我有一个脚本，为我生成一个表，每次我按下一个按钮，它会产生一个行。如何使用php插入多个表行到数据库
当用户按下提交我想插入到数据库中的所有行一次。我尝试了一些东西，但不工作。我在那里查询只插入一行，但我不知道如何插入多行。
这里是我的代码：
<?php
echo'<!DOCTYPE html>
<html>
<head>

var rows = 1; //for genTab
var cols = 3; //for genTab
var rowCounter = 3; //starts from index 3 when add row on table
var nr = 2; // write the id at the number
var tableId = 1;
var indexTab=0;
function genTab() {
indexTab++;
table += \'<tr> <th class="window_cells" colspan="3"><form name="form[]" id="formId\'+indexTab+\'" class="window_form" action="home.php" method="post"><span>Coordinator: </span><input type="text" name="prof_name" placeholder="Prof. dr.

如果你不得不问问如何插入多行，请比**请保留这个唯一的问题**没有任何HTML的东西，没有其他查询，没有JS代码。 –
我把所有的代码，因为我认为字段名称将在PHP代码中使用。 –
**如果你的问题不是关于SQL插入，而是关于从HTML发送数据到PHP **然后**问这个唯一的问题。没有任何SQL的东西 –
