• Uploading images to a post like on the stackexchange websites [on hold]

  - by Loko

  Stackexchange uses imgur link to show the image to their website, but how do I do this? I am really curious on what ways I can upload an image to a file and show it immediatly again. Like webshops where you can post your products are also uploading images to show them immediatly. What way are there to do this and what is the best / most secure?(I assume how stackexchange does it), but I also have no idea how to do that.

• How do you know when to split an object method into 2 or more other methods?

  - by blacktie24

  Hi, I know this is a very basic question, but I sometimes find myself struggling to figure out when to split a single object method into multiple methods. For example, I am trying to set up an ACL using Zend_Acl and Zend_Auth, as shown in this tutorial: http://devzone.zend.com/article/1665. However, I am wondering if the My_Plugin_Auth::preDispatch() method should invoke calls to a method called authenticate() and a method called authorize(), instead of having everything lumped in under preDispatch(). I was thinking that this would make the code more readable and encapsulate the logic into its smaller parts, but i'm not sure if this is reason enough.

• Repository query conditions, dependencies and DRY

  - by vFragosop

  To keep it simple, let's suppose an application which has Accounts and Users. Each account may have any number of users. There's also 3 consumers of UserRepository: An admin interface which may list all users Public front-end which may list all users An account authenticated API which should only list it's own users Assuming UserRepository is something like this: class UsersRepository extends DatabaseAbstraction { private function query() { return $this->database()->select('users.*'); } public function getAll() { return $this->query()->exec(); } // IMPORTANT: // Tons of other methods for searching, filtering, // joining of other tables, ordering and such... } Keeping in mind the comment above, and the necessity to abstract user querying conditions, How should I handle querying of users filtering by account_id? I can picture three possible roads: 1. Should I create an AccountUsersRepository? class AccountUsersRepository extends UserRepository { public function __construct(Account $account) { $this->account = $account; } private function query() { return parent::query() ->where('account_id', '=', $this->account->id); } } This has the advantage of reducing the duplication of UsersRepository methods, but doesn't quite fit into anything I've read about DDD so far (I'm rookie by the way) 2. Should I put it as a method on AccountsRepository? class AccountsRepository extends DatabaseAbstraction { public function getAccountUsers(Account $account) { return $this->database() ->select('users.*') ->where('account_id', '=', $account->id) ->exec(); } } This requires the duplication of all UserRepository methods and may need another UserQuery layer, that implements those querying logic on chainable way. 3. Should I query UserRepository from within my account entity? class Account extends Entity { public function getUsers() { return UserRepository::findByAccountId($this->id); } } This feels more like an aggregate root for me, but introduces dependency of UserRepository on Account entity, which may violate a few principles. 4. Or am I missing the point completely? Maybe there's an even better solution? Footnotes: Besides permissions being a Service concern, in my understanding, they shouldn't implement SQL query but leave that to repositories since those may not even be SQL driven.

• Image caching when rendering the same images on different pages

  - by HelpNeeder

  I'm told to think about caching of images that will be displayed on the page. The images will be repeated throughout the website on different pages and I'm told to figure out the best way to cache these images. There could be few to dozen of images on single page. Here's few questions: Will browser caching work to display the same images across different web pages? Should I rather store images in stringified form in a memory instead, using JavaScript arrays? Store them on hard drive using 'localStorage'? What would be easiest yet best option for this? Are there any other alternatives? How to force cache? Any other information would be greatly appreciated...

• Request of some opinions about a vertical menu style and some suggestions for the site style [on hold]

  - by AndreaNobili

  I am developing a simple mainly static website using WordPress (because maybe in the future I will add some dynamic content) for a company. The new site have to follow the structure of the old site that requires the presence of a vertical main menu in the left column that contains the link to all the statics pages in the site. This is the old site structure: http://www.saranistri.com/ Now I have installed a new WordPress test site (this is only a test site): http://onofri.org/example/ As you can see in the left columns I have put two main menu vetical widgets that implements a possible choise for the maun menù (the top menù upon the header must be eliminated in the final implementation) I want to know some opinions about: 1) Which of the two version is better? Do you have some additional ideas about the CSS style of this vertical menu? 2) What could I do to give a more professional look to this site? (I know that I have to insert a logo into the header) Tnx Andrea

• Dynamically change page content based on URL parameter?

  - by volume one

  The title of my question seems simple but here is an example of what I want to do: http://www.mayoclinic.com/health/infant-jaundice/DS00107 What happens on that page is whenever you click on a link to go a section (e.g. "Symptoms") in the article on "Infant Jaundice", it provides a URL parameter like this: http://www.mayoclinic.com/health/infant-jaundice/DS00107/DSECTION=symptoms As the DESCTION parameter changes, you get different content on the same page DS00107. The content changes as well as <meta keywords>. Can someone please tell me how this is achieved? I was thinking it was an if/else situation programmed into the page itself to display different properties depending on the URL parameter. Any help or suggestions are very much appreciated and my thanks to you for reading my question.

