Newbie - Problem Two - Ruby and Form Variables, re-loading like PHP_SELF

[page77.office]

I am attempting to copy a PHP project I did in Ruby.

I basically have a search form / web page, which looks for matching
records and displays them prior to the search box form.

I reload the page with

<FORM action="<?php print $_SERVER['PHP_SELF'];?>" method="POST" name =
"Nextrec" >

I then use the isset function to test whether any records have been
displayed and skip the display and go straight to the form. I know
this could have been achieved with javascript, but that was a no no.

I have discovered require cgi and it sems to give me all the info I
need, but how do I replicate the form button action re-loading the page
with all the variables in tact.

Thanks

Richard

"Nextrec" >

If I remember my PHP correctly, $_SERVER['PHP_SELF'] is simply the
name of the currently executing file. The Ruby equivalent is
__FILE__.

Actually, you'll also need to call basename(). So,

basename($_SERVER['PHP_SELF'] ) == __FILE__

Thanks for the replies, and yes PHP_SELF is the name of the running
current page.

I am sorry to be stupid, but how do I get the form action to execute
basename(__FILE__) as I did with:

<FORM action="<?php print $_SERVER['PHP_SELF'];?>" method="POST"

Thanks again

basename() is a PHP function, not a Ruby one.

basename() is a PHP function, not a Ruby one.

$ ri -T File::basename
--------------------------------------------------------- File::basename
File.basename(file_name [, suffix] ) -> base_name
------------------------------------------------------------------------
Returns the last component of the filename given in file_name,
which must be formed using forward slashes (``/'') regardless of
the separator used on the local file system. If suffix is given
and present at the end of file_name, it is removed.

File.basename("/home/gumby/work/ruby.rb") #=>
"ruby.rb"
File.basename("/home/gumby/work/ruby.rb", ".rb") #=> "ruby"
