• Extending existing Class in Symfony

  - by Dar Hamid

  I am new to symfony. I have created a registration form using the code: $user = new Register(); $form = $this->createForm(new RegisterType(), $user); In the RegisterType class i have 5 fields (for example).I store the values in database when the user registers with the system. Now I display the EDIT page using following code: $user = $em->getRepository('MysiteUserBundle:Register')->find($id); $form = $this->createForm(new RegisterType(), $user); The problem with the EDIT code however is that it displays me all of the fields mentioned in RegisterType class.Is it possible to display only some fields. If yes how can this be achieved. Any help will be appreciated

• Convert string to variable in Javascript

  - by waiwai933

  Is there any way to convert a string to a variable in Javascript? Right now, what I have is a script that updates data based on the values of the select box: <script type="text/javascript"> var a = new Array(); a[0] = 'Name'; a[1] = 'Description'; var b = new Array(); b[0] = 'Name 2'; b[1] = 'Description 2'; function changeSystem(){ var selectedAccount=document.getElementById('selected_option').value; document.getElementById('name').innerHTML = selectedAccount[0]; document.getElementById('description').innerHTML = selectedAccount[1]; } </script> <form method="POST"> <select onchange="changeSystem()" id="selected_option"> <option>A</option> <option>B</option> </select> </form> <span id="name"></span><br> <span id="description"></span><br> selectedAccount is the string of the chosen element in <select>. However, for it to access the array, it needs to be a variable, i.e. a[0] instead of 'a'[0]. What solutions are there to this?

• How should I build a privacy drop-down (select) menu?

  - by animuson

  I'm trying to build something similar to Facebook's privacy selection menu, except without the 'custom' option. It will only list a few options such as 'show to all', 'show to friends only', or 'completely hidden'. Right now I'm thinking of using simple JavaScript to change a hidden input field to the new value they click on, so if they clicked on the division for 'show to friends only' it would change the corresponding field, say 'email_privacy', to 1. Is there a better way to do this or am I pretty much on track? P.S. I am not planning on using a select element, I was planning on building a custom drop-down menu using CSS since select elements are so highly non-customizable. I'm doing it this way to save space, rather than having this massive selection menu at the right which takes up a bunch of space. Note: I'm not really interested in using jQuery, that's just extra libraries and crap that I don't want to load. I can do it in JavaScript just as easily so I might as well use that.

• Place an object on top of stack in ILGenerator

  - by KiNGPiN

  I have to pass a function an instance of an object, so obviously all the information to be taken as argument is to be loaded onto the evaluation stack Here is the code that i am looking for someClass SomeObject = new someClass(); il.Emit(OpCodes.LoadObject, SomeObject); il.Emit(OpCodes.CallVirt, MethodInfo Function); public void Function(Object obj) { Type type = typeof(obj); //do something w.r.t to the type } I dont require any information stored in the class just the type and i cannot use any of the primitive types to take my decision on Last i read that i can use a pointer to load the type using some opcodes ... but i am completely lost here, any help or pointers to the right direction would be great :)

• Django: How to dynamically add tag field to third party apps without touching app's source code

  - by Chris Lawlor

  Scenario: large project with many third party apps. Want to add tagging to those apps without having to modify the apps' source. My first thought was to first specify a list of models in settings.py (like ['appname.modelname',], and call django-tagging's register function on each of them. The register function adds a TagField and a custom manager to the specified model. The problem with that approach is that the function needs to run BEFORE the DB schema is generated. I tried running the register function directly in settings.py, but I need django.db.models.get_model to get the actual model reference from only a string, and I can't seem to import that from settings.py - no matter what I try I get an ImportError. The tagging.register function imports OK however. So I changed tactics and wrote a custom management command in an otherwise empty app. The problem there is that the only signal which hooks into syncdb is post_syncdb which is useless to me since it fires after the DB schema has been generated. The only other approach I can think of at the moment is to generate and run a 'south' like database schema migration. This seems more like a hack than a solution. This seems like it should be a pretty common need, but I haven't been able to find a clean solution. So my question is: Is it possible to dynamically add fields to a model BEFORE the schema is generated, but more specifically, is it possible to add tagging to a third party model without editing it's source. To clarify, I know it is possible to create and store Tags without having a TagField on the model, but there is a major flaw in that approach in that it is difficult to simultaneously create and tag a new model.

• Updating form values with javascript

  - by shinjuo

  I have a page that I made that is going to be used for retrieving shipping rates from UPS by entering the weight and zip. Everything works fine but what I want to add to it is the ability for the user to choose something on a form and have it update the value in a different form box. I think this is done with javascript. Any suggestions will help.

