Laravel 5 - 我应该在哪里写这个函数，以及如何编写？

Goodevening,

I have an overview page where I display all my project items.

I have a model (Project.php) a controller (ProjectController) where I send the variable $project (this includes all the information for each project) to the specific view.

Note: Each project has a own row in the database. (Quit obvious I guess)

Now I also have a table 'tasks' related to a specific project. In my view I wanna display how much of the total tasks are 'done'. (This is doing with the column 'done' (true/false, boolean)).

Now because I have a foreach function in my view (to display each individuele project) I can make the function in the view. But the Laravel framework is there for reasons. And writing out a lot of php in a view isn't the right way.

But, where should I make this function? And how can I use it in my foreach (in the view). Ofcourse I can make a new foreach in my model or controller and send that variable to my view. But then I can't use that one in my view-foreach as things will get mixed up.

I don't know how/where I can set up a function like this on a clean way.

Kinds regards,

Dylan

You can create a function in app directory(forexample app/Helpers/), or wherever you want and name it yourHelperFunction.php.

After creating that file, Laravel won’t recognize the file until it is registered inside composer.json file. Add files array inside autoload section.

.
.
.
"autoload": {
   "files":[
     "app/Helpers/yourHelperFunction.php"
   ]
}
.
.
.

then do composer dump autoload and you are ready to use the function inside the blade

Use Blade engine, not Core PHP loops. It is wise to use blade engine then core php codes.

You can see the documentation Laravel 5 Blade Template

Thanks for the help. I've figured it out (I guess?).

I have this function in my Project Model.

    public function getTaskDonePercentage($id) {
    $tasks = Task::where('project_id', $id)->count();

    $tasks_done = Task::where([
      ['project_id', $id],
      ['status', 'done']
    ])->count();

    if ($tasks_done > 0) {
      $calc = ($tasks_done / $tasks) * 100;
    }
    else {
      $calc = '100';
    }

    return round($calc) . '%';
  }

Then in my view I just call the function in the foreach like:

@foreach
{{ $project_item->getTaskDonePercentage($project_item->id) }}
@endforeach

Tbh I still wanna know if this approach is a good one. (Or, if not, why it isnt?).

Thanks!
