    <p>I would do something like this:</p> <pre><code>$fields = array( 'titulo', 'tipo_produto', 'quantidade_peso', 'unidade_de_venda', 'unidades_por_caixa', 'caixas_piso', 'pisos_palete', 'tipo_de_palete', 'unidades_palete', 'caixas_palete', 'uni_diametro', 'uni_largura', 'uni_profundidade', 'uni_altura', 'uni_peso_bruto_unidade', 'caixa_largura', 'caixa_profundidade', 'caixa_altura', 'altura_palete', 'volume_unidade', 'peso_caixa', 'peso_palete' ); $sql = 'INSERT INTO ficha_item ( %s ) VALUES ( %s )'; // make a list of field names: titulo, tipo_produto /*, etc. */ $fieldsClause = implode( ', ', $fields ); // make a list of named parameters: :titulo, :tipo_produto /*, etc. */ $valuesClause = implode( ', ', array_map( function( $value ) { return ':' . $value; }, $fields ) ); // or, with create_function $valuesClause = implode( ', ', array_map( create_function( '$value', 'return ":" . $value;' ), $fields ) ); $sql = sprintf( $sql, $fieldsClause, $valuesClause ); // $sql is now something similar to (formatted for display): // INSERT INTO ficha_item // ( titulo, tipo_produto /*, etc. */ ) // VALUES // ( :titulo, :tipo_produto /*, etc. */ ) $stmt = $db-&gt;prepare($sql); // if the keys in $_POST match with $fields, you can now simply pass $_POST here $stmt-&gt;execute( $_POST ); // or, as per Bill Karwin's sound suggestion, with the intersection of $_POST $stmt-&gt;execute( array_intersect_key( $_POST, array_flip( $fields ) ) ) </code></pre> <p>In other words, use named parameters, and have them be dynamically generated based on the <code>$fields</code> array. Although named parameters are not strictly necessary; they <em>do</em> help make things easier, because the order of elements passed to, for instance, <code>PDOStatement::execute()</code>doesn't matter now anymore.</p> <p><s>This assumes though, that the number of elements and their keys in <code>$_POST</code>, exactly match the number of fields and their names in <code>$sql</code>.</s></p>

    1. CO+1 but I would recommend restricting the parameter values: `$stmt->execute(array_intersect_key($_POST, array_flip($fields)))`.

    2. COCombined with Bill's input, this looks good. My test server is not running PHP 5.3 though, could I get an example using create_function? (PHP versions below 5.3 don't support anonymous functions), I tried implementing this on my own, but my PHP newbie-ness is impairing me!

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.

SQuiL has stopped working due to an internal error.

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