I am trying to use the SQLSVR function to return a true or false from a query, i was using ODBC_connect and ODBC_results.
This was my original script:
function user_exists($username)
{
$result = odbc_exec (odbc_connect("book", "", ""), "select count ('user_id') FROM [User] WHERE username = '$username'");
return (odbc_result($result, 1) ? true : false);
}
But trying to use the SQLSVR function im not sure where to go. This is what i have so far.
function user_exists($conn, $username) {
$sql =("select count ('user_id') FROM [User] WHERE username = '$username'");
$stmt = sqlsrv_query( $conn, $sql);
$name = sqlsrv_get_field( $stmt, 0);
If ($name = 1) {
Return True;
}
else{
Return False;
}
}
You need to pass $conn
to user_exists()
otherwise it will not be visible in function body.
function user_exists($conn, $username) {
...
And also, you need to call user_exists(...)
somewhere to make it all work. Putting function method is not equivalent of calling it.
EDIT
This code is redundant:
$test = sqlsrv_has_rows($result);
return (($test == true) ? true : false);
as it is sufficient to just:
return sqlsrv_has_rows($result);
