I ended up not following through with my plan to try making a simple Blog again. I was planning to do it in order to show my skills for potential web dev jobs, but not long after I posted about it I realized I just wasn’t interested in that kind of work. I wanted to refocus on my video game development, so I’ve been doing that instead. I haven’t been updating this blog with my progress, though.
So it’s been years since I worked on my SimpleBlog project. I’ve decided to start a new project with the same name. The project is relatively simple; to create a minimal blog demo using ASP.NET and host it wherever I can find a spot. Right now I’m looking at IBM’s VPN Cloud, Microsoft Azure, and Google’s VPN Cloud as trial beds. Maybe also Amazon Web Services; they’re pretty popular professionally, but they don’t have an unlimited free VPN like those first three. Unless they do, in the future when you’re reading this.
I’ll post links once I’ve got the basic app up somewhere.
4:30pm – This’ll be a short work session since I have to be somewhere in less than an hour, but I want to try and solve the AJAX error if I can before that. I’ve already taken a look at it and I’ve got no clue what’s going wrong. I don’t see any new code that would interfere with the jquery get function, yet it returns a fail result. So, I’ve gotta figure out under what conditions it could fail.
4:33pm – Oho! I found the problem. When I went to the php page itself it gave a syntax error. That explains it. That should be easy enoug to fix.
4:35pm – It doesn’t seem to have a syntax error in the file itself. I’ll try re-uploading it in case I don’t have the most recent version on the server.
4:46pm – Well I’ve gotten rid of the AJAX error but I still don’t have any posts showing. I wonder why that could be.
5:01pm – The AJAX error is gone, it was mostly a bunch of syntax errors in the PHP. But now it’s not putting up any posts and it’s not giving any errors. I added a data dump to console and found that it was getting a false result from the PHP script. That means the database connection isn’t working properly, in one of a few ways. It’ll take some effort to figure out what’s going wrong there, and I’m low on time, so I’m going to head out.
3:15pm – Well, my problem mysteriously resolved itself when I cleared my cookies, which makes as little sense as the problem itself. For now I’m going to ignore it, since there’s nothing I can do, and continue programming. There’s a bug with the cookie anyways, so I need to implement a logout function. I’ll do that now.
3:35pm – I’m having trouble figuring out how to end the session when I’m doing the PHP side as a web service. I’m not sure but I think I’m going to have my sessions never end, server-side, while they end locally in browser, because it’s impossible to always have the browser close out sessions at the end. I’m not sure if this isn’t how the thing’s meant to be used either.
For now I’m going to do this the easy way and see if anything goes wrong.
4:07pm – Well the logout seems to be working fine. The cafe’s internet isn’t, though. It takes a while to load anything, if it loads at all… And it’s uncomfortably hot. I don’t think I’ll stick around for the second hour like I planned.
The next thing I need to do is figure out how I broke the basic post display, and fix it.
7:48pm – Some friends gave me some suggestions for my null != null is true problem, so I’ll give them a try.
8:19pm – No dice. Even when I have it as if(sessionID) and sessionID is null,
8:24pm – I’ve made progress! It’s a browser issue. In FireFox it works perfectly, but in Chrome it fails miserably.
8:33pm – Well that’s as far as I’ve been able to get. This really has me stumpped. I tried switching over to the !== operator but that doesn’t do any different. In Chrome, null !== null is true, and in Firefox null !== null is false.
3:51pm – When I last left my Simpleblog, everything had broken. It thinks it’s logged in when it shouldn’t, and it throws an AJAX Error when it tries to download/display the posts. No more javascript errors though.
4:09pm – I put some console outputs into the code. For some reason the sessionID is coming out as null. Not sure how that’s happening…
4:16pm – Okay WHAT!? if(sessionID != null) is being passed even though sessionID is null. It being null is the only time that it should not pass! Debugging is one thing but I don’t know how to fix it when it’s clearly defying a logic gate. >.< 4:26pm - I've tested null comparison outside of my project and it works fine. Why doesn't it work here? It doesn't make sense! Argh. 4:28pm - if(null != null) console.log ("null != null"); doesn't print to console, so why does it evaluate as true immediately after? I have it printing sessionID to console immediately before the comparison; it's null, and yet null != null is proving true. Why? 4:33pm - It's google time. Here's something from StackOverflow... No that doesn't help. I don't see anything else that's like my problem. Shoot. I'm completely stumped, here. I'm going to give up for now and think about it, and maybe some friends will have an idea.
10:29am- I finally have internet at the cafe I’m working at. I’ve been working for about a half hour aready, working on the login function JavaScript. I’m about to make some modifications to the php login function to stop code insertion.
11:44am- I’ve been working quite a while and haven’t tested anything. I’m sure something will go wrong with this code, and debugging it is going to be a pain. I’m still working on the login function. Right now I’m working on the part where it shows the hidden logged in options bar and hides the login form.
12:13pm- Now I’ve got it so that if there’s a session ID cookie it displays as if you’re logged in. It’s getting close to test time.
12:20pm- Test time! Also lunch time. I’ll be debugging until my food gets here. I’ve got my first bug too. The login form is nolonger displaying to the right of the page with the CSS Formatting.
1:14pm- Well I got the javascript errors cleared out, but now it’s throwing ajax errors displaying the entries. Unfortunately I’ve hit my limit, it’s hard to keep my eyes open. I need a nap, so this is where I’m calling it for now.
Well I’ve finally found time to work on my SimpleBlog project again. Well, this isn’t the only time. Last time I worked on it, I didn’t save my notes, so I’ll summarize here.
I added a CheckLogin function to model_SimpleBlog to check the login data, and removed the checkLogin function from controller_SimpleBlog.php because its unneccesary now. The web app will know it’s logged in because it’ll have a session id, or it won’t. Checking the login data will happen on login.
9:51am- Getting started. The work I did last time has got the groundwork done for logging in and returning a Session ID. Now I need to make the login form work and make the system check for a cookie with a session id. I’ll start with the latter part.
10:47am- Okay it now checks for a session ID in the cookie when the page loads, and if it finds one it assumes the user is logged in. Next I need to make the login form work, but that’ll have to wait for next time. I just remembered something I had to do at home.
