Bug description: mysql_num_rows() not valid
I have a very simple PHP script, that searches a small mysql database for a
result. And the result that I keep receiving pertaining to the
mysql_num_rows() function is listed below.
Warning: mysql_num_rows(): supplied argument is not a valid MySQL result
resource in /bookorama/results.php on line 29
Number of books found:
Here is some of the PHP script.
<?
trim($searchterm);
if(!$searchtype || !$searchterm) {
echo "You have not entered search details. Please go back and try
again.";
exit;
}
$searchtype = addslashes($searchtype);
$searchtype = addslashes($searchterm);
@ $db = mysql_connect("localhost", "headdive_jazz", "jazz");
if(!$db) {
echo "Error: Could not connect to database. Please try again later.";
exit;
}
mysql_select_db("books");
$query = "select * from books where ".$searchtype." like
'%".$searchterm."%'";
$result = mysql_query($query);
$num_result = mysql_num_rows($result);
echo "<p>Number of books found: ".$num_results."</p>";
for($i=0; $i < $num_results; $i++) {
$row = mysql_fetch_array($result);
echo "<p><strong>".($i + 1).". Title: ";
echo htmlspecialchars(stripslashes($row["title"]));
echo "</strong><br>Author: ";
echo htmlspecialchars(stripslashes($row["author"]));
echo "<br>ISBN: ";
echo htmlspecialchars(stripslashes($row["isbn"]));
echo "<br>Price: ";
echo htmlspecialchars(stripslashes($row["price"]));
echo "</p>";
}
?>
