{
//$this->db->where('id', $id);
$this->db->where('taskid', $taskid);
$this->db->update(MILESTONE, $data);
}
Following is my View (For lop is here)
<?php
foreach ($result as $milestone_row) {
?>
<tr id="<?php echo $milestone_row->id; ?>">
<?php
if ($is_master_admin) {
if ($i > 1) {
if ($milestone_row->userid == $userid) {
} else {
$userid = $milestone_row->userid;
echo $milestone_row->usertitle;
}
} else {
$userid = $milestone_row->userid;

?>
<b><u>Approved Hours:-</u></b>
<input style="height:14px;font-size:10pt; width: 33px" type="text" id="hours" name="approvedhrs" data-required="1" value="<?php echo $milestone_row->esthours; ?>" placeholder="Hours" onkeypress="return isNumberKey(event)" />
<input style="height:14px;font-size:10pt; width: 33px" type="text" id="minutes" name="approvedmins" value="<?php echo $milestone_row->estmin; ?>" data-required="1" placeholder="Minutes" onkeypress="return isNumberKey(event)" />
Edit
<?php echo " | ";?>
Delete
<!--<span class="datetime">at <?php //echo $milestone_row->createddate; ?></span> -->
</span>
</div>
</li>
Followinf is myController
function approvedHrs($taskid)
{
if ($this->session->userdata('logged_in')){
$session_data = $this->session->userdata('logged_in');
$id = $session_data['id'];
$username = $session_data['username'];
$is_master_admin = $session_data['master'];
$imagethumb = $session_data['imagethumb'];
$pendingbug = $this->bugmodel->getBug($id, $is_master_admin);
$pendingtask = $this->taskmodel->getTask($id, $is_master_admin);
$data = '';
$data = array(
'approvedhrs' =>$this->input->post('approvedhrs'),
'approvedmins'=>$this->input->post('approvedmins')
);
// print_r($data);
// exit;
$result = $this->milestonemodel->approvedHrs($taskid,$data);
// $this->session->set_userdata('msg', $result);
redirect('task', 'refresh');
}
else
{
redirect('login', 'refresh');
}
}
When i use array like this it gives me following error
PHP Error Occured :Message: Array to string conversion
Database Error : Unknown column 'Array' in 'field list'
UPDATE milestone SET approvedhrs = Array, approvedmins = Array WHERE taskid = '17'

Answer 1

You should simplify your code like this
$post = $this->input->post();
$data['approvedhrs'] = $post['approvedhrs'];
$data['approvedmins'] = $post['approvedmins'];
print_r($data);
$result = $this->milestonemodel->approvedHrs($taskid,$data);
You should make sure $post['approvedhrs'] and $post['approvedmins'] do not have arrays. They could contain array when defined in the form like this
<input type='text' name="approvedhrs[]" />
<input type='text' name="approvedmins[]" />
EDIT
As you are making inputs inside loops there fore both approvedhrs and approvedmins are posted as array. Which is causing problem in updating.
EDIT
You should make the inputs in your loop like this
<input type='text' name="approvedhrs[]" />
<input type='text' name="approvedmins[]" />
Make hidden inputs for row id and task id
<input type='hidden' name="rowid[]" />
<input type='hidden' name="taskid[]" />
<input type='text' name="approvedhrs[]" />
<input type='text' name="approvedmins[]" />
And now php
$post = $this->input->post();
$data['approvedhrs'] = $post['approvedhrs'];
$data['approvedmins'] = $post['approvedmins'];
for($i=0;$i<count($data['approvedhrs']);$i++){
$update_data['approvedhrs'] = $data['approvedhrs'][$i];
$update_data['approvedmins'] = $data['approvedmins'][$i];
$taskid = $data['taskid'][$i];
print_r($update_data);
$result = $this->milestonemodel->approvedHrs($taskid,$update_data);
unset($update_data);
unset($taskid);
}

Answer 2

As you are passing array of data to update, you can use update_batch mentod.
In your controller, prepare the data as below.
$k= 0 ;
$data = array();
$aphrs = $this->input->post('approvedhrs'); // returns array
$apmis = $this->input->post('approvedmins'); //
foreach($aphrs as $hrs)
{
$data[] = array(
'approvedhrs' =>$hrs,
'approvedmins'=>$apmis[$k]
);
$k++;
}
// call your model function
$result = $this->milestonemodel->approvedHrs($taskid,$data);
In your model function: add update_batch method. So no need to call update method in forloop.
for update_batch, check this tutorial.

View
<input type='hidden' name="milestoneid[]" value ="<?php echo $milestone_row->id ?>" />
<input type="text" id="hours" name="approvedhrs[<?php echo $milestone_row->id ?>][]" value="<?php echo $milestone_row->esthours; ?>"/>
<input type="text" name="approvedmins[<?php echo $milestone_row->id ?>][]" value="<?php echo $milestone_row->estmin; ?>"/>
Controller
function approvedHrs($taskid) {
if ($this->session->userdata('logged_in')) {
$session_data = $this->session->userdata('logged_in');
$id = $session_data['id'];
$username = $session_data['username'];
$is_master_admin = $session_data['master'];
$imagethumb = $session_data['imagethumb'];
$pendingbug = $this->bugmodel->getBug($id, $is_master_admin);
$pendingtask = $this->taskmodel->getTask($id, $is_master_admin);
$data = array();
$milestoneIDs = $this->input->post('milestoneid');
$approvedhrs = $this->input->post('approvedhrs');
$approvedmins = $this->input->post('approvedmins');
foreach ($milestoneIDs as $milestoneID) {
$data = array(
'approvedhrs' => isset($approvedhrs[$milestoneID]) ? $approvedhrs[$milestoneID] : '',
'approvedmins' => isset($approvedmins[$milestoneID]) ? $approvedmins[$milestoneID] : '',
);
$this->milestone_model->approvedHrs($milestoneID,$data);//change this model name as per you use
unset($data);
}
redirect('task', 'refresh');
} else {
redirect('login', 'refresh');
}
}
Model
function approvedHrs($milestoteid, $data) {
//$this->db->where('id', $editid);
$this->db->where('milestoteid', $milestoteid);
$this->db->update(MILESTONE, $data);
}
