working with dynamic multiple uploads

working with dynamic multiple (repeated) uploads

Ok, will start from the beginning.

I have Security Assist set up, one of the questions it asks is how many children you have, this is stored.

I then have an update page where users can update their details, this works.

On the same page I have another form that loops another form based on how many children they have. For each loop the user can fill in the name, birthdays and a photo. This is stored in another table using the UserID from the Security Assist registration.

This works (eventually, WA does screw up more than my liking and gives no errors)

But i only got it working for a test stage. When i try to apply the DFP behaviour on the file field, no data is added into the database and no images are uploaded.

Does it not work this way? But even if the file upload didn't work, why does it then not insert any data?

Looking at the code it seems the file upload is only set to run once, and not loop.

Is this possible?

Next experiment will be to loop the upload function after the form is submitted.

If you have multiple file fields then you will need to have separate Digital File Pro Upload Server Behavior, you can try looping the Upload function, but you will need to make sure that the fileField are generated dynamically as well.

After many hours of fiddling and testing, rebuilding the form, testing again. It works!!

Set up your form, be sure to include the name and id of the form. I didn't see this highlighted anywhere but it doesn't work without it.

Apply the DA Repeater to the input fields including the file field. But not the submit button.

I used a INT from a getRecordset to set the amount of repeats. In this example it was the user's number of children.

I then used the DA Insert Multiples behaviour (all this is well document in the dataassist/ recipes)

Test to make sure all is working (the file name will be blank at the moment)

Next apply a DFP upload (from the insert menu) to the page and select the repeating elements you require. Including the file field, but make sure for the Value for the File you press the lightening bolt and find the WA_UPLOAD variables and use Server Filename, this will be sure to insert the filename as it was used and potentially changed by DFP.

(note, once you start changing things here the behaviours will disappear from your interface, meaning that you can't use the DA wizards and forms to make changes)

Find the code that uploads the file.

WA_DFP_UploadFiles("WA_UploadResult1", "fileField_".$RepeatSelectionCounter_1 ."", "2", "[NewFileName]_[Increment]", "false", $WA_UploadResult1_Params);

cut and paste the IF part into a new file leaving


Next find:
// WA DataAssist Multiple Inserts

and in the WHILE - IF curly brackets paste the contents of the previous IF you pulled earlier:

(I have put a blank between WA code and my new pasted line as I can't see any formatting options for this post)

if ($WA_insertIfNotBlank == "" || WA_AB_checkLoopedFieldsNotBlank(array($WA_insertIfNotBlank), $WA_multipleInsertCounter)) {

WA_DFP_UploadFiles("WA_UploadResult1", "fileField_".$WA_multipleInsertCounter ."", "2", "[NewFileName]_[Increment]", "false", $WA_UploadResult1_Params);

$WA_fieldValuesStr = "".$WA_DFP_UploadStatus["WA_UploadResult1"]["serverFileName"] . "|" . "".WA_AB_getLoopedFieldValue("kidName", $WA_multipleInsertCounter) ."" . "|" . "".WA_AB_getLoopedFieldValue("kidDate", $WA_multipleInsertCounter) ."";
$WA_fieldValues = explode("|", $WA_fieldValuesStr);

You will see I have replaced $RepeatSelectionCounter_1 with the repeating number for the multiple inserts loop $WA_multipleInsertCounter

And that pretty much should be it.

Good luck, is very handy if you have a table of images and and want to assign many images to an entry in another table e.g. users and users photos.
