我如何让我的自定义字段仅在其中写入了某些内容时才显示-Wordpress？

Question

Im working on customizing a Wordpress theme with some custom fields. For this I'm using the plugin "Advanced Custom Fields", but I want it to display these fields ONLY IF something is written in them. This is the code I'm using to display the custom fields:

<p class="tittelboks">Artikkelforfatter:</p>
        <?php if( get_field('artikkelforfatter') )
        {
        echo '<p>' . get_field('artikkelforfatter') . '</p>';
        } ?>

How do I change the code so that it only echos the information AND the label (in this case .tittelboks) if something is written in the meta boxes?

Answer 1

<?php if( $field = get_field('artikkelforfatter') ): ?>
    <p class="tittelboks">Artikkelforfatter:</p>
    <p><?php echo $field; ?></p>
<?php endif; ?>

This is a different way of doing an if statement, so you don't have to enclose your HTML in quotes and worry about escaping. The two lines in the middle will only print out if get_field('artikkelforfatter') returns a value or true. That value will be assigned to the $field variable.

Answer 2

Something like this should work:

<?php
$artikkel = get_field( 'artikkelforfatter' );

if ( ! empty( $artikkel ) ) {
?>
<p class="tittelboks">Artikkelforfatter:</p>
<p><?php echo $artikkel; ?></p>
<?php
}
?>

Answer 3

To use and display custom fields need you may try to put this in your loop.

<?php $what_name_you_want=get_post_meta($post->ID,'Your Custom Field Name',true); ?>

    <?php echo $what_name_you_want; ?>// This call the value of custom field

Only replace

what_name_you_want with your favorite name

and

Your Custom Field Name with the name of custom field

If the value of custom field is empty the echo will be empty to.

Tell me if it's work
