Using BarCode Scanner Input

[look4game]

Hey there people!

The problem is this. I currently want to use a barcode scanner to input a code from a product into its correspondant textfield. The form looks like this and is written in PHP:

The problem is that at the end of the string, the barcode gives an "Enter", which submits the form. This doesn´t let me input the codes for the following products.

Is there a way to make the form "ignore" the Enter Key or something like that?

Thank you 😉

look at the raw output from the scanner. Is it consistant? Once you figure out what exactly it is outputting in ASCII, use substring or preg_replace to clean it up.

I've seen a script in JavaScript which changed the bevaviour of the form, so that Enter moved cursor to the next input field instead of sending form data. You should look for it on some JavaScript-related webpage though.

I did something similar for a data entryform.

the default behavior of [enter] is to submit the form. to change the behavior to set focus to the next item, you'll need a javascript function that is called in the keypress event. That function will get the key press, pass through most of the keys you want, but on enter you'll do your own special handling (like finding the next element and setting focus).

I got the general implementation from javascript code that filtered keypresses.
