Question

I am writing a wordpress plugin and I want to hide posts/pages which contain a specific string in their title.

For example, I want to hide all the posts/pages where the title contains: [something123]

show this post/page “Lorem Ipsum”
hide this post/page “Lorem Ipsum [something123]”
hide this post/page “Hello World [something123]”
show this post/page “Hello World”

Answer 1

In your theme directory find loop.php

In it there should be a line like this

<?php while ( have_posts() ) : the_post(); ?>

pseudocode:

if (get_the_title() contains "") { endwhile; }

You could also use a filter:

Although I don’t feel like writing one for you =). Maybe somebody else will.
