  • codeigniter and form action trailing / issue??

    - by alex
    Hi, I am having a bit of an issue with the way CI is dealing with /. In a regular form i notice that the following form action didn't work action="mydomain.com/ci-controller/login/" but this one does work action="mydomain.com/ci-controller/login" Strange but he it worked. But now i need this from a iframe, i the iframe i have a login form which sets the parents url to mydomain.com/ci-controller/login, but i get the same error as it was calling mydomain.com/ci-controller/login/ Could my problem be that the call from the iframe adds a trailing / which is not visible?? Any thoughts

  • extending spring form tag library attributes

    - by TimmyJ
    I'm using Spring's form tag library in a Spring MVC application that I am developing. The company I am working for has implemented some company-wide policies based on the definition of custom attributes for certain tags. For instance, by default (though the inclusion of a standard javascript file) all tags have their values automatically converted to upper case. In order to disable this one would define their tag with a custom attribute in the following way: <input type="text" uppercase="false" /> The problem is that the addition of these custom attributes to a spring:form tag causes an error at runtime. I've pasted the error below. org.apache.jasper.JasperException: /WEB-INF/jsp/reportCriteria.jsp(45,5) Attribute uppercase invalid for tag input according to TLD My question is: is there any way to extend the TLD to allow for these attributes, or is there any other way add these custom attributes to these spring:form tags?

  • Question about a dialog form and submit errors

    - by user248959
    Hi, I have the link below that executes the action message/new which shows a form inside a jqueryui modal dialog. <div id="myDialog"> </div> echo jq_link_to_remote('Enviar mensaje', array( 'url' => 'mensaje/new?receptor='.$miembro->getId().'&tipo=0&estado=0', 'update' => 'myDialog', 'complete' => "jQuery('#myDialog').dialog({ width:375, height:220, top:123, resizable:false, modal:true, autoOpen: false }); jQuery('#myDialog').dialog('open')" )); The point: if there are submit errors the form is not showed inside the dialog form but in a empty page (mensaje/create).. Any idea? Javi

  • CakePHP Form Helper - Show error class, but not error message

    - by Jeremy Penrod
    I'm attempting to customize the error output on the CakePHP 2.0 form helper. Currently, the form renders error messages below the input and applies an 'error' class to the input's label. I have found that I can either disable error reporting altogether for an input, or output the error class and message. I would like the error class to be applied to the label of the offending inputs WITHOUT any message below. How do you turn off the error message outputting for a form, BUT still apply error classes to offending labels?

  • How can I inherit form and access controls from mother form?

    - by kasia
    Hi, I'm in the middle of writing my project and I have this problem: I try to write a library and I want to use it in my application. In library I have a form with menu strip, tool bar, list view, tree view and etc. Everything in library is protected. In my application I have created the form which inherit form the library. I can change and add new functionality to list view and tree view using designer panel in VS 2008 but I don't have access to menu strip and tool bar, even though they are protected. Why is that so? I will be thankful for some advice.

  • MVC for web development: Sign-up form?

    - by incrediman
    How would I go about implementing a signup form using the MVC pattern for a website (I'm using PHP)? I think the controller should receive the POST data initially. Then probably some interation with the model might need to take place (if the user successfully signs up). Then I think the signup form view would be called, and a value would be passed in saying whether or not the signup was successful. Stuff I need help with: Where do I do input validation (ie. proper email address formatting)? How do I check to make sure the username is unique? Is the rest of my description alright? How would you go about doing an MVC website signup form?

  • How to add ucwords and strtolower to this form

    - by Liso22
    I want "s.value" to be turned all to lowercase and then ucwords to it but I don't know how to do it since it's inside a form. Basically I want to do something like this: ucwords(strtolower( s.value here )); This is the form: <form role="search" method="get" id="searchform" action="http://chusmix.com/?s=" onsubmit="if (document.getElementById('s2').value.length > 5) window.location = action + '<php echo $city; ?>++++' + s.value; return false;" > Thanks

  • Filling in a form client-side [Javascript]

    - by Hawker
    I'm coding up a small Vista/7 sidebar gadget for our web based employee schedule system and I've run into a Javascript problem that my Google-FU can't solve. I can't figure out how to fill in a login form from the client. I'm creating a new ActiveXObject, navigating to the site, but lost as to where to go from here. var conn = new ActiveXObject("Microsoft.XMLHTTP"); conn.open("POST", "url", false); conn.send(null); Can access the form from the ActiveXObject based on the form id? I'd also assume I'm going to need to change a few headers for a POST vs. a GET? Thanks for any tips or links to references! I can't seem to find much and JavaScript isn't my forte.

