Call PHP function with parameter onSubmit / onClick event

I have a PHP file containing a shop class, which has several static public functions like:

File : shop.php

And one of my function is :

static public function insertProductIntoBasket($id, $quantity, $name)

{ 
$basket = self::createBasket(); // We create the basket in another function if not exist before handling a product for a basket.

$query = mysql_query("INSERT INTO myTable(id_order, id_product, quantity_product, file_name)
VALUES('".$basket['id_order']."', '".$id."', '".$quantity."', '".$name."')

;") or die($query.' '.mysql_error());

}

In another file (product file) I want to make a button, to handle this function, thank to an event on it.

So I am trying to call this PHP function insertProductIntoBasket($id, $quantity, $name) like this, with an event on a button:

File: product.php

<form name="addProduct" method="post" action="shop.php">
   <input type="submit" value="Add to basket" name="pdt_basket"/>
</form>

I saw that Javascript is handled when the button is pressed, and there is a way to call a function with AJAX. But I definetly do not know how to pass parameters from my insertProductIntoBasket function.

Use ajax to call product.php

function blah() { $.ajax({ url: 'product.php?arg1=val1&arg2=val2&arg3=val3' }); }

and use $1 $2 etc to access passed values

//Before you use ajax, you have to know how to pass(POST) parameter first,
//The following is a simple example

/*In product.php
* if you want to send parameter from this page,
* just create more input field within the form
* then the form will "POST" those parameter to shop.php
*/

<form name="addProduct" method="post" action="shop.php">
   <input name="id_order" type="text" value="1" />
   <input name="id_product" type="text" value="1" />
   <input type="submit" value="Add to basket" name="pdt_basket"/>
</form>

/*In : shop.php
*you can get those parameter by using $_POST['input_name']
*the following is the example to get the id_order and id_product send from product.php
*/

$id_order = $_POST['id_order'];
$id_product = $_POST['id_product'];

/* Then you can try to call function inside shop.php will calling function directly */
insertProductIntoBasket($para);

//You may not need AJAX in this case, I will update my answer if you require for it.

Just call the function from with your shop.php file. You can get the post variables and call the appropriate functions from there.
