函数自定义_回调($form,&$form_状态){
$output=array();
$output['#markup']=“谢谢!您的邮件已发送!”;
返回$output;
}
这是可行的,但整个验证功能被忽略。
如何在调用custom_callback()之前验证表单 不要使用自定义Ajax回调,请尝试以下代码,它将调用表单的submitForm()方法,从而在调用submitForm()之前也调用validateForm()方法
简而言之,它将通过Ajax提交表单。不要使用自定义Ajax回调,请尝试以下代码,它将调用表单的submitForm()方法,从而在调用submitForm()之前也调用validateForm()方法 简而言之,它将通过Ajax提交表单
$form['actions']['submit'] = array(
'#attributes' => array (
'class' => array (
'use-ajax-submit'