• How can I make a web browser view my .h file as text?

  - by drewbenn

  I want to post a .h file from a project I'm working on. I set a simple href link to it, like: <p>Click here to download the <a href=project_strings.h>strings file</a>. When I click on it, though, my web browser (Iceweasel 12) gives me a prompt to download the file, instead of just displaying it: Is there any magic I can add to the web page, or as a header to the file (that will still allow it to be included by a .c compiled with gcc), to get the .h file to be displayed in the web browser?

• Learning To Program After 9-5

  - by JoshuaPP

  I'm currently working as an IT Administrator but I'm thinking of making a slight career change into programming. I want to focus my time and effort into learning some web based languages but feel is it achievable when working full time to expect to make much progress after a long days work? I love to read, but this is sometimes a hindrance. I have read on some resources that you will never make much progress unless you quit your 9-5 and dedicated 6 months to getting a fundamental understanding. Any feedback would be great. Sorry if it's in the wrong area, I just signed up from my phone.

• Space in img:s "ALT" attribute good/bad for search engines?

  - by Camran

  I am trying to make it easier for search engines to crawl my website, as it is almost 100% dynamic. I have a couple of transparent images which are actually links to sections of my page. I wonder, if I add an "alt" attribute containing space characters to explain the target, will this improve SE rankings etc? For example: <img src="blabla.png" alt="post new classified"> Or will this just result in errors? Ànd, what should I put in the alt attribute if I can't use space? PS: Another different and short question, will javascript-rich content make a page less important to crawlers? Thanks

• Identifying elements from data feeds generated by affiliate sites

  - by SPI

  I am working with data feeds from affiliate sites. The basic idea is to provide an interface where the user can paste a link to an XML datafeed (these are huge btw, around 60 mb) that would then be streamed, parsed into small chunks, and mined for the required data which would then be stored in the database. The problem is that different affiliate sites have different Schemas for their XML's. It is a little hard mapping the elements in an XML to your database attributes when you don't actually know which element contains what. My Solution: Use XPath to traverse through the first set of parent and it's descendent's, fetch the elements as well as the data and and ask the user to map this data to the attributes in the database by selecting from a set of radio buttons that represent the attributes from the database. This will be done just once for each new Feed, once the system know's what's what it will automatically upload the data from the XML to the database. Does this sound viable? Is there a better solution? I realize this leaves an uncomfortable opening for human error.. Thanks.

• Is there a more efficient way to filter large arrays than preg_match()?

  - by hozza

  I have a log that our web application builds. Each month it contains around 16,000 entries of a string with about the average sentence worth of text. To filter/search through these in our admin panel the script uses preg_match() but this seems to be taking ages and timing out on the 30sec limit. I have isolated that it is indeed the preg_match() that causes the time out. Is there a more efficient way to search through values in a large array for a users input?

• Sharing object between 2 classes

  - by Justin

  I am struggling to wrap my head around being able to share an object between two classes. I want to be able to create only one instance of the object, commonlib in my main class and then have the classes, foo1 and foo2, to be able to mutually share the properties of the commonlib. commonlib is a 3rd party class which has a property Queries that will be added to in each child class of bar. This is why it is vital that only one instance is created. I create two separate queries in foo1 and foo2. This is my setup: abstract class bar{ //common methods } class foo1 extends bar{ //add query to commonlib } class foo2 extends bar{ //add query to commonlib } class main { public $commonlib = new commonlib(); public function start(){ //goal is to share one instance of $this->commonlib between foo1 and foo2 //so that they can both add to the properites of $this->commonlib (global //between the two) //now execute all of the queries after foo1 and foo2 add their query $this->commonlib->RunQueries(); } }

• Is it necessary to memorize codes?

  - by AAA

  I am a new developer, who just got hired at a big company. I don't know how but I guess they are desperate. However, I am well-versed with HTML5/CSS3 though things change and new things are released and I keep up with as much as I can. But this job required me to hand-code Javascript, know Jquery and Ajax. I have been exposed to this a bit but I am not sure if I can hand-code Javascript. My question is, is it necessary to memorize all there is about Javascript or are there a few key things that I should know how to hand-code because looking at javascript code it seems there are lots of lines code! Please point me in the right direction.

