In this tutorial we will learn how to dynamically populate Advanced custom field select field in WordPress. I was trying a generate a dynamic select list so when I will create a update it from anywhere else it will automatically display in Advanced Custom Field select field.
Advanced custom field how to populate select field PHP Code
First we need PHP array with like, you can use you own custom function, I have used categoryList() in this tutorial.
{
"Programming"=>436,
"Finance"=>437
}
Suppose $category = categoryList(); contains data in format like shown above
function catListACF( $field ) {
//Change this to whatever data you are using.
$category = categoryList();
$field['choices'] = array();
foreach( $category as $key => $item ){
$field['choices'][$key] = $item;
}
return $field;
}
add_filter('acf/load_field/name=cateogry', 'catListACF');
Remember field name slug should be changed in add_filter(‘acf/load_field/name=cateogry’, ‘catListACF’);, here used category.
Use this php code using in your functions.php file.