  • Embed form in another website - pitfalls

    - by Paddy
    Scenario: We provide a hosted site that clients pay to use internally (a tool to support their business workflow). We have a requirement to provide a form that the clients can 'embed' in their outward facing site. This form will permit a member of the public to enter some details to register an interest - this data will be pushed to our remote system. Question: I'm currently planning on creating a simple HTML page that the client's web guys can include in a simple fashion on their site (either using an iframe or an object tag). If I do this, am I going to run into difficulties when the user tries to submit the embedded form (as it will be going to different domain to the one they are currently browsing)? I had a look at google adsense and I see that they just provide a link to a JS file that renders their ads - I'm not sure I see the advantage in this, but if anybody has any bright ideas... Whatever technique that gets used, I'll have to authenticate the request as coming from my client's site(s).

  • php mail send form question?

    - by eberswine
    Wondering if anyone know how to automatically send the user an email after he/she fills out a form. I have the form emailed to me after it gets submitted, but I can't figure out how to capture the user's email from the form field and have it send it to them automatically??? Here is some code that I use to send the mail: //mail the message before redirecting if($_POST['dosend'] == "yes"){ // The message $headers = "From: [email protected]"; $message = "NEW Message :: ".$_POST['event_name']." \n Email: ".$_POST['email']." \n Click link to http://www.domain.com/admin/ Approve this Event!"; // Send mail('[email protected]', 'New :: Calendar Message', $message, $headers); } //end mail

  • Best way to find all input elements inside a form using jQuery

    - by Aayush
    I need to find all form elements inside inside a form and trigger a flag on change in the value. Currently I am using the method below. I am not sure if this works or not. But It surely works for: .find('input[type=text]) $('#form').find('input[type=text], input[type=radio], input[type=checkbox], select, textarea').each(function(){ $(this).change(function(){ if( change !== 1 ) change = 1; }); }) Now I have added multiple elements with the comma. Will this work and is this the best way to do this. Appreciate all the help. Thanks!

  • vb express / visual studio - is it possible to run / debug one form only in a multi form application

    - by Luay
    hi, I have a vb application consisting of several winForms and code files. Is it possible to run / debug only one form without having to run the whole application? To be more specific, one of the forms in my application is the settings form where the user sets his/her desired options. These options are read/written to an xml file. Is it possible to debug just this one form (and not the whole program) to see if the reading/writing went well, if everything displayed correctly... ? If I am thinking the wrong way about this, could you point me in the right direction? By the way, I am using visual basic express / visual studio.

  • ASP MVC Creating Form Rows Dynamically

    - by Jonathan Stowell
    Hi Guys, I haven't even attempted this yet and am creating this question for advice really. I have a strongly typed page which receives a form model composed of several components. It is to create a mitigating circumstance (MC) for a student at a university for my final year project. A MC can be composed of the initial problem, assessment extensions, and I use a multi select box to allow the user to select staff retrieved from the database which are able to view the MC once created. The thing is I feel that a student could be granted many assignment extensions for one problem. I am wander if it is possible to include a button/image on the form which when clicked will create a new assessment extension object, and duplicate the form components to set the values for the object? This would all need to occur without any page refreshes. Any advice, or links to good tutorials would be appreciated. I have so far been unable to find any suitable examples. Thanks, Jon

  • Using non-Railsy route to prepopulate a form

    - by user94154
    I have many instances of a Rails model, Post. When viewing an individual post, I'd like to create a form to create a child of Post called Comment. I'd like to prepopulate this form with a hidden tag that contains the post_id which is the foreign key in Comment. The Railsy way to do this is to create a fancy-ish route such as: /comments/new/post/:post_id However, this gunks up the routes file and doesn't leave much flexibility. Let's say I want to create a link somewhere else that prepopulates a different attribute of the form...then I'd have to add another route for this. So I think I'm going to create urls like this on /posts/show/:id: /comments/new?comment[post_id]=<%= @post.id %> This way I can add any other attributes as I need. I know the plus side associated with this, now what are the downsides?

