  • Zend Framework: How to start PHPUnit testing Forms?

    - by Andrew
    I am having trouble getting my filters/validators to work correctly on my form, so I want to create a Unit test to verify that the data I am submitting to my form is being filtered and validated correctly. I started by auto-generating a PHPUnit test in Zend Studio, which gives me this: <?php require_once 'PHPUnit/Framework/TestCase.php'; /** * Form_Event test case. */ class Form_EventTest extends PHPUnit_Framework_TestCase { /** * @var Form_Event */ private $Form_Event; /** * Prepares the environment before running a test. */ protected function setUp () { parent::setUp(); // TODO Auto-generated Form_EventTest::setUp() $this->Form_Event = new Form_Event(/* parameters */); } /** * Cleans up the environment after running a test. */ protected function tearDown () { // TODO Auto-generated Form_EventTest::tearDown() $this->Form_Event = null; parent::tearDown(); } /** * Constructs the test case. */ public function __construct () { // TODO Auto-generated constructor } /** * Tests Form_Event->init() */ public function testInit () { // TODO Auto-generated Form_EventTest->testInit() $this->markTestIncomplete( "init test not implemented"); $this->Form_Event->init(/* parameters */); } /** * Tests Form_Event->getFormattedMessages() */ public function testGetFormattedMessages () { // TODO Auto-generated Form_EventTest->testGetFormattedMessages() $this->markTestIncomplete( "getFormattedMessages test not implemented"); $this->Form_Event->getFormattedMessages(/* parameters */); } } so then I open up terminal, navigate to the directory, and try to run the test: $ cd my_app/tests/unit/application/forms $ phpunit EventTest.php Fatal error: Class 'Form_Event' not found in .../tests/unit/application/forms/EventTest.php on line 19 So then I add a require_once at the top to include my Form class and try it again. Now it says it can't find another class. I include that one and try it again. Then it says it can't find another class, and another class, and so on. I have all of these dependencies on all these other Zend_Form classes. What should I do? How should I go about testing my Form to make sure my Validators and Filters are being attached correctly, and that it's doing what I expect it to do. Or am I thinking about this the wrong way?

  • Inheritance using prototype / "new"

    - by mikkol
    Hi I'm new in Javascript OO and want to know more about about inheritance. Hope you can provide some advice! I see this great post: How to "properly" create a custom object in JavaScript? which talks about how a class is inherited as I see in other websites, ex.: function man(x) { this.x = x; this.y = 2; } man.prototype.name = "man"; man.prototype.two = function() { this.y = "two"; } function shawn() { man.apply(this, arguments); }; shawn.prototype = new man; The above post claims that in order not to call "man"'s constructor while inheriting, one can use a helper like this instead: function subclassOf(base) { _subclassOf.prototype= base.prototype; return new _subclassOf(); } function _subclassOf() {}; shawn.prototype = subclassOf(man); While I understand its intention, I don't see why we can't call shawn.prototype = man.prototype; I see it works exactly the same. Or is there something I'm missing? Thanks in advance!

  • add JButton into frame with JTable

    - by Edan
    hello, I would like to know how to put a button inside a frame that contain JTable inside. (The button should not be inside a cell, but after the table ends) Here is the example code I wrote so far: class SimpleTableExample extends JFrame { // Instance attributes used in this example private JPanel topPanel; private JTable table; private JScrollPane scrollPane; private JButton update_Button; // Constructor of main frame public SimpleTableExample() { // Set the frame characteristics setTitle("Add new item" ); setSize(300, 200); setBackground( Color.gray ); // Create a panel to hold all other components topPanel = new JPanel(); topPanel.setLayout( new BorderLayout() ); getContentPane().add( topPanel ); // Create columns names String columnNames[] = {"Item Description", "Item Type", "Item Price"}; // Create some data String dataValues[][] = {{ "0", "Entree", "0" }}; // Create a new table instance table = new JTable( dataValues, columnNames ); //////////////////////////// JComboBox item_Type_Combobox = new JComboBox(); item_Type_Combobox = new JComboBox(item_Type.values()); TableColumn column = table.getColumnModel().getColumn(1); column.setCellEditor(new DefaultCellEditor(item_Type_Combobox)); //////////////////////////// // Add the table to a scrolling pane scrollPane = new JScrollPane( table ); topPanel.add( scrollPane, BorderLayout.CENTER ); } } How do I add button after the table I created? thanks in advance

  • Is it possible to handle User Defined Exception using JAX WS Dispatch API ?

