[SOLVED] Foreach with implode comma

If it's only about the text value, why don't you assign that as the value attribute of the checkbox?

PHP Code:

<input type="checkbox" name="check_list[]" value="love">love<br> 


If you need both the number and the text, I would suggest getting the id's and names from your database and put them into an array (in your controller):

PHP Code:

$info = array();
$query = $this->db->query("SELECT id,text_name FROM info");
foreach ($query->result() as $i) {
   $id = $i->id;
   $info[$id] = $i->text_name;
}
// result of this is: $info[1] = 'love', $info[2] = 'heart' etc.

$tags = $this->input->post('check_list');
$selected = array();
foreach ($tags as $t) {
    $selected[] = $info[$t];
}
$endresult = implode(',' , $selected);
// result of this: the "names" of the selected textboxes, seperated by comma's, so no comma after the last one.
