Adding Extra Fields to the WordPress User Profile

c.bavota — Thu, 10 Dec 2009 17:23:54 +0000

By default WordPress offers some great options. Whenever a member joins, they have the ability to add more information about themselves, such as a Web site URL, a short bio and their AIM. You might require a bit more info from your members and creating extra fields in the user profile is pretty straightforward.

With the following code, you can add some extra fields asking your members for their address. Just add the code t your theme’s functions.php file, or create a functions.php file if you don’t already have one.


add_action( 'show_user_profile', 'extra_user_profile_fields' );
add_action( 'edit_user_profile', 'extra_user_profile_fields' );
 
function extra_user_profile_fields( $user ) { ?>
 _e("Extra profile information", "blank"); ?>
 


 _e("Address"); ?>

 echo esc_attr( get_the_author_meta( 'address', $user->ID ) ); ?>" class="regular-text" />

 _e("Please enter your address."); ?>



 _e("City"); ?>

 echo esc_attr( get_the_author_meta( 'city', $user->ID ) ); ?>" class="regular-text" />

 _e("Please enter your city."); ?>



 _e("Province"); ?>

 echo esc_attr( get_the_author_meta( 'province', $user->ID ) ); ?>" class="regular-text" />

 _e("Please enter your province."); ?>



 _e("Postal Code"); ?>

 echo esc_attr( get_the_author_meta( 'postalcode', $user->ID ) ); ?>" class="regular-text" />

 _e("Please enter your postal code."); ?>



 }
 
add_action( 'personal_options_update', 'save_extra_user_profile_fields' );
add_action( 'edit_user_profile_update', 'save_extra_user_profile_fields' );
 
function save_extra_user_profile_fields( $user_id ) {
 
if ( !current_user_can( 'edit_user', $user_id ) ) { return false; }
 
update_user_meta( $user_id, 'address', $_POST['address'] );
update_user_meta( $user_id, 'city', $_POST['city'] );
update_user_meta( $user_id, 'province', $_POST['province'] );
update_user_meta( $user_id, 'postalcode', $_POST['postalcode'] );
}
?>

Add Time to the Date Function in PHP

I just needed to do this for a client’s site to set an expiration date for a user and I thought it might be something that other programmers might like to know how to do. If you need to take today’s date and add time to it it is pretty simple. There is a PHP function called date() and another called strtotime(). You need to use both to make this happen.

$date = date('Y-m-d');
$timestamp = strtotime(date("Y-m-d", strtotime($date)) . " + 1 month");
$expired = date('Y-m-d', $timestamp);

If you echoed out $date you would get today’s date formatted like “2009-04-21″.

If you echoed out $expired you would get today’s date plus 1 month, formatted like “2009-05-21″.

You can replace the “1 month” with “14 days” or “2 years” or whichever increment you need.

Show Your Search Query in WordPress

Wouldn’t you like to be able to display the actual search term entered by your user on the search results’ page? Good thing there is a very simple way in WordPress to do that with the_search_query function. Just open up your search.php file and enter:

 the_search_query(); ?>

to display the search term that was entered. So something like this:

 echo 'Search Results for "'; the_search_query(); echo '"'; ?>

would display something that looked like this:

Search Results for “the search term”

Another cool little trick it to add the number of search results. Use this code:


$mySearch =& new WP_Query("s=$s & showposts=-1");
$num = $mySearch->post_count;
echo $num.' search results for "'; the_search_query();
?>

to display something like:

18 search results for “the search term”

Checking if a Widget has Been Activated in WordPress

c.bavota — Wed, 04 Feb 2009 19:05:23 +0000

Sometimes, it is extremely difficult to find out if a function already exists in WordPress or if you need to create one yourself to get it to function how you need it to. I had created a widget for my Magazine Basic 2.0 free premium theme and I needed to make sure that if it was added to a user’s sidebar, then certain functionality would occur.

I couldn’t find out how to do it so I decided to use PHP Sessions. The only problem with this is that WordPress doesn’t allow you to upload a theme to WordPress.org that uses Sessions. So I searched and searched and finally found what I need buried deep in the WordPress code. To check if a widget has been activated you need to use the following code.

is_active_widget('name_of_widget')

Replace name_of_widget with the original function name of your widget. If you were using my Features Post widget then the code to check if it is activated would be:

is_active_widget('widget_myFeature')

Issue with the User Logout Button in WordPress 2.7

c.bavota — Thu, 29 Jan 2009 18:19:53 +0000

I noticed a small issue in WordPress 2.7 when I was designing a login bar at the top of a client’s site and the logout link would not log the user out. I had coded the same way I had coded a logout button in the past, but it wouldn’t function properly. That is because WordPress 2.7 uses a new function to log a user out.

Here is the code I use to use:

 echo get_option('siteurl'); ?>/wp-login.php?action=logout">Logout

And here is the new code I now use:

 echo wp_logout_url() ?>">Logout

And here is a little bit of spice to make it redirect back to the current page:

 echo wp_logout_url(get_permalink()); ?>" >Logout

Nore: If you are using an theme that was designed before 2.7, you should go into your comments.php file and change the anchor tag around line 78 to fix your Logout link.
