在HTML onClick（）事件上调用PHP函数？

Question

I know there is one answer out on stackoverflow, but that is related to form submission.

Mine is different implementation. I need to call a function, which registers a variable in $_SESSION[], and then redirects to another page(html/php). Now I don't want to use AJAX. Please help me with this.

Answer 1

That is not possible. Php is executed on the server before the html is served. All php functions have been evaluated to HTML at the time onClick occurs.

You can do a form and set action="someFile.php" and use $_GET['someVaiable'] or $_POST['someVariable']

Answer 2

Use a form with a submit button.

Store whatever you need to pass in hidden inputs (or use non-hidden inputs if it is supposed to be user configurable).

When the form is submitted, sanity check the data, set any session data you want, then redirect.

You don't need to use a JavaScript click event. The default behaviour of a submit button will handle everything you've asked for (that the client could contribute).

Answer 3

If you are passing this with javascript to the php you could try

parameters.something = x;
parameters.somethingelse = y;
parameters.somethingelse1 = z;
$.post("class_handler", parameters)

and then your PHP needs to have a class_handler that will react when POST occurs.
