Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /home/user/public_html/im2db/image.php on line 14
This is the error I am getting
Here is the code:
Image.php
Am I supposed to add a exit(); after
$result = mysql_query ($sql, $conn);
line?
[PHP]<?php
// database connection
$conn = mysql_connect("localhost", "user", "pass") OR DIE (mysql_error());
@mysql_select_db ("user_images", $conn) OR DIE (mysql_error());
$sql = "SELECT * FROM images WHERE image_id=".$_GET["iid"];
$result = mysql_query ($sql, $conn);
if (mysql_num_rows ($result)>0) {
$row = @mysql_fetch_array ($result) or die (mysql_error());
$image_type = $row["image_type"];
$image = $row["image"];
Header ("Content-type: $image_type");
print $image;
}
