how to call ssh from vs code

 To call SSH from VS Code, you can use the built-in Remote Development extension. This extension allows you to open a remote folder or workspace over SSH, so that you can edit files, run commands, and debug applications on a remote machine.

Here are the steps to use the Remote Development extension to connect to a remote machine over SSH:

Install the Remote Development extension from the VS Code marketplace.

Open VS Code and click on the Remote Explorer icon in the left sidebar.

Click the "+" icon at the top of the Remote Explorer panel, then select "Connect to Host..."

In the "Connect to Host" dialog, enter the SSH connection details for your remote machine, including the hostname or IP address, port number, and username.

Click "Connect", and VS Code will establish an SSH connection to the remote machine.

Once the connection is established, you can open a remote folder or workspace by clicking the "+" icon in the Remote Explorer panel and selecting "Open Folder..." or "Open Workspace..."

You can then edit files, run commands, and debug applications on the remote machine as if you were working locally.

Note that in order to use the Remote Development extension over SSH, you must have SSH access to the remote machine and SSH client tools installed on your local machine.

how to add translation in foreach list into laravel blade

 To add translations to a foreach loop in Laravel Blade, you can use the @lang directive to translate each item in the loop. Here is an example:

@foreach($items as $item)
    <li>@lang('messages.' . $item->name)</li>
@endforeach

In this example, the items variable contains a collection of objects with a name attribute. The @lang directive is used to translate each item's name by passing the translation key to the trans function. The translation key is constructed using the dot notation and the name attribute value of each item.

Assuming that you have defined the translations in your language files under the messages namespace, the @lang directive will automatically translate the item's name based on the current locale. If a translation is not available for the current locale, the original string will be returned.

how to add custom field in plugin wordpress

To add a custom field in a WordPress plugin, follow these steps:

Define the field: Determine what kind of field you want to add, and define its parameters. For example, you might want to add a text input field for a custom URL, with a label of "Custom URL". You'll need to decide on the field's name, ID, label, default value, and any other necessary attributes.

Add the field to the plugin: In your plugin code, create a function that adds the custom field. You can use the add_meta_box() function to create a custom metabox, which will contain your custom field. Here's an example:

function myplugin_add_custom_field() {
    add_meta_box(
        'myplugin_custom_url',
        'Custom URL',
        'myplugin_render_custom_url',
        'post',
        'normal',
        'default'
    );
}

function myplugin_render_custom_url($post) {
    $custom_url = get_post_meta($post->ID, '_myplugin_custom_url', true);
    ?>
    <label for="myplugin_custom_url">Custom URL</label>
    <input type="text" name="myplugin_custom_url" id="myplugin_custom_url" value="<?php echo esc_attr($custom_url); ?>">
    <?php
}
add_action('add_meta_boxes', 'myplugin_add_custom_field');

This code creates a metabox with the ID myplugin_custom_url, a title of "Custom URL", and a callback function of myplugin_render_custom_url. The myplugin_render_custom_url function displays the custom field, which is a text input field with a name of myplugin_custom_url. This function also retrieves any existing custom URL value for the current post, and populates the field with that value.

Save the field value: When the post is saved, you'll need to save the value of your custom field. You can use the save_post hook to do this. Here's an example:

function myplugin_save_custom_field($post_id) {
    if (isset($_POST['myplugin_custom_url'])) {
        update_post_meta($post_id, '_myplugin_custom_url', sanitize_text_field($_POST['myplugin_custom_url']));
    }
}
add_action('save_post', 'myplugin_save_custom_field');

This code uses the update_post_meta() function to save the value of the custom field to the post's metadata. The field's value is retrieved from $_POST, and sanitized using the sanitize_text_field() function.

 Your plugin now has a custom field that can be used to store and display additional information for posts.

How to add laravel translation

To add translations in Laravel, follow these steps:

Create a new language file: In Laravel, translation strings are typically stored in language files. You can create a new language file by running the following Artisan command in the terminal: 


php artisan make:lang {language_code} --json

Replace {language_code} with the ISO 639-1 language code of the language you want to add translations for. For example, if you want to add translations for French, you would use php artisan make:lang fr --json.

