XSLT Combobox Variable Passing
I am trying to create a variable that is displayed to the user after a combobox selection is made. I am using PHP to transform the data and that is all working but when the user selects an option it displays their results but, does not keep the selected option in the combobox. I would also like to display it as a title so the user knows where they are at. Here is the xsl that I have so far. I think my main problem is when I do the transformation after the selection, I am returning a dataset and I don't know how to use PHP inside XSLT. Being able to code I would really like to figure out how to pass variables between PHP and XSL.
Any help would be great! Thanks
<form id="frmID" action="/index.php" method="get">
<select id="choice" name="choice" onchange="this.form.submit()">
//How do I get a variable to hold a value between transformations?
<xsl:value-of select="@choice" />
<input type="hidden" id="page" name="page" value="suppliers" />
