我有一個聯繫表單與現有的驗證碼。我創建了表單並在其中組合了上載功能。問題是當我試圖提交沒有驗證碼的表單時，它沒有顯示js提醒或無效的驗證碼提示，但是當我嘗試附加圖像時，提交沒有驗證碼的表單，它被提交。現在代碼亂七八糟。任何人都可以查看條件聲明，看看你能幫我解決這個問題嗎？我不擅長php。PHP表單條件語句
這是我mail.php
<?php
if($_SESSION["captcha"] == $_POST["captcha"]) {
//if($_SESSION["captcha"] == $_POST["captcha"]) {
// we'll begin by assigning the To address and message subject
$to="[email protected]";
$subject="E-mail with attachment";
// get the sender's name and email address
// we'll just plug them a variable to be used later
$from = stripslashes($_POST['fromname'])."<".stripslashes($_POST['fromemail']).">";
// generate a random string to be used as the boundary marker
$mime_boundary="==Multipart_Boundary_x".md5(mt_rand())."x";
// store the file information to variables for easier access
$tmp_name = $_FILES['filename']['tmp_name'];
$type = $_FILES['filename']['type'];
$size = $_FILES['filename']['size'];
// here we'll hard code a text message
// again, in reality, you'll normally get this from the form submission
$message = 'Message from '.$_REQUEST['name'].'
Full Name: '.$_REQUEST['name'].'

當你說「這不是驗證」時，你究竟是什麼意思？ –
何處形？ –
驗證在哪裏？ – Arfeen
