Fillable PDF form needs to be non fillable upon submit email

helpfull . thank you

You should set the form to submit to a server-side script such as ASP.net or PHP. Sending using a server-side script eliminates the need for client-side email software such as OUTLOOK or Web Mail. If you can utilize ASP.net, then iTextSharp is available for the script to "flatten" the form fields.

Alternately: You can continue to send the submission using each end-users MAPI client side email software; and, loop through each field using Adobe's JavaScript and set the properties to read-only before the form is submitted. This process is reversible, less secure, and less reliable than using an ASP.net script.

Visit the following website for online ASP.net examples:

If you are the one who is emailing it, add security to restrict changes. Or Flatten the fields. Or export to jpeg.

Tell us more about your process.

In what application is this form going to be used?
