• Task management algorithm in C#

• At what level should security be implemented in a social network web application ?

  - by Rajkumar Gupta

  I am developing a social web application in php/mysql, I would like to hear your advice about what would be a better way to implement security. I am planning something like this:- At the presentation level, I restricting the user to see only those items/content he is eligible to see with the rights he is eligible & at the database level, whenever my data is read/ written or updated I verify that the person has rights to such interactions with that part of data. So for each action there is 2 layers of security one at the view level & another at the database level. Would double checking be much overhead ? ofcourse this handles only with the internal security issues ..

• Is is better to store serialized data or raw html in mysql?

  - by Yegor

  I de-normalized my database, since the application was crawling otherwise, and Im storing a list of categories for each item in the DB as a raw html version, and simply echoing it out in my design. Each category is actually a link, which is include a tag. Naturally, this is abit of a pain, especially if I want to change the look of how the category links are displayed, since I gotta update all the old cached entries. What if I were to store this data as a serialized array instead, and simply unserialize it, and then apply formatting to it in php. Would there be a significant performance decrease over simply echoing out the raw html?

• Should I use Drupal or Kohana-type framework for a web "application"

  - by Andres

  The debate is that I need a PHP Framework/Drupal with the flexibility to add custom features to a potentially large application (web and with an api). However, with a framework, like Kohana, I see myself tackling and re-inventing the wheel with the simple stuff like account management and cms stuff. Account management and quick data collection, like fast form creation, are tedious in Kohana but appear incredible simple in Drupal. On the other hand, based on my limited Drupal experience, I doubt building rapid custom "features" and allowing users to create "groups" and to manage their own roles within those groups is something Drupal can easily accomplish. To simplify, is Drupal capable of true Web Applications; where the application is a service and provides custom results to each user? Can it provide a dashboard-like interface for users to change their settings or preferences? Can it aggregate data from particular users to provide better results/info to others? If so, please point me to some knowledge :-)

• How to connect to the database in Magento?

  - by Click Upvote

  I'm trying to build a simple Magento Module that needs to connect to the database at the start of each page request. All tables need to be accessible to it. I've been pulling my hair out trying to understand how to do it. The best I could figure out was that I need to set this in the config.xml file of my module, but exactly what that command is/how it may be used, i haven't been able to figure out. Can someone please guide me or show me how to accomplish this? If not, would it be too bad a practice to include a custom config.php file which connects to the database manually?

• Postgres pg_dump dumps database in a different order every time

  - by behrk2

  Hello, I am writing a PHP script (which also uses linux bash commands) which will run through test cases by doing the following: I am using a PostgreSQL database (8.4.2)... 1.) Create a DB 2.) Modify the DB 3.) Store a database dump of the DB (pg_dump) 4.) Do regression testing by doing steps 1.) and 2.), and then take another database dump and compare it (diff) with the original database dump from step number 3.) However, I am finding that pg_dump will not always dump the database in the same way. It will dump things in a different order every time. Therefore, when I do a diff on the two database dumps, the comparison will result in the two files being different, when they are actually the same, just in a different order. Is there a different way I can go about doing the pg_dump? Thanks!

• reply to a comment via email and directly post it on the website commenting system

  - by Gaurav Sharma

  Hello Everybody, I have developed a website using PHP and MYSQL. The website has a commenting system through which registered users of the website can post comments on the feedback posted by different users. When a comment is posted for a feedback an email is sent to the user who posted that feedback notifying him of new comments on his feedback. Now what I want is that a feedback owner should be able to post a new comment in response to that comment by simply replying to the email that has been sent by the website. I hope I was able to explain my query properly. If it needs any improvement in explanation, I would be glad to know and make changes accordingly Thanks

• How to extracting individual dimensions from $node->content['dimensions'] in Drupal's Ubercart?

  - by Walden

  On my Ubercart node-product.tpl.php page, I am trying to extract the individual product dimensions (height, weight, length) from the more generic: print $node->content['dimensions'] ['#value']; which returns "Dimensions: 72in. × 42in. × 30in." Using var_dump(get_defined_vars()); I'm able to see that the dimensions are being outputted independently, but can't seem to get them to print. on the page. What is the proper way to call the dimensions individually?

