I know create: makeDirectory(). Also, I know delete, copy, move (deleteDirectory, copyDirectory, moveDirectory). But, how can I verify if the folder exists with laravel. that´s my function
public function storeFile(Request $request)
{
$request->all();
$folders = $request->file01;
if($request->hasFile('file01'))
{
$request->file01->store('public/'.$folders);
return "Saved!";
}
}
You can use several methods.
With Laravel you can simply use File::isDirectory($dir). Laravel API
With PHP you can also just is is_dir, PHP Docs
you can use a php function: is_dir
is_dir($path)

I am using Laravel 8. My site's public directory is public_html and I have made the appropriate changed to the appservice provider:
public function register()
{
$this->app->bind('path.public', function() {
return base_path().'/public_html';
});
}
and changed the lfm is config to
'base_directory' => 'public_html',
The filemanager is uploading to the correct directory and making thumbnails in a subdirectory correctly, but it's view is a broken symbol.
I appreciate any help.
You have to bind the new storage path to the app instance. Please try this:
AppServiceProvider
public function register()
{
$this->app->instance('path.storage', base_path() . '/public_html');
}
Just get rid of the /laravel-filemanager/ prefix from the src URLs.
you have got the photos as a route.
example:
https://quislingmovie.com/photos/shares/6183cadfd8b51.jpg
i hope you can help me with my problem.
I have a Laravel application and i wanna optimize all my images.
I use a controller for that, but i have a lot of images, and i get execution_maxim_time_exceed.
I think, the best way to do that is to creat an artisan command.
So, i creat my with php artisan make:command Name command:example.
After, I move my code from controller to handle() from artisan command.
I can use Storage:move($oldPath, $newPath), but i can't use Image:make($filePath).
My file storage is "storage/app/images/image.png" and filePath is 'images/image.png'
When i use the controller, the method isFilePath() from Intervention\Image\AbstractDecoder return true, but in artisan command return false.
Method isFilePath() call the function is_file()
public function isFilePath()
{
if (is_string($this->data)) {
try {
return is_file($this->data);
} catch (\Exception $e) {
return false;
}
}
return false;
}
Why i get false from the function is_file() with the same path for file in artisan command, and in controller i get true? (for the same path).
Thanks
Ok, i found the solution.
In the controller is_file('images/image.png') return true, but in the cli, i need to use the full path
so, in CLI i use 'storage/app/images/image.png'.
I have two controller file homecontroller and backendcontroller. What is the best way to create global function and access it from both files?
I found here Arian Acosta's answer helpful but I wonder if there is an easiest way. I would appreciate any suggestions.
Solution
One way to do this is to create a class and use its instance, this way you can not only access the object of the class within a controller, blade, or any other class as well.
AppHelper file
In you app folder create a folder named Helpers and within it create a file name AppHelper or any of your choice
<?php
namespace App\Helpers;
class AppHelper
{
public function bladeHelper($someValue)
{
return "increment $someValue";
}
public function startQueryLog()
{
\DB::enableQueryLog();
}
public function showQueries()
{
dd(\DB::getQueryLog());
}
public static function instance()
{
return new AppHelper();
}
}
Usage
In a controller
When in a controller you can call the various functions
public function index()
{
//some code
//need to debug query
\App\Helpers\AppHelper::instance()->startQueryLog();
//some code that executes queries
\App\Helpers\AppHelper::instance()->showQueries();
}
In a blade file
Say you were in a blade file, here is how you can call the app blade helper function
some html code
{{ \App\Helpers\AppHelper::instance()->bladeHelper($value) }}
and then some html code
Reduce the overhead of namespace (Optional)
You can also reduce the overhead of call the complete function namespace \App\Helpers by creating alias for the AppHelper class in config\app.php
'aliases' => [
....
'AppHelper' => App\Helpers\AppHelper::class
]
and in your controller or your blade file, you can directly call
\AppHelper::instance()->functioName();
Easy Solution:
Create a new Helpers folder in your app directory.
Create a php file named your_helper_function.php in that Helpers directory.
Add your function(s) inside your_helper_function.php
function your_function($parameters){
//function logic
}
function your_another_function($parameters){
//function logic
}
Add this file to the Files key of your composer.json like
"autoload": {
...
"files": [
"app/Helpers/your_helper_function.php"
]
...
}
Finally, regenerate composer autoload files. (Run this in your project directory)
composer dump-autoload
That's it! and now you can access your_function() or your_another_function() in any part of your Laravel project.
If you still have any confusion, check my blog post on how to do this:
How to Add a Global Function in Laravel Using Composer?
Updated:
Step 1
Add folder inside app folder
app->Helper
Step 2
add php Class inside Helper folder
Eg. Helper.php
Add namespace and class to the Helper.php
namespace App\Helper;
class Helper
{
}
Register this Helper.php into config/app.php file
'aliases' => [
....
'Helper' => App\Helper\Helper::class
]
Now, write all the functions inside Helper.php and it will be accessible everywhere.
How to access from Controller?
Step 1 - Add a namespace at top of the controller.
use App\Helper\Helper;
Step 2 - Call function - Assume there a getInformation() inside the Helper Class.
$information = Helper::getInformation()
In your Controller.php which extends BaseController, you can create a function like;
public function data($arr = false)
{
$data['foo'] = 'bar';
return array_merge($data,$arr);
}
And from any controller when you send a data to a view;
public function example()
{
$data['smthg'] = 'smthgelse';
return view('myView',$this->data($data));
}
The data in the the main controller can be accessed from all controllers and blades.
The Laravel Service Provider way
I've been using global function within Laravel for a while and I want to share how I do it. It's kind of a mix between 2 answers in this post : https://stackoverflow.com/a/44021966/5543999 and https://stackoverflow.com/a/44024328/5543999
This way will load a file within a ServiceProvider and register it within your Laravel app.
