Php 基于不带jquery的下拉列表的联系表单7条件值

我正在尝试获取函数的下拉选项值。根据下拉值，它必须发送电子邮件。以下开关箱代码适用于文本框，但不适用于下拉列表（选择）。我们必须在此表单中执行更多流程，以避免接触表单7管道选项

 add_action( 'wpcf7_before_send_mail', 'wpcf7_do_something_else_with_the_data', 90, 1 );
        
        function wpcf7_do_something_else_with_the_data( $WPCF7_ContactForm ){
         $submission = WPCF7_Submission :: get_instance();
        
            if ( $submission ){
                $posted_data = $submission->get_posted_data();      
                if ( empty( $posted_data ) ){ return; }
                
                
                $favcolor = $posted_data['location'];
    
                switch ($favcolor) {

在5.1和5.2之间的某个时刻，CF7的开发人员决定将

selects

作为数组返回。这是一种痛苦，因为它让我在更新网站时感到头疼

但撇开观点不谈

试着改变

$favcolor=$posted_数据['location']

到

$favcolor=$posted_数据['location'][0]
