A few tidbits for WordPress I picked up this week working on Psychic Coupons and a couple other sites.

===============================================

This is an oldie but goody, helps a lot: http://codex.wordpress.org/Template_Hierarchy

===============================================

Here’s one from equalmark and banago at http://wordpress.org/support/topic/query-if-on-front-page-home-index :
If you’re on the front page, conditional statements:

<?php if(is_front_page() ) { ?> //do stuff <?php } ?>
— or --
<?php if(is_home() ) { //do stuff } else { //do stuff } ?>

Mvied notes: I’d just like to point out that the is_home() function is true if you’re on the main blog page, and the is_front_page() function can be the same page unless you have a static front page set, then it will only be true on that page.

============================================

Passing variables in the URL, by stvwlf from http://wordpress.org/support/topic/passing-variables-using-the-permalink-structure :

Step 1:
Create and save PHP file in plugins directory:
<?php
/* Plugin Name: Parameter
Plugin URI: http://webopius.com/
Description: A plugin to allow parameters to be passed in the URL and recognized by WordPress
Author: Adam Boyse
Version: 1.0
Author URI: http://www.webopius.com/
*/
add_filter('query_vars', 'parameter_queryvars' );

function parameter_queryvars( $qvars )
{
$qvars[] = ' myvar';
return $qvars;
}
?>

Step 2:
Pass var in URL href:
if (isset($wp_query->query_vars['myvar']))
{
print $wp_query->query_vars['myvar'];
}
