Question

I am having an issue trying to get the number of rows from a prepared statement query in php, my query looks as follows:

$DBH = getDBH();
$stmt = $DBH->prepare("SELECT info FROM list WHERE tag = ?");
$stmt->bind_param("s",$tag);
$stmt->execute();
$stmt->bind_result($information);

and i basically just want to say if there is no result returned display “no result returned” can anyone please help?

You need to use $statement->store_result() first. Using your code:

$DBH = getDBH();
$stmt = $DBH->prepare("SELECT info FROM list WHERE tag = ?");
$stmt->bind_param("s",$tag);
$stmt->execute();
$stmt->store_result();
$num_rows = $stmt->num_rows;
$stmt->bind_result($information);
