Body
Your <code>echo</code> call is not needed in this place. Your statement only concatenates strings and does not print them. Additionaly it's not possible to use an <code>if</code> statement inside a string concatenation. However the if shortcut, the so called <a href="http://php.net/manual/en/language.operators.comparison.php#language.operators.comparison.ternary" rel="nofollow">ternary</a> operator is applicable in this situation. And as pointed out in an other answer there is also a space missing before the selected part. <pre><code>for($i=0;$i<count($arrSql);$i++) { $opt .= "<option " .($_GET['pId'] == $arrSql[$i][0]) ? "Selected" : "" ."value=" .$arrSql[$i][0] . ">" .$arrSql[$i][1]. "</option>"; } </code></pre> An alternative using <code>if</code> that might be more clear is: <pre><code>for($i=0;$i<count($arrSql);$i++){ $opt .="<option "; if ($_GET['pId'] == $arrSql[$i][0]){ $opt .= "Selected"; } $opt .= "value=" .$arrSql[$i][0]. ">" .$arrSql[$i][1]. "</option>"; } </code></pre> If you want to, you can even inline the array accesses into the string by using curly braces leading to this last line: (more <a href="http://php.net/manual/en/language.variables.variable.php" rel="nofollow">here</a>) <pre><code>$opt .= "value=${$arrSql[$i][0]}>${$arrSql[$i][1]}</option>"; </code></pre> For the future you might want to enable error output in your scripts. This would have indicated the main error.

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.
