New to php $_post query

spelbound

Hey all. I'm learning php in my own time and am doing fairly ok.

What I have done is create an XHTML page with a form that submits to a php file. The forum provides 10 input boxes and submits that data. That side of it is solid and works fine, but I need help with the php file.

How do I take that data and output to a table on the php page. I know I need to use an array and the $_post function but...I'm struggling. If I write out an array manually on the php page I can output to the table no problem...I just dont know how to get that data from the submited form :-( I think once I see a good example I'll understand it all.

Help a struglling code junkie wouldya?

use the $_POST method to retrive the data

thanks for replying. As I said, I know thats what I need to do, I'm just not sure how the code should look.

I know how to post to a variable e.g.
$_POST[‘something'];

and I know how to create an array e.g.
$sale= array(

"Toothbrush" => "discounted",

"Shaver" => "discontinued",

"foam" => "standard"

);

...what I'm not sure of his how the $_POST and array fit together.

$_POST is an array, not a function. When you submit your form (that uses the POST method), all of the form input values will be in the post array, indexed by their names (HTML name attributes).

Thanks.

So, I did this as a test and it works:

$shopper= $_POST["shopperId"];
echo $shopper;

I now want to input that (and the other 'fields') into a table.

Since $_POST is an array I assume it has been assigned a key (shopperId?) and how can I make use of that?

Many thanks in advance again.

Each element in the $POST array is referenced by its index, which correspond directly to the name attributes of your form elements you gave in your form. For example if you had a name field with the name "fname" and a value of "bob" then your $POST variable would have a $POST['fname'] which would contain "bob". From here you can echo the values or do whatever you need.

Though when working with posted data, make sure it has a value with isset or empty.
