Field Key	Unique identifier. Lowercase letters and underscores only.
Label	Display label shown above the field.
Description	Optional helper text shown below the field.
Placeholder	Optional placeholder, e.g. `https://example.com`
Default Value	Optional default URL.

Return Value

Returns a string containing the URL. Returns an empty string if no value is saved.

Usage

php

// Get the value
$url = onemeta_get_meta( get_the_ID(), 'field_key' );

// Display as a link
if ( ! empty( $url ) ) {
    echo '<a href="' . esc_url( $url ) . '" target="_blank" rel="noopener noreferrer">';
    echo esc_html( $url );
    echo '</a>';
}

Template Example

php

<?php $website = onemeta_get_meta( get_the_ID(), 'website_url' ); ?>

<?php if ( ! empty( $website ) ) : ?>
    <a href="<?php echo esc_url( $website ); ?>"
       target="_blank"
       rel="noopener noreferrer"
       class="btn btn-outline">
        Visit Website
    </a>
<?php endif; ?>

Notes

Always use esc_url() when outputting URL values in HTML — never echo raw
Add rel="noopener noreferrer" on external links that open in a new tab
