表單每天提交一次空白（每次只有一個小時不同）

Question

我創建了一個使用php郵件腳本提交的HTML表單。我遇到的問題是，表格每天提交一次完全空白，每天晚上一小時後完全空白。我完全陷入困境，我希望有人能幫助發現我的問題。

我粘貼下面的代碼，請注意：html表單的結束位置在使用Adobe CQ5的網站的頁面內，php腳本在單獨的服務器上，我已經刪除了所有驗證以檢查如果這是問題（這不是 - 它仍然提交空白有或沒有我的驗證代碼）。

HTML表單代碼：

Answer 1

您已根據需要標記了幾個字段，但未檢查它們是否實際填充。就拿submit_name例如，你有它標記爲必需（*名稱），但是當表單張貼您做到以下幾點：

if(!isset($_POST['submit_name'])){$submit_name = " ";} 
else{$submit_name = $_POST['submit_name'];} 

這段代碼實際上給它一個價值" "甚至它不提供時。我想你想要做的是防止提交時提供。

//do this check for every required variable 
if (empty($_POST['submit_name']) or empty($_POST['companyName']) or empty($_POST['companyLocation']) or empty($_POST['companyCity'])) { 
    echo 'Not all required fields are set'; 

    //now there are several options. You can just end the page using exit and then the user needs to use his backbutton to get back to the form 
    //exit(); 


    //another option is to send him back yourself 
    //header('location: /form.html'); 
    //exit(); 
} 

//the submit code you have to send the mail 

旁註：

您正在使用isset即使變量張貼這將返回true，但沒有價值。也許你想檢查字符串empty()，以確保它們也包含一些東西。但不使用empty()當你想到一個數字，也可以爲0。
