  • CakePHP - radio button not showing error message

    - by teepusink
    Hi, I'm unable to get the error message to show up when creating a radio form using the CakePHP form helper. This is what I have now. $options=array('active'=>'Active','inactive'=>'Inactive'); echo $form->input('Status', array( 'type' => 'radio', 'id' => 'EntryStatus', 'name' => 'data[Entry][status]', 'options' => $options )); What am I missing? I'm using CakePHP 1.2.7 and this is what I have in the validation 'status' = array( 'notempty' = array( 'rule' = 'notempty', 'required' = true, 'message' = 'yo' ) ) Tried the answer from http://stackoverflow.com/questions/1388823/form-helper-for-creating-radio-button-in-cakephp and it's giving me a select option form instead. Thanks, Tee

  • How to handle Clean URIs in Classic ASP using PATH_INFO?

    - by Mario
    I'm trying to handle Clean URIs in a Classic ASP application. In PHP, I was able to use URIs like http://example.com/index.php/foo/bar/baz and have /foo/bar/baz available in the PATH_INFO environment variable. (I usually add a rewrite rule so I do not need the index.php segment) However, I don't seem to be able to mimic this in Classic ASP. If I try http://example.com/index.asp/foo/bar/baz, I get a 404 error. Is there a way to add a path after the index.asp segment and get the PHP like behaviour in ASP? Note: I'm currently using the workaround of rewriting URLs of the form: http://example.com/foo/bar/baz/ to index.asp?path=/foo/bar/baz since I can't seem to get index.asp/foo/bar/baz to work.

  • Pro's and Con's of unit testing after the fact.

    - by scope-creep
    I have a largish complex app around 27k lines. Its essentially a rule drive multithreaded processing engine, without giving too much away Its been partially tested as it's been built, certain components. Question I have, is what is the pro's and con's of doing unit testing on after the fact, so to speak, after its been implemented. It is clear that traditional testing is going to take 2-3+ months to test every facet, and it all needs to work, and that time is not available really. I've done a fair bit of unit testing in the past, but generally it's been on desktop automation or LOB apps, which are fairly simple. The app is itself is highly componentized internally, interface driven really. I've not decided on what particular framework to use. Any advice would be appreciated. What say you.

  • Problem with keyboard language

    - by user300484
    Hello you all! I just made an application which purpose is to find an x result using the rule of three. It runs fine and everything but there is a small problem. I am using WinXP Europpean Spanish version. As we all know, in many europpean countries the decimal dot is changed by a " , " comma. When I use my application, it turns out that when I press the dot key on my keyboard´s number pad, my application doesnt take it as a normal decimal dot and it ignores it... so I need to manually press the comma key so it can give me the right answer. How can I solve this problem?

  • Making the #include square

    - by David
    I'm trying to write a makefile using CC on Solaris 10. [Only the first bit of that really matters, I think]. I have the following rule for foo.o: foo.o: foo.cc common_dependencies.h CC -c foo.cc -I../../common Unfortunately, common_dependencies.h includes all sorts of idiosyncratic trash, in directories not named '.' or '../../common' . Is this just going to have to be a brute force makefile where I ferret out all of the dependency paths? All of the dependencies are somewhere under '../..', but sometimes 1-level down and sometimes 2-levels down.

  • Can PHP Perform Magic Instantiation?

    - by Aiden Bell
    Despite PHP being a pretty poor language and ad-hoc set of libraries ... of which the mix of functions and objects, random argument orders and generally ill-thought out semantics mean constant WTF moments.... ... I will admit, it is quite fun to program in and is fairly ubiquitous. (waiting for Server-side JavaScript to flesh out though) question: Given a class class RandomName extends CommonAppBase {} is there any way to automatically create an instance of any class extending CommonAppBase without explicitly using new? As a rule there will only be one class definition per PHP file. And appending new RandomName() to the end of all files is something I would like to eliminate. The extending class has no constructor; only CommonAppBase's constructor is called. Strange question, but would be nice if anyone knows a solution. Thanks in advance, Aiden (btw, my PHP version is 5.3.2) Please state version restrictions with any answer.

  • How can I quickly set up a RESTful site using PHP without a Framework?

