  • JQuery - Pass variables to PHP script via AJAX call and then display file

    - by hfidgen
    Hiya, I'm trying to generate Outlook event files for my events, doing so on the fly as and when someone requests it by pressing a link on the page. Here's what i've got so far, but I can't find out how to get the browser to download the content which is returned. I know how I could do this if I sent everything via _GET, but I'd prefer to do it via _POST, hence I'm going down this route.. Any thoughts? Thanks! HTML / Javascript <script> $(function() { $(".button").click(function() { // validate and process form // first hide any error messages var start = $("input#start").val(); var end = $("input#end").val(); var dataString = 'start='+ start + '&end=' + end; $.ajax({ type: "POST", url: "/calendar.php", data: dataString, success: function(data) { //Need to return the file contents somehow! } }); return false; }); }); </script> <form name="calendar" method="post" action=""> <input type="hidden" name="start" id="start" value="<?php echo $start; ?>" /> <input type="hidden" name="end" id="end" value="<?php echo $end; ?>" /> <input type="submit" name="submit" class="button" id="submit_btn" value="Outlook" /> </fieldset> </form> PHP File <?php if (isset($_POST['start'])) { $start = $_POST['start']; $end = $_POST['end']; $c = header("Content-Type: text/Calendar"); $c .= header("Content-Disposition: inline; filename=calendar.ics"); $c .= "BEGIN:VCALENDAR\n"; $c .= "VERSION:2.0\n"; $c .= "PRODID:-//xxxyyyy//NONSGML //EN\n"; $c .= "METHOD:REQUEST\n"; // requied by Outlook $c .= "BEGIN:VEVENT\n"; $c .= "UID:". $start . $end ."-" . "-xxxxyyyy.com\n"; // required by Outlook $c .= "DTSTAMP:".date('Ymd').'T'.date('His')."\n"; // required by Outlook $c .= "DTSTART:20080413T000000\n"; $c .= "SUMMARY:" . "\n"; $c .= "DESCRIPTION:" . "\n"; $c .= "END:VEVENT\n"; $c .= "END:VCALENDAR\n"; echo $c; } else { echo "Sorry you can't access this page directly"; } ?>

    I am developing a flex java - spring web app and have set up the business logic using hibernate. I want to maintain sessions so that when the user logs in , i can track the logged in user to display information that is related to the username. I want to do this using spring if possible and wondered if anyone could redirect me to a tutorial or even explain the method to which this is achieved , or if it is hard to achieve. Thanks Chris

  • User Defined Exceptions with JMX

    - by Daniel
    I have exposed methods for remote management in my application server using JMX by creating an MXBean interface, and a class to implement it. Included in this interface are operations for setting attributes on my server, and for getting the current value of attributes. For example, take the following methods: public interface WordManagerMXBean { public void addWord(String word); public WordsObject getWords(); public void removeWord(String word); } The WordsObject is a custom, serializable class used to retrieve data about the state of the server. Then I also have a WordManager class that implements the above interface. I then create a JMX agent to manage my resource: MBeanServer mbs = ManagementFactory.getPlatformMBeanServer(); ObjectName wordManagerName = new ObjectName("com.example:type=WordManager"); mbs.registerMBean(wordManager, wordManagerName); I have created a client that invokes these methods, and this works as expected. However, I would like to extend this current configuration by adding user defined exceptions that can be sent back to my client. So I would like to change my interface to something like this: public interface WordManagerMXBean { public void addWord(String word) throws WordAlreadyExistsException; public WordsObject getWords(); public void removeWord(String word); } My WordAlreadyExistsException looks like this: public class WordAlreadyExistsException extends Exception implements Serializable { private static final long serialVersionUID = -9095552123119275304L; public WordAlreadyExistsException() { super(); } } When I call the addWord() method in my client, I would like to get back a WordAlreadyExistsException if the word already exists. However, when I do this, I get an error like this: java.rmi.UnmarshalException: Error unmarshaling return; nested exception is: java.lang.ClassNotFoundException: com.example.WordAlreadyExistsException The WordAlreadyExistsException, the WordsObject and the WordManagerMXBean interface are all in a single jar file that is available to both the client and the server. If I call the getWords() method, the client has no difficulty handling the WordsObject. However, if a user defined exception, like the one above, is thrown, then the client gives the error shown above. Is it possible to configure JMX to handle this exception correctly in the client? Following some searching, I noticed that there is an MBeanException class that is used to wrap exceptions. I'm not sure if this wrapping is performed by the agent automatically, or if I'm supposed to do the wrapping myself. I tried both, but in either case I get the same error on the client. I have also tried this with both checked and unchecked exceptions, again the same error occurs. One solution to this is to simply pass back the error string inside a generic error, as all of the standard java exceptions work. But I'd prefer to get back the actual exception for processing by the client. Is it possible to handle user defined exceptions in JMX? If so, any ideas how?