    - by snowflake
    Hello, I'm performing dynamic webservices call using following code snippet: JAXBContext jc = getJAXBContext(requestClass, responseClass, jaxbContextExtraClasses); Dispatch<Object> dispatch = service.createDispatch(portQName, jc, Service.Mode.PAYLOAD); Object requestValue = getRequestValue(requestClass, pOrderedParameters); JAXBElement<?> request = new JAXBElement(new QName(serviceQNameStr, pOperationName), requestValue.getClass(), null, requestValue); Object tmpResponse = dispatch.invoke(request); Invocation works perfectly, except if I add a user defined exception on the service (a basic UserException extends java.lang.Exception). First I get: javax.xml.bind.UnmarshalException: unexpected element (uri:"http://schemas.xmlsoap.org/soap/envelope/", local:"Fault"). Expected elements are <{http://my.namespace/}myMethod,<{http://my.namespace/}myResponse Then I added the UserException_Exception JAX-WS generated type to my JAXB Context, and then get: Caused by: com.sun.xml.bind.v2.runtime.IllegalAnnotationsException: 1 counts of IllegalAnnotationExceptions java.lang.StackTraceElement does not have a no-arg default constructor. this problem is related to the following location: at java.lang.StackTraceElement at public java.lang.StackTraceElement[] java.lang.Throwable.getStackTrace() at java.lang.Throwable at java.lang.Exception Only solution available I found are: dispatch directly a Soap message and handle Soap fault directly (this is the way Jboss JAX-WS implementation performs a standard JAX-WS call using services interfaces). This is not an available solution for me, I want to use a high level implementation (the more I get close to Soap message the less dynamic my code can be) usage of JAXBRIContext.ANNOTATION_READER, which is implementation specific and not an available solution for me, in order to annotate annotates java.lang.Exception as @XmlTransient The service with a user defined exception performs well using the JAX-WS generated standard client stubs and using a tool such Soap UI. Problem occurs in deserialization of the message when I have no user defined exception artifact in the JAXB context, and during invocation when I add those non JAXB compatible artifacts in the JAXB context. I'm usign Jboss WS webservice stack within Jboss 4.2.3.GA Any elegant solution to this problem is welcomed !

  • Simulate Windows Service with ASP.NET

    - by Bayonian
    Hi, I have small web app that generate PDF files as a report. I'm trying to delete those generated PDF files after 10 sec that they are generated. What I want to do is to read a folder with PDF files every 10 sec, and delete all the PDF files inside that folder. I read this post of Easy Background Tasks in ASP.NET. The following code is the VB version. Protected Sub Application_Start(ByVal sender As Object, ByVal e As EventArgs) AddTask("DoStuff", 10) End Sub Private Sub AddTask(ByVal name As String, ByVal seconds As Integer) OnCacheRemove = New CacheItemRemovedCallback(CacheItemRemoved) HttpRuntime.Cache.Insert(name, seconds, Nothing, DateTime.Now.AddSeconds(seconds), Cache.NoSlidingExpiration, CacheItemPriority.NotRemovable, _ OnCacheRemove) End Sub Public Sub CacheItemRemoved(ByVal k As String, ByVal v As Object, ByVal r As CacheItemRemovedReason) ' do stuff here if it matches our taskname, like WebRequest DeletePDFilesInFoler() ' re-add our task so it recurs AddTask(k, Convert.ToInt32(v)) End Sub But I got this error Delegate 'System.Web.Caching.CacheItemRemovedCallback' requires an 'AddressOf' expression or lambda expression as the only argument to its constructor. If this code works, where I should put it. Right, now I'm putting it in the master page. How to get this error out? Thank you

