Get the last insert id

Question

Hello I am using cakePHP 1.3 and I am unable to retreive the last inserted row's id. I actually am using $this->Model->id to retreive the last inserted id but I am unable to get the id. When tried to check what is return type, it says as bool(false), which means nothing is returned.

Here I am loading a different model in a different controller, so would that be the issue?? But even though I am loading, I get back nothing!!

$this->loadModel('Contact');
$this->Contact->query("insert into contacts(tblContact_firstName,tblContact_lastName,tblContact_company,tblContact_department,tblContact_address,tblContact_country,tblContact_city,tblContact_state,tblContact_zipcode,tblContact_phone1,tblContact_email1) values('$sanitizedFormData[fname]','$sanitizedFormData[lname]','','$sanitizedFormData[company]','$sanitizedFormData[address]','$sanitizedFormData[country]','$sanitizedFormData[city]','$sanitizedFormData[state]','$sanitizedFormData[zip]','$sanitizedFormData[phone]','$sanitizedFormData[email]');");

$this->loadModel('Contact');
$contactId = $this->Contact->id;

And when I printed the $this->Contact array recursively, I found the value of "id" key empty. So that explains why I was receiving an empty value.

Now given my situation, how would I get the last inserted id, specific to the controller Contact?

Answer 1

I think you just want to do:

$this->getLastInsertID();

Answer 2

If this is MySQl you could use "SELECT from contacts LAST_INSERT_ID()" query to get last ID. or just "SELECT LAST_INSERT_ID()"

For MSSQL it is "SELECT @@IDENTITY".

This bypasses any solution in cakePHP though, so there might be a better solution.

Answer 3

When you use query() you loose a lot of automagic cakephp provides. Use save() instead.

In fact, you even do not need to load Contact in this case. You can execute any query from the current controller with query() even saving to any other table.

You can also avoid using loadModel() if your current model is somehow associated with Contact ( $this->CurrentModel->AnotherOne->Contact->save(...) ).

Answer 4

You can get last inserted record id by

echo $this->ModelName->getLastInsertID();

Alternately, you can use:

echo $this->ModelName->getInsertID();

This methods can be found in cake/libs/model/model.php on line 2775

Note: This function doesn't work if you run the insert query manually