    - by Sanoj
    I would like to quickly set up a RESTful site using PHP without learning a PHP Framework. I would like to use a single .htaccess-file in Apache (no mod_rewrite) or a single rule using Nginx, so I easyli can change web server without changing my code. So I want to direct all requests to a single PHP-file, and that file takes care of the RESTful-handling and call the right PHP-file. In example: The user request http://mysite.com/test The server sends all requests to rest.php The rest.php call test.php (maybe with a querystring). If this can be done, is there a free PHP-script that works like my rest.php? or how can I do this PHP-script?

  • What are the Ruby Gotchas a newbie should be warned about?

    - by MiniQuark
    I have recently learned the Ruby programming language, and all in all it is a good language. But I was quite surprised to see that it was not as simple as I had expected. More precisely, the "rule of least-surprise" did not seem very respected to me (of course this is quite subjective). For example: x = true and false puts x # displays true! and the famous: puts "zero is true!" if 0 # zero is true! What are the other "Gotchas" you would warn a Ruby newbie about?

  • Enforcing an "end" call whenever there is a corresponding "start" call

    - by Jeff Meatball Yang
    Let's say I want to enforce a rule: Everytime you call "StartJumping()" in your function, you must call "EndJumping()" before you return. When a developer is writing their code, they may simply forget to call EndSomething - so I want to make it easy to remember. I can think of only one way to do this: and it abuses the "using" keyword: class Jumper : IDisposable { public Jumper() { Jumper.StartJumping(); } public void Dispose() { Jumper.EndJumping(); } public static void StartJumping() {...} public static void EndJumping() {...} } public bool SomeFunction() { // do some stuff // start jumping... using(Jumper j = new Jumper()) { // do more stuff // while jumping } // end jumping } Is there a better way to do this?

  • Can a binary tree or tree be always represented in a Database table as 1 table and self-referencing?

    - by Jian Lin
    I didn't feel this rule before, but it seems that a binary tree or any tree (each node can have many children but children cannot point back to any parent), then this data structure can be represented as 1 table in a database, with each row having an ID for itself and a parentID that points back to the parent node. That is in fact the classical Employee - Manager diagram: one boss can have many people under him... and each person under him can have n people under him, etc. This is a tree structure and is represented in database books as a common example as a single table Employee.

  • url rewriting - build paths

    - by Cristian Boariu
    Hi guys, I have started to work on a site without url rewriting. Now, the request is to use friendly urls so i started to use Intelligencia.UrlRewriter. Let's take an example: I have a method: public static string getCategoriesIndexLink(string category) { string baseUrl = getBaseUrl() + (String)HttpContext.GetGlobalResourceObject("Paths", "categorii.index"); return baseUrl.AddQueryParam(CQueryStringParameters.CATEGORY, category); } which build this kind of urls "~/Site/Categorii.aspx?category=$1" Now i've added the following rule in web.config: <rewrite url="~/Site/Categorii/(.+)" to="~/Site/Categorii.aspx?category=$1" /> The question is HOW i can make the above method to build that kind of nice url? So no longer return "~/Site/Categorii.aspx?category=m1" but "~/Site/Categorii/m1" without beeing needed to modify its structure? I mean, i have about 30 methods like the one from the above; it would be extremely helpfull if i can be guided to use a regex at the output of the methods iso modifying the url construction... Thanks in advance...

  • Assigning a variable of a struct that contains an instance of a class to another variable

    - by xport
    In my understanding, assigning a variable of a struct to another variable of the same type will make a copy. But this rule seems broken as shown on the following figure. Could you explain why this happened? using System; namespace ReferenceInValue { class Inner { public int data; public Inner(int data) { this.data = data; } } struct Outer { public Inner inner; public Outer(int data) { this.inner = new Inner(data); } } class Program { static void Main(string[] args) { Outer p1 = new Outer(1); Outer p2 = p1; Console.WriteLine("p1:{0}, p2:{1}", p1.inner.data, p2.inner.data); p1.inner.data = 2; Console.WriteLine("p1:{0}, p2:{1}", p1.inner.data, p2.inner.data); p2.inner.data = 3; Console.WriteLine("p1:{0}, p2:{1}", p1.inner.data, p2.inner.data); Console.ReadKey(); } } }

  • Requested URL is changing

    - by user302486
    Hi, I have a website, at localhost:82 when I type this into IE, it comes up with a 404 error and the requested URL is localhost:80/wwwroot, which is not at all what I requested. There is no URL rewrite set up. I have tried to set up a tracing rule to see what is happening, however, the instructions at http://learn.iis.net/page.aspx/266/troubleshooting-failed-requests-using-tracing-in-iis-7/ say to look for "Fail Request Tracing" link, but it doesn't exist in my IIS 7.0 even under administrator. Not sure where to look or why this is changing my requested URL. Any help would be appreciated.

