Crear pestañas desde PHP

ByLuis

Uno de los aspectos más complicados para aquellos que empiezan dentro del diseño web es la realización de pestañas (tabs). Si necesitas una ayuda para generarlos, puede venirte bien esta clase PHP que con unas simples líneas de código podrás obtener unas pestañas con un resultado más que decente.

Tan solo habrá que ejecutar el siguiente código y se incluirán en tu HTML las etiquetas necesarias para mostrar los tabs, los cuales pueden ser activos, seleccionados y desactivados.

< 

require_once('Static_Tabstrip.php');
$tabs = array(
array('id' => 'tab_1', 'name' => 'First tab', 'active' => empty($_GET['tab']), 'link' => 'example.php', 'mouseover' => 'Visit Google!'),
array('id' => 'tab_2', 'name' => 'Second', 'active' => !empty($_GET['tab']) && $_GET['tab'] === '2', 'link' => 'example.php?tab=2', 'mouseover' => 'Or not...'),
array('id' => 'tab_3', 'name' => 'Third (disabled)', 'active' => false)
);
PrintTabStrip($tabs);
