insert batch data array? - php

Question

I want insert following data by insert_batch as in following example in database table (mysql):
HTML:
<input name="u_id[0][0]" value="76">
<input name="un[0][0]" value="1">
<input type="text" name="ue[0][0]" value="11">
<input type="text" name="up[0][0]" value="111">
<input name="u_id[1][0]" value="77">
<input name="un[1][1]" value="2">
<input type="text" name="ue[1][1]" value="22">
<input type="text" name="up[1][1]" value="222">
<input name="un[1][2]" value="3">
<input type="text" name="ue[1][2]" value="33">
<input type="text" name="up[1][2]" value="333">
PHP:
$u_id = $this->input->post('u_id');
$un = $this->input->post('un');
$up = $this->input->post('up');
$ue = $this->input->post('ue');
$data = array();
foreach ($un as $idx => $name) {
$data[] = array(
'u_id' => $u_id[$idx],
'un' => $un[$idx],
'up' => $up[$idx],
'ue' => $ue[$idx],
);
};
$this -> db -> insert_batch('units', $data);
I want insert they as this:
How should change php code and html code? what do i do?

Answer 1

I am assuming you are using CodeIgniter and that the name of the database table that you want to insert to is called 'units' and that its 'id' column is autoincrement.
I am basing off my solution from CodeIgniter User Guide Version 2.0.3 using a call to a helper ($this->db->insert_string()) of the Database class.
foreach ($data as $row)
{
$error_code = $this->db->insert_string('units', $row);
}
Refer to http://codeigniter.com/user_guide/database/helpers.html
The insert_string function that the Database class provides appears to take an associative array, build an INSERT statement from the elements inside, execute it and then return a numerical error code.

LOL, it's not pretty, but it might work sometimes:
<input name="u_id[]" value="76">
<input name="un[]" value="1">
<input type="text" name="ue[]" value="11">
<input type="text" name="up[]" value="111">
<input name="u_id[]" value="77">
<input name="un[]" value="2">
<input type="text" name="ue[]" value="22">
<input type="text" name="up[]" value="222">
<input name="un[]" value="3">
<input type="text" name="ue[]" value="33">
<input type="text" name="up[]" value="333">
$u_id=$this->input->post('u_id');
$un=$this->input->post('un');
$up=$this->input->post('up');
$ue=$this->input->post('ue');
for($i=0;$i<count($u_id);$i++){
for($ii=0;$ii<count($un[$i]);$ii++){
(count($un[$i])>1)?$unn=$un[$i][$ii+1]:$unn=$un[$i][$ii];
(count($ue[$i])>1)?$uen=$ue[$i][$ii+1]:$uen=$ue[$i][$ii];
(count($up[$i])>1)?$upn=$up[$i][$ii+1]:$upn=$up[$i][$ii];
$this->db->insert('units', array(//use db insert here
'u_id'=>$u_id[$i][0],
'un'=>$unn,
'ue'=>$uen,
'up'=>$upn,
));
}
}
I'd go so far as to suggest you not use it. But perhaps it might inspire someone to offer a better solution.
Cheers.
