If get_fields is empty not working

  • Hey guys,

    I’m struggling with a piece of code that is easy but I don’t get my error.

    I’m using this:
    ` $query_array = array(
    ‘post_status’ => ‘publish’,
    ‘post_type’ => ‘show-item’,
    ‘posts_per_page’ => $params[‘number_of_items’],
    ‘orderby’ => $params[‘orderby’],
    ‘order’ => $params[‘order’]
    );`

    And it’s working perfectly but I want to add a condition if a ACF field is not empty so i’m adding this piece of code right after the one above

    `if (get_field(‘date_de_debut’)) {
    $query_array[‘meta_key’] = ‘date_de_debut’;
    $query_array[‘orderby’] = ‘meta_value’;
    }`

    It looks like the get_field does not return anything. I tried a lot of method like 

    $value = get_field('date_de_debut');
if (!empty($value)) {
...
}

    But again it looks like the field does not return anything. If I remove the ‘if’ statement the order works well accoridng to my meta value…

    Thanks guys!

  • You’re only setting the order. You also need to use “meta_value” and “meta_compare” settings https://developer.wordpress.org/reference/classes/wp_query/#custom-field-post-meta-parameters

  • It’s working well with the IF condition so this is not the problem 🙂 The problem is that the variable is always empty even if I ise get_field() or the_field() 🙂

    If I use this code like this (without the if) it’s ordering like a charm !

    $query_array = array(
‘post_status’ => ‘publish’,
‘post_type’ => ‘show-item’,
‘posts_per_page’ => $params[‘number_of_items’],
‘orderby’ => $params[‘orderby’],
‘order’ => $params[‘order’]
);
$query_array[‘meta_key’] = ‘date_de_debut’;
$query_array[‘orderby’] = ‘meta_value’;

  • That is because your query is not eliminating posts that don’t have a value

    
$query_array['meta_value'] = '';
$query_array['meta_compare'] = '!=';

    Other than this I don’t see an issue unless ACF is unable to figure out the post ID. Are you using the global $post variable for your loop? If not then you need to supply the correct post ID to get the value from in the second argument to the_field() or get_field().

  • They all have a value, this snippet replace the existing value

    if (get_field(‘date_de_debut’)) {
$query_array[‘meta_key’] = ‘date_de_debut’;
$query_array[‘orderby’] = ‘meta_value’;
}

    I think this has to be with the post ID. But why is it working if I use this:
    $query_array = array(
    ‘post_status’ => ‘publish’,
    ‘post_type’ => ‘show-item’,
    ‘posts_per_page’ => $params[‘number_of_items’],
    ‘orderby’ => ‘meta_value’,
    ‘meta_key’ => ‘date_de_debut’,
    ‘order’ => $params[‘order’]
    );

  • Are you sure that this has the right values?

    

‘orderby’ => $params[‘orderby’],
‘order’ => $params[‘order’]

  • Yeah ! It’s working well with both code 🙂
    The only problem is here
    $value = get_field(‘date_de_debut’);

    I think that $value is always empty.

    An other example if I use this:

    $value = get_field('date_de_debut');
if (empty($value)) {
$query_array[‘meta_key’] = ‘date_de_debut’;
$query_array[‘orderby’] = ‘meta_value’;$
}

    The order change and works well according to the meta_key ‘date_de_debut’

  • Please post the code for your loop over the query results

  • It comes from a theme that we bought 🙂

    public function render($atts, $content = null) {

  • I’m not familiar with this code, but I can tell you that this is not where you would output anything. It would be in whatever template part the function musea_shows_get_cpt_shortcode_module_template_part is loading.

  • yeah this is not the output but it takes tu arguments here:

    public function getQueryArray($params){
		$query_array = array(
			'post_status'    => 'publish',
			'post_type'      => 'show-item',
			'posts_per_page' => $params['number_of_items'],
			'orderby'        => $params['orderby'],
			'order'          => $params['order']
		);
		
		$field = get_field('date_de_debut');
		if (!empty ($field)) {
			$query_array['meta_key'] = 'date_de_debut';
			$query_array['orderby'] = 'meta_value';
}

    So there is probably a solution there !

  • $query_array = array(
   'post_status'    => 'publish',
   'post_type'      => 'show-item',
   'posts_per_page' => $params['number_of_items'],
   'meta_key'	    => 'date_de_debut',
   'orderby'	    => 'meta_value',
   'order'          => $params['order']
);

    This code works well. The only problem is that the order posts does not match the criteria so it returns: no post match your criteria.

    I just need to change the orderby and the meta_key if get_field(‘date_de_debut) is not empty

  • Oh yeah sorry this is the real query

    <?php

			if($query_results->have_posts()):
				while ( $query_results->have_posts() ) : $query_results->the_post();
					$single_params = array();
					$single_params['title_tag'] = $title_tag;
					$single_params['show_single_layout'] = $show_single_layout;
					$single_params['show_id'] = get_the_ID();
					$single_params['article_classes'] = $this_object->getArticleClasses( $params );
					$single_params['show_category'] = $show_category;
					$single_params['show_date_range'] = $show_date_range;
					$single_params['image_proportions'] = $image_proportions;

					echo musea_elated_execute_shortcode('eltdf_show_single', $single_params);
				endwhile;
			else:
				esc_html_e( 'Sorry, no posts matched your criteria.', 'musea-shows' );
			endif;
		
			wp_reset_postdata();
		?>

  • I Tried to change the last query with this one

    <?php
			// An array of arguments
			$args = array(
				'post_status'    => 'publish',
				'post_type'      => 'show-item',
				'posts_per_page' => $params['number_of_items'],
				'orderby'		 => $params['orderby'],
				'order'          => $params['order'],
				'meta_query' => array( // WordPress has all the results, now, return only the events after today's date
	            array(
	                'key' => 'date_de_debut', // Check the start date field
	                'value' => date("Y-m-d"), // Set today's date (note the similar format)
	                'compare' => '>=', // Return the ones greater than today's date
	                'type' => 'DATE' // Let WordPress know we're working with date
	                )
	            ),
			);
			$field = get_field('date_de_debut');
			if (!empty ($field)) {
				$args['meta_key'] = 'date_de_debut';
				$args['orderby'] = 'meta_value';
			}
			// The Query
			$the_query = new WP_Query( $args );
			
			// The Loop
			if ( $the_query->have_posts() ) {
			
			while ( $the_query->have_posts() ) : $the_query->the_post(); 
			    $single_params = array();
					$single_params['title_tag'] = $title_tag;
					$single_params['show_single_layout'] = $show_single_layout;
					$single_params['show_id'] = get_the_ID();
					$single_params['article_classes'] = $this_object->getArticleClasses( $params );
					$single_params['show_category'] = $show_category;
					$single_params['show_date_range'] = $show_date_range;
					$single_params['image_proportions'] = $image_proportions;

					echo musea_elated_execute_shortcode('eltdf_show_single', $single_params);
			endwhile;
			
			} else {
			    esc_html_e( 'Sorry, no posts matched your criteria.', 'musea-shows' );
			}
			/* Restore original Post Data */
			wp_reset_postdata();
		?>

    Butsame problem. Any idea?

  • My suggestion is to contact the theme author and ask them how you can alter the query to add additional arguments for custom fields and how to show custom fields.
