    <p>I started working with php and mysql today. Basically, what I have, is an empty page with pieces that I fill in from looking up an id in a database. So on my home page I have an url that looks like this: </p> <pre><code>&lt;a href="content/display.php?id=id1"&gt; </code></pre> <p>And then in my display.php I have this:</p> <pre><code>&lt;?php include '../includes/header.php'; $id = $_GET['id']; $mysqli = new mysqli('localhost','username','password','dbname'); if($result = $mysqli-&gt;query("SELECT * FROM portfolio WHERE id='".$id."'")) { while($row = $result-&gt;fetch_object()) { $head = $row-&gt;head; $img1 = $row-&gt;img1; $img2 = $row-&gt;img2; $img_url = $row-&gt;imgurl; $img_thumb = $row-&gt;imgthumb; $vid = $row-&gt;vid; $swf = $row-&gt;swf; $url = $row-&gt;url; $url_text = $row-&gt;urltext; $text = $row-&gt;text; } } else echo $mysqli-&gt;error; ?&gt; </code></pre> <p>It's a sparse table in that not all of those fields will have information (many might be null). Basically they contains file names and then in the html I have code that looks like this:</p> <pre><code>if(isset($img1)) { echo '&lt;img src="images/'.$img1.'" /&gt;'; } </code></pre> <p>A couple of questions,</p> <ol> <li>Is this the best way to do this?</li> <li>Everytime I visit display.php, I am reopening a database connection right? That can't be good...</li> <li>I chose to put the names of the files in the database, rather than entire path names, or even the actual files themselves, figuring that, if I change the name of the file I can go into the database and update it for the file I want to change. If I change the path, I can just change it once in the html. Is that the best idea?</li> </ol> <p>Thanks!</p>

    1. CO(re)opening a database connection is common practice, it shouldn't matter much. I do wonder why you want every property of the object in another variable though?

    2. COI guess so I didn't have to wrap the entire site in that while loop...I suppose I can do that though

Guidance
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.
