  • PHP Form Validation Regular Expression, no symbols or numbers

    - by MrEnder
    Ok I am trying to get the users First Name the form gets their name perfectly fine and posts it into a variable. Now I am trying to do error checking else if(!preg_match("/^[\w-]+$/", $firstNameSignup)) { $firstNameSignupError = "Your first name cannot contain numbers or symbols, you entered " . $firstNameSignup; $firstNameSignup = ""; } I tried the above code and it does not like me but my if statement if(!isset($firstNameSignup) || $firstNameSignup == "") { $firstNameSignupError = "You must enter your first name"; } works fine so I know that the error is in that else if statement... most likely in my regular expression any help??? I'm totally at a loss (really new to PHP and regular expressions) Thanks Shelby

  • Unable to view values of variables while debugging

    - by RexM
    I'm trying to debug portions of the current application I'm working on, however when I try and check the value of a property/variable I get the error: Cannot evaluate expression because a thread is stopped at a point where garbage collection is impossible, possibly because the code is optimized. This is just a regular ASP.NET project. In some portions of the application I can view the properties and variables perfectly fine. I haven't figured out what's different about the blocks of code that I can and can not see the values of the variables in.

  • Control within ascx is null when ascx is added from codebehind

    - by Snoop Dogg
    I am having difficulties how to construct my question, but if I have to put it simply the situation is that I have categories of products. I have an aspx with a repeater on the left that lists the categories. And I want the products to be listed on the right. Category number is variable so I made an ascx with a DataList in it. When I try to do foreach category, ascx = new ascx(); then the DataList within this ascx control is null. ps: what I want to do is to preload all the products (thre is not much) and hide the divs and fadein fadeout them using jQuery when a category div is clicked. rightnow it is using jQuery.load(); and I don't like how the images load, cuz they download from top to bottom. Progressive gifs alsdo not an option. site demo is here http://techlipse.net/test/ledart Thanks a lot in advance...

  • How do I Resolve dependancies that rely on transient context data using castle windsor?

    - by Dan Ryan
    I have a WCF service application that uses a component called EnvironmentConfiguration that holds configuration information for my application. I am converting this service so that it can be used by different applications that have different configuration requirements. I want to identify the configuration to use by allowing an additional parameter to be passed to the service call i.e. public void DoSomething(string originalParameter, string callingApplication) What is the recommended way to alter the behaviour of the EnvironmentConfiguration class based on the transient data (callingApplication) without having to pass the callingApplication variable to all the component methods that need configuration information?

  • Cannot populate form with ajax and populate jquery plugin

    - by Azriel_
    I'm trying to populate a form with jquery's populate plugin, but using $.ajax The idea is to retrieve data from my database according to the id in the links (ex of link: get_result_edit.php?id=34), reformulate it to json, return it to my page and fill up the form up with the populate plugin. But somehow i cannot get it to work. Any ideas: here's the code: $('a').click(function(){ $('#updatediv').hide('slow'); $.ajax({ type: "GET", url: "get_result_edit.php", success: function(data) { var $response=$(data); $('#form1').populate($response); } }); $('#updatediv').fadeIn('slow'); return false; whilst the php file states as follow: <?php $conn = new mysqli('localhost', 'XXXX', 'XXXXX', 'XXXXX'); @$query = 'Select * FROM news WHERE id ="'.$_GET['id'].'"'; $stmt = $conn->query($query) or die ($mysql->error()); if ($stmt) { $results = $stmt->fetch_object(); // get database data $json = json_encode($results); // convert to JSON format echo $json; } ?> Now first thing is that the mysql returns a null in this way: is there something wrong with he declaration of the sql statement in the $_GET part? Second is that even if i put a specific record to bring up, populate doesn't populate. Update: I changed the populate library with the one called "PHP jQuery helper functions" and the difference is that finally it says something. finally i get an error saying NO SUCH ELEMENT AS i wen into the library to have a look and up comes the following function function populateFormElement(form, name, value) { // check that the named element exists in the form var name = name; // handle non-php naming var element = form[name]; if(element == undefined) { debug('No such element as ' + name); return false; } // debug options if(options.debug) { _populate.elements.push(element); } } Now looking at it one can see that it should print out also the name, but its not printing it out. so i'm guessing that retrieving the name form the json is not working correctly. Link is at http://www.ocdmonline.org/michael/edit%5Fnews.php with username: Testing and pass:test123 Any ideas?

