Question

以下是相关代码片段：

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');

这个小函数只返回给定键的数组的值，但是当调用短代码[hoursearned]时，它只显示：

Service Hours Earned: Hours

而不是：

Service Hours Earned: 200 Hours

其中200是由给定$ user的函数hoursearned_func返回的字符串。

由于某种原因，Wordpress没有将返回的变量从函数传递给短代码。如何让Wordpress显示函数的结果？

    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;

尝试使用属性创建短代码，（或）检索短代码函数中的$user数据并将其设置为默认值。

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它基本上解释了一切。
