PHP PHP script for e-mail form


Hi guys,

I'm a total newbie to php and have tried so many things to create a php script that proces my form on my website and sends me an e-mail when people put in ther information..... It's not totally working. Maybe you can help me?

The forms html code is:

<div class="row">
      <div class="full">
        <hr class="line30">

        <div class="container" style="text-align:left;">
          <form action="kontaktform.php" method="post">

            <label for="name">Dit navn</label>
            <input type="text" id="name" name="name" placeholder="Dit navn..." required>

            <label for="mail">E-mail</label>
            <input type="text" id="email" name="email" placeholder="[email protected]" required>

            <label for="phone">Telefonnummer</label>
            <input type="text" id="phone" name="phone" placeholder="12345678" required>

            <label for="place"><b>Jeg ønsker at...</b></label><br><br>
            <input type="checkbox" id="tilbudillustrationer" name="tilbudillustrationer" value="tilbudillustrationer">
            <label for="tilbudillustrationer" style="margin-right:20px;">Bestille tilbud på illustrationer</label><br><br>
            <input type="checkbox" id="bestilling" name="bestilling" value="bestilling" style="padding:20px;">
            <label for="bestillingsopgave" style="margin-right:20px;">Snakke om en bestillingsopgave</label><br><br>
            <input type="checkbox" id="ide" name="ide" value="ide" style="padding:20px;">
            <label for="ide" style="margin-right:20px;">Jeg ønsker at drøfte en idé</label><br><br>
            <input type="checkbox" id="andet" name="andet" value="andet" style="padding:20px;">
            <label for="andet" style="margin-right:20px;">Andet</label><br><br><br>

            <label for="about">Emne</label>
            <textarea id="about" name="about" placeholder="Min henvendelse drejer sig om..." style="height:200px"></textarea>

            <input type="submit" value="Send">


and my php script kontaktform.php has this code (so far) -

$errors = [];

    // Get POST data
    $name = isset($_POST['name']) ? strip_tags(trim($_POST['name'])) : '';
    $email = isset($_POST['email']) ? trim($_POST['email']) : '';
    $phone = isset($_POST['phone']) ? trim($_POST['phone']) : '';
    $tilbudillustrationer = isset($_POST['tilbudillustrationer']) ? trim($_POST['tilbudillustrationer']) : '';
    $bestilling = isset($_POST['bestilling']) ? trim($_POST['bestilling']) : '';
    $ide = isset($_POST['ide']) ? trim($_POST['ide']) : '';
    $andet = isset($_POST['andet']) ? trim($_POST['andet']) : '';
    $about = isset($_POST['about']) ? trim($_POST['about']) : '';
    $email = isset($_POST['email']) ? strip_tags(trim($_POST['email'])) : '';
    // If no errors, send email
    if (empty($errors)) {
        // Recipient email address (replace with your own)
        $recipient = "[email protected]";

        // Additional headers
        $headers = "From: <$name> Mail: <$email> Telefon: <$phone> Besked: <$about>";

        // Send email
        if (mail($recipient, $message, $headers)) {
            echo "<span style=padding:30px;font-size:24px;font-family:georgia, serif;>Tak for e-mailen, jeg svarer så hurtigt jeg kan | Thank you for the email, I will reply as soon as I can </span><br><br><span style=padding:30px;font-size:20px;font-family:georgia, serif;><b>- Jakob i</b></span><br><br><br><span style=padding:30px;font-size:20px;font-family:georgia, serif;><a style=color:blue;cursor:pointer; onclick=history.back()>Tilbage >></a></span>";
        } else {
            echo "Failed to send email. Please try again later.";
    } else {
        // Display errors
        echo "The form contains the following errors:<br>";
        foreach ($errors as $error) {
            echo "- $error<br>";
} else {
    // Not a POST request, display a 403 forbidden error
    header("HTTP/1.1 403 Forbidden");
    echo "You are not allowed to access this page.";

The script sends information to my e-mail, but there are things left to sort out that I hope you can help me with -

1) the form doesn't send information from checkboxes
2) As I can read - I need some validation for the form, so it's secure

I really hope you can help me - I'm pretty stuck on this.

Your PHP produces this warning:

Warning: Undefined variable $message in D:\web\kontaktform.php on line 27

Indeed, $message is not defined anywhere in this PHP file, and the contents or the 4 checkboxes is picked up but never used. So I am not surprised that it "does not send information from checkboxes". If it sends anything at all, I guess it would be an empty mail.

As for your second question, I would first get it to work, then worry about security 😉