Add translation strings: Open the language file you just created in the resources/lang directory and add your translation strings in JSON format. For example:

{
    "welcome": "Bienvenue",
    "hello": "Bonjour"
}

Here, welcome and hello are the translation keys and Bienvenue and Bonjour are the translated strings for French.

Use the trans function to translate strings: In your views or controllers, you can use the trans function to translate strings. For example


<h1>{{ trans('messages.welcome') }}</h1>

Here, messages.welcome is the translation key for the Bienvenue string.

Change the application locale: By default, Laravel uses the en locale. To change the application locale to the language you just added translations for, add the following code to the AppServiceProvider:

use Illuminate\Support\Facades\App;
use Illuminate\Support\Facades\Config;
use Illuminate\Support\Facades\Session;

public function boot()
{
    $locale = Session::get('locale', Config::get('app.locale'));
    App::setLocale($locale);
}

This code sets the application locale to the language stored in the locale session variable, or the default app.locale if the session variable is not set.

Set the language in the session: Finally, you can set the language in the session by creating a route or controller method that sets the locale session variable. For example:

public function setLocale($locale)
{
    Session::put('locale', $locale);
    return redirect()->back();
}


This method sets the locale session variable to the language code passed in the URL parameter and redirects the user back to the previous page.

That's it! Your Laravel application now supports translations for the language you just added.


laravel how to keep same file or form for add edit form details

  Here's one approach you can take:

Create a form view file that contains the form fields you want to display for both adding and editing data.

In your controller method for adding data, pass an empty instance of the model associated with the form to the view.

For example, if you have a Post model and a create method in your controller, you can pass an empty instance of the Post model to the view like this

public function create()
{
    $post = new Post();
    return view('posts.form', compact('post'));
}

In your controller method for editing data, retrieve the data to be edited and pass it to the same form view.

For example, if you have an edit method in your controller, you can retrieve the Post to be edited and pass it to the same form view like this:



public function edit($id)
{
    $post = Post::find($id);
    return view('posts.form', compact('post'));
}

In the form view, use the $post variable to populate the form fields.

For example, if you have a title field in your form, you can populate it like this:


<input type="text" name="title" value="{{ old('title', $post->title) }}">

The old() function is used to display the previously submitted value for the field (if there is one), and the $post->title variable is used to display the existing value (if you're editing an existing post).

In your form submission handler, use the $post variable to either create a new record or update an existing one.

For example, if you have a store method in your controller, you can use the $post variable to create a new post like this:

public function store(Request $request)
{
    $post = new Post();
    $post->title = $request->input('title');
    // set other fields here
    $post->save();
    return redirect()->route('posts.index');
}

And you can use the $post variable to update an existing post like this:

public function update(Request $request, $id)
{
    $post = Post::find($id);
    $post->title = $request->input('title');
    // set other fields here
    $post->save();
    return redirect()->route('posts.index');
}


That's a basic example of how you can use the same form file for adding and editing data in Laravel.

php call function using ajax

To call a PHP function using AJAX, you can follow these steps:

Create a PHP file that contains the function you want to call. For example, let's create a file called functions.php and define a function called myFunction()

<?php

function myFunction() {
    // your code here
}

?>

In your HTML file, add the following code to include jQuery library:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>

Add an event listener to an element on your HTML page that will trigger the AJAX call. For example, let's add a button with an ID of myButton


<button id="myButton">Call myFunction</button>

Add the following JavaScript code to make the AJAX call when the button is clicked:

<script>
    $(document).ready(function(){
        $("#myButton").click(function(){
            $.ajax({
                url: "functions.php",
                type: "POST",
                data: {
                    functionName: "myFunction"
                },
                success: function(response) {
                    // handle success response
                },
                error: function(xhr, status, error) {
                    // handle error response
                }
            });
        });
    });
</script>


This code sends a POST request to the functions.php file, passing the name of the function you want to call as a parameter in the data object.


