I can not use -
com_ajax
Any other components
My goal is to send POST data when checkbox is 'checked' using jquery AJAX
I've mod_test module.
default.php
<form method="post" action="this.form.submit();" name="form1">
<input type="checkbox" name="checkboxList[]" onclick="function1();" value="1">value1</input>
<input type="checkbox" name="checkboxList[]" onclick="function1();" value="2">value2</input>
<input type="checkbox" name="checkboxList[]" onclick="function1();" value="3">value3</input>
</form>
<script>
function function1() {
var data = $("[name='form1']").serialize();
$.ajax({
url: "modules/mod_test/mod_test.php",
type: "POST",
async: true,
cache: false,
data: data,
success: function(data){
alert(data);
}
});
}
</script>
1. Is my jquery (for ajax call) correct?
2. How can I pass POSTED data to my modules mod_test.php? Is the url correct? Is there an alternative?
- I understand, that every joomla file has [i]defined('_JEXEC') or die;[/i], but even if I comment it out - I dont get ajax post data if I do print_r($_POST); Why? I also understand its security issue. But this makes me wonder.
3. Is there a way of writing some kind of function or something, to use only module and send POSTED data to mod_test helper.php/mod_test.php using AJAX? (without writing component)
I'm open to ideas. Please, don't ask why I dont use components. I'm open for some creative brain-storming.

Why not use the standard com_ajax component? This is what it is designed for -- to let you make ajax calls from a module. See https://docs.joomla.org/Using_Joomla_Ajax_Interface.

As I mentioned, com_ajax is a component therefore - not an option for me. I'm looking for some alternative. Isn't there a possibility avoid components (even if it's pain in ass to achieve it)?

I'm not sure what you mean by "avoid components". The com_ajax is sitting there in every Joomla installation. You don't need to do anything to use it. It is just a vehicle for allowing you to call methods in your module's helper without needing to re-invent the wheel. Joomla is set up so that a URL is directed to a component, not to a module. It seems like you are trying to "swim upstream" instead of taking advantage of how Joomla is designed to solve this issue.

That might be true, but I am really looking for the alternative right here. I'm pretty sure this has be done somehow in the past. Com_ajax was introduced only in 3.2+ versions. What did ppl do before? That's what I want to find out. It's more like a research

Before com_ajax, people either created a proper component for this or
they hacked it by putting a seperate PHP file into their modules folder,
introducing lots of security issues in the process.
Are you trying to develop a module or are you just doing research? If
you are developing, use com_ajax. That is the way it is supposed to be
done and to be blunt: Asking for a different solution for a fourth time
will not get you any better answers.

Can you please give me an example on "hacked by putting seperate php file into their modules folder"?

It is a simple standalone PHP script in the modules folder that you
would call directly via JS. But since that is not inside the Joomla
framework, you don't have any of the luxuries that the framework
provides and none of the security benefits. The "hacked" was refering
more to the fact that people found a nasty workaround. The security
issues are mainly in that PHP file, which often enough does not do all
necessary checks to prevent SQL injections and similar stuff.