  • Why is my NSMutableArray returning nill?

    - by lampShade
    I have a very simple task: add the contents of a textField to an NSMutableArray.The Problem is the array is returning nill. I believe that it has something to do with the fact that the array I'm using is declared as an instance variable. /* IBOutlet NSTextField *textField; IBOutlet NSTabView *tableView; IBOutlet NSButton *button; NSMutableArray *myArray; */ #import "AppController.h" @implementation AppController -(IBAction)addNewItem:(id)sender { NSString *string = [textField stringValue]; NSLog(@"%@",string); [myArray addObject:string]; NSLog(@"%d",[myArray count]);//this outputs 0 why is that? }

  • How to save http referer in rails

    - by TenJack
    I'm trying to save the site that a user came from when they sign up. Right now I have a before_filter in my ApplicationController: before_filter :save_referer def save_referer unless is_logged_in? session['referer'] = request.env["HTTP_REFERER"] unless session['referer'] end end Then when a user is created, it checks this session variable and sets it to nil. Sometimes this does not work and I'm worried there might be some unintended things happening with using session like this. Does anyone have a better way? Or some input perhaps? EDIT: This is the logic I am using to save the referer: def create @user = User.new(params[:user]) if @user.save_with(session[:referer]) .... end User def save_with(referer) self.referer = referer unless referer == "null" self.save end Is there any reason why this should not work?

  • How can I enable Pascal casing by default when using Jackson JSON in Spring MVC?

    - by bhilstrom
    I have a project that uses Spring MVC to create and handle multiple REST endpoints. I'm currently working on using Jackson to automatically handle the seralization/deserialization of JSON using the @RequestBody and @ResponseBody annotations. I have gotten Jackson working, so I've got a starting point. My problem is that our old serialization was done manually and used Pascal casing instead of Camel casing ("MyVariable" instead of "myVariable"), and Jackson does Camel casing by default. I know that I can manually change the name for a variable using @JsonProperty. That being said, I do not consider adding "@JsonProperty" to all of my variables to be a viable long-term solution. Is there a way to make Jackson use Pascal casing when serializing and deserializing other than using the @JsonProperty annotation?

  • Age verification forms and crawlers

    - by user333763
    I have created a website about some beer brand and had to include age verification page. The verification script is written in PHP and uses sessions to store verification variable. The script works the way that no matter form which link you will try to enter the website it will take you to the verification page first. The verification is very simple. There are 2 button: "I'm under 21" and "I'm over 21". If you click the latter, you can browse the website. After some time I discovered that the web crawlers are not able to get past verification page. I checked the website in Google webmaster tools and the only text content scanned was from the verification page. I read somewhere that crawlers are not able to submit form buttons, is it true? Considering the fact that age verification pages are useless anyways, maybe I should just leave it as a starting page but don't forbid going around it, e.g. from links to the subpages?

  • Unselected UIPickerView value

    - by morticae
    According to the documentation, if a UIPickerView has no selected value, the expected return from selectedRowInComponent: should be: "A zero-indexed number identifying the selected row, or -1 if no row is selected." However, if I check the value the very line after initializing one, its value is 0. Even if I then manually set it to -1, it still returns 0. I would like to be able to detect whether the user has chosen a value yet or not, without recording it in a local variable. Is this possible? example: UIPickerView *picker = [[UIPickerView alloc] initWithFrame:CGRectMake(0.0, 46.0, 320.0, 216.0)]; [picker selectRow:-1 inComponent:0 animated:NO]; NSLog(@"SELECTED %d", [picker selectedRowInComponent:0]); expected output: SELECTED -1 actual output: SELECTED 0

  • How to set AeDebug to get a minidump with the name of the process ?

    - by JC Martin
    I have to perform some post mortem debugging on a C++ project. Known way to perform is to set the cdb debugger as a minidump generator and to process the dumps collects afterwards. I read nearly the whole web and I didn't find a solution to produce a minidump with the name of the process that has crashed Is there a way to set AeDebug\Debugger registry variable in such a manner that cdb generates a dump file with the name of the process ? When I encapsulate the call to cdb.exe in a batch file, it starts well but stays blocked on the symbol searching. I must perform a Ctrl+C in order to stop the batch, then the minidump, with the correct process name, is created... but of course I can't set up such a thing in an unattended production environment... Has anybody done that before ?

