我的想法是将数据放在文本字段中并将其传递给数据库MySQL。当文本字段填满并单击按钮时，没有任何反应。当我检查我的数据库时，那里什么也没有。这是为什么？有人可以帮帮我吗？
<?php
//Connection string for the database MySQL
require 'db.php';
//Check if it's set.

答案 0 :(得分：4)
您的SQL查询没有终止分号作为查询的一部分，因此当您连接它们时，服务器无法知道一个查询的结束位置和下一个查询的开始位置。
像这样更新eacch查询：
// Insert query for loan.
$sql = "INSERT INTO loan".
"(Principal_Loan, Interest_Absolute_Amount, Service_Charge, Net_Proceeds)".
"VALUES ('".$principal."', '".$interestAbsoluteAmount."', '".$serviceChargeAmount."', '".$netProceeds."');";
Over there --> Add semi-colon here ^
此外，您应该检查调用mysqli的返回值，以确保不会报告任何错误。如果不这样做，mysqli将无声地失败。
这对于单个查询来说很简单 - 只需检查返回值，如果是错误，请查看mysqli_error()
$result = mysqli_query($con, 'Some Query...');
if ($result === false) {
echo mysqli_error($con);
exit;
}
如果您使用的是multi-query，则会更复杂，因为您必须调用mysqli_next_result()来检查每个查询的返回值。手册here;
除非您有真正的性能问题，否则multi-query()几乎没有任何好处和复杂性。我建议你使用一系列单个查询。如果您担心“全部或全部”更新，请将整个系列包装在一个事务中。
答案 1 :(得分：1)
我在sql语句之间看不到任何分隔符。
mysqli_multi_query：执行一个或多个以分号连接的查询。
