HTML Form POST is null

Question

so I'm trying to simply send one field of data from a form to a php file. Below is my form in a table. I also posted my php code. It keeps returning that $username is null. Ive tried post/get and it doesn't seem to matter. HTML: ``` ``` PHP: ``` ```

Accepted Answer

This code is working. You need to add some condition, that checks, if `$username` is posted or not.

Something like that:

```
if(count($_POST)){
    $username ='';
    if(isset($_POST['user'])){
        $username = $_POST['user'];
    if ($username==null || !$username)
         echo 'username is null';
     echo strlen($username);
     echo $username;
   }

}
```
