我在这个网站和其他网站上尝试了其他解决方案，但无法使其正常运行。 当我按下刷新空数据发送到phpmyadmin，并进行空白输入。 当我按下提交时，它不发送任何内容，甚至不是空白。
我的数据库连接正常。 康恩

答案 0 :(得分：0)
您的表单如何？你有“提交”输入吗？
从我在代码中看到的，每次发送表单时都会运行SQL语句，没有任何条件，您最好将查询放在条件括号内，例如：
<?php
if (isset( $_POST['submit'] ))
{
$hvemErDu = $_POST['hvemErDu'];
//connecting to sql database
$conn or die( $conn->error );
//inserting details into table
$insert = $conn->query("INSERT INTO lejere ( `hvemErDu` ) VALUE ( '$hvemErDu' )");
//closing mysqli connection
$mysqli->close;
} else
{
echo 'error';
}
?>
注意你也回应错误 - 我不确定你是否想要回显字符串'error'或变量$ error。
但是，这一次看起来你似乎没有任何记录 - 甚至不是空白记录，你能展示整个表格代码吗？
<强>更新
至于你的代码，请注意当你发布表单时，你将它提交给process.php，该文件是否存在？因为您的代码不起作用，除非您将表单提交到同一页面，如下面的代码：
// Send the form to the same page - index.php
<form method="POST">
<强>更新
你还有另一个问题，你有很多共享同名的输入：hvemErDu。 您必须为每个输入指定一个唯一的名称，否则最新输入的值将被提交给服务器。
这是来自index.php代码：
<label>Kommune 1</label>
<input type="text" name="hvemErDu" class="form-control" id="exampleInputEmail1" placeholder="Kommune du gerne vil have bolig i?">
<label>Navn</label>
<input type="text" name="hvemErDu" class="form-control" id="exampleInputEmail1" placeholder="Indtast navn">
<label>Email</label>
<input type="text" name="hvemErDu" class="form-control" id="exampleInputEmail1" placeholder="Indtast email">
<label>Mobil nummer</label>
<input type="text" name="hvemErDu" class="form-control" id="exampleInputEmail1" placeholder="Indtast mobil nummer">
