Answer 1

Try this,
$(".case").on('click',function(){
var chk=$('.case:checked').length ? true : false;// if length is > 0 then return true
$('#selectall').prop('checked',chk);// if chk true then check the selectAll checkbox
});
Take a look on fiddle
You need to create a form submit and call the function of controller on form submit
# Your Controller Function
function del($reg_id) //delete content
{
$this->load->helper(array('form','url'));
$this->load->model('registration');
$checkbox=$this->input->post('checkbox');# Using Form POST method you can use whatever you want like GET
$reg_id=$this->input->post('reg_id');# Using Form POST method
$regId_array=array();
foreach($checkbox as $key=>$checked)
{
if($checked!==FALSE)
$regId_array[]=$reg_id[$key];
}
if(!empty($regId_array))# array of checked reg_id to delete
{
$query=$this->registration->del($checkbox,$id);# use del here not delete as your model says
}
else{
die('No checkbox selected!!!');
}
$data['query']=$this->registration->cr_getall();
$this->load->view('vw_register',$data);
}
# Your Model Function
public function del($reg_id)
{
$this->load->database();
$this->db->where_in('reg_id', $reg_id);# delete all reg_id in $reg_id array variable
$this->db->delete('tbl_contctform');
if($del)
{
return $del;
}
else
{
return false;
}
}
And your View should be like,
<?php
foreach($query as $row)
{
?>
<tr><td>
<input name="checkbox[]" class="case" type="checkbox" />
<input name="reg_id[]" type="hidden" value="<?php print $row->reg_id; ?>">
</td></tr>
<?php
}
?>

I changed my View,Controller,Model like this..now it working properly
View:
<form name="forms" action="delete_checkbox/" method="post">
foreach($query as $row)
{?>
<tr>
<td><input type="checkbox" name="forms[]" id="forms[]"
value="<?php print $row->reg_id; ?>"/>
</tr?
<?php } ?>
Controller:
function delete_checkbox() {
$dat = $this->input->post('forms');
for ($i = 0; $i < sizeof($dat); $i++) {
print_r($dat[$i]);
$this->load->model('registration');
$this->registration->delete_check($dat[$i]);
}
redirect('viewreg/showall', 'refresh');
}
It works!!
