checkbox help

[KashKurcura]

am trying to build up the contents of an array so that i can store the final result into mysql. below i have sample checkboxes and the final result that i need to store. i am sure i can do this with a simple loop but i would end up with 'red','green','blue', as a result and not 'red','green','blue' like i need.

anyone have any suggestions?

<form method="get" action="test.php">
<input type="checkbox" name="colors[]" value="red" /> Red
<input type="checkbox" name="colors[]" value="blue" /> Blue
<input type="checkbox" name="colors[]" value="green" /> Green
<input type="checkbox" name="colors[]" value="yellow" /> Yellow
<input type="submit" name="go" value="go">
</form>

<?php

if($colors) {

foreach ($colors as $key=>$value) {

echo "'{$colors[$key]}',";

}

}

?>

Okay.. first of all, you should be using $_GET['colors'] instead of $colors. If $colors works, then register_globals is turned on and you should turn it off.

Next... I don't know if you've read up on how [man]foreach/man loops work, but basically they iterate through the array and pass each key and value (or just value, depending on how you structure the loop) to the loop. In other words, you really don't use $colors inside your loop at all - all you need is the $value. Since you don't even need the index key, you could actually rewrite this as:

foreach($colors as $value) {
// stuff you want to do with the value here
}
