[英]php form validation required fields
我有一個php表單,我正在嘗試為此填寫必填字段,但是我似乎無法使其正常運行,而且我知道我所缺少的東西。 我只需要使表格要求$ name $ bank $ email和$ phone。
<?php
/* Set e-mail recipient */
$myemail = "email@email.com";
/* Check all form inputs using check_input function */
$name = check_input($_POST['name'], "Enter your name");
$bank = check_input($_POST['bank'], "Enter your name");
$email = check_input($_POST['email']);
$phone = check_input($_POST['phone']);
$headphones = check_input($_POST['headphones']);
$subject = "Allied Affiliated Funding - Bose Landing Page Form Submission";
/* If e-mail is not valid show error message */
if (!preg_match("/([\w\-]+\@[\w\-]+\.[\w\-]+)/", $email))
{
show_error("E-mail address not valid");
}
/* Let's prepare the message for the e-mail */
$message = "Hello!
Your contact form has been submitted by:
Name: $name
Bank: $bank
E-mail: $email
Phone: $phone
Head Phones: $headphones
End of message
";
/* Send the message using mail() function */
mail($myemail, $subject, $message);
/* Redirect visitor to the thank you page */
if($_POST['headphones'] == Yes){
header("Location: landing1/thank-you-bose.html");
}
else {
header("Location: landing1/thank-you.html");
}
exit();
/* Functions we used */
function check_input($data, $problem='')
{
$data = trim($data);
$data = stripslashes($data);
$data = htmlspecialchars($data);
if ($problem && strlen($data) == 0)
{
show_error($problem);
}
return $data;
}
function show_error($myError)
{
?>
<html>
<body>
<b>Please correct the following error:</b><br />
<?php echo $myError; ?>
</body>
</html>
<?php
exit();
}
?>
我看過一些有關如何完成此操作的教程,但似乎沒有一種解決方案有效。
我認為您的問題出在這條線上
if($_POST['headphones'] == Yes){
它必須是
if($_POST['headphones'] == "Yes"){
您沒有名為Yes的變量,所以我認為您想檢查耳機的內容是否為“ yes”。