• Codeigniter - form not rendering on live server?

  - by pingu

  hi guys, I've written a small website with CI, which is all working fine on dev. However, when I copy the files over for live, everything works except for my form which is not being rendered. I am using <?php echo form_open('home'); ?> and <?php echo form_close(); ?> The form fields within the form, which I'm generating as follows are being rendered fine, but there is simply no form around them?! <?php $data = array( 'name'=> 'name', 'id'=> 'name', 'class'=>'textfield', 'value' => set_value('name') ); echo form_input($data); ?> Any ideas - I've used CI on a few apps, and this is the first time I've come across this issue. I've got all the helpers etc called correctly, as this is working perfectly in the development environment.

• Jquery post array via ajax

  - by Dan

  I have an array (for checkboxes) that I need to pass alongside the regular form in an ajax post, but can't seem to get this to work: new_data = [a,b,c,d,e]; somedata_assoc = JQuery.param({'choices[]': new_data}); $.ajax({ type: "POST", url: contract_qurl, data: $(div).find("form").serialize()+"&"+somedata_assoc, context: $(this), success: function(data) { $("#results_table").html(data); } });

• Why is my asp.net mvc form POSTing instead of GETting?

  - by quakkels

  My code is straightforward enough: <% using(Html.BeginForm(FormMethod.Get)) %> <% { %> Search for in Screen Name and Email: <%: Html.TextBox("keyword", Request.QueryString["keyword"]) %> <button type=submit>Search</button> <% } %> The issue I'm running into is that when I submit this form, the values are not added to the querystring. Instead, it appears that the form is submitting by a post request. When I look at the generated HTML, I have this: <form action="/find/AdminMember/MemberList" method="post"> Search for in Screen Name and Email: <input id="keyword" name="keyword" type="text" value="" /> <button type=submit>Search</button> </form> Does anyone know why? This seems pretty simple and straighforward to me.

• Center aligned form with equal width labels

  - by James Goodwin

  I have a very simple web form which consists of labels and input fields, however I can not seem to find a way of aligning the form in the center of the page and for the labels to have an equal width so that they appear neatly next to each other, one under the other. The structure of my page is basically: <body> <div class="form"> <form method="post"> <fieldset> <label>Mobile:</label><input type="text" name="msisdn"><br/> <label>Code:</label><input type="text" name="code"><br/> <br/> <input type="image" src="submit-button.gif" alt="Submit"> <br/> <input type="checkbox" name="ts_and_cs"><label> Accept Terms and Conditions</label> <br/><br/> </fieldset> </form> </div> </body> Usually I would fix this by doing float:left on the label fields and setting a width on the labels, however for this I need the labels and input fields to be centered on the page. Also I am not able to set the width of the page (or any containing divs) as the page will be displayed on mobile devices with different screen sizes. Any suggestions as to how best style the form? Thanks

• What is the best way to get support from microsoft developers [closed]

  - by Malcolm Frexner

  I have a problem at my production web, that I am not able to solve. I am not able to reproduce the problem in stage or development. It only appears when the website is under heavy load. I think it is solvable if somebody who has a very good understanding of the internals of FormsAuthentication would have a look at it by logging into our system. It should be at least Scottgu! Somebody told me that Microsoft Premier Support is a good choice for this kind of problems. We have no MSDN subscription or other connection to microsoft that enables us to use MPS. Is there a way to get support on a incident base? Are there other ways to get this kind of support? EDIT Here is the problem itself: http://stackoverflow.com/questions/2448720/different-users-get-the-same-cookie-value-in-aspxanonymous

• Making form submissions unique using PHP and HTML

  - by canadiancreed

  Hello all I'm currently developing a page where the user fills out a form, and when submitted they are taken to the next page. When on the next page, I want to have it so that if the user went back to the previous page using the back button, or hit refresh, the submission will not be saved into the DB. Now I recall reading somewhere that if you had a way to make each submission unique, this issue is averted, but after screwing around for hours on end, for the life of me I cannot recall how this could be done (using PHP), so long story short has anyone ran into this, and if so, what was your solution?

• Programmatically loading Entity classes with JPA 2.0?

  - by Dennetik

  With Hibernate you can load your Entity classes as: sessionFactory = new AnnotationConfiguration() .addPackage("test.animals") .addAnnotatedClass(Flight.class) .addAnnotatedClass(Sky.class) .addAnnotatedClass(Person.class) .addAnnotatedClass(Dog.class); Is there a way to do the same thing - programmatically loading your Entity classes - in a JPA 2.0 compliant way?

