    <p>I started working on a way to automate creation of my database accessors. I am looking for something compatible with PHP >= 5.2. My first go at it resulted in this: <code><pre>class FancyPDOBase extends PDO{ /////////////////////////////////////////////////////////////////////////////// ////Magic /////////////////////////////////////////////////////////////////////////////// public function __call($method, $args){ if(preg_match('/get[A-Z]{1}[a-z_]*[A-Z]{1}[a-z_]*By[A-Z]{1}[a-z_]*/', $method)){ return $this->getFieldByFields($method, $args); }else if( preg_match('/get[A-Z]{1}[a-z_]*[A-Z]{1}[a-z_]*[A-Z]{1}[a-z_]*Array/', $method) ){ return $this->getPairArray($method); }//Add more expressions here. } /////////////////////////////////////////////////////////////////////////////// protected function getFieldByFields($method, $args){ // Create a series of value getters preg_match('/get([A-Z]{1}.<em>)([A-Z]{1}.</em>)By([A-Z]{1}.*)/', $method, $matches); $table = strtolower($matches[1]); $get = strtolower($matches[2]); preg_match_all('/[A-Z]{1}[^A-Z]*/', $matches[3], $split); $where = self::createWhereStatement($split, $args, $table); $query = "SELECT $get FROM $table $where"; $result = $this->query($query); if($result){ $r = $result->fetchAll(); if(count($r)==1){ return $r[0][0]; }else{ return $r; } }else{ return null; } } //Add more methods here. } </pre></code></p> <p>I am curious if there is someone who has already done this or something very similar, so I don't have to, but I'm also curious if I have missed something in thinking this would be helpful. (My general thinking is that because it extends PDO I could always fall back to a normal SQL query when I need something more complex.)</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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
