Submit problems Can't Post
Hello,
I am working with a perl program that has a Submit button for performing a search. The button is a image file, and works correctly as shown in the section of code below:
------------
print $query->image_button(-name=>'search',
-src=>'http://myserver.com/search.gif',
-border=>0);
------------
I would like to remove the image button, and use a regular Submit button, so that a user can simply hit 'Enter' to perform a search instead of physically having to click on the image. I have tried the following code:
-----------
print $query ->submit (-name=> 'search',
-value=>'Submit');
-----------
which ~appears~ to work fine, but never returns any results.
Can anyone shed some light on this for me?

TIA for any and all help!
-Jim

Re: Submit problems [In reply to] Can't Post
presuming that your code works (i couldn't no errors) you just have to substitute the code that prints the image button for :

"print $query->submit('button_name','value');"

it should work this way...

Re: Submit problems [In reply to] Can't Post
Thanks!
I tried, but no luck. Everything I try seems to work OK, but nothing produces search results (or errors).... except using the button_image. I can't understand what is wrong with my script were I can't eliminate that graphic and still have the same functionality. Actually, the boss sayz that as long I can get the 'Enter' key to search (i.e. user inputs search string, hits 'Enter' - results displayed) then its good to go, so I assumed that eliminating the graphic and replacing it with a submit button was the logical solution....

Back to the drawing board I guess....
THANKS for all your help!
-Jim
