Frederic Offline Senior Member Posts: 56 Karma: 0	Hi, I'll appreciate greatly a help on that one... The idea is to reset the search fields programmaticaly when the user has selected a new category. In JS, there is the "Joomla.resetFilters();" function. Is there something that can be called in PHP ? Thanks in advance, Best, Fred

Some leads :
1°) In the yourview_filters.php, there is a button that uses onclick :

<button onclick="resetFilters()"><?php echo(JText::_("JSEARCH_FILTER_CLEAR")); ?></button>

then jQuery in the same file, you have, at the top

function resetFilters()

2°) In the view.html.php, you have :

$this->filters['name of the filter']->value = $model->getState("filter.name of the filter");

so maybe you could set the value yourself there

It would be nice to be able to flush a filter's view from another view but in this case $this->filter will contains the current filter's view and not the one I would like to fflush... I have to think to a way... Best, Fred

So, change the context.

$model->set('context', 'another_context');

Context can be any string.

Then, in prepareQuery(), you just have to change few things to filter differently for this context.

You can also use state vars.

$model->setState('myStateVar', true);

Than, check this state var to filter or not.
In few words, do what you want in the prepareQuery() function. But the parameters must be sent through states vars or simply the context.

Coding is now a piece of cake
