Download the PHP package sergmoro1/yii2-uploader without Composer

Yii2 module for image|file upload

Multiple uploading, sorting file collection by mouse, adding description for the file, cropping. Resize images using the queue component.

Demo

Photos by categories, photo gallery BEFORE | AFTER.

Advantages

A common approach for working with uploading images or files in an application.

If the model needs images or files, it is enough:

• to connect the behavior,
• define the subdirectory in which they will be stored,
• define the desired image sizes

For example common\models\User.php

Directories

Information about all uploaded files are stored in one table onefile. There is no need to define a field of type file in the model, which need files.

The files are uploaded and stored in the directory defined as a concatenation of paths of three aliases @absolute, @host and @uploader. All aleases should be defined in appropriate config file. For example in common/config/main-local.php if storage folder are the same for backend and fronend.

But there may be different configurations.

If both the backend and frontend are on the same host, the @host alias can be leaved empty. The same case for basic Yii template.

In the folder the files are arranged by users and sizes.

• /uploads/user/2
• /uploads/user/2/thumb
• /uploads/user/2/original

Where 2 is the user ID or subdir. subdir can be blank, then all files will be saved in one folder. subdir can be defined when widget placed in a view.

Sizes in an example are thumb, main, original. More sizes can be defined but those are must have.

Installation

The preferred way to install this extension is through composer.

Either run

composer require --prefer-dist sergmoro1/yii2-uploader

or add

"sergmoro1/yii2-uploader": "^2.0.0"

to the require section of your composer.json.

Run migration.

php yii migrate --migrationPath=@vendor/sergmoro1/yii2-uploader/src/migrations

If you used a previous version sergmoro1\yii2-byone-uploader then run only the next migration.

php yii migrate --migrationPath=@vendor/sergmoro1/yii2-uploader/src/migrations/v1

Configuration

To register the module in an app common/config/main.php (advanced) or in appropriate config file.

For file storage configuration in common/config/main-local.php or any other config file add lines appropriate for your app.

If queue should be using for image resizing, then queue component must be defined. The name of the queue component must be exactly queue.

Usage

To do uploading place the widget in a _form.php or any other view.

If image should be cropped, subdirectories original, main, thumb must to be defined.

May be uploaded any amount of files for one model but files amount can be limited by limit parameter of the widget.

If subdir will be defined as an empty string then all files will be uploaded in the same folder but with subfolders that was defined in sizes.

Description of uploaded files

You can leave descriptions to the files. To do this in the _form.php, in the already mentioned widget, you need to add the parameter appendeixView.

And add to the view/views/user/appendix.php the following content:

Field description defined by default, but fields not limited.
