Question

How can I show or hide div depending on result come from server, in the file that handle the request, I get a customer object from db, depending on user request, if I didn’t find the corresponding customer I want to hide a div .

here’s my php code

 $customer=getCustomerViaCellPhone($link,$cellPhoneNo);
if(!$customer){
   $error = 'No result found';
}

here’s the view

<div id="customerInfo" class="<?php (is_null($customer))?'hide':''?>">
....
</div>

but it shows the div in both cases

Answer 1

You are missing the command echo in your example so it should be:

<div id="customerInfo" class="<?php echo (is_null($customer))?'hide':''?>">
....
</div>

obviously your css would also need to define a class called .hide that had display:hidden; in it.
