ACF clone field not working

The ACF (Advanced Custom Fields) plugin is a powerful tool for creating custom fields in WordPress. One common issue that users may encounter is the “ACF clone field not working” problem. This occurs when the clone field functionality of ACF does not function as expected.

To resolve this issue, you can use the acf/load_value filter hook to manually clone the field value. Here’s an example code snippet that demonstrates how to clone an ACF field:

function wpsnippets_clone_acf_field( $value, $post_id, $field ) {
    // Check if the field is a clone field
    if ( $field['type'] === 'clone' ) {
        // Get the original field value
        $original_value = get_field( $field['clone'] );

        // Clone the original value
        $cloned_value = $original_value;

        // Return the cloned value
        return $cloned_value;
    }

    // Return the original value for non-clone fields
    return $value;
}
add_filter( 'acf/load_value', 'wpsnippets_clone_acf_field', 10, 3 );

In this code snippet, we define a custom function wpsnippets_clone_acf_field that hooks into the acf/load_value filter. Inside the function, we check if the field being loaded is a clone field by comparing its type with 'clone'. If it is a clone field, we retrieve the original field value using the get_field() function and assign it to the $original_value variable. Then, we clone the original value by assigning it to the $cloned_value variable. Finally, we return the cloned value.

By using this code snippet, the ACF clone field should work as expected, allowing you to clone and modify field values as needed.

Examples

Example 1: Cloning ACF fields using the acf_duplicate_field() function

This example demonstrates how to clone an Advanced Custom Fields (ACF) field using the acf_duplicate_field() function. This function allows you to create a duplicate of an existing ACF field, including all its settings and values.

$field_id = 123; // ID of the field to be cloned
$new_field_id = wpsnippets_acf_duplicate_field($field_id);

The acf_duplicate_field() function takes the ID of the field to be cloned as a parameter and returns the ID of the newly created field. You can then use this new field ID to perform any further operations or modifications.

Example 2: Cloning ACF fields programmatically using acf_duplicate_field()

In this example, we will programmatically clone an ACF field and assign it to a specific location using the acf_duplicate_field() function.

$field_id = 123; // ID of the field to be cloned
$new_field_id = wpsnippets_acf_duplicate_field($field_id);

$location = array(
    array(
        array(
            'param' => 'post_type',
            'operator' => '==',
            'value' => 'page',
        ),
    ),
);

acf_update_field(array(
    'ID' => $new_field_id,
    'location' => $location,
));

After cloning the field, we can assign it to a specific location using the acf_update_field() function. In this example, we assign the cloned field to all pages.

Example 3: Cloning ACF fields with modified settings

In this example, we will clone an ACF field and modify some of its settings before saving it as a new field.

$field_id = 123; // ID of the field to be cloned
$new_field_id = wpsnippets_acf_duplicate_field($field_id);

$new_field_settings = array(
    'key' => 'field_new_field_key',
    'label' => 'New Field Label',
    'name' => 'new_field_name',
    'instructions' => 'New field instructions.',
    // Modify other field settings as needed
);

acf_update_field(array(
    'ID' => $new_field_id,
    'key' => $new_field_settings['key'],
    'label' => $new_field_settings['label'],
    'name' => $new_field_settings['name'],
    'instructions' => $new_field_settings['instructions'],
    // Update other field settings as needed
));

After cloning the field, we can modify its settings by updating the relevant values in the $new_field_settings array. In this example, we change the field key, label, name, and instructions. Finally, we save the modified field using the acf_update_field() function.
