dynamic NAME using POST

asolell

Hi All,

I'm creating a form dynamically. Easy enough.
In the creation, I pass an array that contains the value of the names:

$SourceFieldListNoPrimary[0]
$SourceFieldListNoPrimary[1]
$SourceFieldListNoPrimary[2]
$SourceFieldListNoPrimary[3]

Well.. that translate nicely into:

etc etc...
So this is using a POST.. I need to grab the Inventory_Item_Description on the next page.
How do I do that??

I need to be able to have a $Inventory_Item_Description variable waiting on the next page so it will hold the value..but I don't know how to pass it.
I mean,. of course I can create a Hard coded $Inventory_Item_Description variable... but that won't serve my purpose.
I want to have that variable passed 'Inventory_Item_Description'
and have a '$' sign attached to it to make it a variable.
How do I go about doing that?

Appreciate your help on this.

$_POST['Inventory_Item_Description']

.. to access it.

I'm affraid that doesn't do the trick.

I thought it over and I prob need to rephrase my question into:

Take a value in an Array and turn it into a variable.

How do you do that?

$SourceFieldListNoPrimary[0] = Item_Inventory_Description;

Now,. on the next page:

How do you retrieve $Item_Inventory_Description

and it needs to be dynamically. No hard coding of the

Item_Inventory_Description.

So I can't use:

$_POST['Inventory_Item_Description']

Basically I need a mechanism to have a variable that holds other variable names within it and the ability to access those variables.

I think it is similar to a struct() or something like that, but I've never done it.. so I could use some help here.

Still not quite sure what you are looking for, but here goes...

$POST is simply an array, with each key representing a variable from the previous page. As such, array_keys() will return an array of all of the keys of $POST.

Therefore, if $_POST contains:

['action'] => "save"
['id'] => "56456563"
['stuff_to_change'] => array(
    '0' => 7
    '1' => 13
    '2' => 27
    )

array_keys ($_POST) would return an array containing "action", "id", and "stuff_to_change".

Hope this is on the right track.

If not, well... I probably needed to look up this function anyway.
