}
// create array variable to store category data
$category_data = array();
$sql_query = "SELECT Category_ID, Category_name
FROM tbl_category
ORDER BY Category_ID ASC";
$stmt_category = $connect->stmt_init();
if ($stmt_category->prepare($sql_query)) {
// Execute query
$stmt_category->execute();
// store result
$stmt_category->store_result();
$stmt_category->bind_result($category_data['Category_ID'],
$category_data['Category_name']
);
}
$sql_query = "SELECT Menu_image FROM tbl_jadwal WHERE Menu_ID = ?";
$stmt = $connect->stmt_init();
if ($stmt->prepare($sql_query)) {
// Bind your variables to replace the ?s

updating all data except image file
$sql_query = "UPDATE tbl_jadwal

$update_result = $stmt->store_result();
$stmt->close();
}
}
check update result
if ($update_result) {
$error['update_data'] = " <span class='label label-primary'>Success update</span>";
} else {
$error['update_data'] = " <span class='label label-danger'>failed update</span>";
}
This my database structure

Answer 1

replace bind_param() with bindParam(':data', $data);
or try $stmt->execute(array(':data' => $data))

Answer 2

Hi Just write the simple query firstly and add EXPLAIN before it.
For example:
EXPLAIN update table set name='test' where id=1;
This statement will show all the possible error. In this way you will be able to resolve the problem.
