RE: [webmin-devel] RE: Problem with value assigned to text entry field

[Larry G. <Li...@IS...>]

I don't really know Jamie.  You can tell by the history of my messages that
I am in new teritory with this.  From other ReadParse subroutine examples,
it looks like Webmin's ReadParse function is working correctly.  The most
common example I found was using + to replace a space in input strings for
search engines.  So the ReadParse replacement of a + by a space appears to
be common, I just did not have a clue.  I am glad I checked the code though.
The online docs and your book did not indicate that I could omit the
replacement function.  It was a bonus to find this.

One thing I guess I would be at a loss for though is how would I solve this
problem if I had a multi-part form in which some input would need to have
the + escaped and some would not?

Thanks Jamie!
