/* Menu Bar v.1.0 by Rob Fisher
24 August 1998

This script is designed to be included in a file. Every time
it is called, it scans the parent file's directory for other
html/phtml pages and prints a bar of links to those pages. The
displayed name of the link is taken from that page's <TITLE>
tag. If no such tag is found, then the link is not printed.

The first and last elements in the bar are default links,
perhaps to the top of your document tree and the top of
the current area. The second element, titled "up" just links
to the parent directory.

I use this script in our internal pages, and it works nicely
and safely for me, though I can't guarantee absolutely that
you'll be so lucky. Feel free to hack it about however you
like.

Have fun, and feel free to contact me at r.d.fisher@hud.ac.uk

/* First, create a function to print the links themselves. This
makes it easy to change the look of the whole bar in one go.

If you want to display the bar more than once in a single page,
you'll have to move echo_link() out of this file or you'll get
an error for trying to declare the same function twice. */

function echo_link($col, $link, $text) {
echo "<TD BGCOLOR=\"$col\" ALIGN=CENTER VALIGN=MIDDLE>\r";
echo "<A ";

/* by default, inline style is used to print the links in
a small, white, sans-serif font with no underline */

echo "STYLE=\"text-decoration: none; font-weight: bold; ";
echo "font-family: ariel, helvetica, sans-serif; ";
echo "color: #FFFFFF; font-size: small\" ";

echo "HREF=\"$link\">$text</A></SMALL></TD>\r";
}

// Okay, let's open the TABLE and print the first default link

echo "<TABLE WIDTH=\"100%\"><TR>\r";
echo_link("#114711", "/index.phtml", "home");

// Now, the "up" link

echo_link("#111146", "../", "up");

/* If you're including this script from a function, you'll need
to make $SCRIPT_FILENAME a global variable. */

if (!$SCRIPT_FILENAME)
global $SCRIPT_FILENAME;

// We'll have to loop through all the files in the current directory

$d = dir(dirname($SCRIPT_FILENAME));
while($file=$d->read()):

/* we don't want this file or any directories, but we do want all
.html and .phtml files */

if (($file != basename($SCRIPT_FILENAME)) && (is_file($file))
&& eregi("html$", $file)):
$fp = fopen("$file", "r");

$build = "";
$flag = 0;

for ($i = 0; !feof($fp); $i++) {
$line = fgets($fp, 1024);

/* The <TITLE> tag MUST be opened at the
beginning of a new line */

if (ereg("^<TITLE>", $line))
$flag = 1;

if ($flag == 1)
$build = $build.$line;

if (ereg("</TITLE>", $line))
$flag = 0;
}

if ($build > ""):
$build = ereg_replace("<TITLE>", "", $build);
$build = ereg_replace("</TITLE>", "", $build);
$build = trim($build);
echo_link("#111111", $file, $build);
endif;
endif;

endwhile;

// To finish off the bar, the other fixed link

echo_link("#114711", "/intranet/index.phtml", "intranet");
echo "</TR></TABLE>";

// and finally, close the directory

$d->close();
?>

to the author/anyone who downloads this, it may be a good idea to make all those ereg`s into eregi`s and ereg_replace into eregi_replace, that kinda got me when i tried to get it working, all my pages had <title> instead of <TITLE> :)
