如何将PHP代码添加到URL

-1

我应该使用哪些php代码以及如何将它添加到下一个文章下面的url链接，这将导致多维数组中的下一篇文章随后被回显？如何将PHP代码添加到URL

我打算一个接一个地回显一篇文章。

谢谢！

（form.php的）

<form action="process.php" method="get"> 
    Group: 
    <select name="group"> 
     <option value="group1">Group1</option> 
     <option value="group2">Group2</option> 
    </select> 

    Chapter: 
    <input type="text" name="chapter"> 

    Article: 
    <input type="text" name="article"> 

    <input type="submit" value="Go to Article">  

</form>

（process.php）

<?php 

session_start(); 

$laws=array(
     "group1"=>array(
         "1"=>array(
           "1"=>"This is article (1) in chapter (1) of (group1)", 
           "2"=>"This is article (2) in chapter (1) of (group1)", 
           "3"=>"This is article (3) in chapter (1) of (group1)", 
           ), 
         "2"=>array(
           "1"=>"This is article (1) in chapter (2) of (group1)", 
           "2"=>"This is article (2) in chapter (2) of (group1)", 
           "3"=>"This is article (3) in chapter (2) of (group1)", 
           ), 
         ), 
     "group2"=>array(
         "1"=>array(
           "1"=>"This is article (1) in chapter (1) of (group2)", 
           "2"=>"This is article (2) in chapter (1) of (group2)", 
           "3"=>"This is article (3) in chapter (1) of (group2)", 
           ), 
         "2"=>array(
           "1"=>"This is article (1) in chapter (2) of (group2)", 
           "2"=>"This is article (2) in chapter (2) of (group2)", 
           "3"=>"This is article (3) in chapter (2) of (group2)", 
           ), 

     ) 
     ); 

$grp= $_GET['group']; 
$chap = $_GET['chapter']; 
$art = $_GET['article']; 

if(isset($laws[$grp]) && isset($laws[$grp][$chap]) && isset($laws[$grp][$chap][$art])){ 
$_SESSION['group'] = $grp; 
$_SESSION['chapter'] = $chap; 
$_SESSION['article'] = $art;  
}else{ 
$_SESSION['group'] = 'group1'; 
$_SESSION['chapter'] = '1'; 
$_SESSION['article'] = '1'; 
} 

$group = $_SESSION['group']; 
$chapter = $_SESSION['chapter']; 
$article = $_SESSION['article']; 


echo $laws[$group][$chapter][$article]; // ALL NEXT ARTICLES TO BE ECHOED HERE!!!!! 

?> 

<a href="process.php" style="text-decoration: none;">NEXT ARTICLE</a>

<a href="process.php?group=<?php echo $group; ?>&chapter=<?php echo $chapter; ?>&article=<?php echo ($article + 1); ?>" style="text-decoration: none;">NEXT ARTICLE</a>

将链接到章的下一篇文章。但是你必须检查你是不是在给定章节的最后一篇文章，我将留给你

我已更正您的代码来echo $ article ++ NOT echo（$ article +1）并且它已经工作。但我后来又添加了以前的文章url链接，其中除了$ article之外的代码相同，但无法工作。我该怎么做才能使这两个链接活跃和可行？ – user2075752 2013-02-16 06:22:48
