奇怪的变量/ Mysql问题

Question

I just don't know what to do, and don't know how to search about this weird problem. Here is is:

All the connection on the page are working correctly, just in case:

I Have this code to update an Email on the Database

$fUsername = mysql_real_escape_string($_GET['user']);
$fPassword = mysql_real_escape_string($_GET['senha']);
$fEmail = mysql_real_escape_string($_POST['fEmail']);

$sql = "UPDATE usuario SET email='$fEmail ' WHERE username = '$fUsername' and senha = '$fPassword'";
$result=mysql_query($sql);

Now, the Problem:

This query is not Updating the "Email" field on the BD. It just makes the field empty.

If I echo the $sql var, I get this: UPDATE usuario SET email='teste@gmail.com ' WHERE username = 'teste1' and senha = 'e10adc3949ba59abbe56e057f20f883e'

If I ran manually this query on the mySQL, it updates the field like I want.

If I manually pass a value to the $fEmail var ( $fEmail = "teste@gmail.com" ). It works just fine.

The only way that don't work is when I take the value from the Form .

Does anyone have the solution for this? D:

Answer 1

You are using $_GET for the username and password, and $_POST for the email. Check your form actual submit method, and fix the relevant data fetching.

Answer 2

You should use $_GET['fEmail'] if the form data is being sent via GET. $_POST['fEmail'] is not defined in that case, which would explain the behavior you're seeing.
