Question

我有一个显示MySQL表数据的表。我有一个额外的列，为每个条目添加一个复选框。

是否可以将该列行与包含MySQL数据的列中的其他数据相关联？

按下＆＃39; Save＆＃39;然后将复选框条目保存到新的mysql表中。按钮。

这是一张图片，向您展示我的意思：

代码：

<?php

$connection = mysql_connect('localhost','admin','root');

if( isset($_POST['submit']) )
{
    if( isset( $_POST['cb_change'] ) && is_array( $_POST['cb_change'] ))
    {
        foreach( $_POST['cb_change']  as $emp_number => $permission)
        {
            $sql = "UPDATE `rights` SET Permission='".mysql_real_escape_string($permission)."' WHERE emp_number='".mysql_real_escape_string($emp_number)."'";
            echo __LINE__.": sql: {$sql}\n";
            mysql_query( $sql );
        }
    }
}
?>

假设您指的是标题为“更改”的选择列表列之后的另一列。使用this ...

在更改列后添加另一个表格单元格

echo "<td> <input type="checkbox" name='fieldName[]' value="<?php echo $row['emp_number']; ?>" > </td>";

在您发布表单后，$ _POST ['fieldName']数组将包含已单击行的ID。

尝试并确保$ row ['emp_number']来自您的表主键，以确保该值是唯一的。
