我试图在地址簿中为我的联系人创建删除按钮。但每次我点击＆＃34;联系verwijderen＆＃34;网页自行重置，联系人不会被删除。任何人都可以帮我解决这个问题吗？

您输入的是文字输入，但您没有与之关联的表单，请创建一个并将提交类型更改为submit 

<form action="delete_contact.php" method="post">
//other inputs 
<input type="submit" name="delete_contact" class="btn btn-succes" value="Contact verwijderen">
</form>

答案 1 :(得分：0)

您正在混合MySQL和MySQLi个功能：

mysqli_query ($query);

if (mysql_affected_rows() == 1)

您不能将MySQL与MySQLi混合，您的代码应为：

mysqli_query ($query);

if (mysqli_affected_rows($conn) == 1)

答案 2 :(得分：0)

添加常规链接以删除联系人，您不需要表单。
