by in , 0

You'll need to be able to run SQL on that database, like for example, through phpMyAdmin.

UPDATE `wp_users` SET `user_pass` = MD5( 'new_password_here' ) WHERE `wp_users`.`user_login` = "admin_username";

wordpress Reset Admin Password in Database

by in , 0

Forget your admin password and don't have access to the email account it's under? If you can get access to phpMyAdmin (or anything you can run mySQL commands), you can update it there.

UPDATE `wp_users` SET `user_pass` = MD5( 'new_password_here' ) WHERE `wp_users`.`user_login` = "admin_username";

Just replace new_password_here with the new password and admin_username with the real admin accounts usename.

wordpress Remove Whitespace from Function Output

by in , 0

In WordPress, there are many functions which output things for you. For example, wp_list_pages() outputs a list of all your published pages. The HTML markup it spits out is pretty nicely formatted (meaning: has line breaks and indenting).

There are some circumstances where all that "whitespace" in the formatting is undesirable. Like 1) it's all the more characters to deliver and 2) closing "the gap" in older versions of IE.

If the function supports a way to return a string (rather than immediately echo it), you can use a regex to remove the space:

<?php
   echo preg_replace('/>\s+</m', '><', wp_list_pages('echo=0'));
?>
