PHP variable in JavaScript

Jon_Boy_3

Hi,

Anyone any idea why the JavaScript code below displays the variable I explicitly declared but not the variable defined by the result of the XSL transform? i.e. when you change $foo to $earth there is no output. (my xsl fragment is at the bottom of this message).

Thanks.

PHP Code:

<?php
//XMLXSL Transformation class
require_once('includes/MM_XSLTransform/MM_XSLTransform.class.php');
?>
<html>

<?php
$mm_xsl = new MM_XSLTransform();
$mm_xsl->setXML("http://feeds.feedburner.com/usgs/eqs1day-M25");
$mm_xsl->setXSL("earthquake.xsl");
$earth = $mm_xsl->Transform();
$foo = 'bar';
?>

<?php
echo $earth;
echo $foo;
?>

</html>

XSL fragment:

<?xml version="1.0" encoding="iso-8859-1"?>
<!DOCTYPE xsl:stylesheet [
<!ENTITY nbsp " ">
<!ENTITY copy "©">
<!ENTITY reg "®">
<!ENTITY trade "™">
<!ENTITY mdash "—">
<!ENTITY ldquo "“">
<!ENTITY rdquo "”">
<!ENTITY pound "£">
<!ENTITY yen "¥">
<!ENTITY euro "€">
]>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:feedburner="http://rssnamespace.org/feedburner/ext/1.0" xmlns:geo="http://www.w3.org/2003/01/geo/wgs84_pos#" xmlns:atom10="http://www.w3.org/2005/Atom" xmlns:dc="http://purl.org/dc/elements/1.1/">
<xslutput method="html" encoding="iso-8859-1"/>
<xslaram name="ItemsPerPage" select="20"/>
<xsl:template match="/">

<xsl:for-each select="rss/channel/item">
<xsl:sort select="title" order="descending"/>
<xsl:if test="position() < 2">
<xsl:value-of select="title"/>
</xsl:if>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>

I take it ( echo $earth; ) produces what you expect?

For a start, you need to ensure you are using the xsl: namespace correctly, otherwise the XSL instructions will be ignored.

<[b]xsl:output[/b] method="html" encoding="iso-8859-1"/>
<[b]xsl:param[/b] name="ItemsPerPage" select="20"/>

Secondly, your actual question makes no sense. There is no Javascript variable declared in the XSL. There is a param declaration (ItemsPerPage) but you never set it.

I'm afraid I don't understand.

<xsl:output method="html" encoding="iso-8859-1"/>
<xsl:param name="ItemsPerPage" select="20"/> are just typos in my original post - even when they are set the problem still occurs.

I thought with an XSL fragment (server side) you get the XSL you want, do a XSL transform and this gives you the results of the XSL on a PHP page, say. Why do I have to set a JavaScript variable in the XSL fragment and not from the PHP output?

My code works when you use <?php echo $foo;?> in the script but not
<?php echo $earth;?>, i.e. not with the result of the transform.

Any more help much appreciated.

What do you see when you use view source in your browser?
