• A help system for a PHP web app

  - by Dave

  Hi, As our new web app gets more complicated, so the need for help docs increases. I am not talking about documenting code, I am literally talking about application help. So myapp/help, or for example, enabling context help from a particular point in the app with a link such as myapp/help/users/create/ etc. Are there apps out there for doing this? For example, Wufoo use wordpress for http://wufoo.com/docs/ which I like (and understand wp, so its a nice solution), and Xero have a lovely ASPX http://help.xero.com/ interface. But I'm thinking there might be more dedicated implementations for what I'm looking for. We're on a linux, apache, postgresql, php stack, but a mysql supported installation is not the end of the world. Does anyone have any suggestions for this? It's a bit of a minefield when googling php + help + system.

• Annotating axis in ggplot2

  - by mpiktas

  I am looking for the way to annotate axis in ggplot2. The example of the problem can be found here: http://learnr.wordpress.com/2009/09/24/ggplot2-back-to-back-bar-charts. The y axis of the chart (example graph in the link) has an annotation: (million euro). Is there a way to create such types of annotations in ggplot2? Looking at the documentation there is no obvious way, since the ggplot does not explicitly let you put objects outside plotting area. But maybe there is some workaround? One of the possible workarounds I thought about is using scales: data=data.frame(x=1:10,y=1:10) qplot(x=x,y=y,data=data)+scale_y_continuous(breaks=10.1,label="Millions") But then how do I remove the tick? And it seems that since ggplot does not support multiple scales, I will need to grab the output of the scale_y_continuous, when it calculates the scales automaticaly and then add my custom break and label by hand. Maybe there is a better way?

• What is the difference between DVCS systems?

  - by Stephen

  What is the difference between DVCS systems? Seriously, wikipedia doesn't cover it well, and I read an article on HN recently comparing git and bzr in some detail, but the author admitted knowing little about mercurial, and the other options didn't get mentioned. (I'm happily using fossil on small win/mac/Linux projects) Please restrict answers to the DVCS aspects of the tool, e.g. The basic unit of vc in hit is the repository- in bazaar it is the branch(http://unspecified.wordpress.com/2010/03/26/why-git-aint-better-than-x/). bugtrackers and wikis are nice, but I'm really interested in the tools themselves, rather than any extras. Unfortunately SO demands a single 'right answer', so I'm making the question community wiki in the hope that users will contribute their knowledge.

• Resources for rails widget creation

  - by Kenji Crosland

  My rails app is about to go live and I'm trying to figure out how to create a widget based on data on the site. My Javascript is not too hot--limited to the O'reilly head first book on JS. I can read simple Javascript okay but when it comes to writing it I'm a little lost. That said, I hope to roll out a widget, maybe a wordpress plugin too soon after my app is launched. Does anyone know of any rails plugins, javascript templates, tutorials or books that can get me going? I did ask a similar question before here: But my limited knowledge of JS kept me from implementing the suggested answer properly.

• jQuery Select Menu Replacement

  - by Brad

  I have a select drop-down that selects a theme for the current page the user is on: <select id="style" name="acct-stylenum"> <option value="1" selected="true">Light</option> <option value="2">Dark</option> </select> Now what I would like to do is add two divs that will also control this select menu. I would much rather have the user select between two images than a select menu. The divs are as follows: <div class="style-box light"></div> <div class="style-box dark"></div> I would like to use jQuery to make the select menu hidden but still use its input. Also I would like the divs to control the menus value and show a selected state. Please let me know the easiest way this can be done using jQuery or JavaScript. Thanks in advance. -B

• Entity Data Model & DataGridView - Creating new objects

  - by AcousticBoom

  I'm pretty new to the EDM, so bear with me. I have a windows form that has a DataGridView on it that's bound from the EDM I created. I figured out how to update my changes fine, but it's when the user creates a new row that I'm having a problem. I tried numerous ways and many google searches, but came up with nothing so far. Here's how the data is loaded: Dim boilerID As Integer = DirectCast(ddlBoiler.SelectedValue, Integer) Dim countryID As Integer = DirectCast(ddlCountry.SelectedValue, Integer) Dim ratings = From r In _Context.Rating _ Where r.Boiler.Boiler_ID = boilerID _ And r.Country.Country_ID = countryID _ Order By r.Sequence _ Select r RatingBindingSource.DataSource = ratings.ToList() Also, all I'm doing to save the information right now is the following: Private Sub btnSave_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSave.Click _Context.SaveChanges() End Sub I want the user to be able to use the grid's "new row" feature to add new items to the database instead of having to click a button and open a new dialog. How would this be accomplished? I can include some of the methods i tried for adding new items if anyone needs to see. Thanks!

• vBulletin Nightmare

  - by Chris

  I am creating a vBulletin forum community called: wehypnosis We purchased the vBulletin version 4.0 CMS and the SEO plugin. Im used to designing and building templates for drupal, wordpress and joomla. All of which have great documentation and many tutorials built by the community. But vBulletin although claimed as the best forum software on the internet, is missing any form of documentation worth reading. The only thing I can find to help me rebuild this monster is www.vbulletin.com/docs/ Does anyone know of a set of tutorials or any documentation which would help me: Configure a good solid working version? Give detailed instruction on how to build themes for vBulletin? Drupal has a mountain of great books and resources. Does vBulletin?

