Wordpress Shortcode not passing variable from function (Newbie) - php

Question

Here is the snippet of code in question:
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');
This small function simply returns the value of an array given the key, but when calling the shortcode, [hoursearned], it only displays:
Service Hours Earned: Hours
rather than:
Service Hours Earned: 200 Hours
Where 200 is a string that is returned by the function hoursearned_func given $user.
For some reason Wordpress is not passing the returned variables from the functions to the shortcodes. How can I get Wordpress to show the result from the function?
Here is the full code if that helps... (note that all of this is being loaded as a plugin)
//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));

Answer 1

Try to create a shortcode with attributes, (or) retrieve the $user data inside the shortcode's function and set them as default values.
function example_func($atts) {
$user = get_user_array(); //Retrieve the data
$atts = shortcode_atts($user, $atts);
return 'example: ' . $atts['foo'] . ' ' . $atts['bar'];
}
add_shortcode('example', 'example_func');
Have a look at the Shortcode API it basically explains everything.
