Prevent access to website during execution of background tasks

Whenever a user visits the homepage, I need to verify that default values on the database are in place (if this is not the correct location for the check, please advise). Here's what needs to happen:

  1. Determine if the database is empty (if not, skip steps 2 and 3)
  2. Disable access to the entire page
  3. Populate the database with default values
  4. If successful, re-enable page access

I am unsure about step 1 (where to perform the check), step 2 (actions needed), and step 4 (effective disabling and enabling of the page)

Answer №1

In response to your inquiries: 1. It may not be incorrect, but there are certainly more efficient methods available. I recommend verifying this information only once during login and utilizing session storage for the value [database exist true/false]. 2. Depending on what you mean by disabling the entire page - whether it's making elements invisible or unclickable - you can assign a specific class to the div and easily toggle it using jQuery. 3. Once again, this action could be performed just once upon login. 4. When implemented correctly, you will be able to activate this feature within your jQuery expression.

Answer №2

$(function() {
       var h = $(window).height();
       $("body").append("<div id='overlay'></div>");

       $("#overlay")
         .height(h)
         .css({
              'opacity' : 0.6,
               'position': 'fixed',   
               'top': 0,
               'left': 0, 
               'background-color': 'black',
                'width': '100%',
               });
    });

To re-enable your page, simply remove this overlay div element as a child of the body tag.

Answer №3

During your background process, consider implementing website disabling using jQuery BlockUI or a similar tool. Check out this link for more information: http://www.example.com/tools/blockui

Answer №4

It seems like there may be a solution to your issue by using PHP to check the start of your file and customize the output based on that. There's no need to disable the page completely, as any background processes can still occur on the server side during website assembly. Could you provide more details about your specific problem?

Here's a basic pseudocode example:

<?php 
if($category == "home"){

  << Check if database is empty >>
  if($empty == false)
    << Fill default values in the database >>

  << Display the page contents >>
}
?>
