  • Validating single form field with CodeIgniter

    - by iamdadude
    Is there a quick way to validate a single form field with CodeIgniter to see whether or not that field matches a set of rules? There's the $this-form_validation-run();, but that will return either TRUE or FALSE for the whole form, and that's just not what I'm looking for. For example, if I only wanted to check if the email was valid, checking the whole form is not going to get me the result I'm looking for. I looked through the documentation but couldn't find anything like $this-form_validation-run(); that accepts one parameter and returns TRUE or FALSE if it's valid.

  • Can I create an xml that specifies element from 2 nested xsd's without using a prefixes?

    - by TweeZz
    I have 2 xsd's which are nested: DefaultSchema.xsd: <?xml version="1.0" encoding="utf-8"?> <xs:schema id="DefaultSchema" targetNamespace="http://myNamespace.com/DefaultSchema.xsd" elementFormDefault="qualified" xmlns="http://myNamespace.com/DefaultSchema.xsd" xmlns:xs="http://www.w3.org/2001/XMLSchema" > <xs:complexType name="ZForm"> <xs:sequence minOccurs="0" maxOccurs="unbounded"> <xs:element name="Part" minOccurs="0" maxOccurs="unbounded" type="Part"/> </xs:sequence> <xs:attribute name="Title" use="required" type="xs:string"/> <xs:attribute name="Version" type="xs:int"/> </xs:complexType> <xs:complexType name="Part"> <xs:sequence minOccurs="0" maxOccurs="unbounded"> <xs:element name="Label" type="Label" minOccurs="0"></xs:element> </xs:sequence> <xs:attribute name="Title" use="required" type="xs:string"/> </xs:complexType> <xs:complexType name="Label"> <xs:simpleContent> <xs:extension base="xs:string"> <xs:attribute name="Title" type="xs:string"/> </xs:extension> </xs:simpleContent> </xs:complexType> </xs:schema> ExportSchema.xsd: (this one kinda wraps 1 more element (ZForms) around the main element (ZForm) of the DefaultSchema) <?xml version="1.0" encoding="utf-8"?> <xs:schema id="ExportSchema" targetNamespace="http://myNamespace.com/ExportSchema.xsd" elementFormDefault="qualified" xmlns="http://myNamespace.com/DefaultSchema.xsd" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:es="http://myNamespace.com/ExportSchema.xsd" > <xs:import namespace="http://myNamespace.com/DefaultSchema.xsd" schemaLocation="DefaultSchema.xsd"/> <xs:element name="ZForms" type="es:ZFormType"></xs:element> <xs:complexType name="ZFormType"> <xs:sequence> <xs:element name="ZForm" type="ZForm" maxOccurs="unbounded" /> </xs:sequence> </xs:complexType> </xs:schema> And then finally I have a generated xml: <?xml version="1.0" encoding="utf-8"?> <ZForms xmlns="http://myNamespace.com/ExportSchema.xsd"> <ZForm Version="1" Title="FormTitle"> <Part Title="PartTitle" > <Label Title="LabelTitle" /> </Part> </ZForm> </ZForms> Visual studio complains it doesn't know what 'Part' is. I was hoping I do not need to use xml namespace prefixes (..) to make this xml validate, since ExportSchema.xsd has a reference to the DefaultSChema.xsd. Is there any way to make that xml structure valid without explicitly specifying the DefaultSchema.xsd? Or is this a no go?

  • Dynamic jQuery Validate error messages with AddMethod based on the element

    - by mcpDESIGNS
    Let's say I have a custom AddMethod to jQuery Validate like: $.validator.addMethod('min-length', function (val, element) { // do stuff // the error message here needs to be dynamic }, 'The field cannot be less than than ' + element.attr('data-min') + // it is within the closure, but it can't grab it ' length.'); I can't figure out a way to get the element variable in question, and get any values from it. What am I missing here?

  • Conditional value for ActiveRecord create method only

    - by Steve Wright
    I have a form where I have an administrator creating new users. The form uses the User model I created (login, password, first_name, etc...). For the last field on the form, I want to have a checkbox that doesn't need to be stored as part of the User record, but it is needed for the controller. This will control whether or not the newly created user will receive a welcome email or not. def create @user = User.new(params[:user]) if @user.save if @user.send_welcome_email UserMailer.welcome_email(@user).deliver end redirect_to(admin_users_url, :notice => "User #{@user.name} was successfully created.") else render :action => "new" end end In my view (haml) I am trying to access it like this: %p Send Welcome Email? = f.check_box :send_welcome_email I tried to make this an attr_accessible: :send_welcome_email but the controller does not recognize it. I get an undefined method 'send_welcome_email' for #&lt;User:0x00000100d080a8&gt; I would like it to look like this: What is the best way to get this working:

  • How to detect if a form input element of type file is empty

    - by Ankur
    I have some code which reads a file through a form field of type file <input type="file" ... /> I want to give the user another option of providing a url to a file rather than having to upload it as many are already online. How can I detect when this field is empty on the server side. I am using Apache Commons FileUpload FileItemStream item = iter.next(); name = item.getFieldName(); stream = item.openStream(); if(!item.isFormField()){ if(item.toString()!=""){ .... I need to detect when item is empty. The above code doesn't work, nor does using: if(item.equals(null)){ ....

