By default, emails sent from your wordpress blog will display from WordPress . Luckily, there is a very simple fix for this:

Add the following snipit of code to your functions.php file in your wordpress theme.


function res_fromemail($email) {
$wpfrom = get_option('admin_email');
return $wpfrom;
}

add_filter('wp_mail_from', 'res_fromemail');
add_filter('wp_mail_from_name', 'res_fromname');

This is sweet little helper… and if you’ve ever wanted to be able to automatically create a custom field with a value when a post (or page) is created, this little snippet of WordPRess code is for you.

It is to be added to your Functions.php file within your theme. Simply change the “field-name” and “custom value” to make it work.

add_action('publish_page', 'add_custom_field_automatically');
add_action('publish_post', 'add_custom_field_automatically');
function add_custom_field_automatically($post_ID) {
global $wpdb;
if(!wp_is_post_revision($post_ID)) {
add_post_meta($post_ID, 'field-name', 'custom value', true);
}
}

I discovered this little post by Alex Whinfield that just made me so happy.  I just know that it will make you happy too. It’s a “Seconds Ago” counter that uses the $UNIXTIMESTAMP php call to calculate a time since.  Works great and is very light. Get the code here.

I recently had a need where content needed to be included in a certain blog category and not in others. The content will only display post is in the specified category. You can use the category slug or the category ID.

<?php if (in_category('1')); ?>
<div class='someclass'>
<p>Some Content</p>
</div>
<?php endif; ?>
