好的，在这个页面上，我想做一个更新。假设页面在视图页面上单击编辑后显示/显示mysql中的数据到文本字段中。但数据似乎无法进入文本字段。这是我的parcelEdit.php代码

我不知道要修复的是什么/请帮助我，因为php对我来说是新的，我仍然适应它。
答案 0 :(得分：0)
要进行编辑，请创建链接：
<a href="parcelEdit.php?email=<?php echo mysql_result($result, $i,'parcelID');?>">Edit</a>
在编辑文件中，您有：
$parcelID = mysql_real_escape_string($_GET['parcelID']);
一旦设置email参数，然后搜索parcelID参数，是否真的看不到？
所以你的编辑链接应该是：
<a href="parcelEdit.php?parcelID=<?php echo mysql_result($result, $i,'parcelID');?>">Edit</a>
ps：你的视图文件很乱......你有：
<body>
<body style='background: url(homebg.jpg)'>
然后你循环生成它。你真的应该先学习一些基本的html语法。
