ‘not-expired’ tag. I have 50 odd pages that display leaflets based on the department or specialty and sometimes the leaflets expire before they are renewed.

    The only thing I haven’t been able to figure out is how to display a message if no leaflets are returned. I’m not experienced enough in php to know how to add a check in my functions.php

    I have

    function pdfs_mediatags($post_item)
{
$media_src = wp_get_attachment_url($post_item->ID);
return '<tr><td><a href="'.$media_src.'" title="'.$post_item->post_title.' class="media-tag-list clearfix" id="media-tag-item-'.$post_item->ID.'">'.$post_item->post_title.'</a></td><td>'.mysql2date("j M Y", $post_item->post_date).'</td></tr>';

    I know this isn’t good practice, but I managed to edit your mediatags_shortcodes.php file like so, which gives me what I need, but obviously as you update your plugin, I’ll need to keep a track of this

    function mediatags_shortcode_handler($atts, $content=null, $tableid=null)
{
	global $mediatags;

	if ((!isset($atts['return_type'])) || ($atts['return_type'] != "li"))
		$atts['return_type'] = "li";

	if (!isset($atts['after_list'])) {
		if (isset($atts['before_list'])) {
			if ($atts['before_list'] == "ul")
				$atts['after_list'] = "</ul>";
			else if ($atts['before_list'] == "ol")
				$atts['after_list'] = "</ol>";
		} else {
			$atts['after_list'] = "</ul>";
		}
	}

	if (!isset($atts['before_list'])) {
		$atts['before_list'] = "<ul>";
	}

	if (!isset($atts['error_message'])) {
		$atts['error_message'] = "";
	}

	if ((!isset($atts['display_item_callback'])) || (strlen($atts['display_item_callback']) == 0))
		$atts['display_item_callback'] = 'default_item_callback';

//	if (isset($atts['post_parent'])) {
//		if (($atts['post_parent'] == "this") || ($atts['post_parent'] == "self")) {
//			$atts['post_parent'] = $post->ID;
//		}
//	}
	$atts['call_source'] = "shortcode";

	//echo "atts<pre>"; print_r($atts); echo "</pre>";

	if (!is_object($mediatags))
		$mediatags = new MediaTags();

	$output = $mediatags->get_attachments_by_media_tags($atts);
	if ($output)
	{
		if (isset($atts['before_list']))
		{
			$output = $atts['before_list'] . $output;
		}

		if (isset($atts['after_list']))
		{
			$output = $output .$atts['after_list'];
		}
	}
	else {
		$output = $output .$atts['error_message'];
	}
	return $output;

}

    Is there a way of doing this with hacking your code?

    Many thanks

    @huskypup,

    I agree the plugin probably needs to handle some ‘items not found logic’. My guess it you are using the shortcode meths, correct? In that case there it not a way within the shortcode to handle the case.

    Thanks for the reply Paul.

    Yes, I had to add extra code to your mediatags_shortcodes.php and add an extra option of ‘error_message’ to the shortcode.

    Do you think this is something you’ll factor in future versions?

    @huskypup,

    Yes, That is my thought. Will look at adding similar logic into the next release. Thanks.
