I have "discovered" something very interesting in my wonderings through HTML and various permeations of forms. (Yes, this is basic stuff!) You can have multiple submit buttons, like so... <input type="submit" name="options" value="Yes"> <input type="submit" name="options" value="No"> <input type="submit" name="options" value="Maybe"> And if you hit the second button, the browser will return... options=No This makes it real nice to have an semi-smart cgi to deal with the same data slightly different depending on which button the user selected. You can also use an image for a submit button. So, based upon the above example, ands the fact you can have images as submit buttons, I can theorize the following... <input type="image" scr="/images/yes.gif" name="options" value="yes"> <input type="image" scr="/images/no.gif" name="options" value="no"> <input type="image" scr="/images/maybe.gif" name="options" value="maybe"> And if you hit the second button (just like the previous), the browser will return... options=No But this is not the case. The browser returns... options.x=25&options.y=10 This is the coordinates where the mouse clicked on the graphic. This information is fine if I have an image map as a multiple submit buttons, or a single image supporting a single submit button. But what if I want multiple images to represent multiple submit buttons? I could simply modify my submit code as such... <input type="image" scr="/images/yes.gif" name="opt-yes" value="yes"> <input type="image" scr="/images/no.gif" name="opt-no" value="no"> <input type="image" scr="/images/maybe.gif" name="opt-maybe" value="maybe"> With this change in the NAME, I would get the following results... opt-no.x=25&opt-no.y=10 With this output, I would have to modify my cgi to parse the return string and toss out anything after period. Somewhat a minor task, but annoying on the whole. The reason for this letter is not to simply rant, or to teach you about submit buttons and images, but to propose a simple solution. Since the normal button returns the NAME and VALUE in a readable format, and the image button returns coordinates in a nice parsing fashion, I would like to propose that the image submit button return both the data types in the following manner... option=25&option=10&option=no This gives us both sides of the coin so developers can use which ever method they need to use for whatever purpose they need it for. I hope this will spark some discussion on this subject. Walter Torres PS: Forgive me if this is not the proper form for this type of thing. I seems like the best place I could find to talk about this issue.
