Does everyone else find themselves constantly typing ampersands in every function definition and assignment when dealing with (potentially) large data structures (usually database result sets)? It's so annoying  . I wish we could either get actual pointers or real references.

Do you guys know the text field on the upper right of the main page on Facebook, the friend search? It auto suggests names from your own friends as you type. Is there some way to do this with PHP/MySQL for my own site? I'm making a site for inputting songs as they're played (college radio station, yay) and would like some way to suggest the correct spelling/formatting of songs and artists (pulled from a database) so that we don't end up with 15 different entries for "Beatles" "The Beatles" "Beetles" "Beatls" etc.

I would probably do something with jQuery that ties an AJAX request to an onkeyup event for that input field. That AJAX request would run a PHP script that returns suggestions in JSON format. You would definitely have to optimize it so that it's not running a MySQL query every single time somebody presses a key. (Maybe once every 3-5 seconds while typing is better) Zorilla fucked around with this message at 18:44 on Dec 27, 2008 |

Another dumb PHP question -- is there a function for finding out the current page being displayed? As in, let's say I want to do a standard "footer.php" and include it with each page, but not include a link to the current page. Is there a simple way to find that out?

Emo.fm posted:Thanks, I will look into this. $_SERVER['REQUEST_URI'] is usually what was typed in the address bar to get to the page, and $_SERVER['PHP_SELF'] is usually the main or "parent" page (meaning, if index.php includes footer.php, PHP_SELF on either page will be index.php). Server configuration changes the values and formats of those variables, so you might just want to make a page that spits out phpinfo() and look at the variables yourself. Some servers give multiple formats for the same information, so it might be easier to match one or the other to the link hrefs as you echo them.

Let's say you have a User class and an Article class and you want a function that returns all the articles a user has written. Does it go in the Article class as something like Article::getArticlesByUser($user) or in the User class like $user->getArticles()? What makes more sense?

Does it go in the Article class as something like Article::getArticlesByUser($user) or in the User class like $user->getArticles()? What makes more sense? I was about to say "depends", but in this case it really doesn't. $user->articles(); is fine. Article::articles_by_a_user(); makes little sense. Think of it like this; once you "have" a user, it makes sense (in the vague context of a system that stores articles by users) to find all the articles by a user. I can think of a strong user case where I'd want to do that, and I can imagine I might have an instance of a user then too. (I can think of 2 clear cases; show more articles by current article's author, or when author logged in, show my articles) On the other hand (and I'll be honest we've only got the name of the class Article, singular, to go on) it seems you've conceived of an abstraction for A USER and one for AN ARTICLE,singular in both cases. A function belonging to a singular abstraction that returns a set of (somethings) which is related to that instance; this makes sense. A static function of a singular abrstraction that produces a set of that type of object, related to an instance of a different type? Nonsensical. In fact I feel I've kind of aswered this before? I think you would be well served by a book on OO, preferably one well separated from any specifics of a language you are interested in programming in. It also occurs that you might want to look into the concepts of factories, or at least become open to the idea of using multiple abstractions for the same "thing". i.e. how about 2 classes; Article and Articles; the former to abstract an individual and specific article, the second to abstract the colection of all articles, and provide functions that produce sub-collections (as, say, arrays of Article) So you could have Articles::by_author($user_id) which returns an array[Article]... This would then also be the logical place to put Articles::most_recent(10); and Articles::awaiting_publishing(); etc etc (note these may well NOT actually want to be static functions, and in terms of MVC Article and Articles are both models, which give different interfaces to the same resource...)

I can't see what data this object would contain except that of an array of objects of type "Article"... I fail to see the necessity of creating something like Articles::most_recent(int) when Article::most_recent(int) would make just as much sense.

Atom posted:I fail to see the necessity of creating something like Articles::most_recent(int) when Article::most_recent(int) would make just as much sense. It seems like OOP dogma more than anything practical imho. There's no 'necessity' its a nicety of abstraction. In the cold light of pure practicality there's no need to seperate the abstraction of the collection of items from the abstraction of the items themselves. (just as there's no 'necessity' to write in an OO style in PHP at all, you could even still implement MVC in a purely procedural programming method, probably clumsy, but you could do it if it suited your purpose) On the other hand, it can serve a purpose to seperate into 2 abstractions the functionality that applies to the group from that which applies to the individual. Example; changing the headline of an article probably 'belongs' in an abstraction for the article as an individual item, but finding all articles with a given feature is (potentially) a feature of the group of articles as a whole. Further example, you could possibly write this pair of classes so that modifying the implementation of one did not imply a need to change the implementation of the other - and in some cases that alone might be reason to split into 2 classes. Conversely, considerations of further (as in to come at a later date) extensions to Article might mean that having it all wrapped up in one class to inherit from was helpful. It really come down to; there needs to be an underlying understanding of the flow of your data, the structure of your data and the intended (and expected) use cases for the classes and objects your making. This all gels together to give you a 'feel' of what is the correct abstraction for your application. The question (certainly when taken in combination with the poster's previous one) was taken in a sense of 'what would you do?' Hence my comment about the OO book; not meaning to imply 'and then you too would understand the ONE TRUE ABSTRACTION for users and articles in all systems' but that this would be the place to look for a wider view of how to go about crafting the abstractions that will work for the specific app at hand; because there are many perfectly valid ways to abstract authors and articles (I mean; is this a 1-1, 1-M, M-1 or M-M relationship in this application? Is this even decided yet? Because that would change EVERYTHING!) I've certainly never considered myself dogmatic about OO (slack about it, yes, dogmatic - no) I gave an answer of how I would do it, why I would do it that way, and why I wouldn't do it the other way - and a suggestion to go look at other ways - where the dogma at? Edit; and my god I can witter on about this stuff

