FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

to the require section of your composer.json file.

Configuration

Once the extension is installed, configure it in config\main.php setting imageBaseUrl, fileUploadBasePath and fileUploadBaseUrl :

1) Add fileUploader module to config.php

2) Add the module in bootstrap section of config\main.php

3) Apply database migration

Changes to Model, View and Controller

I suggest to create ModelForm class that extends Model class and add an attribute to handle files (in this case, 'photo')

If you need to update other fields on database, sync() method has a last parameter $options that has this structure:

filter->andWhere data contains other field to match the record, saveFields contains set of key=>value fields to insert/update.

Changes to Model

It can be used rules validation base on file, such as:

Changes to View

Add an formSessionId hidden input field to manage (eventually!) multiple browser tabs opened in same web page (with form upload). Then can insert your own file input widget or use that provided by the extension, derived from KartikFileInput

This widget is automatically configure to get validation rules from Model.

Changes to Controller

Create and Update actions content is the same of standard.

Tabular form

In case of tabular form (multiple instances of same Model inside the same form), only the action inside the controller has to be modified. Here an example:

Changes to Controller

Models from multiple files

When you need to store multiple models from multiple files, this is the right approach:

Changes to Model Inside the model, in load() you will pass an extra parameter to identify which $_FILES index to use

Changes to Controller In Controller, you will add fileInputIndexName to pass index of $_FILES where get file data
