Do you supply a link_id to your mysql_query?

Like mysql_query($sql, $linkId);

The error indicates that the second argument is incorrect. Did your mysql_connect and mysql_select_db go without errors?

Here is a snap of what I have:


if (mysql_errno()) {
      printf("Connect failed: %s\n", mysql_errno());
      exit();
} else {
      $sql = "SELECT id, businessname, primarycontact, primaryphoneareacode, primaryphoneprefix, primaryphonenumber, primarycontactemail FROM vendor WHERE stamp < DATE_ADD(NOW(),INTERVAL -10 DAYS) ORDER BY stamp ASC";
      $res = mysql_query($sql, $mysql);
	  
 if (($res)>1) {
						while ($newArray = mysql_fetch_array($res, MYSQL_ASSOC)) {
                                                $link2="<a href=\"vendor_details.php?id={$newArray['id']}\">$detailsimage</a>";
						$businessname = $newArray['businessname'];
						$primarycontact = $newArray['primarycontact'];
						$primarycontactemail = $newArray['primarycontactemail'];
						$primaryphoneareacode = $newArray['primaryphoneareacode'];
						$primaryphoneprefix = $newArray['primaryphoneprefix'];
						$primaryphonenumber = $newArray['primaryphonenumber'];
						$stamp = $newArray['stamp'];

The error indicates that your $mysql variable is not a valid mysql link. I find it strange though that your code doesn't act on the mysql_errno() clause.

Can you try (for debugging purposes) an on die(mysql_error()) after your mysql_connect and your mysql_select_db() ?

$mysql = mysql_connect($host, $user, $pass) or die(mysql_error()));
mysql_select_db($db, $mysql) or die(mysql_error());

Alternatively you could use
if (mysql_errno()) {
      printf("Connect failed: %s\n", mysql_errno());
      exit();
} else if(!is_link($mysql)) {
      printf("Connect failed for an unknown reason");
      exit();
} else {

I ran the query locally and didn't find any error in it. I don't know what else to tell you when no errors occur.
