Question

我正在开发一个插件，现在我想更新我的表记录....我正在使用此代码从数据库中获取数据

  <?php
    $id = $_GET\['id'\];
    $dirname = dirname(__FILE__);
    $root = false !== mb_strpos( $dirname, 'wp-content' ) ? mb_substr( $dirname, 0, mb_strpos( $dirname, 'wp-content' ) ) : $dirname;
    require_once( $root . "wp-load.php" );

        global $wpdb;
         $post_name_table = $wpdb->prefix . "tropix_dmin";
         $query = "
            SELECT post_name1, id
            FROM $post_name_table
            WHERE id= $id";
        $post_name1_results = $wpdb->get_results($query);   
    ?>    
      <table class="widefat" style="border-radius:4px;">
      <tr>
        <th class="manage-column" scope="col" style="font-weight:bold; font-size:20px;">Field</th>
        <th class="manage-column" scope="col" style="font-weight:bold; font-size:20px;">Value</th>
      </tr>
      <?php foreach ( $post_name1_results as $post_names ) {        
        $this_data = unserialize($post_names->post_name1);
        //echo "<pre>";
        //print_r($this_data);      
        if($this_data != ""){    
       ?>
      <tr class="alternate iedit">
        <td class="column-columnname">Street Address</td>
        <td class="column-columnname"><input type="text" value="<?php echo $this_data\['$Street_Address'\]; ?>"  /></td>
      </tr>
 <?php }
  } ?>
    </table>

如果要更新列，则查询应为：

   $query = "UPDATE (*table*) SET (*column to update*) = '*value*' WHERE id= $id";

要回显现有列，请使用：

$this->db_connection = new mysqli(DB_HOST, DB_USER, DB_PASS, DB_NAME);
$query = mysqli_query($this->db_connection,"SELECT *column* FROM *table* WHERE id='*your id*'");
$value = mysqli_fetch_all($query,MYSQLI_ASSOC);
echo $value[0]['column name'];

尽管注意SQL注入。