• Installing Recaptcha in Joomla 1.5 user registration

  - by Samuel

  I am trying to install ReCaptcha into the user registration of Joomla 1.5. This may just be an issue with Joomla but when i hit register nothing happens. I think it's doing some JavaScript form validation but there is nothing telling the user what went wrong. if, God forbid, they do fill out the form correctly Joomla will redirect the user to the homepage and give no notice of success. Is this a Joomla issue or is there something wrong with my install? Does anyone know of a plug-in or module for Joomla that would make this easier? Thanks in advance, Samuel UPDATE: Joomla does a lot of "stuff"/"something" to the $_POST and $_GET variables which was causing the reCaptcha to not function. This was for work which is past so I am not spending anymore time on it. Shameless Plug: use wordpress instead. this can be closed as I don't have time to verify which answer works

• PHP CMS with independent framework.

  - by Simon

  We currently use MySource Matrix CMS for large projects, Wordpress CMS for small projects and Zend Framework for bespoke applications... I'm not trying to confuse and compare a CMS to a framework, that has been done before :-) I want to identify a few CMSs for review that have foundations in strong (preferably independent) PHP frameworks. The only one I have looked at is SilverStripe CMS and Sapphire Framework. We have many clients that have a CMS for internet and/ or extranet and then various other bespoke applications that are then integrated via various means to look like they're in the CMS. I believe it will be more productive and beneficial to have a common framework between these branches so they can be natively merged. Hope this makes sense. PS. I have used custom assets in MySource Matrix and specific modules in other CMS but you feel you are working for the CMS not the application you are building.

• PrestaShop vs. Shopify

  - by Zach L.

  I have seen several Questions comparing different ECommerce CMS's: Prestashop compared to Zen-Cart and osCommerce Magento or Prestashop, which is better? Best php/ruby/python e-commerce solution I was hoping to get some people to weigh in with which they prefer for a relatively small E-shop. I am now primarily looking at PrestaShop and Shopify. I really like that Shopify does the hosting, has quality service, and is simple to understand and theme. However PrestaShop is free and seems to be able to do just as much if not more than Shopify. I have decided that Magento is too clunky for the project, and have read that many other solutions (osCommerce, ZenCart, OpenCart) are outdated, buggy, or just inferior. Thank you!

• Sorting Anonymous Types

  - by strobaek

  I have a question of how to sort an anonymous type. Using Linq2SQL I have the following query, which returns a list of submissions: var submissions = EventSubmissions .Where(s => s.EventId.Equals(eventId)); Consider the following interface (somewhat simplyfied): public interface IQuerySorter { IOrderedQueryable Sort(IQueryable query); IOrderedQueryable<T> Sort<T, U>(IQueryable<T> query, Expression<Func<T,U>> selector); ... } Using this interface allows me to implement a number of 'sorters', e.g. on Date, Rating or whether or not a submission has been nominated (for voting). sortedQuery = sorter.Sort(submissions) So far so good. A submission can be made "votable". I get the number of votes a nominated submission may have using the following query: var withVoteCount = submissions .Select(s => new {NumberOfVotes = s.Votes.Count(), Submission = s}); I would like to sort this new query by NumberOfVotes using my "general" sorter class, but run into the problem that the anonymous type/member does not seem to live outside the repository-method, hence I am unable to sort on it. Any input would be greatly appreciated.

• Which is a good opensource user management system?

  - by Lost_in_code

  I'm new to php/mySQL and am trying to create a website which will allow users to register. In future, there will be a paid content area where content will be shown based on the payment status. Is there a good opensource lightweight framework which takes care of the user management part? (Register, edit user info, retrieve lost password etc). I'm a flash platform developer and not aware of how to take care of stuff like session hijacking, XSS etc. Should I go ahead and learn to do all this on my own, without using any framework? I thought of using Wordpress' user management system, but not sure how easy that would be. Any suggestion would be great.

• Embedded views and resources (mvc)

  - by Steve Ward

  Hi I've embedded several views in a library so that I can re-use across projects using this method which works OK: http://www.wynia.org/wordpress/2008/12/aspnet-mvc-plugins/ But one view usings a Javascript file. I've tried marking this as an embedded resource and adding it AssemblyInfo.cs and then referencing this resource using <%= ClientScript.GetWebResourceUrl(this.GetType(), "FullPath.FileName.js")%> This is literally displaying this output in the view WebResource.axd?d=nUxqfqAUQLabLU54W I think this is because Im trying to refer to an embedded resource from an embedded resource. Help appreciated as Im going round in circles.. Steve

• open_basedir vs sessions

  - by liquorvicar

  On a virtual hosting server I have the open_basedir set to .:/path/to/vhost/web:/tmp:/usr/share/pear for each virtual host. I have a client who's running WordPress and he's complaining about open_basedir errors thus: PHP WARNING: file_exists() [function.file-exists]: open_basedir restriction in effect. File(/var/lib/php/session/sess_42k7jn3vjenj43g3njorrnrmf2) is not within the allowed path(s): (.:/path/to/vhost/web:/tmp:/usr/share/pear) So the PHP session save_path isn't included in open_basedir but sessions across all sites on the server seems to be working fine apart from in this intermittent instance. I thought that perhaps the default session handler ignored open_basedir and this warning was caused by WP accessing the session file directly. However from what I can see PHP 5.2.4 introduced open_basedir checking to the session.save_path config: http://www.php.net/ChangeLog-5.php#5.2.4 (I am on PHP 5.2.13). Any ideas?

