Question

Is it possible to save image previews using custom HTML Fields?

Forms

Hey Gang,

I'm using Forms as a content generation method. Customer needs image previews on the finalized form for reviews/approvals.

I'm using a custom HTML function (here's a link to a JSFiddle http://jsfiddle.net/Xotic750/AjtLx/) to provide a pretty decent image preview solution. This solution works well, however- upon submission the image previews are completely gone. When the customer submits the form, I'd like to be able to see the previewed image flattened on the form- which it is not doing currently. Is there a way to do this or should I focus my efforts more on the base upload method? Is there something I'm missing?

Thanks,

Check out this post. Basically, you need to store the HTML encoded version of the image in a single line field, not custom HTML. Then, when the form loads, you check to see if the single line field has a value, and if it does, you decode it back into an image and place that custom HTML.

Hi,

I hope to see an answer as well. I have thought about this functionality with the previews but thought that due to what I saw with other aspects of Forms, that I would run into this problem as well.

I think that because you are using javascript, while you are actually inserting into view these documents, you are not actually saving that view to the saved HTML that is used to generate the PDF when saving to the repository.

Have you tried using the "append" method to add in the HTML equivalent to what you are trying to accomplish? I think the appendChild might be giving you the trouble you are experiencing.

The code in your JSFiddle runs when the image is uploaded, which is great for the initial submission. You'll also need to handle the case where the image is already uploaded and present on the form. This will make your image previews show up later in the process.

The code for signatures actually has something like this already, where the signature image is captured on the form and then HTML encoded and stored in a field. When the form opens later, the data is decoded back into an image and placed on the form.

So if we follow the information on that first link, we should be able to store these images directly when the form is saved? Would it potentially be able to be modified to save an image of an iFrame when a user hits submit?

If you get the image to show up on the form when the form loads, it should appear on the copy saved in Laserfiche.
