需要一个调用php函数的按钮

Question

I need to have a button that calls a php function to resort displayed data from the db. How the heck do I do this? I just found out that because php is server side this sucks. So any help please?

This is a job for ajax, as others mentioned. If I may elaborate, if you're starting out, I HIGHLY recommend using a javascript library to make your life easier. With prototype, here's what your button might look like:

<input type="button" id="button_foo">Button</input>

Here's what your javascript might look like:

$('button_foo').observe('mousedown',function(e){
    new Ajax.Request('handler.php',{
        method:'post',
        onSuccess:function(t){
            $('table_bar').update(t.responseText);
            }
    });
});

This may seem a little daunting at first, but I think basic js has a pretty manageable learning curve when using a library. The above code would take whatever handler.php outputs, and replace the contents of an element with and id of "table_bar" with the returned html.

if you do decide to use prototype, the docs are really helpful and easy to understand, and there is a really excellent book by pragmatic press on the subject that'll have you understanding it very quickly.

Hope that helps!
