You may want to provide a little more info so that a better example can be tailored to your situation, but let's say you have an array on a page that needs to be submitted to the next one and you are using a hidden form field to do this. You can just use the implode function (http://www.php.net/manual/en/function.implode.php) to convert the array to a character delimted string and pass that in the hidden form field and on the next page just use explode (http://www.php.net/manual/en/function.explode.php) to extract the contents back into an array.

Also, you may opt to just use a session variable instead of a form field depending on what you are trying to do.

Hmmm ... Some time ago I've encountered with the following problem: I was needed to generate a page that collects data from the user in variable number of input boxes and then passes all that data to the next page for processing ...

I could easily do naming of the input boxes on the first page. So ideally it looked like creating an array of input_boxes[] and giving all input boxes on the first page names like input_box[1], input_box[2], input_box[3] and so on. And then easily process all data using this array. But, HTML forms seems to be forbidding passing array data ... Or am I wrong?

P.S.: I've solved the problem using a loop that automatically creates different names for every input_box on the page: input1, input2, input3 .... But of course if I could use array variable instead that would be much more comfortable with further coding ...

If you're talking about arrays for form text input fields you may want to look at variable variables http://www.devshed.com/Server_Side/PHP/VarVar/page1.html .

Yep, variable variables is what I used in my solution ;). But I still dreamed if it could be possible to use something like:

<form action="processing.php">
<input type="text" name="array[1]">
<input type="text" name="array[2]">
..........
<input type="submit">
</form>

And then accessing data from these field in processing.php like $array[1], $array[2] ... But it's not possible and the only solution is using variable variables for processing all input boxes (naming them input1, input2 ...), right? :rolleyes:
