I have a guitar lessons site where there is an exercises table. The original developers placed some functions in ExercisePresenter to retrieve other bits of data associated with an exercise, such as its url.
Here is a function in ExercisePresenter that returns url for an exercise:
public function url()
{
return '/guitar-lesson-ex/' . $this->urlName() . '/' . $this->id;
}
So now I am creating an event on new exercise created so I can use pusher notifications. In the EventServiceProvider I have this:
public function boot(DispatcherContract $events)
{
parent::boot($events);
Exercise::created(function ($exercise) {
// need to update lesson difficulty
$lesid = $exercise->lesson_id;
$les = \App\Lesson::find($lesid);
$dif = $les->difficulty();
DB::table('lessons')
->where('id', $lesid)
->update(['difficulty' => $dif]);
// lets trigger NewExerciseEvent to send pusher notifications
$url = $exercise->url;
event(new NewExerciseEvent($message));
});
}
I thought in above code $url = $exercise->url; would work since I see $exercise->url used successfully in exercise views. But it is returning $url as null. Now, there is no url column in the exercise database, so I figure somehow when $exercise->url; is used in a view, laravel is figuring out that the ExercisePresenter is able to return the url.
I am debugging through PHPStorm, but when I get to $url = $exercise->url; and step in, I am just taken through various bits of laravel code that looks for a method, etc. I am not savvy enough with laravel to figure out what it is doing here differently than in the view (too bad we can't debug views...), but each time I try this $url is returned as null.
Any idea how to get this to work properly in my EventServiceProvider?
Thanks!
Figured it out:
$url = $exercise->present()->url;
I had been searching for how to use presenters but having just read (Laravel View Presenters From Scratch), everything is clear!
Sorry for posting prematurely.

I am learning how to do simple tests on my application. Simply, I dont know how to get over the problem below.
Problem:
I am just trying to see, if my page is loading correctly by checking if site contain word "Send". Send is my button that is located in my view.
How can I check the view as a logged user?
My test function:
public function testSiteIsLoadingCorrectly()
{
$response = $this->get('/homepage');
$response->assertSee("Send");
}
After some research I got this function:
public function testSiteIsLoadingCorrectly() {
$user = User::factory()->create();
$response = $this->actingAs($user)
->withSession(['banned' => false])
->get('/');
$response->assertSee("Welcome on my page!");
}
It works great but only for "/". If I give another route, my console is showing a lot of text and finally it doesn't work.
How can I solve this?
assertSee() works bad with polish chars like ą,ę,ć etc...
That's the reason of all problems.
PS.
"Send" in Polish means "Wyślij"...
This is a basic issue, when submitting and performing a post, you normally want to avoid giving the user the chance to re-iterate the submit by refreshing or going back and forth with browser history.
(Backend re-submit, controls and checking is not questioned here. Of course they should be in place for security)
My solution was to have in Laravel web routes defined a post and a get route.
Like:
Route::post('/action', 'ActionController#doAction')->name('do.action');
Route::get('/action', 'ActionController#doActionConfirm')->name('do.action.confirm');
In ActionController something like:
public function doAction(Request $request)
{
....
return redirect()->route('do.action.confirm', [ 'data' =>
base64_encode(json_encode([
'action_id'=> $action_id,
'sent_to'=> $email,
'sent_success'=> $sent_success,
'sent_errors'=> $sent_errors,
]))]);
}
....
public function doActionConfirm(Request $request)
{
return view('confirmation')->with('data',$request->input('data'));
}
Then in my confirmation.blade.php get that $data decoded and displayed.
Is this the correct way to do it with Laravel?
What I don't like here:
is there's a better and more elegant way to forward data from the redirect()
is there a better way to manage get parameters to the GET route just to avoid people understanding and trying to inject unwanted data to the confirmation blade? (even if they will obtain nothing but no-sense views..because the page is doing nothing, it's simply displaying data in HTML blade)
I want to grab some data from a database and display on a layout page, I've basically started building a small CMS to get into Laravel and all has gone fine so far but now i'm at a wall, and can't find a solution.
I have a layout blade file like so: http://paste.laravel.com/1fB1 nothing majot but you will see i have used $page->meta_title etc in there and in my controller i have:
public function home()
{
$pages = Pages::all();
return View::make('frontend/home')->with('pages',$pages);
}
Which I have a pages model doing nothing else really like so:
class Pages extends Eloquent {
protected $table = 'pages';
}
So why is it trying to get property of non-object and I don't really want to use a foreach because this is going to be the frontend of my 'test' website so a foreach wouldn't suite.
You'll need to access these items as a multi-dimensional array if you don't want to loop through them.
$pages[0]['field_name_here']
or
$pages[1]['field_name_here']
Its a bit of a tough one to answer without knowing how you want your CMS to work.
