• Execute a method less times possible - PHP

  - by serhio

  I have a site in multiple languages. I have a method that returns me the today currencies in a array. I display that currencies in a table then. // --- en/index.php <?php include_once "../exchangeRates.php"; $currencies = ReadExchangeRates(); // --- fr/index.php <?php include_once "../exchangeRates.php"; $currencies = ReadExchangeRates(); ... // somewhere in the page <td><?php echo $currencies["eur"]["today"]; ?></td> So, every time I load, en/ or fr/ or other language, I request the exchange rates from a external site. Can I optimize this behavior (reading once per day or session)? maybe to store a global variable and check the update date?

• Reading html with accented characters from a URL on iPhone

  - by lbh

  Hello, I'm having trouble extracting the html from a website which contains accented characters. Specifically, there are French characters on the site. Currently I'm using: NSString* html= [NSString stringWithContentsOfURL: [NSURL URLWithString: url] usedEncoding: &enc error:&error]; to get html from a URL. It works perfectly fine for any sites which are all English, but with a mostly English site with French characters it returns nothing. I've tried a few different types of encoding, but none have worked for me. Any suggestions? Thanks.

• PHP 5.1.6 ArrayAccess error when iterating over object

  - 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 get around this issue? if (strpos($post['feeding_type'], 'comm')) { foreach ($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(); } }

• App.config path not correctly interpreted by ASP.NET Application

  - by seragu05

  Hello everyone ! I'm working on a very old project (2000) in VB6 which was "modernized" and upgraded to VB.NET 3.5. I've centralized every old INI configuration file into one MainApp.config, which is referenced by the app.config of every component. There's an VB ASP.NET website in the solution, which uses DLL components, which are looking into app.config for parameters like, say, error log directory, etc. I've deployed the site on my dev. server (Windows 2008 Server w/ IIS 7.0) into the D:\WebSite\ directory. Problem: When running the site, an error occurs. A DLL is looking into app.config for the parameter RepertoireErreur which has the value .\Erreurs\ Instead of returning D:\WebSite\Erreurs\ it returns c:\windows\system32\inetsrv\.\Erreurs\ which doesn't contain the Erreurs directory. Boom. Error. Does anyone have ever encountered the same problem ? Is there a solution ? Thanks,

• Question about SSL Certificate.

  - by smwikipedia

  Hi experts, I am trying to make a SSL connection to a web site. Each time I enter the https:// address and press enter, the IE8 prompts me to select the Certificate (Client Certificate) to send to the server. I got 2 certificates to choose from. And they are stored in the IE8 - Internet Options - Content - Certificates - Personal. Since my server and client are the same machine, I want to use a single certificate for both server and client. And this certificate is a IIS generated self signed certificate. I do the following steps: 1- Generate a self-signed-cert in IIS; 2- Bind my site to https and choose the above self-signed-cert 3- Import the self-signed-cert at the IE8 - Internet Options - Content - Certificates - Personal. Then I use the https link to access my page, it is still prompts me to choose a certificate. But I cannot see my newly imported self-signed-cert. Why?

• jQuery changing css on navigation when div # scrolls into view

  - by Jonny Wood

  I'm looking to recreate the effect used on this site: http://www.brizk.com/ The site uses one large page that scrolls down. As you scroll down and pass different sections the menu navigation on the left changes css class to "current" as the corresponding div comes into view. I presume this can be done with jQuery using $(window).height(); I'm fairly new to jQuery and what I want to write is something like this (in laymans terms): Get height of browser window – if div#content1 is 100px from top and/or 200px from bottom change menu a#link1 to '.current' – else remove .current from all menu a links ... and repeat for 4 different content divs. Can anyone point me in the right direction..? Thanks.

• Creating a blocked user intercepter in Grails

  - by UltraVi01

  I am working on a social site where users can block other users. Throughout the site --dozens of places, user information is displayed. For example, user comments, reply forms, online user list.. etc etc.. The problem is that given the high number of places user info is displayed, it's becoming very difficult to check each time if that user is blocked. For example: <g:each var="comment" in="${comments}"> <g:if test="!${loggedInUser.blockedUsers.find { it == comment.user}"> show comment </g:if> </g:each> Does Grails provide any functionality that would facilitate creating some kind of filter or intercepter where I could simply exclude blocked users when iterating lists, etc? If not, what would you suggest I do?

