Sonata Admin - adding help message in filters

Question

I want to add a help message in the filters form.

I'm able to do it in the edition form, like this:

<?php
public function configureFormFields(FormMapper $formMapper)
{
    $formMapper->add('name', null, array('help'=>'Help Message'));
}

but that doesn't work on the filters

<?php
public function configureDatagridFilters(DatagridMapper $datagridMapper)
{
    $datagridMapper->add('name', null, array('help'=>'Help Message'));
}

I've also tried the sonata_help option, but it doesn't work..

is there a way to add a help message in the filters form (without making modifications on templates)?

Answer 1

If you don't want override templates, you can use basic jQuery for add attributes to your filters on load page. (create a script and add it to assets config)

Exemple :

jQuery(function(){
    $('#filter_someproperty_value').attr('help', 'Your help text');
});

It's quick and not very clean, but it works and it's simple.
