I wanted to create a disable / enable a dropdown list depending on whether a radio button is checked
Is there an easy way to do that ?

[Henri72]

Any idea ?

HI,
Henri72 and welcome to the forum .

//it's controller's code





$crud = new grocery_CRUD();

$crud->set_table('videos');

$crud->set_relation('videos_parent','videos_groups','title');





// field "check" is checkbox which will show/hide dropdown



$f=array('check','videos_parent','file_name','videos_title');



$crud->add_fields($f);

$crud->edit_fields($f);



$crud->callback_edit_field('check',array($this,'callback_check'));

$output = $crud->render();

the callback funciton returns a checkbox and javascript code

function callback_check()

{

return '



<script type="text/javascript">



$(document).ready(function(){



$("#ch").click(function(){

if ($("#ch").is(":checked")==false){

$("#videos_parent_field_box").hide(200);

}else{

$("#videos_parent_field_box").show("");

}

})

})

</script>

<input type="checkbox" name="ch" id="ch" />';

}

This code show/hide a dropdown list, but you can change it as you like.

Dear victor,

 

Thank you for this! It helped me a lot  :)

 

Other topic, can I create a dynamic $where condition for the set_relation_n_n? I needed my set_relation_n_n to be dependent on a drop down so I was thinking of a way to make my $where condition to be dynamic... Can u help me? I did my research but I still cannot get it right...

 

Thanks in advance!
