Form error in my PHP code

Question

Well, have been recently learning PHP for a project. So, to practice, I'm trying forms: The HTML code:

<!DOCTYPE html>
<html>
<head>
<title>Raportoni</title>
<style type="text/css">
</style>
</head>
<body>
<p></br></p>
<form action="form.php" method="post">
Emri : <input type="text" name="emri">
</br></br>
Mbiemri : <input type="text" name="mbiemri">
</br></br>
Adresa : <input type="text" name="adresa">
</br></br>
Numri i telefonit : <input type="text" name="numri">
</br></br>
Email : <input type="text" name ="email">
</br></br>
Nje pershkrim i shkurter i asaj qe ju ka ndodhur : </br> <textarea name="pershkrim"></textarea>
</br>
<input type="submit" value="Dergo">
</form>
</body>
</html>

And the PHP code:

<!DOCTYPE html>
<html>
<head>
</head>
<body>
<?php
    $emri=$_POST["emri"];
    $mbiemri=$_POST["mbiemri"];
    $adresa=$_POST["adresa"];
    $numri=$_POST["numri"];
    $email=$_POST["email"];
    $pershkrim=$_POST["pershkrim"];
    echo $emri;
?>
</body>
</html>

When I tried to use it, it gives me this:

Notice: Undefined index: emri in G:\USB WEB Server\root\butoni\form.php on line 7

Notice: Undefined index: mbiemri in G:\USB WEB Server\root\butoni\form.php on line 8

Notice: Undefined index: adresa in G:\USB WEB Server\root\butoni\form.php on line 9

Notice: Undefined index: numri in G:\USB WEB Server\root\butoni\form.php on line 10

Notice: Undefined index: email in G:\USB WEB Server\root\butoni\form.php on line 11

Notice: Undefined index: pershkrim in G:\USB WEB Server\root\butoni\form.php on line 12 Help please? Thank you in advance.

Check your $_POST first then store the values of form `if(!empty($_POST)){ $emri=$_POST["emri"]; ..... }` — M Khalid Junaid, Nov 29 '13 at 21:07

Change your form method from:

 <form action="form.php" method="get">

to:

<form action="form.php" method="post">

also wrap the assignments in `isset()`. You'll get the undefined index values again if you visit form.php without posting to it. – Kai Qing Nov 29 '13 at 21:08
Not working. Same problem. – Enes Kristo Nov 29 '13 at 21:08
@EnesKristo same error? – Leonardo Nov 29 '13 at 21:09
Yeah. It just keeps happening – Enes Kristo Nov 29 '13 at 21:12
Is your form.php in the same route than your html file? – Leonardo Nov 29 '13 at 21:17
Indeed. Same folder, localhost and all the other needed stuff – Enes Kristo Nov 29 '13 at 21:18
Well, they have no value set in the form... – Leonardo Nov 29 '13 at 21:19
@EnesKristo do you write anything in the inputs before submitting the form? – Leonardo Nov 29 '13 at 21:24
drop the html code from the php file and try again... ` ... ` and ` – Leonardo Nov 29 '13 at 21:30
Notice: Undefined index: emri in G:\USB WEB Server\root\butoni\form.php on line 2 Notice: Undefined index: mbiemri in G:\USB WEB Server\root\butoni\form.php on line 3 Notice: Undefined index: adresa in G:\USB WEB Server\root\butoni\form.php on line 4 Notice: Undefined index: numri in G:\USB WEB Server\root\butoni\form.php on line 5 Notice: Undefined index: email in G:\USB WEB Server\root\butoni\form.php on line 6 Notice: Undefined index: pershkrim in G:\USB WEB Server\root\butoni\form.php on line 7 And this comes out – Enes Kristo Nov 29 '13 at 21:32
@EnesKristo what does this code `print_r($_POST);` displays? – Leonardo Nov 29 '13 at 22:31

You have your form on

method="get">

So in PHP you should use $_GET insted of $_POST.

Or better yet, set method to

method="post">

Because you are posting to form.php

Change your method to POST and your indexes will become valid ie defined.

Try it form.php

<?php
if(isset($_POST['emri'])){$emri=$_POST['emri'];}
if(isset($_POST['mbiemri'])){$mbiemri=$_POST['mbiemri'];}
if(isset($_POST['adresa'])){$adresa=$_POST['adresa'];}
if(isset($_POST['numri'])){$numri=$_POST['numri'];}
if(isset($_POST['email'])){$email=$_POST['email'];}
if(isset($_POST['pershkrim'])){$pershkrim=$_POST['pershkrim'];}
echo $emri; ?>

Your php code should be inside if(!empty($_POST)){} Example:

<?php
if(!empty($_POST)){
    $emri=$_POST["emri"];
    $mbiemri=$_POST["mbiemri"];
    $adresa=$_POST["adresa"];
    $numri=$_POST["numri"];
    $email=$_POST["email"];
    $pershkrim=$_POST["pershkrim"];
    echo $emri;
}
?>
