how to show the error message on the client side if the server-side = " $action->invalid();"
thx
You can use
on server side
$action->set_response_text(" error message text here “);
$action->invalid();
on client side, add next line to dataprocessor init
dp.defineAction(“invalid”,function(tag){ //tag - XML tag which contains error details
var text = tag.firstChild?tag.firstChild.data:”";
if (text) alert(text);
return true;
})
Instead of text, in above scenario, set_response_attribute can be used, it will made access data on client side is less cryptic, but it has limitation on content.
Some more info can be obtained from
