Your logic is skewed, if the URL is:

http://localhost/zblog/source.php?srcid=1

then you aren't passing the title but if the URL like this:

http://localhost/zblog/source.php?title=some-title

then your if statement will never run because:

if(isset($_GET['srcid'])) {

it relies on $_GET['srcid'].

If you want to use the title then amend that if statement to look for $_GET['title'] instead of $_GET['srcid'] or, try passing both parameters in the URL together.
