Count post data in a CodeIgniter controller - php

Question

I have five text fields that are not mandatory. Sometimes enter data in one field, sometimes 2 or 3 or 4 or 5. I have to count this data:
$sib1=$this->input->post(sib1);
$sib2=$this->input->post(sib2);
$sib3=$this->input->post(sib3);
Like this, I want to count this. Now 3

Answer 1

You can use a for loop with length = number of text fields. Put it to the database afterwards. sibcount is the number of filled entries.
$data = array();
$length = 5;
$sibcount = 0;
for ($i=0;$i<$length;$i++) {
$entry = $this->input->post("sib".$i);
if (!empty($entry)) {
$data["sib".$i] = $entry;
$sibcount++;
}
}
$data["sibcount"] = $sibcount;
// use in controller or model
if (!empty($data))
$this->db->insert('mytable', $data);

Answer 2

this is way to do it:
Take an array $arr=array();
$arr['sib1']=$this->input->post("sib1",true);
$arr['sib2']=$this->input->post("sib2",true);
$arr['sib3']=$this->input->post("sib3",true);
$arr['count']=count($this->input->post($arr)); //this will count your post
$result = $this->Model_name->model_function($arr);
In Model
function model_function($arr)
{
$this->db->insert('tbl',$arr);
if ($this->db->affected_rows() > 0) {
return true;
} else {
return false;
}
