Saving all values in “multiple select”
im having a metabox in wordpress with a mutliple select form.
-
adding [] to the
namewas correct, however I allso needed to replace the following save line:update_post_meta( $post_id, 'my_meta_box_select', esc_attr( $_POST['my_meta_box_select'] ) );with the following:
update_post_meta($post_id, 'my_meta_box_select', array_map( 'strip_tags', $_POST['my_meta_box_select'] ) );Thanks alot for the assistance Nate!

Often overlooked, super simple.
The name attribute needs to allow for multiple selections to be sent over
$_POSTas an array. For example:<select name="my_meta_box_select[]" id="my_meta_box_select" multiple="" style="width:300px; height:400px;"> <option value="red">Red </option> <option value="blue">Blue </option> </select>Notice the
[]in the name:name="my_meta_box_select[]"This, alongside the
multipleattribute, will allow your$_POSTvariable to contain all selections as an array. That said,$_POST['my_meta_box_select']will not just be a simple value, but rather will be an array will all selections.讨论(0)
