Keywords

Overview

Details about implementing keywords with PHP classes.

PHP libraries

• [COMMON_LIB]_classes/db/db_keyword_content_class.php
• [COMMON_LIB]_classes/keywords/keyword_class.php

Displaying keywords

Displaying keyword lists within listings pages

• LITTLED/JQuery config within $(document).ready()

$fn.keywords('bindListingsHandlers');

• This is not rolled into $fn.listings('bindListingsHandlers')
• Typically, it would be added to a JQuery plugin targeted to a specific CMS content section:

/*
 * file: content_type.js
 * JQuery added functionality
 */
(function($) {
	var methods = {
		bindListingsHandlers: function() {
			
			return this.each(function() {

				/* listings handlers */
				$(this)
				.listings('bindListingsHandlers')
				.keywords('bindListingsHandlers');

				LITTLED.init({setSortables: function() {
					$('#listings-container')
					.listings('bindListingsButtons')
					.keywords('bindListingsButtons');
				}});
			});
		},
/* etc... */

• Outside the listings loop,

• Define an object to use to retrieve and display keyword lists.
• Set the keyword object's content id to the appropriate value for the listings content.

• Within the listings loop,

• Set the id of the keyword object to the current record id.
• Include shared content include to display keyword list.
• Clear keyword values.

$keywords = new db_keyword_content_class($filters->site_section->id->value);
while ($row = mysql_fetch_object($rs)) {
?>
	<tr class="rec-row <?=$rowClass?>" id="rr-<?$filters->site_section->id->value?>-<?=$row->id?>" data-rid="<?=$row->id?>">
		<td>
<?
	$keywords->id->value = $row->id;
	include (COMMON_TEMPLATE_DIR."content/keywords/keywords_cell.php");
	$keywords->clear_keyword_data();
?>
		</td>
	</tr>
}

Displaying keyword lists within 'details' pages

• TK

Album keyword filter autocomplete

• AJAX handler: /_ajax/images/album_title_search.php
• Define derived version of search_titles(). The base routine album_filters_class->search_titles() routine won’t work with the table structure.
