問題描述

我正在使用這個 simplepie，并且已將文件上傳到我的主機.除了一件事外，一切似乎都運行良好.我從中獲取提要的博客中有圖像，當我使用 simplepie 查看提要時，圖像不顯示.當我使用 simplepie 查看博客時，有沒有辦法讓圖像顯示出來?

I am using this simplepie and i have uploaded the files to my host. Everything seems to be working fine except one thing. The blog that i'm getting the feed from has images in it, and when i use the simplepie to view the feed, the images don't show up. Is there a way to get the images to show up when i view the blog with simplepie?

好的，對不起，我是新手.我只是直接使用網站上的代碼來嘗試查看博客.我會把代碼放在這里的底部.所以是的，就像我說的那樣，我只是想讓圖像顯示在我正在閱讀的博客上.除了那個之外，一切都很好.

Okay i am sorry, i am new at this. I am just using the code straight from the website to try and view the blog. i will put the code at the bottom here. So yea like i said i'm just trying to get the images to show up that are on the blog i'm reading from. Everything shows up great except that.

--- 頭信息---

<?php

// Make sure SimplePie is included. You may need to change this to match the location of simplepie.inc.
require_once('simplepie.inc');

// We'll process this feed with all of the default options.
$feed = new SimplePie();

// Set the feed to process.
$feed->set_feed_url('http://wordpress.homickdesign.com/feed/');

// Run SimplePie.
$feed->init();

// This makes sure that the content is sent to the browser as text/html and the UTF-8 character set (since we didn't change it).
$feed->handle_content_type();

// Let's begin our XHTML webpage code.  The DOCTYPE is supposed to be the very first thing, so we'll keep it on the same line as the closing-PHP tag.
?>

--- 代碼---

<h2><a href="<?php echo $feed->get_permalink(); ?>"><?php echo $feed->get_description(); ?></a><br />
      <span>Latest news from Robert Homick</span></h2>       

        <?php
$c=1;   
foreach ($feed->get_items() as $item):
if($c <= 3){
?>

        <p><a href="<?php echo $item->get_permalink(); ?>"><?php echo $item->get_title(); ?></a><br />
        <?php echo $item->get_description(); ?><br />
        <span>Posted on <?php echo $item->get_date('j F Y | g:i a'); ?></span><br />
        <?php $c++;?>


<?php } endforeach;  ?>

推薦答案

是的，您可以調用 get_content() 并將整個帖子或包含在提要中的帖子部分輸出到屏幕上，所有包括 HTML 標簽.如果你想拉出帖子中的第一張圖片，你必須做更多的工作，這是我一直在做的.

Yes, you can call get_content() and the entire post or the portion of the post that is included in the feed will be outputted to the screen, all the HTML tags included. If you want to pull say the first image in the post, you have to do a little more work, here is what I've been doing.

$htmlDOM = new simple_html_dom();
$htmlDOM->load($item->get_content());
$image = $htmlDOM->find('img', 0); 
$html .= '<img src="thumbnail.php?file=' . $image->src . '&maxw=300&maxh=300" border="0" />';

我目前的小項目中的片段，使用 simple_html_dom 和另一個我從互聯網上獲取的腳本來即時調整圖像大小.如果您只想顯示圖像根本不調整其大小 $image->src 是 URL.我認為這樣的功能將來可能會添加到 SimplePie 或作為 SimplePie 的附加組件，但同時，顯示來自提要的項目的第一張圖像需要四行代碼.

That snippet from my current little project, uses simple_html_dom and another script I got off the Internet to resize images on the fly. If you just want to display the image not resize it at all $image->src is the URL. I think functionality like this may be added to SimplePie in the future or an add-on to SimplePie, but in the mean time, it is four lines of code to display the first image from an item from a feed.
