需要有关使用PDO在PHP中更新表单的帮助

Question

All columns are in TEXT format apart from the BDid column which is in int. 除int的BDid列外，所有列均采用TEXT格式。 Ive had the code running smoothly with un-preared statements but thought I would update it, with the same data in and the same table. Ive的代码使用未声明的语句可以平稳运行，但我想我将使用相同的数据和相同的表对其进行更新。

No errors are returned, but no rows are affected. 不返回任何错误，但不影响任何行。

The code is not getting any error but the MySQL is not updating 代码没有收到任何错误，但是MySQL没有更新

Answer 1

it looks like you need to change the execute line to this: 看来您需要将执行行更改为此：

$q->execute(array($first_name, $sur_name, $company, $location, $supervisor, $department,$job_description, $hire_date, $email, $message, $id)); $ q-> execute（array（$ first_name，$ sur_name，$ company，$ location，$ supervisor，$ department，$ job_description，$ hire_date，$ email，$ message，$ id））;
