Is there any way to change all method="post" to method="get" through code?

Question

PHP

A stupid problem arose, I wrote a code to send a form to php, the variable that sends the data is GET.
Does the form have a POST method in the page code? , but the problem is that I can't find that page in the catalog (
site on joomla, here is a link to this page

Answer 1

Through ftp go through all the files and find those inside which will be the desired line. I know for sure that notepad++ has such a feature. But I think you get the point!

Answer 2

 Shovel. On all pages, or on pages with a form, insert this js

$(document).ready(function(){
   $('form').attr('method','post');
});
