insert batch data array?

问题:

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?

回答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.
