Insert array using codeigniter - arrays

Question

I try to insert multiple arrays into database using codeigniter and ajax. After click the submit, database insert to mysql but all the value is blank. What did I miss?
My view:
<input type="hidden" name="iduser[]" id="iduser[]" value="<?php echo $rowmyuser->iduser; ?>"/>
<input type="hidden" name="idproduk[]" id="idproduk[]" value="<?php echo $rowproduk->idproduct; ?>"/>
<input type="text" class="form-control input-sm" name="settarget[]" id="settarget[]"/>
Save
My controller:
public function inserttarget()
{
$this->target_m->inserttarget_m();
}
My model:
function inserttarget_m() {
$iduser = $this->input->post("iduser");
$idproduk = $this->input->post("idproduk");
$settarget = $this->input->post("settarget");
$temp = count($this->input->post("iduser"));
$datatarget = array();
for($i=0; $i < 3; $i++)
{
$datatarget[]=array(
"iduser"=>$iduser[$i],
"idproduct"=>$idproduk[$i],
"target"=>$settarget[$i],
);
}
$this->db->insert_batch("tbl_targetsales",$datatarget);
}
The Ajax code:
function insert_target()
{
var DataString=$("#frm_target").serialize();
document.getElementById("save_target").innerHTML = "<i class='fa fa-cog fa-spin fa-lg fa-fw'></i> Saving...";
$.ajax({
type: 'POST',
url: '<?php echo base_url();?>target/inserttarget',
data: DataString,
success: function (data) {
//jQuery("#attendence_report_holder").html(response);
swal({
text: 'success'
});
$("#frm_target")[0].reset();
document.getElementById("save_target").innerHTML = "<i class='fa fa-save'> </i>Save";
window.location='<?php echo base_url(); ?>target';
},
error:function(data){
swal({
text: 'error',
});
document.getElementById("save_target").innerHTML = "<i class='fa fa-save'> </i>Save";
}
});
}
I need advice please, what is the problem in the code. Thanks in advance

Answer 1

first you call wrong the inputs in your html for the inputs name are
iduser[]
idproduk[]
settarget[]
and in your model you call with, and in the array you make to insert you call different variables that you save it
iduser
idproduct
target
replace all you madel with (using the correct names from form and variables names)
function inserttarget_m() {
$iduser = $this->input->post("iduser");
$idproduct = $this->input->post("idproduk");
$target = $this->input->post("settarget");
$temp = count($iduser);
$datatarget = array();
for($i=0; $i < $temp; $i++){
$datatarget[] = array(
"iduser" => $iduser[$i],
"idproduct" => $idproduct[$i],
"target" => $target[$i],
);
}
$this->db->insert_batch("tbl_targetsales", $datatarget);
}
