Hi,

New web app with CF4 new things to learn....

I create a form with db loader action and with a where statement .

I could capture the value of a column (autoindex autoincrement field in the db) as cf_id.
But I have the value of the first row in the table ("1").

I couldn't understand how to use insertid to obtain the last value of the field in the table (like mysql last_insert_id).

I have make a request in where statement as:

$lastid=$database->insertid();

then capture the data with an echo that call $lastid.

But it couldn't pass the data.

Is it possible to have some hints about the sintax that I've to use?

Thanks in advance.

Hi fede,

I'm sorry but I don't understand what you are trying to do here?

Please see this FAQ if you need to know the ID of a saved record.

I try to explain better, thanks for your answer.
I need to obtain last id of a field cf_id in a table, then use the value +1 as counter.
like http://www.chronoengine.com/forums/posts/t10525/p10525.html in CF4.

I create a form with db loader action and with a where statement .

I could capture the value of a column (autoindex autoincrement field in the db) as cf_id.
But I have the value of the first row in the table ("1").

and this is ok.

I use:

cf_id<?php echo $form->data('cf_id']:?>

the "only" sintax that return me a value.... (in the where statement of the db loader action)

I need to obtain the last value in the last record ( the last row).

solution one:
If I try to sort the data with ORDER BY i couldn't find the correct sintax.

In the help of the db loader action:

-You can order the results and so control which record will be returned, use "ORDER BY" word in the WHERE box. e. g. ORDER by 'id'

I had try to add the "Order by" that should be DESC without success.

solution two:
I had try also to count the row but I didn't find a correct sintax that returns me data.

I search in the forum but didn't find case of use a row count in the where staement in dbloader.

errata:

cf_id<?php echo $form->data('cf_id'];?>
