php - 清理重新提交另一个表单验证 php javascript 解析错误

Question

我清理了，这是错误：

// validation expected data exists
if (!isset($_POST['name'])) { ||
    /* !isset($_POST['last_name']) || */
    !isset($_POST['email']) ||
    /* !isset($_POST['telephone']) || */
    !isset($_POST['comments']) 
died('We are sorry, but there appears to be a problem with the form you submitted.');   

错误说：

解析错误：语法错误，第 37 行 /home/kcorchid/public_html/Tap/Send_Comments.php 中的意外 T_BOOLEAN_OR ...

该行是：

if (!isset($_POST['name'])) { ||

Answer 1

可重复使用且易于更改：

$must_exist = array('name','email','comments','last_name','telephone');

foreach ($must_exist as $item) {
    if (!isset($_POST[$item])) {
        die('We are sorry, but there appears to be a problem with the form you submitted.');
    }
}

// if code executes past this point, all the $must_exist items were found

Answer 2

你只是在错误的地方放了一个支架：

if (!isset($_POST['name']) ||
                                               /*!isset($_POST['last_name']) || */
    !isset($_POST['email']) ||
                                               /*!isset($_POST['telephone']) || */
    !isset($_POST['comments']) )
{
    die('We are sorry, but there appears to be a problem with the form you submitted.');
}

应该工作得很好！
