PHP表單不檢查其他輸入

我制作了一個聯系表格，但是 PHP 只檢查“訊息”，如果填寫了所有其他檢查，則忽略。如果它沒有填寫所有其他檢查作業以及。有人可以幫我修復我的代碼嗎？謝謝。

<?php
$fullName = $customerEmail =  $message = '';
$errors = array('fullName' => '', 'customerEmail' => '', 'message' => '');

if (isset($_POST['submit'])) {
    $myEmail = "xxxxxxxxxxxxx";
    $timeStamp = date("dd/M/YY HH:i:s");
    $body = "";

    $fullName = $_POST['fullName'];
    $customerEmail = $_POST['customerEmail'];
    $chosenSubject = $_POST['subject'];
    $message = $_POST['message'];

    $body .= "From: " . $fullName . " at $timeStamp" . "\r\n";
    $body .= "Email: " . $customerEmail . "\r\n";
    $body .= "Message: " . $message . "\r\n";

    if (empty($fullName)) {
        $errors['fullName'] = "Full name is required. <br>";
    } else {
        if (!preg_match("/^([a-zA-Z' ] )$/", $fullName)) {
            $errors['fullName'] = "Your name must be a valid name.";
        }
        
    }

    if (empty($customerEmail)) {
        $errors['customerEmail'] = "An email is required. <br>";
    } else {
        if (!filter_var($customerEmail, FILTER_VALIDATE_EMAIL)) {
            $errors['customerEmail'] = "Email must be a valid email address.";
        }
    }

    if (empty($message)) {
        $errors['message'] = "A message is required.";
    } 
    
    else {
        mail($myEmail, $chosenSubject, $body);
        header("Location: public/mail_sent.php");
    }
}
?>

最后一個 else 被更改為包含所有欄位的 IF 檢查，并且只有當它們都不為空時才會發送。

<?php
$fullName = $customerEmail =  $message = '';
$errors = array('fullName' => '', 'customerEmail' => '', 'message' => '');

if (isset($_POST['submit'])) {
    $myEmail = "[email protected]";
    $timeStamp = date("dd/M/YY HH:i:s");
    $body = "";

    $fullName = $_POST['fullName'];
    $customerEmail = $_POST['customerEmail'];
    $chosenSubject = $_POST['subject'];
    $message = $_POST['message'];

    $body .= "From: " . $fullName . " at $timeStamp" . "\r\n";
    $body .= "Email: " . $customerEmail . "\r\n";
    $body .= "Message: " . $message . "\r\n";

    if (empty($fullName)) {
        $errors['fullName'] = "Full name is required. <br>";
    } else {
        if (!preg_match("/^([a-zA-Z' ] )$/", $fullName)) {
            $errors['fullName'] = "Your name must be a valid name.";
        }
        
    }

    if (empty($customerEmail)) {
        $errors['customerEmail'] = "An email is required. <br>";
    } else {
        if (!filter_var($customerEmail, FILTER_VALIDATE_EMAIL)) {
            $errors['customerEmail'] = "Email must be a valid email address.";
        }
    }

    if (empty($message)) {
        $errors['message'] = "A message is required.";
    } 
    
    if(!empty($fullName) && !empty($customerEmail) && !empty($message)) {
        mail($myEmail, $chosenSubject, $body);
        header("Location: public/mail_sent.php");
    }
}
?>

您的最后一個 else 應該更改為 IF，檢查是否有任何欄位不為空，然后發送訊息。

if(!empty($fullName) && !empty($customerEmail) && !empty($message)) {

    mail($myEmail, $chosenSubject, $body);

    header("Location: public/mail_sent.php");
}