Finally, in the functions.php file, you can retrieve the function name from the POST request and call the corresponding function:

<?php

if(isset($_POST['functionName'])) {
    $functionName = $_POST['functionName'];
    if(function_exists($functionName)) {
        call_user_func($functionName);
    }
}

?>


This code checks if a function name was passed in the POST request, and if so, it checks if the function exists and calls it using the call_user_func() function.


Note that this is a simple example and you should add appropriate error handling and security measures depending on the specific use case.

Laravel create a api with sactum

To create a Laravel API with Sanctum, you can follow these steps:

Install Laravel Sanctum: 


composer require laravel/sanctum

Publish the Sanctum configuration and migration files:


php artisan vendor:publish --provider="Laravel\Sanctum\SanctumServiceProvider"

Run the Sanctum migrations:


php artisan migrate

Add the HasApiTokens trait to your User model:

use Laravel\Sanctum\HasApiTokens;

class User extends Authenticatable
{
    use HasApiTokens, Notifiable;
   
    // ...
}


Register the Sanctum middleware in your Kernel class:


protected $middlewareGroups = [
    // ...
    'api' => [
        EnsureFrontendRequestsAreStateful::class,
        'throttle:60,1',
        \Illuminate\Routing\Middleware\SubstituteBindings::class,
        \Laravel\Sanctum\Http\Middleware\EnsureFrontendRequestsAreAuthorized::class,
    ],
];


Generate a new API token for your authenticated user:


$token = $user->createToken('API Token')->plainTextToken;

Use the generated API token to authenticate your API requests:


Authorization: Bearer {api_token}

You can now create your API routes and controllers as usual. To protect a route with Sanctum, you can use the auth:sanctum middleware:


Route::middleware('auth:sanctum')->get('/user', function (Request $request) {
    return $request->user();
});


CRUD EXAMPLE

Next, let's create a Product model and migration file to store our product data. Run the following commands to create them:


php artisan make:model Product -m

This will create a Product.php model file and a migration file for the products table.

In the migration file, add the following code to define the columns for the products table:

public function up()
{
    Schema::create('products', function (Blueprint $table) {
        $table->id();
        $table->string('name');
        $table->text('description');
        $table->decimal('price', 8, 2);
        $table->timestamps();
    });
}

Next, run the migration to create the products table:


php artisan migrate


Now, let's create a ProductController to handle the CRUD operations. Run the following command to generate a new controller:

php artisan make:controller ProductController --api

This will create a new ProductController.php file in the app/Http/Controllers folder with boilerplate code for a RESTful API.

Add the following code to the ProductController to define the CRUD methods:

use App\Models\Product;
use Illuminate\Http\Request;

class ProductController extends Controller
{
    public function index()
    {
        $products = Product::all();
        return response()->json($products);
    }

    public function store(Request $request)
    {
        $product = Product::create($request->all());
        return response()->json($product);
    }

    public function show(Product $product)
    {
        return response()->json($product);
    }

    public function update(Request $request, Product $product)
    {
        $product->update($request->all());
        return response()->json($product);
    }

    public function destroy(Product $product)
    {
        $product->delete();
        return response()->json(null, 204);
    }
}


Next, let's protect our API routes with Sanctum. In the routes/api.php file, add the following code to define the routes and apply the auth:sanctum middleware:

use App\Http\Controllers\ProductController;
use Illuminate\Support\Facades\Route;

Route::middleware('auth:sanctum')->group(function () {
    Route::apiResource('products', ProductController::class);
});

Now, to test our API, we can use tools like curl or Postman to send HTTP requests to the API endpoints.


For example, to create a new product, we can send a POST request to http://localhost:8000/api/products with a JSON payload:

{
    "name": "Product A",
    "description": "This is product A",
    "price": 19.99
}

To retrieve all products, we can send a GET request to http://localhost:8000/api/products.

