module Admin Services tab issue

[xauen]

I have a custom Admin Services Tab function in our module. It is not getting errors on page but it is not showing on the Admin Product/Services tab (image link http://prntscr.com/fto3h).

My WHMCS install is version 5.03

Please see below the module code:

 

 

 

function thismodule_AdminServicesTabFields($params) {

$link = mysql_connect($params["configoption1"], $params["configoption3"], $params["configoption4"]);
if (!$link) {
return 'Could not connect to MySQL';
}

# Select DB
$db_select = mysql_select_db($params["configoption2"], $link);
if (!$db_select) {
return 'Could not select database';
}


# Select row from database
$sql1 = mysql_query("SELECT `port` FROM `userdata` WHERE `username` = '".$params["username"]."'", $link);
$sql2 = mysql_query("SELECT `port2` FROM `userdata` WHERE `username` = '".$params["username"]."'", $link);
$sql3 = mysql_query("SELECT `port3` FROM `userdata` WHERE `username` = '".$params["username"]."'", $link);

if (!$sql1) {
return 'Could not select row from database '.mysql_error($link);
} else {
return 'success';
}

$fieldsarray = array(
'Field 1' => '<input type="text" name="modulefields[0]" size="30" value="'.$sql1.'" />',
'Field 2' => '<input type="text" name="modulefields[1]" size="30" value="'.$sql2.'" />',
'Field 3' => '<input type="text" name="modulefields[2]" size="30" value="'.$sql3.'" />',
);

return $fieldsarray;

}

 

 

Hope you can help me with this
