php mysqli_insert_id（）错误

Question

I am trying to get the last inserted query's id.. after some searching i found the

<?php mysqli_insert_id($getCarInfo); ?>

command, but i could not get it to work.

I am new to php and am using DreamWeaver CS6, this is the connection code that the dreamweaver created:

<?php
# FileName="Connection_php_mysql.htm"
# Type="MYSQL"
# HTTP="true"
$hostname_getCarInfo = "localhost";
$database_getCarInfo = "cars";
$username_getCarInfo = "root";
$password_getCarInfo = "*******";
$getCarInfo = mysql_pconnect($hostname_getCarInfo, $username_getCarInfo, $password_getCarInfo) or trigger_error(mysql_error(),E_USER_ERROR); 
?>

i heard that there are different APIs and i seen that the connection is mysql_pconnect() and i am using mysqli_..();, i do not know how to handle those nor if that is the problem.

This is the generated error:

Warning: mysqli_insert_id() expects parameter 1 to be mysqli, resource given in H:\AppServ\www\cars\insertData.php on line 170
New Record has id 0.

This is line 170:

<?php printf ("New Record has id %d.
", mysqli_insert_id($getCarInfo)); ?>

the data gets inserted successfully with no errors.. but i cannot get the ID back and that is very important for the registration to continue.

also, should i start a session? i need the ID to be paresed to another page so i can ask for the images to upload them and associate them to the ID.. or how is it done exactly?

EDIT---

Full code:

getCarInfo.php:

    <?php
# FileName="Connection_php_mysql.htm"
# Type="MYSQL"
# HTTP="true"
$hostname_getCarInfo = "localhost";
$database_getCarInfo = "cars";
$username_getCarInfo = "root";
$password_getCarInfo = "****";
$getCarInfo = mysql_pconnect($hostname_getCarInfo, $username_getCarInfo, $password_getCarInfo) or trigger_error(mysql_error(),E_USER_ERROR); 
?>

insertData.php:

Answer 1

Try looking at the example supplied by PHP.net:

<?php
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");

/* check connection */
if (mysqli_connect_errno()) {
    printf("Connect failed: %s
", mysqli_connect_error());
    exit();
}

$mysqli->query("CREATE TABLE myCity LIKE City");

$query = "INSERT INTO myCity VALUES (NULL, 'Stuttgart', 'DEU', 'Stuttgart', 617000)";
$mysqli->query($query);

printf ("New Record has id %d.
", $mysqli->insert_id);

/* drop table */
$mysqli->query("DROP TABLE myCity");

/* close connection */
$mysqli->close();
?>