• ASP, My SQL & case sensitity suddenly broken

  - by user131812

  Hi There, We have an old ASPsite that has been working fine for years with a MY SQL database. All of a sudden last week lots fo SQL queries stopped working. The database has a table called 'members' but the code calls 'Members'. It appears the queries used to work regardless of case sensitivity on the table names, but something has changed recently somewhere to enforce case. This has me stumped as the site has not been touched in years, the server config hasn't changed & the database provide has not changed anything. Is there any simple way to ignore case for an ASP site (without editing lots fo files :) Thanks Ben

• Advise on starting a new job

  - by Sisiutl

  I hope this isn't too off-topic, but in a week I will start a new job at a manufacturing company managing the development of a new eCommerce site. The company scores about a 3 on the "Joel" test. I will inherit 3 programmers who developed the company web site and do general IT programming. I have the grey hair and credentials to have their initial respect but I'm an engineer, not a manager. I'm looking for practical advise - particularly for the first 90 days - on how to establish myself, keep the team together, and move forward.

• Should I Split Tables Relevant to X Module Into Different DB? Mysql

  - by Michael Robinson

  I've inherited a rather large and somewhat messy codebase, and have been tasked with making it faster, less noodly and generally better. Currently we use one big database to hold all data for all aspects of the site. As we need to plan for significant growth in the future, I'm considering splitting tables relevant to specific sections of the site into different databases, so if/when one gets too large for one server I can more easily migrate some user data to different mysql servers while retaining overall integrity. I would still need to use joins on some tables across the new databases. Is this a normal thing to do? Would I incur a performance hit because of this?

• SEO Language information

  - by Kevin

  I was wondering if defining your language in HTML is better for search enigines. For example, I've got a French site, then i've got three options: 1.) have faith that google can say my site is french 2.) define language in the HTML tag <html xmlns="http://www.w3.org/1999/xhtml" dir="ltr" lang="fr"> 3.) define language in a meta tag <meta http-equiv="content-language" content="FR-fr" /> Which option you believe is best? Or which combination of options?

• Can I use this Ajax script to communicate and exchange data between client and server?

  - by lala

  This block of code is for client.html (it is located in this www.client.com/client.html) - client side. The I have the code below that goes something like this: ajaxRequest.open("GET", "http://www.server.com/ajax.php", true); This is how I call the file ajax.php located in the server. Unfortunately I have no luck at all. It cannot connect to the server I'm calling. BTW, the ips /test site I've been using are all no restrictions, and is accessible to all. However, I tried to simulate by putting both client.html and ajax.php in same site and it works well. So my question is does this script works only if you are in same site? or does it work also in client-server scenario? What else do I have to do in order to make this work? //client.html <script language="javascript" type="text/javascript"> <!-- //Browser Support Code function ajaxFunction(){ var ajaxRequest; // The variable that makes Ajax possible! try{ // Opera 8.0+, Firefox, Safari ajaxRequest = new XMLHttpRequest(); } catch (e){ // Internet Explorer Browsers try{ ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) { try{ ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP"); } catch (e){ // Something went wrong alert("Your browser broke!"); return false; } } } // Create a function that will receive data sent from the server ajaxRequest.onreadystatechange = function(){ if(ajaxRequest.readyState == 4){ document.myForm.time.value = ajaxRequest.responseText; } } ajaxRequest.open("GET", "http://www.server.com/ajax.php", true); ajaxRequest.send(null); } //--> </script> <form name='myForm'> Name: <input type='text' onChange="ajaxFunction();" name='username' /> <br /> Time: <input type='text' name='time' /> </form> </body> </html> // ajax.php <?php echo date("H:i:s"); ?>

• modrewrite to another server if file/image is not found

  - by Traveling_Monk

  Hi I am working on a locally served copy of a remote site and I don't want to have to download all the images rtelated to the site so I thought i could come up with a mod_rewrite rule for to grab images from the remote server if the are not found this is the code that i have <IfModule mod_rewrite.c> RewriteEngine On RewriteCond %{REQUEST_FILENAME} -f [NC] RewriteRule ^/(.*\.(png|gif|jpg|jpeg)) https://www.exmple.com/$1 [NC,P,L] </IfModule> The page is still giving me 404's for images that are on the remote server, so this rule is not working. I do know that the htaccess is being processed because rules later in the IfModule mod_rewrite.c block are being used. (i simplified my code sample but this is the first rule in the IfModule mod_rewrite.c block)

• How do I password protect IIS in a method analogous to Apache's AuthType / AuthUserFile mechanism?

  - by Matt

  I'm used to doing basic password protection for Apache w/ the following method in Apache config files: AuthType Basic AuthName "By Invitation Only" AuthUserFile /path/to/.htpasswd Require valid-user However, I've been asked to put some protection on a subdirectory of a site running ColdFusion on top of IIS6, and I'm unfamiliar with how to do this. How is this done? What should I look out for? I just need to password protect an administrative subdirectory, so I don't need a full user login system - just something that limits who can access the section of the site.

