从父表插入外键值到子表

Question

我有两个表贷款（父表）和收据（子表）我想要做的是当一行被插入父表（贷款）我想要外国键（app_file_id）也于子表

$values = $_POST; 
foreach ($values as &$value) { 
    $value = mysql_real_escape_string($value); 
} 

$sql1="INSERT INTO loan (loan_id,officer_department,app_file_id) 
VALUES ('','$values[officer_department]','$values[app_file_id]')"; 

$result = mysql_query($sql1); 
if (!$result) { 
    die('Invalid query: ' . mysql_error()); 
} 

我设法父表，但子表（回执）插入数据插入和外键（app_file_id），我如何得到它还要插入收据表中

Answer 1

试试这个

$sql1="INSERT INTO loan (loan_id,officer_department,app_file_id) 
VALUES ('','$values[officer_department]','$values[app_file_id]')"; 

$result = mysql_query($sql1); 

if (!$result) { 
      die('Invalid query: ' . mysql_error()); 
} 

@mysql_query("INSERT INTO receipt (app_file_id) VALUES ('{$values['app_file_id']}')");
