Wordpress高级自定义字段 - 显示在PAGE模板上

Question

I am using Advanced Custom Fields with Wordpress. I have set up a field and can display it on my homepage/front-page.php template like this...

<?php the_field('primary_tagline'); ?>

I want to use the same field on my page.php template, but when i drop in the same code, no results are returned. I don't understand why it works on one template but not the other. Do i need different code to show the same field results across multiple templates? Here is the code...

   <?php the_field('primary_tagline'); ?>

    <div id="primary" class="content-area">
        <main id="main" class="site-main">
            <?php while ( have_posts() ) : the_post(); ?>
                <?php get_template_part( 'template-parts/content', 'page' ); ?>
                <?php
                    if ( comments_open() || get_comments_number() ) :
                        comments_template();
                    endif;
                ?>
            <?php endwhile; ?>
        </main><!-- #main -->
    </div><!-- #primary -->

Is it a loop problem? ACF won't show outside a loop?

Answer 1

If you want to grab field value outside the loop you must provide post_id as second parameter to the function

the_field($field_name, $post_id); //prints value
$value = get_field( $field_name, $post_id ); //returns value

ACF - get_field()

ACF - the_field()