• Display archive posts in Wordpress

  - by missmonkee

  I am looking to display archives pages as a normal posts page... So, a posts page with a secondary navigation showing: Latest posts / Last month / Last year / Older On each of those pages, I would like to display a summary of each post just like the standard latest news page. When you click through you get to the full post. For each of menu items I have created seperate page templates such as archives_month.php, Then in the template instead of using For the LAST MONTH page. But I now cannot use this for LAST YEAR and OLDER posts. Can anyone help me? I've looked into a number of different ways to do it but on some blogs it's not clear and most people just retrieve a list of archives rather than displaying the posts. Thanks in advance. Mel

• Sanitize a string from ascii art

  - by Toto

  I need to sanitize article titles when (creative) users try to "attract attention" with some bad "ascii art". Exemples: Buy my product !!!!!!!!!!!!!!!!!!!!!!!! Buy my product !? !? !? !? !? !? Buy my product !!!!!!!!!.......!!!!!!!! Buy my product <----------- Some acceptable solution would be to reduce the repetition of non-alphanum to 2. So I would get: Buy my product !! Buy my product !? !? Buy my product !!..!! Buy my product <-- This solution did not work that well: preg_replace('/(\W{2,})(?=\1+)/', '', $title) Any idea how to do it in PHP with regex? Other better solution is also welcomed (I cannot strip all the non-alphanum characters as they can make sense).

• Sign Up/Login system for multi-domain/multi-server

  - by David

  I'm thinking about a good solution for implementing a sign up/login system that works across different domains and servers. A working example is Olx (you can register in one domain, and your login will work in the rest of domains). The scenario is that every domain (one per country) has its own database. And there will be 2 servers (for example), each one will have the 50% of the domains (and so the 50% of databases). What would you suggest to start with? Database: MySQL 5.1 Server-side language: PHP 5.3 (I will be using Symfony 1.4, so if someone has some suggestion for this framework, it will be interesting too, although it is optional)

• PDO::ATTR_EMULATE_PREPARES => false

  - by user264058

  I'm new to php and PDO ,so i read this response to a similar post- Does PDO really not use prepared statements with mysql? Yes, by default (at least with version I tested) but native mode can be turned on manually. If not, can it be forced to do so By employing PDO::ATTR_EMULATE_PREPARES setting, the name is pretty self-explanatory. $dbh-setAttribute( PDO::ATTR_EMULATE_PREPARES, false ); should you do that? That's hardest question of them all. Well, I'd say - yes, you should. If you choose PDO as your db driver, there is no point in using it in the emulation mode. by YOUR COMMON SENSE Aren't prepared statements secure from SQL injection, why change if from 'true'-false?? what is native mode??

• How to iterate over an array of objects without foreach and ArrayAccess

  - by kenny99

  Hi, I'm having to develop a site on PHP 5.1.6 and I've just come across a bug in my site which isn't happening on 5.2+. When using foreach() to iterate over an object, I get the following error: "Fatal error: Objects used as arrays in post/pre increment/decrement must return values by reference..." Does anyone know how to convert the following foreach loop to a construct which will work with 5.1.6? Thanks in advance! foreach ($post['commercial_brands'] as $brand) { $comm_food = new Commercial_food_Model; $comm_food->brand = $brand; $comm_food->feeding_type_id = $f_type->id; $comm_food->save(); }

  Hi, I'm new to PHP oop stuff. I'm trying to create class database and call other classes from it. Am I doing it the right way? class database: class database extends mysqli { private $classes = array(); public function __construct() { parent::__construct('localhost', 'root', 'password', 'database'); if (mysqli_connect_error()) { $this->error(mysqli_connect_errno(), mysqli_connect_error()); } } public function __call($class, $args) { if (!isset($this->classes[$class])) { $class = 'db_'.$class; $this->classes[$class] = new $class(); } return $this->classes[$class]; } private function error($eNo, $eMsg) { die ('MySQL error: ('.$eNo.': '.$eMsg); } } class db_users: class db_users extends database { public function test() { echo 'foo'; } } and how I'm using it $db = new database(); $db->users()->test(); Is it the right way or should it be done another way?

• search for a winner, returning their rank

  - by incrediman

  Earlier I asked this question, which basically asked how to list 10 winners in a table with many winners, according to their points. This was answered. Now I'm looking to search for a given winner X in the table, and find out what position he is in, when the table is ordered by points. For example, if this is the table: Winners: NAME:____|__POINTS: Winner1 | 1241 Winner2 | 1199 Sally | 1000 Winner4 | 900 Winner5 | 889 Winner6 | 700 Winner7 | 667 Jacob | 623 Winner9 | 622 Winner10 | 605 Winner11 | 600 Winner12 | 586 Thomas | 455 Pamela | 434 Winner15 | 411 Winner16 | 410 These are possible inputs and outputs for what I want to do: Query: "Sally", "Winner12", "Pamela", "Jacob" Output: 3 12 14 623 How can I do this? Is it possible, using only a MySQL statement? Or do I need PHP as well? This is the kind of thing I want: WHEREIS FROM Winners WHERE Name='Sally' LIMIT 1 Ideas?

