Body
You could use the <a href="http://fr2.php.net/manual/en/language.variables.scope.php" rel="noreferrer"><code>global</code></a> keyword in the function, so <code>$keywords</code> inside the function refers to <code>$keywords</code> outside the function : <pre><code>function printCategoryItems() { global $keyword; if(isset($_GET['keyword'])){ $keyword = $_GET['keyword']; } } printCategoryItems(); var_dump($keyword); </code></pre> This is because variables inside a function belong to the local-scope of the function, and not the global scope (I haven't done any JAVA for a long time, but I think it's the same in JAVA : a variable declared inside a function is not visible from outside of that function). But using global variables is generally not a great idea... a better solution would be to have your function <a href="http://php.net/return" rel="noreferrer"><code>return</code></a> the data ; for instance : <pre><code>function printCategoryItems() { if(isset($_GET['keyword'])){ return $_GET['keyword']; } } $keyword = printCategoryItems(); var_dump($keyword); </code></pre> As a semi-side-note : another solution, still with global variables (not a good idea, again) would be to use the <a href="http://fr2.php.net/manual/en/reserved.variables.globals.php" rel="noreferrer"><code>$GLOBALS</code> superglobal array</a> : <pre><code>function printCategoryItems() { if(isset($_GET['keyword'])){ $GLOBALS['keywords'] = $_GET['keyword']; } } printCategoryItems(); var_dump($GLOBALS['keywords']); </code></pre> Here, no need for the <code>global</code> keyword anymore. And, to finish, you should read the PHP documentation -- especially <a href="http://php.net/manual/en/language.functions.php" rel="noreferrer">the part about Functions</a>.

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.
