Change the input field name into an array:

Code:

// change this
<input type="checkbox" name="rdindex1" value="<?=$primeno[$i];?>"/>

// to this
<input type="checkbox" name="rdindex1[]" value="<?=$primeno[$i];?>"/>

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:

<?
   for($i = 0; $i < sizeof($primeno); $i++){
      
      if(isset($primeno[$i]))
           //primeno[$i] is checked
   }
?&gt;

i can't get it on how to use javascript to check all or uncheck the checkboxes using this name with brackets

Code:

<input type="checkbox" name="rdindex1[]" value="<?=$primeno[$i];?>"/>

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;
                                                                       }
}

Why do you need to process it in JavaScript?

[eluser]basty_dread[/eluser]
just like in yahoo mail. there is one checkbox that checked all the checkboxes. and when it uncheck the checkboxes... and when you press delete it will delete all the checked items.