For example, you could have a route as {pagename} in your routes.php file, then have a page controller where you would get the requested route from the variable passed in. This would then load the page you wanted using the variable
public function page( $pagename ) {
$page = Page::where('page_title', '=', $pagename)->first();
View::make('frontend/page', array( 'page' => $page ));
}
Using a route like that, and the controller, in your view you could use {{ $page->content }} to get the content of the requested page from the database and display it.
Hope this helps.
Edit: Example Route:
Route::get('{pagename}', 'PageController#page');
I am using Laravel 4.
I have an old url that needs to be routable. It doesn't really matter what it's purpose is but it exists within the paypal systems and will be called regularly but cannot be changed (which is ridiculous I know).
I realise that this isn't the format url's are supposed to take in Laravel, but this is the url that will be called and I need to find a way to route it:
http://domain.com/forum/index.php?app=subscriptions&r_f_g=xxx-paypal
(xxx will be different on every request)
I can't figure out how to route this with laravel, i'd like to route it to the method PaypalController#ipbIpn so i've tried something like this:
Route::post('forum/index.php?app=subscriptions&r_f_g={id}-paypal', 'PaypalController#ipbIpn');
But this doesn't work, infact I can't even get this to work:
Route::post('forum/index.php', 'PaypalController#ipbIpn');
But this will:
Route::post('forum/index', 'PaypalController#ipbIpn');
So the question is how can I route the url, as it is at the top of this question, using Laravel?
For completeness I should say that this will always be a post not a get, but that shouldn't really make any difference to the solution.
Use this:
Route::post('forum/{file}', 'PaypalController#ipbIpn');
And then in the controller, use
public function forum($file) {
$request = Route::getRequest();
$q = (array) $request->query; // GET
$parameters = array();
foreach($q as $key => $pararr) {
$parameters = array_merge($parameters, $pararr);
}
}
You can then access the get parameters via e.g.
echo $parameters['app'];
you can use route redirection to mask and ending .php route ex:
Route::get('forum/index', ['uses'=> 'PaypalController#ipbIpn']);
Route::redirect('forum/index.php', 'forum/index');
I was wondering if someone could help me out.
Im building a forum into my codeigniter application and im having a little trouble figuring out how i build the segments.
As per the CI userguide the uri is built as follows
www.application.com/CLASS/METHOD/ARGUMENTS
This is fine except i need to structure that part a bit different.
In my forum i have categories and posts, so to view a category the following url is used
www.application.com/forums
This is fine as its the class name, but i want to have the next segment dynamic, for instance if i have a category called 'mycategory' and a post by the name of 'this-is-my-first-post', then the structure SHOULD be
www.application.com/forums/mycategory/this-is-my-first-post
I cant seem to achieve that because as per the documentation the 'mycategory' needs to be a method, even if i was to do something like /forums/category/mycategory/this-is-my-first-post it still gets confusing.
If anyone has ever done something like this before, could they shed a little light on it for me please, im quite stuck on this.
Cheers,
Nothing is confusing in the document but you are a little bit confused. Let me give you some suggestions.
You create a view where you create hyperlinks to be clicked and in the hyperlink you provide this instruction
First Post
In the controller you can easily get this
$category = $this->uri->segment(3);
$post = $this->uri->segment(4);
And now you can proceed.
If you think your requirements are something else you can use a hack i have created a method for this which dynamically assign segments.
Go to system/core/uri.php and add this method
function assing_segment($n,$num)
{
$this->segments[$n] = $num;
return $this->segments[$n];
}
How to use
$this->uri->assign_segment(3,'mycategory');
$this->uri->assign_segment(4,'this-is-my-first-post');
And if you have error 'The uri you submitted has disallowed characters' then go to application/config/config.php and add - to this
$config['permitted_uri_chars'] = 'a-z 0-9~%.:_\-';
You could make a route that forwards to a lookup function.
For example in your routes.php add a line something like;
$route['product/(:any)/(:any)'] = "forums/cat_lookup/$1/$2";
This function would then do a database lookup to find the category.
...
public function cat_lookup($cat, $post) {
$catid = $this->forum_model->get_by_name($cat);
if ($catid == FALSE) {
redirect('/home');
}
$post_id = $this->post_model->get_by_name($post);
/* whatever else you want */
// then call the function you want or load the view
$this->load->view('show_post');
}
...
This method will keep the url looking as you want and handle any problems if the category does not exist.Don't forget you can store the category/posts in your database using underscores and use the uri_title() function to make them pretty,
Set in within config/routes.php
$route['song-album/(:any)/:num'] = 'Home/song_album/$id';
fetch in function with help of uri segment.
$this->uri->segment(1);
