List Files

file_list.html


<< 

file_folder="/myworkarea/myfiles"
myEditor="/myworkarea/file_edit.html"
myFiles=FILELIST(file_folder)
myFiles=GETCOLNOTEQ(myFiles,4,"DIR")
>>
<html>
<title>List Files</title>
<table border=0 width=450 cellpadding=2 cellspacing=0 bgcolor=#EEEEEE>
<tr><td colspan=3 bgcolor=#CECECE>
Folder: <b><<file_folder>></b></td></tr>

<tr><td><b>File</b></td>
<td><b>Size (Bytes)</b></td>
<td><b>Last Modified</b></td>

</tr>
<< DISPLAY NAME=myFiles
     ^<tr><td><a href="'+myeditor+'" NAME=file_name

NOTE: This file list is used to provide an automatic list of files in
a folder, each with a link to a file_edit.html. Note that FILELIST
returns files and directories. The GETCOLNOTEQ tag is used to delete
directories from the list returned. Note also how the file_edit.html
file is launced. The variable file_name is set to the file name
using a name=value pair in the link so the editor knows which file to load.
