从php生成的表更新sql表
我正试图通过php生成一个表，该表的下拉框中会根据该ID下的数据库中的内容充满可选择的选项。问题是，我还想根据用户输入到下拉框中的内容更新该表，但这并不是我的运气 表生成工作得非常好从php生成的表更新sql表,php,mysql,Php,Mysql,我正试图通过php生成一个表，该表的下拉框中会根据该ID下的数据库中的内容充满可选择的选项。问题是，我还想根据用户输入到下拉框中的内容更新该表，但这并不是我的运气 表生成工作得非常好 echo "<form id='RemarketingRollCall' method='POST'>"; echo "<tr>"; echo "<td name='ID[]' contenteditable='false' align='center' width

我在当前代码中做错了什么？我不明白为什么这不起作用。我很抱歉，我的问题是，我在当前代码中做错了什么？因为我不明白为什么它不更新。在打开PHP标记后立即将错误报告添加到文件的顶部例如，我刚刚注意到您的查询已经有mysqli_error$con，因此这应该会引发一个错误，您没有共享。如果您还没有看到这些，那么您的代码还没有实现。而且，您的代码没有任何价值。您不需要把它放得太深。您可以在循环之前让查询处于外部，然后使用条件调用它。此外，将foreach行的结构更像foreach array_表达式$key=>$value类型的结构，这样更容易、更清晰，所以不需要列出每一行。
