facebook画布会话问题在ie [英] facebook canvas session problems in ie

问题描述

我已经使用Facebook画布方法构建了一个应用程序。这在Mozilla中工作，但不在IE中。问题是我使用了PHP会话的面包屑功能。在IE中，会话不被记住，每次都会覆盖面包屑数组，而不是附加到数组。

  session_start（）; 
 
 //获取当前所选类别并添加到breadcumbs数组
 if（isset（$ _ GET ['cat_parent_id']））{
 $ cat_parent_id = $ _GET ['cat_parent_id' ]。 
 $ cat_name = $ _GET ['cat_name']; 
 if（$ cat_parent_id == 0）{
 $ _SESSION ['breadcrumbs'] =''; 
} else {
 //如果已选择的类别已经在面包屑数组中，则在该类别之后删除面包屑
 $ position = array_search（$ cat_parent_id，array_keys（$ _ SESSION ['breadcrumbs']））; 
 //如果找到一个位置，拼接数组。 
 if（$ position！== FALSE）{
 // if（$ position == 0）{$ position = 1; } 
 array_splice（$ _ SESSION ['breadcrumbs']，（$ position + 1））; 
} else {
 $ _SESSION ['breadcrumbs'] [$ cat_parent_id] = $ cat_name; 
} 
} 
} else {
 $ cat_parent_id = 0; 
 $ cat_name =''; 
 $ _SESSION ['breadcrumbs'] =''; 
} 
  

任何人都可以帮助？

I have built an app using the facebook canvas method. This works in Mozilla but not in IE. The problem is with a breadcrumbs feature I have using PHP sessions. In IE the session is not remembered and the breadcrumb array is overwritten each time instead of appending to the array.

session_start();

//get current selected category and add to breadcumbs array
if (isset($_GET['cat_parent_id'])){
    $cat_parent_id = $_GET['cat_parent_id'];
    $cat_name = $_GET['cat_name'];
    if ($cat_parent_id == 0){
        $_SESSION['breadcrumbs'] = '';
    } else {
        //if selected category already in breadcrumb array, remove breadcrumbs after that category
        $position = array_search($cat_parent_id, array_keys($_SESSION['breadcrumbs']));
        // If a position is found, splice the array.
        if ($position !== FALSE) {
            //if ($position == 0){ $position = 1; }
            array_splice($_SESSION['breadcrumbs'], ($position + 1));
        } else {
            $_SESSION['breadcrumbs'][$cat_parent_id] = $cat_name;
        }
    }
} else {
    $cat_parent_id = 0;
    $cat_name = '';
    $_SESSION['breadcrumbs'] = '';
}

Can anyone help?
