Storing Images In MySQL
Displaying The Image
Now we have the ability to get the images into the database, we need to be able to get it out.
Here we see a simple script to display an image based on its image_id in the database. Of course you should do more checking on the value of $_GET['image_id'] here. We will call this file view.php.
Listing 6 file.php
// just so we know it is broken error_reporting(E_ALL); // some basic sanity checks if(isset($_GET['image_id']) && is_numeric($_GET['image_id'])) { //connect to the db $link = mysql_connect("localhost", "username", "password") or die("Could not connect: " . mysql_error()); // select our database mysql_select_db("testblob") or die(mysql_error()); // get the image from the db $sql = "SELECT image FROM testblob WHERE image_id=0"; // the result of the query $result = mysql_query("$sql") or die("Invalid query: " . mysql_error()); // set the header for the image header("Content-type: image/jpeg"); echo mysql_result($result, 0); // close the db link mysql_close($link); } else { echo 'Please use a real id number'; }
