Question

我有2个MySQL表，它们有2个相同的列，一个是temptable，另一个是permanenttable。我以表格的形式向temptable表单显示php的内容。在这种形式中，我希望每个条目都有，我应该有2个选项，Approve和Revoke。我想要做的是，如果我点击Approve，那么temptable中该行的数据会移至permanenttable，或者如果我点击Revoke，则来自temptable被删除。我不知道如何实现它。以下是表单的外观：

我最初尝试做的是单击Approve，我处理SQL查询，然后重定向回到此页面，当此页面再次打开时，我们按下按钮的行将被删除（从它来自temptable）。

我很容易使用SQL查询，但我不明白如何将数据传递到下一个php文件，以便我可以识别要处理的行。

此外，关于如何实现这一目标的任何其他建议将非常有帮助！

编辑1：尝试代码 - 表格：

    $query = "SELECT * from adddoctor";
    $result = mysqli_query($conn,$query);
    $i = 0;
    while($row = mysqli_fetch_assoc($result)){
        $pusername = $row['pusername'];
        $dusername = $row['dusername'];
        echo "<tr>";
        echo "<td>".$pusername."</td>";
        echo "<td>".$dusername."</td>";
        echo "<form method = \"post\" action=\"approve.php\"">";
        echo "<td><input name=\"Approve".md5($pusername + $dusername)."\" type=\"submit\" value=\"Approve\"/></form>";
        echo "<form method = \"post\" action=\"revoke.php\">";
        echo "<input name=\"Revoke".md5($pusername + $dusername)."\" type=\"submit\" value=\"Revoke\"/></td></form>";
        echo "</tr>";
        ++$i;
    }

批准：

$query = "Select * from adddoctor";
        $result = mysqli_query($conn,$query);
        while($row = mysqli_fetch_assoc($result)){
            $pusername = $row['pusername'];
            $dusername = $row['dusername'];
            $hash =  md5( $pusername + $dusername);
            $hash = "Approve" + $hash;
            if(isset($_POST[$hash])){
                $query = "INSERT INTO pdmap values('$pusername','$dusername')";
                $result2 = mysqli_query($conn,$query);
                $query = "Delete from adddoctor where pusername = '$pusername' and dusername = '$dusername'";
                $result2 = mysqli_query($conn,$query);
            }
        }

不要在php使用+中使用.连接。在php 'text' + 'text' = 0中，我认为你混淆了javascript和php。

表格：

$query = "SELECT * from adddoctor";
$result = mysqli_query($conn,$query);
$i = 0;
while($row = mysqli_fetch_assoc($result)){
    $pusername = $row['pusername'];
    $dusername = $row['dusername'];
    echo "<tr>";
    echo "<td>".$pusername."</td>";
    echo "<td>".$dusername."</td>";
    echo "<form method = \"post\" action=\"approve.php\"">";
    echo "<td><input name=\"Approve".md5($pusername . $dusername)."\" type=\"submit\" value=\"Approve\"/></form>";
    echo "<form method = \"post\" action=\"revoke.php\">";
    echo "<input name=\"Revoke".md5($pusername . $dusername)."\" type=\"submit\" value=\"Revoke\"/></td></form>";
    echo "</tr>";
    ++$i;
}
