and
here is my submit.php
<?php
$con=mysqli_connect("localhost", "root", '');
mysqli_select_db($con,"test");
if(isset($_POST['submit']))
{
$num =$_POST['h'];
for($i=0;$i<$num;$i++)
{
$name = $_POST["name_$i"];
$address = $_POST["address_$i"];
$contactNum = $_POST["contactNum_$i"];
mysqli_query($con,"INSERT INTO `com`(`name`, `add`, contact) Values('$name', '$address', '$contactNum')");
}
echo "<h1>Done!</h1>";
}
else
{
echo "not inserted";
}

答案 0 :(得分:0)
INSERT 效果很好,我可以更改代码中的内容
1.if(isset($ _ POST [&#39; submit&#39;]))//提交(大写S)
2. $ i&lt; = $ num //更改为&lt; =
PHP
代码始终是您网页的第一个区块。
<?php
session_start();
if(isset($_POST['Submit']))
{
$num =$_POST['h'];
for($i=0;$i<=$num;$i++)
{
$name = $_POST["name_$i"];
$address = $_POST["address_$i"];
$contactNum = $_POST["contactNum_$i"];
mysqli_query($con,"INSERT INTO `com`(`name`, `add`, contact) Values('$name', '$address', '$contactNum')");
}
}
