  • Create a nested list

    - by sico87
    How would I create a nested list, I currently have this public function getNav($cat,$subcat){ //gets all sub categories for a specific category if(!$this->checkValue($cat)) return false; //checks data $query = false; if($cat=='NULL'){ $sql = "SELECT itemID, title, parent, url, description, image FROM p_cat WHERE deleted = 0 AND parent is NULL ORDER BY position;"; $query = $this->db->query($sql) or die($this->db->error); }else{ //die($cat); $sql = "SET @parent = (SELECT c.itemID FROM p_cat c WHERE url = '".$this->sql($cat)."' AND deleted = 0); SELECT c1.itemID, c1.title, c1.parent, c1.url, c1.description, c1.image, (SELECT c2.url FROM p_cat c2 WHERE c2.itemID = c1.parent LIMIT 1) as parentUrl FROM p_cat c1 WHERE c1.deleted = 0 AND c1.parent = @parent ORDER BY c1.position;"; $query = $this->db->multi_query($sql) or die($this->db->error); $this->db->store_result(); $this->db->next_result(); $query = $this->db->store_result(); } return $query; } public function getNav($cat=false, $subcat=false){ //gets a list of all categories form this level, if $cat is false it returns top level nav if($cat==false || strtolower($cat)=='all-products') $cat='NULL'; $ds = $this->data->getNav($cat, $subcat); $nav = $ds ? $ds : false; $html = ''; //create html if($nav){ $html = '<ul>'; //var_dump($nav->fetch_assoc()); while($row = $nav->fetch_assoc()){ $url = isset($row['parentUrl']) ? $row['parentUrl'].'/'.$row['url'] : $row['url']; $current = $subcat==$row['url'] ?

  • C# - Sharing static data between multiple processes

    - by Murtaza Mandvi
    I have a WCF service (instantiated within a Console application on NetTCP), this service has static data (large volume) which gets instantiated on the load. I have multiple instances of this Console application running at once, and all of them are doing the same static data initialization , is there a way that I can have a single data source and share the data among processes so that each process does not have to consume large amount of memory?

  • Apache as Reverse Proxy for CouchDB

    - by Overflown
    I'm thinking of a web app that uses CouchDB extensively, to the point where there would be great gains from serving with the native erlang HTTP API as much as possible. Can you configure Apache as a reverse proxy to allow outside GETs to be proxied directly to CouchDB, whereas PUT/POST are sent to the application internal logic (for sanitation, authentication...)? Or is this unwise -- the CouchDB built-in authentication options just seem a little weak for a Web App. Thanks

  • Java: Finding objects in collections.

    - by Jake
    This problem occurs over and over. I have some complicated object, such as a Cat, which has many properties, such as age, favorite cat food, and so forth. A bunch of Cats are stored in a Java Collection, and I need to find all the Cats that are aged 3, or those whose favorite cat food is Whiskas. Surely, I can write a custom method that finds those Cats with a specific property, but this gets cumbersome with many properties; is there some generic way of doing this?

  • protect_from_forgery & Unobtrusive Javascript

    - by Matt Grande
    Hi all, I have some javascript making an ajax call in my Rails site: $.ajax({type: "PUT", url: url, data: { dummy: data }, complete: function(data) {}}); When Rails gets it, it throws back an ActionController::InvalidAuthenticityToken Error. I'd like to keep the protect_from_forgery stuff in there, if possible... But I'm at a loss for how can I pass the auth token from a javascript file? Can anyone help me out?

