Question

In my theme I have custom field ‘ext_url’. Now I want to get post url If I don’t add ‘ext_url’ custom field.

I tried

<?php if(get_post_meta($post->ID, 'ext_url', true)): ?>
<?php else : ?>
<?php the_permalink(); ?>
<?php endif; ?>

When I don’t add custom field, it is showing post URL. But, when I add custom field it is showing blank. Any Solutions?

Update: I’ve found a code

<?php 
    $url = get_post_meta($post->ID, 'ext_url', true); 

    if ($url) {
        echo "<p><a href='$url'>External URL</a></p>";
    }
?>

but, it is working for showing custom field. How can i add else function here? Sorry, I am not experienced in PHP.

If you want it to display the data from the custom field, you should add a line to echo the results.

<?php
$ext_url = get_post_meta( $post->ID, 'ext_url', true );

if ( $ext_url ) {
    echo $ext_url;
} else {
    the_permalink();
}
?>
