我的任务是首先使用最新产品（最高数字代码）重新订购网站上显示的所有项目。目前，它们按进入顺序列出。代码将以单字母或双字母开头，然后是数值（即 001-1200）

这是当前带有显示范围和类别的代码的基本页面，我相信该网站/代码大约有 15 年历史......

解决方案 1

更改查询中的排序顺序，使其顺序正确。这是比解决方案 2 更好的解决方案

解决方案 2

向后循环查询。

我已将链接分成几部分以使其更清晰。需要删除换行符。

<cfoutput>
    <cfloop from="#products.recordcount#" to="1" step="-1" index="i">
    <a href="index.cfm?content=product
        &range_id=#range.range_id#
        &category_id=#category.category_id#
        &product_id=#products.product_id[i]#" target="_self" alt="#products.code[i]#">
        <img src="#products.image_1_thumb[i]#" width="88" height="88" border="0" 
            alt="#products.code[i]#" 
            title="#products.code[i]#" style="margin-right:4px;margin-bottom:3px;border: 2px solid ##484848;">
    </a>
    </cfloop>
</cfoutput>

解决方案 2 改进

数据还需要正确编码

<cfoutput>
    <cfloop from="#products.recordcount#" to="1" step="-1" index="i">
    <a href="index.cfm?content=product
        &range_id=#EncodeForURL(range.range_id)#
        &category_id=#EncodeForURL(category.category_id)#
        &product_id=#EncodeForURL(products.product_id[i])#" target="_self" alt="#EncodeForURL(products.code[i])#">
        <img src="#EncodeForHTMLAttribute(products.image_1_thumb[i])#" width="88" height="88" border="0" 
            alt="#EncodeForHTMLAttribute(products.code[i])#" 
            title="#EncodeForHTMLAttribute(products.code[i])#" style="margin-right:4px;margin-bottom:3px;border: 2px solid ##484848;">
    </a>
    </cfloop>
</cfoutput>

解决方案 3

如果您有 CF 2018 更新 5 或更高版本

<cfset products = products.reverse()>
<cfoutput query="products">
   <a href="index.cfm?content=product&range_id=#range.range_id#&category_id=#category.category_id#&product_id=#products.product_id#" target="_self" alt="#products.code#"><img src="#products.image_1_thumb#" width="88" height="88" border="0" alt="#products.code#" title="#products.code#" style="margin-right:4px;margin-bottom:3px;border: 2px solid ##484848;"></a>
</cfoutput>
