The question is simple

But I'm kinda a newbie so I'm gonna try to tell what's the problem and why i ask this

I'm doing a login system than, for different users showing different services, and until the moment all the login process has successfully ended just fine and works perfectly, BUT:

some of this services (i.e. File uploading) i wanna add include the use of a form, the forms are HTML, and the "session_start()" are PHP like all of you must know, so this is the question.

(already try with echo/print, btw)

Is there any way to add a form (html based) inside a PHP script to actually works depending of if it's working or not the session_start()?

With the "Session_start()" i mean if he is or not log-in Have in mind that the service is gonna be used by the person who login

Here is the code

PHP Code:
<?php
session_start();
echo $_SESSION['username'];
echo $_SESSION['name'];
echo $_SESSION['test'];
if ($_SESSION['class'] === 7){
print '<html><form action="upload.php" method="post" enctype="multipart/form-data"><br /><input type="file" name="info" /><br /><br /><input type="submit" value="Subir" /></form></html>';
} elseif ($_SESSION['class'] === 7 or 2) {
echo "también esto se muestra";
} elseif ($_SESSION['class'] === 7) {
echo "esto también";
} elseif ($_SESSION['class'] === 7) {
echo "esto también";
}


Thanks in advance
