  • Should an object be fully complete before injected as a dependency?

    - by Hans
    This is an extension of this question: http://stackoverflow.com/questions/3027082/understanding-how-to-inject-object-dependencies. Since it is a bit different, I wanted to separate them, to make it, hopefully, easier to answer. Also, this is not a real system, just a simplified example that I thought we'd all be familiar with. TIA. : DB threads: thread_id, thread_name, etc posts: post_id, thread_id, post_name, post_contents, post_date, post_user_id, etc Overview Basically I'm looking at the most maintainable way to load $post_id and have it cascade and load the other things I want to know about and I'm trying to keep the controller skinny. BUT: I'm ending up with too many dependencies to inject I'm passing in initialized but empty objects I want to limit how many parameters I am passing around I could inject $post(-many) into $thread(one<-), but on that page I'm not looking at a thread, I'm looking at a post I could combine/inject them into a new object Detail If I am injecting an object into another, is it best to have it fully created first? I'm trying to limit how many parameters I have to pass in to a page, but I end up with a circle. // 1, empty object injected via constructor $thread = new Thread; $post = new Post($thread); // $thread is just an empty object $post->load($post_id); // I could now do something like $post->get('thread_id') to get everything I want in $post // 2, complete object injected via constructor $thread = new Thread; $thread->load($thread_id); // this page would have to have passed in a $thread_id, too $post = new Post($thread); // thread is a complete object, with the data I need, like thread name $post->load($post_id); // 3, inject $post into $thread, but this makes less sense to me, since I'm looking at a post page, not a thread page $post = new Post(); $post->load($post_id); $thread = new Thread($post); $thread->load(); // would load based on the $post->get('post_id') and combine. Now I have all the data I want, but it's non-intuitive to be heirarchially Thread->Post instead of Post-with-thread-info // Or, I could inject $post into $thread, but if I'm on a post page, // having an object with a top level of Thread instead of // Post-which-contains-thread-info, makes less sense to me. // to go with example 1 class post { public function __construct(&$thread) { $this->thread=$thread; } public function load($id) { // ... here I would load all the post data based on $id // now include the thread data $this->thread->load($this->get('thread_id')); return $this; } } // I don't want to do $thread = new Thread; $post = new Post; $post->load($post_id); $thread->load($post->get('post_id')); Or, I could create a new object and inject both $post and $thread into it, but then I have object with an increasing number of dependencies.

  • Voting Script, Possiblity of Simplifying Database Queries

    - by Sev
    I have a voting script which stores the post_id and the user_id in a table, to determine whether a particular user has already voted on a post and disallow them in the future. To do that, I am doing the following 3 queries. SELECT user_id, post_id from votes_table where postid=? AND user_id=? If that returns no rows, then: UPDATE post_table set votecount = votecount-1 where post_id = ? Then SELECT votecount from post where post_id=? To display the new votecount on the web page Any better way to do this? 3 queries are seriously slowing down the user's voting experience

  • code doesnot delete specific extra files but deletes all, also no recursion for directory, help me t

    - by OM The Eternity
    I have to compare two folder structure and with reference of source folder I want to delete all the files/folders present in other destination folder which do not exist in reference source folder, how could i do this? $original = scan_dir_recursive('/var/www/html/copy2'); $mirror = scan_dir_recursive('/var/www/html/copy1'); function scan_dir_recursive($dir) { $all_paths = array(); $new_paths = scandir($dir); foreach ($new_paths as $path) { if ($path == '.' || $path == '..') { continue; } $path = $dir . DIRECTORY_SEPARATOR . $path; if (is_dir($path)) { $all_paths = array_merge($all_paths, scan_dir_recursive($path)); } else { $all_paths[] = $path; } } return $all_paths; } foreach($mirror as $mirr) { if($mirr != '.' && $mirr != '..') { if(!in_array($mirr, $original)) { unlink($mirr); // delete the file } } } The above code shows what i did.. Here My copy1 folder contains extra files than copy2 folders hence i need these extra files to be deleted. Below given output is are arrays of original Mirror and of difference of both.. Original Array ( [0] => /var/www/html/copy2/Copy (5) of New Text Document.txt [1] => /var/www/html/copy2/Copy of New Text Document.txt ) Mirror Array ( [0] => /var/www/html/copy1/Copy (2) of New Text Document.txt [1] => /var/www/html/copy1/Copy (3) of New Text Document.txt [2] => /var/www/html/copy1/Copy (5) of New Text Document.txt ) Difference Array ( [0] => /var/www/html/copy1/Copy (2) of New Text Document.txt [1] => /var/www/html/copy1/Copy (3) of New Text Document.txt [2] => /var/www/html/copy1/Copy (5) of New Text Document.txt ) when i iterate a loop to delete on difference array all files has to be deleted as per displayed output.. how can i rectify this.. the loop for deletion is given below. $dirs_to_delete = array(); foreach ($diff_path as $path) { if (is_dir($path)) { $dirs_to_delete[] = $path; } else { unlink($path); } } while ($dir = array_pop($dirs_to_delete)) { rmdir($dir); }

