laravel validation, how to add validation rule on client side?

//html code
<form>
<input type="radio" id="defult" name="price_type" value="default">
<label for="defult">Default Price</label><br>
<input type="radio" id="custom" name="price_type" value="custom">
<label for="custom">Custom Price</label><be>

<input placeholder="Custom Price" class="form-control" name="custom_price">
</form>

$('input[type=radio][name=price_type]').change(function() {
    if (this.value == 'default') {
        //make custom_price optional
    }
    else if (this.value == 'custom') {
        //make custom_price required
    }

});

Actually, I have a radio box for the custom price or default price, if the user selects the custom price then want to make input[name=custom_price] required or if the user selects default price then make input[name=custom_price] optional.

Laravel \Illuminate\Filesystem\Filesystem File:files() count only the files that have specific extension e.g jpg png in all subfolders

i can count files in the folder with this :

 \Illuminate\Filesystem\Filesystem\File::files($path)

then i can count all files in all subfolders (with specific storage)

 foreach ($directories as $directory) {

     $path = Storage::disk($this->disk)->path($directory);

     $files = \Illuminate\Filesystem\Filesystem\File::files($path);
            if ($files) {
                $count += count($files);
            }
     }
}

i can count all files in this folder

How can i count only png or jpeg files with minimum overload?

thanks in advanced!

Search in the related model in Laravel

I have post table like this :

id | post_title | category_id

and this is category table

id | category_title

this is the relation between these two which is inside post model :

  public function category()
    {
        return $this->belongsTo(Category::class, 'category_id', 'id');
    }

I want to get the record of post table where category_title or post_title matches the keyword entered by user.

I'm retrieving data something like:

Post::where(['title'=>$request->title])->with('category')->paginate(10);

but here it is only fetching Post title but i also want it to search it in category title.

Any help is highly appreciated.

How to add watermark to image on upload in laravel 5.8

I want to add watermark when a user uploads an image on the system. My current code works fine but I need it to work on upload. What do I add to my code?

My WatermarkController file

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Image;

class WaterMarkController extends Controller
{
  public function imageWatermark()
  {
 $img = Image::make(public_path('images/background.png'));

 /* insert watermark at bottom-right corner with 10px offset */
 $img->insert(public_path('images/watermark.png'), 'bottom-right', 10, 10);

 $img->save(public_path('images/background.png'));

 $img->encode('png');
 $type = 'png';
 $new_image = 'data:image/' . $type . ';base64,' . base64_encode($img);

 return view('show_watermark', compact('new_image'));
 }

 public function textWatermark()
 {
 $img = Image::make(public_path('images/background.jpg'));

 $img->text('MyNotePaper', 710, 370, function ($font) {
     $font->file(public_path('font/amandasignature.ttf'));
     $font->size(30);
     $font->color('#f4d442');
     $font->align('center');
     $font->valign('top');
     $font->angle(0);
 });

 $img->save(public_path('images/new-image.png'));

 $img->encode('png');
 $type = 'png';
 $new_image = 'data:image/' . $type . ';base64,' . base64_encode($img);

 return view('show_watermark', compact('new_image'));
 }

 }

web.php file

Route::get('watermark-image', 'WaterMarkController@imageWatermark');
Route::get('watermark-text', 'WaterMarkController@textWatermark');

Like I said my current code works fine but I need it to work dynamically when a user uploads an image to the system, with this code you would have to configure the watermark.png and the backgroud.jpg to the same directory then access the route watermark-image. please help me on this I am very new to Laravel. Thanks
