Question

我想在插件文件中使用wpdb，但出于某种原因，我没有得到错误，只是没有结果。

我只是想获得从表中的一些信息，并显示给最终用户的任何想法，为什么它不工作

function show_forminfo(){ 
    global $wpdb; 
    $sql = "SELECT * FROM 4hSIc_pods_player_ranking WHERE player_id='".$playerId."'"; 
    $clientRow = $wpdb->get_row($wpdb->prepare($sql)); 
    echo $clientRow->points_to_redeem; 
     echo "<div id='infopoints' class='modal fade' tabindex='-1' role='dialog' aria-labelledby='myModalLabel' aria-hidden='true'>"; 
     echo "<div class='modal-dialog'>"; 
     echo "<div class='modal-content'>"; 
     echo "<div class='modal-header'>"; 
     echo "<button type='button' class='close' data-dismiss='modal' aria-hidden='true'>×</button>"; 
     echo "<h4 class='modal-title'>Redeem Points</h4>"; 
     echo "</div>"; 
     echo "<form class='form-horizontal' class='contact' name='redemmpointsForm' id='redemmpointsForm' >"; 
     echo " <div class='form-group'>"; 
     echo "<h3>You have points pending:<br />"; 
     echo "".$clientRow->points_to_redeem; 
     echo "<input type='hidden' name='playerid' value='<?php echo $playerId;;?>' />"; 
     echo "  </div>"; 
     echo " <div class='form-group'>"; 
     echo "   <div class='col-md-6'>"; 
     echo "  <a href='#' class='btn btn-info' data-dismiss='modal'>Close</a>"; 
     echo "   </div>"; 
     echo "  </div>"; 
     echo "</form>"; 
     echo "  </div>"; 
     echo "  </div>"; 
     echo "  </div>"; 

    }

您需要包括WP-load.php

require('/path/to/wp-load.php');
