【问题描述】：
----编辑----- Anwser 发现，而不是按钮，我使用 href 链接将数据传递到另一个 php 文件以进行数据库编辑
下面的代码解决了它
echo "<tr><td>". $row['NAME'] . " " . $row['id'] . "</td><td> <a href='edit.php?edit=$i'>Edit</a>
</td>";
从 mysql 数据库数据生成按钮时。按钮本身似乎不适用于 on click 命令
$i=0;
$redirecrurl = 'location.href=\"TestButtonWorks.php\";';
while($row = mysqli_fetch_array($result))
{
$i= $i+1;
echo "<tr><td><button class=$i onclick = '$redirecrurl'> ". $row['NAME'] . " " . $row['ID'] . " </button></tr></td>";
}
我也试过用一个函数替换网页链接来改变背景颜色，但也不起作用
页面链接： https://crucial-creeks.000webhostapp.com/MainPage.php
它在表格中生成的按钮不起作用，底部添加到列表的按钮工作正常

【问题讨论】：
-
您的引号有语法错误。
-
对我来说效果很好，没有语法错误，无需创建页面位置。
