not a valid MySQL-Link resource?

[theepicgeno]

<?php
$con=mysqli_connect("blah","blah","blah","blah");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}


if ($_POST['rateup'])
{
mysql_query($con, 'UPDATE pictures SET likes = likes + 1 WHERE likes = 0');
}


$results = mysqli_query($con,"SELECT * FROM pictures ORDER by id DESC") or die(mysqli_error($con));


while($row = mysqli_fetch_array($results))
{
echo "<center><font face='courier new'><u><b>" . $row['title'] . "</b></u><br /></center>";
echo "<center>" . $row['content'] . "<br /></center></font>";


echo "<center><form action= " . $_SERVER['PHP_SELF'] . " method='post' name='rateform'></center>";
echo "<center><input name='rateup' type='image' src='http://www.thevideotube.tk/imgs/thumbup.jpg' id='rateup' value='rateup' /></center>";
echo "<center></form></center>";


echo "<hr style=width:600px />";
}
mysqli_close($con);
?>

Hey! I have a problem... The above code shows every post in the database. Everything works fine except when i click the rateup image, it gives me this error:

Warning: mysql_query(): supplied argument is not a valid MySQL-Link resource in/home/a9004837/public_html/ap/autoPage-new.php on line 11

If anyone can help me, that would be great!

If you're still unsure what I'm getting at, try writing out a list of the functions you're using in this file. Carefully. Edited August 27, 2013 by requinix

Just have to pay attention to little things. The error told you where the error was so your first step should be to look at the line very carefully and see if there aren't any little mistakes like that.
