从数据库中删除行不起作用

Question

I'm trying to make a function that would delete from a mysql database a record from a specific table specified by the user and the row which will be used in the WHERE clause depends on the table chose.

This is what I have:

 $table=$_POST['table'];
 $title=$_POST['title'];
 if($table=="clients")
     $row="fullname";
 else if($table=="books")
     $row="title";
 else if($table="actors")
     $row="fullname";
 else if($table="employees")
     $row="fullname";

 $result = mysqli_query($con,"DELETE from $table WHERE $row='{$title}'") or die (mysqli_error($con));

 if($result) {
     $_SESSION['updateinfo']='deleted';
     header("location:index.php");
 } else {
    $_SESSION['updateinfo']='not deleted!';
    header("location:index.php");
 } 

Well, it works fine when I try to delete from clients,books,actors, but it does not work for employees.

I get the message " deleted ", but its still there.No error, no nothing. Also I would have to add 10 more those tables, is there a better way to do this?

I tried to echo $table, $title and $row and it seems that the SELECT from the HTML form only passes to the PHP script the correct value for the first 3 options, for the rest of them it passes a wrong value, below is my html form

 <select name="table" style="padding:5px;margin:5px;width:200px;">
  <option value="clients" selected="selected">Clients</option>
  <option value="books">Books</option>
  <option value="actors">Actors</option>
  <option value="employees">Em</option>
  <option value="other1">smthother</option>
  <option value="other2">smtoher2</option>
</select>
