Closed 5 years ago.
I have a form that submitted a stringified JSON array. This is the data example:
"[{'name':'i_cp_nm','value':'1'},{'name':'i_cp_tp','value':'2'},{'name':'i_cp_mb','value':'3'},{'name':'i_cp_em','value':'4'},{'name':'i_cp_jb','value':'5'},{'name':'i_cp_nt','value':'6'},{'name':'i_cp_nm','value':'7'},{'name':'i_cp_tp','value':'8'},{'name':'i_cp_mb','value':'9'},{'name':'i_cp_em','value':'10'},{'name':'i_cp_jb','value':'11'},{'name':'i_cp_nt','value':'12'}]";
This is the desired inserted data looks like:
i_cp_jd i_cp_nm i_cp_tp i_cp_mb i_cp_em i_cp_jb i_cp_nt
xxx 1 2 3 4 5 6
xxx 7 8 9 10 11 12
This is the current loop, but I do not know if this is right:
$arr_cp = //arr_data
foreach($arr_cp as $val_cp){
$dt_cp['i_cp_jd'] = $this->input->post('i_v_id');
//didn't know what to do here
$this->model_vendor->insert_vendor_pic($dt_cp);
}
the the insert method:
function insert_vendor_pic($dt_cp){
$query = $this->db->insert('vendordetail_pic',$dt_cp);
return $query;
}

Answer 1

All you have to do is using json_decode:
$arr_cp = json_decode($yourJsonData, true);

Answer 2

Try this function for prepare/convert your input to matrix:
function prepareData($rawData) {
$rawData = str_replace("'", '"', $rawData);
$data = array();
foreach(json_decode($rawData, true) as $d) {
if (!isset($data[$d['name']])) {
$data[$d['name']] = array();
}
$data[$d['name']][] = $d['value'];
}
$rows = array();
foreach ($data as $col => $values) {
foreach ($values as $i => $v) {
if (!isset($rows[$i])) {
$rows[$i] = array();
}
$rows[$i][$col] = $v;
}
}
return $rows;
}
Convert:
$rawData = "[{'name':'i_cp_nm','value':'1'},{'name':'i_cp_tp','value':'2'},{'name':'i_cp_mb','value':'3'},{'name':'i_cp_em','value':'4'},{'name':'i_cp_jb','value':'5'},{'name':'i_cp_nt','value':'6'},{'name':'i_cp_nm','value':'7'},{'name':'i_cp_tp','value':'8'},{'name':'i_cp_mb','value':'9'},{'name':'i_cp_em','value':'10'},{'name':'i_cp_jb','value':'11'},{'name':'i_cp_nt','value':'12'}]";
print_r(prepareData($rawData));
Output:
Array
(
[0] => Array
(
[i_cp_nm] => 1
[i_cp_tp] => 2
[i_cp_mb] => 3
[i_cp_em] => 4
[i_cp_jb] => 5
[i_cp_nt] => 6
)
[1] => Array
(
[i_cp_nm] => 7
[i_cp_tp] => 8
[i_cp_mb] => 9
[i_cp_em] => 10
[i_cp_jb] => 11
[i_cp_nt] => 12
)
)
Finally you can simple insert this data to DB any way you like.

Answer 3

If you want to do it systematically then you should use an appropriate JSON parser/ deserializer to create an instance of the domain or whatever you are supposed to create from that form data and insert those instances in the DB.

Answer 5

The data in the json format, so you have to decode json into array by using
$arr_cp = json_decode($arr_cp, TRUE);
then do $arr_cp into foreach loop
foreach($arr_cp as $val_cp){
$dt_cp['i_cp_jd'] = $this->input->post('i_v_id');
//didn't know what to do here
$this->model_vendor->insert_vendor_pic($dt_cp);
}
