You have complete access to the DOM with:

getElementsByTagName();
getElementsByClassName();
getElementById();

It should be trivial for you to grab a hold of the element you wish to inject the video duration into with one of those functions.

Any speed benefits of MySQLi over PDO are likely negligible. And you get the benefit of not having to reinvent the wheel, instead having battle-tested code at your disposal. Keep in mind, you can use a factory to determine the strategy your strategy object uses. You might not even need the wrapper i...

Your database idea has already been addressed by PDO. ;) For your mailer idea, you may also want to look into the Strategy Pattern. With that, generally speaking (since design patterns are purposely half-baked) you'd have one mailer object that would act as a wrapper API to various implementations t...

Like most things, factories have their benefits and drawbacks. Have you read up on them? Are there any particular problems you're facing that you think would benefit from implementing one?

Tip: never use the $_REQUEST super global array. It contains everything in GET, POST, and COOKIE. That means if you have something in two or more of those with the same name (which is plausible) you won't know exactly which version you're dealing with. If you have a cookie named 'blah' that contains...

Thanks Nightslyr, if I could +1 that post I would. That was really helpful!! Going from what I read in your post I want to learn C++ for desktop applications, but Java is mainly for Android development, right? Also, what books/tutorials that I could use to start learning C++ and possibly Java (for ...

@Spork, yeah, Mono is pretty great. The biggest issue is that there's still this perception that traditional open source languages (PHP, Python, Ruby, etc.) = *nix stack, while Microsoft languages = Microsoft stack. So, while it's definitely possible to use C#/.NET on linux, good luck finding a team...

C++ is newer than C (you know the post-increment operator? $i++? yeah, that's why C++ is named the way it is). It's not 'better' than C, but rather aimed at doing different things. C is really used for code that has to run close to the metal. Think operating systems. The Linux kernel is written and ...

Singletons are unnecessary in PHP precisely because scripts (generally) have the lifespan of a single request. Add that fact to the fact that objects are passed by reference by default, and all of these singleton repository/database wrapper classes I see floating around in bad code are useless. Ther...

It would probably help if you explained what you mean by 'freeze columns/panes'. Also, what part should be frozen? Why aren't they frozen now?

Finally, is this for layout? Tables should only be used to display tabular data. Using tables for layout is the epitome of doing it wrong.

I'd do something like this: [php]public function logged() { // Note, no 'global'. Why? Because our user object should // have a reference to the db. 'Global' breaks // encapsulation, one of the main components of OOP // Checking if the user is logged in the session table $sql = $this->db-...

You need to swap your quotes around:
PHP Code: [ Select ]
"SELECT * FROM users WHERE email='$email' AND pass='$pass'"
Variables are only interpolated if the entire string itself is double-quoted. You'll also need to fetch your results as mysqli_query simply returns a resource. Finally, you can't mix...

This: Each field may contain more than one value, in which case they will be seperated by a comma. Makes me think you should read this: http://dev.mysql.com/tech-resources/articles/intro-to-normalization.html Comma-separated values in a column is generally a sign you're doing it wrong. This is espec...

A sheet of paper is fragile yet a telephone directory can stop a bullet. Look beyond the weakness of the language and examine its strengths. It took me a week, couple of nights without sleep and coffee so thick you could slice it before I figured out how to do this :lol: . When I have enough posts ...

Post Posted: May 20th, 2011, 11:40 am

Your mistake is that you keep redefining your checkForm function over and over again. The end result is that only your last definition of the function, which checks the last input, actually exists.

You only need one checkForm function. Combine what you have.

*eye twitch at more 'global' parameters*

You may want to look into dependency injection for this kind of thing.

Both are used to facilitate polymorphism. Abstract classes and interfaces create is-a relationships. If a class implements a particular interface, or extends an abstract class, then an object of that class is also considered to be an instance of that interface or abstract class. Unfortunately, since...

FWIW, using a member's registration timestamp as a salt is pretty common. It's unique, and unique to each user. Even better, if you keep that date hidden to everyone except that user when viewing the profile, it's impossible to guess. No one's going to want to brute force every second from the epoch.

That still doesn't stop you from passing your config variables in through a function's argument list. When you have a function like:
Code: [ Select ]
<?php function doSomething($arg1, $arg2) { global $configVar; // code that does something } ?>
You're hiding the fact that the function needs your c...

Post Posted: January 19th, 2011, 1:28 pm

Exactly right. Globals lead to coupling rather than reduce it. They, by definition, break encapsulation. They're a crutch, and in the vast, vast majority of cases, a sign of poor design.

That doesn't stop you from passing the variable in through the function's argument list.

Post Posted: January 14th, 2011, 3:44 pm

Gah, why are you using a global variable? Pass $sys_url through your argument list.

Ack, no, Visual Basic is horrible. If you want to learn a Microsoft language, choose C#.

That said, the description of what you want to do is so general that literally any programming language would suffice.

What are you talking about? This:
PHP Code: [ Select ]
class example { var $name; var $last; }
Is PHP 4 syntax. The keyword 'var' exists only to maintain backwards compatibility with legacy apps, and really shouldn't be used in modern apps as it's the same as declaring a data member public, which is a bad th...
