[RESOLVED] Array Question

[mpar612]

I have an array question. I have a form that is generated from an array. I am curious about the most logical way to add a third value into the equation.

I am building a small app for a restaurant. Users can select the quantity that they want to order, the $key is the Item ID and the $value is the quantity. I want to add a third value that will be selected from a pulldown menu that allows the users to select how they want their meat cooked (rare, medium, etc...).

I have used the code below for the ItemID and Quantity and works great. Is there a way that I can incorporate this third value for each item?

Any guidance that will send me in the right direction would be greatly appreciated. Thanks in advance.

function process_form() {

	if(!empty($_POST)) {
		foreach($_POST as $key => $value) {
			if($key != "_submit_check" && $key != "button"  && $key != "0" && $key != "") {
				if(!empty($value)){
					$arr[$key] = $value;
				}
			}
		}	
	} 

$_SESSION['order'] = $arr;

print "<script>window.location='confirmation.php'</script>";
}

Well it's hard to tell, not being able to see your form or exactly how you process the data.

Given your situation however, I would probably set up the $_SESSION['order'] in this manner:

$_SESSION['order'][] = array('id' => $item_id, 'qty' => $qty, 'cook_pref' => $cooking_preference

In other words, each item in the $SESSION['order'] array would be an array containing those three items. You'd then use a [man]foreach/man to loop over the $SESSION['order'] array and process each triplet however you please.

Thanks for the response!

I understand your logic. I am having difficulty implementing this though.

The way I have my code setup I would want to setup the $_SESSION as follows:

$_SESSION['order'][] = array('id' => $quantity, 'cook_pref' => $temperature)

I am not sure how to make this a part of the code that I inserted in my previous post. I tried modifying based on your input (see code below), but I do not know what to do specifically with the foreach(). I have the $key => $value, but I also need to add the $cooking_pref => temperature in order to populate the array.

Any thoughts would be greatly appreciated. Thanks!

[code=php]function process_form() {
	if(!empty($_POST)) {
		foreach($_POST as $key => $value) {
			if($key != "_submit_check" && $key != "button"  && $key != "0" && $key != "") {
				if(!empty($value)){
					//$arr[$key] = $value;
					$_SESSION['order'][] = array($key => $value, $cooking_pref => $temperature);
				}
			}
		}	
	} [/code]

I am not sure if this is relevant now, but here are all of the fields in my form:

<input name = \"$itemId\" value=\"$quantity\" size=\"3\" />
<select name=\"temperature\">
	<option>-- Select --</option>
	<option>Blood-Rare</option>
	<option>Medium-Rare</option>
	<option>Medium</option>
	<option>Medium-Well</option>
	<option>Well</option>
</select>

You are not setting any values for the select options.

For example:

<option value="br">Blood-Rare</option>
<option value="mr">Medium-Rare</option>
<option value="m">Medium</option>
<option value="mw">Medium-Well</option>
<option value="w">Well</option>

Thanks for catching that!

Any thoughts on the foreach() loop?

Thanks!

Sorry, I'm not entirely sure what you need to accomplish. I think your original method will work fine now that the 'temperature' key is passing a value.

The best way to figure out how you need to loop an array is to print it..

print_r( $Array );
