Can someone explain a little bit more (more then jQuery's docs) about
how the $.post operates? I know it's a "shortcut" for .ajax and it
uses the HTTP POST request. So I'm guessing it's not sending the same
request the form would send... i.e. you HAVE to provide the data to
the php script through $.post. Is that correct? Then my next
question is, if I have a set of check boxes and name each box
"services
[]"... PHP will load the value of each into an array. Is there a
quick way to assign these value to a JS variable to pass onto the PHP
script? Because PHP doesn't create that array until the POST request,
correct? But since I am using $.post, PHP is not making the request,
therefore doesn't create the array. Is that right? So I must do it
manually in JS... what would be best/quickest way to go about this?
Thanks for the help.
You can send the form's input values as a serialized string
using .serialize(). So, if you have a form with id="foo" you could do
something like this:
$('#foo').submit() {
var formData = $(this).serialize();
$.post('/path/to/file/', formData, function() {
// do something when post is successful.
});
return false;
});
