Basically what I am trying to achieve is to have title changed of posts which are in category number 30.
My code is:
function adddd($title) {
if(has_category('30',$post->ID)){
$title = 'Prefix '.$title;
}
return $title;
}
add_action('the_title','adddd');
The code works, but has one issue. When I am inside the post which has that category, title is being changed for all other pages (which are called through the_title) too.
How can I change the title only to post titles which has that category, no matter what page I am on?

Reset to default 1$post is undefined in your filter. You need to explicitely invoke the $post global inside your filter function to have it available. You must remember that variables (even global variables) outside a function will not be available inside a function, that is how PHP works.
You actually do not need to use the $post global, the post ID is passed by reference as second parameter to the the_title filter.
You can use the following:
add_action( 'the_title', 'adddd', 10, 2 );
function adddd( $title, $post_id )
{
if( has_category( 30, $post_id ) ) {
$title = 'Prefix ' . $title;
}
return $title;
}
If you need to target only the titles of posts in the main query/loop, you can wrap your contional in an extra in_the_loop() condition
Why not use javascript/jquery?
if your use <?php post_class(); ?> you can find a different class for each category.
$('.post.category-one').find('h2.item-title').prepend('Prefix ');
Use .find() to the selector title
Edit
With php try this
function adddd($title) {
global $post;
if(has_category('30',$post->ID)) {
$title = 'Prefix '.$post->post_title;
}
return $title;
}
add_action('the_title','adddd');
