Hi, there are a few things wrong with your code, it seems like you dont understand the difference between a name and an id. An id is unique, a name is not. You can not retrieve a name with getElementById(). The following code will work in all browsers:
<?php
mysql_connect("localhost", "crispwer_vishal", "vishal@123") or die(mysql_error());
mysql_select_db("crispwer_navy") or die(mysql_error());
$query = "SELECT * FROM depatment";
$result = mysql_query($query);
?>

Please note that the names of the selects/checkboxes have changed, so use the following names to retrieve the values:
- $_POST['loginType'] // Admin, storekeeper or user
- $_POST['userDept'] // User department
- $_POST['login'] // Username
- $_POST['password'] // Password
