Very helpful, but on my own programming I created some unknown error. Hope some one can help.

here is my error I'm getting :(


You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '= '1'' at line 1



<meta name="generator" content="Namo WebEditor(Trial)">
<?PHP
// Get db connections
include ("config.php");
// Make a MySQL Connection

$link2 = mysql_connect( $dbhost, $dbuser, $dbpass)or die("Could not connect: ".mysql_error());


mysql_select_db($dbname) or die(mysql_error());



$query = "INSERT INTO Image (ImagePath)
VALUES('$ImagePath')";
mysql_query($query) or die(mysql_error());

$ImagePath = ""; // Clear variable so I know the image if from the db

$result = mysql_query("SELECT ImagePath FROM Image where $id = '1'") or die(mysql_error());

// Make sure you actually get a result:
if (mysql_num_rows($result) != 1){
$error = "Bad Login";


echo '<font color="black"><a href="imagedb.php" target="_self">ImagePath</font></a> not found, re-enter';


} else {

echo "<img src=\"$ImagePath\" />";

$ImagePath = "";// Clear variable so I know the old variable will not be reinserted in the db again.

echo '<font color="black">Click here to insert a new <a href="imagedb.php" target="_self">ImagePath</font></a> in the db.';

}


mysql_close();


?>

Here is a much simpler way. Just upload images (accepted types can be defined within the curly braces) to the specified folder and it will pick one automatically, regardless of name or the number of images:

$folder = 'images/random';
$images = glob( $folder . '/*.{jpg,gif,png}', GLOB_BRACE );
$image = $images[ array_rand( $images ) ];
echo '<img src=" . $folder . '/' . $image . " alt="' . $image . '" />';

Here is another method :)

$banners = array('/img/banner.jpg', '/img/banner2.jpg', '/img/banner3.jpg');
shuffle($banners);
echo ' <img src="'.$banners[0].'" width="123" height="123" alt="banner" /> ';

oops... missing a few single quotes in there, as well as having included a bit of flawed logic, for all you copy 'n' pasters ;)

$folder = 'images/random';
$images = glob( $folder . '/*.{jpg,gif,png}', GLOB_BRACE );
$image = basename( $images[ array_rand( $images ) ] );
echo '<img src="' . $folder . '/' . $image . '" alt="' . $image . '" />';

Thanks kbluhm - unfortunately I don't see any 'Thank you' button, so you'll just get this :)

Here is another method :)

$banners = array('/img/banner.jpg', '/img/banner2.jpg', '/img/banner3.jpg');
shuffle($banners);
echo ' <img src="'.$banners[0].'" width="123" height="123" alt="banner" /> ';

thanks for this method! it help me alot :)
