  • Passing arguments and conditions to model in codeigniter

    - by stormdrain
    I'm adding some models to a project, and was wondering if there is a "best practice" kind of approach to creating models: Does it make sense to create a function for each specific query? I was starting to do this, then had the idea of creating a generic function that I could pass parameters to. e.g: Instead of function getClients(){ return $this->db->query('SELECT client_id,last FROM Names ORDER BY id DESC'); } function getClientNames($clid){ return $this->db->query('SELECT * FROM Names WHERE client_id = '.$clid); } function getClientName($nameID){ return $this->db->query('SELECT * FROM Names WHERE id ='.$nameID); } } Something like function getNameData($args,$cond){ if($cond==''){ $q=$this->db->query('SELECT '.$args.' FROM Names'); return $q; }else{ $q=$this->db->query('SELECT '.$args.' FROM Names WHERE '.$cond); return $q; } } where I can pass the fields and conditions (if applicable) to the model. Is there a reason the latter example would be a bad idea? Thanks!

  • Compare array in loop

    - by user3626084
    I have 2 arrays with different sizes, in some cases one array can have more elements than the other array. However, I always need to compare the arrays using the same id. I need to get the other value with the same id in the other array I have tried this, but the problem happens when I compare the two arrays in a loop when the other array has more elements than one, because duplicate the loop and data , and it does not work. Here is what I've tried: <?php /// Actual Data Arrays /// $data_1=array("a1-fruits","b1-apple","c1-banana","d1-chocolate","e1-pear"); $data_2=array("b1-cars","e1-eggs"); /// for ($i=0;$i<count($data_1);$i++) { /// Explode ID $data_1 /// $exp_id=explode("-",$data_1[$i]); /// for ($h=0;$h<count($data_2);$h++) { /// Explode ID $data_2 /// $exp_id2=explode("-",$data_2[$h]); /// if ($exp_id[0]=="".$exp_id2[0]."") { print "".$data_2[$h].""; print "<br>"; } else { print "".$data_1[$i].""; print "<br>"; } /// } /// } ?> I want the following values : "a1-fruits" "b1-cars" "c1-banana" "d1-chocolate" "e1-eggs" Yet, I get this (which isn't what I want): a1-fruits a1-fruits b1-cars b1-apple c1-banana c1-banana d1-chocolate d1-chocolate e1-pear e1-eggs I tried everything I know and try to understand how I can do this because I don't understand how to compare these two arrays. The other problem is when one size has more elements than the other, the comparison always gives an error. I FIND THE SOLUTION TO THIS AND WORKING IN ALL : <?php /// Actual Data Arrays /// $data_1=array("a1-fruits","b1-apple","c1-banana","d1-chocolate","e1-pear"); $data_2=array("b1-cars","e1-eggs","d1-chocolate2"); /// for ($i=0;$i<count($data_1);$i++) { $show="bad"; /// Explode ID $data_1 /// $exp_id=explode("-",$data_1[$i]); /// for ($h=0;$h<count($data_2);$h++) { /// Explode ID $data_2 /// $exp_id2=explode("-",$data_2[$h]); /// if ($exp_id2[0]=="".$exp_id[0]."") { $show="ok"; print "".$data_2[$h]."<br>"; } /// } if ($show=="bad") { print "".$data_1[$i].""; print "<br>"; } /// } ?>

  • PHP Doctrine: filtering data which is already loaded?

    - by ropstah
    I'm new to Doctrine and ActiveRecord. How should I filter a table after it has been loaded? (i suppose this is preferred over sending multiple queries?) Is this 'good' or 'bad'? class UserTable extends Doctrine_Table { function filterByGroup($group) { $ut = new UserTable(); foreach($this as $u) { if($u->group = $group) $ut->add($u); } return $ut; } }

  • Events + Adapter Pattern

    - by Stretto
    I have an adapter pattern on a generic class that essentially adapts between types: class A<T> { event EventHandler e; } class Aadapter<T1, T2> : A<T1> { A<T2> a; Aadapter(A<T2> _a) { a = _a; } } The problem is that A contains an event. I effectively want all event handlers assigned to Adapter to fall through to a. It would be awesome if I could assign the a's event handler to adapter's event handler but this is impossible? The idea here is that A is almost really just A but we need a way to adapt the them. Because of the way event's work I can't how to efficiently do it except manually add two event handlers and when they are called they "relay" the to the other event. This isn't pretty though and it would seem much nicer if I could have something like class A<T> { event EventHandler e; } class Aadapter<T1, T2> : A<T1> { event *e; A<T2> a; Aadapter(A<T2> _a) { a = _a; e = a.e; } } in a sense we have a pointer to the event that we can assign a2's event to. I doubt there is any simple way but maybe someone has some idea to make it work. (BTW, I realize this is possible with virtual events but I'd like to avoid this if at all possible)

  • Detect non-closed connections to SQL

    - by JoeJoe
    I've inherited a very large project in ASP.net, SQL 2005 and have found where some SQL connections are not closed - which is bad. Without going thru every line of code, is there a way to detect if connections are not being closed? Performance counter? as a follow up - how does SQL reclaim unclosed connections. I'm using non-pooled connectionstring.