  • Ajax method within a added method in jQuery validator

    - by nikospkrk
    Hi, I'm kind of stuck with this pretty simple (I'm sure) jQuery/Javascript issue. Here's the code : jQuery.validator.addMethod("emailExists", function(value, element, param) { var email = value || ''; var valid = 0; $.ajax({ type: "POST", url: param, data: "email=" + email, success: function(msg) { if (msg != '' && msg) { valid = 0; } else { valid = 1; } } }); return valid; }, "* Email address already registered, please login."); This function is called where a user type his email address in a registration form, and everything seems to work perfectly, except that my valid variable returned isn't updated, whereas when I use an alert box it is properly done! It looks like it return the value before the AJAX is done, any idea? Cheers, Nicolas.

  • Using Parallel Extensions with ThreadStatic attribute. Could it leak memory?

    - by the-locster
    I'm using Parallel Extensions fairly heavily and I've just now encountered a case where using thread locla storrage might be sensible to allow re-use of objects by worker threads. As such I was lookign at the ThreadStatic attribute which marks a static field/variable as having a unique value per thread. It seems to me that it would be unwise to use PE with the ThreadStatic attribute without any guarantee of thread re-use by PE. That is, if threads are created and destroyed to some degree would the variables (and thus objects they point to) remain in thread local storage for some indeterminate amount of time, thus causing a memory leak? Or perhaps the thread storage is tied to the threads and disposed of when the threads are disposed? But then you still potentially have threads in a pool that are longed lived and that accumulate thread local storage from various pieces of code the threads are used for. Is there a better approach to obtaining thread local storage with PE? Thankyou.

  • EJB3 Caching Instance Variables

    - by Justin
    Hi, I've noticed some strange code on a project I am working on - its a SLSB EJB3, and it uses a private instance variable to maintain a cache of data (it even calls it dataCache or something), with a getter/setter. For EJB2 and bellow, this was a typical EJB antipattern - SLSBs are not meant to retain state in between invocations, theres no guarantee you'll see the same data on a subsequent invocation. One of my colleagues said maybe its ok in EJB3 (we don't have much EJB3 experience), but still, its a Stateless Session Bean - why is it trying to maintain state, this doesn't make sense. Can anyone confirm if this is still a bad idea in EJB3 land, or if somehow it is ok? Thanks if you can help, Justin

  • Django comparing model instances for equality

    - by orokusaki
    I understand that, with a singleton situation, you can perform such an operation as: spam == eggs and if spam and eggs are instances of the same class with all the same attribute values, it will return True. In a Django model, this is natural because two separate instances of a model won't ever be the same unless they have the same .pk value. The problem with this is that if a reference to an instance has attributes that have been updated by middleware somewhere along the way and it hasn't been saved, and you're trying to it to another variable holding a reference to an instance of the same model, it will return False of course because they have different values for some of the attributes. Obviously I don't need something like a singleton , but I'm wondering if there some official Djangonic (ha, a new word) method for checking this, or if I should simply check that the .pk value is the same with: spam.pk == eggs.pk I'm sorry if this was a huge waste of time, but it just seems like there might be a method for doing this, and something I'm missing that I'll regret down the road if I don't find it.

  • Retrieving part of a string using jQuery / JavaScript

    - by ILMV
    I know how I would achieve this using PHP, but with jQuery / JavaScript I'm not sure how to, here's the string I'm dealing with (It's the name attribute from a input element): Field[0][some_random_text] I want to retrieve the value some_random_text and slap it in a variable, I guess I would usually use regex to accomplish this task but not sure how this is done in JavaScript. Here are some characteristics of this name attribute. It will always be in this format string[string][string] Each of the strings can be any length How would I get the some_random_text string? I'd like to stick to the standard set of functions if possible.

  • Reading Stacktrace in Objective-C?

