Change the input field name into an array:

Code:
// change this

&lt;input type="checkbox" name="rdindex1" value="&lt;?=$primeno[$i];?&gt;"/&gt;

// to this

&lt;input type="checkbox" name="rdindex1[]" value="&lt;?=$primeno[$i];?&gt;"/&gt;

Then when you read it in your controller the value passed back in $this->input->post('rdindex1') will be an array you can loop through.

in the page where you submit, just make a loop to check the checked box

Code:
&lt;?

   for($i = 0; $i < sizeof($primeno); $i++){

      if(isset($primeno[$i]))

           //primeno[$i] is checked

   }

&lt;input type="checkbox" name="rdindex1[]" value="&lt;?=$primeno[$i];?&gt;"/&gt;

the javascript only works if the

Code:
name="rdindex1"

what should i do?
this is my javascript for checking all the checkbox:

Code:
function checkallBox()

{

    for (i=0;i<document.forms['formkeywords'].rdindex1.length;i++)

    {

        document.forms['formkeywords'].rdindex1[i].checked=true;
