I have a quite simple problem, I have a form generated by symfony and mapped to object but on form submit there is an action of jquery which appends few fields to the form. How can I access these values in symfony? I don't see it in raw $_POST array, it's not in $request value. thanks
You can inspect your request variables, using symfony 2.3, like this:
var_dump($this->getRequest->request->all);

I need to do the thing like this (setting ActionForm attribute):
<html:form action="Link.do?method=editNews">
<html:hidden property="idNews" value="${news.newsMessage.idNews}" />
<html:submit value="EDIT"/>
</html:form>
But in <html:link> or regular a-href tag. So I don't want this parameter to apear in my link as a request parameter. Is it possible?
P.S. idNews is the parameter in my ActionForm class and it has setter and getter.
No, it's not possible. A link performs a GET request, and the only way for a GET request to send information to the server is to use request parameters, which appear in the URL.
The only thing you can do is to have your link invoke a JavaSCript function which submits a hidden form using POST. But it's ugly.
Why do you fear by making the parameter visible in the URL? Are you aware that anybody can view the source of your HTML page and see the hidden field here?
Is there any chance to get the html content (mime) from a rich text component without any datasource. I would like to grab the content from the field like this. getComponent("FieldName").value but this dosen't work.
thanks.
You can bind the control to a scoped variable; for example, #{viewScope.comments}. You can then retrieve the submitted value from the scope instead of from the component itself; for example, viewScope.get("comments").
Alternatively, you can set a dataContext variable to a JS expression, e.g. <dataContext var="richText" value="#{javascript:return {value:""};}" />. Then you can bind the control to #{richText.value} and retrieve it via the same expression.
And, of course, you could define a managed bean and bind the control to one of its properties. This option provides the most flexibility, but isn't quite as simple as the other two options above.
The solution for my problem is
getComponent("FieldName").getValue()
thanks for your help.
I am currently evaluating Wicket and I am trying to figure out how things work.
I have a question regarding form submit and panels (or other components).
Imagine a custom wicket panel which contains a text field, doing as-you-type validation using ajax. This panel is added to a form.
How can the Panel react a form submit (let's say because javascript/ajax is unavailable)?
I am currently only aware of one solution: calling a panel's method inside the Form onSubmit() method. But this seems not like a "reusable" approach here, because I have to add boilerplate code to every form's onSubmit() which contains the panel (and every developer which use the panel must know this).
So here comes my question: Is there any way that a Panel/Component can "detect" a form submit in some way? Or is there any other solution beside this?
Thank you.
Make your panels implement org.apache.wicket.markup.html.form.IFormModelUpdateListener, and the updateModel() method should be called when the containing form is submitted and passes validation.
There's a good example of code using this by one of the wicket authors at the Wicket In Action blog.
Well, you could simply do the following:
Panel{
Form{
onSubmit(){
Panel.this.onSubmit();
}
}
protected void onSubmit(){}
}
...
This means that any panel that extends your panel need only override the onSubmit and the form no matter what it is in html will call that method. That way you can extend the panel and only override one method for each form.
With regard to form components, the framework handles it for you transparently. Forms are aware of any child form components, even if they haven't been added directly to the parent form.
I would have a Form inside that Panel. This way, you can reuse that Panel without requiring an external Form. As Forms can not be nested inside each other in HTML, Wicket will swap the inner Form(s) into 's transparently, but will make sure that each of the inner Forms takes part of the form processing (validation,..).
You can override the OnSubmit() function of the Form in your Panel. Wicket will call it for you.
what do you mean by "react"? I have only started recently with Wicket, but FWIK, form submit updates the model of a component, and then it calls onSubmit(), which you can override to take special actions beyond that. See Wicket in Action, chapter 6.
After that, the page (and it's components) get re-rendered, using the updated model, so basically, they really "react" on a submit, with quite few lines of code.
For your mentioned case with Component in a Form, have a look at the CompoundPropertyModel.
Implementing IFormSubmitListner and IFormModelUpdateListener shall call the respective methods during a form submit.
However, if you want to do some processing after form submit, I'm afraid you have no choice but to write some boilerplate code yourself.
Does anyone know the syntax, or the way to redirect a sharepoint "New Item Form" to a URL and pass values from the form as parameters in the URL?
So if the form as a "lastname" field, I would want the redirect to be something like http://path_to_other_page?name=lastname
I know I need to use something like:
onclick="javascript: {ddwrt:GenFireServerEvent(concat('__commit;__redirect={path_to_other_page.aspx?name=',/dsQueryResponse/Rows/Row/#LastName))}"
Except that's not working for me - I think the "/dsQueryResponse/Rows/Row/#LastName" is not correct - I was just trying to guess from other posts I had seen here...
Anyone?
That looks like something that would work on an edit form rather than a new form - that data is loaded when the page is loaded, not when it is submitted. To get the data in javascript you will need to access the textbox directly - jquery may be helpful.
I think you can use the SharePoint's build in Modal dialog (http://msdn.microsoft.com/en-us/library/ff410058(v=office.14).aspx). Within the modal dialog, you can callback function that will get the parameters from the form page.
i have master-content page scenario.I have a link button on content page. that redirects to other page. but with redirection it carrying the parameters. I want to hide this querystring parameters .I tried with POST() in Form tag of master page . but that does not affecting. What have to do ?
There are many ways to carry values from one page to the next. You could store the values in some Session type container, or add them as hidden fields.
If you want a ugly way, you could use a good old frameset.
POST is the answer, but we'll need some code to help more effectively
