Thanks everyone, I'm getting closer. The only problem I have not is that
I keep entering that test, I modified it to change the session variable
once we enter the test but it somehow does not seem to change it? This
is the code,
if(strlen($_SESSION['loggedin']=="yes")){
$_SESSION['loggedin']="no";
$CONTENT = "You are currently logged in as ".$_POST["username"].
"<form action=\"index.php\" method=\"POST\">
<input type=\"submit\" value=\"Log out\" />
<input type=\"hidden\" name=\"logout\" value=\"yes\"/></form>
<hr>If you would like to change the text on the main page please click
here <a href=\"index.php?action=edit\"><font color=\"blue\">Edit intro
page</a><font color =\"#136863\"><hr><h3>File Upload.</h1><hr> Any files
will appear in the 'students' page of the website. Files that uploaded
here are not availablre to the public and can only be acccessed by
students who have logged in. Because of security issues only well know
file types such as word, acrobat and text files are legible for upload.
<form enctype=\"multipart/form-data\" action=\"index.php\" method=\"POST\">
<!-- MAX_FILE_SIZE must precede the file input field -->
<input type=\"hidden\" name=\"MAX_FILE_SIZE\" value=\"30000\" />
<!-- Name of input element determines name in $_FILES array -->
Send this file: <input name=\"userfile\" type=\"file\" />
<input type=\"submit\" value=\"Upload\" />
<input type=\"hidden\" name=\"arg1\" value=\"yes\">
</form>";
}
When I click the logout button it works fine, but when I click on the
link inside the page it simply reloads the same page as if the session
variable has not changed at all? If I link to a page like this does it
call the script again, or does this need to be done with a form submit?
I must apologise for my lack of knowledge here! I program in other
languages and as a result I have that I can get really deep in code I
don't understand very fast!