• How to make the value of one select box drive the options of a second select box

  - by Ben McCormack

  I want to make an HTML form with 2 select boxes. The selected option in the first select box should drive the options in the second select box. I would like to solve this dynamically on the client (using javascript or jQuery) rather than having to submit data to the server. For example, let's say I have the following Menu Categories and Menu Items: Sandwiches Turkey Ham Bacon Sides Mac 'n Cheese Mashed Potatoes Drinks Coca Cola Sprite Sweetwater 420 I would have two select boxes, named Menu Category and Items, respectively. When the user selects Sandwiches in the Menu Category box, the options in the Items box will only show Sandwich options. I'm stuck as how I might approach this. Once I filter out the 2nd list one time, how do I "find" the list options once I change my menu category in the 1st list? Also, if I'm thinking in SQL, I would have a key in the 1st box that would be used to link to the data in the 2nd box. However, I can't see where I have room for a "key" element in the 2nd box. How could this problem be solved with a combination of jQuery or plain javascript?

• Adding classes to all form widgets in symfony

  - by rlahay

  Hi everyone, I am trying to find a better way to assign classes to form elements in symfony. Currently, I can't seem to get away from assigning each one manually. ie: $this->widgetSchema['title']->setAttribute("class","fieldInput"); $this->widgetSchema['tag_line']->setAttribute("class","fieldInput"); $this->widgetSchema['description']->setAttribute("class","fieldInput"); // etc Things I tried without success 1) looping through $this-widgetSchema, treating it as an array and setting attributes to each key 2) $this-widgetSchema-setAttribute() but this only applied the class to the label that was generated, not the form element There must be a way to hit all the fields without specifically directing them? Can anyone point me in the right direction?

• How to block non-browser clients from submitting a request?

  - by Thomas Kohl

  I want to block non-browser clients from accessing certain pages / successfully making a request. The website content is served to authenticated users. What happens is that our user gives his credentials to our website to 3rd party - it can be another website or a mobile application - that performs requests on his behalf. Say there is a form that the user fills out and sends a message. Can I protect this form so that the server processing the submission can tell whether the user has submitted it directly from the browser or not? I don't want to use CAPTCHA for usability reasons. Can I do it with some javascript?

• Assigned numbers to movie clip to plug in formula... not working

  - by Matthew MlgPro Harding

  So I am attempting to vertically evenly space these movie clips so I came up with a math formula involving n( the button number) but Its not working. var buttonArray:Array = [ side_banner.btn1, side_banner.btn2, side_banner.btn3, side_banner.btn4]; var buttonCount:uint = buttonArray.length; for (var i:uint=0; i< buttonCount; i++) { buttonArray[i].addEventListener(MouseEvent.CLICK, outputNumber); buttonArray[i].theTrigger = [i + 1]; } function outputNumber(e:MouseEvent):void { trace( e.target.theTrigger); buttonArray[i].y = (((stage.stageHeight - 400)/4)*(e.target.theTrigger)) - ((stage.stageHeight - 400)/4)/2 } But apparently each movie clip doesn't actually have a numerical value just a numeric name... how can I get the "n" btn number to use my formula? Thanks

• IIS Restrict Access to Directory for table of users

  - by Dave

  I am trying to restrict access to files in a directory and it's sub directories based user rights. My user rights are stored in an MS SQL database in a custom format, however it is easy to query the list of users with rights to this directory. I need to know how to apply this to a web config on the server to authenticate against a query of a database table to determine if the username is authenticated and allowed to view the file. Of course if they are not they should be blocked / given a 404. I am using IIS and ASP.Net MVC3 with a form based security as opposed to the built in roles and responsibilities that was custom made for us and that works great. There are over 10k users tied to this non-Active Directory authentication so I am not planning to change my authentication type so please don't go there. It is not my decision on the choice of platform, or I would have gone with a LAMP server and been done with this. Edit 11-13-2012 @ 8:57a: In the web config can you put the result of an SQL query?

• How to add default value on save form?

