How to Upload files with Cloud Storage on Web - Firebase #19

In this chapter, we will learn how to upload an image to the Firebase Storage from the Laravel PHP project using the kreait/laravel-firebase package.

First of all you have to visit the Storage tab in the Firebase. And click on the "Get Started".

Then on click of get started, you will find two options to setup the rules and the location. For now keep the rules as it is. By default, rules would be allowed all reads and writes from authenticated users. You can learn more for making it more secure, but its not generally required.

Now the free Blaze plan does not allow the location change. It will default to us-central.

After successful setup, you would land to the root folder. This is similar to any folder structure. You can create any n level folders.

We have created the Student folder and will upload student images with Firebase doc id of Student collection document id

Following is the code to upload image to Firebase. Here we first make for image of Formdata. We would temporary upload to local public folder of your laravel project and after uploading to firebase we delete that image

 $image = $request->file('image'); //image file from frontend  
 $student   = app('firebase.firestore')->database()->collection('Student')->document('defT5uT7SDu9K5RFtIdl');  
 $firebase_storage_path = 'Students/';  
 $name     = $student->id();  
 $localfolder = public_path('firebase-temp-uploads') .'/';  
 $extension = $image->getClientOriginalExtension();  
 $file      = $name. '.' . $extension;  
 if ($image->move($localfolder, $file)) {  
     $uploadedfile = fopen($localfolder.$file, 'r');  
     app('firebase.storage')->getBucket()->upload($uploadedfile, ['name' => $firebase_storage_path . $name]);  
     //will remove from local laravel folder  
     unlink($localfolder . $file);  
     echo 'success';  
 } else {  
     echo 'error';  
 }  

Done your image gets upload

Now below code is those who use base64 string image instead of formdata image.

 $image = $request->image; //base64 string from frontend  
 $student   = app('firebase.firestore')->database()->collection('Student')->document('defT5uT7SDu9K5RFtIdl');  
 $firebase_storage_path = 'Students/';  
 $name     = $student->id();  
 $localfolder = public_path('firebase-temp-uploads') .'/';  
 if (!file_exists($localfolder)) {  
     mkdir($localfolder, 0777, true);  
 }  
 $parts = explode(";base64,", $image);  
 $type_aux = explode("image/", $parts[0]);  
 $type = $aux[1];  
 $base64 = base64_decode($parts[1]);  
 $file = $name . '.png';  
 if (file_put_contents($localfolder . $file, $base64)) {  
     $uploadedfile = fopen($localfolder . $file, 'r');  
     app('firebase.storage')->getBucket()->upload($uploadedfile, ['name' => $firebase_storage_path . $name]);  
     //will remove from local laravel folder  
     unlink($localfolder . $file);  
     echo 'success';  
 } else {  
     echo 'error';  
 }
