PHP/Mysql search engine

I have a php script that runs a search engine for old cars and parts on my site and I need to add a picture upload that corralates with the item that the people search for. So when the search locates and item in the database there will be a picture associated with the search item.
the url for the search page is here http://hp-car.com/cars/index.php

Thank you

Good. You have two ways to do it, but for both ways you first need to learn very well this page:
http://www.php.net/manual/en/features.file-upload.php

After that, you choose wether to insert the picture to the database, or to store it on your local HD with some kind of indexed numbering.
The easiest way is to store the uploaded image in a dedicate directory with a name like car1.jpg, car2.jpg.. where the number is the row id of your matching database entry (you have an auto_increment field, do you?).
That's all i think..

Actually I think you are looking to have a picture display with the link you call up? not have a user upload a picture to the item they search for.

In that case what you really need to do is this:
In your MySQL database add a field to your item list that is searched called 'picLinks' then put the file location of the file there.

In your php/HTML script

you would have something like
<img src=<?php "/"". $itemdb["picLinks"] ."/"" ?>>

This way you don't need to have a file naming standard for the images you upload and so forth.
I think this what your asking for if I understand your question correctly.

Hope this helps, have fun coding!

Merge both the suggestions of ThG (for the uploading part) and red010knight (for Link to image)

Just a question.....how many images do you need of each particular item? one, or more than one

do NOT store files in your database!! it will cause a huge load on the database wich almost all databases can't handle.
It's a much better idea to store the files in some folder and put a reference to that file in your database.

except from storing files in the database I completely agree with the suggestions made to do what you need.

What I don't know is where to modify the code I have, I don't know if I should add the code here or to the other php script.

<?php
$usr = "dcatkin";
$pwd = "hellfire";
$db = "cars";
$host = "localhost";
$cid = mysql_connect($host,$usr,$pwd);
mysql_select_db($db);
if (!$cid) { print "ERROR: " . mysql_error() . "\n"; }
?>
<?php
$Make = $_POST["Make"];
$Year = $_POST["Year"];
$Model = $_POST["Model"];
$Price = $_POST["Price"];
$Description = $_POST["Description"];
$Name = $_POST["Name"];
$Address = $_POST["Address"];
$Email = $_POST["Email"];
$Phone = $_POST["Phone"];
$URL = $_POST["URL"];
$pclinks = $_Post["picLinks"];
if ($_SERVER['REQUEST_METHOD'] == "POST") {
$sql = " INSERT INTO Cars ";
$sql .= " ( Make, Year, Model, Price, Description, Name, Address, Email, Phone, URL, pclinks) VALUES ";
$sql .= " ('$Make', '$Year', '$Model', '$Price', '$Description', '$Name', '$Address', '$Email', '$Phone', '$URL','pclinks') ";
$sql = " INSERT INTO Cars";
$sql .= " ( Make, Year, Model, Price, Description, Name, Address, Email, Phone, URL, pclinks) VALUES ";
$sql .= " ('$Make', '$Year', '$Model', '$Price', '$Description', '$Name', '$Address', '$Email', '$Phone', '$URL','pclinks') ";
$result = mysql_query($sql, $cid);
if (mysql_error()) { print "Database ERROR: $sql " . mysql_error(); }
print "<br>";
print "<br>";
print "<center>";
print "<B>";
print "New Car Added";
print "<br>";
print "<br>";
print "<center>";
print "<B>";
print "Thank you for adding your car to our database";
print "<br>";
print "<br>";
print "<center>";
print "<B>";
print "Come back often.";
}
?>

<?php
   session_start();
   mysql_connect("localhost", "dcatkin", "hellfire")
     or die("(".mysql_errno().") Error:".mysql_error());
   mysql_select_db( "cars" )
     or die("(".mysql_errno().") Error:".mysql_error());

you need to modify both the submit form and this file.
In the form you add the well-known file input html tag. Here you'll need to handle the file uploaded, whose record is in $_FILES as shown in the link i gave you, at the top where it handles other $_POST data as well.
