Question

我感到非常沮丧-由于某种原因，我的函数未返回任何内容。使用我的所有其他功能，它们可以正常工作。我来回传递数组，没问题。

function get_location_data ($info,$wpdb)
{
    //Status Reports Not Working- but page not broken so Fix this.
    //Location Records
    //This is more complex b/c of the way that the DB is done. 
    $data_passed = explode("++", $info["location_station_ID"]);
    //var_dump ($info);
    //echo "<br>";
    //var_dump ($data_passed);
    $location_key = trim($data_passed[0]);
    $location_name = $data_passed [1];

    //var_dump ($location_key);
    //echo '<br>';

    //Query the DB and get all the location reports for the location
    $sql = "SELECT report_key, ship_deployment_line_key FROM stations_deployed_rows WHERE station_key = '" . $location_key . "'";

    $reports_in_db = $wpdb->get_results($sql);
    $qry = $wpdb->last_query;
    //var_dump ($qry);
    //var_dump ($reports_in_db);
    if (empty($reports_in_db))
    {
        echo "No Records for location " . $location_name . "\n";
        $total_report = "None";
    }
    else
    {
        $total_report = array();
        $loop_c = 0;
        foreach($reports_in_db as $key)
        {
            ++$loop_c;
            $total_report [$loop_c] = $key;                     
        }

        //var_dump ($total_report);
        $tables_to_sort = sort_rows_into_tables ($total_report,"ship_deployment_line_key", $wpdb);      
        print_report_types ($tables_to_sort);
    }

    return $total_report;
}

基本上我想做的-从此函数中删除打印调用，而是返回要打印的行数组。

$data_passed = explode("++", $_POST ["location_station_ID"]);
$tables = get_location_data ($data_passed,$wpdb);
var_dump ($tables);

这是函数被调用的地方。

但是：当我var_dump $tables时-没有任何显示。该函数与被调用的文件位于不同的文件中（尽管这不应该成为问题-函数文件中的许多函数返回值）

关于发生的事情有什么想法吗？

PHP函数不返回任何内容
