?> El codigo funciona bien, pero solo para 1 campo, se repite todas las veces que sea necesario, sin problemas, pero como consigo meter varios campos en la parte que se repite?
Código PHP:
// repeatable
case 'repeatable':
echo '<a class="repeatable-add button" href="#">+</a>
<ul id="'.$field['id'].'-repeatable" class="custom_repeatable">';
$i = 0;
if ($meta) {
foreach($meta as $row) {
echo '<li><span class="sort hndle">|||</span>
<input type="text" name="'.$field['id'].'['.$i.']" id="'.$field['id'].'" value="'.$row.'" size="30" />
<a class="repeatable-remove button" href="#">-</a></li>';
$i++;
}
} else {
echo '<li><span class="sort hndle">|||</span>
<input type="text" name="'.$field['id'].'['.$i.']" id="'.$field['id'].'" value="" size="30" />
<a class="repeatable-remove button" href="#">-</a></li>';
}
echo '</ul>
<span class="description">'.$field['desc'].'</span>';
break;
pero no consigo realizarlo, como añado al foreach otro campo mas y que me lo guarde correctamente?
este es el .js por si alguien se anima a probrar
