Alternative text check for images
=================================

The Higher Education Package contains a check for missing alternative texts on images.
This feature is activated by default and can be deactivated in the extension settings.

If activated the check is processed every time when a relation to an image file is added
or changed in a content element. The image relation will be disabled (2) if there is no
alternative text and the user is informed by a flash message warning (1).

.. image:: ../../Images/AlternativeTextCheck/alternative-text-check.png
	:alt: Alternative text check
	:width: 762px

Disable check for single database fields
----------------------------------------
In some cases the check for an existing alternative text makes no sense, e.g. for images that
are used as background-images in the frontend. The check can be disabled for single database
fields. The following Typoscript setup is the default setting that comes with the Higher Education
Package. Extend the Typoscript with further table / field combinations to fit your needs. You can
add more than one field per table if needed.

.. code-block:: typoscript

	plugin.tx_highereducationpackage.alttext-check.ignore {
	    pages {
	        1 = menu_image
	    }
	    tx_highereducationpackage_domain_model_person {
	        1 = image
	        2 = images
	    }
	}

We also can ignore the check for tt_content fields base on CType here:

.. code-block:: typoscript

    plugin.tx_highereducationpackage.alttext-check.cTypeIgnore {
        uploads {
            1 = media
        }
    }
