Ninja Forms API - 无法使用 ninja_forms_submit_data 过滤器更新字段值

Question

我正在使用此代码遍历字段：

add_filter( 'ninja_forms_submit_data', function ( $form_data ) {

    $form_model = Ninja_Forms()->form( $form_data[ 'id' ] );

    foreach( $form_data[ 'fields' ] as $field ){
        $field_model = $form_model->get_field( $field[ 'id' ] );
        $field_key = $field_model->get_setting( 'key' );
        if( 'subject_test' == $field_key ){
            $field_model->update_settings( 'value', 'foo' )->save();
        }
    }

    return $form_data;
} );

subject_test 是我要更改值的字段的键。

我尝试了许多其他方法来更改值，但似乎没有任何效果。

谁能指出我正确的方向？

Answer 1

知道了！

$form_data[ 'fields' ][ $field_id ][ 'value' ] = 'foo';

Answer 2

@Lee 这是我使用的完整功能：

// Change email_admin based on subject using a hidden field
add_filter( 'ninja_forms_submit_data', function ( $form_data ) {
    $form_model = Ninja_Forms()->form( $form_data[ 'id' ] );
    foreach( $form_data[ 'fields' ] as $field ) { // Loop through fields
        $field_model = $form_model->get_field( $field[ 'id' ] );
        $field_key = $field_model->get_setting( 'key' );
        $field_id = $field[ 'id' ];
        if( 'subject_value' == $field_key ) {
            $subject_value = '';
            $subject_value = $form_data[ 'fields' ][ $field_id ][ 'value' ]; // Take subject dropdown value.
            $email_redirect = get_string_between($subject_value, '{', '}'); // Get email from subject value.
            $new_subject = delete_all_between($subject_value, '{', '}'); // Remove {email} from subject value.
            $form_data[ 'fields' ][ $field_id ][ 'value' ] = $new_subject; // Assign new subject value.
        } elseif ( 'subject_send' == $field_key ) {
            if ( isset($email_redirect) )
                $form_data[ 'fields' ][ $field_id ][ 'value' ] = $email_redirect; // Give hidden field the email which is used in send to field.
        } else {
            continue;
        }
    }
    return $form_data;
} );
