Jean-Baptiste Jung — Mon, 06 Sep 2010 06:34:14 +0000

function wpprogrammer_post_name_in_body_class( $classes ){
	if( is_singular() )
	{
		global $post;
		array_push( $classes, "{$post->post_type}-{$post->post_name}" );
	}
	return $classes;
}

add_filter( 'body_class', 'wpprogrammer_post_name_in_body_class' );

Jean-Baptiste Jung — Tue, 31 Aug 2010 11:43:23 +0000

Just paste the code below into your functions.php file. If you prefer to use a plugin with the same functionality, you can grab one here.

// This will occur when the comment is posted function plc_comment_post( $incoming_comment ) { // convert everything in a comment to display literally $incoming_comment['comment_content'] = htmlspecialchars($incoming_comment['comment_content']); // the one exception is single quotes, which cannot be #039; because WordPress marks it as spam $incoming_comment['comment_content'] = str_replace( "'", ''', $incoming_comment['comment_content'] ); return( $incoming_comment ); } // This will occur before a comment is displayed function plc_comment_display( $comment_to_display ) { // Put the single quotes back in $comment_to_display = str_replace( ''', "'", $comment_to_display ); return $comment_to_display; } add_filter( 'preprocess_comment', 'plc_comment_post', '', 1); add_filter( 'comment_text', 'plc_comment_display', '', 1); add_filter( 'comment_text_rss', 'plc_comment_display', '', 1); add_filter( 'comment_excerpt', 'plc_comment_display', '', 1);

As usual, let's start by pasting the function in your functions.php file:

function get_category_id($cat_name){ $term = get_term_by('name', $cat_name, 'category'); return $term->term_id; }

Once you saved the file, just call the function with your category name as a parameter. Example:

function get_average_readers($feed_id,$interval = 7){ $today = date('Y-m-d', strtotime("now")); $ago = date('Y-m-d', strtotime("-".$interval." days")); $feed_url="https://feedburner.google.com/api/awareness/1.0/GetFeedData?uri=".$feed_id."&dates=".$ago.",".$today; $ch = curl_init(); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_URL, $feed_url); $data = curl_exec($ch); curl_close($ch); $xml = new SimpleXMLElement($data); $fb = $xml->feed->entry['circulation']; $nb = 0; foreach($xml->feed->children() as $circ){ $nb += $circ['circulation']; } return round($nb/$interval); }

Add categories or tags to post programatically

Jean-Baptiste Jung — Mon, 19 Jul 2010 06:57:01 +0000

The first thing to do is to create an array of categories id. Once done, you simply have to use the wp_set_object() function, which take 3 parameters: The post id, an array of categories to add to the post, and the taxonomy type (category in this example).

$category_ids = array(4, 5, 6); wp_set_object_terms( $post_id, $category_ids, 'category');

Adding tags to a post is extremely easy as well. The only difference with the code to add categories is the taxonomy "post_tag" instead of "category".

$tag_ids = array(7, 8, 9); wp_set_object_terms( $post_id, $tag_ids, 'post_tag');
