Creating a form in tpl file

[kuporc]

Hello , 

 

I'm currently working on a small module where i create a form in .tpl and then submit the form into main module php file function.I'm stuck in the part how to link from .tpl form back to module main php file.

 

Here is the code:

 

TPL file

<form action="?????" method="POST" class="form" id="discountForm">
	  <div class="form-group">
	    <label for="email">Email address:</label>
	    <input type="email" class="form-control" id="email">
	  </div>
	  <div class="checkbox">
	    <label><input type="checkbox" name ="discountCheckbox" id="discountCheckbox">{$checkbox_text}</label>
	  </div>
	  <br />
	  <button type="submit" class="{$submit_button_class}">Submit</button>
</form>

I would like to know how to get the action link so i can link back to my module main php file , and how to get the input value ?
