delete_post_link()

I have created a function called ”Delete Post Link”. If you are logged in you will see a link which allows you to delete the current page or post, even without visiting admin.

get_content() WITH formatting

2010-01-16 @ 14:55

Normally the get_the_content() tag returns the content WITHOUT formatting. I found out a solution in Wordpress core to make get_the_content() tag return the same content as the_content().

    Agree with Rama. Even get_by_postname would work...good for anti-collision in a plugin.

get_permalink_by_name()

I created a function that returns an URL when sending a post / page name as an in parameter. Put the function into your functions.php in your theme folder.

    This is my approach for the same problem

    function get_permalink_by_title($title){
    $page = get_page_by_title($title);
    $pageID = $page->ID;
    $permalink = get_permalink($pageID);

get_user()

2010-01-16 @ 14:51

Wordpress have a built in function called get_currentuserinfo. A global variable is set. It calls a function to get the user information. It then echos the username. The code is not as short and easy as it could be.

Wordpress have a ”bug”. It doesn’t add a current_cat_ancestor class to the wp_list_pages function. If you need it, you can use the code below.

Get ID by post or page name

2010-01-16 @ 14:33

What I don’t like with wp_list_pages is that you can’t exclude or include pages by NAME. Only by ID is available. Here is the solution.
