I understand what you're saying. You like the convenience of having the
entire thing kept in a neat variable called $file_list, which you can
add to your page in any place that you like, but you need a unique name
for each <select> input tag so that on the "receiving" PHP script, you
can access the contents of each time that you use $file_list.
Unfortunately, I can't think of a good way for you to make these input
names unique. The best thing I can suggest is that you turn this into a
function/subroutine, and pass the string you wish to use as a unique
name to the function as its argument (and you can make this a reuaseable
function by also passing the $dir_name as an argument, and the target of
the form tag). Like this:
// $dir_name = name of directory to list
// $form_target_page = name of page to receive this form's input
// $input_name = unique name for this <select> input
function file_list($dir_name, $form_target_page, $input_name)
{
if (!$dir = opendir($dir_name)) {
return "Could not open directory $dir_name";
} else {
$file_start = "<p><form method=\"post\" action=\"$form_target_page\">
<select name=\"$input_name\">\n";
while ($file_name = readdir($dir)) {
if ($file_name != '.' && $file_name != '..') {
$file_list .= "<option
value=\"$file_name\">$file_name</option>\n";
}
}
closedir($dir);
$file_finish = "</select><br /><br />
<input type=\"submit\" name=\"submit\"
value=\"select\">
</form></p>\n";
// this function prints the form as its return value
return $file_start . $file_list . $file_finish;
}
}
