I think it would be nice to be able to use the variable $size when the switch $tpl_type = 'select'
Open "/adm/index.php"
Find
$tpl = '<select id="' . $key . '" name="' . $name . '">' . $return . '</select>';
|
Replace by
$size = (isset($tpl_type[1])) ? (int) $tpl_type[1] : 1;
|
|
|
$tpl = '<select id="' . $key . '" name="' . $name . '"' . (($size) ? ' size="' . $size . '"' : '') . '>' . $return . '</select>';

With this modification we can unselect a value without needed to create our own function for adding a choice like "No Value" or "None"
How to use it ?
In ACP file used the 'select' type as below :
For example define the size to '8'
$display_vars = array(
|
'title' => 'FOO_CONFIG',
|
'vars' => array(
|
'legend1' => 'FOO_SETTINGS',
|
'foo_group_id' => array('lang' => 'FOO_GROUP', 'validate' => 'int', 'type' => 'select:8', 'function' => 'group_select_options', 'params' => array('{CONFIG_VALUE}', false, false), 'explain' => true),
|
|
|
'legend4' => 'ACP_SUBMIT_CHANGES',
|
)
|
);
|
After, on submit, we check if no value is selected by using the following code
// We go compare $display_vars with $cfg_array to determine if the type "select" does not have a choice selected.
|
if ($submit)
|
{
|
$display_vars_diff = array_diff_key($display_vars['vars'] , $cfg_array);
|
|
|
foreach ($display_vars_diff as $config_name_diff => $vars_diff)
|
{
|
if (strpos($vars_diff['type'], 'select') === false)
|
{
|
continue;
|
}
|
|
|
$cfg_array[$config_name_diff] = '';
|
}
|
unset($config_name_diff);
|
}
