如何在最新新闻joomla中添加图像

问题描述：

I need to get separated the image and text of the article, the problem is that they are in one field of the database, so how can i make that in the view i can put the image separated from the text? because i can't put the image and the text togheter, is a mess

<? foreach ($list as $item) :  ?>

                    <?

                        $year = date('Y', strtotime($item->created));
                        $month = date('m', strtotime($item->created));
                        $day = date('d', strtotime($item->created));


                        $shortDescription = cutString($item->introtext, 100);

                    ?>
                    <div class="footerItem">
                    <?= $day; ?>-<?= $month; ?>-<?= $year; ?>
                    <p><a href="<?= $item->link; ?>"><?= $item->title; ?></a></p>
                    <p>
                    <?= $shortDescription; ?>
                    </p>
                    </div>
<?php endforeach; ?>

so i need to put the image like this $item->image - this is what i want, but in joomla latestnews_mod, there is no field with image, and i don't know if i need to write my own, or edit this module, or i need to use other module for this ? And also i cannot get the field $item->category that i need, there is only the CAT_ID, and how can i get the category field??

我需要将文章的图像和文字分开，问题是它们在一个字段中数据库，那么如何才能在视图中将图像与文本分开？因为我不能把图像和文字放在一边，是一团糟 p>

 ＆lt;？  foreach（$ list as $ item）：？＆gt; 
 
＆lt;？
 
 $ year = date（'Y'，strtotime（$ item-＆gt; created））; 
 $ month = date（  'm'，strtotime（$ item-＆gt; created））; 
 $ day = date（'d'，strtotime（$ item-＆gt; created））; 
 
 
 $ shortDescription = cutString（$ item  - ＆gt; introtext，100）; 
 
？＆gt; 
＆lt; div class =“footerItem”＆gt; 
＆lt;？= $ day;  ？＆gt;  - ＆lt;？= $ month;  ？＆gt;  - ＆lt;？= $ year;  ？＆gt; 
＆lt; p＆gt;＆lt; a href =“＆lt;？= $ item-＆gt; link;？＆gt;”＆gt;＆lt;？= $ item-＆gt; title;  ？＆gt;＆lt; / a＆gt;＆lt; / p＆gt; 
＆lt; p＆gt; 
＆lt;？= $ shortDescription;  ？＆gt; 
＆lt; / p＆gt; 
＆lt; / div＆gt; 
＆lt;？php endforeach;  ？＆gt; 
  code>  pre> 
 
 所以我需要把图像放在这个$ item-＆gt;图像 - 这就是我想要的，但在joomla latestnews_mod中，没有 字段与图像，我不知道我是否需要自己编写，或编辑此模块，或者我需要使用其他模块吗？ 而且我也无法获得我需要的字段$ item-＆gt;类别，只有CAT_ID，我怎样才能获得类别字段??  p> 
  div>

I've lost touch with Joomla a bit, so it's entirely possible this is not the easiest way, but could you use regex to pull out the image from the intro-text if it's not specifically given?

You'd need a pattern something like: <img\b[^>]+?src\s*=\s*['"]?([^\s'"?#>]+)

That's taken from this question: Regex to find the first image in an image tag in an HTML document

EDIT: Example using preg_match:

<?php
  // This is the Regex pattern from above.
  $pattern = '/<img\b[^>]+?src\s*=\s*[\'"]?([^\s\'"?#>]+)/'; 

  // Perform the search, matches will be stored in $matches
  preg_match($pattern, $item->introtext, $matches ); 

  echo "Image src is: " . $matches[1] . "
";
?>

Do note that this is relatively untested, may not work and if it does, may miss cases with bad markup!
