Php 如何对计算表列求和
我需要对显示的表中的一列求和。 我的问题是: 如何对已从其他列计算数据的表列求和？ 我需要使用javascript来完成吗？ 我想在相关列的底部显示总数。 提前感谢您的建议 我当前计算数据的示例：Php 如何对计算表列求和,php,javascript,mysql,joomla,Php,Javascript,Mysql,Joomla,我需要对显示的表中的一列求和。 我的问题是: 如何对已从其他列计算数据的表列求和？ 我需要使用javascript来完成吗？ 我想在相关列的底部显示总数。 提前感谢您的建议 我当前计算数据的示例： echo round(($r->price_sold - $r->shipping - $r->tax - $r->fees) * $r->commission_rate / 100,2); $query = " SELECT * FROM jos_da

在我写一个巨大的答案之前，你在使用库吗？Joomla附带jquery，我想？@Asad-Joomla 3.0附带jquery。Joomla1.5和2.5随mootools一起提供，但导入jQuery并没有错；我很想用这种方法，但我不能让它工作。你能进一步解释一下吗，或者把它插入原代码中应该放在哪里？我可能用错地方了。感谢我制作的工作样本：刚刚更换&36；有了$Thank Boris，它自己就可以工作了，但我无法让它与计算如下的列一起工作：echo；回声&36；；回音轮$r->售价-$r->费用-$r->税收-$r->运费-$r->售价-$r->费用-$r->税收-$r->运费-$r->佣金率/100，2；对于每一列，您可以输入unicue classname并选择像第一列这样的值，然后进行计算。看看，td单元里面是什么。使用Chrome，右键单击单元格->分析元素。向我发送生成的html
