HTML Form Submit Button Does Not Write In $_POST

I want a form with 4 submit buttons. Once any of them is pressed, they shell call the same page with different content. To determine which content it is, I will write a PHP Script,

Solution 1:

Maybe you want to write name = "nv_select". You forget equal. Of course name atributes should be different nv_select1, nv_select2 etc.

Solution 2:

with input type="button" instead of "submit" you should be able to achieve the desired result.
