i would like to know how can i add extra column in laravel collection, return from database. for instance.
User Model
User->id
User->name
Reservation Model
Reservation->user_id
Reservation->id
now
$users = User::all();
$user_reservation = Reservation::all();
foreach ($users as $user)
{
foreach ($user_reservation as $ur)
{
if ($user->id == $ur->user_id)
{
//Add extra column in to the users model
}
}
}
Laravel has a something called $appends with Accessors. how to use it
Define $append in the model where you want to add custom collection. in my case User model
class User extends Model{
protected $appends = ['user_eservation'];
public function getUserReservations($id)
{
return User::where('id', $id)->first();
}
public function getUserReservationAttribute()
{
return $this->getUserReservations(Auth::user()->id);
}
}
and now you can call the custom attribute which is not available in the database , by calling the getUserReservatoin function.
for instance
$users = User::all();
$user_reservation = Reservation::all();
foreach ($users as $user)
{
foreach ($user_reservation as $ur)
{
if ($user->id == $ur->user_id)
{
$user->getUserReservations();
}
}
}
$user->push(['extra_column' => $value]);

i want to find post by slug also in url ..
but the comments must be found by post_id
Controller
public function post($slug,$id)
{
$post = Post::where('slug',$slug)->first();
$comments = Comment::where('post_id',$id)->get();
return view('content.post',compact('post','comments'));
}
Route
Route::get('post/{slug}', 'PagesController#post')->name('post.show');
Route::get('post/{slug}', 'PagesController#post')->name('post.show');
public function post($slug)
{
$post = Post::where('slug',$slug)->first();
$comments = Comment::where('post_id',$post->id)->get();
return view('content.post',compact('post','comments'));
}
Here you go:
Get post_id from the $post itself.
public function post($slug){
$post = Post::where('slug',$slug)->first();
$comments = Comment::where('post_id',$post->id)->get();
...
}
You can use Route Model Binding to ensure that routes will find your model based on the provided key.
Your Post model will require that you add the following method:
public function getRouteKeyName()
{
return 'slug';
}
Then, in your routes, you can just refer the model directly, and binding will happen automatically:
public function post(App\Post $post)
{
$comments = Comment::where('post_id',$post->id)->get();
return view('content.post',compact('post','comments'));
}
This enables you to to use the following route:
Route::get('post/{post}', 'PagesController#post')->name('post.show');
Now, additionally, to ease up your reference of the comments, add them as relations to your Post model:
public function comments()
{
return $this->hasMany(Comment::class);
}
and your Comment model:
public function post()
{
return $this->belongsTo(Post::class);
}
This will allow you to shorten your controller method even more:
public function post(App\Post $post)
{
return view('content.post',compact('post'));
}
and in your Blade view do the following instead:
#foreach($post->comments as $comment)
From: {{ $comment->name }} blah blha
#endforeach
in web.php:
Route::get('post/{slug}', 'PagesController#post')->name('post.show');
in controller:
public function post($slug)
{
$post = Post::where('slug',$slug)->first();
$comments = Comment::where('post_id',$post->id)->get(); //use founded_post_id to find it's comments
return view('content.post',compact('post','comments'));
}
I've taken over the code from another developer, and I'm quite confused and stuck: one controller I can call the class method CLASSS::method perfectly OK. the other Controller has a copy of the orginal code and modified. On the second one, I get the "non-static method" error.

To my untutored eye, they look identical, yet one works and the other doesn't. Apologies in advance for the volume of code, but I don't know which parts are affecting what. I suspect it's somethng to do with an imported class, but I'm lost frankly :-D
Site has a Facade while Organisation does not.
Facades (from the docs) provide a "static" interface to classes that are available in the application's service container.
This has got to be a simple fix, as I have done this many times before. But as it stands I am completely stumped. I use the following code to save a parent object Unknown_Tag and its many children.
