get unique id

get unique id

Is it possible to get the unique ID of the record and insert it into mkdir() command to create a sub folder that is the new ID of the account, before the new record is created?

for example

New record is created and the photo is uploaded to the directory/sub folder that is named the same as the ID auto generated. All done with the same insert record funtion on the same page

Assuming that there is only one person ever going to be entering records at a time a quick and dirty solution would be to have a recordset that returns the last id in the table and then add 1 to it.

Pseudo code would look like:

mysql_select_db($database_connDB, $connDB);

$query_rsGetLastID = "SELECT id FROM table ORDER BY id DESC LIMIT 1";
$rsGetLastID = mysql_query($query_rsGetLastID, $connDB) or die(mysql_error());
$row_rsGetLastID = mysql_fetch_assoc($rsGetLastID);
$totalRows_rsGetLastID = mysql_num_rows($rsGetLastID);

$nextID = $row_rsSortOrder['sortorder']+1;

Then use $nextID in your code to create directories etc. before doing the upload and insert.

If there is more than one person entering data then you would need a more robust solution.

this doesn't work, as it is a web based program for multiple users. everything i have read says that can cause problems. it is not important, i have worked around it, but i was just curious.
