Offcanvas Section

You can publish whatever you want in the Offcanvas Section. It can be any module or particle.

By default, the available module positions are offcanvas-a and offcanvas-b but you can add as many module positions as you want from the Layout Manager.

You can also add the hidden-phone module class suffix to your modules so they do not appear in the Offcanvas Section when the site is loaded on a mobile device.

Compatibility with CS-Cart & Multi-Vendor

Versions

This is how you specify the compatibility of your add-on with specific versions of CS-Cart/Multi-Vendor:

<compatibility>
    <core_version>
        <min>4.3.2</min>
        <max>4.3.6</max>
    </core_version>
</compatibility>

You don’t have to specify both <min> and <max>. They stand for the earliest and the latest supported versions respectively.

If you try to install this add-on on version 4.3.7, you’ll get the following error:

Error: Version of your cart (4.3.7) is not supported. Minimal: 4.3.2. Maximal: 4.3.6.

Products (CS-Cart or Multi-Vendor)

There are two products: CS-Cart (referred to as ULTIMATE) and Multi-Vendor (referred to as MULTIVENDOR). You can mark your add-on as compatible with either of them, or with both.

  • One product:

    <compatibility>
        <core_edition>MULTIVENDOR</core_edition>
    </compatibility>
    
  • Multiple products:

    <compatibility>
        <core_edition>MULTIVENDOR,ULTIMATE</core_edition>
    </compatibility>
    

If you specify MULTIVENDOR in addon.xml and try to install the add-on on CS-Cart, you’ll see the following error:

Error: Edition of your cart (ULTIMATE) is not supported. Required: MULTIVENDOR.

Compatibility with Server Environment

PHP Versions

You can specify the minimum and maximum supported PHP version:

<compatibility>
    <php_version>
        <min>5.6.6</min>
        <max>7.1.1</max>
    </php_version>
</compatibility>

You don’t have to specify both <min> and <max>. They stand for the earliest and the latest supported PHP versions respectively.

If you try to install this add-on on a server with version 5.5.9, you’ll get the following error:

Error: PHP version (5.5.9-1ubuntu4.14) is not supported. Minimal: 5.6.1. Maximal: 7.1.1.

PHP Extensions

You can specify the required and conflicting PHP extensions for your add-on.

  • Required extension:

    <compatibility>
        <php_extensions>
            <gd>
                <supported>Y</supported>
            </gd>
        </php_extensions>
    </compatibility>
    

    If the required PHP extension (in our case it’s gd) is not installed, you’ll see an error:

    Error: The gd extension should be installed on your server for correct add-on operation.

  • Specific version of a required extension:

    <compatibility>
        <php_extensions>
            <json>
                <min>3.0</min>
                <max>4.0</max>
            </json>
        </php_extensions>
    </compatibility>
    

    In this case you don’t have to add <supported>Y</supported>.

    If the PHP extension version is different from the required versions, you’ll see an error:

    Error: The json version (1.3.2) is not supported by the add-on. Minimal: 3.0. Maximal: 4.0.

  • Conflicting extension:

    <compatibility>
        <php_extensions>
            <gd>
                <supported>N</supported>
            </gd>
        </php_extensions>
    </compatibility>
    

    If the conflicting PHP extension (in our case it’s gd) is installed, you’ll see an error:

    Error: The gd extension should be removed from your server for correct add-on operation.