  • JSF tags not being rendered as HTML

    - by Toto
    I'm following the Java EE firstcup tutorial using Netbeans and Glassfish. When I execute the JSF web tier I've been instructed to code, the browser gets the same JSF markup coded in the .xhtml file, and the tags are not rendered as HTML tags. I know this by using the view source code in my browser. For example, for this code: <html xmlns="http://www.w3.org/1999/xhtml" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html"> <h:head> <title>Page title here</title> </h:head> <h:body> <h2> <h:outputText value="#{bundle.WelcomeMessage}" /> </h2> </h:body> </html> The browser should get something like: <html ...> <head> <title>Page title here</title> </head> <body> <h2> the welcome message goes here </h2> </body> </html> Right? Well, my browser is getting jsf code (the first piece of code above) and not the html code (the second piece of code above). It seems to be a configuration problem in netbeans or glassfish but don't know what. Any ideas? This is my web.xml file: <?xml version="1.0" encoding="UTF-8"?> <web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"> <context-param> <param-name>javax.faces.PROJECT_STAGE</param-name> <param-value>Development</param-value> </context-param> <servlet> <servlet-name>Faces Servlet</servlet-name> <servlet-class>javax.faces.webapp.FacesServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>Faces Servlet</servlet-name> <url-pattern>/firstcup/*</url-pattern> </servlet-mapping> <session-config> <session-timeout> 30 </session-timeout> </session-config> <welcome-file-list> <welcome-file>greetings.xhtml</welcome-file> </welcome-file-list> </web-app> This is my faces-config.xml file: <?xml version='1.0' encoding='UTF-8'?> <!-- =========== FULL CONFIGURATION FILE ================================== --> <faces-config version="2.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd"> <application> <resource-bundle> <base-name>firstcup.web.WebMessages</base-name> <var>bundle</var> </resource-bundle> <locale-config> <default-locale>en</default-locale> <supported-locale>es</supported-locale> </locale-config> </application> <navigation-rule> <from-view-id>/greetings.xhtml</from-view-id> <navigation-case> <from-outcome>success</from-outcome> <to-view-id>/response.xhtml</to-view-id> </navigation-case> </navigation-rule> </faces-config> Moreover: The url I'm entering in the browser is http://localhost:8081/firstcup/ but I've also tried: http://localhost:8081/firstcup/greetings.xhtml I've checked Glassfish logs and there's no information about not being able to load FacesServlet

  • How can I redirect all traffic from one domain to another with an .htaccess file?

    - by George Edison
    Say I have a subdomain xxx.yyy.com running Apache. The files are stored in /home/someone/public_html/xxx. What I want to do is redirect all requests to a domain name zzz.com which is using the same location for its files. (In other words, xxx.yyy.com and zzz.com are aliases for each other) I just want people accessing zzz.com, so if someone goes to xxx.yyy.com they should be redirected to zzz.com. Can this easily be done with a rewrite rule in an .htaccess file?

  • Multiple Asserts in a Unit Test

    - by whatispunk
    I've just finished reading Roy Osherove's "The Art of Unit Testing" and I am trying to adhere to the best practices he lays out in the book. One of those best practices is to not use multiple asserts in a test method. The reason for this rule is fairly clear to me, but it makes me wonder... If I have a method like: public Foo MakeFoo(int x, int y, int z) { Foo f = new Foo(); f.X = x; f.Y = y; f.Z = z; return f; } Must I really write individual unit tests to assert each separate property of Foo is initialized with the supplied value? Is it really all that uncommon to use multiple asserts in a test method? FYI: I am using MSTest.

