  • CakePHP delete() function is not working

    - by Logic Artist
    Hello, Im just cracking open cakePHP (v1.3.2). I set it up on my local wamp server, seems to work fine except the delete() function doesn't work. I'm following their blog tutorial exactly, its as simple as it can be so I don't understand why its not working. Heres the function in my PostsController class: function delete($id = NULL) { $this->Post->delete($id); $this->Session->setFlash('The post with id: '.$id.' has been deleted.'); $this->redirect(array('action'=>'index')); } The "Delete" link's url looks like http://localhost/posts/delete/id:1 (where the id number matches the particular post, obviously). It redirects and sets the flash message, however there is no number where $id should be in the message, and the post isn't deleted. It seems the proper id is passed through the url, but I don't think it is getting into the function. I dont get it. Any ideas???

  • How to match parameter names in an expression?

    - by burak ozdogan
    Hi, I have a set of expressions representing some formula with some parameters inside. Like: [parameter1] * [parameter2] * [multiplier] And many others like this. I want to use a regular expression so that I can get a list of strings (List<string>) which will have the following inside: [paramter1] [paramter2] [multiplier] I am not using regular expressions so often; if you have already used something like this I would appreciate if you can share. Thanks!

  • Abstract class get parameter from implementing subclass?

    - by soren.qvist
    I'm wondering if there is way to do this without breaking encapsulation, I want the abstract class to rely on parameters defined in the implementing subclass. Like so: public abstract class Parent { private int size; private List<String> someList; public Parent() { size = getSize(); someList = new ArrayList<String>(size); } public abstract int getSize(); } public class Child extends Parent { @Override public int getSize() { return 5; } } Is this ugly? Is there a better way? And perhaps more importantly, is this even a good idea?

  • Why PHP Error: Call to a member function set_prefix() on a non-object

    - by Rebol Tutorial
    I got this error Fatal error: Call to a member function set_prefix() on a non-object in /home/reboltutorial/reboltutorial.com/wp-settings.php on line 254 line 254 contains: $prefix = $wpdb->set_prefix($table_prefix); // set up global tables This occurs if I try to call index_wordpress() instead of calling these two lines define('WP_USE_THEMES', true); require('./wp-blog-header.php'); so this doesn't work: <?php function index_wordpress() { define('WP_USE_THEMES', true); require('./wp-blog-header.php'); } ?> <?php if(!function_exists('apache_request_headers')) { function apache_request_headers() { $headers = array(); foreach($_SERVER as $key => $value) { if(substr($key, 0, 5) == 'HTTP_') { $headers[str_replace(' ', '-', ucwords(str_replace('_', ' ', strtolower(substr($key, 5)))))] = $value; } } return $headers; } } function getCurrentPageUrl() { $pageURL = 'http'; if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";} $pageURL .= "://"; if ($_SERVER["SERVER_PORT"] != "80") { $pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"]; } else { $pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"]; } return $pageURL; } $a = apache_request_headers(); $pos = strrpos($a["User-Agent"], "REBOL"); if ($pos === false) { index_wordpress(); } else { if ($_SERVER['REMOTE_ADDR'] != "69.163.203.14") { $command= './cgi-bin/index.cgi '.

  • Force to reimplement a static function in inherit classes

    - by pacopepe
    Hi, I have a program in C++ with plugins (dynamic libs). In the main program, I want to execute a static function to check if i can create a object of this type. An example without dynamic libs (aren't neccesary to understand the problem): #include "libs/parent.h" #include "libs/one.h" #include "libs/two.h" int main(int argc, char * argv[]) { Parent obj; if (One.match(argv[1])) { obj = new One(); else if (Two.match(argv[1])) { obj = new Two(); } Now, i have a interface class named Parent. All plugins inherit from this class. Ideally, I have a virtual static function in Parent named match, and all the plugins need to reimplement this function. The problem with this code is that i can't do a static virtual function in C++, so i don't know how to solve the problem. Sorry for mi english, i did my best

  • Wrap Sub as Function for use in Lambda

    - by Luhmann
    I have a problem with VB and Moq. I need to call a verify on a Sub. Like so: logger.Verify(Function(x) x.Log, Times.AtLeastOnce) And my logger looks like this: Public Interface ILogger Sub Log() End Interface But with VB this is not possible, because the Log method is a Sub, and thereby does not produce a value. I don't want to change the method to be a function. Whats the cleanest way of working around this limitation and is there any way to wrap the Sub as a Function like the below? logger.Verify(Function(x) ToFunc(AddressOf x.Log)) I have tried this, but i get: Lambda Parameter not in scope

  • Accessing loop iteration in a sub-function?

