Basically i want to insert a Foreign key acc_id in patient_info table from account_info table.
I have managed to retrieve the data from my database. Now I want to insert it in another table as Foreign key. I have following code :
try {
$stmt = $pdo->query('SELECT acc_id FROM account_info ORDER BY acc_id DESC LIMIT 1');
while($row = $stmt->fetch(PDO::FETCH_OBJ))
{
// Assign each row of data to associative array
$data[] = $row;
}
// Return data as JSON
echo json_encode($data);
}
How can I insert the value in the table?
this is the full code :
<?php
header('Access-Control-Allow-Origin: *');
// Define database connection parameters
$hn = 'localhost';
$un = 'root';
$pwd = '';
$db = 'ringabell';
$cs = 'utf8';
// Set up the PDO parameters
$dsn = "mysql:host=" . $hn . ";port=3306;dbname=" . $db . ";charset=" . $cs;
$opt = array(
PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,
PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_OBJ,
PDO::ATTR_EMULATE_PREPARES => false,
);
// Create a PDO instance (connect to the database)
$pdo = new PDO($dsn, $un, $pwd, $opt);
// Retrieve specific parameter from supplied URL
$key = strip_tags($_REQUEST['key']);
$data = array();
switch($key)
{
// Add a new record to the technologies table
case "create":
// Sanitise URL supplied value
$acc_id = filter_var($_REQUEST['acc_id'],
FILTER_SANITIZE_STRING, FILTER_FLAG_ENCODE_LOW);
$p_fname = filter_var($_REQUEST['p_fname'],
FILTER_SANITIZE_STRING, FILTER_FLAG_ENCODE_LOW);
$p_lname = filter_var($_REQUEST['p_lname'],
FILTER_SANITIZE_STRING, FILTER_FLAG_ENCODE_LOW);
$p_gender = filter_var($_REQUEST['p_gender'],
FILTER_SANITIZE_STRING, FILTER_FLAG_ENCODE_LOW);
$p_condition = filter_var($_REQUEST['p_condition'],
FILTER_SANITIZE_STRING, FILTER_FLAG_ENCODE_LOW);
$p_emergencycontact = filter_var($_REQUEST['p_emergencycontact'],
FILTER_SANITIZE_STRING, FILTER_FLAG_ENCODE_LOW);
$p_birthdate = filter_var($_REQUEST['p_birthdate'],
FILTER_SANITIZE_STRING, FILTER_FLAG_ENCODE_LOW);
try{
$stmt = $pdo->query('SELECT acc_id FROM account_info ORDER BY acc_id DESC LIMIT 1');
while($row = $stmt->fetch(PDO::FETCH_OBJ))
{
// Assign each row of data to associative array
$data[] = $row;
}
// Return data as JSON
echo json_encode($data);
$sql= "INSERT INTO patient_info(acc_id, p_fname, p_lname, p_gender, p_condition, p_birthdate, p_emergencycontact)
VALUES(:acc_id, :p_fname, :p_lname, :p_gender, :p_condition, :p_birthdate, :p_emergencycontact)";
$stmt = $pdo->prepare($sql);
$stmt->bindParam(':p_fname', $p_fname, PDO::PARAM_STR);
$stmt->bindParam(':p_lname', $p_lname, PDO::PARAM_STR);
$stmt->bindParam(':p_gender', $p_gender, PDO::PARAM_STR);
$stmt->bindParam(':p_condition', $p_condition, PDO::PARAM_STR);
$stmt->bindParam(':p_birthdate', $p_birthdate, PDO::PARAM_STR);
$stmt->bindParam(':p_emergencycontact', $p_emergencycontact, PDO::PARAM_STR);
$stmt->bindParam(':acc_id', $acc_id, PDO::PARAM_STR);
$stmt->execute();
echo json_encode(array('message' => 'Congratulations the record was added to the database'));
}
// Catch any errors in running the prepared statement
catch(PDOException $e)
{
echo $e->getMessage();
}
break;
}
?>
I am getting this error:
ERROR SyntaxError: Unexpected token < in JSON at position 0
at JSON.parse (<anonymous>)
I am getting the error here which links back to the php file:
load()
{
this.http.get('http://localhost:10080/ionic/patients.php')
.map(res => res.json())
.subscribe(data =>
{
this.items = data;
});
}
