如何获得用户配置文件图片,以供其他用户使用PHP查看


How to get a users profile pics to be viewed by other users using PHP?

我要找的只是当运行下面的代码并单击专辑或音乐链接时,它会发布到同一页面,对吗?因此,url会根据单击的链接进行更改,并在其末尾添加href。当链接被点击时,我该如何调用以下内容:

<?php echo 'Albums';?>

原始代码:

if(isset($_GET['username']) === true && empty($_GET['username']) === false){
$username       = $_GET['username'];
if(user_exists($username) === true){
$user_id        = user_id_from_username($username);
$profile_data   = user_data($user_id, 'first_name','last_name','email');
?>
    <h1><?php echo $profile_data['first_name']; ?>'s Yor Page</h1>


<div id="navWrapper">

    <ul>
        <li>
            <a href="#"><img src="uploads/profile/blank_profile.gif" width="150" height="150" id="blank_profile"></a>
        </li>
        <nav>
            <ul>
                <li>
                    <a href="?albums">Albums</a>
                </li>
                <li>
                    <a href="?music">Music</a>
                </li>
            </ul>
        </nav>
    </ul>
</div>
<?php
}else{
    echo 'Sorry, that user doesn''t exist';
}
}else{
header('Location: index.php');
exit();
}
include 'includes/overall/overall_footer.php';
?>

现在我已经设置好了链接,点击后会返回yorpage.com/lr/username?相册,当我点击这个链接并转到url yorpage.com/lr/username时,我如何调用php函数或语句?相册?

因此,一个简单的回声就可以用于演示目的,只是为了在点击时获得回报,这就是我想要的。如果你需要更多信息,我不认为你需要。我不是要求为我编码,我可以返回图像或专辑等。我只想知道如何处理被点击的链接,并在点击专辑或音乐链接时返回简单的回声。非常感谢。

我有点迷路了,但据我所知,你的问题是:我如何在url中传递参数,以便在转到url时http://www.example.com/username/albums这是专辑,对吧?

这里有一个类似的例子:

    if (isset($_GET['page'])) {
        $pageArgs = explode('/', $_GET['page']);
        if(isset($pageArgs[0])) {
            $username = $pageArgs[0];   
        } else {
            header('Location: index.php');
            exit();     
        }
        $action = (isset($pageArgs[1])) ? $pageArgs[1] : false;
        switch($action)
        {
            case 'albums':
                print 'These are my albums <br/>';
                break;
            case 'music':
                print 'This is my music! <br/>';
                break;
            default:
                print '
                    <nav>
                        <ul>
                            <li><a href="'.$username.'/albums">Albums</a></li>
                            <li><a href="'.$username.'/music">Music</a></li>
                        </ul>
                    </nav>';
                break;
        }
    }

根据您的需要进行调整。。。

注意:请注意,我将参数改为page而不是username,因此您必须更新您的重写mod规则。我还使用/分隔页面"arguments"。如果你喜欢的话,你可以用"?"(我想,不确定)。。。


下面是一个简单的MVC

index.php

// Find which page is requested
$pageIDs = pageSelector();
// namespaced pages. You can change to real namespaces with:
// $mPage = '''Page''' . $pageIDs[0];
$mPage = 'Page_' . $pageIDs[0];
array_shift($pageIDs);
// Path to Template file (the static elements common to all pages like
// header, footer, logo, navigation, etc...
$templatePath = 'templates/my_template.html';
if(!empty($pageIDs))
    $pageArgs = $pageIDs;
else
    $pageArgs = false;
//create Page Object, the dynamic content divided by sections
//for instance, content, columnA, columnB   
$page = new $mPage($pageArgs);
$template = new Template($templatePath, $page);
//Here's an example of a section
$template->addSection('subNavigation');
print $template;
// PageSelector Function
function pageSelector()
{
    if (isset($_GET['page'])) {
        $pIDs = explode('/', $_GET['page']);    
    } else {
        $pIDs = array('home');
    }
    $pagePath = 'pages/' . $pIDs[0] . '.php';
    if (file_exists($pagePath)) {
        require_once($pagePath);
        return $pIDs;
    } else {
        $pagePath = 'pages/home.php';
        require_once($pagePath);
        return array('home');
    }
}

    public function addSection($newSectionName)
    {
        $this->sections[] = $newSectionName;
    }
    public function __toString()
    {
        $html = file_get_contents($this->path);
        foreach($this->sections as $section) {
            $html = str_replace('[%%'.$section.'%%]', $this->page->show($section), $html);

我可能会感到困惑(因为那是很多文本),但我认为你正在寻找的是关于htaccess的教程。。。使用重写规则以静默方式转换url:

http://domain/[username]/album

http://domain.com?script.php?user=[username]&action=album

或者类似的东西。用户将看到第一个url,但脚本将可以访问$_GET数组中的useraction。。。然后你可以检查

if(isset($_GET['action']) && $_GET['action']=='album'){ //do something...

有很多关于这方面的教程,但这是我找到的第一个。
