因此，这里是我的html如何从动态输入字段保存值以及非动态使用PHP？
<form method="post">
<div class="form-group">
<label for="Firstname">Firstname</label>
<input type="text" class="form-control" id="Firstname" name="firstname" placeholder="Enter firstname">
</div>
<div class="form-group">
<label for="Lastname">Lastname</label>
<input type="text" class="form-control" id="Lastname" name="lastname" placeholder="Enter lastname">
</div>
<div class="form-group">
<label for="Contact">Contact</label>
<input type="number" class="form-control" id="Contact" name="contact" placeholder="Enter contact number">
</div>
<div class="form-group">
<label for="Email">Email</label>
<input type="email" class="form-control" id="Email" name="email" placeholder="Enter email address">
</div>
</div>
<div class="col-lg-6">
<div class="form-group">
<div class="form-group">

<input type="text" class="form-control" id="Username" name="username" placeholder="Enter email">

<div class="form-group">
<div class="form-group">

<input type="password" class="form-control" id="Password" name="password" placeholder="Enter email">
</div>
<div class="form-group">
<div class="form-group">
<label for="CPassword">Confirm Password</label>
<input type="password" class="form-control" id="CPassword" name="cpassword" placeholder="Enter email">

这里是我的PHP代码
<?php
if(isset($_POST["testsave"])){
$firstname=$_POST['firstname'];
$lastname=$_POST['lastname'];
$contact=$_POST['contact'];
$email=$_POST['email'];
$username=$_POST['username'];
$password=$_POST['password'];
$cpassword=$_POST['cpassword'];
$day=$_POST['day'];
$start=$_POST['start'];
$end=$_POST['end'];
$number = count($_POST["day"]);
$sql = "SELECT coalesce(MAX(cashier_id), 0) AS maxx FROM tbl_cashiers";
$result = $DBcon->query($sql);
if ($result->num_rows > 0) {
while($row = $result->fetch_assoc()) {
$cashier_id=$row["maxx"];
}
$cashier_id++;
} else {
$cashier_id=1;
}
if($number > 0){
foreach($day as $key => $n) {
$dday=$day[$key];
$sstart=$start[$key];
$eend=$end[$key];
$sql = "INSERT INTO tbl_shifts (cashier_id, shift_day, shift_start,shift_end)
VALUES ('$cashier_id','$dday','$sstart','$eend')";
if ($DBcon->query($sql) === TRUE) {
}
}
/* $sql2 = "INSERT INTO tbl_cashiers (username, password, firstname,lastname, contact, email)
VALUES ('$username','$password','$firstname','$lastname','$contact','$email')";
if ($DBcon->query($sql2) === TRUE) {
$last_id = $DBcon->insert_id;
} */
}
}
?>
注意注释代码。我想将这些数据保存到两个表中，但是这样只保存第一个数组的DAY，START和END值。 我在想，为什么把这个放在foreach循环结束时会停止循环。请赐教。
PS：评论的代码实际上没有评论在这里，我只是强调了它。
