Problem with 2 database queries and fetching data from row - php

Question

Having a problem with the 2nd query. when it gets to mysql_fetch_row - it kicks back
mysqli_fetch_row() expects parameter 1 to be resource, boolean given
Now I have also tried fetch assoc. But that as well kicks back an error. I have tried doing the 2nd query with '$id' and without it, yet still nothing. I think i am missing something very obvious.
I have went through many of the common post on here that refer to the error I am given but still haven't found a solution.
$con1 = mysqli_connect($dbhost,$dbuser,$dbpass,$dbname);
$con2 = mysqli_connect($dbhost,$dbuser2,$dbpass2,$dbname2);
// Check connections
if($con1)
{ echo("1st Connection Successful "); }
else
{ echo("1st Connection Failed "); }
if($con2)
{ echo("2nd Connection Successful "); }
else
{ echo("2nd Connection Failed "); }
//start first database query
$query = "SELECT id, email FROM ow_base_user ORDER by ID LIMIT 30";
$result = $con1->query($query);
while($row = $result->fetch_row()) {
$rows[]=$row;
$id = $row[0];
$email_row = $row[1];
$email_sub = substr($email_row, 0, 2);
if ( $email_sub == "dk" ) {
$email = "1"; }
elseif ( $email_sub == "sv" ) {
$email = "3"; }
elseif ( $email_sub == "no" ) {
$email = "4"; }
elseif ( $email_sub == "nl" ) {
$email = "5"; }
elseif ( $email_sub == "de" ) {
$email = "2"; }
elseif ( $email_sub == "fi" ) {
$email = "6"; }
else {}
if (isset($email)) {
//start 2nd database query
$query2 = "SELECT country_id FROM website_user WHERE userId = $id LIMIT 1";
$result2 = $con2->query($query2);
$row2 = mysqli_fetch_row($result2);
$country = $row2[6];
if (isset($country)) {
}
if (DEVMODE) {
echo "user id = ".$id." -- ";
echo "email = ".$email." -- ";
echo "COUNTRY = ".$country."<br />";
}
}
}
So changed the code around a bit to print out errors incase the query wasn't going through.
If($result2 === false) {
echo "error while executing mysql: " . mysqli_error($con2);
} else {
after adding this in I received the error.
mysqli_error() expects parameter 1 to be mysqli, null given
Ok so, these errors where caused by a typo in the databse table name thanks for pointing out the error report all method in the comments.
UPDATE: so after fixing the connection issue. I receive Notice: Undefined offset: 5 in $country = $row2[6];
UPDATE: after change $country = $row2[0]; - This solved the final issue.

for development build you can use
error_reporting(E_ALL);
ini_set('display_errors', 1);
which showed the database table was misspelled. after that, had to change the which row was being pulled since it was only 1 row, instead of all rows.
