Pass dynamic data from a link to a form

In WordPress, use the following to extract a string from a URL:

$jobreference = $_SERVER['QUERY_STRING'];


So from a previous page you can add a dynamic string to a link. When it leads to a contact form, the unique string can be extracted and echoed into a form field. For example, from:

http://www.website.co.uk/page?string

$jobreference will be: “string”

Get a Website root, Directory root and File root from PHP

If you want to see what root leads to your file, or if you want to grab breadcrumb links dynamically, you might find the following snippits useful. They will (respectively) echo the current site root, the current directory root and the complete root up to and including the current file name.


echo "Get current site root:";
echo($_SERVER['DOCUMENT_ROOT']);



echo "Get current site root & current directory name:
";
echo dirname(__FILE__);



echo "Get current site root, current directory name & current file name:
";
echo ($_SERVER['DOCUMENT_ROOT'].$_SERVER['PHP_SELF']) ;