  • [AS3] BitmapData cut-off

    - by Fristi
    Hello, I am writing a MovieClip rasterizer which rasterizes all the frames in the specified movieclip. Here's the code for rasterizing: for ( var i:int = start; i <= end; i++ ) { //goto the next frame clip.gotoAndStop( i ); //get the bounds bounds = clip.getBounds(clip); //create a new bitmapdata container bitmapData = new BitmapData( transformer.width == -1 ? bounds.width : transformer.width, transformer.height == -1 ? bounds.height : transformer.height, transformer.transparent, transformer.color ); //rotate the clip if (clip.rotation != 0) transformer.rotate( clip.rotation * (Math.PI / 180) ); //scale the clip if (clip.scaleX != 1 || clip.scaleY != 1) transformer.scale( clip.scaleX, clip.scaleY ); //translate the movieclip to its zero point if (transformer.matrix.tx == 0 && transformer.matrix.ty == 0) transformer.translateToZero( bounds ); //draw the bitmap data with the transformers bitmapData.draw( this._source, transformer.matrix, transformer.colorTransform, transformer.blendMode, transformer.clipRect, //new Rectangle(0, 0, bounds.width, bounds.height), transformer.smoothing ); //push the data on the array frames.push( bitmapData ); } Now the result is different - http://i42.tinypic.com/lfv52.jpg - (note the head and left shoe). Anyone knows what the problem is? I've seen people adding 'extra' pixels to their boundary box at the BitmapData constructor, but thats nasty imo.

  • Correct use of WSDL-generated sources

    - by John K
    How can I easily convert between manually written classes and WSDL-generated equivalents? I have a Java SE 6 thick client that calls a web service to get and store data. The client has a DAO that works with my entity classes, calls <Entity.toDto() to convert them to DTOs, and sends/receives that data with the web service. My issue stems from the fact that the entity classes live on both sides of the service interface: client and server. Each entity has a constructor from the DTO and a toDto function: public class EntityClass { public EntityClass(EntityClassDto dto); public EntityClassDto toDto(); ... } This means I have a handwritten DTO class that the client and server both use. However, the service interface expects the WSDL-generated classes. I have tried writing conversion code between the hand-written DTO and the WSDL-generated DTO and it is tedious and error-prone. What is a reasonable alternative to this? Some back-story: The thick client should be able to have a configurable backend: either direct to the DB or through this web service. The aforementioned DAO is the web service based implementation and another imlpementation that is JPA-based exists.

  • Using Google Visualization in GWT 2.0

    - by nick
    I'm working on learning GWT (total newb) and have a question regarding the Visualiztion API provided by Google. This page: http://code.google.com/p/gwt-google-apis/wiki/VisualizationGettingStarted Describes getting started with a pie chart (which is what I need). However I'm trying to do this in a composite UI using UiBinder. To that end I don't know how to handle the callback correctly that is shown: public class SimpleViz implements EntryPoint { public void onModuleLoad() { // Create a callback to be called when the visualization API // has been loaded. Runnable onLoadCallback = new Runnable() { public void run() { Panel panel = RootPanel.get(); // Create a pie chart visualization. PieChart pie = new PieChart(createTable(), createOptions()); pie.addSelectHandler(createSelectHandler(pie)); panel.add(pie); } }; // Load the visualization api, passing the onLoadCallback to be called // when loading is done. VisualizationUtils.loadVisualizationApi(onLoadCallback, PieChart.PACKAGE); } My First assumption is this would go in the UiBinder constructor, correct? Yet this assumes that I want to place the element in the RootLayoutPanel, and I don't. I can't see an elegant and obvious way of placing it in the binder. I submit that even this guess may be wrong. Any ideas from the experts?

