我们在使用drupal7中经常使用url中的destination参数做重定性处理,drupal7中也有专门换取url上destination参数的函数,介绍如下:
drupal_get_destination();//这个函数可以获取url中的destination参数,当没有destination参数,函数会将当前url作为参数返回。
drupal_http_build_query(array $query,$parent = '');
drupal_get_query_parameters(array $query = NULL,array $exclude = array('q'),$parent = '');//默认去掉$_GET['q']部分
下面是API中代码:
function drupal_get_destination(){ $destination = & drupal_static(__FUNCTION__);
if( isset( $destination ) ){
return $destination;
}
if( isset( $_GET['destionation'] ) ){
$destionation = array(
'destionation' => $_GET['destination'],
);
}else{
$path = $_GET['q'];
$query = drupal_http_build_query( drupal_get_query_parameters() );
if( $query != '' ){
$path .= '?'.$query;
}
$destination = array(
'destination' => $path,
);
}
return $destination;
}
function drupal_http_build_query( array $query,$parent = '' ){ $params = array();foreach( $query as $key => $value ){ $key = $parent ? $parent . rawurlencode('['.$key.']') : rawurlencode($key);if( is_array( $value ) ){ $params[] = drupal_http_build_query( $value,$key );}else if( !isset( $value ) ){ $params[] = $key;}else{ $param[] = $key . '=' . str_replace('%2F','/',rawurlencode($value));}}return implode( '&',$params );}
function drupal_get_query_parameters( array $query=NULL,array $exclude = array('q'),$parent = '' ){ //set default, if not givenif( !isset( $query ) ){ $query = $_GET;} // if exclude is empty, there is nothing to filterif( empty( $exclude ) ){ return $query;}elseif( !$parent ){ $exclude = array_flip( $exclude );}$params = array();foreach( $query as $key => $value ){ $string_key = $parent ? $parent . '[' .$key .']' : $key;if( isset( $exclude[$string_key] ) ){ continue;}if( is_array( $value ) ){ $params[$key] = drupal_get_query_parameters( $value,$exclude,$string_key );}else{ $params[$key] = $value;}}return $params;}
