Get posts with custom field & specific value - WordPress

The custom field is an amazing option in WordPress blog engine. We can make hundreds of useful applications & tricks with custom field to improve functionality of WordPress.

Today we are going to use this custom field in a creative way. We try to output a list of posts with a specific custom field and specific value through a simple hack.

I already say that this is too simple. We just want to add some new parameters with loop used to query posts.

<?php query_posts('meta_key=review_type&meta_value=movie');  ?>
<?php if (have_posts()) : ?>
<?php while (have_posts()) : the_post(); ?>

To get posts with a specific custom field and specific value, we use the query_posts() function with the meta_key and meta_value parameters. The meta_key value is the name of the desired custom field, and meta_value is the desired value.