  • Using IOperationBehavior to supply a WCF parameter

    - by Chris Kemp
    This is my first step into the world of stackoverflow, so apologies if I cock anything up. I'm trying to create a WCF Operation which has a parameter that is not exposed to the outside world, but is instead automatically passed into the function. So the world sees this: int Add(int a, int b) But it is implemented as: int Add(object context, int a, int b) Then, the context gets supplied by the system at run-time. The example I'm working with is completely artificial, but mimics something that I'm looking into in a real-world scenario. I'm able to get close, but not quite the whole way there. First off, I created a simple method and wrote an application to confirm it works. It does. It returns a + b and writes the context as a string to my debug. Yay. [OperationContract] int Add(object context, int a, int b); I then wrote the following code: public class SupplyContextAttribute : Attribute, IOperationBehavior { public void Validate(OperationDescription operationDescription) { if (!operationDescription.Messages.Any(m => m.Body.Parts.First().Name == "context")) throw new FaultException("Parameter 'context' is missing."); } public void ApplyDispatchBehavior(OperationDescription operationDescription, DispatchOperation dispatchOperation) { dispatchOperation.Invoker = new SupplyContextInvoker(dispatchOperation.Invoker); } public void ApplyClientBehavior(OperationDescription operationDescription, ClientOperation clientOperation) { } public void AddBindingParameters(OperationDescription operationDescription, BindingParameterCollection bindingParameters) { // Remove the 'context' parameter from the inbound message operationDescription.Messages[0].Body.Parts.RemoveAt(0); } } public class SupplyContextInvoker : IOperationInvoker { readonly IOperationInvoker _invoker; public SupplyContextInvoker(IOperationInvoker invoker) { _invoker = invoker; } public object[] AllocateInputs() { return _invoker.AllocateInputs().Skip(1).ToArray(); } private object[] IntroduceContext(object[] inputs) { return new[] { "MyContext" }.Concat(inputs).ToArray(); } public object Invoke(object instance, object[] inputs, out object[] outputs) { return _invoker.Invoke(instance, IntroduceContext(inputs), out outputs); } public IAsyncResult InvokeBegin(object instance, object[] inputs, AsyncCallback callback, object state) { return _invoker.InvokeBegin(instance, IntroduceContext(inputs), callback, state); } public object InvokeEnd(object instance, out object[] outputs, IAsyncResult result) { return _invoker.InvokeEnd(instance, out outputs, result); } public bool IsSynchronous { get { return _invoker.IsSynchronous; } } } And my WCF operation now looks like this: [OperationContract, SupplyContext] int Amend(object context, int a, int b); My updated references no longer show the 'context' parameter, which is exactly what I want. The trouble is that whenver I run the code, it gets past the AllocateInputs and then throws an Index was outside the bounds of the Array. error somewhere in the WCF guts. I've tried other things, and I find that I can successfully change the type of the parameter and rename it and have my code work. But the moment I remove the parameter it falls over. Can anyone give me some idea of how to get this to work (or if it can be done at all).

  • What's a good PHP Active Record library?

    - by Luca Matteis
    I've been using CodeIgniter for some quite time, and I've been extremely happy with its Active Record stuff. It's great to query the database with it. Recently I've started a new project and I can't use such a framework anymore. Is there a simple PHP Active Record library that does its job and gets out of the way (similar to CodeIgniter's version)?

  • Delayed responses for cURL SSL PUTs/POSTs (php) (NSS vs OpenSSL)

    - by Yarin
    I have two Fedora-based apache webservers making the same SSL PUT/POST calls with php/cURL. One works fine, but with the other the call succeeds but takes a VERY long time to return a response (~10 min). (GETs don't seem affected) The working server's cURL uses OpenSSL for SSL, while the non-working version uses a later version of cURL that uses NSS for SSL I know nothing about SSL implementations or their effect on cURL. What would cause such a significant delay in SSL PUT/POST responses? Any suggestions appreciated- Thanks--

  • When is the onPreExecute called on an AsyncTask running parallely or concurrently?

    - by Debarshi Dutta
    I am using Android HoneyComb.I need to execute some tasks parallely and I am using AsyncTask's public final AsyncTask executeOnExecutor (Executor exec, Params... params) method.In each separate thread I am computing some values and I need to store then in an ArrayList.I must then sort all the values in the arrayList and then display it in the UI.Now my question is if one of the thread gets completed earlier than the other then will it immediately call the onPostExecute method or onPostExecute method will be called after all the background threads have been completed?MY program implementation depends on what occurs here.

    - by drax
    Hi, I have strange problem with sharepoint and ajax functionality. We have an UpdatePanel placed inside webpart. When partial postback occurs, page title gets missing. We have found that temporary partial solution is to write title element into one line and not use any spaces or controls inside it..not even a literal control. But we need some way to provide sommon title for all pages, so title would look like this: My default title - Current page title Any ideas how to solve this?

  • Can't append space at end of NSString

    - by Sam V
    I have a UITextView in which I want the initial value to be "@username " (notice the space after the username). This way the user can start typing right away without having to tap space. So I do: textView.text = [NSString stringWithFormat:@"@%@ ", username]; But it seems like it's impossible to have an NSString ending with a space (it always gets stripped out). Am I correct? Is there any workaround for this?

  • 'Locale' configuration and its relationship with Windows API

    - by The Kaykay
    Can the locale configuration of a system OR the keyboard type configuration of that system in anyway affect which API is called at the Kernel level? To be specific, if a program is invoking 'CreateFile()' API then the windows API documentation says that the call gets delegated to either CreateFileA or CreateFileW. If that program is being run on a system present in China with a Chinese Keyboard then which of the two functions will be called?
