Javascript 从数据库获取值并显示在html表中，包括PHP
我有一个由用户输入数据的表。行是动态创建的。用户给定的值被发送到DB（Oracle 11g），并根据该值获取其他值并插入到表中。代码如下所示：Javascript 从数据库获取值并显示在html表中，包括PHP,javascript,php,oracle11g,Javascript,Php,Oracle11g,我有一个由用户输入数据的表。行是动态创建的。用户给定的值被发送到DB（Oracle 11g），并根据该值获取其他值并插入到表中。代码如下所示： <!DOCTYPE HTML> <html> <body> <?php $code = $_POST['code']; $qty = $_POST['qty']; foreach ($_POST['code'] as

哦，太好了。它是有效的，但是如何计算总数呢？正如总金额一样？@KaranGupta我更新了我的答案，以回应您的评论，即适应总金额的计算。希望这能解决你的问题，但并没有达到预期的效果。我得到一个错误“第70行中未定义变量sumTotal”，即我们声明“sumTotal”的行。但它也会显示结果，尽管不在表中！）注意：未定义的变量：E:\xampp\htdocs\myfiles\m3.php中的sumTotal在第70行调用堆栈#时间内存函数位置1 0.0005 140960{main}（）…\m3.php:0I修复了错误，在声明sumTotal时没有放置“；”。但它仍然会产生上面的错误。哦，太好了。它是有效的，但是如何计算总数呢？正如总金额一样？@KaranGupta我更新了我的答案，以回应您的评论，即适应总金额的计算。希望这能解决你的问题，但并没有达到预期的效果。我得到一个错误“第70行中未定义变量sumTotal”，即我们声明“sumTotal”的行。但它也会显示结果，尽管不在表中！）注意：未定义的变量：E:\xampp\htdocs\myfiles\m3.php中的sumTotal在第70行调用堆栈#时间内存函数位置1 0.0005 140960{main}（）…\m3.php:0I修复了错误，在声明sumTotal时没有放置“；”。但它仍然给出了上述错误。
