Using PHP to identify the current page - by David Powers

Question

Hi There,
I'm trying to write a script so I can identify the sub-pages under "Gallery" in my website
Under Gallery I have more than hundred pages describing the photos but I want to identify them as the "Gallery" page.
How do I achieve that?
It would be tedious to write the "PHP if" statement for each photo link.
I trust there is a simpler solution.
In PHP solutions by David Powers, Ch.4 "Using PHP to identify the current page"
The script is:
<?php $currentPage = basename($_SERVER['SCRIPT_NAME']); ?>
<ul id="nav">
  <li><a href="index.php" <?php if ($currentPage == 'index02.php') {echo 'id="here"';} ?>>Home</a></li>
  <li><a href="journal.php" <?php if ($currentPage == 'journal.php') {echo 'id="here"';} ?>>Journal</a></li>
  <li><a href="gallery.php" <?php if ($currentPage == 'gallery.php') {echo 'id="here"';} ?>>Gallery</a></li>
  <li><a href="contact.php" <?php if ($currentPage == 'contact.php') {echo 'id="here"';} ?>>Contact</a></li>
</ul>
Let's say that the gallery pages contains hundreds of links gallery like gallery/photos1.php, gallery/photos2.php, gallery/photos3.php, gallery/photos4.php, gallery/photos5.php, gallery/photos6.php, gallery/photos7.php etc...
How would I identify the sub-pages so when we are there Gallery is highlighted?
Thank you!
Best,

Hello Siddhardha,
To get the details of a process you need to use Locator class from BPEL api. You can locate your process by listInstances method which accepts WhereCondition parameter used to build a query on process instances. Once you've found the process you were looking for you can use getAuditTrail method to retrieve audit trail of a given instance. You can also use setStatus() method from a BPELX java exec tag within your process and later retrieve it from instance handle by getStatus method.
A sample snippet to retrieve instance handles to all child processes of a given process:
StringBuffer sb = new StringBuffer();
Locator locator = new Locator(domain,domainpassword);
WhereCondition wc = new WhereCondition();
String query = sb.append(SQLDefs.AL_ci_root_id).append(" = ? ").toString();
wc.append(query);
wc.setLong(1,parentInstance);
IInstanceHandle[] ih = locator.listInstances(wc);