  • How to Create A Document Type Definition

    - by DaveDev
    Hi Guys I've been creating a lot of my own custom attributes in my XHTML documents lately, and am aware that because they are custom attributes, they won't validate against the W3C standard. Isn't it true that I can specify my own DTD to make it validate? If so, can anyone tell me what's involved in doing this in an ASP.NET MVC app? Thanks Dave

  • Using the AutoComplete feature of ComboBox, while limiting values to those in the list?

    - by Schmuli
    In WinForms 2.0, a ComboBox has an Auto-Complete feature, that displays a custom Drop-Down list with only the values that start with the entered text. However, if I want to limit valid values to only those that appear in the ComboBox's list of items, I can do that by setting the DropDownStyle to DropDownList, which stops the user from entering a value. However, now I can't use the Auto-Complete feature, which requires user input. Is there another way to limit input to the list, while still allowing use of the Auto-Complete feature? Note that I have seen some custom solutions for this, but I really like the way the matching Auto-Complete items are displayed in a Drop-Down list, and sorted even though the original list may not be. EDIT: I have thought about just validating the entered value, i.e. testing user input if it is valid in, say, the TextChanged event, or even using the Validating event. The question then is what is the expected behavior? Do I clear their value (an empty value is also invalid), or do I use a default value? Closest matching value? P.s. Is there any other tags that I could add to this question?

  • PHP: File exists and is in a certain sub-directory

    I get a file path to a user file and I want to make sure that this path is to a valid existing user file and not to something bogus or a system file or something like that. I know I can use file_exists to check that it exists, but I'm not sure how I should make sure that the file is in a certain sub-directory...

  • Validate a subset of or only certain elements of an XML document?

    - by Gaurav Dadhania
    I have this XML file (some of them are HUGE - thousands of elements) and I'm trying to validate certain elements of this XML file using an XSD schema. For eg. dates, etc. Now, the problem is that XSD won't let me validate just certain sections of the document. It wants definitions for EVERYTHING - and that would be quite painful. What I would like to know is that is there a way to XSD work with only certain elements of the document? I've tried any and anyAttribute to no avail. If not, how would you do this? Is there a library/script that produces a schema corresponding to an XML document which I can then modify according to my needs? Thanks,

  • PHP contact form, am I doing it wrong?

    - by decimal
    I'm learning PHP and I'm trying to write a simple email script. I have a function (checkEmpty) to check if all the forms are filled in and if the email adress is valid (isEmailValid). I'm not sure how to return true checkEmpty funciton. Here's my code: When the submit button is clicked: if (isset($_POST['submit'])) { //INSERT FORM VALUES INTO AN ARRAY $field = array ('name' => $_POST['name'], 'email' => $_POST['email'], 'message' => $_POST['message']); //CONVERT ARRAY KEYS TO VARIABLE NAMES extract ($field); checkEmpty($name, $email, $message); function checkEmpty($name, $email, $message) { global $name_error; global $mail_error; global $message_error; //CHECK IF NAME FIELD IS EMPTY if (isset($name) === true && empty($name) === true) { $name_error = "<span class='error_text'>* Please enter your name</span>"; } //CHECK IF EMAIL IS EMPTY if (isset($email) === true && empty($email) === true) { $mail_error = "<span class='error_text'>* Please enter your email address</span>"; //AND IF IT ISN'T EMPTY CHECK IF IT IS A VALID ONE } elseif (!isValidEmail($email)) { $mail_error = "<span class='error_text'> * Please enter a valid email</span>"; } //CHECK IF MESSAGE IS EMPTY if (isset($message) === true && empty($message) === true) { $message_error = "<span class='error_text'>* Please enter your message</span>"; } } // This function tests whether the email address is valid function isValidEmail($email){ $pattern = "^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$"; if (eregi($pattern, $email)) { return true; } else { return false; } } I know I shouldn't be using globals in the function, I don't know an alternative. The error messages are display beside each form element.

  • Best way to validate currency input?

    - by Abe Miessler
    I have created the TextBox and CompareValidator below which I thought would allow input in the following forms: 5 5.00 $5.00 Unfortunately it's not allowing the version with the dollar sign in it. What is the point of doing a type check against currency if you don't allow the dollar sign? Is there a way to allow this symbol? <asp:TextBox ID="tb_CostShare" runat="server" Text='<%# Eval("CostShare", "{0:$0.00}")%>' CausesValidation="true" /> <asp:CompareValidator ID="vld_CostShare" runat="server" ControlToValidate="tb_CostShare" Operator="DataTypeCheck" Type="Currency" ValidationGroup="vld" ErrorMessage="You must enter a dollar amount for 'Cost Share'." />

  • MySQL: How to check if a string is a valid DATE, TIME or DATETIME

    - by Svish
    When I try to put a value into a DATE field which is invalid, MySQL seems to use 0000-00-00 instead. Is there a way I can do this "check" without updating a DATE field? And to do it from for example PHP? Like, is there a way I can query the MySQL server and ask "Hey, is this DATE, TIME or DATETIME valid to you?" Or is there maybe an even better way of doing it?
