If you keep getting 403 forbidden error on your Laravel storage files and you want to know how to fix this, you have landed on the right site.
403 forbidden error is typically when you do not have enough permission to read a file and it happens mostly on live servers (on production).
I was working on a Laravel project that allows users to upload and share files. To manage all user’s files, I am creating a sub-folder for each user with his ID. For example, if the user ID is 2, a folder named “2” will be created inside the storage sub-folder “files”. So the complete path to that folder will be: “storage/app/public/files/2”. I got this error due to permission of sub-folder “2”. I managed to fix it after a few hours, so I thought I might share the solution with others and it might help someone.
If you are seeing this error on your localhost, try running the following command:
phpartisanstorage:link
The solution that works for me is to set the permission of the parent folder as soon as the file is uploaded.
$file_path ="folder_name/". $file->getClientOriginalName(); // storage/app/public/folder_name/file.png$file->storeAs("/public", $file_path);// Get the full path to the folder$full_path =storage_path('app/public/folder_name');// Set permissions using PHP's chmod functionchmod($full_path, 0775);
This will ensure to give the read, write, and execute permission to the folder, not the files inside it. If you give the execute permission to the file, then a hacker can put a malicious file in it and execute it.
You might need to delete the folder “folder_name” and try again, it should work fine now. So that’s how you can fix the 403 forbidden error on your Laravel storage files. If you face any problem in following this, kindly do let me know.
Previously, we created a tutorial to show you how you can download an image in your storage using Java. In this tutorial, we will show you how you can download any file in your android phone’s storage using Kotlin. First, you need to create a file named “DownloadImageTask.kt” and write the following code in it:
class DownloadImageTask(
var imagePath: String?,
var fileName: String?
) : AsyncTask<Void, Void, Void>() {
var cachePath: String = ""
override fun doInBackground(vararg voids: Void?): Void? {
try {
val root =
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOCUMENTS)
val directoryPath = File(root.absolutePath + "/")
if (!directoryPath.exists()) {
directoryPath.mkdir()
}
val cachePath = File("$directoryPath/$fileName")
cachePath.createNewFile()
val buffer = ByteArray(1024)
var bufferLength: Int
val url = URL(imagePath)
val urlConnection = url.openConnection() as HttpURLConnection
urlConnection.requestMethod = "GET"
urlConnection.doOutput = false
urlConnection.connect()
val inputStream = urlConnection.inputStream
val fileOutput = FileOutputStream(cachePath)
while (inputStream.read(buffer).also { bufferLength = it } > 0) {
fileOutput.write(buffer, 0, bufferLength)
}
fileOutput.write(buffer)
fileOutput.close()
inputStream.close()
this.cachePath = cachePath.toString()
} catch (e: FileNotFoundException) {
e.printStackTrace()
} catch (e: ProtocolException) {
e.printStackTrace()
} catch (e: IOException) {
e.printStackTrace()
}
return null
}
override fun onPostExecute(aVoid: Void?) {
// when the operation is done
// you can use this.cachePath here
}
}
Now, whenever you want to download any file, you just need to run the following line passing the file’s absolute path in the first parameter. And the file name as the second parameter. The second parameter file name will be the name that will be saved in your phone’s storage.
That’s how you can download any HTTP file in your android phone’s storage using Kotlin. If you face any problem in following this, kindly do let me know in the comments section below.
In this tutorial, we are going to show you, how you can copy or move a folder from one storage to another storage folder in Laravel.
Video tutorial
So let’s say in your storage/app/public folder, these folders are already created by Laravel by default. We created 2 folders named folder1 and folder2. In folder1, we have a folder named files and it has some files. Now you want to move the entire files folder with all his files in folder2.
storage/app/public
folder1
files
folder2
Copy folder from one storage to another – Laravel
Following will be the code that will copy the entire folder from one storage to another:
// include classes
use Storage;
use Str;
// get all files from source folder
$files = Storage::files("public/folder1/files");
// loop through each file
foreach ($files as $file)
{
// to get the content the file, we need to get it from public/storage
// so change the path to public/storage folder
$file = Str::of($file)->replace("public/folder1/", "public/storage/folder1/");
// get the content of file
$file_content = file_get_contents($file);
// extract the file name from path
$file_name_parts = explode("/", $file);
if (count($file_name_parts) > 0)
{
// name is at the last index of array
$file_name = $file_name_parts[count($file_name_parts) - 1];
// set destination path
$file_path = "public/folder2/files/" . $file_name;
// save the file in destination folder
Storage::put($file_path, $file_content);
}
}
// delete the source folder
// do this only if you want to move the folder
Storage::deleteDirectory("public/folder1/files");
Explanation
First, we are going to get all the files from the source folder.
