Answer 1

我说实话，很难理解你在问什么。我读这个问题的方式是你要创建edit和delete按钮，点击这些按钮会调用一些脚本来更新数据库吗？

嗯，有两种选择：

使用jQuery / PHP的AJAX
非AJAX PHP脚本

我将举例说明＃2将如何运作，您可以根据以下代码谷歌＃1。

你要把按钮放在一个表格中（让我们做delete）：

<强> HTML：

<form method="POST" action="">
<input type="hidden" name="article_id" value="<?php echo $article['article_id']; ?>" />
<input type="submit" value="Delete article" name="delete_article" />
</form>

PHP： - 使用预准备语句显示

    if(isset($_POST['delete_article'])){
    if(isset($_POST['article_id'])){
    $sql = "DELETE FROM table_name 
    WHERE article_id=?";

    if($stmt = $mysqli->prepare($sql)){
    $stmt->bind_param("i", $_POST['article_id']);
    $stmt->execute();
    $stmt->close();
    }


}
}
