ItemID out of Sync

ItemID out of Sync

Hi,

I am using DA and UE to insert a record into a MySQL DB.

I am using UE to upload an image with the insert form.

The image uploads and the DB updates fine.

My problem is... I am using the ItemID to rename the uploaded image. (WADA_Insert_items).

This is not working as I would expect.
1) If I launch a new browser session and preform an insert, I get a file name of '.jpg'
2) On a secondary attempt, in the same session, I get a file name of (e.x. '99.jpg'). This is exactly one count of the actual ItemID of 100.

How can I correct this so that it work for the start of a new session and names the files accordingly.

The following is a SQL and session DUMP from the Detal page following an insert.

SQL: SELECT VisitorID, VisitorGroupID, CompanyID, ItemID, ItemCatID, ItemName, ItemShortDesc, ItemLongDesc, helixNumber, CustomerPartNumber, PONumber, OrderQTY, QTYProduced, release1, QTYOnHand FROM items WHERE ItemID = -1 OR ( -1= -1 AND ItemID= 100)

array(17) {
["WAENCRYPTEDRETURNUSED"]=>
bool(false)
["WAENCRYPTEDRETURNSUCCESS"]=>
bool(false)
["SecurityAssist_VisitorID"]=>
string(1) "1"
["VisitorGroupID"]=>
string(1) "3"
["VisitorEmail"]=>
string(28) "support@heliximpressions.com"
["VisitorBillName"]=>
string(22) "Helix Impressions Inc."
["VisitorID"]=>

["userID"]=>
string(5) "helix"
["UserName"]=>
string(5) "helix"
["CompanyID"]=>
string(1) "1"
["CompanyName"]=>
string(22) "Helix Impressions Inc."
["GroupName"]=>
string(20) "Helix Administrators"
["showContent"]=>
int(1)
["editContent"]=>
int(1)
["WADA_OrderClause_index"]=>
string(0) ""
["Insert_ImageName"]=>
string(12) "99_thumb.jpg"
["WADA_Insert_items"]=>
int(100)
}

ItemID out of Sync - solved?

I think I figured this one out.

The ItemID's were out of sync because there is no way - that I can find - to get the next MySQL, auto-increment id without inserting a record first. So I was unable to generate the proper file name to be inserted into the record before the actual record insert.

The solution was kind of simple. In a nut shell I...
1. saved my update.php as insert.php
2. modified new insert.php to execute a INSERT query, before page load, to create a blank row. (I just gave one of the numeric fields a zero value)
3. grabbed the 'mysql_insert_id();' value and used it to generate an UPDATE query.

Granted, it's not perfect. If the user changes their mind after loading the insert.php, it will leave a blank record behind. I've got to figure that one out.

If anyone has a better way or any suggestions, please let me know.

Cheers
Doug

using the database ID as the file name is not going to be very practical.

to upload an image, and store it's in a database, the order of operations is:
File Upload
Database Insert.

The ID of the inserted record cannot be known until the record has been inserted.

because the upload happens before the insert, using the ID is not going to work very well.

Thanks Jason,

The method of turning the INSERT into an UPDATE seems to achieve my goal.

The blank insert generates the ID and I can use that value to perform an UPDATE that can now use that ID for an Image File name.

The reason I am stuck with using the record ID is: the form has very few data constraints, so there are no other usable vales at the form level. Also, the native naming convention of my client's files could be very long and contain spaces and other nasty things.

So, the record ID seemed to me to be the only reliable choice.

If I can't figure out an intelligent solution to the abandoned records issue, that I may have to just use the native file name and standard insert.

Cheers
Doug