  • VB.Net Custom Object Master-Detail Data Binding

    - by clawson
    Since beginning to use VB.Net some years ago I have become slowly familiar with using the data binding features of .Net, however I often find my self bewildered by it's behavior and instead of discover the correct way it should work I find some dirty work around to suit my needs and continue on. Needless to say my problems continue to arise. I am using Custom Objects as the Data Sources for by controls and often entire forms. I find it frustrating to separate business logic and the graphical interface. (That could be a new question entirely.) So for a lot of objects I generate a form which has the DataBindingSource for the object. When I create each from using the New Constructor I explicitly pass to it the object to which it should be bound, and then set this passed object as the DataSource of the BindingSource. (That's a mouthful!) Now the Master object (say, bound to each form) often contains a List of objects which I like to have displayed in a DataGridView. I (sometimes) create and modify these child objects in their own form (again creating a databind the same way as the master form) but when I add them to the List in the master object the DataGridView won't update with the new items. So my question really has a few layers: How can I easily/efficiently/correctly update this DataGridView with the list of Detail objects when I add them to the list of the Master object. Is this approach to DataBinding good/viable. What's the best way to separate business logic from graphical interface. Thanks for the help!

  • Using jQuery, setting Draggable on an element prevents blur from firing when you click the draggable

    - by Danno
    Using jQuery, when you set a blur event on a text box and set another element as draggable, when you click the draggable element, the blur event does not fire in FireFox. IE is a little better, you get the blur event but you don't get the click event on the draggable element. If you don't specify the cancel: "" in the draggable constructor, you will get the blur event to fire, but then the element you want to drag is not draggable. jQuery v1.3.2 jQuery UI v1.7.2 The console.log lines are for FireFox's FireBug plugin. <HTML> <HEAD> <TITLE>Blur/Click Workbench</TITLE> <script src="js/jquery.js" type="text/javascript" ></script> <script src="js/ui/ui.core.js" type="text/javascript"></script> <script src="js/ui/ui.draggable.js" type="text/javascript"></script> <script type="text/javascript"> function blurring() { console.log('1 - blurring - ' + $( this ).attr('id')); } function clicking() { console.log('2 - clicking - ' + $( this ).attr('id')); } $(document).ready(function() { $( ".draggableTool" ).draggable( { cancel: "" } ); $( '.property' ).blur( blurring ); $( '#labelContainer' ).click( clicking ); }); </script> </HEAD> <BODY> <input type='text' class='property' id='tb1' /> <br /> <input type='text' class='property' id='tb2' /> <br /> <label class='draggableTool' id='labelContainer' style='height:20px;position:absolute;'> <textarea id='taLabel' style='height:100%;background-color:white;border:1px solid grey;'>Label</textarea> </label> </BODY> </HTML>

  • Blackberry read local properties file in project

    - by Dachmt
    Hi, I have a config.properties file at the root of my blackberry project (same place as Blackberry_App_Descriptor.xml file), and I try to access the file to read and write into it. See below my class: public class Configuration { private String file; private String fileName; public Configuration(String pathToFile) { this.fileName = pathToFile; try { // Try to load the file and read it System.out.println("---------- Start to read the file"); file = readFile(fileName); System.out.println("---------- Property file:"); System.out.println(file); } catch (Exception e) { System.out.println("---------- Error reading file"); System.out.println(e.getMessage()); } } /** * Read a file and return it in a String * @param fName * @return */ private String readFile(String fName) { String properties = null; try { System.out.println("---------- Opening the file"); //to actually retrieve the resource prefix the name of the file with a "/" InputStream is = this.getClass().getResourceAsStream(fName); //we now have an input stream. Create a reader and read out //each character in the stream. System.out.println("---------- Input stream"); InputStreamReader isr = new InputStreamReader(is); char c; System.out.println("---------- Append string now"); while ((c = (char)isr.read()) != -1) { properties += c; } } catch (Exception e) { } return properties; } } I call my class constructor like this: Configuration config = new Configuration("/config.properties"); So in my class, "file" should have all the content of the config.properties file, and the fileName should have this value "/config.properties". But the "name" is null because the file cannot be found... I know this is the path of the file which should be different, but I don't know what i can change... The class is in the package com.mycompany.blackberry.utils Thank you!