  • Creating a floating button

    - by Robert Smith
    Hey all, I'm working on a Firefox extension and am out of ideas on how to implement a floating button. I need a button that is overlayed on my page that I can show/hide and dynamically position just about anywhere on my page. I thought I could do something like a fancy CSS tool-tip except replace it with button functionality, but that idea failed because I couldn't pull my example apart well enough to understand what all I need to include, need to change, etc. I've thought about using jQuery(though wouldn't mind avoiding, unless it makes this painfully easy) but will be looking more into that as a possibility now. If anyone can offer a tutorial link, ideas, sample code, anything to help get me moving in the right direction I will greatly appreciate it! Thanks! Edit: Clarification I'm not entirely sure how to actually create the overlayed button. I tried to create a a floating div with some text in it, and nothing showed up, but I got no errors, which means I'm doing something wrong, but I have no idea what that is. http://www.fijiwebdesign.com/blog/css-tooltips-floating-html-elements.html If you take a look at that webpage you see that there is that floating "feedback" button, I would like to create something similar, only it wouldn't be anchored to the sides, but I could position it over text, etc. #floatingBtn { position: absolute; z-index: 10000; top: 50%; left: 50%; } Thats the CSS I used to try and float my div. I don't know if I'm creating the div in the wrong place or... I thought if I could get a floating div with some text, I could turn that into my button.

  • [PHP/MySQL] How to create text diff web app

    - by Adam Kiss
    Hello, idea I would like to create a little app for myself to store ideas (the thing is - I want it to do MY WAY) database I'm thinking going simple: id - unique id of revision in database text_id - identification number of text rev_id - number of revision flags - various purposes - expl. later title - self expl. desc - description text - self expl . flags - if I (i.e.) add flag rb;65, instead of storing whole text, I just said, that whenever I ask for latest revision, I go again in DB and check revision 65 Question: Is this setup the best? Is it better to store the diff, or whole text (i know, place is cheap...)? Does that revision flag make sense (wouldn't it be better to just copy text - more disk space, but less db and php processing. php I'm thinking, that I'll go with PEAR here. Although main point is to open-edit-save, possiblity to view revisions can't be that hard to program and can be life-saver in certain situations (good ideas got deleted, saving wrong version, etc...). However, I've never used PEAR in a long-time or full-project relationship, however, brief encounters in my previous experience left rather bad feeling - as I remember, it was too difficult to implement, slow and humongous to play with, so I don't know, if there's anything better. why? Although there are bazillions of various time/project/idea management tools, everything lacks something for me, whether it's sharing with users, syncing on more PCs, time-tracking, project management... And I believe, that this text diff webapp will be for internal use with various different tools later. So if you know any good and nice-UI-having project management app with support for text-heavy usage, just let me know, so I'll save my time for something better than redesigning the weel.

  • Is there better documentation then the original OpenAL docs? [closed]

    - by mystify
    OpenAL is such a huge thing, and the documentation doesn't tell what values are acceptable for properties. That's really bad. I'm using the document: "OpenAL_Programmers_Guide.pdf" Whenever I look up a property I'm left in the dark what value might be ok. For example, take AL_PITCH. What value? Maybe someone wrote a better one? Or is there something like a wiki place with more details?

  • When asked "How do I make a website?" how do you answer?

    - by Luke CK
    A (non-technical) friend of mine has asked me how to make a website. I get this question all the time. After a few questions I found out that she has an idea that could turn into a commercial site. I described three options to her: a) Get a book/enroll in a class/follow some online tutorials and learn how to do it. She's pretty smart and her personality seems like a good match for this sort of thing so I'm sure she could learn but she doesn't have a lot of time spare. Maybe if she started with one of those WYSIWYG editors at first? I stressed that this would take a longer than a couple of weekends of playing around. b) Hire someone to build it. Ranges from ultra cheap to ultra expensive, crappy to good and everything in between. I didn't mention sites like Rentacoder because she hasn't worked on a project like this before and doesn't know what to ask for. At this stage she'd likely ask for a Youtube-MySpace-Google for a few hundred bucks because she doesn't yet understand just how much is involved. c) Find someone technical and partner up with them. I explained that this can either work really well or be a disaster because she'd have to give up some of her ownership of the idea. How do you respond in these situations?

