我正在努力使这项工作。但点击保存后没有弹出任何内容。 与数据库有正确的连接，数据库中的列名也与我给出的相同，重新检查。 新手，需要帮助。 请纠正我的错误，我找不到一个：

请记住，没有父表单或js监听器的提交输入不会做任何事情。因此，最简单的方法是制作一个<form>作为您的页面名称的操作，例如：
<form action="<?echo $PAGE_NAME?>" method="POST" >
<table class="table" align="center">
<tr>
<thead>
<td>year</td>
<td>Area at the starting year</td>
<td>Maximum profit per hectare</td>
<td>Minimum profit per hectare</td>
<td>Area at the ending year</td>
<td>Area in hectare</td>
<td></td>
</thead>
</tr>
<tr>
<td>2011-2012</td>
<td><input type="number" id="areas12" name="areas12"></td>
<td><input type="number" id="maxp12" name="maxp12"></td>
<td><input type="number" id="minp12" name="minp12"></td>
<td><input type="number" id="areae12" name="areae12"></td>
<td><input type="number" id="volume12" name="volume12"></td>
<td>
<button type="submit" class="btn btn-primary btn btn-block">Save</button>
<input type="hidden" name="submitted1" value="1">
</td>
</tr>
