您好，我正在开发用户管理系统。我显示了数据库中的所有记录，并且添加、编辑和删除操作已成功执行。现在我需要在主页中仅显示 Mysql 表中的事件记录。我的管理控件中有 2 个链接，一个已激活，另一个已停用。如果我单击激活，记录将显示在主页中，停用意味着记录将隐藏在主页中。我插入了字段状态
datatype enum('active','deactive')`.
我的编码如下。在编码中我需要进行哪些更改？
Index.php:
<form method="post">
<table>
<tr>
<td>Title:</td>
<td><input type="text" name="title" /></td>
</tr>
<tr>
<td>Author</td>
<td><input type="text" name="author" /></td>
</tr>
<tr>
<td>Publisher Name</td>
<td><input type="text" name="name" /></td>
</tr>
<tr>
<td>Copyright Year</td>
<td><input type="text" name="copy" /></td>
</tr>
<tr>
<td> </td>
<td><input type="submit" name="submit" value="add" /></td>
</tr>
</table>
<?php
if (isset($_POST['submit']))
{
include 'db.php';
$title=$_POST['title'] ;
$author= $_POST['author'] ;
$name=$_POST['name'] ;
$copy=$_POST['copy'] ;
mysql_query("INSERT INTO `books`(Title,Author,PublisherName,CopyrightYear)
VALUES ('$title','$author','$name','$copy')");
}
?>
</form>
<table border="1">
<?php
include("db.php");
$result=mysql_query("SELECT * FROM books");
while($test = mysql_fetch_array($result))
{
$id = $test['BookID'];
echo "<tr align='center'>";
echo"<td><font color='black'>" .$test['BookID']."</font></td>";
echo"<td><font color='black'>" .$test['Title']."</font></td>";
echo"<td><font color='black'>". $test['Author']. "</font></td>";
echo"<td><font color='black'>". $test['PublisherName']. "</font></td>";
echo"<td><font color='black'>". $test['CopyrightYear']. "</font></td>";
echo"<td> <a href ='view.php?BookID=$id'>Edit</a>";
echo"<td> <a href ='view.php?BookID=$id'>Activate</a>";
echo"<td> <a href ='view.php?BookID=$id'>Deactivate</a>";
echo"<td> <a href ='del.php?BookID=$id'><center>Delete</center></a>";
echo "</tr>";
}
mysql_close($conn);
?>
</table>
View.php:
<?php
require("db.php");
$id =$_REQUEST['BookID'];
$result = mysql_query("SELECT * FROM books WHERE BookID = '$id'");
$test = mysql_fetch_array($result);
if (!$result)
{
die("Error: Data not found..");
}
$Title=$test['Title'] ;
$Author= $test['Author'] ;
$PublisherName=$test['PublisherName'] ;
$CopyrightYear=$test['CopyrightYear'] ;
if(isset($_POST['save']))
{
$title_save = $_POST['title'];
$author_save = $_POST['author'];
$name_save = $_POST['name'];
$copy_save = $_POST['copy'];
mysql_query("UPDATE books SET Title ='$title_save', Author ='$author_save',
PublisherName ='$name_save',CopyrightYear ='$copy_save' WHERE BookID = '$id'")
or die(mysql_error());
echo "Saved!";
header("Location: index.php");
}
mysql_close($conn);
?>

请给出一些想法或编码。这是我第一次使用这个概念。??
最佳答案
使用主动非主动逻辑时..
您必须遵循以下步骤:-
- You have to create some flag status with enum value for active and deactive.
- while fetching data from database you have to give condition to fetch only active record.
- If you have active or deactive button you have to update your record based on that.
如果您遵循这些步骤，它就会起作用!
