Hi i am using laravel Goutte package to crawl some specific data for data analysis in my project while i am applying the filter some of td is return the right result while some is not return result anyone have the idea please help my controller code is
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Goutte;
use Goutte\Client;
use App\Http\Requests;
class MapController1 extends Controller
{
//
public function index()
{
$crawler = Goutte::request('GET', 'http://www.upsldc.org/real-time-data');
$crawler->filter('body')->each(function ($node) {
echo "<pre>";
//var_dump($node->text());
echo $node->filter('td')->eq(0)->text();
echo $node->filter('td.up_schedule')->text();
echo $node->filter('td')->eq(2)->text();
});
}
}
it is return Schedule (MW)Drawl (MW) but this echo $node->filter('td.up_schedule')->text(); row is return nothing. Thanks in advance

I am having issues it says Request is undefined same goes for DB.
public function edit(Request $request,$id) {
$name = $request->input('stud_name');
DB::update('update student set name = ? where id = ?',[$name,$id]);
echo "Record updated successfully.<br/>";
echo 'Click Here to go back.';
}
Looks like you're missing use statements that tell your script where to find these. Add
use Illuminate\Http\Request;
use Illuminate\Support\Facades\DB;
in your file after namespace ...
I have this route:
Route::get('/test',['as'=>'test','custom_key'=>'custom_value','uses'=>'TestController#index'])
I've been tried to use $routeProfile=route('test');
But the result is returned url string http://domain.app/test
I need ['as'=>'test','custom_key'=>'custom_value'] so that I can get the $routeProfile['custom_key']
How can I get 'custom_value' based on route name ?
For fastest way, now I use this for my question:
function routeProfile($routeName)
{
$routes = Route::getRoutes();
foreach ($routes as $route) {
$action = $route->getAction();
if (!empty($action['as']) && $routeName == $action['as']) {
$action['methods'] = $route->methods();
$action['parameters'] = $route->parameters();
$action['parametersNames'] = $route->parametersNames();
return $action;
}
}
}
If there's any better answer, I will be appreciate it.
Thanks...
Try this:
use Illuminate\Support\Facades\Route;
$customKey = Route::current()->getAction()['custom_key'];
I believe you are looking for a way to pass variable to your route
Route::get('/test/{custom_key}',[
'uses'=>'TestController#index',
'as'=>'test'
]);
You could generate a valid URL like so using
route('test',['custom_key'=>'custom_key_vale'])
In your view:
<a href="{route('test',['custom_key'=>'custom_key_vale'])}"
In your controller method:
....
public function test(Request $request)
{
$custom_key = $request->custom_key;
}
....
You can try one of the below code:
1. Add use Illuminate\Http\Request; after namespace line code
public function welcome(Request $request)
{
$request->route()->getAction()['custom_key'];
}
2. OR with a facade
Add use Route; after namespace line code
and use below into your method
public function welcome()
{
Route::getCurrentRoute()->getAction()['custom_key'];
}
Both are tested and working fine!
I been trying to figure this out for some time now. Basically i got 2 models ' Recipe ', ' Ingredient ' and one Controller ' RecipeController ' .
I'm using Postman to test my API. When i go to my get route which uses RecipeController#getRecipe, the return value is as per the pic below:
Return for Get Route
If i want the return value of the get route to be in the FORMAT of the below pic, how do i achieve this? By this i mean i don't want to see for the recipes: the created_at column, updated_at column and for ingredients: the pivot information column, only want name and amount column information.
Return Value Format I Want
Recipe model:
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Recipe extends Model
{
protected $fillable = ['name', 'description'];
public function ingredients()
{
return $this->belongsToMany(Ingredient::class,
'ingredient_recipes')->select(array('name', 'amount'));
}
}
Ingredient Model:
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Ingredient extends Model
{
protected $fillable = ['name', 'amount'];
}
RecipeController
<?php
namespace App\Http\Controllers;
use App\Ingredient;
use App\Recipe;
use Illuminate\Http\Request;
class RecipeController extends Controller {
public function postRecipe(Request $request)
{
$recipe = new Recipe();
$recipe->name = $request->input('name');
$recipe->description = $request->input('description');
$recipe->save();
$array_ingredients = $request->input('ingredients');
foreach ($array_ingredients as $array_ingredient) {
$ingredient = new Ingredient();
$ingredient->name = $array_ingredient['ingredient_name'];
$ingredient->amount = $array_ingredient['ingredient_amount'];
$ingredient->save();
$recipe->ingredients()->attach($ingredient->id);
}
return response()->json(['recipe' => $recipe . $ingredient], 201);
}
public function getRecipe()
{
$recipes = Recipe::all();
foreach ($recipes as $recipe) {
$recipe = $recipe->ingredients;
}
$response = [
'recipes' => $recipes
];
return response()->json($response, 200);
}
API Routes:
Route::post('/recipe', 'RecipeController#postRecipe')->name('get_recipe');
Route::get('/recipe', 'RecipeController#getRecipe')->name('post_recipe');
Thanks Guys!
