Using a custom field instead of using "Featured image"

    Hi all.

    I have created a new instance of one of my blogs as I want to try out a new theme. I have, however, a common directory where I put images, namely the featured images to use in posts.

    Problem is: in my old theme I would control the use of the featured image using a specific “image” custom field within each post. In the new theme, I need to manually define it using a “Featured image” box, while in post edit, on the right sidebar. Once I’m done doing this, the image actually appears here.

    My problem is that I have hundreds of posts and so I’d like to find a way of “telling” my theme from which custom field to fetch the images from. And I want to make use of the hundreds of featured images I already have as well.

    Any hints?

    Many thanks in advance.
    Antonio

    You’ll need to edit your theme, specifically the main loop that outputs your posts. You’ll need to change it from using a featured image to getting your image from a custom field. You can find some information on how to do that here.

    Example of the conditional statement for a loop.

    $values = get_post_custom_values("image"); // check before if post has the custom field
if (isset($values[0])) {
    echo '<a href="'.get_permalink().'" ><img src="'.$values[0].'" alt="'.get_the_title().'" width="150" height="150" /></a>';
} elseif (has_post_thumbnail()) {
    echo '<a href="'.get_permalink().'" >';
    the_post_thumbnail(array(150,150), array('alt' => get_the_title(), 'title' => get_the_title()));
    echo '</a>';
}