  - by Ignacio

  I have an object Task and a form that saves it. I want to automatically asign created_by field to the currently logged in user. So, my view is this: def new_task(request, task_id=None): message = None if task_id is not None: task = Task.objects.get(pk=task_id) message = 'TaskOK' submit = 'Update' else: task = Task(created_by = GPUser(user=request.user)) submit = 'Create' if request.method == 'POST': # If the form has been submitted... form = TaskForm(request.POST, instance=task) if form.is_valid(): task = form.save(commit=False); task.created_by = GPUser(user=request.user) task.save() if message == None: message = 'taskOK' return tasks(request, message) else: form = TaskForm(instance=task) return custom_render('user/new_task.html', {'form': form, 'submit': submit, 'task_id':task.id}, request) The problem is, you guessed, the created_by field doesn't get saved. Any ideas? Thanks

• How do I sanitize a string in PHP that contains "; Echo"? (I have a solid reason)

  - by user337878

  I turned this case into a simple PHP page that submits to itself. My issue is that I am submitting track meet results and one of the girl's names is Echo...a lovely name. The problem text I'm submitting is: Pole vault - Rachel Simons, Tow, 8-6; Echo Wilson, Cit, 8-0; Molly Randall, Tow, 7-0; So you see a semicolon followed by white space followed by Echo... After submitting, it says: POST to /results/test.php not supported The end goal is to save it to a database along with some other info and have a search page to find it and simply print out the full result on the screen. I stripped out all my database stuff to get it down to this one error. I mean, I can intentionally mis-spell her name, but there's gotta be a way around this, right??? Here's the test PHP file. <html> <head> <title>title</title> </head> <body> <?php echo "<h3>Edit meet info below</h3>"; echo "<form action=\"test.php\" method=\"post\" id=\"submitForm\">"; echo "Full Results:<br/><textarea NAME=\"results\" id=\"results\" rows=\"20\" cols=\"80\" MAXLENGTH=\"8191\"></textarea><br/><br/>"; echo "<input type=\"submit\" name=\"submitMeet\" value=\"Submit\">"; echo "</form>"; ?> </body> </html>

• Symfony2 Entity to array

  - by Adriano Pedro

  I'm trying to migrate my flat php project to Symfony2, but its coming to be very hard. For instance, I have a table of Products specification that have several specifications and are distinguishables by its "cat" attribute in that Extraspecs DB table. Therefore I've created a Entity for that table and want to make an array of just the specifications with "cat" = 0... I supose the code is this one.. right? $typeavailable = $this->getDoctrine() ->getRepository('LabsCatalogBundle:ProductExtraspecsSpecs') ->findBy(array('cat' => '0')); Now how can i put this in an array to work with a form like this?: form = $this ->createFormBuilder($product) ->add('specs', 'choice', array('choices' => $typeavailableArray), 'multiple' => true) Thank you in advance :) # Thank you all.. But now I've came across with another problem.. In fact i'm building a form from an existing object: $form = $this ->createFormBuilder($product) ->add('name', 'text') ->add('genspec', 'choice', array('choices' => array('0' => 'None', '1' => 'General', '2' => 'Specific'))) ->add('isReg', 'choice', array('choices' => array('0' => 'Material', '1' => 'Reagent', '2' => 'Antibody', '3' => 'Growth Factors', '4' => 'Rodents', '5' => 'Lagomorphs'))) So.. in that case my current value is named "extraspecs", so i've added this like: ->add('extraspecs', 'entity', array( 'label' => 'desc', 'empty_value' => ' --- ', 'class' => 'LabsCatalogBundle:ProductExtraspecsSpecs', 'property' => 'specsid', 'query_builder' => function(EntityRepository $er) { return $er ->createQueryBuilder('e'); But "extraspecs" come from a relationship of oneToMany where every product has several extraspecs... Here is the ORM: Labs\CatalogBundle\Entity\Product: type: entity table: orders__regmat id: id: type: integer generator: { strategy: AUTO } fields: name: type: string length: 100 catnumber: type: string scale: 100 brand: type: integer scale: 10 company: type: integer scale: 10 size: type: decimal scale: 10 units: type: integer scale: 10 price: type: decimal scale: 10 reqcert: type: integer scale: 1 isReg: type: integer scale: 1 genspec: type: integer scale: 1 oneToMany: extraspecs: targetEntity: ProductExtraspecs mappedBy: product Labs\CatalogBundle\Entity\ProductExtraspecs: type: entity table: orders__regmat__extraspecs fields: extraspecid: id: true type: integer unsigned: false nullable: false generator: strategy: IDENTITY regmatid: type: integer scale: 11 spec: type: integer scale: 11 attrib: type: string length: 20 value: type: string length: 200 lifecycleCallbacks: { } manyToOne: product: targetEntity: Product inversedBy: extraspecs joinColumn: name: regmatid referencedColumnName: id HOw should I do this? Thank you!!!