I think your best solution is using Transformer. Using your current implementation what I would recommend is fetching only the needed field in your loop, i.e:
foreach ($recipes as $recipe) {
$recipe = $recipe->ingredients->only(['ingredient_name', 'ingredient_amount']);
}
While the above might work, yet there is an issue with your current implementation because there will be tons of iteration/loop polling the database, I would recommend eager loading the relation instead.
But for the sake of this question, you only need Transformer.
Install transformer using composer composer require league/fractal Then you can create a directory called Transformers under the app directory.
Then create a class called RecipesTransformer, and initialize with:
namespace App\Transformers;
use App\Recipe;
use League\Fractal\TransformerAbstract;
class RecipesTransformer extends TransformerAbstract
{
public function transform(Recipe $recipe)
{
return [
'name' => $recipe->name,
'description' => $recipe->description,
'ingredients' =>
$recipe->ingredients->get(['ingredient_name', 'ingredient_amount'])->toArray()
];
}
}
Then you can use this transformer in your controller method like this:
use App\Transformers\RecipesTransformer;
......
public function getRecipe()
{
return $this->collection(Recipe::all(), new RecipesTransformer);
//or if you need to get one
return $this->item(Recipe::first(), new RecipesTransformer);
}
You can refer to a good tutorial like this for more inspiration, or simply go to Fractal's page for details.
Update
In order to get Fractal collection working since the example I gave would work if you have Dingo API in your project, you can manually create it this way:
public function getRecipe()
{
$fractal = app()->make('League\Fractal\Manager');
$resource = new \League\Fractal\Resource\Collection(Recipe::all(), new RecipesTransformer);
return response()->json(
$fractal->createData($resource)->toArray());
}
In case you want to make an Item instead of collection, then you can have new \League\Fractal\Resource\Item instead. I would recommend you either have Dingo API installed or you can follow this simple tutorial in order to have in more handled neatly without unnecessary repeatition
I work with laravael 5.3.9 .
In my controller I use
Illuminate\Support\Facades\Input;
But when I try to get input from a user form using method post like that :
function add(){
$fullName = Input::post('fullName' , 'test');
I get this error .
the only method that Input class has is "get" .
I dont want that in my system I want to work with method post , delete , put ....
I guess, Input::post method is not used with L5.3. Use the Request facade OR $request to get your input variable.
Try this in your controller
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
class area_owners extends Controller
{
function add(Request $request)
{
// I assume all these input variable have same name in you FORM.
$fullName = $request->input('fullName');
$smsCode = $request->input('smsCode');
$authorizationId = $request->input('authorizationId');
$areaNumber = $request->input('areaNumber');
$neigh_project_Id = $request->input('neigh_project_Id');
$area_owners = DB::table('area_owners')
->insert(['fullName'=>$fullName,
'smsCode'=>$smsCode,
'authorizationId'=>$authorizationId,
'areaNumer'=>$areaNumber,
'neigh_project_Id'=>$neigh_project_Id]);
return view('area_owners_add', ['area_owners' => $area_owners]);
}
}
Let me know if it helps.
Currently following a Laravel 4 book on writing tests, the following returns no output from PHPUnit if the function is named link_to(), but does return the result if it is named something else like link_tox(). Why is this?
app/helpers.php
<?php
function link_to($url, $body) {
$url = url($url);
return "<a href='{$url}'>{$body}</a>";
}
app/tests/ExampleTests.php
<?php
class FunctionsTest extends TestCase {
public function testGeneratesAnchorTag() {
$actual = link_to('dogs/1', 'Show Dog');
$expected = "<a href='http://localhost/dogs/1'>Show Dog</a>";
$this->assertEquals($expected, $actual);
}
}
Laravel already has a link_to function.