Where is the difference, the scope, it's always about the scope.
Composer //Autload whitin composer.json method
|
|--->Laravel App //My method
|
|--->Controller //Trait method
|--->Blade //Trait method
|--->Listener //Trait method
|--->...
This is a really simplist way to explain my point, all three methods will achieve the purpose of the "Global function". The Traits method will need you to declare use App\Helpers\Trait; or App\Helpers\Trait::function().
The composer and service provider are almost about the same. For me, they answer better to the question of what is a global function, because they don't require to declare them on each place you want to use them. You just use them function(). The main difference is how you prefer things.
How to
Create the functions file : App\Functions\GlobalFunctions.php
//App\Functions\GlobalFunctions.php
<?php
function first_function()
{
//function logic
}
function second_function()
{
//function logic
}
Create a ServiceProvider:
//Into the console
php artisan make:provider GlobalFunctionsServiceProvider
Open the new file App\Providers\GlobalFunctionsServiceProvider.php and edit the register method
//App\Providers\GlobalFunctionsServiceProvider.php
public function register()
{
require_once base_path().'/app/Functions/GlobalFunctions.php';
}
Register your provider into App\Config\App.php wihtin the providers
//App\Config\App.php
'providers' => [
/*
* Laravel Framework Service Providers...
*/
Illuminate\Auth\AuthServiceProvider::class,
...
Illuminate\Validation\ValidationServiceProvider::class,
Illuminate\View\ViewServiceProvider::class,
App\Providers\GlobalFunctionsServiceProvider::class, //Add your service provider
Run some artisan's commands
//Into the console
php artisan clear-compiled
php artisan config:cache
Use your new global functions
//Use your function anywhere within your Laravel app
first_function();
second_function();
Laravel uses namespaces by default. So you need to follow the method described in that answer to setup a helper file.
Though in your case you want to access a method in different controllers. For this there's a simpler way. Add a method to you base controller app/Http/Controllers/Controller.php and you can access them in every other controller since they extend it.
// in app/Http/Controllers/Controller.php
protected function dummy()
{
return 'dummy';
}
// in homecontroller
$this->dummy();
There are a few ways, depending on the exact functionality you're trying to add.
1) Create a function inside Controller.php, and make all other controller extend that controller. You could somewhat compair this to the master.blade.php
2) Create a trait, a trait can do a lot for you, and keeping ur controllers clean. I personally love to use traits as it will look clean, keep my Controller.php from being a mess with tons of different lines of code.
Creating a global function
create a Helpers.php file under a folder, let's name it 'core'.
core
|
-- Helpers.php
namespace Helpers; // define Helper scope
if(!function_exists('html')) {
function html($string) {
// run some code
return $str;
}
}
In your composer.json
"autoload": {
"psr-4": {
},
"files": [
"core/Helpers.php"
]
}
in the file that you want to use it
// the " use " statement is not needed, core/Helpers is loaded on every page
if(condition_is_true) {
echo Helpers\html($string);die();
}
Remove the namespace in Helpers.php if you want to call your function without the need to prefix namespace. However I advise to leave it there.
Credit: https://dev.to/kingsconsult/how-to-create-laravel-8-helpers-function-global-function-d8n
By using composer.json and put the function containing file(globalhelper.php) to the autoload > files section, then run
composer dump-autoload
You can access the function inside the file(globalhelper.php) without having to calling the class name, just like using default php function.
I need to check if a Laravel Console Command exists and if it is in the protected command var to call them.
I need to call them from another Laravel console command. And I want to know if there are something like exists_command('mycommand:foo')
There are any way to achieve this?
Tested and working.
function command_exists($name)
{
return array_has(\Artisan::all(), $name);
}
if (command_exists('config:cache')) {
// success
}
Though #Sandeesh is right, we can check in this way:
function exists_command($name)
{
return array_key_exists($name, \Artisan::all());
}
if (exists_command('mycommand:foo')) {
// success
}
even in a shorter way,
function exists_command($name)
{
return $this->getApplication()->has($name);
}
php artisan list
Will bring up all possible artisan commands. There is a 'command' subsection with your own created commands.
You would call them as follows
php artisan command:MyCreatedCommand
Edit: To check if a command exists in your project you can use php class_exists function
if(class_exists('App\Console\Commands\MyCommandName')){
//Do whatever
}
im new in laravel 5.2, I just want to ask how you can catch a link that came from uploads like: http://sitename.com/uploads/59128.txt? I want to redirect them to login page if they tried to access any of route or link that came from uploads/{any filename}.
Yes you can achieve by protecting your route with auth middleware,
make a small FileController
class FileController extends Controller {
public function __construct()
{
$this->middleware('auth');
}
public function getFile($filename)
{
return response()->download(storage_path($filename), null, [], null);
}
}
and then in routes.php
Route::get('file/{filename}', 'FileController#getFile')->where('filename', '^[^/]+$');
And that's it. Now, your authenticated users can download files from storage folder (but not its subfolders) by calling http://yoursite.com/file/secret.jpg. Add you can use this URL in src attribute of an image tag.
answer's original source!
#xerwudjohn simple you can't.
When this file is in the public folder, everyone can access it whitout being logged in.
One method I tried for some minutes, create a new route:
Route::group(['middleware' => ['web', 'auth']], function () {
Route::get('/download/{id}', 'DownloadController#showFile');
});
create the function showFile in the DonwloadController
public function showFile($id)
{
return redirect('/image/'.$id.'.txt');
}
or use a Model to read uniqueIds out of any table and get the realfile name.
Cheers
