This is my first item of contribution, so I might need a bit of guidance. This is a replacement for the default set_value() form helper that supports indexes in form elements. The index must be predefined, so my_field[] will not work, however my_field[2] will.
<?php
function set_value($field = '', $default = '')
{
if (FALSE === ($OBJ =& _get_validation_object()))
{
if(strpos($field, '[') !== false && strpos($field, ']') !== false){
$f = $field;
$field = substr($f, 0, strpos($f, '['));
$index = substr($f, strpos($f, '[')+1, (strpos($f, ']')-1) - strpos($f, '['));
}
if ( ! isset($_POST[$field]))
{
return $default;
}
if( is_array($_POST[$field]) && isset($index) && !empty($index)){
if ( ! isset($_POST[$field][$index]) )
{
return $default;
}
return form_prep($_POST[$field][$index]);
}
return form_prep($_POST[$field]);
}
return form_prep($OBJ->set_value($field, $default));
}
?>
