sending array with POST from a hidden input form field?

[pablo]

Dear News Groupers,

I'am trying to send a php array with a hidden input field from a form to
another script.
The array is NOT made directly by way of <input name="arrayname[]" />.

The array is made by normal php code and then
submitted between form-tags as
echo "<input type='hidden' name=\"arraynam e\" value=\"$arrayn ame\" />" ;

I can see that the receiving script receives the array but it counts only 1
item and not the presumed amount.

Can this be done?
And how should it be done then?

TIA,

pablo

Turn the array into a string and submit that

This can then be turned back into an array with

Maybe this works (not tested)

echo "<input type='hidden' name=\"arraynam e\" value=\"",
urlencode(seria lize($arrayname )), "\" />" ;

and the receiving script does

$array = unserialize($_P OST['arrayname']);

Remember that the user can change the hidden input field.
Perhaps it would be better to pass the array in a session variable.

Re: sending array with POST from a hidden input form field?

Pedro's method is quite a good way. But if you would really want it to
be safe (like if you are transferring secret US government data :P), you
could try this,

1. Generate a random string (e.g. 19235jdsnld3235 ).
2. Serialize the array you are transferring and store it in a file with
the filename generated using the random string.
OR
2. Serialize the array you are transferring and store it in a record in
a database with another field storing the random string (as an index).
3. <input type="hidden" name="arraydata " value="19235jds nld3235">
4. On the new page, just use the string to read the correct datafile or
record and Tada! you did it. ;).

This method is relatively safe as well as it will be difficult to guess
another random number. However, take good care when you store the file,
make sure you keep it in another directory or in one which is not within
the webserver root therefore increasing security.

I hope it helps :D.

And now I thank you for your quick response.

I am going to try the suggested solutions in the coming week.
