multiple buttons on a form

Question

I have a clear button that I want to tie into some php coding. how do I detect if the clear button is pressed. When the user press clear, i\'m going to have it update a sql

Answer 1

You check the post or get data from your form, using the name of the button:

  Clear
  Submit

PHP (after submission):

if(isset($_POST['reset'])) { /* ...clear and reset stuff... */ }
else if(isset($_POST['submit']) { /* ...submit stuff... */ }

Alternatively, you have two buttons with the same name, which both submit your form, and if/else their values:

  Clear
  Submit
  Something Else

PHP (after submission):

if($_POST['submit']==0)      { /* ...clear and reset stuff... */ }
else if($_POST['submit']==1) { /* ...submit stuff... */ }
else if($_POST['submit']==2) { /* ...do something else... */ }
