Hi, I thought figured this out but I guess I jumped the gun. I am trying to auto calculate the a number field by the total amount of checkboxes that are checked. I have multiple custom fields that I am doing this with.
The top one works perfectly but when I add the second one and so on, it gives me an error.
count(): Argument #1 ($value) must be of type Countable|array
add_action('acf/save_post','calc_titles');
$post_id = 'teams';
function calc_titles($post_id) {
//First Part that works
$value = count(get_field('16th_region_title_year_won'));
$sixteen = "total_16th_region_titles";
update_field($sixteen,$value,$post_id);
//Second Part
$value = count(get_field('3rd_region_title_year_won'));
$third = "total_3rd_region_titles";
update_field($third,$value,$post_id);
}
Thanks!
Went a different route.
// Hook to save_post action
add_action('save_post', 'update_number_field');
function update_number_field($post_id) {
// Check if it's an autosave
if (defined('DOING_AUTOSAVE') && DOING_AUTOSAVE) {
return;
}
// Check if the user has permission to edit the post
if (!current_user_can('edit_post', $post_id)) {
return;
}
// Check if the post type is the one you want to target (e.g., 'post' or 'page')
$post_type = get_post_type($post_id);
if ($post_type != 'team') {
return;
}
// Get the values of the checkbox field
$checkbox_values = get_post_meta($post_id, 'state_title_years_won', true);
// Calculate the number of checked checkboxes
$number_field_value = is_array($checkbox_values) ? count($checkbox_values) : 0;
// Update the number field
update_post_meta($post_id, 'total_state_championships_won', $number_field_value);
}
I must have missed you OP.
The reason it is failing is that you are probably calling get_field() for a field without a value, as you have seen your updated code, you must check that the field is actually an array before you try to count it.
