Laravel Ajax Call To Controller

I am pretty new with Laravel and I am having an issue with accessing a specific method in my Controller. I am trying to change a Database value (language) based on a dropdown menu.

Solution 1:

This is a complete answer to your question

Use a POST request instead of GET

Because you are updating the user's language it's more secure to use a POST request

// MAKE AJAX CALL
$.ajax( {
    // url:'/settings/profile',url:'./test',
    method:'POST',
    data: {
       strLang: newLang
    },
    success: function( bolUpdated ) { 
        if( bolUpdated ) { 
            alert('OK');
        }   
    },  
    fail: function() {
        alert('NO');
    }   
}); 

and don't forget to pass the strLang in your post request via the data attribute.

Protect against CSRF attacks

Store the csrf token in a HTML meta tag:

<metaname="csrf-token"content="{{ csrf_token() }}">

Automatically add the token to all request headers:

$.ajaxSetup({
    headers: {
        'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
    }
});

Create a route to handle your ajax request:

Route::post('test', 'ProfileController@update');

Get strLang via the $request object in your controller:

functionupdate($request) { 

    $objUser = Auth::User();

    // UPDATE LANGUAGE$bolUpdated = $objUser->updateLanguage( $request->strLang );

    // RETURNreturn response()->json( $bolUpdated );
}

If you are using HTML5, your settings.profile.blade should look like this:

<select id="accountLanguage" class="form-control" method="GET">
    <option value="en" {{ ($strLanguage == 'en') ? 'selected' : '' }} >English</option>
    <option value="es" {{ ($strLanguage == 'es') ? 'selected' : '' }} >Español</option>
    <option value="he" {{ ($strLanguage == 'fr') ? 'selected' : '' }} >French</option>
</select>

In your index method, $objUser already contains the lang property

publicfunctionindex() {

    $objUser = Auth::User();

    return view("application.settings.profile",[
        'objUser' => $objUser
    ]); 

}  

Getting the new lang from select element:

$('#accountLanguage').change(function () {
     initProfileManager(this.value);
});

Solution 2:

Change your route to:

Route::post('test', 'ProfileController@update');

and your ajax object:

method:'POST',

You have to actually pass $strLang somehow, too (since the update() method expects this, as the error message states).

Oh, and you really don't need the method attribute in your select HTML ;)

Solution 3:

You should define language in the route

Route::get('test/{strLang}', 'ProfileController@update');` 

as well as pass it as a variable to the url in js code: '/test/' + strLang
