php - 使用PHP单击Mysql中的按钮时无法插入
问题描述
我是 web 开发的初学者，我曾经有一个 html 元素，比如文本框和其他类型的元素，我想将它们用作我的对象，当它们有一个值并单击一个按钮时，它将保存所有的值mysql中的元素。
我有这样的代码，但无法插入，单击按钮时也不会发生任何事情。
请帮忙。
PHP：
<?php
define('DB_SERVER', 'localhost');
define('DB_USERNAME', 'root');
define('DB_PASSWORD', '');
define('DB_DATABASE', 'ytp');
$db = mysqli_connect(DB_SERVER,DB_USERNAME,DB_PASSWORD,DB_DATABASE);
if(!$db ) {
die('Could not connect: ' . mysqli_error());
}
$fname = "";
$mname = "";
$lname = "";
$funame = "";
$cnum = "";
$bday = "";
$age = "";
$add = "";
if (isset($_POST['submit'])){
$fname = $_POST['fName'];
$mname = $_POST['mName'];
$lname = $_POST['lName'];
$funame = $_POST['fuName'];
$cnum = $_POST['Cnumber'];
$bday = $_POST['bday'];
$age = $_POST['age'];
$add = $_POST["address"];
}
$sql = "INSERT INTO employee ".
"(fName,mName,lName,fuName,cNumber,bDay,Age,Address) ".
"VALUES ('$fname','$mname','$lname','$funame','$cnum','$bday','$age','$add' )";
if (! mysqli_query($db , $sql)){
echo 'Cannot Insert';
}
else{
echo 'Success';
}
?>

解决方案
您的 HTML 表单在提交按钮之前关闭。您应该在提交按钮后关闭它，并且还需要管理打开表单标签的层次结构，如下所示：
<form method="POST" action="php_functions\saveEmployee.php" name="INSERT">
<div class="card-body">
<div class="row">
<div class="col-md-5 pr-md-1">
<div class="form-group">
<label>Company (disabled)</label>
<input type="text" class="form-control" disabled="" placeholder="Company" value="Benchmark Valuer's Inc.">
</div>
</div>
<div class="col-md-3 px-md-1">
<div class="form-group">
<label>ID</label>
<input type="text" class="form-control" placeholder="User ID" value="" id="id" name ="id" disabled>
</div>
</div>
<div class="col-md-4 pl-md-1">
