I’m assuming your $selected variable contains an array of values for the currently selected items? You can’t use selected in this case (with multi select boxes) because it only compares two strings. It won’t test to see if the value is in an array. Instead, use a ternary statement and in_array() <?php foreach ($cats as … Read more
Array is how PHP represents an array when it is converted to a string: echo array( /* anything in here */ ); // output: Array Fortunately for you, PHP doesn’t really like converting arrays to strings, so it will give an error like this: PHP Notice: Array to string conversion in /somefile.php on line 345 … Read more
First off, there’s a problem with your array. Arrays can not have duplicate keys. So, only the first key will be saved. You need to change your form to something like this. <input name=”mainStageSatOrder[theband0][theid]” type=”hidden” class=”band-id” value=”” />”; <input name=”mainStageSatOrder[theband0][theorder]” type=”hidden” class=”band-order” value=”” />”; <input name=”mainStageSatOrder[theband1][theid]” type=”hidden” class=”band-id” value=”” />”; <input name=”mainStageSatOrder[theband1][theorder]” type=”hidden” class=”band-order” value=”” … Read more
WP has a lot of nifty functions in the corners for such stuff. Try this: if ( !empty( $categories ) ) { $excluded_categories = wp_list_pluck( $categories, ‘term_id’); $excluded_categories = implode(‘,’, $excluded_categories); }
Contact Form 7 has a lot of useful hooks you can use to tie custom code into it at various points of the form submission process. They are tragically not well documented at all but you can find them by googling around. You probably want wpcf7_before_send_mail. Something like this in functions.php: function do_stuff($wpcf7) { // … Read more
I had something similar going on when I tried to use the wp_editor() function while inside a custom metabox. It was wanting to save multiple times. Take a look at this. // SAVE Metabox for admin response add_action(‘post_updated’, ‘display_jwl_wp_etickets_response_meta_box_save’); function display_jwl_wp_etickets_response_meta_box_save( $post_id ){ if( defined( ‘DOING_AUTOSAVE’ ) && DOING_AUTOSAVE ) return; if( !isset( $_POST[‘jwl_wp_etickets_editor_box_nonce_check’] ) … Read more
This is probably impossible since WP-CLI pass the arguments directly to wp_insert_posts. I’m automating this with wp eval. For example: wp eval ‘wp_set_object_terms(12 , array(1, 2, 3), “course”);’ The post id can be obtained when you create the post with –porcelain: wp post create … –porcelain Or by normal query with post title: wp eval … Read more
The post_class() function just is a wrapper for get_post_class(). Keep in mind that the latter does not echo, but returns an Array so you have to do something like what post_class() does: $classes = join( ‘ ‘, get_post_class() ); Your code (could) would look like the following. I changed the if check as well to … Read more
Seems like a silly question, but are there exactly 2 users in the database? Or are there more. The only thing I can see happening is because you are setting to 3, it’s looping back through. Another thing to try is checking the peterpanpan user, to see if he has the custom_role twice in his … Read more
I created a Kint plugin that works really well. I also integrates with the Debug Bar plugin. You can download it at: http://wordpress.org/extend/plugins/kint-debugger/ There are a few functions to help you out with WordPress specific globals: dump_wp_query() dump_wp() dump_post() For printing arrays in a styled, collapsible format you would do the following. $foo_bar = array( … Read more