• How to Practically Split Values from CSV File into MySQL Database

  - by Ryan

  Let's suppose I have the following line in a CSV file (I removed the header row in this example): "500,000",2,50,2,90000 I have a PHP script read the CSV file, break the file into individual lines, and store each line in an array called $linearray. Then, I use a foreach loop to look at each line individually. Within the foreach loop, I break the line into separate variables using the following function: $line = str_replace("'","\'",$line); From here, I insert the values into separate columns within a MySQL database. The script works. The values are inserted into a database, but I run into a problem. I want: "500,000" | 2 | 50 | 2 | 90000 But I get this: "500 | 000" | 2 | 50 | 2 | 90000 The script isn't smart enough to understand it should skip commas within quotation marks. Do you know how I can alter my script to make sure I get the output I'm looking for? Thanks.

• How to detect an 'image area' percentage inside an image?

  - by DaNieL

  Mhh, kinda hard to explain with my poor english ;) So, lets say I have an image, doesnt matter what kind of (gif, jpg, png) with 200x200 pixel size (total area 40000 pixels) This image have a background, that can be trasparent, or every color (but i know the background-color in advance). Lets say that in the middle of this image, there is a picture (for keep the example simple lets suppose is a square drawn), of 100x100 pixels (total area 10000 pixels). I need to know the area percentage that the small square fill inside the image. So, in i know the full image size and the background-color, there is a way in php/python to scan the image and retrieve that (in short, counting the pixel that are different from the given background)? In the above example, the result should be 25%

• MySQL or SQL Server

  - by user203708

  I'm creating an application that I want to run on either MySQL or SQL Server (not both at the same time) I've created two PHP classes DatabaseMySQL and DatabaseSQLSVR and I'd like my application to know which database class to use based on a constant set up at install. define(DB_TYPE, "mysql"); // or "sqlsrv" I'm trying to think of the best way to handle this. My thought is to do an "if else" wherever I instantiate the database: $db = (DB_TYPE == "mysql") ? new DatabaseMySQL : new DatabaseSQLSVR; I know there has to be a better way of doing this though. Suppose I want to add a third database type later; I'll have to go and redo all my code. Yuk!! Any help would be much appreciated. Thank

• PDOStatement::bindParam() not setting AI value from MySQL insert?

  - by Alan

  I have a simple insert statement using PDO php class. $statement = $db->prepare('INSERT INTO demographics (id,location_id,male,ethnicity_id,birthyear) VALUES (:id,:location_id,:male,:ethnicity_id,:birthyear)'); $statement->bindParam(':id',$demo->id,PDO::PARAM_INT,4); $statement->bindParam(':location_id', $demo->locationid,PDO::PARAM_INT); $statement->bindParam(':male',$demo->male,PDO::PARAM_BOOL); $statement->bindParam(':ethnicity_id',$demo->ethnicityid,PDO::PARAM_INT); $statement->bindParam(':birthyear',$demo->birthyear,PDO::PARAM_INT); $statement->execute(); print_r($demo); Even though the statement executes correctly (row is correctly written), $demo-id is null. Any thoughts?

• Online Image Slideshow Question. File Access Problems.

  - by msandbot

  Hi, I have a flash .swf file that I embed on my webpage. On my server I have the .swf file and multiple image folders. I would like to load every file in one of those folders into the flash slideshow. How should I go about doing this? I tried used Air but it doesn't work on my system as an application so I doubt it will work online. Eventually I plan on making a menu where you can select different folders to display and since they are of different sizes, a foreach loop would be optimal. Keeping a txt file with the number of images is also possible if theres a way to read that in, but I would prefer the more dynamic approach. I am working towards using php for the website if that helps find a solution. Thanks, -Mike Also my slideshow works great online currently but i have to hardcode in the number of files.

• Dynamically created image doesn't show when <img>'s src is refreshed to point to it

  - by Obay

  Hello, I have a javascript function generateGraph() { ... jQuery.get('chart.php?month='+month+'&year='+year); document.getElementById('graph').src = 'charts/'+month+'_'+year+'.png'; ... } which is called onChange. It basically creates, if not exists, or refreshes if already exists, a PNG image (using the first line above) and supposedly displays the generated image (using the second line above). The first line works, but the second one doesn't. Meaning, the image is generated, but the second line can't display the image, unless the page is reloaded, or if the image being referred to already existed before the page was loaded (meaning the 1st line just "refreshed" the image) Any ideas as to why this is and how to fix it? Thanks much for your help in advance!

• Why doesn't MySQL support millisecond precision?

  - by Byron Whitlock

  So I just found the most frustrating bug ever in MySQL. Apparently the TIMESTAMP field, and supporting functions do not support any greater precision than seconds!? So I am using PHP and Doctrine, and I really need those microseconds (I am using the actAs: [Timestampable] property). I found a that I can use a BIGINT field to store the values. But will doctrine add the milliseconds? I think it just assigns NOW() to the field. I am also worried the date manipulation functions (in SQL) sprinkled through the code will break. I also saw something about compiling a UDF extension. This is not an acceptable workaround because I or a future maintainer will upgrade and poof, change gone. Has anyone found a suitable workaround?
