But when I try to POST in postman it gives me the error "Column 'AuthorID' cannot be null". AuthorID is the primary key.it give me the error "Column 'AuthorID' cannot be null" but AuthorID already has input, I just wanna change BirthPlace.
function index_post() {
$author = array(
'AuthorID' => $this->post('AuthorID'),
'AuthorName' => $this->post('AuthorName'),
'BookID' => $this->post('BookID'),
'BirthPlace' => $this->post('BirthPlace'),
'Email' => $this->post('Email'),
'Education' => $this->post('Education'),
'Phone' => $this->post('Phone'),
'Address' => $this->post('Address'),
'Nationality' => $this->post('Nationality'));
$insert = $this->db->insert('author', $author);
if ($insert) {
$result = ["took"=>$_SERVER["REQUEST_TIME_FLOAT"],
"code"=>200,
"message"=>"Add Data Success",
"author"=>$author];
$this->response($result, 200);
} else {
$result = ["took"=>$_SERVER["REQUEST_TIME_FLOAT"],
"code"=>200,
"message"=>"Failed Add Data",
"author"=>$author];
$this->response($result, 502);
}
}
when I try PUT in postman it give me success message but the data is not update. AuthorID is null, BoodID is null, i already input AuthorID, BookID in postman and still data cannot update,
function index_put() {
$id = $this->put('AuthorID');
$author = array(
'AuthorID' => $this->put('AuthorID'),
'AuthorName' => $this->put('AuthorName'),
'BookID' => $this->put('BookID'),
'BirthPlace' => $this->put('BirthPlace'),
'Email' => $this->put('Email'),
'Education' => $this->put('Education'),
'Phone' => $this->put('Phone'),
'Address' => $this->put('Address'),
'Nationality' => $this->put('Nationality'));
$this->db->where('AuthorID', $id);
$update = $this->db->update('author', $author);
if ($update) {
$result = ["took"=>$_SERVER["REQUEST_TIME_FLOAT"],
"code"=>200,
"message"=>"Data Update Success",
"author"=>$author];
$this->response($result, 200);
} else {
$result = ["took"=>$_SERVER["REQUEST_TIME_FLOAT"],
"code"=>200,
"message"=>"Failed Update Data",
"author"=>$author];
$this->response($result, 502);
}
}
result index_put
{
"took": 1637045848.425828,
"code": 200,
"message": "Data Update Success",
"author": {
"AuthorID": null,
"AuthorName": "Jack Dane",
"BookID": null,
"BirthPlace": "Jakarta",
"Email": "Jackdane#gmail.com",
"Education": "Bachelor At Univercity Of Canada",
"Phone": "09199191",
"Address": "4457 Grey Fox Farm Road, Houston, Texas",
"Nationality": "America"
}
}
and when I try DELETE it gives me "status": "Success Delete Data" but the data is not removed when I check in PHPMyAdmin.
function index_delete() {
$id = $this->delete('AuthorID');
$this->db->where('AuthorID', $id);
$delete = $this->db->delete('author');
if ($delete) {
$this->response(array('status' => 'Success Delete Data'), 200);
}
else{
$this->response(array('status' => 'fail Delete Data', 502));
}
}
