Re: [xwiki-users] Hi there! How to create validations using regular expressions?

Hi, You use the class editor to define your class, its properties and validation regex for certain properties. That is just the first step. Now you need to create a sheet [1] for your class in order to be able to display documents having objects defined by your class. Inside the sheet is where you do the display of your fields and where you can also trigger the validation and display validation errors. The link you gave about validation might contain some deprecated notions, but generally the idea is the same. Here is a rough example of how to use that input inside your sheet: {{velocity}} Errors: $context.validationStatus.errors {{html}}<input type="hidden" name="xvalidate" value="1" />{{/html}} Name: $doc.your_name {{/velocity}} The first line (after the velocity macro call) prints validation errors, if any, the second line is the xvalidate invisible marker that marks the inline editor's form as validating its inputs (based on the validation regex of each field defined in the class) and the third line is just displaying the "your_name" field from the object inside the current document. If you go in (inline) edit mode, the sheet will show an input for the "your_name" field. You enter data and press save. If the data does not validate, the page will not be saved but it will be reloaded and showing the validation error. To answer your question, yes, you do need to have the xvalidate input inside your class sheet, otherwise the standard XWiki save button for the inline edit mode will not know if to enable or not validation. If it is not there, it will just save whatever you enter in the fields. If you want javascript validation just follow the instructions [2] at the bottom. The example you find there is not a clean one, since you should not use inline javascript but a JavaScriptExtension [3] and instead of those html form elements (input, label, etc) you can just do $doc.<fieldName> and use "<className>_<objectNumber>_<fieldName>" (e.g. "Main.Class_0_your_name") as id in the javascript code. Hope this helps, Eduard ---------- [1] http://extensions.xwiki.org/xwiki/bin/view/Extension/Sheet+Module [2] http://platform.xwiki.org/xwiki/bin/view/DevGuide/Creating+a+form+with+vali… [3] http://platform.xwiki.org/xwiki/bin/view/DevGuide/SkinExtensionsTutorial#HM… On Thu, Aug 7, 2014 at 10:35 AM, O.J.
