联系表单返回错误，特别是“电子邮件”字段

Question

I have a contact form field that uses AJAX to submit the form, and PHP.

I have a small problem. I keep receiving an error that states," the request was successful, but the form was not filled out correctly. " This applies to the ' email ' field. The form does not get submitted, and a user has to refill out the form.

Somehow, any email address entered is not valid.

Does anyone know why that could be?

/* Email Variables */
$emailSubject = 'You have received an inquiry from your website';
$webMaster = 'info@3elementsreview.com';

/* Data Variables */
$first = Trim(stripslashes($_POST['First']));
$last = Trim(stripslashes($_POST['Last']));
$email = Trim(stripslashes($_POST['E-Mail']));
$message = Trim(stripslashes($_POST['Message']));
$tempt = $_POST['tempt'];
$tempt2 = $_POST['tempt2'];

if ($tempt == 'http://' && empty($tempt2)) {

    $error_message = '';
    $reg_exp = "/^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9­-]+\.[a-zA-Z.]{2,5}$/";

    if(!preg_match($reg_exp, $email)) {

        $error_message .= "<p>A valid email address is required.</p>";
    }
    if (empty($first)) {
        $error_message .= "<p>Please provide your first name.</p>";
    }
    if (empty($last)) {
        $error_message .= "<p>Please provide your last name.</p>";
    }
    if (empty($message)) {
        $error_message .= "<p>Comments box cannot be left empty.</p>";
    }

    if (!empty($error_message)) {

        $return['error'] = true;
        $return['msg'] = "<h3> The request was successful, but the form is not filled out correctly.</h3>".$error_message;
        echo json_encode($return);
        exit();

    } else {

        $return['error'] = false;
        $return['msg'] = "<p>Thank you for contacting us. We definitely value your feedback," .$first .".</p>";
        echo json_encode($return);
    }

} else {

        $return['error'] = true;
        $return['msg'] = "<h3>There was a problem while sending this form. Try it again.</h3>";
        echo json_encode($return);
}

Answer 1

The problem is your email input name attribute.

Your input is:

<input name="E-mail" title="E-Mail Address is Required" id="email" placeholder="Email Address" type="email" maxlength="50">

and you're accessing it using $_POST['E-Mail'] (uppercase M ). Note that array index are case sensitive.

Change that line to match your input's name as follows:

$email = Trim(stripslashes($_POST['E-mail']));
