I have this code below that selects all id's for posts and then the snippet below that sees if there is a match. If a match it says duplicate. I tested it by using print command to print $test and print $unique but it only shows one id rather than all ids. How can i fix this code so it will display all id # and then compare to see if a duplicate exists and if exists it will say "duplicate."
$sql="SELECT `Post_id` from `posts`";
$result=mysql_query($sql);
$query = mysql_query($sql) or die ("Error: ".mysql_error());
if ($result == "")
{
echo "";
}
echo "";
$rows = mysql_num_rows($result);
if($rows == 0)
{
print("");
}
elseif($rows > 0)
{
while($row = mysql_fetch_array($query))
{
$storedid = htmlspecialchars($row['Note_id']);
print("");
}
}
//This $test id exists and $storedid should contain
3VRDY but it still goes through
$test = "3VRDY";
if ( $storedid == $test ) {
echo("duplicate");
die();
} else {
echo("");
}
