[SOLVED] Filter values in multidimensional array?

[easyedy]

Hi I'm trying to filter my multidimensional array based of the ID passed. I'm almost there but I missed a step somewhere. Here is the code below when I try to filter the array by ID =1 ie: product.php?id=1

 

Array
      (
          [brand] => Array
              (
                  [Type] => Array
                      (
                          [0] => Array
                              (
                                  [iD] => 1
                                  [Name] => Plus
                                  [size] => XL
                                  [Price] => 100


                              )
                          [1] => Array
                              (
                                  [iD] => 3
                                  [Name] => Shox
                                  [size] => XL
                                  [Price] => 100


                              )
                          [2] => Array
                              (
                                  [iD] => 2
                                  [Name] => Zoom
                                  [size] => XL
                                  [Price] => 100


                              )

                          [3] => Array
                              (
                                  [iD] => 1
                                  [Name] => Plus
                                  [size] => XL
                                  [Price] => 100


                              )

                      )

              )

      )

function array_filter_multi($input, $filter="", $keepMatches=true) {
        if (!is_array($input))
                return ($input==$filter xor $keepMatches==false) ? $input : false;
        while (list ($key,$value) = @each($input)){
                $res = array_filter_multi($value, $filter,$keepMatches);
                if ($res !== false)
                        $out[$key] = $res;
        }
        return $out;
}


$newArray = array_filter_multi($result['Brand']['Type'], $filter= $_GET[id], $keepMatches=true);

print_r($newArray);

 

 

Gives me the output of:

 

Array ( [0] => Array ( [iD] => 1 ) [1] => Array ( [iD] => 1 ) )

 

It's just giving me the ID's and not the full array with ID, Name, Size, & Price...

 

Any thoughts? Thx

Well, without your code, its pretty difficult to tell you whats wrong with it. However, i put this together which i think will do what you're after (and possibly more):

 

<?php
$array = array('Brand'=>array('Type'=>array(array('ID'=>1,'Name'=>'Plus','Size'=>'XL','Price'=>100),array('ID'=>3,'Name'=>'Shox','Size'=>'XL','Price'=>100))));
function find_items($array,$findwhat,$value,$found=array()){
foreach($array as $k=>$v){
		if(is_array($v)){
		 	$result = find_items($v,$findwhat,$value,$found);
			if($result === true){
				$found[] = $v; 	
			}else{
				$found = $result;
			}
		}else{
			if($k==$findwhat && $v==$value){
				return TRUE;
			}
		}
}
return $found;

}
$found = find_items($array,'ID',1);
echo '<pre>'.print_r($found,1).'</pre>';
?>

 

This will allow you to search for any product where the attribute matches what you're after. So, in the above example, we can search for a product where the ID is 1. Or, we could search for all products where the size is XL, using:

 

$found = find_items($array,'ID',1);
echo '<pre>'.print_r($found,1).'</pre>';

 

If this isn't what you want, please explain a bit more fully. And post up the code you've got currently.
