[Shahbaj Maner, modifié il y a 10 années.]

Hello,
I am using checkboxes for hobbies..But i am getting null in action class. please help me how to get that values in action class?
This my .jsp page code

			<input type="checkbox" name="hobbies" value="1"> Art
			<input type="checkbox" name="hobbies" value="2"> Music
			<input type="checkbox" name="hobbies" value="3"> Sports
            <input type="checkbox" name="hobbies" value="4"> Trekking

This my action class where I want that values

        public void test (ActionRequest actionRequest,
        	ActionResponse actionResponse) throws IOException, PortletException {
                String[] hobbiesList =ParamUtil.getParameterValues(actionRequest,"hobbies");
                String[] hobibiesList1 = actionRequest.getParameterValues("hobbies");
        }

Both of these are returning no values...Please help me...
Thanks in advance

Per portlet spec you need to namespace your parameter name. Liferay 6.2 now enforces that although there's a setting to turn the old behavior on but I can't remember what it was off the top of my head and it's better to namespace them always.

It's all documented in the developer guide's section 3 - Passing information from action phase to render phase. The details are under using portlet namespacing.

For the lazy: This is what you put on your portlet's liferay-portlet.xml to allow non namespaced parameters:

<requires-namespaced-parameters>false</requires-namespaced-parameters>

hey man why would you teach the lazy way?
i'm having the same issue right now with a biggie portlet....
and i do need these namespace parameters.
if you could share a quick thing on how to achieve the real goal...

the guy up there had tried :

String[] hobbiesList =ParamUtil.getParameterValues(actionRequest,"hobbies");
String[] hobibiesList1 = actionRequest.getParameterValues("hobbies");

and then he got an empty array as result.
i myself am facing this too.
So, i'd like, if you could, you to guide us with the scenario.. or maybe we need to handle this actionRequest in a different way?
anyway, any advice would always be greatly taken.
peace!

Hi Javier,

If you really need the namespaced parameters, use the following for all the html elements
i. with aui html fields e.g. <aui:input name="test" /> OR
ii with normal html fields e.g. <input type="text" name="<portlet:namespace/>test">

Also make sure your Portlet Class is registered in portlet.xml within the <portlet-class>(I did this mistake earlier).

<portlet-class>com.xyz.test.TestPortlet</portlet-class>

hi ho, Tanweer.
Thanks for the quick reply.

So far i've tryed these without success.

<aui:input type="checkbox" class="case" name="caseapp[]" value="<%= String.valueOf(sContent.getPrimaryKey()) %>" />

and

<aui:input type="checkbox" class="case" name="caseapp" value="<%= String.valueOf(sContent.getPrimaryKey()) %>" />

note these two have the "name" property set and both are "aui" components.
However, on the action class i get to the method ( i put the portlet-class correctly ), i find empty parameters.

i try to catch these with the following:

String[] arrString = ParamUtil.getParameterValues(actionRequest, "caseapp");
String arrTry = ParamUtil.getString(actionRequest, "caseapp");
String[] arrString2 = ParamUtil.getParameterValues(actionRequest, "caseapp");

yet the result is the same, i know i am doing something wrong i just figure out what.
any idea besides taking namespace of parameters????

Hi Javier,

As a test I did below and it works as expected.I hope your form uses post method.

<form method="post" id="fm" name="fm" action="<portlet:actionURL />">
    <aui:input type="checkbox" name="caseapp" value="123" />
    <aui:button type="submit" value="Save" />
</form>

final String caseapp = ParamUtil.getString(actionRequest, "caseapp");
        System.out.println(caseapp);

Yup, just to clarify this is what i used.

<aui:form name="frm" method="POST" action="<%= oUrl.toString() %>">  
</aui:form>


<!--  daaa daaa  -->
<div id="panel">
	<section>
	<div>
<input type="checkbox" class="Checkbox" name="caseapp" value="<%= String.valueOf(sIndicador.getPrimaryKey()) %>" title="" <%="(isAlreadyRegistered(iCut).size()"> 0)?"Checked":"" %&gt;  /&gt;	
			</div>
		&lt;%} %&gt;
	</section>
</div>
[b]<aui:input id="resulttxt" type="hidden" name="resulttxt" />[/b]

<aui:button onclick="collectChk();" id="clickmepri" value="Grabar" type="submit"></aui:button>

and to the bottom i added

 
$('#<portlet:namespace />resulttxt').val($('.Checkbox:checked').map(function() {
	    return this.value;
	}).get().join(', '));
}

then i just catch the "resulttxt" in the action method.

thank you for the time