• What AMF Servers Support Remote Shared Objects?

  - by GrayB

  Greetings. I'm planning on building a Flex based multiplayer game, and I'm researching what will be required for the server end. I have PHP experience, so I started looking at ZendAMF. Now in this game, I'll need the concept of rooms, and real time updates to clients in those rooms, so it looks like I'll be using remote shared objects (correct, yes?). I'm not seeing where ZendAMF can support this. So I found this page: http://arunbluebrain.wordpress.com/2009/03/04/flex-frameworks-httpcorlanorg/ It seems to indicate that ZendAMF isn't going to do what I want. WebORB for PHP seems to be the only PHP based solution that does messaging, but on that page it doesn't mention "real-time" next to it like the Java based ones below it do. What should I be looking at for the server piece with my requirements? Do I need to make the jump to something like BlazeDS and try to pick up a bit of Java knowledge? Thanks.

• Correctly assigning value to a Core Data attribute with an integer data-type

  - by Gordon Fontenot

  I'm missing something here, and feeling like an idiot about it. I'm using a UIPickerView in my app, and I need to assign the row number to a 32-bit integer attribute for a Core Data object. To do this, I am using this method: -(void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component { object.integerValue = row; } This is giving me a warning: warning: passing argument 1 of 'setIntegerValue:' makes pointer from integer without a cast What am I mixing up here? --Edit 1-- Ok, so I can get rid of the warning by changing the method to do the following: NSNumber *number = [NSNumber numberWithInteger:row]; object.integerValue = rating; However, I still get a value of 0 for object.integerValue if I use NSLog to print it out. object.integerValue has a max value of 5, so I print out number instead, and then I'm getting a number above 62,000,000. Which doesn't seem right to me, since there are 5 rows. If I NSLog the row variable, I get a number between 0 and 5. So why do I end up with a completely different number after casting the number to NSNumber? --Edit 2-- Ok, so I'm realizing that there is some fundamental idea that I don't understand. I now understand that the 60 million + number can be cast back to the correct 0-5 number by using integerValue. So, it seems my question is how can I save an integer between 0-5 to the attribute if the NSNumber that is returned is over 60 million? Do I need to be using a different data type?

• How to map old paths to Drupal paths

  - by kidrobot

  I'm converting a Wordpress blog to Drupal and need to map the WP paths to the new Drupal ones. What's the best practice for doing this? There are only around a hundred pages to map. I've been experimenting with the URL Alter module, which provides an alternative to messing with custom_url_rewrite functions settings.php but keep getting 404. Waiting to hear back from the module maintainer if this is what the module is intended for. In the meantime I am wondering how others do this? Should I be using .htaccess?

• Move a legend in ggplot2

  - by Dan Goldstein

  I'm trying to create a ggplot2 plot with the legend beneath the plot. The ggplot2 book says on p 112 "The position and justification of legends are controlled by the theme setting legend.position, and the value can be right, left, top, bottom, none (no legend), or a numeric position". The following code works (since "right" it is the default), and it also works with "none" as the legend position, but "left", "top", "bottom", all fail with "Error in grid.Call.graphics("L_setviewport", pvp, TRUE) : Non-finite location and/or size for viewport" library(ggplot2) (myDat <- data.frame(cbind(VarX=10:1, VarY=runif(10)), Descrip=sample(LETTERS[1:3], 10, replace=TRUE))) qplot(VarX,VarY, data=myDat, shape=Descrip) + opts(legend.position="right") What am I doing wrong? Re-positioning a legend must be incredibly common, so I figure it's me.

• Database design in blogging systems

  - by Peter

  As a learning exercise I'm trying to put myself a blogging system. The goal is to code something that will let me create multiple blogs, like blogger.com or wordpress.com, but much simplified. I would like to ask you, what do you think is best database design for this type of script. Is it better to have one big table, containing posts from all blogs of all users (like friendfeed) or would it be better to create separate table for each blog's posts? Big thanks in advance for your help, Peter.

• Hooks...exactly what they are

  - by Ygam

  I have seen hooks in Kohana PHP framework, and they work as some sort of a callback function triggered by a certain event (Kohana's events that is, some sort of method overloading). I have seen hooks in Wordpress, and I don't know what they are or how to use them (just saw them yesterday). I'm looking for events in "non-frameworked" php, I cannot find ones. Do hooks work only in an "event-based" environment? What are they anyway (in general, not just in PHP)? What are they good for if not in an "event-based" environment.