  • Updating UISearchDisplayController with Core Data results using GCD

    - by Brian Halpin
    I'm having trouble displaying the results from Core Data in my UISearchDisplayController when I implement GCD. Without it, it works, but obviously blocks the UI. In my SearchTableViewController I have the following two methods: - (BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString { // Tell the table data source to reload when text changes [self filterContentForSearchText:searchString]; // Return YES to cause the search result table view to be reloaded. return YES; } // Update the filtered array based on the search text -(void)filterContentForSearchText:(NSString*)searchText { // Remove all objects from the filtered search array [self.filteredLocationsArray removeAllObjects]; NSPredicate *predicate = [CoreDataMaster predicateForLocationUsingSearchText:@"Limerick"]; CoreDataMaster *coreDataMaster = [[CoreDataMaster alloc] init]; // Filter the array using NSPredicate self.filteredLocationsArray = [NSMutableArray arrayWithArray: [coreDataMaster fetchResultsFromCoreDataEntity:@"City" UsingPredicate:predicate]]; } You can probably guess that my problem is with returning the array from [coreDataMaster fetchResultsFromCoreDataEntity]. Below is the method: - (NSArray *)fetchResultsFromCoreDataEntity:(NSString *)entity UsingPredicate:(NSPredicate *)predicate { NSMutableArray *fetchedResults = [[NSMutableArray alloc] init]; dispatch_queue_t coreDataQueue = dispatch_queue_create("com.coredata.queue", DISPATCH_QUEUE_SERIAL); dispatch_async(coreDataQueue, ^{ NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; NSEntityDescription *entityDescription = [NSEntityDescription entityForName:entity inManagedObjectContext:self.managedObjectContext]; NSSortDescriptor *nameSort = [[NSSortDescriptor alloc] initWithKey:@"name" ascending:YES]; NSArray *sortDescriptors = [NSArray arrayWithObjects:nameSort, nil]; [fetchRequest setEntity:entityDescription]; [fetchRequest setSortDescriptors:sortDescriptors]; // Check if predicate is set if (predicate) { [fetchRequest setPredicate:predicate]; } NSError *error = nil; NSArray *fetchedManagedObjects = [self.managedObjectContext executeFetchRequest:fetchRequest error:&error]; for (City *city in fetchedManagedObjects) { [fetchedResults addObject:city]; } NSDictionary *userInfo = [NSDictionary dictionaryWithObject:[NSArray arrayWithArray:fetchedResults] forKey:@"results"]; [[NSNotificationCenter defaultCenter] postNotificationName:@"fetchResultsComplete" object:nil userInfo:userInfo]; }); return [NSArray arrayWithArray:fetchedResults]; } So the thread hasn't finished executing by the time it returns the results to self.filteredLocationsArray. I've tried added a NSNotification which passes the NSDictionary to this method: - (void)updateSearchResults:(NSNotification *)notification { NSDictionary *userInfo = notification.userInfo; NSArray *array = [userInfo objectForKey:@"results"]; self.filteredLocationsArray = [NSMutableArray arrayWithArray:array]; [self.tableView reloadData]; } I've also tried refreshing the searchViewController like [self.searchDisplayController.searchResultsTableView reloadData]; but to no avail. I'd really appreciate it if someone could point me in the right direction and show me where I might be going wrong. Thanks

  • Ruby on Rails: Can I do a "link_to" to call a create action?

