Having Some Undefined index error problem while making Blog application


Recommended Posts

But i think my logic is okk..

 

Think again, my dear. Right now, your code says this:

  • If the user is logged in, redirect them to the index page and cancel the script.
  • Otherwise (i. e. the user is not logged in), take the nonexistent user ID and store the post.

Sounds like you have it backwards. You want to redirect the user if they're not logged in, otherwise you store the post with the user ID.

This thread is more than a year old. Please don't revive it unless you have something important to add.
