  • Sending login form to an open-mesh acess point for authentication with my own RADIUS server

    - by PachinSV
    I have my RADIUS server up and running and a custom external captive portal. But I'm not sure: what information should I send to the Open-Mesh AP with my login form (it is necessary to encrypt the password?, because if I don't use a secret word to encrypt in my network configuration the RADIUS server complaints about it and in the log shows me some strange characters in the password) I don't know what to do with the "challenge" and "md" parameters in my login splash page. Thank you very much for your help.

  • XNA - Detect click on triangle/circle form of a texture

    - by chr1s89
    How can i detect clicks on a texture (will be a button in my game) that has a form of a triangle or circle. I know only the rectangle solution where u can use the positions + the width/height but this dont work for that because clicks will be detected at the transparent pixels. I heard of pixel-perfect collision is it the right way for this? It would be great if someone can give me a example for such a solution or other.

  • How can I highlight empty fields in ASP.NET MVC 2 before model binding has occurred?

    - by Richard Poole
    I'm trying to highlight certain form fields (let's call them important fields) when they're empty. In essence, they should behave a bit like required fields, but they should be highlighted if they are empty when the user first GETs the form, before POST & model validation has occurred. The user can also ignore the warnings and submit the form when these fields are empty (i.e. empty important fields won't cause ModelState.IsValid to be false). Ideally it needs to work server-side (empty important fields are highlighted with warning message on GET) and client-side (highlighted if empty when losing focus). I've thought of a few ways of doing this, but I'm hoping some bright spark can come up with a nice elegant solution... Just use a CSS class to flag important fields Update every view/template to render important fields with an important CSS class. Write some jQuery to highlight empty important fields when the DOM is ready and hook their blur events so highlights & warning messages can be shown/hidden as appropriate. Pros: Quick and easy. Cons: Unnecessary duplication of importance flags and warning messages across views & templates. Clients with JavaScript disabled will never see highlights/warnings. Custom data annotation and client-side validator Create classes similar to RequiredAttribute, RequiredAttributeAdapter and ModelClientValidationRequiredRule, and register the adapter with DataAnnotationsModelValidatorProvider.RegisterAdapter. Create a client-side validator like this that responds to the blur event. Pros: Data annotation follows DRY principle (Html.ValidationMessageFor<T> picks up field importance and warning message from attribute, no duplication). Cons: Must call TryValidateModel from GET actions to ensure empty fields are decorated. Not technically validation (client- & server-side rules don't match) so it's at the mercy of framework changes. Clients with JavaScript disabled will never see highlights/warnings. Clone the entire validation framework It strikes me that I'm trying to achieve exactly the same thing as validation but with warnings rather than errors. It needs to run before model binding (and therefore validation) has occurred. Perhaps it's worth designing a similar framework with annotations like Required, RegularExpression, StringLength, etc. that somehow cause Html.TextBoxFor<T> etc. to render the warning CSS class and Html.ValidationMessageFor<T> to emit the warning message and JSON needed to enable client-side blur checks. Pros: Sounds like something MVC 2 could do with out of the box. Cons: Way too much effort for my current requirement! I'm swaying towards option 1. Can anyone think of a better solution?

What should I do? when I try to use br.select_form(name = "") i get errors that no form is declared with that name, and the function requires a name input. There is only one form on the page, is there some other way I can select that form?

  • Looping through array in PHP to post several multipart form-data

    - by Léon Pelletier
    I'm trying in an asp web application to code a function that would loop through a list of files in a multiple upload form and send them one by one. Is this something that can be done in ASP? Because I've read some posts about how to attach several files together, but saw nothing about looping through the files. I can easily imagine it in C# via HttpWebRequest or with socket, but in php, I guess there are already function designed to handle it? // This is false/pseudo-code :) for (int index = 0; index < number_of_files; index++) { postfile(file[index]); } And in each iteration, it should send a multipart form-data POST. postfile(TheFileInfos) should make a POST like it: POST /afs.aspx?fn=upload HTTP/1.1 [Header stuff] Content-Type: multipart/form-data; boundary=----------Ef1Ef1cH2Ij5GI3ae0gL6KM7GI3GI3 [Header stuff] ------------Ef1Ef1cH2Ij5GI3ae0gL6KM7GI3GI3 Content-Disposition: form-data; name="Filename" myimage1.png ------------Ef1Ef1cH2Ij5GI3ae0gL6KM7GI3GI3 Content-Disposition: form-data; name="fileid" 58e21ede4ead43a5201206101806420000007667212251 ------------Ef1Ef1cH2Ij5GI3ae0gL6KM7GI3GI3 Content-Disposition: form-data; name="Filedata"; filename="myimage1.png" Content-Type: application/octet-stream [Octet Stream] [Edit] I'll try it: <html> <head> <title>Untitled Document</title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> </head> <body> <form name="form1" enctype="multipart/form-data" method="post" action="processFiles.php"> <p> <? // start of dynamic form $uploadNeed = $_POST['uploadNeed']; for($x=0;$x<$uploadNeed;$x++){ ?> <input name="uploadFile<? echo $x;?>" type="file" id="uploadFile<? echo $x;?>"> </p> <? // end of for loop } ?> <p><input name="uploadNeed" type="hidden" value="<? echo $uploadNeed;?>"> <input type="submit" name="Submit" value="Submit"> </p> </form> </body> </html>

