Jochem -

Here is the function:

/* Make page path */
function make_page_path($page_string, $script_name) {
$parts = explode('|', $page_string);
for ($i = 0; $i < count($parts); $i++) {
if ($i == 0) {
$page_path = '&lt;a href="' . $script_name . '"&gt;' .
$parts[$i] . '&lt;/a&gt;';
} else {
$page_path = $page_path . '->' . '&lt;a href="' . $script_name
.. '"&gt;' . $parts[$i] . '&lt;/a&gt;';
}
}
//print("Page_path: " . $page_path . "<br>");
return $page_path;
}

Here is the executing code:

$page_string = make_page_string($page_string, "Search");
$script_string = make_script_string($script_string, "search.php");
print("Page_string: " . $page_string . "<br>");
print("Script_string: " . $script_string . "<br>");
print("Url: " . $url . "<br>");
$page_path = make_page_path($page_string, $script_string, $url);
print($page_path);

To see it execute, this URL will do it:
http://209.204.172.137/casesearch/php/search.php?search_text=***&page_string=Home&script_string=home.php


The Title area contains

&nbsp;&nbsp;<? print($page_path); ?>


The function that creates the link(s) is


/* Make page path */
function make_page_path($page_string, $script_string, $path) {
$scripts = explode('|', $script_string);
$pages = explode('|', $page_string);
for ($i = 0; $i < count($scripts); $i++) {
if ($i < count($scripts) - 1) {
if ($i == 0) {
$page_path = '&lt;a href="' . $path . $scripts[$i] . '"&gt;'
.. $pages[$i] . '&lt;/a&gt;';
} else {
$page_path = $page_path . '-&gt;' . '&lt;a href="' . $path .
$scripts[$i] . '"&gt;' . $pages[$i] . '&lt;/a&gt;';
}
} else {
if ($i == 0) {
$page_path = $pages[$i];
} else {
$page_path = $page_path . '-&gt;' . $pages[$i];
}
}
}
//print("Page_path: " . $page_path . "<br>");
return $page_path;
}




Thank you for your help...
