Pass parameter from one PHP  script to another

I would like to shorten the amount of code in my HTML file to keep it clean.  I have a PHP script which takes the title of a organization's officer, goes to an XML file to look up the current holder's name and email address, then returns a clickable link.  Here's the code:

    $xml_path = "example6/";
    $xml_doc = new DomDocument;

    $xsl_doc = new DomDocument;

    $xp1 = new XsltProcessor();

    $params['title'] = "president";
    $xp1->setParameter("", $params);

    $contact = $xp1->transformToXML($xml_doc);
    if ($contact = $xp1->transformToXML($xml_doc)) {
        return $contact;
    } else {
        trigger_error("XSL transformation failed.", E_USER_ERROR);
    } // if

Open in new window

Is there a mechanism I can use, like "include", so that on one HTML page I can get the president's contact info, and on another page I can get the membership chairman's contact info?  I'm hoping for something simple like:

include getcontact.php ("president");


include getcontact.php?title=president;

Open in new window

I don't understand quite what you have.  If it is truly an HTML page and not a *.php page, you can use AJAX to GET "getcontact.php?title=president" .  But if it is a PHP page, you can simply declare '$params['title'] = "president"' at the top of the page followed by "include getcontact.php;" with that line removed.

HTML doesn't have a 'include' mechanism which is why you would have to use AJAX to get the info.  And when you 'include' a file in PHP, it doesn't run the file at that point, it 'includes' the file text in the current page where it gets run inline with the rest of the page code.  The query string added to the end in that case will get ignored.

And this line with a single '=' is not a comparison but an assignment:

if ($contact = $xp1->transformToXML($xml_doc))

Open in new window

If you want a comparison, it needs to be '==', not '='.

Thanks for the correction on the '=='; I'll update my code with that.

What I have is an HTML page with a lot of content, but in the footer is a paragraph like "Please send corrections to joesmith@test.com".  The PHP code I posted earlier is part of this paragraph, and "joesmith@test.com" is an actual hyperlink.  This hyperlink is created as the page loads.  Because this is a PHP script, I have to name the HTML file with a PHP extension, otherwise the script doesn't do its job.

I want to embed this kind of lookup in several of our website's pages, but for different contacts.  I can create separate standalone PHP scripts, which I have done for testing, for each officer.  For example, in the HTML page I can include getpresident.php.  On another page I can include getlinkseditor.php.  But it seems silly to have multiple scripts when the only thing that changes is the title of the contact.  The XML transformation setup, the data file and the stylesheet all remain constant.

Does my explanation make sense?

to shorten the amount of code in my HTML file to keep it clean...
Usually the correct approach is to lengthen the amount of code, reducing the number of operations to one per line!

You can tell the server to parse .htm and .html files through PHP, just like .php files.  (Especially useful with Dreamweaver).

A sensible design patten might include some OOP code that put all the variables in the right kind of objects.  HTH, ~Ray

I would keep the current method except the code at the top would become 'inline' so that you can use 'echo $contact;' instead of 'return $contact;'.  The php in page would be:

$params['title'] = "president"  // or which ever officer for this page.
include getcontact.php;  // which is the code at the top minus the $params[] line.

Open in new window

That turns 'getcontact.php' into an 'inline function' that is common to all the pages leaving only the value of $params['title'] to be set on each page which it has to be anyway.
