losing $HTTP_SERVER_VARS

happyme

Hi there,

I have a script that was working very well until I introduced $HTTP_SERVER_VARS.

It's very long so here's what it does:

It displays the contents of a MySQL table, giving the user the option to edit each item. The edit returns the user to the same page to complete a form which also returns to the same page.

The script identifies what it's required to display by the contents of the $id string which is set depending on the actions of the user.

That all works fine.

I thought it would be useful if the MySQL table recorded who had last altered or entered a particular piece of data, without trusting people to fill in their names. The page is in a secure part of the site.

The script welcomes the user to the page by name which works fine using:

$yourname = ucwords($HTTP_SERVER_VARS["REMOTE_USER"]); and echoing $yourname at the appropriate point.

I then try to use $yourname after the user has entered data which is submitted using a form (on the same page) which includes:

as soon as they hit the submit button, $yourname is lost.

how can I keep this variable?

Try $_SERVER['REMOTE_ADDR']

theres no such thing as REMOTE_USER either

there must be such a thing as REMOTE_USER or it wouldn't obligingly return my name when I use it...

I might be wrong on this but I think if you do <?php echo phpinfo() ?>, it will tell you what are the reserved variables for php.

yes, that was how I found
$HTTP_SERVER_VARS["REMOTE_USER"]
in the first place.

The above works very well, my problem is the variable $yourname loses its value when the form is returned to the page

Where is your form's action sending it to? Another PHP page? If you need the value of $yourname to be made available on another page, consider using session variables...

if you are posting to yourself, then check to see that $yourname is called again when you reenter...

I'm posting to the same page

this is this bit of code it encounters when the form has been submitted. This all works except $yourname has lost its value

if ($submit) {

// here if no ID then adding else we're editing

if ($id) {

$sql = "UPDATE $tablename SET headline='$headline', blurb='$blurb', addy='$addy', email='$email',		appby='$yourname', approved = '$approved' WHERE id=$id";

}
