Return an array index's name???unique problem

[rwfresh]

Hi all,

 I am working with project that uses array index's as form names ie:

<input type=text name="id[txt_1]" >

It does this so the $HTTP_POST_VARS becomes a multidimensional array:

$HTTP_POST_VARS['id']['txt_1'] = "posted value";

post looks like this: Array ( [id] => Array ( [txt_1] => asdfasdf [txt_2] => asdfasdf [4] => 1 ) [quantity] => 1 [terms] => 0 [products_id] => 69 [x] => 16 [y] => 17 )

My problem is this. These input names are generated based on values from a MySQL table. Some of the values on the form end up being dates the end user must select. I want to be able to use a javascript popup calendar inside the form but unforetunately cannot pass the input names (as required by the js calendar) to the js script because they are array formatted.

One solution i have come up with is to rename these input names to none array formats. ie: txt_1, txt_2, txt_3 etc. and then immediately after the post i will rebuild the array with the correct indexes... I hope this makes sense.. but what i want to do is

change

this:

$HTTP_POST_VARS[txt_1]

to this:

$HTTP_POST_VARS['id']['txt_1']

after the post.

Obviously it's all dynamic so i can have as many date fields on the form as i want and they will all be changed to the correct index and have the values carried with them..

Please help... any other better ideas are GREATLY appreciated!

<?
$arr['id'] = array();

while(list($key, $val) = each($_POST))
{
     $arr['id']['$key'] = $val;
}
?>

may work... if not....

<?
$arr['id'] = array();

while(list($key, $val) = each($_POST))
{

 $arr['id'][] = "$key => $val";
}
?>

possible alternative....

Along with the date fields there are a bunch of other fields being sent with the Post.. what would be the fastest to determine which to convert? ie: which $keys of the $_POST start with txt ??

Thanks alot!

if (substr($key,0,4) == 'txt_')
{
     //array code from earlier here
}
