A meta_value field is always text; the fieldtype in the database structure is longtext, so unless you’re explicitly typecasting when retrieving it (i.e. $price = (float)$custom[‘price’][0]; – which won’t help with ordering in the first place), you can’t ‘adjust’ the custom field data – it’s always stored as text. Having said that, you should simply … Read more
Ok, this is actually about the output as you said in your comment. I suppose you know, you can do modification like this: // assumed a single result is returned as string $your_post_meta = get_post_meta( get_the_ID(), ‘your_post_meta’, true ); // lets add something $your_modified_post_meta=”My post meta: ” . $your_post_meta; So far so obvious I would … Read more
As Andreas Krischer suggested, I fixed using an script to update all the old values and then only using the wp_insert_post to create the custom field for the new posts. The script that I used: INSERT INTO wp_postmeta( post_id, meta_key, meta_value ) SELECT wp_posts.ID, ‘municipi’, ” FROM wp_posts WHERE wp_posts.post_status=”publish” AND wp_posts.post_type=”post” Here I’m updating … Read more
The parameter is called: posts_per_page so you are missing the plural »s« – more information about WP_Query – Pagination Parameters at the codex.
I guess you’re not after the current post/page ID, but rather trying to find the ID for some url from your site. Then you should try out the handy url_to_postid() WordPress core function. It returns the post/page ID if it exists, else 0. Example: echo url_to_postid( ‘http://example.com/2014/11/14/hello-world’ ); // Outputs the post ID as 1 … Read more
See get_post_meta() Example: get_post_meta($post->ID, ‘EXAMPLEFIELD’, true);
you have to make a javascript code similar to this… jQuery(function ($) { name = $(‘#name’).val(); $(‘#name’).data(‘old_value’,name); window.onbeforeunload = function () { if ($(‘#name’).data(‘old_value’) !== $(‘#name’).val()) return ‘You have unsaved changes!’; } }); here’s a demo page… try closing the page after changing the value of the textbox there…
Sometimes it is more useful to look at the task outside of the WordPress field, but from true programming. You can use custom SQL query to get your users ids and then do what you want with them. Place the code below into functions.php function wpse_177536_get_user_ids(){ global $wpdb; $sql = “SELECT user_id FROM $wpdb->usermeta WHERE … Read more
You could do this with jquery. I have a similar code on use which you could probably easily edit to your needs: load the admin js (I load css too but you can remove that) function wpse181868_admin_css_js() { wp_register_style( ‘bones_admin_css’, get_template_directory_uri() . ‘/library/css/admin.css’, false ); wp_enqueue_style( ‘bones_admin_css’ ); //adding scripts file in the footer wp_enqueue_script( … Read more
If you would have created your own WP_Query, you could have done it this way: <?php $args = array( ‘orderby’ => ‘meta_value_num’, ‘order’ => ‘ASC’, ‘meta_key’ => ‘price’ ); $new_query = new WP_Query( $args ); ?> See the examples in the docs: https://codex.wordpress.org/Class_Reference/WP_Query#Order_.26_Orderby_Parameters Since you are using the Mainloop, you need to act a bit … Read more
