在xml中传递参数 [英] passing parameters in xml
问题描述
我正在尝试使用此代码在xml中实现分页设法使它起作用.虽然它可以完美运行，但是有一个小问题，当我单击NEXT按钮时，它会继续使用相同的初始记录重新加载页面.它不会将用户带到下一页.
i'm trying to implement paging in xml using this code and got around to making it work. while it works perfectly, there is a small issue, that when i click on the NEXT button, it keeps reloading the page with the same initial records. it does not take the user to the next page.
我遇到了此链接，其中发布者也有类似的问题，从答案看来，似乎需要传递参数.但是，那个链接中的家伙正在使用MM_XSLTransform，而我没有.因此，当我尝试在index.php中实现此代码时:
i came across this link wherein the poster had a similar issue, and it seems from the answers parameters need to be passed. however, the guy in that link was using MM_XSLTransform, while i'm not. hence when i try to implement this code in index.php:
$xsl->addParameter("Page", $_GET["Page"]);
$xsl->addParameter("PageSize", $_GET["PageSize"]);
它会引发错误:
Fatal error: Call to undefined method XSLTProcessor::addParameter()
已更新
php代码:
<?php
error_reporting(E_ALL);
ini_set("display_errors", 1);
$xmldoc = new DOMDocument();
if(!file_exists('test.xml')){
echo "Sorry this file does not exists!";
exit();
} else {
$xmldoc->load('test.xml', LIBXML_NOBLANKS);
// Load up the XSL file
$xslDoc = new DomDocument;
$xslDoc->load("test.xsl");
$xsl = new XSLTProcessor;
$xsl->importStyleSheet($xslDoc);
$xsl->setParameter(null, 'Page', $_GET['Page']);
$xsl->setParameter(null, 'PageSize', $_GET['PageSize']);
// apply the transformation
echo $xsl->transformToXml($xmldoc);
}
?>

推荐答案
看看文档xsl模块.您会找到一个 set Parameter方法.
Take a look at the documentation of the xsl module. You will find a setParameter method.
例如
<?php
$doc = new DOMDocument;
$doc->loadxml('<a />');
$proc = getProcessor();
$proc->setParameter(null, 'Page', '99');
$proc->setParameter(null, 'PageSize', '11');
echo $proc->transformToXML($doc);
function getProcessor() {
$doc = new DOMDocument;
$doc->loadxml('<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text" />
<xsl:param name="Page" select="0" />
<xsl:param name="PageSize" select="1" />
<xsl:template name="results" match="/">
Page: <xsl:value-of select="$Page" />
PageSize: <xsl:value-of select="$PageSize" />
</xsl:template>
</xsl:stylesheet>');
$xsl = new XSLTProcessor();
$xsl->importStyleSheet($doc);
return $xsl;
}
打印
Page: 99
PageSize: 11
edit2:试试
<?php
$page = isset($_GET['Page']) ? intval($_GET['Page']) : 0;
$proc = getProcessor();
$proc->setParameter(null, 'Page', $page);
$proc->setParameter(null, 'PageSize', '11');
$doc = getDoc();
echo $proc->transformToXML($doc);
function getProcessor() {
$doc = new DOMDocument;
$doc->loadxml('<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html" />
<xsl:param name="Page" select="0" />
<xsl:param name="PageSize" select="1" />
<xsl:template name="results" match="/">
Page: <xsl:value-of select="$Page" />
PageSize: <xsl:value-of select="$PageSize" />
<hr />
<a><xsl:attribute name="href">?Page=<xsl:value-of select="($Page)-1" /></xsl:attribute>Prev</a>
|
<a><xsl:attribute name="href">?Page=<xsl:value-of select="($Page)+1" /></xsl:attribute>Next</a>
</xsl:template>
</xsl:stylesheet>');
$xsl = new XSLTProcessor();
$xsl->importStyleSheet($doc);
return $xsl;
}
function getDoc() {
$doc = new DOMDocument;
$doc->loadxml('<a></a>');
return $doc;
}
edit3:在您的代码中，您拥有
edit3: In your code you have
index.php?page=<xsl:value-of select="number($Page)-1"/>
使用$ _GET [' p age']代替$ _GET [' P age']或将模板更改为index.php?Page=<xsl:value ....与PageSize/pagesize相同.
Either use $_GET['page'] instead of $_GET['Page'] or change the template to index.php?Page=<xsl:value .... Same with PageSize/pagesize.