Then we will loop through each file.
Then we need to get the content of each file. But in order to get the content of the Laravel storage file, we need to access it from a public shortcut path.
So to change the path, we are going to use another class named Str.
Then we need to call the function of and tell the target string and call the replace function. We will replace the “public/folder1/” (notice slash at the end) with the “public/storage/folder1/”. And save it back in the $file variable.
Now we can get the content of the file by calling the PHP native function file_get_contents and pass the path of the file, and save it in the variable $file_content. If you get any error here, you need to run the following command at the root of your project:
php artisan storage:link
Then we need to extract the file name from the file path. First, we will split the file path by slash using PHP explode function. It will return an array and we need to get the last index of this array. So we will check if the array is not empty. Then we will get the last index of the array. So if the length of the array is 5, minus 1 becomes 4, so it will fetch the element at index 4 which is the name of the file.
After that, we are setting the destination path. It will be in the public/folder2/files and the name of the file. Right now, folder2 does not have a files folder, but it will automatically create one. To save the file, we need to call the Storage::put method. Pass the destination path and the content of the file.
In order to have the move functionality, you simply need to remove the source folder after it has been copied. So after the foreach loop, we will call the deleteDirectory method from the Storage class and pass the path of the source folder.
If you run the code now, you will see that folder1 becomes empty but now folder2 has all the files.
If you are working on AJAX and are getting any errors, feel free to check our tutorial on how to check Laravel errors from AJAX requests.
So that’s how you can copy or move an entire folder from one storage to another in Laravel. If you face any problems in following this, kindly do let me know.
In this tutorial, we are going to teach you, how you can upload, download and delete files from Firebase Storage. Firebase Storage is a service provided by Google that allows you to save files on their server. The free plan allows you to upload data up to 1 GB. More data can be bought from the Firebase Pricing page.
What you are going to learn:
Upload files on Firebase Storage.
Save the data in Realtime Database.
Fetch files from the Firebase Storage.
Download files from Firebase Storage.
Fix CORS issue if working in localhost.
Install gsutil.
Delete files from Firebase Storage.
Video tutorial:
Upload file
We are going to upload the file to the Firebase storage and save its path in Firebase Realtime Database. It is another service provided by Google to save data in JSON format. To upload the file, we are going to show a form with an input type file that allows the user to select any type of file. We will be using Vue JS to render the HTML to view the data in real-time, for example, newly uploaded files will be displayed automatically and deleted files will be removed from the view without having to refresh the page.
This will display a form with an input type file to upload a file. And a submit button which when clicked will submit the form. Vue JS production file can be downloaded from here. Now you need to attach a submit event listener to this form using Javascript.
<script type="module">
// [initialize firebase here]
window.addEventListener("load", function () {
document.getElementById("upload-form").addEventListener("submit", function () {
event.preventDefault();
var form = event.target;
var file = form.file.files[0];
console.log(file);
// [upload in storage here]
});
});
</script>
If you select the file and hit submit, you will see your selected file object in the browser console. Now you need to do 2 things; initialize firebase, and upload the file. To initialize firebase, you need to create an app at Firebase Console.
Add new project.
Enter name of project.
When project is created, select “web”.
Copy the firebaseConfig variable.
