Uploading images or files in Laravel

We are going to learn how to load images in Laravel; for that, we are going to assume that you already have some form ready in Laravel.

In this case, we are going to work with uploading images to a post, which has the following structure, its model:

class Post extends Model
{
    protected $fillable = ['title', 'slug', 'content', 'category_id', 'description', 'posted', 'image'];

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

The form view looks like the following:

The important thing to note here is the multipart form data field to enable file upload, and the file.

To process the form, we have the following:

<form action="{{ route('post.update',$post->id) }}" method="post" enctype="multipart/form-data">
        @method("PATCH")
 @csrf

<label for="">Título</label>
<input type="text" class="form-control" name="title" value="{{ old('title', $post->title) }}">

<label for="">Slug</label>
<input type="text" class="form-control" name="slug" value="{{ old('slug', $post->slug) }}">

<label for="">Categoría</label>
<select class="form-control" name="category_id">
    <option value=""></option>
    @foreach ($categories as $title => $id)
        <option {{ old('category_id', "$post->category_id") == $id ? 'selected' : '' }} value="{{ $id }}">
            {{ $title }}</option>
    @endforeach
</select>

<label for="">Posteado</label>
<select class="form-control" name="posted">
    <option {{ old('posted', $post->posted) == 'not' ? 'selected' : '' }} value="not">No</option>
    <option {{ old('posted', $post->posted) == 'yes' ? 'selected' : '' }} value="yes">Si</option>
</select>

<label for="">Contenido</label>
<textarea class="form-control" name="content"> {{ old('content', $post->content) }}</textarea>

<label for="">Descripción</label>
<textarea class="form-control" name="description">{{ old('description', $post->description) }}</textarea>


<label for="">Imagen</label>
<input type="file" name="image">

<button type="submit" class="btn btn-success mt-3">Enviar</button>
       
</form>

And the function to process the form:

public function update(PutRequest $request, Post $post)
    {
       // Resto de la funcion de carga 
        $data = $request->validated();
        if( isset($data["image"])){
            $data["image"] = $filename = time().".".$data["image"]->extension();
            $request->image->move(public_path("image/otro"), $filename);
        }
        $post->update($data);
}

It is very simple; remember that uploading files in Laravel is disk-based, a disk is anything that can store files, as in this case it would be a local folder to the project, but it could be another service like Amazon Web Server; you can verify this in the config/filesystem.php file.

For the rest, since we have the image as an optional payload, we ask if it is defined; we generate the name of the image with the time() function and save it to a "disk", which is our local folder.

And that's it, with this, we can load our files in Laravel.

Remember that this post is part of my course and book on Laravel.
