PHP Prevent submit until some time

To prevent submission of form or any script we can use PHP Session to prevent concurrent submission.

if (isset($_POST) && !empty($_POST)) 
{
    if (isset($_SESSION['posttimer']))
    {
        if ( (time() - $_SESSION['posttimer']) <= 2)
        {
            // less then 2 seconds since last post
        }
        else
        {
            // more than 2 seconds since last post
        }
    }
    $_SESSION['posttimer'] = time();
}

SSL-certificate; Green lock not displaying

My best guess would be that your page contains some non-https content.

Add Following meta value to your header. Basically it will force non HTTPS to use HTTPS secure connection url.

If you want to allow the Mixed Content request, then add the below tag into tag.

<meta http-equiv="Content-Security-Policy" content="upgrade-insecure-requests">

If you want to block then add the below tag into the tag

<meta http-equiv="Content-Security-Policy" content="block-all-mixed-content">

CORS header 'Access-Control-Allow-Origin' missing

ERROR : Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://www.SOMEURL (Reason: CORS header 'Access-Control-Allow-Origin' missing).

.
When the code send the request, you shall have a "200 OK" response code in your browser console, which means that the resource is accessed, but it does not grant the right to share that resource. It does this by not allowing "Access-Control-Allow-Origin".

To change that, you have to write this in the .htaccess of the requested domain file (notyourdomain.com):

Add following code to your .HTACCESS file

<IfModule mod_headers.c>
Header set Access-Control-Allow-Origin "*"
</IfModule>