    - by yar
    I don't like real-time debugging much, but if it's necessary I'll do it. Is there any way to figure out what line of code a StackTrace in Objective-C refers to? What about the variable it refers to? For instance: 2010-05-13 19:39:11.673 Thingers[21003:207] *** -[NSCFString count]: unrecognized selector sent to instance 0x3b0ebb0 2010-05-13 19:39:11.674 Thingers[21003:207] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSCFString count]: unrecognized selector sent to instance 0x3b0ebb0' 2010-05-13 19:39:11.675 Thingers[21003:207] Stack: ( 29303899 ... 11130 ) I see that we're talking about sending a count message to something that doesn't have it (maybe it's a NSCFString?), but is there any way to figure out what a/the named reference to that instance (0x3b0ebb0) refers to?

  • will paginate, nested routes, ruby, rails

    - by Sam
    I'm trying to get will paginate to link to my nested route instead of the regular posts variable. I know I'm supposed to pass some params to paginate but I don't know how to pass them. Basically there is an array stored in @posts and the other param paginate has access to is category_id. The nested route is /category/1/posts but hitting next and previous on will paginate returns a url like this posts?page=1&category_id=7. <%= will_paginate @most_recent_posts "What do I do here?" %> This is the result of Yannis's answer: In your controller you can do: @posts = @category.posts.paginate And in your view: <%= will_paginate(@post) %> Doing this comes up with the following URL posts?page=2&post_category_id=athlete_management routes.rb #there are more routes but these are the relevant ones map.resources :posts map.resources :post_categories, :has_many => :posts solution map.resources :post_categories do |post_category| post_category.resources :posts end map.resources :posts Had to declare the resource after the block Thanks stephen!

  • How do I enumerate a list of interfaces that are directly defined on an inheriting class/interface?

    - by Jordan
    Given the following C# class: public class Foo : IEnumerable<int> { // implementation of Foo and all its inherited interfaces } I want a method like the following that doesn't fail on the assertions: public void SomeMethod() { // This doesn't work Type[] interfaces = typeof(Foo).GetInterfaces(); Debug.Assert(interfaces != null); Debug.Assert(interfaces.Length == 1); Debug.Assert(interfaces[0] == typeof(IEnumerable<int>)); } Can someone help by fixing this method so the assertions don't fail? Calling typeof(Foo).GetInterfaces() doesn't work because it returns the entire interface hierarchy (i.e. interfaces variable contains IEnumerable<int> and IEnumerable), not just the top level.

  • Problem passing ELMAH log id to Custom Error page in ASP.NET

    - by Ronnie Overby
    I am using ELMAH to log unhandled exceptions in an ASP.NET Webforms application. Logging is working fine. I want to pass the ELMAH error log id to a custom error page that will give the user the ability to email an administrator about the error. I have followed the advice from this answer. Here is my global.asax code: void ErrorLog_Logged(object sender, ErrorLoggedEventArgs args) { Session[StateKeys.ElmahLogId] = args.Entry.Id; // this doesn't work either: // HttpContext.Current.Items[StateKeys.ElmahLogId] = args.Entry.Id; } But, on the Custom error page, the session variable reference and HttpContext.Current.Items are giving me a NullReference exception. How can I pass the ID to my custom error page?

  • PHP Doctrine: Filter Table?

    I'm still not convinced after my previous question and some experience. Requirements: I don't want to use an SQL query everytime a filterBy() function is called and still be able to call -filterBy() on the returned table. Please find the comment @ ObjectsTable class: "How to instantiate another table and add records which match the filter criteria?" Usage: $globaltable = new ObjectsTable(); //globally accessible variable $globaltable->findAll(); //this call is made once at the beginning of the request $globaltable->filterBy('somefield', $someValue); //this function is used all over the place ObjectsTable class: class ObjectsTable extends Doctrine_Table { function filterBy($field, $value) { //How to instantiate another table and add records which match the criteria? } }

  • See return value in C#

    - by Snake
    Hi, Consider the following piece of code: As you can see we are on line 28. Is there any way to see the return value of the function at this point, without letting the code return to the caller function? Foo.Bar() is a function call which generates a unique path (for example). So it's NOT constant. In VB.NET it's possible by entering the function's name in the Watch, which will then threat it as a variable. But in C# this is not possible, any other tips? PS: rewriting is not an option.
