Wordpress: problem in loop

Question

So I have the following code:

    <?php
    query_posts("order=ASC&cat=4");
?>              
<?php if(have_posts()): while(have_posts()): the_post(); ?>
    <?php if(get_post_custom_values("show") != NULL): ?>
    <?php
        $categories = get_cat_ID(get_the_title());
        $url = get_category_link($categories);
    ?>
    <li class="thumb">
        <a href=""><?php the_post_thumbnail(array(215,200)); ?></a>
        <h2><a href=""><?php the_title(); ?></a></h2>
    </li>
    <?php endif; ?>
<?php endwhile; endif; ?>   
</ul>

This code works, but when you have & - in your title $categories = get_cat_ID(get_the_title()); .. get_cat_ID won't work, do you know a work around?

One thing I can see right off the bat is that you don't need the if(have_posts()) there... — Jacob Relkin

Try get_category_by_slug instead. Fetching the ID by the name of the category will get messy, especially with duplicates and characters, as you've discovered.

Doesn't it doesn't return the id for the first item, $categories = get_category_by_slug(get_the_title());

Do you know another method? :-s

What are you trying to do exactly? Get the ID of a specific category? The ID of the post's category (or categories)?

I'm trying to list a bunch of posts(products) from a category, and each post has a category, let's say if I have a post with the name of "Darling" that post is posted in a category called "darling" and I'm trying to list those posts, but link them with the link of the catory which is posted in, I hope you get what I said :( 'cause I need to get this working, It works but doesn't work for the posts with - & in it you can see an example here: is.gd/6hBgbd , It works for the Section Vitrinen but the links won't work for Braut if you click on the images you will see

For Vitrinen I duplicated the same code, and It works, because of the titles
