How to Update an Image in Summernote with Laravel 7: A Comprehensive Guide

When working with file uploads in a web application built using Laravel 7, developers often encounter various challenges, especially when migrating from a local development environment to shared hosting. One common issue arises when updating images through the Summernote editor. Users may find that while everything works seamlessly on their local machines, error messages crop up when attempting the same on hosted servers. In this post, we will address this specific issue and provide a detailed solution to ensure smooth image updates regardless of the environment.

The Problem: Image Upload Failure on Shared Hosting

One user encountered the following error message when trying to update images in their application on shared hosting:

What's Happening?

The crux of the problem is that the file_put_contents() function fails if you attempt to write a file to a directory that does not exist. In the local development environment, the required directory /public/storage/article_image/ is present. However, on shared hosting, this directory may not exist, leading to the error.

The Solution: Ensure the Directory Exists

To address this issue, we need to modify the code to check if the target directory exists before trying to write an image file. If it doesn't exist, we should create it. Let's break this down step-by-step.

Step 1: Prepare for Image Upload

First, retrieve the image data from the Summernote editor and prepare the necessary variables:
