Code:
$data = array(

               'title' => $title,

               'name' => $name,

               'date' => $date

            );

$this->db->where('id', $id);

$this->db->update('mytable', $data);

// Produces:

// UPDATE mytable

// SET title = '{$title}', name = '{$name}', date = '{$date}'

// WHERE id = $id

Hi,

This is how I would do it:
In your view: You name your input checkboxes 'id_'.$id
In your controller: for each selected checkbox you explode the post key and do the update with the $exploded[1] value.

Greetings,

Controller Contacts

Code:
class Contacts extends controller{

    function Contacts(){

        parent:: Controller();

        $this->load->database();

        $this->load->model('contacts_model');

        $this->load->helper('form');

        $arrayid= $this->input->post('edit');

        if(count($arrayid)){

            for($i=0;$i<=count($arrayid); $i++){

            //call model to compare

            $data['query']= $this->contacts_model->insertlist();

            if($data['query']){

                redirect('contacts/index');

                }

        }

    }

Views: Contacts_view: it is used for inserting and popping the data in the table

Code:
&lt;body&gt;

        <p align=center>&lt;?=$title ?&gt;</p>

        <hr align= "center" width="650px">

Allright.
I'm going to suggest a way to make this work. This is just a suggestion. Anybody who has a better approach, is very welcome to correct me, I want to learn, but for now I would handle it like this.

I would update my model a bit:

I wouldn't hardcode the $_POST in insertlist()

Code:
function insertlist($values){

        $query = $this->db->insert('contacts',$_values);

        return $query;

        }

I would replace poplist() and compareID() with a function getcontacts or something simular

Code:
getcontacts($id = null)

{

  $this->db->orderby('id','DESC');

  //check for the id here (could be a single value or an array)

  //add the where clause if $id

  $return the result

  // this way you can use it to get all or some of the contacts

}

I would make a view to add / edit a single contact and a different view to edit multiple contacts.

In my controller i would have a method contact() and contacts()
something like this:

Code:
public function contact($id = null)

{

//set your validation rules

if($this->validation->run())

  {

  if($id){ // should contain check if its a real contact id & then you could update your contact information

  }elseif(!$id){ //insert your contact information}

  //if succesfull insert or update -> redirect or do whatever you want

}else{

 // load your contact form here.

 if($id) // get the contact information and pass it to the contact form as standard input (after submission form fields should use validation input as value.

}

}

btw i have an input helper (saw it on the forum around here somewhere) that checks if I have $this->validation->input_name. If I don't have that, it returns a standard input i passed throught in the controller

I don't quite get what you are asking.
If you want to use $this->input->post('contact_name') just use it wherever you need it, or assign it to a variable. ($var = $this->input->post('name') Wink

if you explode your input: $contact_name = explode('_',$this->input->post('contact_name'));
you can use the result like this: $contact_name[1] //(or whatever part you might need)

btw you're not stressing me. You're only asking questions. If I have the time and a possible answer, I'm glad to try and help.

[eluser]Mellis[/eluser]
Were you able to solve your problem?

08-19-2008, 07:04 PM

[eluser]eironotics[/eluser]
yeah thanks mellis.

I was able to store all the values in <input> tag in an array.
then i use a foreach loop to compare the id into the table.

thanks,
