Get number of rows from a select count MySQL statement
$How_Many_Manufacturers = "SELECT COUNT(manufacturer), manufacturer
FROM products
WHERE name LIKE '%$new_title%'
GROUP BY manufacturer";
$result2 = mysql_query($How_Many_Manufacturers, $connection) or die(mysql_error());
$num_rows = mysql_num_rows($result2);
if ($num_rows == 0)
{
echo "<div id=\"noMatches\">No Matches</div>";
}
else {
}
T开发者_C百科he if statement will not work. How can I correct this script?
@Arjan You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '-25,25' at line 4 -RPM
make sure you escape $new_title in the query.
$How_Many_Manufacturers = "SELECT COUNT(manufacturer), manufacturer
FROM products
WHERE name LIKE '%".mysql_real_escape_string($new_title)."%'
GROUP BY manufacturer";
SELECT COUNT will always return a row (even if the count is zero). Simply remove the COUNT, or fetch the row to see the count.
