Title: Lookup from image map/hotspot
Post by: Ubaidullah on December 05, 2010, 10:20:27 AM

Hi,

Instead of presenting a list to select from, I want to display an image of a plant and depending on where in the image the user clicked, fill a field with a corresponding value.

How do I go about doing this?

Thanks & Regards,
Ubaidullah Nubar.

Hi Ubaidullah,

First you have to "map" all the different areas in each image and asign a URL to these areas.
The URL will have to take care of filling the field.

A simple but effective image mapping program can be found at

Hi Rene,

Thanks for the reply.

I got the part about mapping the areas. What I need to figure out is how to fill a field based on the area clicked.

Also, thanks for the link.

Thanks & Regards,

Hi Ubaidullah,

In the image mapping you can put the URL of the page itself with attached a variable name and a value.
E.g.

MyPlantPage?plantPart="Description of the plant part."

In the MyPlantPage (which I presume is a form) in the upper part of the GenerateForm routine, you do a p_web.storeValue('plantPart').

On the page itself you define a DisplayField with text-property p_web.gsv('PlantPart')
You can also this field like: p_web.gsv('plantPart') <> ''

I haven't tried this out but it might work. Maybe someone else knows a solution which is much simpler. Who knows...
