I was working on a small project that was hosted on site with SSL installed and enforced. However I noticed that the Secure text and lock icon does not appear, instead I get the Info or Warning sign at the address bar.
After a few minutes of combing through the code (using a manual select, skip and test technique), I discovered a code segment that crashes the connection.
<form name="frm_name" id="frm_id" method="post" action="http://link/to/site">
// ...
</form>
To resolve this, I replaced the text http:// with https://, and the secure connection was OK. So I went about resolving the link string to use the HTTP protocol of the server.
<?php
$http_str = 'http';
if (isset($_SERVER['HTTPS']) && ($_SERVER['HTTPS'] == 'on'))
{
// secure connection on
$http_str = 'https';
}
$http_str .= '://'
// the server name
. $_SERVER['SERVER_NAME']
// the php file and location
. '/'.$_SERVER['PHP_SELF']
// the GET variables and values
. $_SERVER['QUERY_STRING']
;
?>
<form name="frm_name" id="frm_id" method="post" action="<?php echo $http_str; ?>">
// ...
</form>