    - by sjsc
    How would I correctly call the create action from a link_to? Here's the create action: def create recipe = Recipe.create(:name => "French fries") redirect_to recipe end For example, I thought something like this might work: <%= link_to "Create a default recipe", recipe_path, :method => :post %> I'm not sure if that's a recommended (or even correct) way to do it. Any idea?

  • Writing direct to disk with php

    - by Jurander
    I would like to create an upload script that doesn't fall under the php upload limit. There might be an occasion where I need to upload a 2GB, or larger file and I don't want to have to change the whole server execution to above 32MB. Is there a way to write direct to disk from php? What method might you propose someone would use to accomplish this? I have read around stack overflow but haven't quite found what I am looking to do.

  • A popup button with a static image (Cocoa OSX)

    - by Michael Minerva
    I am trying to make a popup button that always displays a + as its image and when you click on it, a context menu pops up that will allow you to decide what type of object you want to add. Is there anyway to do this using an NSPopupButton? I saw in the specs for NSPopupButotn that the method SetImage has no effect so it seems that this is likely not going to work using this class. Is this correct?

  • CodePage ID to CodaPage name: GetEncoding equivalent in Delphi?

    - by Steve
    Hello all, I'm looking for a Win32 equivalent of the .Net Encoding.GetEncoding Method to be used in Delphi7. What I would like to achieve is to convert a Codepage ID (ie.: 28592) to a Codapage name (iso-8859-2 in this case). I've found a Win32 function called GetCPInfoEx, but that returns a long CodePage name, and I need the short one, like the ones listed on this page: (see Name column) http://msdn.microsoft.com/en-us/library/system.text.encoding.aspx Thank you!

  • Enable UIBarButtonItem if multiple UITextFields are all populated

    - by CrystalSkull
    I have 3 UITextFields in a grouped UITableView and am trying to figure out the correct logic to only have my 'Save' UIBarButtonItem enabled when none of the UITextFields are empty. I'm currently using the - (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string UITextField delegate method to detect changes to the field character by character, but it is providing inconsistent results. Any ideas?

  • How to keep alive an HttpModule (a.k.a register it as a singleton)

    - by Micah
    I pretty sure I've seen this somewhere but I can't seem to find it anywhere. I have an HttpModule that can be used across multiple requests. In other words instead of creating a new instance of the Module on every request it only ever needs to create it once. Does this ring a bell to anyone? If so, what's the method for configuring to work this way?

  • How to insert Flash without JavaScript in the most compatible but valid way?

    - by Andreas Gohr
    I'm looking for a way to embed Flash into a XHTML Transitional page that does not rely on enabled JavaScript, which validates and that works across all major Browsers including IE6. So far I'm using this solution which seems to work just fine: http://latrine.dgx.cz/how-to-correctly-insert-a-flash-into-xhtml#toc-final-solution However, when this method is used in an RSS Feed it seems that Feedburner and Google Reader at least (maybe other feed readers, too) strip the whole object tags and only leave the alternative content. Any suggestions how to improve this?

  • Can IMAPI2 burn files with the size > 4Gb?

    - by Sergey Skoblikov
    IMAPI2 interface IFileSystem uses COM IStream interfaces to represent file data. There is AddTree method that adds specified directory contents to IFileSystem. So AddTree must create IStream's in the process. I wonder what implementation of IStream it uses? If it uses the standard OLE implementation than we have a nasty problem because OLE streams doesn't support files bigger than 4Gb. Can anyone shed some light on this issue?

  • Rails - Accessing model class methods from within ActiveRecord model

    - by aaronrussell
    I have a simple standalone model that doesn't inherit from ActiveRecord or anything else, called SmsSender. As the name suggests, it delivers text messages to an SMS gateway. I also have an ActiveRecord model called SmsMessage which has an instance method called deliver: def deliver SmsSender.deliver_message(self) self.update_attributes :status => "Sent" end The above is returning uninitialized constant SmsSender. I'm sure this is dead simple, but how can I access the SmsSender class from within my model?
