• How to plan my web based project before starting code ?

  - by Arsheep

  Me and my friend started working together as partners , we have decided to make Kick-as* website after website. We have the ideas written down like 100's of them (yes we are choosing best and easy among them first). My friend does the layout design and arranging things , and my part is coding and server management. The little problem i am facing is lack of experience in planing a project. What i do is, I just start the code straight away and along with code I make DB, like when i need a table i make it. I know this is very bad approach for a medium sized project. Here at stackoverflow i saw lots of experienced coders. Need to learn a lot from you guys :) . So can you plese help me on how to plan a project and what coding standard/structure/frameworks to be used (I do PHP code). Thanks in advance.

• 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)

• Safe executing shell scripts; escaping vars before execution.

  - by Kirzilla

  Hello, Let's imagine that we have a simple php script that should get ssh_host, ssh_username, ssh_port from $_GET array and try to connect using this parameters to SSH. $port = escapeshellcmd($_GET['ssh_port']); $host = escapeshellcmd($_GET['ssh_host']); $username = escapeshellcmd($_GET['ssh_username']); $answer = shell_exec("ssh -p " . $port . " " . $user . "@" . $host); Is escapeshellcmd() enough or I need something more tricky? Or maybe I should use escapeshellarg() in this example? Thank you.

• How to customize BsGridView to show links instead of BsButtonColumn?

  Given the code below, I need to customize the third column to show two links instead of that BsButtonColumn. I didn't find any related documentation to get the answer. <?php $this->widget( 'bootstrap.widgets.BsGridView', array( 'id' => 'activity-translation-grid', 'dataProvider' => $model->search(), 'filter' => $model, 'columns' => array( 'id', 'name', array( 'class' => 'BsButtonColumn', ), ), ) ); ?>

• Jetty 6: Unknown Error 99

  - by Silvio Donnini

  The system I'm developing is comprised of a jetty server (v6.1.2rc4) and a php frontend that sends http requests to jetty via curl_exec. The server and the client are on the same machine. The requests I send can be both POSTs and GETs, I get the same error for either which is: Failed to connect to 127.0.0.1: Unknown error 99 This is rather cryptic. It seems that after the first problematic request, some of the following (unrelated) requests also get corrupted. It looks like jetty is simply refusing the connection, but I can't read more than that into the error message. I thought it was a problem with the server's configuration, so I tried changing jetty's maxIdleTimeMs, but without success. Any idea about what to do is welcome thanks, Silvio

• PayPal testing without using Sandbox

  - by Webbo

  I am developing a website in PHP that accepts PayPal payments. It uses the IPN from PayPal and has a custom payment template etc etc. It all works great through the Sandbox server but when it comes to showing my client, I don't want to have to tell them to login to/create a Sandbox account, create a buyer account and make a payment - he hasn't got time for that and probably won't be able to do it. Therefore, my question is - is there any simple way that I can show my client the PayPal integration in "test mode" without him using the sandbox? I realise that I can set the transaction value to 0.01 and just test on the live PayPal server but that isn't an ideal solution. Cheers! Edit: Just to better explain what I mean, this is what my client sees when he first goes to checkout; As you can see, he has to login to his Sandbox account before then purchasing the item using the buyer email that he sets up. It's just confusing and totally non user-friendly.

• Automatically pulling on remote server with Git push?

  - by Vernon

  Here's what I'm trying to do: I have a GitHub repository, a portion of which I'd like to make web viewable. Right now I've cloned the repository on my own server and it works well, but in order to keep it up to date, I have to manually login and pull the latest changes. I'm not sure if this is the best idea (or the best approach), but I'd like the remote server to automatically pull whenever someone pushes to repository. GitHub makes it easy enough to run a script when someone pushes, but I'm not sure how to pull once someone does that. I was using PHP for simplicity, but just doing something like git pull naturally doesn't work because of permissions. Is this a bad idea or is there another way of achieving what I want to do? This seems like a common set up, but I wasn't sure. Thanks.

• 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

• 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(); }

• 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%

Any thoughts?

• Returned JSON is seemingly mixed up when using jQuery Ajax

  - by Niall Paterson

  I've a php script that has the following line: echo json_encode(array('success'=>'true','userid'=>$userid, 'data' => $array)); It returns the following: { "success": "true", "userid": "1", "data": [ { "id": "1", "name": "Trigger", "image": "", "subtitle": "", "description": "", "range1": null, "range2": null, "range3": null }, { "id": "2", "name": "DWS", "image": "", "subtitle": "", "description": "", "range1": null, "range2": null, "range3": null } ] } But when I call a jQuery ajax as below: $.ajax({ type: 'POST', url: 'url', crossDomain: true, data: {name: name}, success: function(success, userid, data) { if (success = true) { document.write(userid); document.write(success); } } }); The userid is 'success'. The actual success one works, its true. Is this malformed data being returned? Or is it simply my code? Thanks in advance, Niall

• how to have defined connection within function for pdo communication with DB

  - by Scarface

  hey guys I just started trying to convert my query structure to PDO and I have come across a weird problem. When I call a pdo query connection within a function and the connection is included outside the function, the connection becomes undefined. Anyone know what I am doing wrong here? I was just playing with it, my example is below. include("includes/connection.php"); function query(){ $user='user'; $id='100'; $sql = 'SELECT * FROM users'; $stmt = $conn->prepare($sql); $result=$stmt->execute(array($user, $id)); // now iterate over the result as if we obtained // the $stmt in a call to PDO::query() while($r = $stmt->fetch(PDO::FETCH_ASSOC)) { echo "$r[username] $r[id] \n"; } } query();

• 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?

• 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.
