 ====== Creation of a news form ====== ====== Creation of a news form ======
  
-A form system, jForms, is under development and will be available in Jelix 1.0 beta2. jForms deals with received data from forms server side and client side at the same time (HTML, XUL, or web services) : creation, save, data check, etc. +A form system, jForms, is available in Jelix, but we will see it in a next chapter.
-This part is more or less operational in Jelix 1.0 beta1 but remains however experimental. jForms will be also handle the generation of HTML, XUL or other forms in the templates (starting from jelix 1.0 beta2).+
  
-While waiting, you will have to use a more "traditional" method :-)  +For the moment, we're going to see how to deal with forms in a "traditionnal" way. We will to create a form in order to record some new news.

-The goal of this chapter, will be to create a form in order to record some new news.+

-Very classical, put aside the template tag {jurl}. In Jelix, you will avoid putting urls directly in the templates or the actions, for ease of maintenance and evolution reasons. The URL system of Jelix enables you to centralize all the urls in the jelix config or a urls.xml file (all depends on the URL engine used). The jUrl object and the tag {jurl} enable you to obtain a URL by giving only the name of the action and eventually the parameters.

 +We could have used the tag {jurl} also in <form> tag, but if the URL contains parameters (as is the case here with module and action), it is best to put them in hidden fields. However, if we changed the configuration on the mapping url, it is not forced there is always these parameters. Also being used in conjunction plugins {formurl} and {formurlparam} who will themselves decide what to put in the attribute "action", and what should be put in hidden fields.

 +Here then, we state that the form will be submitted to URL of the default:createsave action.