  • How to convert an InputStream to a DataHandler?

    - by pcorey
    I'm working on a java web application in which files will be stored in a database. Originally we retrieved files already in the DB by simply calling getBytes on our result set: byte[] bytes = resultSet.getBytes(1); ... This byte array was then converted into a DataHandler using the obvious constructor: dataHandler=new DataHandler(bytes,"application/octet-stream"); This worked great until we started trying to store and retrieve larger files. Dumping the entire file contents into a byte array and then building a DataHandler out of that simply requires too much memory. My immediate idea is to retrieve a stream of the data in the database with getBinaryStream and somehow convert that InputStream into a DataHandler in a memory-efficient way. Unfortunately it doesn't seem like there's a direct way to convert an InputStream into a DataHandler. Another idea I've been playing with is reading chunks of data from the InputStream and writing them to the OutputStream of the DataHandler. But... I can't find a way to create an "empty" DataHandler that returns a non-null OutputStream when I call getOutputStream... Has anyone done this? I'd appreciate any help you can give me or leads in the right direction.

  • Parameterized Queries /Without/ using queries.

    - by Aren B
    I've got a bit of a poor situation here. I'm stuck working with commerce server, which doesn't do a whole lot of sanitization/parameterization. I'm trying to build up my queries to prevent SQL Injection, however some things like the searches / where clause on the search object need to be built up, and there's no parameterized interface. Basically, I cannot parameterize, however I was hoping to be able to use the same engine to BUILD my query text if possible. Is there a way to do this, aside from writing my own parameterizing engine which will probably still not be as good as parameterized queries? Update: Example The where clause has to be built up as a sql query where clause essentially: CatalogSearch search = /// Create Search object from commerce server search.WhereClause = string.Format("[cy_list_price] > {0} AND [Hide] is not NULL AND [DateOfIntroduction] BETWEEN '{1}' AND '{2}'", 12.99m, DateTime.Now.AddDays(-2), DateTime.Now); *Above Example is how you refine the search, however we've done some testing, this string is NOT SANITIZED. This is where my problem lies, because any of those inputs in the .Format could be user input, and while i can clean up my input from text-boxes easily, I'm going to miss edge cases, it's just the nature of things. I do not have the option here to use a parameterized query because Commerce Server has some insane backwards logic in how it handles the extensible set of fields (schema) & the free-text search words are pre-compiled somewhere. This means I cannot go directly to the sql tables What i'd /love/ to see is something along the lines of: SqlCommand cmd = new SqlCommand("[cy_list_price] > @MinPrice AND [DateOfIntroduction] BETWEEN @StartDate AND @EndDate"); cmd.Parameters.AddWithValue("@MinPrice", 12.99m); cmd.Parameters.AddWithValue("@StartDate", DateTime.Now.AddDays(-2)); cmd.Parameters.AddWithValue("@EndDate", DateTime.Now); CatalogSearch search = /// constructor search.WhereClause = cmd.ToSqlString();

  • Using HttpClient with SSL and certificates

    - by ChrisCM
    While I've been familiar with HTTPS and the concept of SSL, I have recently begun some development and found I am a little confused. The requirement was that I write a small Java application that runs on a machine attached to a scanner. When a document is scanned this is picked up and the file (usually PDF) sent over the internet to our application server that will then process it. I've written the application using Apache Commons libraries and HTTPClient. The second requirement was to connect over SSL, requiring a certificate. Following guidance on the HTTPclient page I am using AuthSSLProtocolSocketFactory from the contributions page. The constructor can take a keystore, keystore password, truststore and truststore password. As an initial test our DBA enabled SSL on one of our development webservers and provided me with a .p12 file which when I imported into IE allows me to connect successfully. I am a bit confused between keystores and truststores and what steps I need to take using the keytool. I tried importing the p12 into a keystore file but get the error: keytool error: java.lang.Exception: Input not an X.509 certificate I followed a suggestion of importing the p12 into Internet Explorer and exporting as a .cer which I can then successfully import into a keystore. When I supply this as a keystore argument of the AuthSSLProtocolSocketFactory I get a meaningless errror, but if I try it as a truststore it seems like it reads it fine but ultimately I get Caused by: javax.net.ssl.SSLHandshakeException: Received fatal alert: bad_certificate I am unsure if I have missed some steps, I am misunderstanding SSL and mutual authentication altogether or this is mis-configuration on the server side. Can anyone provide suggestions or point me towards resources that might help me figure this out please?