  • How to structure a Kohana MVC application with dynamically added fields and provide validation and f

    - by Matt H
    I've got a bit of a problem. I have a Kohana application that has dynamically added fields. The fields that are added are called DISA numbers. In the model I look these up and the result is returned as an array. I encode the array into a JSON string and use JQuery to populate them The View knows the length of the array and so creates as many DISA elements as required before display. See the code below for a summary of how that works. What I'm finding is that this is starting to get difficult to manage. The code is becoming messy. Error handling of this type of dynamic content is ending up being spread all over the place. Not only that, it doesn't work how I want. What you see here is just a small snippet of code. For error handling I am using the validation library. I started by using add_rules on all the fields that come back in the post. As they are always phone numbers I set a required rule (when it's there) and a digit rule on the validation-as_array() keys. That works. The difficulty is actually giving it back to the view. i.e. dynamically added javascript field. Submits back to form. Save contents into a session. View has to load up fields from database + those from the previous post and signal the fields that have problems. It's all quite messy and I'm getting this code spread through both the view the controller and the model. So my question is. Have you done this before in Kohana and how have you handled it? There must be an easier way right? Code snippet. -- edit.php -- public function phone($id){ ... $this->template->content->disa_numbers = $phones->fetch_disa_numbers($this->account, $id); ... } -- phones.php -- public function fetch_disa_numbers($account, $id) { $query = $this->db->query("SELECT id, cid_in FROM disa WHERE owner_ext=?", array($id)); if (!$query){ return ''; } return $query; } -- edit_phones.php --- <script type="text/javascript"> var disaId = 1; function delDisaNumber(element){ /* Put 'X_' on the front of the element name to mark this for deletion */ $(element).prev().attr('name', 'X_'+$(element).prev().attr('name')); $(element).parent().hide(); } function addDisaNumber(){ /* input name is prepended with 'N_' which means new */ $("#disa_numbers").append("<li><input name='N_disa"+disaId+"' id='disa'"+ "type='text'/><a class='hide' onClick='delDisaNumber(this)'></a></li>"); disaId++; } </script> ... <php echo form::open("edit/saveDisaNumbers/".$phone, array("class"=>"section", "id"=>"disa_form")); echo form::open_fieldset(array("class"=>"balanced-grid")); ?> <ul class="fields" id="disa_numbers"> <?php $disaId = 1; foreach ( $disa_numbers as $disa_number ){ echo '<li>'; echo form::input('disa'.$disaId, $disa_number->cid_in); echo'<a class="hide" onclick="delDisaNumber(this)"></a>'; echo "</li>"; $disaId++; } ?> </ul> <button type="button"onclick="addDisaNumber()"><a class="add"></a>Add number</button> <?php echo form::submit('submit', 'Save'); echo form::close(); ?>

  • jQuery validation: how to customize trigger and response

    - by user302307
    I am new with jQuery. I have a servlet based application which render an HTML form. This form is submitted via a function and the submit button IS NOT submit button in HTML. It's a regular button that calls a javascript function to do the submission. When running the submission function, the servlet also run a function called doCheck() which is in javascript. This doCheck() function can be defined per page basis. if doCheck returns false, then the servlet will stop the submission; else it will submit the form. I want to use jQuery validation to fit the servlet application. Is there a way to customize jQuery validation to be triggered manually (ie. only when doCheck() is executed) but at the same time provides continuous check on the UI (ie. if one type invalid number in date field, it will gives the appropriate msg when onblur event happen)? Is there a way to make jQuery validation return true or false? Thank you.

  • 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.

  • Custom Validation Attribute with Custom Model Binder in MVC 2

    - by griegs
    I apologise for the amount of code I have included. I've tried to keep it to a minimum. I'm trying to have a Custom Validator Attribute on my model as well as a Custom Model binder. The Attribute and the Binder work great seperately but if I have both, then the Validation Attribute no longer works. Here is my code snipped for readability. If I leave out the code in global.asax the custom validation fires but not if I have the custom binder enabled. Validation Attribute; public class IsPhoneNumberAttribute : ValidationAttribute { public override bool IsValid(object value) { //do some checking on 'value' here return true; } } Useage of the attribute in my model; [Required(ErrorMessage = "Please provide a contact number")] [IsPhoneNumberAttribute(ErrorMessage = "Not a valid phone number")] public string Phone { get; set; } Custom Model Binder; public class CustomContactUsBinder : DefaultModelBinder { protected override void OnModelUpdated(ControllerContext controllerContext, ModelBindingContext bindingContext) { ContactFormViewModel contactFormViewModel = bindingContext.Model as ContactFormViewModel; if (!String.IsNullOrEmpty(contactFormViewModel.Phone)) if (contactFormViewModel.Phone.Length > 10) bindingContext.ModelState.AddModelError("Phone", "Phone is too long."); } } Global asax; System.Web.Mvc.ModelBinders.Binders[typeof(ContactFormViewModel)] = new CustomContactUsBinder();
