[SOLVED] When empty set results from SELECT query?

Recommended Posts

$query = "SELECT * FROM soft WHERE name = '$search'";
if ($result = $mysqli->query($query)) {
while ($row = $result->fetch_row()) {
	printf ("ID: %s<br> Name: %s<br> Path: %s<br> Comment: %s<br>\n", $row[0], $row[1], $row[2], $row[3]);
}
printf ("End of results.<br>\n");
$result->close();
}

 

My problem is that if there is no entry matching the search, the select query still returns a true value even if it's an empty set. How can I tell if the query returns an empty set (no matches) vs the normal array?

You need to count your records instead of simply checking to see whether or not your query is TRUE:

<?php
$query = "SELECT * FROM soft WHERE name = '$search'";
if ($result = mysql_query($query)) 
  {
  if (mysql_num_rows($result) > 0)
  {
    // Do your loop since you have records returned
  }
}
?>
