can someone please tell me how to modify this code so that instead of it it adding a new field to the observation table i would like it to update the table instead where the username is equal to :user and the child_ID is equal to :child_id
<?php
//load and connect to MySQL database stuff
require("config.inc.php");
if (!empty($_POST)) {
//initial query
$query = "INSERT INTO observation ( username, elg1, elg2, elg3, elg4, elg5,elg6, elg7, elg8, elg9, elg10, elg11, elg12, elg13, elg14, elg15, elg16, elg17, col1, col2, col3, child_id ) VALUES ( :user, :elg1, :elg2, :elg3, :elg4, :elg5, :elg6, :elg7, :elg8, :elg9, :elg10, :elg11, :elg12, :elg13, :elg14, :elg15, :elg16, :elg17, :col1, :col2, :col3, :child_id )";
//Update query
$query_params = array(
':user' => $_POST['username'],
':elg1' => $_POST['elg1'],
':elg2' => $_POST['elg2'],
':elg3' => $_POST['elg3'],
':elg4' => $_POST['elg4'],
':elg5' => $_POST['elg5'],
':elg6' => $_POST['elg6'],
':elg7' => $_POST['elg7'],
':elg8' => $_POST['elg8'],
':elg9' => $_POST['elg9'],
':elg10' => $_POST['elg10'],
':elg11' => $_POST['elg11'],
':elg12' => $_POST['elg12'],
':elg13' => $_POST['elg13'],
':elg14' => $_POST['elg14'],
':elg15' => $_POST['elg15'],
':elg16' => $_POST['elg16'],
':elg17' => $_POST['elg17'],
':col1' => $_POST['col1'],
':col2' => $_POST['col2'],
':col3' => $_POST['col3'],
':child_id' => $_POST['child_id']
);
//execute query
try {
$stmt = $db->prepare($query);
$result = $stmt->execute($query_params);
}
catch (PDOException $ex) {
// For testing, you could use a die and message.
//die("Failed to run query: " . $ex->getMessage());
//or just use this use this one:
$response["success"] = 0;
$response["message"] = "Database Error. Couldn't add post!" . $ex->getMessage();
die(json_encode($response));
}
$response["success"] = 1;
$response["message"] = "Post Successfully Added!";
echo json_encode($response);
} else {