    - by DisgruntledGoat
    I'm using the Google Maps API to plot several points on a map. However, in the click event function below, i is always set to 4, i.e. its value after iterating the loop: // note these are actual addresses in the real page var addresses = new Array( "addr 1", "addr 2", "addr 3", "addr 4" ); for (var i = 0; i < addresses.length; i++) { geocoder.getLatLng(addresses[i], function(point) { if (point) { var marker = new GMarker(point); map.addOverlay(marker); map.setCenter(point, 13); GEvent.addListener(marker, "click", function() { // here, i=4 marker.openInfoWindowHtml("Address: <b>" + addresses[i] + "</b>"); }); } }); } So when the marker displays it's using addresses[4] which is undefined. How do I pass the correct value of i to the function?

  • “Function” calling inside store procedure

    - by idimba
    Hi, I have a big store procedure, that contains a lot of INSERTs. There're many INSERTS that almost identical - they're different by some parameter(s) (all INSERTs to the same table) Is there a way to create a function/method, to which I'll pass the above parameter(s) and the function/method will generate concrete INSERT's? Thanks

  • Adding a wrapper to an overloaded function

    - by Cev
    Say you had a timestamp function and then wanted to create a new function to combine your timestamp and Console.WriteLine(), e.g. public static void Write(string msg) { WriteTimeStamp(); Console.WriteLine( msg ); } But the WriteLine() method has 18 or so overloads, which will not be reflected in the signature of the wrapper function. How would you have the wrapper take non-strings and pass them on to WriteLine()?

  • Using java provided parameters into xpath function while applying xslt transformation

    - by filmac
    I'm working at a java application that performs some xslt transformation. I would like to match nodes into the xslt document, using a parameter provided by java. Which is the right way to do something like: <xsl:template match="//m:properties/*[contains($pattern,name())]"> because when I launch my application, it claims it's not able to compile the stylesheet, since pattern is not defined but I'm setting it using the setParameter method and I was able to use another parameter defined in the same way but in a different context. Thanks in advance Fil

  • Java - How to pass a Generic parameter as Class<T> to a constructor

    - by Joe Almore
    I have a problem here that still cannot solve, the thing is I have this abstract class: public abstract class AbstractBean<T> { private Class<T> entityClass; public AbstractBean(Class<T> entityClass) { this.entityClass = entityClass; }... Now I have another class that inherits this abstract: @Stateless @LocalBean public class BasicUserBean<T extends BasicUser> extends AbstractBean<T> { private Class<T> user; public BasicUserBean() { super(user); // Error: cannot reference user before supertype contructor has been called. } My question is how can I make this to work?, I am trying to make the class BasicUserBean inheritable, so if I have class PersonBean which inherits BasicUserBean then I could set in the Generic the entity Person which also inherits the entity BasicUser. And it will end up being: @Stateless @LocalBean public class PersonBean extends BasicUserBean<Person> { public PersonBean() { super(Person.class); } ... I just want to inherit the basic functionality from BasicUserBean to all descendants, so I do not have to repeat the same code among all descendants. Thanks!.

  • Haskell: foldl' accumulator parameter

    - by Clinton
    I've been asking a few questions about strictness, but I think I've missed the mark before. Hopefully this is more precise. Lets say we have: n = 1000000 f z = foldl' (\(x1, x2) y -> (x1 + y, y - x2)) z [1..n] Without changing f, what should I set z = ... So that f z does not overflow the stack? (i.e. runs in constant space regardless of the size of n) Its okay if the answer requires GHC extensions. My first thought is to define: g (a1, a2) = (!a1, !a2) and then z = g (0, 0) But I don't think g is valid Haskell.

    Hello, I'm building a shopping cart and I would like to use a JavaScript function to validate user input when entering the quantity value in the quantity text input.

I know that I can apply this function using onKeyUp event and also I found isNaN() function, but it returns true even for floats (which is not ok). Can you guys help me out with this one? Thanks.