• ASP.NET, Visual Studio and Subversion - how to integrate?

  - by Michael Stum

  I use AnkhSVN and Visual Studio 2005 and 2008. Now, one thing that bugs me is that Ankh does not really work with ASP.NET sites. I cannot add them properly to a repository and it won't detect changes, especially because the site is on a remote server accessed through Frontpage Extensions (File = Open Site). What are the alternatives? Does a better plug-in exist? Manually downloading the files through FTP and using TortoiseSVN or svn.exe is not really the level of integration I want :) I want to stay within the Visual Studio IDE when possible. Also, I do not control the remote Server, so I can not install anything on it, which means the whole change tracking/comparison to repository has to be done on my machine.

• Rewriting URL in AJAX application

  - by Artem Moskalev

  I am making a simple online application. I have a navigation bar with a few buttons and one "div" into which all the new contents will be loaded dynamically i.e. when I click "About", it will load the page parts into the "div" without reloading the whole page with .load() function. The problem is: what if I need to give a link to the Documents section of my web site, or the user wants to store this kind of link, the url is not rewritten when browsing my site. when the user stores the default link it will always link him to the default "Home" part. How can I rewrite the URL and what is the most correct way to do this?

• Are global comment systems a privacy concern?

  - by Stefano Borini

  I more and more see these global login-once comment-everywhere systems on every page. I didn't do my homework of tinkering debugging and search before asking, so my question is as follows: You login on site A and leave a comment. Now you go on site B, which uses the same global comment system. At the bottom of the page a request form with your name and data appears for you to add a comment on B page. You don't leave any comment and browse away. Does the global-comment provider get information about the fact that you visited page B, even if you don't leave any comment ? I will dig into the code as soon as I have time, but in the meanwhile I would like to ask your insights on this regard.

• process all links but external ones (ruby + mechanize)

• Windows Server 2003

  - by user229133

  I have a website that is using Windows Server 2003. The site is called https://mysite.com/ and at ip address 111.1.1.1. Now when I log into the site all my relative links that are generated using NavURL (<%# NavURL("Images/Menu/img.gif")%) are saying "http://111.1.1.1/Images/Menu/img.gif" instead of "https://mysite.com/Images/Menu/img.gif". This is causing an error because it needs to be secure. I'm sure there is a setting on the server somewhere to point to the name and not the ip, but I don't know where. Thanks for your help.

• Text to a PNG on App Engine (Python)

  - by Bemmu

  Note: I am cross-posting this from App Engine group because I got no answers there. As part of my site about Japan, I have a feature where the user can get a large PNG for use as desktop background that shows the user's name in Japanese. After switching my site hosting entirely to App Engine, I removed this particular feature because I could not find any way to render text to a PNG using the image API. In other words, how would you go about outputting an unicode string on top of an image of known dimensions (1024x768 for example), so that the text will be as large as possible horizontally, and centered vertically? Is there a way to do this is App Engine, or is there some external service besides App Engine that could make this easier for me, that you could recommend (besides running ImageMagick on your own server)?

• How can I make the boostrap js carousel automatically cycle as soon as the page loads?

  - by Jonathan Larkin

  Using bootstrap.js version 2.02 I'm trying to get the Twitter Bootstrap Carousel to automatically cycle as soon as someone visits my site. Right now, the auto cycling works only after you click one of the cycle buttons at least once. I want the carousel to begin cycling at the interval right away. Does anyone know how to do this? My site is hotairraccoon.com You'll see how after you click the carousel once, it begins to cycle every 5 seconds or so, but I don't want the click to be required to reveal carousel content. Thanks!

• Creating a "Universities Attended" Profile field/block (Drupal)

  - by Frank0051

  Interesting question for everyone. So I have am thinking of adding a "university attended" field to the profile page of members in Drupal. I guess I am trying to figure out the best way to go about it. I was originally thinking of a text field, but than I thought you could get multiple instances of of university names, making it hard to sort people by school (ie. UF, University of Florida, Florida, U of F, etc). I then began to think about creating a drop down, but I wasn't quite sure where I could get a listing of all the schools. Perhaps I could find a database population that a site like LinkedIn or Facebook uses. Then I thought of what happens when someone has attended multiple schools, how would I account for that? So, I guess I wanted to pose the question of how would you go about adding a University(ies) attended field to profile pages if you had to design a site to do so?
