Hello all! I am new to the forums and this is my first post. I've tried to search for an answer but have come up empty handed so I thought I'd just ask outright.

 

I am building a website for a local car dealership and they want to have a "Vehicles" page where it shows a list of all the vehicles in inventory and the consumer can sort the inventory by Make, Model, Year, Color, and/or Price. I'm working with php and MySQL and I am a newbie coder trying to learn on my own. I know how to sort querys but I am completely lost when it comes to sorting with dynamic/multiple variable chosen by the user. Please help. I know my code sucks but any advise will be SUPER helpful.

 

<?php
include "storescripts/connect_to_mysql.php";
if(isset($_POST['Year'])){
$where = "WHERE";
if(isset($_POST['Color'])) {
	$and = "AND";
} else {
	$and = "";
}
if(isset($_POST['Model'])) {
	$and = "AND";
} else {
	$and = "";
}
$yearArr = "'" . implode("','", $_POST['Year']) . "'";

$yearSort = "Year IN($yearArr) $and";	
	if(isset($_POST['Color'])){
		$colorArr = "'" . implode("','", $_POST['Color']) . "'";
		$colorSort = "Color IN($colorArr)";

	} else {
		$colorArr = "";
		$colorSort = "";
			}
	if(isset($_POST['Model'])){
		$modelArr = "'" . implode("','", $_POST['Model']) . "'";
		$modelSort = "Model IN($modelArr)";	
	} else {
		$modelArr = "";
		$modelSort = "";
			}
} else {
$yearArr = "";
$yearSort = "";
$where = "";
}
if(isset($_POST['Color'])){
$where = "WHERE";
if(isset($_POST['Year'])) {
	$and = "AND";
} else {
	$and = "";
}
if(isset($_POST['Model'])) {
	$and = "AND";
} else {
	$and = "";
}
$colorArr = "'" . implode("','", $_POST['Color']) . "'";

$colorSort = "Color IN($colorArr) $and";
