$result=mysqli_query($dbc, $query) or die('error query');

You have single quotes and not backticks in your query.

$query="INSERT INTO userdate('name','city','emailid','pledge','date') VALUES ('$name','$city','$emailid','$comment',NOW())";

Should be:

$query="INSERT INTO userdate(`name`,`city`,`emailid`,`pledge`,`date`) VALUES ('$name','$city','$emailid','$comment',NOW())";
