如何从插入的数据中获取最后一个ID？

Question

I have an option to send multiple rows into an table, i'm using an foreach to do that:

if (is_array($add['jobname'])) {
$insert = "INSERT INTO job_offers (job_category, status) VALUES ";

foreach ($add['job_name'] as $key => $value) {

$insertedval[] = "
('" . safe($add['job_category'][$key]) . "', 
 '" . safe($add['status'][$key]) . "')";

}
}
$insert .= implode($insertedval, ",");

$last_id = db_query($insert, '+id?'); //gets the last generated ID, its a function that i created, and working great.

The problem is that i want to get the last ID, and i'm getting, but i'm inserting multiple rows into the database, and i want to get the ID's from all the inserted values, because they are being sent at the same time.

I can't put the $last_id variable inside the foreach loop, what do i do?

ps: i'm using auto increment

Answer 1

Can you try something like this?

$db = new PDO("mssql:host=$host;dbname=$dbname, $user, $pass");
$db->beginTransaction();
$stmt = $db->prepare('INSERT INTO job_offers (job_category, status) VALUES (?, ?)');

$insertedIds = array();
foreach ($add['job_name'] as $key => $value) {
    $stmt->execute($add['job_category'][$key], $add['status'][$key]));
    $id = $db->lastInsertId();
    array_push($insertedIds, $id);
}

$db->commit();

the ids should be in the insertedIds.

Answer 2

You can't.

Only by saving the the last index id before the inserted data, and than do it again after and select all the ids between that range.

SELECT ID FROM job_offers ID BETWEEN last-before-insert AND last-after-insert

Answer 3

You don't need a custom function to get the last insert id , there is already one built into both php mysqli and php PDO extensions .

As far I know , the last insert id is session aware , meaning you will get the last insert from the current insert requests only .

Get last inset id using PHP PDO

$pdo->lastInsertId();

Get last insert id using mysqli

$mysqli->insert_id;

$pdo and $mysqli are the connection variables