• Interface hierarchy design for separate domains

  - by jerzi

  There are businesses and people. People could be liked and businesses could be commented on: class Like class Comment class Person implements iLikeTarget class Business implements iCommentTarget Likes and comments are performed by a user(person) so they are authored: class Like implements iAuthored class Comment implements iAuthored People's like could also be used in their history: class history class Like implements iAuthored, iHistoryTarget Now, a smart developer comes and says each history is attached to a user so history should be authored: interface iHistoryTarget extends iAuthored so it could be removed from class Like: class Person implements iLikeTarget class Business implements iCommentTarget class Like implements iHistoryTarget class Comment implements iAuthored class history interface iHistoryTarget extends iAuthored Here, another smart guy comes with a question: How could I capture the Authored fact in Like and Comment classes? He may knows nothing about history concept in the project. By scalling these kind of functionallities, interfaces may goes to their encapsulated types which cause more type strength, on the other hand explicitness suffered and also code end users will face much pain to process. So here is the question: Should I encapsulate those dependant types to their parent types (interface hierarchies) or not or explicitly repeat each type for every single level of my type system or ...?

• confusion understanding the fluid 2 column navigation layout

  - by Jason Madux

  I'm trying to understand the following cross-browser layout: http://matthewjamestaylor.com/blog/perfect-2-column-left-menu.htm but I'm having some confusion with some of its parts and there isn't enough information on the page or in the css comments to help me. What is the purpose of the .colleft div? Why can't the 2 columns be directly under the .colmask container? Why does the .colleft div have a right 75%? I don't understand its purpose/benefit. Why don't the widths of .col1 and .col2 add up to 100%? How was left:102% calculated for .col1 and left:6% for .col2? The comments for this are not very clear to me. How is it any different from not even specifiying a left/right css property?

• Tunneling through SSH for 1521 port access?

  - by A T

  I am developing locally on my computer, using my own Apache server with PHP configured. My database however is remotely located on an Oracle 11g Database Server. We were also given a separate remote server for hosting our .html and .php files, however only FTP access has been provided there. Development is far too slow waiting for the FTP connection to push. So I decided to develop locally, but still use the remote DB server. Unfortunately that gives me an error. Not sure how—or where—to integrate tunnelling. Do I add something to the oci_connect HOST in my PHP file, or do I encapsulate my whole environment over SSH?

• SSL on multiple directories

  - by Shredder

  I have a website that is http, but has a port set up for https for a specific directory that is for the shopping cart. Now I'd like to use our SSL on a different directory in the same site as well. How can I go about configuring that? I have tried looking into all of the config files as well as the docs and cannot figure it out. I tried setting this in httpd.config as well <VirtualHost 127.0.0.1:[ssl port]> #also tried *:[ssl port] and [actual IP]:[ssl port] ServerAdmin [email protected] DocumentRoot "C:/path/sslNeededDir" ServerName www.example.com </VirtualHost> hoping that it would cause pages in this directory to use ssl port and become https, but that didn't do anything. Any help is greatly appreciated. Update: This finally got migrated over. I'm still looking for a solid answer on this. If anyone could help me, it would be greatly appreciated.

• Websockets VS SSE

  - by user3385828

  Sorry for asking this here, I bet it has been asked plenty of times before but this time it's something specific which I haven't understood anywhere else: Suppose I have a service which requires to seek the database for different data once and in a while. For this I have 2 or 3 SSE, each one with a different retry basetime (20000 miliseconds, 1000 miliseconds...). What I'd like to know is if websockets can handle different "data type" accordingly to the request, for example, could I create one websocket to handle a notification system, a chat system, a group system instead of separated SSEs and treat data differently with javascript? And if so, would it be of higher interest (performance) than actually performing different queries to the server through different SSEs?

• I need to create an employee schedule/appointments program, but I don't know how to set it up

  - by robz228

  I work for a gym. I am the programmer, its just me, nobody else! Gets really frustrating when there's nobody to bounce conceptual ideas off of. I'm getting rid of our archaic paper binder systems for tracking appointments and what not. I've made a lot of things successfully already, now I'm trying to tackle the personal training department. What I want: Trainer information and work schedule Appointment booking that can be done by time slot with all available trainers for that time, or by trainer with all available hours for that trainer What I've tried so far: I started with an 'appointments' database, a 'trainers' database, and a 'schedules' database. This became so complicated trying to fit the schedule in that I scrapped it. Does anyone know know the best way to structure the tables for this and how to sort of make them communicate correctly? I don't need specific code, I just need help understand how to make this thing!

• OOP Structure for web application

  - by Query

  Ok so I have a website in which users complete tasks to earn points. When they earn enough points, they rise in rank. The site from my understanding is very basic and only executes one query or two queries at most a page. There is a user table, a support ticket table, and an orders table. All of these contain a relational row for username. Our class was familiarized with OOP back in highschool with Java but that was for video games and I could grasp the concept on why you would need a class player and class enemy. However I don't understand it's web application. At least not in my situation. I understand the user class might contain stuff like: getUsername getPoints getEmail setEmail addPoints (does this belong here? OR only things the user can manipulate should be here?) etc.. But I'm at a loss with everything else such as user registration. Can you help give me a wire framework that I could wrap my head around? Pointing me to a good eBook would help greatly
