将mysql数据显示到php的文本字段中的问题

Question

Okay so, on this page, i want to do an update. 好的，在此页面上，我想进行更新。 Supposed the page shows/displays the data from mysql into the text fields after i click edit on the view page. 假设在我单击视图页面上的编辑后，页面将mysql中的数据显示/显示到文本字段中。 But the data seemed can't be pulled into the text fields. 但是数据似乎无法拉入文本字段。 Here's my codes for parcelEdit.php 这是我的parcelEdit.php代码

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Updating Parcel Details</title>
<link rel="stylesheet" href="css/style.css" />

</head>

<?php 
include('db.php');

if(isset($_POST['update']))
{   
$parcelID = $_POST['parcelID'];
$owner = $_POST['owner'];
$rcv_date = $_POST['rcv_date'];
$pck_date = $_POST['pck_date'];
$status = $_POST['status'];

// checking empty fields
if (empty($parcelID) || empty($owner) || empty($rcv_date)||
empty($pck_date)|| empty($status)) {    

    if(empty($parcelID)) {
        echo "<font color='red'>Parcel ID field is empty.</font><br/>";
    }
    if(empty($owner)) {
        echo "<font color='red'>Owner Name field is empty.</font><br/>";
    }
    if(empty($rcv_date)) {
        echo "<font color='red'>Received Date field is empty.</font><br/>";
    }
    if(empty($pck_date)) {
        echo "<font color='red'>Picked Up Date field is empty.</font><br/>";
    }
    if(empty($status)) {
        echo "<font color='red'>Parcel Status field is empty.</font><br/>";
    }   
} else {    
    //updating the table
    $result = mysql_query("UPDATE parcel SET parcelOwner = '$owner',
dateReceived = '$rcv_date', datePickup = '$pck_date', parcelStatus =
'$status' WHERE parcelID='$parcelID'");

    //redirectig to the display page. In our case, it is index.php
    header("Location: parcelView.php");
}
}
?>
<?php

//getting id from url
if(isset($_GET['parcelID'])){
$parcelID = mysql_real_escape_string($_GET['parcelID']);

//selecting data associated with this particular id
$result = mysql_query("SELECT * FROM parcel  WHERE parcelID='$parcelID'");

while($res = mysql_fetch_array($result))
{
//$mem_id= $res['mem_id'];
$parcelID= $res['parcelID'];
$owner= $res['parcelOwner'];
$rcv_date= $res['dateReceived'];
$pck_date= $res['datePickup'];
$status= $res['parcelStatus'];
}
} else {
$parcelID = '';
$owner = '';
$rcv_date = '';
$pck_date = '';
$status = '';
}

?>
<body>
    <body style='background: url(mailbox.jpg)'>
    <div align="center">
    <h1>Update Parcel Details</h1>
    <form method="post" enctype="multipart/form-data">
        <table>
        <tr>
            <Td> PARCEL ID : </td>
            <td><input name="parcelID" type="text" id="parcelID" value=<?php

I don't know what/which to be fixed please help me as php is new to me i'm still adapting to it. 我不知道要解决的问题/哪个要解决，请帮助我，因为php是我的新手，我仍在适应它。

For edit you create link: 要进行编辑，请创建链接：

<a href="parcelEdit.php?email=<?php echo mysql_result($result, $i,'parcelID');?>">Edit</a>

And in edit file you have: 在编辑文件中，您具有：

$parcelID = mysql_real_escape_string($_GET['parcelID']);

Don't you really see that once you set email parameter and then you search for parcelID parameter ? 设置email参数然后搜索parcelID参数后，您真的看不到吗？

So your edit link should look: 因此，您的编辑链接应如下所示：

<a href="parcelEdit.php?parcelID=<?php echo mysql_result($result, $i,'parcelID');?>">Edit</a>

ps: your view file is one big mess... you have: ps：您的视图文件非常混乱……您有：

<body>
<body style='background: url(homebg.jpg)'>

And you generate it in loop. 然后循环生成它。 You really should learn some basic html syntax first. 您确实应该首先学习一些基本的html语法。
