Populating select option using php

Question

I have a select option that load categories from MySQL using php, i need when the user choose a value from the category Select, another select option appears and populates the products of this category. The two select should be in the same form because i need to pass the selected category and the selected product when submitting this form.

You have to use AJAX on the web page so to 'talk to' the php code and to populate the second option list — user2417483

<select name='test1' id='test1'>
    <option value='1'>1</option>
    <option value='2'>3</option>
    <option value='3'>3</option>
    <option value='4'>4</option>
</select>

Html

<select name='tes2' id='test2'>
</select>

Ajax

$("#test1").on('change',function(){
$.ajax({
 url : 'someurl',
 data: { data },
 dataType: 'json',
 async: false,
 success: function(res){
 //Populate second select
 }
});
});