  • Changing the way widgets are rendered/displayed in a form on the template

    - by user334017
    I have a form with a few other embedded forms and some various widgets. The widgets are all saved in an array $form['elements'] and for some of them, I want to display labels and things, but for others I only want to display the basic rendering. foreach($form['elements'] as $elem) echo $elem->render(); this displays everything about the widget. The way it is right now, I couldn't for example call $elem['..'] because the different subforms appear in a random order and have different variable names. I assume I could still put some checks in the template, but it seems easier to fix this in the widget class, like override one of the render functions or something. How would I go about doing this or do you have any links that could help me understand how do do this? on a side note, one of my widgets is the sfWidgetFormChoice and I have no clue where it actually renders or how renderer_classes work

  • Analog of Java Form Layout in Qt

    - by Narek
    Once I have programmed GUI with Java and have used Form Layouts. Form layout (if I am not mistaken that is from SWT library) made possible to give right, left, top and bottom adges of any GUI element (widget) with respect to other widgets in the same widget (parent widget) or with respect to the adges of parent widget. So it was possible to control the future of widgets that are inside of another one, when that "another widget" is being resized. In Qt I have find the QFormLayout which is similar to Java one, but seems I can't handle with widgets as flexible in terms of relative positioning, as it was with Java's Form Layout. So are there any other means to give a widget position with respect to the others (without overloading resizeEvent function) as that was in Java? Thanks.

  • Get items selected from another form

    - by Samarth Agarwal
    Hi I have a Windows Form application. I have a Textbox. I want to implement a functionality like when the user clicks on the textbox, a list should be made available to the user and then the item selected from the list should be filled in the textbox. The list should not be available if some other control is focussed other than the textbox. What would be the better way to do this? Should I implement the list in the same form as the textbox or should I use another form for the list? I want to implement a functionality like in the Tally Accounting Software.

  • Cannot submit form when disabling JSF page

    - by Steve
    Simple submit button. <h:commandButton actionListener="#{regBean.findReg}" action="#{regBean.navigate}" value="Search" /> The form tag is displayed like so: <h:form onsubmit="this.disabled=true;busyProcess();return true;"> This is so if the submit button is pressed, the page shows a "busy" icon until request is processed. The problem is, the request is never submitted and it never reaches the backend. However, if I instead take out the "disabled" call like so: <h:form onsubmit="busyProcess();return true;"> Everything works. Any ideas?

  • Suggestions on how to map from Domain (ORM) objects to Data Transfer Objects (DTO)

