php / ajax variables

[driveflexfuel]

I am a little lost when it comes to MySQL and ajax. I have been trying to figure this out for a few hours and I am hoping someone here could give me a hand. I am working with the code below that was given to me by fellow site owner. At the bottom of the code i need $sendlink to = the link pulled from the database. 400 Credits to the person with the solution

<?php
include 'config.php';

$link = mysql_connect($servername,$user,$pass);
if (!$link) {
   die('Could not connect: ' . mysql_error());
}
mysql_select_db($db);

function setyear()
{
global $table;
   $make='';
   $query = "SELECT DISTINCT acura from $table where year=".$_REQUEST['year'];
   $result = mysql_query($query);
   if (!$result) {
      $message  = 'Invalid query: ' . mysql_error() . "\n";
      $message .= 'Whole query: ' . $query;
      die($message);
   }
   while ($row = mysql_fetch_assoc($result)) {
   $make = $make.$row["acura"].'|';
   }
   
   echo $make;die();
}
function allyear()
{
global $table;
   $year='';
   $query = "SELECT DISTINCT year from $table ORDER BY year";
   $result = mysql_query($query);
   if (!$result) {
      $message  = 'Invalid query: ' . mysql_error() . "\n";
      $message .= 'Whole query: ' . $query;
      die($message);
   }
   while ($row = mysql_fetch_assoc($result)) {
      $year = $year.$row["year"].'|';
   }
   
   echo $year;die();
}
function setmake(){
global $table;
$model='';
   $query = "SELECT DISTINCT model from $table where year="."'".$_POST['year']."'"."and acura="."'".$_POST['make']."'";
   
   $result = mysql_query($query);
   if (!$result) {
      $message  = 'Invalid query: ' . mysql_error() . "\n";
      $message .= 'Whole query: ' . $query;
      die($message);
   }
   while ($row = mysql_fetch_assoc($result)) {
      $model=$model. $row["model"].'|';
   }
   echo $model;die();
}
function setmodel()
{
global $table;
$cylinder='';
   $query = "SELECT  DISTINCT cylinder from $table where year=".
   "'".$_POST['year']."'"." and acura="."'".$_POST['make']."'". " and model="."'".$_POST['model']."'";
   $result = mysql_query($query);
   if (!$result) {
      $message  = 'Invalid query: ' . mysql_error() . "\n";
      $message .= 'Whole query: ' . $query;
      die($message);
   }
   while ($row = mysql_fetch_assoc($result)) {
   $cylinder=$cylinder.$row['cylinder'].'|';
   }
   echo $cylinder;die();
}

function gourl(){
global $table;
$query = "SELECT link from $table where year=".
   "'".$_POST['year']."'"." and acura="."'".$_POST['make']."'". " and model="."'".$_POST['model']."'"
   . " and cylinder="."'".$_POST['engine']."'";;
   $result = mysql_query($query);
   if (!$result) {
      $message  = 'Invalid query: ' . mysql_error() . "\n";
      $message .= 'Whole query: ' . $query;
      die($message);
   }
   $row = mysql_fetch_assoc($result);
   $link = $row['link'];
   return $link;
}
if (array_key_exists('option',$_GET)) {
if ($_GET['option'] == 'setyear') 
{
   setyear();
}
if ($_GET['option'] == 'setmake') 
{
   setmake();
}
if ($_GET['option'] == 'setmodel') 
{
   setmodel();
}
if ($_GET['option'] == 'allyear') 
{
   allyear();
}
}

if (array_key_exists('go',$_POST)) {
   if ($_POST['go']=="SendQuery")
   {
      $year = $_POST['year'];
    $model = $_POST['model'];
    $make = $_POST['make'];
    $engine = $_POST['engine'];

    $sendlink = HELP ;

      //$data = substr($data,0,strlen(data)-1);
      $link = gourl();
      $link = basename($link);
      $fulldir ="/home/e85and/public_html/TEST/store/";
      include($fulldir.$link);    
      die();
   }
}
?>

Your answer would be

$sendlink = gourl();
