[Typing Problem, Shifting]

I did not notice the scrollbars within the input elements.

Are you satisfied with my answer, or do you still need help?

[Typing Problem, Shifting]

When you have the vertical margins, does that make the page always have a scrollbar no matter what?

If so, then there is your answer.

 

Also, if someone shrunk their screen enough horizontally, then you would see a horizontal scrollbar too.

[Typing Problem, Shifting]

I can't reproduce the problem, but if the shift is slight, I would guess it's because you're going from no vertical scrollbar to a vertical scrollbar.

 

That behavior depends on your window size and browser though, and is essentially unavoidable.

You should use the mysqli_query function.

 

Also, please read all the posts from Larry and me above, and carefully try everything we mentioned.

Your answer is in there somewhere.

If you're sure the query itself is okay and you suspect that the cookie is the problem, then use print_r to echo out the contents of $_COOKIE, and go from there.

[Php If Statement - Syntax Causes Form Changes]

Hello and welcome to the forums. You're getting spaces because you have spaces in your HTML before the <?php tag and after the ?> tag.

If you remove those spaces, you won't get the extra spaces in the input value.

[Login Script - Same Page Ajax Request]

In the success callback of your Ajax call, check for some sort of returned flag, and use location.assign to change the URL.

[Login Script - Same Page Ajax Request]

I would advise against your current approach for reasons that are likely already obvious to you.

Nowadays, I quite often structure my index.php file as follows for any Ajax-driven pages:

 

<?php
  
  // Include config file.
  
  // Maybe do some security checks.
  
  // List array of CSS files to include.
  // List array of JS files to include.
  
  // Include header.
  // Include content.
  // Include footer.

 

I then structure my content include so that it loads all the necessary content on page load, but I can also make Ajax requests to the same script, and depending on the request, I can easily route it to return the HTML I desire.

 

With that said, depending on the complexity of the page, I very well may have additional scripts for handling Ajax POST requests that insert into or update the DB, so don't feel like you have to or attempt to cram all your functionality into one script.

If all your files are well organized, having multiple files to handle a page is not a bad thing.

Hello and welcome to the forums.

 

What folder is the hello.php file in and what URL did you use to access it?

Thanks.

[Login Script - Same Page Ajax Request]

Assuming you're using a modern browser, check out the Network tab in your dev tools / console, and see what it says when you make the Ajax request.

[Javascript Regular Expression Performance]

Use the test method when you just want to check for a match, and use match when you actually want to get the match(es) back.

The literal syntax (i.e., //) will always be faster than the new RegExp syntax, and as such, I only use new RegExp when I need to embed a variable in my regex.

Very good.

Thanks for sharing.

[Chapter 8; Script 8.4 Problem]

Yes, remove the backslashes in your query, and make sure that the values of $e and $p are properly set.

Do you also have the meta charset tag set to UTF-8 or have to added a UTF-8 Content-Type header via PHP?

[Echoing Sorted Array With <Option> Tag]

After your sort function call, do the following then:

echo '<pre>';
print_r($sk);
echo '</pre>';

[Echoing Sorted Array With <Option> Tag]

You need to wrap the option elements in a select element.

Well said, Larry.

[Ultimate Session Wrapper Class]

Thanks for the response, Larry.

I think those are fair statements, but I still feel like the same thing can be easily accomplished with procedural code.

 

Of course, with procedural code, you have to be more disciplined with namespacing, the hierarchy you set up with helper functions, etc. (because the code won't automatically do it for you like OOP does), but I think that the benefit of procedural code (like you eluded to) is that it is easier to learn, quicker to write, and less bloated.

 

Really, when it comes down to it, I think that well written code, whether it be OOP or procedural, is going to be quite similar in structure, but with that said, I just find procedural to be less time-consuming and less bloated, which is why I tend to prefer it (at least in PHP and what I use PHP for).

 

Anyway, thanks a lot for sharing your thoughts.

[Chapter 8; Script 8.4 Problem]

A 500 error means that there is a syntax error in your PHP that has to be fixed.

As for echoing the UPDATE query, I mean if you have a query like the following:

UPDATE users SET name = 'Bob' WHERE id = $user_id;

Then do the following in your PHP script:

echo "UPDATE users SET name = 'Bob' WHERE id = $user_id;";

Doing so will allow you to see the exact query you're executing on the DB, and you can then copy and paste that into phpMyAdmin, and run the query directly on the DB, which will provide more feedback in terms of whether there is an error in the actual SQL, etc.

I just wrote up a long response in reply to your points, Antonio and Larry, but the more I read and re-read my write-up, the more I realized that my thoughts boiled down to one, underlying question:

Why does OOP make bigger, complex projects easier to maintain?

 

I ask because I have worked on some massive PHP projects, and I have yet to ever see a case where OOP simplified things.

On the flip side, in every case I've ever used or seen OOP in PHP, I feel like it's added a lot of bloat to the code, and by direct correlation, dev time.

Certainly, if you don't use OOP, then you need some logical way of organizing your code, but that to me does not imply that OOP is better.

 

So, to keep this discussion going and interesting, please tell me specifically how OOP makes bigger/complex projects easier than if procedural code is used.

 

Thanks.
