  • This is what I have figured out so far…. but I can’t seem to get the seed to work with the session and keeping random working with pagination.

    Not sure if this is a Genesis issue at this point, my code, or WordPress. 

    global $post;
  
$query = new WP_Query( 
  array( 
    'post_type' => 'artist', 
    'posts_per_page' => -1,
    'fields' => 'ids',
    'meta_query' => array(
    	array(
        	'key' => 'artist_gallery'
            )
		  )
        ) 
      );
        $seed = $_SESSION['seed'];
        if (empty($seed)) {
          $seed = rand();
          $_SESSION['seed'] = $seed;
        }
        $args = array( 
            'post_type' => 'attachment', 
            'post_status' => 'inherit',
            'orderby' => 'RAND(' . $seed . ')',
            'post_mime_type' => 'image', 
            'posts_per_page' => 30, 
            'post_parent__in' => $query->posts, 
            'order' => 'DESC' 
            );
  
 	global $wp_query;
    $wp_query = new WP_Query( $args ); 

    if ( have_posts() ) : 
        while ( have_posts() ) : the_post(); 
			$image_attachment = get_attachment_link( get_the_ID() );
			$img_src = wp_get_attachment_image_src( get_the_ID(), 'medium');
			$alt = get_the_title();
echo '	
			<div class="col-md-4"> 
				<a href='. $image_attachment .'>
					<img src="'. $img_src[0] .'" alt="'. $alt .'" />
				</a>
				<p>'. $image["caption"] .'</p>
			</div>
';
	endwhile;
	do_action( 'genesis_after_endwhile' );
endif;				

// Restore original Post Data
	wp_reset_postdata();

  • Has anyone figured out how to do this dynamically for multiple keys and values. I tried something like this (below) but I can’t get it to work.

    I have quite a few fields I need to be filtering for. I can get each field to work one at a time, but the second I try to do more than one, I see only field being filtered when i run “echo $GLOBALS[‘wp_query’]->request;”

    Any help would be HUGE. I have been stuck on this for quite some time! Thank you in advance. 

    
		add_filter('posts_where', 'my_posts_where');
		function my_posts_where( $where ) {
			/* if( isset($_GET['feelings_$_feeling']) ) {
			$where = str_replace("meta_key = 'feelings_$", "meta_key LIKE 'feelings_%", $where);
			return $where;
			} */

			$rootkeys[] = $_GET;
			global $wpdb; //TESTING
			foreach($rootkeys as $rootkey) {
				foreach($rootkey as $key => $value) {
					$partialkey = explode("$",$key);
					$keya = $partialkey[0];
					$keyb = 'meta_key = \''.$keya.'$';
					$keyc = 'meta_key LIKE \''.$keya.'%'; //this = was LIKE, should it be?
			// $where = str_replace($keyb, $keyc, $where);
			$where = str_replace($keyb, $keyc, $wpdb->remove_placeholder_escape($where));
			}
			}
			return $where;

		}

  • Ok, got it…. finally…

    
	$rootkeys[] = $_GET;
	foreach($rootkeys as $rootkey) {
		foreach($rootkey as $key => $value) {
			$partialkey = explode("$",$key);
			$keya = $partialkey[0];
			$keyb = 'meta_key = \''.$keya.'$';
			$keyc = 'meta_key LIKE \''.$keya.'%';
	$where = str_replace($keyb, $keyc, $where);
	}
	}
	return $where;

  • Ok, so I got this far…..
    $keya outputs feelings_$ and medical_use_$ which is CORRECT….. But… this still doesn’t work. 

    
	$rootkeys[] = $_GET;
	foreach($rootkeys as $rootkey) {
		foreach($rootkey as $key => $value) {
			$partialkey = explode("$",$key);
			$keya = $partialkey[0].'$';
	$where = str_replace("meta_key = $keya", "meta_key LIKE 'feelings_%", $where);
	}
	}
	return $where;

  • I am trying to figure out how I can just use $_get, and pull the array.

    Using this 

    // If you have the following URL :

// http://www.example.com/test.php?a=10&b=plop

// Then $_GET will contain :

array
  'a' => string '10' (length=2)
  'b' => string 'plop' (length=4)

    From https://stackoverflow.com/questions/5415224/how-to-set-get-variable

    So, this should loop through each parameter and value in the URL.
    However; if I understand this filter, it is only pulling part of the value, and I can’t figure out what this is actually populating for $rootkey. I can’t figure out how to see that ECHO. 

    	
$rootkeys[] = $_GET;
	foreach($rootkeys as $rootkey) {
	$where = str_replace("meta_key = 'feelings_$", "meta_key LIKE 'feelings_%", $where);
	
	}
	return $where;

  • Hey guys, I almost had it figured out. I don’t know why I didn’t think of just using a $GET. So as long as 1 filter is selected at a time, it now works. But the second that I select a filter, and a medical_use (url of something like ” strains?feelings_$_feeling=Euphoric&medical_use_$_medical=Seizures ”

    Does anyone have any idea how I can get this to work for any meta_query in the URL?

    
add_filter('posts_where', 'my_posts_where');
function my_posts_where( $where ) {
	if( isset($_GET['feelings_$_feeling']) ) {
	$where = str_replace("meta_key = 'feelings_$", "meta_key LIKE 'feelings_%", $where);
	return $where;
	}
	
	if( isset($_GET['medical_use_$_medical']) ) {
	$where = str_replace("meta_key = 'medical_use_$", "meta_key LIKE 'medical_use_%", $where);
	return $where;
	}
	
	return $where;
}

  • Has anyone been able to do this with a hook as opposed to editing the acf plugin?
    How can I add this code in, and still allow for updates to ACF?
