Wordpress: Multiple select values

[adige72]

Below code is what i found from a search in web.

 

Suppose i have a taxonomy called Color and terms are Blue, Green, Red, Yellow, White. I want when i select Blue, Green and Red and click submit button, i want to get ALL posts those have Blue OR Green OR Red (OR etc.) taxonomy term on the search results page.

 

Since the code below is just echoes "Insert Query - Blue, Insert Query - Red ...", is there any way to convert this into a code that in which i can get posts?

 

Thanks in advance.

 

 

<?php
if(isset($_POST['clickhere'])) {
$selected_values = $_POST['color'];
foreach($selected_values as $key=>$value) {
                // Insert query comes here.
	echo "Insert Query - ".$value."<br />";
}

$select_blue = (in_array('1',$selected_values)) ? "selected" : "";
$select_green = (in_array('2',$selected_values)) ? "selected" : "";
$select_red = (in_array('3',$selected_values)) ? "selected" : "";
$select_yellow = (in_array('4',$selected_values)) ? "selected" : "";
$select_white = (in_array('5',$selected_values)) ? "selected" : "";
}
?>

<form name='testform' action='sometest.php' method='post'>
<select name='color[]' style="border:0px;" size=6 multiple>
