The relationship field returns an array of post objects. Each post object contains the ID of the related post. The ACF field functions accept a second parameter, which is the post ID you want to retrieve data from, if it is not the current post. if( $related_pages = get_field( ‘data’ ) ): foreach( $related_pages as … Read more
In my experience, the only way to check the values of the fields is by directly accessing the $_POST vars: if( ( isset( $_POST[‘upload_image’] ) && !empty( $_POST[‘upload_image’] ) )
You could do this with a SQL query via the wpdb class: $query = “SELECT COUNT( DISTINCT meta_value ) FROM $wpdb->postmeta WHERE meta_key = ‘city'”; $unique_cities = $wpdb->get_var( $query ); echo ‘Total number of cities: ‘ . $unique_cities;
<?php if( get_field(‘parent_repeater’) ) : while( has_sub_field(‘parent_repeater’) ) : $some_bool = get_sub_field(‘true’); $sf1 = get_sub_field(‘sub_field_1’); $sf2 = get_sub_field(‘sub_field_2’); if( $some_bool == true ){ echo $sf1 . $sf2; } else { echo $sf1; } endwhile; endif; ?> You must use the non-echoing version of the function. Use the get version. Also, I advise you to use … Read more
My guess is that your problem is that your field type is returning some non-empty value, even if it’s not a URL. For instance, do you have “http://” set as a default value for that field in the admin? If that were the case you could need to use the following as your test: if( … Read more
Looks like you’re missing the $page->ID from the get_field function. $ancestors = get_field(‘ancestor’, $page->ID);
the_field() is an ACF function and will echo content. It follows the WordPress (somewhat) pattern whereby functions with the_ at the front will echo content and functions beginning with get_ return content. Displays the value of the specified field. (this is the same as “echo get_field($field_name)”) http://www.advancedcustomfields.com/resources/functions/the_field/ Using the wrong function, as you have, will … Read more
If main_category is a category (custom taxonomy), then you’re querying it wrong. This should go like this: $electronics = array( ‘numberposts’ => -1, ‘post_type’ => ‘article’, ‘main_category’ => ‘electronics’ ); $query_electronics = new WP_Query( $electronics ); If that’s a custom field, use meta_query: $electronics = array( ‘numberposts’ => -1, ‘post_type’ => ‘article’, ‘meta_query’ => array( … Read more
Until this gets fixed, the only workaround I can see is to intercept the $_POST data and add extra slashes prior to ACF stripping them: /** * @link http://wordpress.stackexchange.com/q/143555/1685 */ function wpse_143555_acf_add_slashes() { if ( ! empty( $_POST[‘fields’] ) ) { foreach ( $_POST[‘fields’] as $k => $v ) { if ( ! is_array( $v … Read more
