Your checkboxes will not send any data because they do not have the value attribute.
Change your html to:
<input type="checkbox" name="test[]" value="1" >
<input type="checkbox" name="test[]" value="2" >
<input type="checkbox" name="test[]" value="3" >
<input type="checkbox" name="test[]" value="4" >
<input type="checkbox" name="test[]" value="5" >
<input type="checkbox" name="test[]" value="6" >
<input type="button" id='send'>
Note that I also changed the names to test[], this will send an array of all the checkboxes that are checked.
For example: I check checkbox 1 and checkbox 3, the value that the server will receive is in $_REQUEST['test'] (either POST or GET), and will be an array with content [1,3].
If none of the checkboxes is marked, the $_REQUEST['test'] will be not set which you can check server side using isset().