Replace the [initialize firebase here] section with the following:
import { initializeApp } from "https://www.gstatic.com/firebasejs/9.1.0/firebase-app.js";
import { getStorage, ref as stRef, uploadBytes } from "https://www.gstatic.com/firebasejs/9.1.0/firebase-storage.js";
import { getDatabase, ref as dbRef, push, set } from "https://www.gstatic.com/firebasejs/9.1.0/firebase-database.js";
// Your web app's Firebase configuration
const firebaseConfig = {
apiKey: "",
authDomain: "",
projectId: "",
storageBucket: "",
messagingSenderId: "",
appId: ""
};
// Initialize Firebase
const app = initializeApp(firebaseConfig);
// Get a reference to the storage service, which is used to create references in your storage bucket
const storage = getStorage(app);
const database = getDatabase();
const databaseReference = dbRef(database, "files");
Replace the firebaseConfig variable with your firebase configurations. Now replace the [upload in storage here] section with the following:
This will upload the file in Firebase Storage in a folder named “files”. You can see it in your project’s dashboard in left menu in “Storage” page. Also, it will create a new element in “files” array in “Realtime Database” page.
Displaying Uploaded Files in Firebase Storage
Now the file is being uploaded in Firebase Storage and it’s path is also being saved in realtime database. Now you need to show all uploaded files. Replace the [show all uploaded here] section with the following:
This will create a simple HTML table. Now you need to do the following things:
Initialize Vue JS.
Get all data from realtime database.
Render in HTML table.
You can initialize the Vue JS from the following code:
var vueApp = new Vue({
el: "#app",
data: {
files: []
},
// [updated event goes here]
});
Then include “onValue” in your “firebase-database” import. So your firebase database import line will become:
import { getDatabase, ref as dbRef, push, set, onValue } from "https://www.gstatic.com/firebasejs/9.1.0/firebase-database.js";
Note the “onValue” in the import block. Similarly, add the “getDownloadURL” in the import of “firebase-storage”. So your firebase storage import line will become:
import { getStorage, ref as stRef, uploadBytes, getDownloadURL } from "https://www.gstatic.com/firebasejs/9.1.0/firebase-storage.js";
Note the “getDownloadURL” in the import block. Then write the following code in your Javascript:
function downloadFile() {
// prevent default href action
event.preventDefault();
// get URL from href
var anchor = event.target;
var url = anchor.getAttribute("href");
// get blob data
const xhr = new XMLHttpRequest();
xhr.responseType = "blob";
xhr.onload = function (event) {
const blob = xhr.response;
// get clickable URL of blob data
const blogUrl = window.URL.createObjectURL(blob);
// replace href with new blob value
anchor.setAttribute("href", blogUrl);
// remove the onclick listener
anchor.removeAttribute("onclick");
// download the file
anchor.click();
// free up the memory
window.URL.revokeObjectURL(blogUrl);
};
xhr.open("GET", url);
xhr.send();
}
// make the function global so it can be accessible from anchor tag onclick
window.downloadFile = downloadFile;
Run the code now, and you will be able to download the file.
Note: If you get a CORS error while working in localhost, then do the following steps:
Then add “deleteObject” in your import of “firebase-storage”. So your import line will look like this:
import { getStorage, ref as stRef, uploadBytes, getDownloadURL, deleteObject } from "https://www.gstatic.com/firebasejs/9.1.0/firebase-storage.js";
Then add the following event in your [updated event goes here] section:
updated: function () {
var forms = document.querySelectorAll(".delete-form");
for (var a = 0; a < forms.length; a++) {
forms[a].setAttribute("onsubmit", "onDeleteFormSubmit();");
}
}
This will attach an event listener to every delete form, which will be called when the form is submitted. Now you need to create the following function in your Javascript:
function onDeleteFormSubmit() {
event.preventDefault();
var form = event.target;
const tempDbRef = dbRef(database, "files/" + form.id.value);
set(tempDbRef, null);
const deleteStorageReference = stRef(storage, "files/" + form.name.value);
deleteObject(deleteStorageReference);
for (var a = 0; a < vueApp.files.length; a++) {
if (vueApp.files[a].id == form.id.value) {
vueApp.files.splice(a, 1);
break;
}
}
}
window.onDeleteFormSubmit = onDeleteFormSubmit;
This will first delete the data from the real-time database. Then it will delete the file from Firebase Storage. Finally, it will remove it from the Vue JS array, so it will automatically be removed from the HTML table too.
You can also create a realtime chat in Firebase. Learn how to do it from here.
Now you will be able to upload files to the Firebase Storage and save its path in Realtime Database. And also to download and delete the files from it. If you face any problems facing this tutorial, kindly let us know in the comments section below.
