In app/config/routing.yml add the following:

    prefix: imagetag/

In your HTML file, add those lines:

<!-- Jquery and CSS in the header part of your HTML -->
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.3/jquery-ui.min.js"></script>

Simple usage

Adding tags

Note: 'theScope' must be different for every image you want to display on a same document. It's an HTML Id.

{{ setImageTag (
    'image/IMG001.jpg',
    'theScope',
    'optional - Image Alt property'
) }}

Explanation :

• The first parameter is the path of the picture, it is possible to use any twig function returning a path as GregwarImageBundle functions.
• The second parameter will be used as Scope to allow the js script distinguishes different images.
• Tags associated with images considering the file name, the width and height of the image.
• Creating tags is secure according to the following role : IS_AUTHENTICATED_FULLY, you can change it by extending the bundle controller.

Display tags

{{ imageTag (
    'image/IMG001.jpg',
    'theScope',
    'optional - Image Alt property'
) }}

Usage with custom controller

It is possible to use a controller with twig custom functions to modify the way the script will save the tags.

Adding tags - custom controller

{{ setImageTag (
    entity.filePath,
    'theScope',
    'Not optional - Image Alt property',
    path('MyCustomControllerRoute', {'id':entity.id, 'fieldName':'file', 'otherUsefulParameters':parameters})
) }}

Explanation :

• MyCustomControllerRoute is the route used by the Ajax request
• You must definitely specify a parameter in your way, even if it is a decoy to initiate the "query string"

• The query string added to your Route by the script js is as follows :

• init is equal to true on the first query, used for initialization purpose
• htmlcontent contains tags to save

Display tags - custom controller

{{ imageTag (
    entity.filePath,
    'theScope',
    'Not optional - Image Alt property',
    path('MyCustomControllerRoute', {'id':entity.id, 'fieldName':'file', 'otherUsefulParameters':parameters})
) }}

Other

Displaying tags

If you only need to display the tags you're free to only include imagetag-display.js.

In that file I also include the showTags({{theScope}}) and hideTags({{theScope}}) js function that will help you to hide and display all tags at once.
