[RESOLVED] Problem passing a form variable

[bt23]

Hi,

I basically have a form that passes form element variables. Simple enough, but, one of them is a select box. The options inside are more or less child/parent related (nodes, if you will) and can branch many many levels deep.

I can generate these fine, for example:

My Cat -> this value is "6" (basically, cat id 6)
- My Sub Cat (basically, cat id 7)
- My Sub Cat 2 (basically, cat id 8)
- - Child sub Cat Of above (basically, cat id 9) <-- here is a problem. I need to pass the parent also, like this:

<option value="8&view=9">- - Child of cat of above

Basically, if the option is a child of a parent I need to pass the standard cat id, but also the child id. This is easily done, like here (this is an actual copy/paste of the ids/names so if they don't make sense don't mind them):

<option value='14'>Amulets & Rings
<option value='14&view=87'>- Rings
<option value='14&view=96'>-- Bul-Kathos
<option value='14&view=102'>-- Carrion Wind
<option value='14&view=101'>-- Dwarf Star
<option value='14&view=100'>-- Nagel Ring
<option value='14&view=99'>-- Natures Peace
<option value='14&view=98'>-- Raven Frost
<option value='14&view=95'>-- Stone of Jordan
<option value='14&view=97'>-- Wisp Projector
<option value='14&view=86'>- Amulets
<option value='14&view=93'>-- Atmas Scarab
<option value='14&view=91'>-- Highlords Wrath
<option value='14&view=88'>-- Maras
<option value='14&view=90'>-- Metalgrid
<option value='14&view=89'>-- Seraphs Hymn
<option value='14&view=92'>-- The Cats Eye
<option value='14&view=94'>-- The Rising Sun
<option value='9'>Annihilus
<option value='9&view=60'>- Unidentifed

Now, passing root parents (ie, Amulets & Rings, cat #14) works fine as you'd expect. I was under the assumption I could pass and amp and another value and it would set too. I guess not, the output is actually:

/browse.php?rid=1&type=1&cat=14%26view%3D100&mode=image&display=asc&show=20&page=1

My ideal result is...

/browse.php?rid=1&type=1&cat=14&view=100&mode=image&display=asc&show=20&page=1

Is this possible to do in pure PHP without using a hidden form element? I know that'd probably be the simplest way, but I know this works fine in pure JS (ie, using an onClick and grabbing the index array of the select options. I tried also using the &amp and such but to no avail; yeilding the same result.

Thanks

[execute]

&amp; doesnt work ? hmm then why dont you just send
try urldecode(); your values.
If not, submit all your IDs as
14100blablabla then use explode("*", $cat);
and get an array of the values.

Hi,

None of that worked, I tried many variations before posting here (this was a last resort...).

I ended up writing a mock/hack of extract() to pre-parse and look for 1 var being assumed as 2 (or multiple). I know someone might have this problem later, so here's my code if it helps anyone with a similuar situation.

function xextract ($array,$mode = EXTR_OVERWRITE)
{
	if (sizeof($array) == 0)
		return;

$tmp		= array();

foreach ($array as $key => $value)
{
	//check if value has a & in it, if so, break it open and make a X new keys 

	$args	= explode("&",$value);
	$sizeof	= sizeof($args)-1;

	if ($sizeof > 0)	// we have multi args
	{
		//always set the first array since it's parsed out of pattern

		$GLOBALS[$key]			= $args[0];

		for ($ctr = 1; $ctr <= $sizeof; $ctr++)
		{
			$temp				= explode("=",$args[$ctr]);
			$GLOBALS[$temp[0]]	= $temp[1];
		}
	}
	else				// normal arg
		$GLOBALS[$key]			= $value;
}

//array_die($tmp);
}

xextract($_GET,EXTR_OVERWRITE);
xextract($_POST,EXTR_OVERWRITE);

.. Enjoy.