To update a product, we can send a PUT request to http://localhost:8000/api/products/{product_id} with a JSON payload:

{
    "name": "Product A (updated)",
    "description": "This is product A (updated)",
    "price": 29.99
}


To delete a product, we can send a DELETE request to http://localhost:8000/api/products/{product_id}.


I hope this helps you get started with creating a Laravel API with Sanctum.




laravel add new column in existing table

In Laravel, you can add a new column to an existing table using migrations. Here are the steps:

  1. Open your terminal or command prompt and navigate to your Laravel project directory.

  2. Run the following command to create a new migration file


php artisan make:migration add_column_to_table --table=your_table_name

  1. Replace "add_column_to_table" with a name that describes the purpose of your migration, and "your_table_name" with the name of the table you want to add a column to.

  2. After running the command, Laravel will generate a new migration file in the "database/migrations" directory with the current timestamp and the name you specified.

  3. Open the migration file in your text editor and add the new column using the "addColumn" method on the Schema facade. For example, if you want to add a "phone_number" column to a "users" table, you could add the following code:


use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class AddColumnToTable extends Migration
{
    public function up()
    {
        Schema::table('users', function (Blueprint $table) {
            $table->string('phone_number');
        });
    }

    public function down()
    {
        Schema::table('users', function (Blueprint $table) {
            $table->dropColumn('phone_number');
        });
    }
}


  1. In this example, the "up" method adds a new "phone_number" column to the "users" table, and the "down" method removes it if the migration is rolled back.

  2. Save the migration file and return to your terminal or command prompt.

  3. Run the following command to run the migration and add the new column to your database:


php artisan migrate


This will execute all pending migrations, including the one you just created.

That's it! You have successfully added a new column to an existing table in your Laravel project.




Laravel mPdf add custom font

  1. Download the font you want to use and save it in your Laravel project's "public/fonts" directory.

  2. Open your controller or create a new one and import the mPDF class at the top of your file:


use Mpdf\Mpdf;

Create a new instance of the mPDF class:


$pdf = new Mpdf();

Use the "AddFont" method to add the font to mPDF. You'll need to provide the path to the font file, the font name, and any additional options you want to set. Here's an example


$font_path = public_path('fonts/YourFontName.ttf');

$pdf->AddFont('YourFontName', '', $font_path);



Replace "YourFontName" with the actual name of the font file (without the ".ttf" extension).

You can also set additional options such as the font weight and style



$pdf->AddFont('YourFontName', 'B', $font_path, 32);


  1. In this example, the font weight is set to "B" (bold) and the font size is set to 32.

  2. Use the "SetFont" method to set the font you just added as the default font:



$pdf->SetFont('YourFontName', '', 12);


  1. In this example, the font size is set to 12.

  2. Add content to your PDF as usual using the mPDF class.

  3. Generate the PDF and return it as a download or stream:


$pdf->Output('YourFileName.pdf', 'D');


  1. Replace "YourFileName.pdf" with the name you want to give your PDF file, and "D" to download the file.

That's it! You have successfully added a custom font to mPDF in your Laravel project.



laravel how to create controller with resource

In Laravel, you can create a controller with resource using the artisan command. Here are the steps:

  1. Open your terminal or command prompt and navigate to your Laravel project directory.

  2. Run the following command to create a new controller with resource:


php artisan make:controller YourControllerName --resource


  1. Replace "YourControllerName" with the name you want to give your new controller. The "--resource" flag tells Laravel to create a controller with the CRUD operations for a resource.

  2. After running the command, Laravel will generate a new controller in the "app/Http/Controllers" directory with the name you specified. It will include methods for the following CRUD operations:

    • index: Display a listing of the resource.
    • create: Show the form for creating a new resource.
    • store: Store a newly created resource in storage.
    • show: Display the specified resource.
    • edit: Show the form for editing the specified resource.
    • update: Update the specified resource in storage.
    • destroy: Remove the specified resource from storage.

    You can modify these methods to suit your needs.



That's it! You now have a new controller with resource in your Laravel project.
