get value from MySQL database with PHP

Question

$from = $_POST[\'from\'];
$to = $_POST[\'to\'];
$message = $_POST[\'message\'];

$query  = \"SELECT * FROM Users WHERE `user_name` = \'$from\' LIMIT 1\";
$result = m         


        

Answer 1

though it should. try this code

$from    = mysql_real_escape_string($_POST['from']);
$to      = mysql_real_escape_string($_POST['to']);
$message = mysql_real_escape_string($_POST['message']);

$query  = "SELECT * FROM Users WHERE `user_name` = '$from' LIMIT 1";
$result = mysql_query($query) or trigger_error(mysql_error().$query);
$row = mysql_fetch_array($result, MYSQL_ASSOC);
$fromID = $row['user_id'];
echo $fromID;

if it will throw no errors but still print no id, add this line

var_dump($row);

and post here it's output

not that you shouldn't use a user name but user id to address particular user.
