Codeigniter phpexcel validation array before import - php

Question

i want to import excel as json data in Codeigniter with validation for each row.
excel column
|A |B |C
|demo|DM1|11231
|demo|DM2|87128
...
my code for get array from excel
//start loop excel from 2nd row. Row 1 is title row
for ($j=2; $j < $lastRow; $j++ ){
$myArray[] = array(
'site_id' => $objWorksheet->getCell('B'.$j)->getValue(),
'site_name' => $objWorksheet->getCell('A'.$j)->getValue(),
'id_site_doc'=> $objWorksheet->getCell('C'.$j)->getValue()
}
//validate the array
$this->form_validation->set_data($myArray);
$this->form_validation->reset_validation();
foreach ($myArray as $key => $value) {
$columnB = $myArray[$key]['site_id'];
$columnA = $myArray[$key]['site_name'];
$columnC = $myArray[$key]['id_site_doc'];
}
if (empty($columnB )){
$this->form_validation->set_rules('mr_submit_target', 'site_id on row ' . $j, 'required');
}
else if (empty($columnA )){
$this->form_validation->set_rules('short_desc', 'site_name on row ' . $j, 'required');
}
else if (empty($columnC )) {
$this->form_validation->set_rules('cd_id', 'id_site_doc on row ' . $j, 'required');
}
if ($this->form_validation->run() == FALSE){
$errorArray[$j]=$this->form_validation->error_array();
print_r($errorArray[$j]);
}else{
//post to endpoint
$data_to_post = json_encode($myArray);
$curl = curl_init('http://myendpoint/implementation_bom_op');
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($curl, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Content-Length: ' . strlen($data_to_post))
);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, $data_to_post);
// Send the request
$result = curl_exec($curl);
echo $result;
}
}
my expectation
the data will be post only if have full validation, when there are blank cell in one of each cell it will throw error. is that possible? or it should be on endpoint side?

//start loop excel from 2nd row. Row 1 is title row
for ($j=2; $j < $lastRow; $j++ ){
$columnB = $objWorksheet->getCell('B'.$j)->getValue();
$columnA = $objWorksheet->getCell('A'.$j)->getValue();
$columnC = $objWorksheet->getCell('C'.$j)->getValue();
//validate the array
$error = 0;
if($columnB == ""){
$errorArray[$j][] = 'your-error-here';
$error +=1;
}
if($columnA == ""){
$errorArray[$j][] = 'your-error-here';
$error +=1;
}
if($columnC == ""){
$errorArray[$j][] = 'your-error-here';
$error +=1;
}
if($error != 0){
continue; //do something with the error
}else{
$myArray['site_id'] = $columnB;
$myArray['site_name'] = $columnA;
$myArray['id_site_doc'] = $columnC;
}
}
//post to endpoint
$data_to_post = json_encode($myArray);
$curl = curl_init('http://myendpoint/implementation_bom_op');
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($curl, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Content-Length: ' . strlen($data_to_post))
);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, $data_to_post);
// Send the request
$result = curl_exec($curl);
echo $result;
This should work for you.
