Multipass - PHP SDK

Requirements

This SDK has been tested with PHP 5.5 and greater.

We are unable to provide official support for earlier versions. For more information about end of life PHP branches, see this page.

Install

This package is intended for custom PHP websites and advanced integrations.

If you're using WordPress, we've made it easy for you. Download the SQweb plugin directly from WordPress.org, or check out the source.

Recommended : Composer + dotenv

1. In your project root, execute composer require mltpss/php-sdk.

2. Create a .env file at the root of your project, or edit it if you already have one.

3. In .env, paste the following configuration:

   Change SQW_ID_SITE with your website ID and SQW_SITENAME with the name to show on the large Multipass button.

For additional settings, see "Options" below.

Composer + Manual Configuration

1. In your project root, execute composer require mltpss/php-sdk.
2. Create a new SQweb object passing in its configuration through the constructor. SQW_ID_SITE and SQW_SITENAME must be specified.

For additional settings, see "Options" below.

Manually

1. Download the latest release of the SDK and unzip it in a folder named sqweb in your project root.

2. Create a file named sqweb.config at the root of your project. This file should be one level up from the sqweb folder you just created, i.e. :

3. In sqweb.config, paste the following configuration:

   Change SQW_ID_SITE with your website ID and SQW_SITENAME with the name to show on the large Multipass button.

For additional settings, see "Options" below.

Usage

1. Initializing the SDK

First, you have to initialise SQweb variable on the pages where you wish to use it.

If you used composer:

If you installed manually:

2. Tagging your pages

Then, you need to add our JavaScript tag to your pages. This function will do it for you, and should be inserted before the closing </body> tag in your HTML.

Make sure it is present on all your pages. Most likely you'll just have to add it to your template.

If you previously had a SQweb JavaScript tag, make sure to remove it to avoid any conflicts.

3.a Checking the credits of your subscribers

Check if the user has credits, so that you can disable ads and/or unlock premium content.

3.b Retrieving the user's email

If he wants it, the user can share his email with you, to retrieve it, check if the cookie named mltpss_e exists. Inside will be a base64 encoded string you need to retrieve and decode on your side.

for instance:

This piece of code will store the email in the $email variable if the cookie is set.

4.a Showing the Multipass button

Use this code to display the Multipass button on your pages:

We have 3 additionals sizes for the button, to use it, pass a string to the function:

We also have another type of button, the free button, which offer to share the user's email with you. To display it, use this function:

4.b Customizing the Multipass button

If you want to customize our different type of button, put the following in your config file (.env if you used composer and dotenv or sqweb.config if you did not) of in the sqweb config file. For instance: SQW_LOGIN=Hello world Will show Hello world instead of Premium with Multipass on the regular button for logged out visitors.

5. More functions

Display a support div for your users

php $sqweb = new SQweb;

$sqweb->supportBlock();

We recommend that you use it with our other blocking function :

Display only a part of your content to non premium users

For instance:

Free users will see:

Display your content later for non paying users

Example:

Limit the number of articles free users can read per day

For instance, if I want to display only 5 articles to free users:

Options

Unless otherwise noted, these options default to false. You can set them in your configuration.

Known Issues

If you change the value of SQW_DWIDE after initial deployment, your users will have to log in again since their auth cookie will no longer be valid.

Troubleshooting

I am not seeing the Multipass button

Please make sure you have properly tagged your pages. Mind the position of the include and tag.

I can see the Multipass button, but I cannot login

The authentication requires cookies, which require fully qualified domain names. If you are testing on localhost or an IP, the authentication will succeed but won't be able to save a cookie in your browser.
