    <p>I'm fairly new to both PHP and Javascript, so please forgive my ignorance and poor use of terminology, but I'll do my best to explain exactly what I'm struggling to achieve.</p> <p>I have information stored in a PHP array that I call to my index page using the function below (the code below is in a separate PHP file called articles.php that's included in my index.php) : </p> <pre><code>&lt;?php function get_news_feed($article_id, $article) { $output = ""; $output .= '&lt;article class="img-wrapper"&gt;'; $output .= '&lt;a href="article.php?id=' . $article_id . '"&gt;'; $output .= '&lt;div class="news-heading"&gt;'; $output .= "&lt;h1&gt;"; $output .= $article["title"]; $output .= "&lt;/h1&gt;"; $output .= "&lt;p&gt;"; $output .= "Read more..."; $output .= "&lt;/p&gt;"; $output .= "&lt;/div&gt;"; $output .= '&lt;div id="news-img-1"&gt;'; $output .= "&lt;/div&gt;"; $output .= "&lt;/a&gt;"; $output .= "&lt;/article&gt;"; return $output; } $articles = array(); $articles[] = array( "title" =&gt; "Andy at NABA", "description" =&gt; "Docendi, est quot probo erroribus id.", "img" =&gt; "img/gym-01.jpg", "date" =&gt; "05/04/2013" ); $articles[] = array( "title" =&gt; "Grand Opening", "description" =&gt; "Docendi, est quot probo erroribus id.", "img" =&gt; "img/gym-01.jpg", "date" =&gt; "05/04/2013" ); ?&gt; </code></pre> <p>My index.php looks like the following minus some HTML that plays no role in this process:</p> <pre><code>&lt;?php include("inc/articles.php"); ?&gt; &lt;?php $pageTitle = "Home"; include("inc/header.php"); ?&gt; &lt;section class="col-4 news"&gt; &lt;?php $total_articles = count($articles); $position = 0; $news_feed = ""; foreach($articles as $article_id =&gt; $article) { $position = $position + 1; if ($total_articles - $position &lt; 2) { $news_feed .= get_news_feed($article_id, $article); } } echo $news_feed; ?&gt; &lt;/section&gt; </code></pre> <p>I am aiming to dynamically change the CSS Background-Image property of the div element with ID <strong>news-img-1</strong> using Javascript.</p> <p>I have tried such things as:</p> <pre><code>document.getElementById('news-img-1').style.backgroundImage = 'url('&lt;?php $article["img"]; ?&gt;')'; document.getElementById('news-img-1').style.backgroundImage = 'url('http://www.universalphysique.co.uk/' + '&lt;?php $article["img"]; ?&gt;')'; document.getElementById('news-img-1').style.backgroundImage = 'url('window.location.protocol + "//" + window.location.host + "/" + '&lt;?php $article["img"]; ?&gt;')'; </code></pre> <p>.....but I'm getting nowhere!! My code in practise works because the following Javascript inserts an image correctly:</p> <pre><code>document.getElementById('news-img-1').style.backgroundImage = 'url("img/gym-01.jpg")'; </code></pre> <p><a href="http://www.universalphysique.co.uk/" rel="nofollow">Here is my site up and running</a>, the images should be placed in the empty circles you'll see! Any help would be great, this ones tough for me!!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
