Question

我尝试更新像这样的多行

$ID = $_POST['ID'];
$size = count($_POST['compo']);

while ($i < $size) {

    $compo = $_POST['compo'][$i];
    $fill = $_POST['fill'][$i];
    $query = "UPDATE Invantsion Set compon='".$compo."',Num='".$fill."' where ID='".$ID."'";
    ++$i;
}

帖子上的代码是从零件到...

<tr>
    <td align="center"><span lang="he"><font size="2" face="Arial">
	<?php
        echo "<input type='hidden' name='compo[$i]' value='".$row['compon']."'>".$row['compon']."";
	?>
	</font></span>
    </td>
    <td>
        <select name='fill[$i]' style="border: 1px solid #000000; padding-left: 4px; padding-right: 4px; padding-top: 1px; padding-bottom: 1px; background-color: #FFFFFF; font-family:Arial; font-size:8pt; font-weight:bold">
    <?php
        $Uid = $row['id'];
        require( dirname( __FILE__ ) . '/com.php' );
     echo "</select>";
    }
    ?>

获取mysql的新数据的人以及获取MYSQL原始数据的sec部分

while ($row = mysqli_fetch_array($result)) {
echo "<input type='hidden' name='ID' value='".$row['ID']."'>"; 
?>
	<tr>
		<td align="center"><span lang="he"><font size="2" face="Arial">
		<?php
		echo $row['compon'];
		?>
		</font></span>
        </td>
		<td align="center"><span lang="he"><font size="2" face="Arial">
		<?php
		echo $row['Num'];
		?>
		</font></span>
        </td>
    </tr>

如果我得到错误500或只是最后一个结果应该是什么 UPDATE Invantsion Set compon ='DECODERS'，Num =''其中ID = '30' 如果我尝试使代码循环后只有单词后设置它没有什么都不做.. 任何人？
