Project description
The task is to save the forms that are sent with many files in the admin.
For this purpose, AjaxUpload is used in conjunction with FormIt. But AjaxUpload was a bug, which the developer of this add-on also confirmed.
The bug is that when you send a form with many files, one or more of them eventually disappear.
I mean. Incomplete number of files comes to the post office and incomplete number is saved in the admin.
The developer wrote that something was wrong with the session filling.
You need to solve the problem so that all attached files are saved along with the form in the admin and go to the post office, as intended.
To do this, you can either correct the addition or suggest another working option.
Access to the admin skin after the choice of the performer.
The contractor must be familiar with the MODX API and the FormIt add-on.
Payment will be made only upon the fact of the work performed.
Term 3-4 days.
