how to save base64 image decode to public folder in laravel

Question

I get an image with format String base64 and i want to decode that string to be an image and save it to public folder in laravel.

This is my controller:

//decode string base64 image to image 
$image = base64_decode($request->input('ttd'));
//create image name
$photo_name = time().'.png';
$destinationPath = public_path('/uploads');
//save image to folder
$image->move($destinationPath, $photo_name);
$img_url = asset('/uploads'.$photo_name);


$data = new Transaction();
$data->transaction_id = $request->input('fa_transaction_id');
$data->user_id = $request->input('userid');
$data->photo_name = $photo_name;
$data->photo_url = $img_url;
$data->save();

when i'm trying echo $image, i got the decode value, and also for $photo_name i got the value too, but when the function running i got this error

Call to a member function move() on string

how to fix this error?

Answer 1

//Controller

use Illuminate\Support\Facades\Storage;

//Inside method

    $image = $request->image;  // your base64 encoded
    $image = str_replace('data:image/png;base64,', '', $image);
    $image = str_replace(' ', '+', $image);
    $imageName = str_random(10) . '.png';

    Storage::disk('local')->put($imageName, base64_decode($image));

Also, make sure that your local disk is configured like that in /config/filesystems.php

    'local' => [
        'driver' => 'local',
        'root' => storage_path('app/public'),
    ]

With that, file will be saved in /storage/app/public directory.

Don't forget to write php artisan storage:link to make files from that directory available in /public directory, so users will can retrieve them.

Saving image in database not a recommanded way to store image in db, reason is speed increase of memory, The correct way is just save the link to it.
Anyway, you can save your image in base64 with these line of code.
Get the correct image from path in your server not from link in the $path.

<?php
    // Base 64 transform image
    $path = __DIR__ .'/myfolder/myimage.png';
    $type = pathinfo($path, PATHINFO_EXTENSION);
    $data = file_get_contents($path);
    $base64 = 'data:image/' . $type . ';base64,' . base64_encode($data);
    echo $base64;
