我在更新tblitemlist
上的状态字段时遇到问题。我想显示所有status ='PENDING',当它完成时,我想要做的是只需单击一个按钮就可以将其状态更新为已完成。我一个接一个地想要它而不是单击按钮并同时更新所有内容。请帮帮我
这就是我所做的:
$query_update = mysql_query("UPDATE tblitemlist SET status = 'FINISHED'") or die(mysql_error());
我试过这个。没有错误但是当我检查我的数据库时,状态没有改变。
$id=$_GET['id'];
$query_update = mysql_query("UPDATE tblitemlist SET status = 'FINISHED' WHERE id='$id'") or die(mysql_error());
要显示我的代码..

答案 0 :(得分:1)
您必须添加WHERE语句以指定必须更新的表项。首先,您必须使用ID提供查询。例如,每个按钮都会发布&#39; id_to_update&#39;通过表格。
$query_update = mysql_query("UPDATE tblitemlist SET status = 'FINISHED' WHERE id = ".$_POST['id_to_update']) or die(mysql_error());
这就是你想要的吗?
