Tag Suggestion for symfony

I just have created a patch for sfFormExtraPlugin. It provides a new form widget called sfWidgetFormJqueryTagSuggestion designed to suggest tags. It is based on the Tag Suggestion jQuery plugin of Remy Sharp.

You can download it from GitHub, just copy the files to the corresponding directories of your existing sfFormExtraPlugin installation or wait for upstream inclusion of my patch.

This widget integrates easily with sfPropelActAsTaggableBehaviorPlugin. Here is how to use it with this plugin.

You must have sfFormExtraPlugin with my patch and sfPropelActAsTaggableBehaviorPlugin properly installed and working. We consider that you have a model called Article with the taggable behavior.

Add jQuery to your javascripts

Like many others sfFormExtraPlugin widgets, the sfWidgetFormJqueryTagSuggestion requires jQuery to work. If you already have it installed, you can skip this step. Either, download jQuery to the web/js/ directory of your project, open the config/view.yml file of your application and set it like that:

Of course, change the filename if needed.

Put Javascripts and CSS into your web directory

sfFormExtraPlugin need some CSS and Javascripts to work properly, run the symfony plugin:publish-assets command to put them into corrects directories.

Create a static function to retrieve matching tags

Its time to extend the TagPeer model class to add it a method allowing to retrieve tags corresponding to a query. Creates a new file called MyTagPeer.class.php into the lib/model/ directory of your project containing the following code:

Do not forget to run symfony cc to clear the cache after that.

Create a controller method to send the result as JSON

We have the model, we need the controller. Create a new module called tag by running symfony generate:module yourapp tag and add the following method to the tagActions class:

Open your routing.yml file and add the following line to be able to access this action:

Modify your form to add the new tags suggestion widget

Open the form class you want to add this widget and add the following line to the end of the configure method:

We use the comma as separator instead of the space by default because this is the separator used by sfPropelActAsTaggableBehaviorPlugin.

Next, modify your call to the form in your actions to pass the AJAX URL as form option:

It’s done!

  1. Hi Kévin,

    Nice idea indeed !

    Why wouldn't you propose a patch on Ymfony's trac in order to ask for the integration of your patch in sfFormExtraPlugin ? Or in sfPropelAstAsTaggableBehaviorPlugin ?

    cheers,

    Xavier