  • count specific values in a multidimensional array

Thank You.

  • Contact page MVC workflow

    - by alex
    All my previous projects have had this workflow on Contact pages User submits form Controller gets $_POST details Controller validates details (and sets error messages if necessary) Controller sends email Controller redirects to thanks page Is this the standard workflow? I used to validate everything in controllers, and then did some more reading and they recommended against it. Therefore, should I send the $_POST details to a helper type object and let it do all the work (validation/sending)?

  • benefit os having a factory for object creation?

    - by ajsie
    im trying to understand the factory design pattern. i dont understand why it's good to have a middleman between the client and the product (object that the client wants). example with no factory: $mac = new Mac(); example with a factory: $appleStore = new AppleStore(); $mac = $appleStore->getProduct('mac'); how does the factory pattern decouple the client from the product? could someone give an example of a future code change that will impact on example 1 negative, but positive in example 2 so i understand the importance of decoupling? thanks

  • Memcached - how to deal with adding/deploying servers

    - by Industrial
    Hi everybody, How do you handle replacing/adding/removing memcached nodes in your production applications? I will have a number of applications that are cloned and customized due to each customers need running on one and same webserver, so i'll guess that there will be a day when some of the nodes will be changed. Here's how memcached is populated by normal: $m = new Memcached(); $servers = array( array('mem1.domain.com', 11211, 33), array('mem2.domain.com', 11211, 67) ); $m->addServers($servers); My initial idea, is to make the $servers array to be populated from the database, also cached, but file-based, done once a day or something, with the option to force an update on next run of the function that holds the $addservers call. However, I am guessing that this might add some additional overhead since disks are quite slow storage... What do you think?

  • preg_match_all confusing failing

    - by James
    $string = (string) file_get_contents($_FILES['file']['tmp_name']); echo $string; preg_match_all("/[\._a-zA-Z0-9-]+@[\._a-zA-Z0-9-]+/i", $string, $matches); print_r($matches); I am parsing text/csv files and grabbing email addresses from uploaded files. When parsing a Google Contact file I exported it weirdly fails. But when I simply copy the string that is echo'd and paste that instead of the file_get_contents result, it parses and works. Any idea why it is refusing to take the file_get_contents string, but if I paste in the raw data myself, it works?

  • CodeIgniter - the right way to create "block" elements on web page

    - by kikkoman90
    Hello. I've been searching for a solutions for this problem a while but haven't seen any "valid mvc" solution for this. I hope I can explain my problem clearly enough for you guys. I need to create a dynamic block of HTML on my website. (eg. a block containing user's latest blog comments). I have a template view file (a file containing header, content container and a footer) where I need to add some content AND this block element. The problem is that I don't want to duplicate this block code on every controller. It just feels stupid and I'm sure there's a better way to do this than just duplicating same stuff all over again on all the controller files? I can add view inside another view just fine, but what bugs me is how to actually generate that dynamic content to this block's view-file. I can't call controller from view file, controller from controller filem or model from view file because what I understand that just isn't the "mvc" way? Anyone got any tricks or tips for this?
