Ajax post to route in Laravel 4
提问by Pars
I am going to send some data to current pageusing ajax to insert something in database.
Assume this ajax code:
我将使用 ajax将一些数据发送到当前页面以在数据库中插入一些内容。
假设这个ajax代码：
$('#newPost :submit').click(function(e){
var BASE = 'http://localhost/project/public/';
e.preventDefault();
$.post(BASE, {
'message' : $('#newPost textarea.message').val()
}, function(data) {
$('#content').prepend('<p>' + data + '</p>');
});
});
This piece of code sends data to URL / and it works well. but I want to send it to a Route.Namewhich route sends it to a controller@action.
is there anyway or workaround to do this?
这段代码将数据发送到 URL / 并且运行良好。但我想将它发送到一个Route.Name路由将它发送到一个控制器@动作。
有没有办法或解决方法来做到这一点？

In your route,
在你的路线上，
Route::get('data', array('uses' => 'HomeController@store'));
In HomeController,
在 HomeController 中，
public function store() {
$input = Input::all(); // form data
// validation rules
$rules = array(
'email' => 'required|email',
'name' => 'required',
);
$validator = Validator::make($input, $rules); // validate
// error handling
if($validator->fails()) {
if(Request::ajax()) { // it's an ajax request
$response = array(
'response' => 'error',
'errors' => $validator->errors()->toArray()
);
} else { // it's an http request
return Redirect::intended('data')
->withInput()
->withErrors($validator);
}
} else { // validated
// save data
}
}
And finally the script,
最后是剧本，
var root_url = "<?php echo Request::root(); ?>/"; // put this in php file
$('#newPost :submit').click(function(e){
var BASE = root_url + 'data';
e.preventDefault();
$.post(BASE, {
'message' : $('#newPost textarea.message').val()
}, function(data) {
$('#content').prepend('<p>' + data + '</p>');
});
});

You could change
你可以改变
var BASE = 'http://localhost/project/public/';
to
到
var BASE = '<php echo URL::route("name");?>'
Your route should then be:
你的路线应该是：
Route::post('action', array('as' => 'name', 'uses' => 'HomeController@action'));
Note the use of the named routesinstead of building the url using URL::to('controller/action')
请注意使用命名路由，而不是使用URL::to('controller/action')
