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

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

If I remember my PHP correctly, $\_SERVER[‘PHP\_SELF’] is simply the  
name of the currently executing file. The Ruby equivalent is  
**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.

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

basename($\_SERVER[‘PHP\_SELF’] ) == **FILE**

## $ 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”
