[英]Retrieving a list of media in umbraco
I'm just starting to play with the XSLT system in umbraco where I was hoping to produce a macro which listed all the media under a specific media directory. 我刚刚开始在umbraco中使用XSLT系统,在那里我希望产生一个宏,该宏列出了特定媒体目录下的所有媒体。 I have come across umbraco.library:GetMedia but, frankly, I have no idea what to pass to it in order to get a list of items. 我遇到过umbraco.library:GetMedia,但是坦率地说,我不知道要传递给它什么才能获得项目列表。 The API docs at http://umbraco.org/apiDocs/html/M_umbraco_library_GetMedia.htm seem to suggest that what I probably want is to look up a node (how?) and then pass it in with http://umbraco.org/apiDocs/html/M_umbraco_library_GetMedia.htm上的API文档似乎暗示我可能想要查找一个节点(如何?),然后将其传递给
umbraco.library:GetMedia(<some node id>, true)
How would I go about getting that initial node id? 我将如何获取该初始节点ID?
Subsequently would something like this work? 随后会进行这项工作吗?
<xsl:for-each select="umbraco.library:GetMedia(<SOMEMAGIC>, 'true')">
<li>
<a href="{umbraco.library:NiceUrl(@id)}">
<xsl:value-of select="@nodeName"/>
</a>
</li>
</xsl:for-each>
Here's the same code but updated to work with Umbraco 4.5 or later: 这是相同的代码,但已更新为可与Umbraco 4.5或更高版本一起使用:
<xsl:variable name="images" select="umbraco.library:GetMedia($currentPage/mediaDir, 1)" />
<xsl:for-each select="$images/*">
<li>
<xsl:choose>
<xsl:when test="string(local-name()) = 'Image'">
<a>
<xsl:attribute name="href">
<xsl:value-of select="./umbracoFile"/>
</xsl:attribute>
<xsl:value-of select="@nodeName"/>
</a>
</xsl:when>
<xsl:otherwise>
<!--Do something with the directory-->
</xsl:otherwise>
</xsl:choose>
</li>
</xsl:for-each>
Thanks to some great help from the folks over at in the umbraco forums I figured it out. 多亏了在umbraco论坛上的人们的大力帮助,我才知道了这一点。 The thread is here and the solution is basically this XSLT 线程在这里 ,解决方案基本上是这个XSLT
<xsl:for-each select="umbraco.library:GetMedia($currentPage/data [@alias='mediaDir'], 'true')/node">
<li>
<xsl:choose>
<xsl:when test="umbraco.library:GetMedia(@id, 'false')/data [@alias = 'umbracoFile']">
<a><xsl:attribute name="href">
<xsl:value-of select="umbraco.library:GetMedia(@id, 'false')/data [@alias = 'umbracoFile']"/>
</xsl:attribute>
<xsl:value-of select="@nodeName"/>
</a>
</xsl:when>
<xsl:otherwise>
<!--Do something with the directory-->
</xsl:otherwise>
</xsl:choose>
</li>
</xsl:for-each>
coupled with a media picker control on the page. 以及页面上的媒体选择器控件。