I don't do a lot with timezones, honestly (its a perk of living in GMT - just make everything Zulu and forget about it) But; when I do, I simply... 1-store all times as Zulu 2-manually offset by any required timezone offset using the magic of addition and subtraction, at the point the offset is required (i.e. I brute force it) I'm probably anomalous though, because I tend not to use stuff thats only in PHP 5, because of ending up wanting to get my code running on clients' lovely shared hosting that they will not change. So I tend to use time() and microtime() and strftime() more than maybe is normal/sane. p.s. I use the same methods for currencies (store all as GBP and convert as required) and measures (SI units and convert).

$cat->stuff();

I'm looking for something to help with my daily work tasks, as well as recording the information I find while doing these tasks. I need to check server hard drive usages, modify certain profile information, clean out workstations at specific time intervals, etc. I'm looking for some kind of task or to do site I can set up with PHP and MySQL where I can automate things a bit. I need tasks that repeat daily (but not on weekends, more configuration options would be nice), the ability to add one time tasks, and be able to go back to show that I did what was supposed to be done. This will be for my use only, others won't be able to log in and create their own tasks. Anyone know if such a thing exists?

Cause Remember The Milk does all that stuff you said and more, and is free. You can specify tasks to repeat "every day", "every weekday", or even "every month on the 2nd last Friday". Tasks can have subtasks (or not), and you can keep finished tasks to take a look at past progress.

I'm in no way a coder, I just play with Joomla and edit other people's hard work. I'm having an issue with a template I've been working with and I was hoping someone could give me a hand. The site is here: (alttabbed.net is not my site) http://www.alttabbed.net/revdemo This is a Joomla site with the "Simplix" template installed from Rockettheme. I've been tweeking it for the last couple days and it's almost looking exactly how I want. The image is the article and the text and the menu are in modules. My hope was to be able to get them all to line up, top and bottom, however if I extend the image to it's full height of 450 (the height of the two modules), the middle module extends down further for no reason whatsoever. I think this may be a padding/margin thing but I'm an idiot and can't find anything related to that in the CSS file. The image also seems to start a couple pixels below the modules. Also, in Firefox and a few other browsers the site looks fine, but in IE7/8 it only takes up 3/4 of the screen and the rest is white. I know I can't explain poo poo very well, but if someone is familiar with Joomla and could help me out it would be greatly appreciated. edit: Well, I fixed the to alignment, but the middle module still extends when the image is set to 500px. IE/Chrome issue, I still have no idea. edit2: I think I fixed everything. Envy Insanity fucked around with this message at 17:28 on Jan 1, 2009 |

Awesome, thanks. I fixed those and noticed I had the semicolon inside the boundary definition which was obviously breaking it as well. Now I've got it working. Both the HTML and text parts of the mail message are showing up, however I was under the impression that only one part should appear, depending on if the user has HTML message enabled or not. As it is, in my HTML enabled gmail window, both parts of the message are showing, and in a client with HTML disabled, both parts are also showing and all the HTML code is appearing as text.

It's not as lightweight as EditPlus, but I imagine that would be true of any IDE that can outline objects and complete code. It's nowhere near as heavyweight as Eclipse or Visual Studio, either. So far I'm really impressed. I downloaded a massive project (around 10MB of source code) for local development. Frankly, I expected PhpEd to get a little confused about the class hierarchy. I opened a script and instantiated a derived class that depends on an autoload function for inclusion. The editor gave me all of its public members without a hiccup. It includes doc comments in the code completion if they exist (method and argument descriptions, etc.). And this is on an antiquated Thinkpad running XP Pro with 512MB of RAM. Unfortunately, it's also not as cheap as EditPlus, but a free trial is available. DaTroof fucked around with this message at 00:56 on Jan 5, 2009 |
