用条件限制foreach循环

Question

this question already asked many times but I am unable to find a solution for my problem. My php knowledge is very limited.

I am building a wordpress website where there a custom taxonomy called "series". This website will have many series and I am using a custom field for grouping series. So it will be easy to organize series on frontend in groups.

So here the code for showing 'series' (https://pastiebin.com/5b445ae944a13):

<?php $x = 0; foreach ( $new_mod_series as $cat ): ?>

   <?php $seriestype = get_field( "series_type", $cat ); ?>

   <?php while ( $seriestype == "interview" and $cat_post->have_posts() ): $cat_post->the_post(); ?>

      Show interview series...

   <?php endwhile; ?>

<?php if (++$x == 5) break; endforeach; ?>

This code <?php $seriestype = get_field( "series_type", $cat ); ?> don't run outside of foreach loop and with this I can get value of 'series type' custom field. Then I am using $seriestype == "interview" in while to show only series which are interview.

And now I am not getting expected or 5 foreach results because limiting only 'interview' series to show. But I need to show 5 recent interview series in a section, then other 5 series of another series section.

Is there anyway to solve my problem? With my limited php knowledge, I tried a lot but could not found any solution. Hopefully I was able to explain correctly.

Thanks Julash

Why not query by the custom field? So that you don't have the same query twice (which even now can be used only once). See the acf documentation here regarding your issue https://www.advancedcustomfields.com/resources/query-posts-custom-fields/

In short:

new WP_Query( array( 'post_type' => 'post', 'tax_query' => array( array( 'taxonomy' => 'series', 'field' => 'term_id', 'terms' => $cat->term_id, ) ), 'posts_per_page' => 1, 'ignore_sticky_posts' => 1, 'meta_query' => array( array( 'key' => 'series_type', 'value' => $mod_series, 'compare' => 'IN', ), ) ) );
