On my site, I check if an array doesn't exceed 3 values. Now I want to doe this as well on the quick edit form.
So far, I get the message only when I refresh the browser.
The code I use when I save the quick edit:
if ( array_key_exists( 'speciality', $_POST ) ){
// update_post_meta( $post_id, 'med-spec', $_POST[ 'speciality' ] );
// inlezen specialiteiten
$specs = preg_split("/[\s,]+/", $_POST['speciality']);
// check of er maximum 3 ingevuld zijn
if (count($specs) < 4){
update_post_meta( $post_id, 'med-spec', $_POST[ 'speciality' ] );
} else {
$_SESSION['my_admin_notices'] = "<div class='error'><p>Maximum 3 specialiteiten!</p></div>";
return false;
}
}The code above checks if the array is maximum 3 values long and puts a message in the session when it is not.
On my page I recall the session:
function my_admin_notices(){
var_dump($_SESSION['my_admin_notices']);
if(isset($_SESSION['my_admin_notices'])) {
print $_SESSION['my_admin_notices'];
} else {
$value = '';
}
unset($_SESSION['my_admin_notices']);
}
add_action( 'admin_notices', 'my_admin_notices' );But this shows the message only on refreshing the browser.
Is there a hook for this? Or must this be done through javascript?
