Last reviewed: Not reviewed


Builds the HTML code for displaying a standard clickable sort icon.  The alternative text for the image is taken from the current language settings.


string sortIcon ( string $base_href, string $field [, string $state] )

is the base URL that will be used if the user clicks the image.
is the name of the field that is being sorted.
is the current sort state of the field.  This parameter is optional and if omitted will default to 'none'.  Possible values are:
indicates that the field is not currently sorted.  Clicking the image will request an ascending sort.
indicates that the field is currently sorted in ascending order.  Clicking the image will request a descending sort.
indicates that the field is currently sorted in descending order.  Clicking the image will request an ascending sort.


Example: This example (abstracted from the com_statistics component) shows the construction of an array, $sorts, containing the HTML for two sort icons.

// get sort field and check against allowable field names
$field = strtolower( mosGetParam( $_REQUEST, 'field', '' ) );
if (!in_array( $field, array( 'agent', 'hits' ) )) {
  $field = '';
// get field ordering or set the default field to order
$order = strtolower( mosGetParam( $_REQUEST, 'order', 'asc' ) );
if ($order != 'asc' && $order != 'desc' && $order != 'none') {
  $order = 'asc';
} else if ($order == 'none') {
  $field = 'agent';
  $order = 'asc';
// browser stats
$order_by = '';
$sorts = array();
$sort_base = "index2.php?option=$option&task=$task";
switch ($field) {
  case 'hits':
    $order_by = "hits $order";
    $sorts['agent'] = mosHTML::sortIcon( "$sort_base", "agent" );
    $sorts['hits']  = mosHTML::sortIcon( "$sort_base", "hits", $order );
  case 'agent':
    $order_by = "agent $order";
    $sorts['agent'] = mosHTML::sortIcon( "$sort_base", "agent", $order );
    $sorts['hits']  = mosHTML::sortIcon( "$sort_base", "hits" );
$database->setQuery( "SELECT * FROM #__stats_agents WHERE type='0' ORDER BY $order_by" );
$browsers = $database->loadObjectList();
