HIDDEN input type and arrays

[[deleted]]

Hallo guys,
is it correct to pass from a script to another an array type variable inserted in a hidden field, that's to say :

<input type="hidden" name="userData" value="<?php echo("$userData"); ?> ">

where $userData is an array.

If so, is it the correct syntax ?
I have problems accessing the array in the following script...

Thanx to all
Roberto

No, it's not. When you do echo($Array), it only shows the word <B>'Array'</B>.

Do this:

$NumElem = count($Array);
for($i=0;$i<$NumElem;$i++){

echo "<INPUT TYPE=\"HIDDEN\" NAME=\"hid_field[$i]\" VALUE=\"".$Array[$i]."\">\n";

}

This way you create one field for each element on the array.

Hope this helps

Thank you fLIPIS
I didn't kno that arrays cannot be passed as hidden.
And yur suggestion is OK, but my problem is, that my array is an array of arrays !

So I think it'd be easier to figure out some
other way to preserve that data...

Bye,

you could add some recursion to fLIPIS's idea to echo out all of the hidden array and sub-array elements or a much more elegant approach would be to use sessions.