  • JNI: Long-object created with wrong value

    - by Torbjörn Eklund
    Hi! I am writing a c-jni function in Android, and I am having problems with creating a Long-object. I have succeeded in calling the constructor, but when I read the value of the object with longValue, I get the wrong result. jmethodID longConstructor; jmethodID longGetLongValue; jclass cls; jobject obj; // Create a object of type Long. cls = (*env)->FindClass(env,"java/lang/Long"); longConstructor = (*env)->GetMethodID(env,cls,"<init>","(J)V"); obj = (*env)->NewObject(env, cls, longConstructor, 4242); // Get the value by calling the function longValue. longGetLongValue= (*env)->GetMethodID(env,cls,"longValue","()J"); long return_long_value = (*env)->CallLongMethod(env, obj, longGetLongValue); // Log the result. LOGD("%li", return_long_value); I would expect that the above code would print 4242 in the log, however the value that is printed in the log is 1691768. Does anybody have an idea on why 4242 is not written in the log?

  • How to marshall non-string objects with JAXB and Spring

    - by lesula
    I was trying to follow this tutorial in order to create my own restful web-service using Spring framework. The client do a GET request to, let's say http://api.myapp/app/students and the server returns an xml version of the object classroom: @XmlRootElement(name = "class") public class Classroom { private String classId = null; private ArrayList<Student> students = null; public Classroom() { } public String getClassId() { return classId; } public void setClassId(String classId) { this.classId = classId; } @XmlElement(name="student") public ArrayList<Student> getStudents() { return students; } public void setStudents(ArrayList<Student> students) { this.students = students; } } The object Student is another bean containing only Strings. In my app-servlet.xml i copied this lines: <bean id="studentsView" class="org.springframework.web.servlet.view.xml.MarshallingView"> <constructor-arg ref="jaxbMarshaller" /> </bean> <!-- JAXB2 marshaller. Automagically turns beans into xml --> <bean id="jaxbMarshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller"> <property name="classesToBeBound"> <list> <value>com.spring.datasource.Classroom</value> <value>com.spring.datasource.Student</value> </list> </property> </bean> Now my question is: what if i wanted to insert some non-string objects as class variables? Let's say i want a tag containing the String version of an InetAddress, such as <inetAddress>192.168.1.1</inetAddress> How can i force JAXB to call the method inetAddress.toString() in such a way that it appears as a String in the xml? In the returned xml non-string objects are ignored!

  • Validation without ServiceLocator

    - by Dmitriy Nagirnyak
    Hi, I am getting back again and again to it thinking about the best way to perform validation on POCO objects that need access to some context (ISession in NH, IRepository for example). The only option I still can see is to use S*ervice Locator*, so my validation would look like: public User : ICanValidate { public User() {} // We need this constructor (so no context known) public virtual string Username { get; set; } public IEnumerable<ValidationError> Validate() { if (ServiceLocator.GetService<IUserRepository>().FindUserByUsername(Username) != null) yield return new ValidationError("Username", "User already exists.") } } I already use Inversion Of control and Dependency Injection and really don't like the ServiceLocator due to number of facts: Harder to maintain implicit dependencies. Harder to test the code. Potential threading issues. Explicit dependency only on the ServiceLocator. The code becomes harder to understand. Need to register the ServiceLocator interfaces during the testing. But on the other side, with plain POCO objects, I do not see any other way of performing the validation like above without ServiceLocator and only using IoC/DI. So the question would be: is there any way to use DI/IoC for the situation described above? Thanks, Dmitriy.