    - by FryHard
    The current system that I am working on makes use of Castle Activerecord to provide ORM (Object Relational Mapping) between the Domain objects and the database. This is all well and good and at most times actually works well! The problem comes about with Castle Activerecords support for asynchronous execution, well, more specifically the SessionScope that manages the session that objects belong to. Long story short, bad stuff happens! We are therefore looking for a way to easily convert (think automagically) from the Domain objects (who know that a DB exists and care) to the DTO object (who know nothing about the DB and care not for sessions, mapping attributes or all thing ORM). Does anyone have suggestions on doing this. For the start I am looking for a basic One to One mapping of object. Domain object Person will be mapped to say PersonDTO. I do not want to do this manually since it is a waste. Obviously reflection comes to mind, but I am hoping with some of the better IT knowledge floating around this site that "cooler" will be suggested. Oh, I am working in C#, the ORM objects as said before a mapped with Castle ActiveRecord. Example code: By @ajmastrean's request I have linked to an example that I have (badly) mocked together. The example has a capture form, capture form controller, domain objects, activerecord repository and an async helper. It is slightly big (3MB) because I included the ActiveRecored dll's needed to get it running. You will need to create a database called ActiveRecordAsync on your local machine or just change the .config file. Basic details of example: The Capture Form The capture form has a reference to the contoller private CompanyCaptureController MyController { get; set; } On initialise of the form it calls MyController.Load() private void InitForm () { MyController = new CompanyCaptureController(this); MyController.Load(); } This will return back to a method called LoadComplete() public void LoadCompleted (Company loadCompany) { _context.Post(delegate { CurrentItem = loadCompany; bindingSource.DataSource = CurrentItem; bindingSource.ResetCurrentItem(); //TOTO: This line will thow the exception since the session scope used to fetch loadCompany is now gone. grdEmployees.DataSource = loadCompany.Employees; }, null); } } this is where the "bad stuff" occurs, since we are using the child list of Company that is set as Lazy load. The Controller The controller has a Load method that was called from the form, it then calls the Asyc helper to asynchronously call the LoadCompany method and then return to the Capture form's LoadComplete method. public void Load () { new AsyncListLoad<Company>().BeginLoad(LoadCompany, Form.LoadCompleted); } The LoadCompany() method simply makes use of the Repository to find a know company. public Company LoadCompany() { return ActiveRecordRepository<Company>.Find(Setup.company.Identifier); } The rest of the example is rather generic, it has two domain classes which inherit from a base class, a setup file to instert some data and the repository to provide the ActiveRecordMediator abilities.

  • Create / build / generate a web form that can be on my server and has modern looks and could be impl

    - by Luay
    I have a small web site and would like to add a 'contact us' form and a 'feedback' form. i would like the forms to satisfy the following: 1- be modern looking (with beautiful css effects) 2- the form fields are validated properly and 'inline'. What I mean is once a user skips a required field or enters an email address incorrectly some kind of tooltip or icon is displayed to ask him to cerrect the error (as opposed to a message box that appears after the user clicks 'submit') 3- once the submit button is clicked the form contents are emailed to me. 4- the whole thing can be setup by a noob like myself. 5- no ads on the form I have been searching for at least 5 days for a solution but I can't seem to find anything the would satisfy the above 5 conditions. I don't mind paying for a solution as long as it is hosted on my site and it is a one off payment and not a monthly payment. So far my search has lead me to the following: 1 wufoo. The good: the generated forms seem to look okay but not the best there is. The bad: the free service is limited to 100 submissions. ads on the form. it is not hosted on my server. Paid service requires monthly payments 2- emailmeform: almost same as above except the generated form looks old. They do have an offer where you pay only $4 to get the form and set it up on your own site but that doesn't solve the fact that the forms look old. 3- formAssembly: same as above with minor variations (the generated form looks better) 4- formchamp, formthis, kontaktr,... And other similar online services: the same problem. either the form generated looks outdated or require monthly payments or they put ads...they don't satisfy my conditions. 5- coffeecup form builder. a desktop software. The problem is the generated forms look too old and use flash. 6- simfatic. Another software. Much better than coffeecup. almost satisfies my conditions but the forms not as good as I like. 7- many, many php scripts or html templates that look so outdated or fail when tested (probably because they are too old). Seriously guys, how hard is this. At least 90%+ of website contain at least a 'contact us' form. Why aren't there better solutions? if there is I can't seem to find them. In terms of looks I want something similar to this: http://web-kreation.com/articles/lightform-free-ajaxphp-contact-form/ It is called lightform. And this is a perfect example of what I mean by 'inline' validation. the only problem: there is no script to handle sending the mail. Even if I find one, I don't know how to modify it for my needs. So could you please help me out. I really can't search anymore. I reached rock bottom with this issue. I need a complete solution. If nothing exists then at least a: 1- form template (html) that looks nice and can easily be modified 2- a validation script that does 'inline' validation like the example above (or similar to it) and can be easily implemented by a noob like me to work with the html form. 3- a php script that will handle sending the email and can be easily implemented (all three working in harmony). I hope there is a complete solution but am I asking for too much? Pretty please...help...
