Putting Form Contents into an Array

[lobley]

This is the first time I have been stuck like this.

I am using a shopping cart that uses arrays as session variables to hold all the users products. I am trying to create a page that lists all the products so repeat shoppers can just put in the quantities to order. To make use of the existing check out page (displays all the order info) I need to put these values into the arrays. When the values are put in and the user submits the page how can I put these values into an array? If anyone can help I would apreciate it.

Gerry,

You can use this:

http://www.php.net/manual/en/function.serialize.php

And save the data in a row in the database, and pull it out... I would not do it this way...but.

I dont't have a problem passing the array, the problem I have is putting the values from the form into an array. The form is dynamic and might change. I guess I need a loop to push it into an array but it needs to be built on the fly and thats what I can't do.

look at HTTP_POST_VARS, HTTP_GET_VARS, or GLOBALS, maybe have some hidden fields.

Gerry:

If you need the variables in an array php will support the following. As an example generate HTML code in the following fashion

<input type="text" name="userinput[input][1]">
<input type="text" name="userinput[input][2]">
<input type="text" name="userinput[input][3]">
<input type="hidden" name="userinput[hidden][1]" value="hiddenvalue">

When this page is posted you will have the following array defined in your variable table

$userinput

it will have two indexes
"input"
"hidden"

$userinput["input"]
will have three elements with indexes
"1"
"2"
"3"
$userinput["hidden"]
will have one element with index
"1"

This is done automatically with no user input or parsing, the importance is placed on the name used for the input field on the page.

Hope it helps
