CSN-Ajax programming template

The idea is very simple, but it provides significant advantages compared to the code without using this template, it has the potential to be actively used. Strange, but I have not seen anything like this in any trend code for reuse, so I called the template "CSN-Ajax" based on the site name and the project "SKY Framewok", in which the template first appeared - CoreSky.Net , in my project. I will describe an implementation example here based on the use of PHP, jQuery and MVC patterns. So, briefly, without comments:



1. Make a wrapper function in javascript named ajax (action, postfields, func, controller) for $ .post (..). A typical call in the application code:

ajax('edit', post_vars, function(data) {
  // ....
})

2. «» jQuery $.post(..), -. controller , , «document.location.href», , (query string, GET ). .. controller , « » , .



3. , . ajax(..) GET «controller» - "__AJAX__=_"



4. index.php, :

<?php
if ('__AJAX__' == key($_GET)) {
  define('AJAX', true);
  array_shift($_GET);
} else {
  define('AJAX', false);
}

.. javascript ajax(..), «», ajax , , . , : , layout style , . , , layout style.



5. , error handler php PHP set_error_handler(..), Exception. AJAX, , , JSON , «catch_error», :

echo json_encode(['catch_error' => "$this->errors<h1>Stdout</h1>" . html($stdout)]);

, , STDOUT PHP ob_start(). ajax(..), , JSON «catch_error», , , . , .
