I am new to wordpress and Advance Custom field Plugins, I need to get all the custom field value of the type=”POST” in the Custom page Template in wordpress, by getting that value i have to do some functions with the value and i need to pass that value in below code to retrieve Posts
For example here is the code
One of the custom field in My post which i need to retrieve is ‘subject_id’ So ‘subject_id’ value will be something like this “CS2360”
So i need do function like $demo=substr((subject_id_vaue_here),0,2); where i ll be getting the value as “CS” so i need to pass the $demo in below array
<?php
$args = array(
'numberposts' => -1,
'post_type' => 'post',
'meta_query' => array(
'relation' => 'AND',
array(
'key' => 'subject_code',
'value' => $demo,
'compare' => '='
),
array(
'key' => 'categories',
'value' => get_field( "sel_categories" ),
'compare' => '='
)
)
);
$the_query = new WP_Query( $args );
?>
<?php if( $the_query->have_posts() ): ?>
<ul>
<?php while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
<li>
<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
</li>
<?php endwhile; ?>
</ul>
<?php endif; ?>
<?php wp_reset_query(); ?>
Note: I am retrieving the value from the post to the page, so i do no how to select
