All lovers of Symfony knows that it does not have a filter component.
There are wonderful and comfortable Constraints and even was an attempt to create a filter component with same logic (issue filters on Github), but no one took to do it.
When I once again faced with the task of filtering large amounts of data from a user, I realized that it is time to solve the problem of how to filter data more global/nice/comfortable.
After some research, I realized that there is nothing fundamentally new in filtering on php. There are 2 popular components:
Please note that the last one is not very well supported by the author.
There symfony bundle for DMS-Filter but it is not compatible with the Symfony 3. I did not like the code for DMS-Filter. I understand that can do everything a little easier.
After analyzing the situation, I realized that the fastest and most reliable way to write a filter bundle, are using the well-documented and test coverage filters -Zend Filters. Just want to add, that in the past, I have worked with Zend Framework 1 and this component was close and clear for me.
I wanted to make the logic of the filters similarly to Symfony Constraints.
The result was written bundle, which adds a service that can be used to filter the object based on the annotations. Also, bundle can filter form object if it is annotated.
Documentation that I used at the time of writing this bundle:
How to Create a Form Type Extension
Form Events
How to Dynamically Modify Forms Using Form Events
How to Register Event Listeners and Subscribers
Documentation and bundle can be found on GitHub FilterBundle.
