you have some html error it should be like <input type="text" class="form-control" id="nickname" placeholder="Nickname" name="nickname" /> </div> — Samundra Khatri

For a debug session, you can replace the form method with GET so that you can see visually what gets submitted exactly.. — Mr Lister

Several things, your HTML is invalid (though I'm not sure it's breaking it) please use appropriate type values in your input fields. For name and nickname, the valid type value is "text", not "name" or "nickname" those belong as values of the name and id tags for those inputs.

Using isset will be true even if the variable is an empty string, because the $_POST variable will have that variable, just probably empty so isset passes, you want to check for an empty string I think (use empty() for that)
