One way would be to keep track of which years you’ve already printed. Using your code: <?php $args = array( ‘post_type’ => ‘attachment’, ‘post_mime_type’ => ‘image’, ‘numberposts’ => -1, ‘orderby’ => ‘menu_order’, ‘order’ => ASC ); $attachments = get_posts( $args ); echo ‘<table id=”bibliography”>’; if ( $attachments ) { $already_printed_years = array(); foreach ( $attachments … Read more
The answer by felipelavinz assumes that there is an array of dates stored in the post_meta of each post, but the way I read your question and sample code it seemed as though you have one date specified per post? If this is true (one date per post) then the following would suit you better … Read more
Your syntax is complete wrong in your meta_query. A key/value pair in an array should be in the format of ‘key’ => ‘value’. Your format is ‘key’, ‘value’ which in context of an array translate to 0 => ‘key’, 1 => ‘value’. That is why your meta_query does not work. Your failure is also due … Read more
Use a meta_query and set type to NUMERIC– $query->set(‘meta_query’, array( array( ‘key’ => ‘_ai_price_int’, ‘value’ => array(0, 4000), ‘compare’ => ‘BETWEEN’, ‘type’ => ‘NUMERIC’ ) )); $query->set(‘meta_key’, ‘_ai_price_int’); $query->set(‘orderby’, ‘meta_value_num’);
At first glance, I would think your query isn’t correct. Are you echoing out the variables to make sure they are correct? If you are setting ‘post_per_page’ => 4 and you are getting 5 posts, then something seems a bit off. Where it is a number, I believe you can leave off the quotes around … Read more
if ( !$value ) evaluates to TRUE when the value is 0. Alternative: if ( ! isset ( $_POST[‘_ordre’] ) ) return delete_post_meta( $post_id, ‘_ordre’ ); update_post_meta( $post_id, ‘_ordre’, $_POST[‘_ordre’] ); You don’t need add_post_meta(), the call to update_post_meta() will do that automatically.
I’m not sure if I get you right, but if you’re trying to query by multiple meta keys where the number of meta keys varies, then below is what I am using for the same purpose. Basically it adds meta query one after another if the corresponding input is existent. <form action=”” method=”post”> <input name=”item_name” … Read more
Sort alphabetically by custom field
Your order seems arbitrary, so there is no clear way to express it as query parameters. The closest to micromanaging order is by post__in, but then you have to have all post IDs and it won’t be sane at all for any significant amount of posts. You might want to simply create and fill another … Read more
Have you try too remove all tag from content then add li ? $content=”<li>”.strip_tags(get_field(‘artist’)).'</li>’;
