 <form id="form1" action="survey.php" method="POST">

Answer 1

重写：

        <form id="form1" action="survey.php" method="POST">
        <table border=1>
        <tr>
            <td height=" 30" width="200">
            Condition of the item received:
            <select name="d1">
                <option>Select One</option>
                <option value="Good">Good</option>
                <option value="bad">bad</option>
                <option value="Worst">Worst</option>
            </select>
            </td>

            <td height=" 30" width="200">
                Price of the Item:
            <select name="d2">
                <option>Select One</option>
                <option value="Good">Good</option>
                <option value="bad">bad</option>
                <option value="Worst">Worst</option>
            </select>
            </td>
        </tr>
        <tr>
            <td align="center" >
                <input type="button" name="submit1"  value="Submit" />
            </td>
        </tr>
        </table>
        </form>

Answer 2

首先，而不是：<input type="button" name="submit1" value="Submit" />

使用：<input type="submit" name="submit1" value="Submit" />

<input type="submit">是用于实际发送表单的内容。

其次，在survey.php的主体中：

<?php
echo "You rated ".$_POST['d1']." for condition."
echo "You rated ".$_POST['d2']." for price."
?>

简而言之：

PHP中的$_POST变量自动设置为包含所有POST参数的字典。

将按钮的ID传递给另一页
