$_post[nameofinput] 

you cannot send buttons' values. use radio fields, example:

<input type="radio" name="choice" value="1" /> <input type="radio" name="choice" value="2" /> 

or can use dropdown too:

<select name="choice">     <option value="1">option 1</option>     <option value="2">option 2</option> </select> 

then in php:

echo $_post['choice']; // possible results: null/1/2
