if ( isset($_POST) ) {
}
how to do filter_has_var function to check if $_POST exist and have value?

If the originating web page has issues a POST, then
$_SERVER['REQUEST_METHOD'] will equal 'POST'
Your php code can only extract from the POST values that were set by
the web page when it issued the POST. It can't demand a specific value,
but it can establish whether or not the page supplied a specific value.
Say, for instance, you expect that the page will supply a text string
in a variable called 'TextString', you can check to see if $_POST['TextString'] is set, and validate it's contents.
So, your php logic might look like
if ($_SERVER['REQUEST_METHOD'] == "POST")
{
if (isset($_POST['TextString']))
{
/* validate the contents of $_POST['TextString'] */
}
else
{
/* page didn't supply 'TextString'. Handle this situation */
}
}
else
{
/* page didn't POST. Handle the situation. */
}
