甚至有錯誤的PHP過程窗體

Question

當我想到php和服務器端腳本時，我很新，所以請和我一起裸照。我有一個處理文件來驗證並通過我的網站發送一封聯繫表。就發送數據而言，一切都很好，但它不能正確處理任何錯誤。現在，如果必填字段爲空，則不應允許發送消息。但現在它仍然發送消息。我不知道如何解決這個問題，所以任何幫助表示讚賞。

這裏是我的PHP

<?php 
if(($_SERVER['REQUEST_METHOD'] =='POST') && (!empty ($_POST['action']))): 

if (isset ($_POST['myname'])){$myname=$_POST['myname'];} 
if (isset ($_POST['myphone'])){$myphone=$_POST['myphone'];} 
if (isset ($_POST['myemail'])){$myemail=$_POST['myemail'];} 
if (isset ($_POST['job'])){$job=$_POST['job'];} 
if (isset ($_POST['comments'])){ 
    $comments= filter_var($_POST['comments'], FILTER_SANITIZE_STRING);} 

$formerrors = false; 



     if($myname === '') : 
     $err_myname = '<div class="error"> Sorry, your name is rquired</div>'; 
     endif;  

     if($myphone === ''): 
     $err_myphone = '<div class="error"> Sorry, your phone number is rquired</div>'; 
     endif;  

     if($myemail === ''): 
     $err_myemaile = '<div class="error"> Sorry, your email is rquired</div>'; 
     endif;  

     if($job === ''): 
     $err_job = '<div class="error"> Sorry, your business is rquired</div>'; 
     endif;  



if (!($formerrors)) : 
$to = "email@email.com"; 
$subject = " Request from $myname"; 

$message = "A new show and tell request from:\n 
      $myname \n 
      $myemail\n 
      $myphone\n 
      $job\n 
      $comments\n"; 
$replyto = "From: $myemail"; 


if(mail($to, $subject, $message)): 
    $msg ="Thanks for filling out our form"; 
    else: 
    $msg = "There was a problem sending the message"; 
    endif; //mail data 

endif; //check errors 

endif; //form submitted 

?> 

如果我需要張貼任何更多的信息，如實際的HTML，請讓我知道。

當遇到錯誤時，您沒有設置$formerrors=true，所以它始終設置爲false並始終發送郵件。

嘗試這樣：

if($myname === '') : 
    $err_myname = '<div class="error"> Sorry, your name is rquired</div>'; 
    $formerrors=true; 
endif;
