Check for validation from different tables - joomla - php

Question

I am new to joomla. I am using RSDirectory Component. In this i have to customize validation. i have a file named rsdirectory.php which is located at: administrator>components>com_resdirectory>helpers>rsdirectory.php.
I have a table, table1. In which a unique code is stored. Now i want to fill a form using that code if exist then query will execute otherwise my validation code will be execute. i have done this successfully. Now i have an another table, table2 in which my data is storing when i am filling a form with unique code. i just want to check my unique code whether it is exist in table2 or not. if exist validation will execute.i want to use same function for both.
Here is my code. Thanks in advance.
public static function uniquestacksfield($value, $column,$column1,$id1=null, $id = null){
// Get DBO.
$column = 'uni_code';
$db = JFactory::getDBO();
$query = $db->getQuery(true)
->select($db->qn('id'))
->from($db->qn('#_table1', 'e'))
->where($db->qn($column) . ' = ' . $db->q($value));
$db->setQuery($query);
$entry = $db->loadObject();
if ($id) {
$query->where($db->qn('e.id') . ' = ' . $db->q($id));
}
$db->setQuery($query, 0, 1);
return $db->loadResult();
/------------------another query-----------------------/
$column1 = 'uni_code2';
$db1 = JFactory::getDBO();
$query1 = $db1->getQuery(true)
->select($db1->qn('entry_id'))
->from($db1->qn('#_table2', 'c'))
->where($db1->qn($column1) . ' = ' . $db1->q($value));
$db1->setQuery($query1);
$entry1 = $db1->loadObject();
if ($id1) {
$query1->where($db1->qn('c_entry_id') . ' = ' . $db1->q($id1));
}
$db1->setQuery($query1, 0, 1);
return $db1->loadResult();
}`

$column1 = 'uni_code2';
if($column == 'uni_code') {
$query = $db->getQuery(true)
->select($db->qn('id'))
->from($db->qn('#_table1', 'e'))
->where($db->qn($column) . ' = ' . $db->q($value));
$db->setQuery($query);
$entry = $db->loadObject();
if ($id) {
$query->where($db->qn('e.id') . ' = ' . $db->q($id));
}
} else {
$query = $db->getQuery(true)
->select($db->qn('entry_id'))
->from($db->qn('#_table2', 'c'))
->where($db->qn($column1) . ' = ' . $db->q($value));
$db->setQuery($query);
$entry = $db1->loadObject();
if ($id) {
$query->where($db->qn('c_entry_id') . ' = ' . $db->q($id1));
}

$db->setQuery($query, 0, 1);
$item = $db->loadResult();
