PHP $_SESSION on form submit lost

Question

I'm lossing the session when I submit a form, until them I kept loged in my code.

I'm sending the session values through the form in that way, but it does not work at all:

<input type='hidden' name='loged' value='".$_SESSION["loged"]."'>
<input type='hidden' name='role' value='".$_SESSION["role"]."'>

Is that right?

Thanks you

of course before I get loged, I alredy worte this on the code:

session_start();

Why do you need to put session data into form inputs? Why can't you just read it from $_SESSION? — No Results Found

to set the value try using "<?php echo $_SESSION['loged']; ?>" — Drewdin

If you lose the session data, you're most likely doing something wrong. Can you post a short example to reproduce what is happening? — phant0m

is this part of html code,or php? could you post a little more code? — Paris Liakos

Ok, the main problem is that I lost the session when I execute the submit, but not when I execute a link that point the same place... the main reason I need to use the submit is because when I click the link I execute an specific sql query, and when I do the submit I execute the query but passing what I want to look in the query. If I do so passing the parameter through a link in that why index.php?param=value it works well, but when I execute the submit I get loged out... — unkown

wrong way, you don't need to submit values already set in session

But My problem is that when I submit the form I lose the session, but if I do anything else, for example, passing parameters through the URL I kept logged.

Here it goes: if($_SESSION["logged"] == "yes" and $_SESSION["role"] == "admin" ){ echo" <form method='post' action=''> <div class='search'> <input type='text' style='color:#f65656' name='char' value=''> </div> <div class='search_submitbox'> <input value='サーチ' type='submit' id='search'> </div> <input type='hidden' name='logged' value='".$_SESSION["logeado"]."'> <input type='hidden' name='role' value='".$_SESSION["role"]."'> </form>";

1) remove hidden inputs - 2) add action="your_url" to your <form tag - 3) before you execute search query, check your session values to know if user is allowed - 4) all your scripts must have session_start() to not lose session

You are submitting the form ... if you do a phpinfo(); you'll see that the inputs have now arrived as value under $_REQUEST ... If you want to access the session variables again, you need to:

session_start();
print_r($_SESSION);

You'll see your session vars again.