  • is it possible if callback in array_filter receive parameter ?

    - by justjoe
    i got this multiple array name $files[], who consist keys and values as below : [0] = Array ( [name] = index1.php [path] = http://localhost/php/gettingstarted/ [number] = 1 ) [1] = Array ( [name] = index10.php [path] = http://localhost/php/gettingstarted/ [number] = 2 ) [2] = Array ( [name] = index11.php [path] = http://localhost/php/gettingstarted/ [number] = 3 ) and i use this code to create new array consist of 'name' keys only. but it failed array_filter($files, "is_inarr_key('name')"); function is_inarr_key($array, $key) { //TODO : remove every array except those who got the same $key } and i got this error array_filter() [function.array-filter]: The second argument, 'is_inarr_key('name')', should be a valid callback in C:\xampp\htdocs\php\gettingstarted\index.php on line 15 so the queastion : 1. is it possible to make call-back function on array_filter has ability to receive parameter ? What is general rule of thumb on how to use callback in anyPHP built-in function ?

  • How to free memory in try-catch blocks?

    - by Kra
    Hi, I have a simple question hopefully - how does one free memory which was allocated in the try block when the exception occurs? Consider the following code: try { char *heap = new char [50]; //let exception occur here delete[] heap; } catch (...) { cout << "Error, leaving function now"; //delete[] heap; doesn't work of course, heap is unknown to compiler return 1; } How can I free memory after the heap was allocated and exception occurred before calling delete[] heap? Is there a rule not to allocate memory on heap in these try .. catch blocks? Thanks

  • Writing shorter code/algorithms, is more efficient (performance)?

    - by Carlos
    After coming across the code golf trivia around the site it is obvious people try to find ways to write code and algorithms as short as the possibly can in terms of characters, lines and total size, even if that means writing something like: n=input() while n>1:n=(n/2,n*3+1)[n%2];print n So as a beginner I start to wonder whether size actually matters :D. It is obviously a very subjective question highly dependent on the actual code being used, but what is the rule of thumb in the real world. In the case that size wont matter, how come then we don't focus more on performance rather than size?

  • Why doesn't C# allow for global inferred types i.e. using var?

    - by BritishDeveloper
    I know it can't be done since using var can only be done for local variables. I'm just wondering if anyone has a theory why the C# team thought this should be so. e.g. what would be wrong with this: public class SomeClass { var someString = "hello"; //not cool public SomeClass() { var someOtherString = "hello"; //cool } } If someString is initialised then it is obviously a string just like someOtherString. Why is there one rule for local variables and another for globals?

  • how to insert based on the date

    - by Gaolai Peng
    I have a table table1 (account, last_contact_date, insert_date), account and last_contact_date are primary keys. The insert_date is set with the time the recored being added by calling getdate(). I also have a temporary table #temp(account, last_contact_date) which I use to update the table1. Here are sample data: table1 account last_contact_date insert_date 1 2012-09-01 2012-09-28 2 2012-09-01 2012-09-28 3 2012-09-01 2012-09-28 #temp account last_contact_date 1 2012-09-27 2 2012-09-27 3 2012-08-01 The result table depends on the inserting date. If the date is 2012-09-28, the result will be table1 account last_contact_date insert_date 1 2012-09-27 2012-09-28 2 2012-09-27 2012-09-28 3 2012-09-01 2012-09-28 If the date is 2012-09-29, the result will be table1 account last_contact_date insert_date 1 2012-09-01 2012-09-28 2 2012-09-01 2012-09-28 3 2012-09-01 2012-09-28 1 2012-09-27 2012-09-29 2 2012-09-27 2012-09-29 Basically the rule is (1) if the inserting date is the same day, i will pick the lastest last_contact_date, otherwise, (2) if the last_contact_date is later than the current last_contact_date, I will insert a new one. How do I write a query for this insert?

My question is, how i can build a load-time DLL (or run-time DLL is also fine) with these .lib files? More Info: I am building my project with bjam in windows using msvc. When i tried compiling my project under visual C++ 2008, it complied and linked just fine but when i used bjam with msvc for compilation, it started giving linking errors and showing dependency from other project folders. Why was this behavior via bjam but not shown in vc++ UI.
