[S2] Pre-populating Checkboxes

Hello,

I'm new to Struts 2 and I was wondering how to pre-populate checkboxes
with values from a database (or even hard-coded values). I am iterating
through an arraylist of hashmaps (description, type_cd) to create the
checkboxes in the form. I then create a string array with the values
from a database to pre-populate, but it's not working.

* When the checkboxes are checked and the form is submitted, I am able
to capture the values (String array) properly.

JSP:
<s:iterator value="all_type_codes">
<s:checkbox name="type_cd" fieldValue="%{type_cd}"/>
<s:property value="description"/>
 
</s:iterator>

Action Page:
public String[] getType_cd() {
return type_cd;
}
public void setType_cd(String[] type_cd) {
this.type_cd = type_cd;
}

// this is a test
type_cd = new String[3];
type_cd[0] = "EQ";
type_cd[1] = "SF";
type_cd[2] = "SS";

Any help would be greatly appreciated!

Re: [S2] Pre-populating Checkboxes

Hi,

This is how i do it, i have implemented the prepreable interface in my
action and in prepare method, i populate the list i wanted to display in
as check box values.

eg:-

private List skills;

public List getSkills() {
return skills;
}

public void prepare() throws Exception {
skills = new ArrayList();
skills.add("Java");
skills.add("C#");
skills.add("Spring");
skills.add("Struts 2");
}

in jsp i have this tag and which will render 4 check boxes.

<s:checkboxlist name="skill" list="skills"/>

Thanks,

Nuwan

RE: [S2] Pre-populating Checkboxes

Hi,

Thank you very much for your assistance, but I am already able to
display the checkboxes. I guess my question wasn't very clear. I need
to know how to redisplay the checked boxes a user selected in a previous
session. So if there are five check boxes and the user selects three of
them and submits the form, how do I automatically check the three boxes
when the user returns the next day? It appears that returning a string
array with the users selections is not working.

Thanks,
Dave

If I have understood your question right, you need to persist user selection (say in a database). What you are asking extends way beyond browser session or reqeust scope.

RE: [S2] Pre-populating Checkboxes

In reply to this post by David Ogasawara

In your original code you don't do anything to specify whether or not the current value matches on of the values in the user's current selections--not sure what magic you were expecting.

The <s:checkboxlist...> tag [1] accepts both value and selection choices; it may be sufficient for your needs. If you're going to do the value/checkbox iteration by hand then you also need to implement the logic for determining if it should be checked initially.

RE: [S2] Pre-populating Checkboxes

In reply to this post by Struts Two

Hi,

Yes, I am saving the results in a database. When the user returns, I
query the database and place the results into a string array. I am
unable to get this array to repopulate the check boxes the user
previously selected.

Thanks,
Dave

RE: [S2] Pre-populating Checkboxes

This is exactly what I needed. I was avoiding checkboxlist because I
wanted the options to be displayed vertically, but it looks to be the
only option unless I add more code to determine if a checkbox was
selected.

Thank you, everyone, for your help!!!

Re: [S2] Pre-populating Checkboxes

It is remarkably easy to extend the 'simple' or 'xhtml' themes to make
s:checkboxlist display vertically. Here's how I did it:

In the root of my web code I have a 'template' folder. Within 'template' I
have a folder named 'my'. Inside 'my' I have checkboxlist.ftl.

checkboxlist.ftl looks like this (minus the license boilerplate):

<#assign itemCount = 0/>
<#if parameters.list?exists>
<@s.iterator value="parameters.list">
<#assign itemCount = itemCount + 1/>
<#if parameters.listKey?exists>
<#assign itemKey = stack.findValue(parameters.listKey)/>
<#else>
<#assign itemKey = stack.findValue('top')/>
</#if>
<#if parameters.listValue?exists>
<#assign itemValue = stack.findString(parameters.listValue)/>
<#else>
<#assign itemValue = stack.findString('top')/>
</#if>
<#assign itemKeyStr=itemKey.toString() />
<tr><td><input type="checkbox" name="${parameters.name?html}"
value="${itemKeyStr?html}" id="${parameters.name?html}-${itemCount}"<#rt/>
<#if tag.contains(parameters.nameValue, itemKey)>
checked="checked"<#rt/>
</#if>
<#if parameters.disabled?default(false)>
disabled="disabled"<#rt/>
</#if>
<#if parameters.title?exists>
title="${parameters.title?html}"<#rt/>
</#if>
<#include "/${parameters.templateDir}/simple/scripting-events.ftl"
/>
<#include "/${parameters.templateDir}/simple/common-attributes.ftl"
/>
/>
</td><td><label for="${parameters.name?html}-${itemCount}"
class="checkboxLabel">${itemValue?html}</label></td></tr>
</@s.iterator>
<#else>
 
</#if>

This is probably not the ideal way to do this, but it works great for me.

class="checkboxLabel">${itemValue?html}</label>

Or use the "css_xhtml" theme, which IIRC just spits out checkboxes and labels with no other markup.

Or modify <s:checkboxlist...>'s template, which might be more appropriate if you need the functionality across your application.
