wordpress聯繫表格模板

Question

我在教程的幫助下設計了聯繫表格模板，然後將模板添加到頁面中。如果任何字段爲空或顯示成功消息，我試圖顯示錯誤消息。它正確顯示錯誤信息，但是當輸入所有字段時，它顯示一個空白頁。無法弄清楚我做錯了什麼。這是我的整個代碼。

<?php 
/* 
Template Name: Contact 
*/ 

?> 

<?php 
$msgSubmission = false; 
$nameError = ''; 
$emailError = ''; 
$commentError = ''; 

if(isset($_POST['submitted'])) { 

    if(trim($_POST['name']) === '') { 
     $nameError = 'Please enter your name.'; 
     $hasError = true; 
    } else { 
     $name = trim($_POST['name']); 
    } 

    if(trim($_POST['email']) === '') { 
     $emailError = 'Please enter your email address.'; 
     $hasError = true; 
    } else if (!preg_match("/^[[:alnum:]][a-z0-9_.-]*@[a-z0-9.-]+\.[a-z]{2,4}$/i", trim($_POST['email']))) { 
     $emailError = 'You entered an invalid email address.'; 
     $hasError = true; 
    } else { 
     $email = trim($_POST['email']); 
    } 

    if(trim($_POST['comments']) === '') { 
     $commentError = 'Please enter a message.'; 
     $hasError = true; 
    }else if(function_exists('stripslashes')) { 
     $comments = stripslashes(trim($_POST['comments'])); 
    } else { 
     $comments = trim($_POST['comments']); 
    } 

    if((isset($name) && $name!='') && (isset($email) && $email!='') && (isset($comments) && $comments!='')) { 
     $msgSubmission = true; 
    } 

} ?> 

<?php get_header();?>

Answer 1

首先將此行添加到腳本的頂部。

$hasError = false; 

然後使用此代碼塊來顯示成功消息。

if(!$hasError) { 
// display success message. 
} 

希望這可以幫助你。
