PHP将select设置为变量

Question

How can i make piece of select statement as php variable? Example: I have 2 options in select statement - edit and delete... I have those 2 options in dropdown menu... I want to make an mySQL query to edit or delete records/users from database...I tried to use switch and cases but it only gave me default as selecting.

<select name="editSelector">
<option name='edit'>Edit</option>
<option name='delete'>Delete</option>
</select>
<?php  
if (select == edit)
{
edit query here
}
elseif (select == delete)
{
delete query here
}
?>

I know that this code doesn't have any variables etc. Because i have no idea how to make option as variable. It's connected to database already. Thanks for the answer in advance.

Answer 1

    <?php
    if($_REQUEST['editSelector'] == "edit"){
edit here;
}
else if ($_REQUEST['editSelector'] == "delete"){
delete here;
}
    ?>

Plus :

    <select name="editSelector">
<option value='edit'>Edit</option>
<option value='delete'>Delete</option>
</select>
