What must be the problem? Im new to php. Thanks guys I'm getting the error "Fatal error: Call to undefined function redirect() in dev/add_comment.php on line 19"
推荐答案
redirect()既不是PHP函数，也不是脚本中定义的函数.如果您尝试重定向，请使用header():
redirect() is neither a PHP function or a defined function in your script. If you are trying to redirect, use header():
header("location: dev/view_post.php?id='.$_GET['id'].'#post-'.mysql_insert_id()");
exit(); //note, I didn't test this for single/double quote accuracy, that's on you
