NULL Value inserted in Database (Codeigniter) - php

Question

I Am trying to insert data in DB,But somehow NULL is inserted in DB
Here Is My Controller
foreach($this->input->post('resume_id') as $key =>$value ){
$ResumeInsert[$key]['resume_keyid'] = $Resume['resume_id'][$key];
$ResumeInsert[$key]['employer_name'] = $Resume['employer_name'][$key];
$ResumeInsert[$key]['start_Date'] = $Resume['start_Date'][$key];
$ResumeInsert[$key]['end_date'] = $Resume['end_date'][$key];
$ResumeInsert[$key]['type_id'] = $Resume['type_id'][$key];
$ResumeInsert[$key]['position'] = $Resume['position'][$key];
$ResumeInsert[$key]['responsibility'] = $Resume['responsibility'][$key];
$ResumeInsert[$key]['Skills'] = $Resume['Skills'][$key];
if(isset($Resume['id'][$key]) ){
$Key_Resume__ExistIDs[]=$Resume['id'][$key];
$ResumeUpdate[$key]=$ResumeInsert[$key];
$ResumeUpdate[$key]['resume_id']=$Resume['id'][$key];
unset($ResumeInsert[$key]);
}
else{
$ResumeInsert[$key]['resume_id'] = $GetLastID;
print_r ($ResumeInsert[$key]);exit;
$GetLastID++;
}
}
$idsToDelete='';
if(empty($ResumeInsert) && empty($ResumeUpdate)){
$idsToDelete=array_diff($Key_Resume_IDs,$Key_Resume__ExistIDs);
}
$status=$this->Resume_model->ProcessData($idsToDelete,$ResumeUpdate,$user_id,$ResumeInsert,$imgInsert,$imgUpdate);
redirect('Resume','refresh');
Here Is My Code Of Model
function ProcessData($idsToDelete,$tbl_resumeUpdate,$user_id,$tbl_resumeInsert,$imgInsert,$imgUpdate){
$this->db->trans_start();
if(!empty($idsToDelete)){
$this->delete_tbl_resume($idsToDelete);
}
if(!empty($tbl_resumeUpdate)){
//echo "up";exit;
$this->update_tbl_resume($tbl_resumeUpdate);
}
if(!empty($tbl_resumeInsert)){
//echo "int";exit;
$this->insert_tbl_resume($user_id,$tbl_resumeInsert);
}
if(!empty($imgInsert)){
$this->insert_tbl_file_paths($imgInsert);
}
if(!empty($imgUpdate)){
$this->update_tbl_file_paths($imgUpdate);
}
return $this->db->trans_complete();
}
This is Insert Query
function insert_tbl_resume($id,$arrtbl_resume){
$this->db->insert_batch('tbl_resume', $arrtbl_resume);
}
In Above Code,Null Value inserted In DB.
when i Print above query,it displays blank
Any Help Please?

You should use form_validation library. I'm giving you an example, you can edit and use it.
In autoload.php, edit $autoload['libraries'] = array(); line to:
$autoload['libraries'] = array('form_validation');
Then, use form_validation in your controller file. For example:
$this->form_validation->set_rules('resume_keyid', 'Resume ID', 'required');
if ($this->form_validation->run() == FALSE)
{
$this->index() // if there is an error, user will redirect to this function
}
else
{
$this->Resume_model->ProcessData();
}
Also please use $this->input->post('resume_keyid', TRUE); structure in your model. "TRUE" means "open XSS filter". Because in CI 3, it comes off as default. If you don't want it, just remove. If you use CI 2, you don't need to add "TRUE".
A few suggestions:
1 - Don't use camelization when you name functions. For example; use process_data() instead of processData()
2 - Check CI Form Validation Document for all details (E.g. all references)
3 - I think you can use $this->db->insert();, just create an array and POST it. If you make it, you'll understand what's wrong.
