$_POST problems

aubeasty

Hi There,

I upgraded PHP from v4.0.x to v4.2.3 recently and some of my 'old' PHP files no longer work correctly. I had a poke around the site and it seems some of the predefined variables have changed.

Can someone please tell me the correct way to use the values from $_POST?

As an example, during one of my tutorials, this INSERT used to work, now it doesn't -

$sql = "INSERT INTO employees (first,last,address,position) VALUES ('$first','$last','$address','$position')";

So, I tried the following (which looks correct according to the php editor I used....)

$sql = "INSERT INTO employees (first,last,address,position)VALUES ('" . $POST['first'] . "','" . $POST['last'] . "','" . $POST['address'] . "','" . $POST['position'] . "')";

Results - I'm not getting anything put into my table.

Any help would be appreciated!

if you want,you can modify the "php.ini" file,here is how:
register_globals=on;
then $sql = "INSERT INTO employees (first,last,address,position) VALUES ('$first','$last','$address','$position')";
the clause can work;

if you don't want to set register_globals,you have to enable
the track_vars=on;
then
$sql = "INSERT INTO employees (first,last,address,position)VALUES ('" . $POST['first'] . "','" . $POST['last'] . "','" . $POST['address'] . "','" . $POST['position'] . "')";
this clause can work;

if you don't want to do anything to php.ini
you can use
$HTTP_POST_VARS['rirst']

etc.etc

Hi slshmily,

FYI, I went to modify the php.in file and came across this:
;;;;;;;;;;;;;;;;;
; Data Handling ;
;;;;;;;;;;;;;;;;;
;
; Note - track_vars is ALWAYS enabled as of PHP 4.0.3

So, no need to worry about this one.

I don't want to set register_globals off because my test environment won't mirror the production environment.

I will try the older $HTTP_POST_VARS['first'] instead and see how I go.

Cheers,

Andrew

When the variables are passed from one page to another they are placed in the array $_POST. So you want to access those vaiables huh?

Try

extract($_POST);

Extract is a built-in php function

Keep in mind that $POST only works if the variables were actually POSTed. 'aubeasty' s problem could be that the variables are being provided with the GET method. In this case $GET or $_RESULT would be needed.
