Getting multiple checkboxes/checkbox group values in JSP.

In this post, we look that how can get the multiple checkbox/checkbox group values using JSP.

So first craete multiple checkboxes:-

<form id="" action="get_choice.jsp" method="post">

<input name='cid' type='checkbox' value='value1' />

<input name='cid' type='checkbox' value='value2' />

<input name='cid' type='checkbox' value='value3' />

<input name='cid' type='checkbox' value='value4' />

</form>

Now where we want to recieve these values (in my case it is get_choices.jsp)

In String array get these values-

String[] cid=request.getParameterValues("cid");

if(cid!=null)

{

for(int i=0;i<cid.length;i++)

{

out.print(cid[i]);

}

}

You can also store these values in different variables for further processing like-

String[] cid; String ch1,ch2,ch3;

cid=request.getParameterValues("cid");

if (cid != null)

{

for(int i=0;i<cid.length;i++)

{

if(i==0)

ch1=cid[0];

if(i==1)

ch2=cid[1];

if(i==2)

ch3=cid[2];

}

}
