I think the error that the clear link doesn't work in a grid with a checkbox column is in the generated JavaScript.

As the onclick seems to be handled before the link target, it always returns false, which stops opening the link's href URL.

// ~ line 259:
function cbcwr_clearFields() {
    try
    {    
        $('#{$this->grid->id} :input').clearFields(); // this will clear all input in the current grid
        {$_beforeAjax} $('#{$this->grid->id} :input').first().trigger('change');// to submit the form
        /**
         * CHANGE from 'false' to 'true' below:
         */
        return true;
    }
    catch(cbwr_err)
    {
        return false;
    }
}

P.S. not sure why the link works at all without a checkbox column? ;-)

if add check box column to the grid view clear filter is not working please help me..

Please address questions in the forum. The answer for your questions has been posted here

Thank you very much for this one.

Question: How to clear the search form fields also?

TIA!

@artur_oliveira : I am also having this problem, and just solved it.

@pentium10: please merge this solution into the next version of your excellent extension.

in init(): replace

$this->buttons=array(
            'clear' => $this->_clearButton,
        );

with

$this->buttons=CMap::mergeArray(
            $this->buttons,
            array('clear' => $this->_clearButton,)
        );

this will preserve the existing button definitions while added the new "clear" button.

I believe this extension does not work with customized buttons

Thanks for a great extension! I have found it to be very useful in many circumstances.

However, I now have a problem with a view that contains two gridViews. I assigned an EButtonColumnWithClearFilters to each of the two grids. Unfortunately, the clear button only works for the second gridview. When I click the button on the first view, it actually clears the filters on the second view.

Is there an easy workaround?

Thanx!

Hello,

I think in the init() method there is a small type setting the URL of the 'Clear Filter' button:

This code ...

if (!empty($imageUrl)) {
    $_imageUrl=$this->imageUrl;
} else {
    $_imageUrl=$this->grid->baseScriptUrl.'/delete.png';
}

should be changed to

if (!empty($this->imageUrl)) {
    $_imageUrl=$this->imageUrl;
} else {
    $_imageUrl=$this->grid->baseScriptUrl.'/delete.png';
}

Regards,

Joachim

@jeremy I don't understood your issue and why you need fix by removing something that needs to be there for some scenarios. Could you please elaborate on this in the forum, and we will continue discussing there.

Further to my last post, I understand the intended behavior of unsetFilters(), but in fact it is never getting called as long as javascript is enabled. The js attached to the "clear filters" link/image is invoked, which clears the filter fields at top of grid, and submits the form. The link with ...clearFilters=1 is never invoked, hence the controller logic to call clearFilters() is never called.

The net effect is that while the filters are cleared faster, they persist in user state. If the user navigates offpage, then returns to the page, the filters s/he previously set are still in place.

I fixed this in my copy simply by removing the javascript function definition ($script=<<HTMLEND...HTMLEND;). Now actionAdmin() does things properly; the filters are cleared in user state, and the page reloads.

It's a bit less efficient than the js method; but I can't see how to get the state cleared otherwise. Suggestions ?

@jeremy You need to have the code to clearFilters() for the case when you don't use RememberFiltersExtension, and you only use ClearFiltersExtension on it's own.

unsetFilters() needs to be called to clear the variables from the $_SESSION where the RememberFiltersExtensions stores them between navigation.

I commented-out the code from actionAdmin() to clear the filters; but it still works properly. I can only assume the javascript functions are clearing the filters.

Why is it necessary to have the clearFilters=1 parameter, and the controller logic as specified in "Step 2" of the instructions, and EButtonColumnsWithClearFilters.clearFilters(), and ERememberFiltersBehavior.unsetFilters() ?

@adinugro You can use whatever text or object you want, but you have to link to your controller with 'clearFilters' parameter set to '1'

hi,

how can I use the button if I am not using button column? I do not have any CButtonColumn in my CGridView, since I am implementing {delete, view and update} using my own custom links.

I want it to displayed in the filter of my other column.

Cheers,

Another very useful extension, paired with RememberFiltersGridview.

One small enhancement is to hide/show the "Clear" button depending on whether the parent grid has any filters set:

// set visibility based on presence of filter values in parent grid
        if (empty($this->clearVisible)) {
            $filterString=implode('',$this->grid->filter->attributes); 
            $this->clearVisible = !(empty($filterString));
        }
        // continue...
        $_visible=is_bool($this->clearVisible)?($this->clearVisible)?'true':'false'):$this->clearVisible;