Method:
public function saveUnknown(Request $request)
{
$url = $request->url;
$tag = new Unknown_Tag();
$tag->url = $url;
$protocol =
substr($url, 0, strpos($url, ':'));
$tag->protocol = $protocol;
$domain =
parse_url($url, PHP_URL_HOST);
$tag->domain = $domain;
$tag->save();
//get the path
$Path = parse_url($url, PHP_URL_PATH);
if ($Path) {
$splitPath = substr($Path, 1);
$paths = explode('/', $splitPath);
foreach ($paths as $p) {
$path = new Path();
$path->path = $p;
$tag->Paths()->save($path);
}
}
//get Queries
$splitQuery = parse_url($url, PHP_URL_QUERY);
if ($splitQuery) {
$queries = explode('&', $splitQuery);
foreach ($queries as $q) {
$query = new Query();
$q = substr($q, 0, strpos($q, '='));
IF (SUBSTR($q, -1) != ' ') {
$q .= ' ';
}
$query->var = $q;
$value = $q = preg_replace('/^[^=]*:/', '', $q);
$query->value = $value;
$tag->Queries()->save($query);
}
}
}
The Parent Object
class Unknown_Tag extends Model
{
protected $table = 'unknown_tags';
public $timestamps = false;
public function Paths()
{
return $this->hasMany('App\Path', 'tag_id', 'ID');
}
public function Queries()
{
return $this->hasMany('App\Query', 'tag_id', 'ID');
}
}
The Child objects
class Query extends Model
{
protected $table = 'queries';
public $timestamps = false;
public function Tag()
{
return $this->belongsTo('App\Unknown_Tag', 'tag_id', 'ID');
}
}
class Path extends Model
{
protected $table = 'paths';
public $timestamps = false;
public function Tag()
{
return $this->belongsTo('App\Unknown_Tag', 'tag_id', 'ID');
}
}
When I run all this via a post request, The Parent and all the children are saved properly, but all the child objects have a foreign key that is set to null. If I manually change the foreign key to what it should be, everything works just fine, so I am fairly sure this is not a problem with my database. Can anyone see the obvious that I am missing here?
EDIT:Just to be clear, this returns no errors
If anyone ever sees this, laravel assumes the default primary key is 'id'. I had set mine to 'ID', so I had to let laravel know by using
protected $primaryKey = 'ID';
in my Unknown_tag definition
what is the professional way insert record in database.
i am using laravel 5.2.
i'm new in laravel.
class students extends Controller
{
public function index()
{
$insertData = array(
"name" => Input::get("name"),
"detail" => Input::get("detail"),
"token_key" => Input::get("_token")
);
return view('student');
}
public function fees()
{
$record = array(
"p_name" => Input::get("name"),
"p_fees" => Input::get("fees"),
"p_detail" => Input::get("detail")
);
return view('fee');
}
}
stander able way?
You should use mass assignment. Fill $fillable array inside your model and use this:
Model::create($insertData);
public function store_student(Request $request)
{
$student = new Student;
$student->name = $request->name;
$student->detail = $request->details
$student->save();
return view('student');
}
public function store_fee(Request $request)
{
$fee = new Fee;
$fee->p_name = $request->name;
$fee->p_fee = $request->fees;
$fee->p_detail = $request->details
$fee->save();
return view('fee');
}
I suggest you to read this from Laravel official guide.
However you can do it like this:
DB::table('tablename')->insert($insertData);
I create a core class named MY_Model that extends CI_Model. In this class, I create a method chaining to get all record with pagination like this :
// Take record with paging.
public function get_all_paged()
{
// get argument that passed
$args = func_get_args();
// get_all_paged($offset)
if (count($args) < 2) {
$this->get_real_offset($args[0]);
$this->db->limit($this->_per_page, $this->_offset);
}
// get_all_paged(array('status' => '1'), $offset)
else {
$this->get_real_offset($args[1]);
$this->db->where($args[0])->limit($this->_per_page, $this->_offset);
}
// return all record
return $this->db->get($this->_tabel)->result();
}
So , I just used like this on my controller,
for example
public function index($offset = NULL) {
$karyawan = $this->karyawan->get_all_paged($offset); //get all
}
I am realy confuse to get all record using join, I know join in CI like this :
public function get_all_karyawan() {
$this->db->select('tb_1 , tb_2');
$this->db->from('tb_1');
$this->db->join('tb_2', "where");
$query = $this->db->get();
return $query->result();
}
How to make it into chain in MY_Model?
Any help it so appreciated ...
The good thing in query builder, you can chain your db methods, till get(). So you can define, selects, where queries, limits in different ways.
For example:
public function category($category)
{
$this->db->where('category_id', $category);
return $this;
}
public function get_posts()
{
return $this->db->get('posts')->result();
}
And you can get all posts:
$this->model->get_posts();
Or by category:
$this->model->category(2)->get_posts();
So upon this, in your model:
public function get_all_karyawan() {
$this->db->select('tb_1 , tb_2');
$this->db->join('tb_1', "where");
// Here you make able to chain the method with this
return $this;
}
In your controller:
public function index($offset = NULL) {
$karyawan = $this->karyawan->get_all_karyawan()->get_all_paged($offset);
}