  • Moose read-only Attribute Traits and how to set them?

    - by Evan Carroll
    How do I set a Moose read only attribute trait? package AttrTrait; use Moose::Role; has 'ext' => ( isa => 'Str', is => 'ro' ); package Class; has 'foo' => ( isa => 'Str', is => 'ro', traits => [qw/AttrTrait/] ); package main; my $c = Class->new( foo => 'ok' ); $c->meta->get_attribute('foo')->ext('die') # ro attr trait What is the purpose of Read Only attribute traits if you can't set it in the constructor or in runtime? Is there something I'm missing in Moose::Meta::Attribute? Is there a way to set it using meta? $c->meta->get_attr('ext')->set_value('foo') # doesn't work either (attribute trait provided not class provided method)

  • Inconsistent get_class_methods vs method_exists when using UTF8 characters in PHP code

    - by coma
    I have this class in a UTF-8 encoded file called EnUTF8.Class.php: class EnUTF8 { public function ñññ() { return 'ñññ()'; } } and in another UTF-8 encoded file: require_once('EnUTF8.Class.php'); require_once('OneBuggy.Class.php'); $utf8 = new EnUTF8(); //$buggy = new OneBuggy(); echo (method_exists($utf8, 'ñññ')) ? 'ñññ() exists!' : 'ñññ() does not exist...'; echo "\n\n----------------------------------\n\n" print_r(get_class_methods($utf8)); echo "\n----------------------------------\n\n" echo $utf8->ñññ(); that produces the expected result: ñññ() exists! ---------------------------------- Array ( [0] => ñññ ) ---------------------------------- ñññ() but if... require_once('EnUTF8.Class.php'); require_once('OneBuggy.Class.php'); $utf8 = new EnUTF8(); $buggy = new OneBuggy(); echo (method_exists($utf8, 'ñññ')) ? 'ñññ() exists!' : 'ñññ() does not exist...'; echo "\n\n----------------------------------\n\n" print_r(get_class_methods($utf8)); echo "\n----------------------------------\n\n" echo $utf8->ñññ(); then the weirdness appears!!!: ñññ() does not exist! ---------------------------------- Array ( [0] => ñññ ) ---------------------------------- Fatal error: Call to undefined method EnUTF8::ñññ() in /var/www/test.php on line 16 Well, the thing is that OneBuggy.Class.php is UTF-8 encoded too and shares absolutly nothing with EnUTF8.Class.php so... where is the bug? UPDATED: Well, after a long debugging time I found this in OneBuggy.Class.php constructor: setlocale (LC_ALL, "es_ES@euro", "es_ES", "esp"); so I did... //setlocale (LC_ALL, "es_ES@euro", "es_ES", "esp"); and now it works but why?.

  • PHP XML Strategy: Parsing DOM to fill "Bean"

    - by Mike
    I have a question concerning a good strategy on how to fill a data "bean" with data inside an xml file. The bean might look like this: class Person { var $id; var $forename = ""; var $surname = ""; var $bio = new Biography(); } class Biography { var $url = ""; var $id; } the xml subtree containing the info might look like this: <root> <!-- some more parent elements before node(s) of interest --> <person> <name pre="forename"> Foo </name> <name pre="surname"> Bar </name> <id> 1254 </id> <biography> <url> http://www.someurl.com </url> <id> 5488 </id> </biography> </person> </root> At the moment, I have one approach using DOMDocument. A method iterates over the entries and fills the bean by "remembering" the last node. I think thats not a good approach. What I have in mind is something like preconstructing some xpath expression(s) and then iterate over the subtrees/nodeLists. Return an array containing the beans as defined above eventually. However, it seems not to be possible reusing a subtree /DOMNode as DOMXPath constructor parameter. Has anyone of you encountered such a problem?
