Wordpress 简码不从函数传递变量(新手)

Wordpress Shortcode not passing variable from function (Newbie)

这是有问题的代码片段:

function hoursearned_func($user) {
    $key = 'Service Hours Earned';
    if(isset($user[$key])) {
        $result = $user[$key];
    }
return "Service Hours Earned: ".$result." Hours";
}
add_shortcode('hoursearned', 'hoursearned_func');

这个小函数简单地 returns 给定键的数组的值,但是当调用简码 [hoursearned] 时,它只显示:

Service Hours Earned: Hours

而不是:

Service Hours Earned: 200 Hours

其中 200 是函数 hoursearned_func 给定 $user 返回的字符串。

出于某种原因,Wordpress 没有将函数返回的变量传递给简码。我怎样才能让 Wordpress 显示函数的结果?

如果有帮助的话,这里是完整的代码...(请注意,所有这些都是作为插件加载的)

//Dump CSV file (SalesForce Report) to php array to be parsed..
add_action('dump_csv_array', 'dump_csv_array', 10);
function dump_csv_array(){
    $data = array();
    $header = NULL;
    if (($file = fopen('http://blah.com/info.csv', 'r')) !==FALSE) { //The link to the CSV is insignificant
        while (($row = fgetcsv($file, 1000, ",")) !==FALSE) {
            if(!$header)
                $header = $row;
            else
                $data[] = array_combine($header, $row);
            }
    fclose($file);
    }
    return $data;
}

$multiarray = (array) dump_csv_array();
global $current_user;
get_currentuserinfo();
$user_email = $current_user->user_email;

//Parses the multidimensional array of Dumped CSV info. Looks up the current user's email and returns a single array of the current user's SalesForce information.  
function parse_array($multiarray, $user_email){
    $array = (array) $multiarray;
    $email = $user_email;       
        if(is_user_logged_in() === true ) {
            foreach($array as $subarray) {
                if(isset($subarray['Email']) && $subarray['Email'] == $email) {
                    $data = $subarray;
                }   
            }
        }
        else {
            return NULL;
        }
return $data;
}

$user = parse_array($multiarray, $user_email);

//Defines Shortcodes and their Functions
function hoursearned_func($user) {
    $key = 'Service Hours Earned';
    if(isset($user[$key])) {
        $result = $user[$key];
    }
return "Service Hours Earned: ".$result." Hours";
}


function hoursawarded_func($user) {
$key = 'Service Hours Awarded';
    if(isset($user[$key])) {
        $result = $user[$key];
    }
return "Service Hours Awarded: ".$result." Hours";
}

function rank_func($user) {
$key = 'Rank';
    if(isset($user[$key])) {
        $result = $user[$key];
    }
return "Rank: ".$result;
}

function memstatus_func($user) {
    $key = 'Membership Status';
    if(isset($user[$key])) {
        $result = $user[$key];
    }
return "Status: ".$result;
}

function register($atts) {
    add_shortcode( 'hoursearned', 'hoursearned_func');
    add_shortcode( 'hoursawarded', 'servicehours_func');
    add_shortcode( 'rank', 'rank_func');
    add_shortcode( 'memstatus', 'memstatus_func');
}
add_action('init', 'register');
var_dump(hoursearned_func($user));

尝试创建一个带有属性的简码,(或)检索简码函数中的 $user 数据并将它们设置为默认值。

function example_func($atts) {
    $user = get_user_array(); //Retrieve the data
    $atts = shortcode_atts($user, $atts);
    return 'example: ' . $atts['foo'] . ' ' . $atts['bar'];
}
add_shortcode('example', 'example_func');

看看Shortcode API 基本都解释清楚了
