I am learning mysql but I am not sure what is next going to be here in this code to get the matching row as result, how can I fetch that?
$stmt= $db->prepare("SELECT * FROM users WHERE email=? and password = ?");
$stmt->bind_param("ss", $_POST['user_name'],md5($_POST['user_pass']));
$stmt->execute();
I am sure this is a simple one for you, please help me out in learning things.
Take a look at example #6 on this page
Here's the relevant bit, right after the bind_param() and the execute():
$out_id = NULL;
$out_label = NULL;
if (!$stmt->bind_result($out_id, $out_label)) {
echo "Binding output parameters failed: (" . $stmt->errno . ") " . $stmt->error;
}
while ($stmt->fetch()) {
printf("id = %s (%s), label = %s (%s)\n", $out_id, gettype($out_id), $out_label, gettype($out_label));
}
Since I don't know what columns you are pulling in with your SELECT *
I'll just leave the example as it stands.
You can also use fetch_assoc()
which is probably a little easier to use and ends up being used a lot more commonly. Digging from the same page on php.net we get this relevant portion from example #8 (actually I had to modify it somewhat - example #8 is doing some funky stuff with buffering):
if (!($res = $stmt->get_result())) {
echo "Getting result set failed: (" . $stmt->errno . ") " . $stmt->error;
}
while ($row = $res->fetch_assoc()) {
var_dump($row);
}
$res->close();