  • Is there a way to deserialize an object into "$this"?

    - by Andreas Bonini
    I'm writing a class to handle a memcached object. The idea was to create abstract class Cachable and all the cachable objects (such as User, Post, etc) would be subclasses of said class. The class offers some method such as Load() which calls the abstract function LoadFromDB() if the object is not cached, functions to refresh/invalidate the cache, etc. The main problem is in Load(); I wanted to do something similar: protected function Load($id) { $this->memcacheId = $id; $this->Connect(); $cached = $this->memcache->get(get_class($this) . ':' . $id); if($cached === false) { $this->SetLoaded(LoadFromDB($id)); UpdateCache(); } else { $this = $cached; $this->SetLoaded(true); } } Unfortunately I need $this to become $cached (the cached object); is there any way to do that? Was the "every cachable object derives from the cachable class" a bad design idea?

  • Do you think its user unfriendly to show error message in tooltips ?

    - by msfanboy
    Hello, when my user enters data validated as wrong a red circle with a white exclamation mark is shown in the right part of the textbox with the wrong data. The error message is only shown when the user hovers the textbox with wrong data. Do you think that is a bad User experience ? I could show the red error message text to the right side of the textboxes if there would still be space...

  • What are all the concurrent things [data structure, algorithm, locking mechanism] missing in .Net 3.

    - by user49767
    First time I am bit disappointed in StackOverflow cause my http://stackoverflow.com/questions/2571727/c-concurrency-vs-java-concurrency-which-is-neatly-designed-which-is-better question was closed. My intension was just trying to gather knowledge from programming guru's who worked in both the programming technologies. Rather closing this question, please help me by discussing what is good, bad, and ugly in multi-threading part in both the platforms. It is also welcome, if someone would like to compare with .Net 4.0 with JDK 6 (or JDK 7)

    - by Chilln

  • Emacs: Often switching between Emacs and my IDE's editor, how can I 'synch' the file?

    - by WizardOfOdds
    I very often need to do some Emacs magic on some files and I need to go back and forth my IDE (IntelliJ IDEA) and Emacs. When a change is made under Emacs (and after I've saved the file) and I go back to IntelliJ the change appears immediately (if I recall correctly I configured IntelliJ to "always reload file when a modification is detected on disk" or something like that). I don't even need to reload: as soon as IntelliJ IDEA gains focus, it instantly reloads the file (and I hence have immediately access to the modifications I made from Emacs). So far, so very good. However "the other way round", it doesn't work yet. Can I configure Emacs so that everytime a file is changed on disk it reloads it? Or make Emacs, everytime it "gains focus", verify if any file currently opened has been modified on disk? I know I can start modifying the buffer under Emacs and it shall instantly warn that it has been modified, but I'd rather have it do it immediately (for example if I used my IDE to do some big change, when I come back to Emacs what I see may not be at all anymore what the file contains and it's a bit weird).

  • get metadata from jpg, dng and arw raw files

    - by Daniel
    I was wondering if anyone new how to get access the metadata (the date in particular) from jpg, arw and dng files. I've recently lost the folder structure after a merge operation gone-bad and would like to rename the recovered files according to the metadata. I'm planning on creating a little C++ app to dig into each file and get the metadata. any input is appreciated. ( alternatively, if you know of an app that already does this I'd like to know :)

  • Permission Denied error in IE when closing popups

    - by Kenia
    Hi everyone! I have a simple web testing application which is supposed to open and close several popups by itself (without user interaction). For this purpose i have a javascript function to access the variable where the popup reference is stored and close it if it´s not null, fairly simple. However I get random errors in IE (in FF it works as expected, all popups are closed correctly) like Message: No such interface supported Line: 86 Char: 3 Code: 0 URI: http://10.10.0.61:10000/savmailer/adm/tests/common_tests_code.js and Message: Permission denied Line: 86 Char: 3 Code: 0 URI: http://10.10.0.61:10000/savmailer/adm/tests/common_tests_code.js The line 86 references exactly the point at which I do popup.close(); in the following function function closePopupWindow(popup){ if (popup != null) { popup.close(); popup = null; } } I have googled and it seems this permission denied error is quite common to come through among IE developers, however there´s no clear solution for it, it´s just a matter of changing the code slightly "to please" IE, so to speak. However i have no idea how to change mine since it´s just 3 lines! Tried also to change the security browser settings by adding my domain to the trusted zone, but nothing, doesn't help either. If anyone has any helpful idea or notices something i might be forgetting, please, reply to this! Thanks in advance, Kenia
