Question

我试图将存储在数组中的信息更新到数据库中。我似乎无法让它发挥作用。任何帮助将不胜感激。感谢。

在配置类中：

function update_cfg(array $upd)
{
    if(is_array($upd))
    {
        $sql = array();
        foreach($upd as $column => $info)
        {
            if(isset($info) && $column != 'update_cfg')
            {
              $sql[] = "`" . $column . "`='" . $info . "'";
            }
        }
        if(is_array($sql))
        {
            $result = $this->Sys->db->query("UPDATE `dj_settings` SET " . implode(', ', $sql));
            if($result)
            {
                unset($sql);
                return TRUE;
            }
            else
            {
                unset($sql);
                return FALSE;
            }
        }
    }
}

脚本：

<?php
global $Sys;

if(isset($_POST['update_cfg']))
{
    unset($_POST['update_cfg']);
    $update = $_POST;
    unset($_POST);
    if($Sys->Config->update_cfg($update))
    {
      $Sys->Template->setAlerts('The website has been successfully updated!');
    }
    else
    {
      $Sys->Template->setAlerts('The website has not been updated.', 'error');
    }
    unset($update);
}

?>
<div id="webCfg">
<h2>Website Configuration</h2>
  <?php

    global $Sys;
    global $handle;

    $alerts = $Sys->Template->getAlerts();
    if ($alerts != '') { echo '<div><ul class="alerts">' . $alerts . '</ul></div>'; }
    asort($handle);
    if($handle['status'] == 1)
    {
        $enable = 'checked="checked"';
    }
    else
    {
        $disable = 'checked="checked"';
    }
    foreach ($handle as $key => $val) 
    {
      $label = str_replace('_', ' ', $key);
      if(strlen($val) <= 50 && !is_numeric($val))
      {
        $input[$key] = '<tr><td class="label"><label for="' . $key . '">' . ucwords($label) . '</label></td><td class="content"><input type="text" id="' . $key . '" name="' . $key . '" value="' . $val . '"/></td></tr>';
      }
      elseif(strlen($val) >= 51 && !is_numeric($val))
      {
        $input[$key] = '<tr><td class="label"><label for="' . $key . '">' . ucwords($label) . '</label></td><td class="content"><textarea id="' . $key . '" name="' . $key . '">' . ucfirst($val) . '</textarea></td></tr>';
      }
      elseif(is_numeric($val))
      {
        $input[$key] = '<tr><td class="label"><label for="' . $key . '">Website Status</label></td><td class="content"><input type="radio" id="' . $key . '" name="' . $key . '" value="1" ' . $enable . '> Enable  <input type="radio" id="' . $key . '" name="' . $key . '" value="0" ' . $disable . '> Disable </td></tr>';
      }
    }
  ?>
  <form action="" method="post">
  <table cellpadding="1" cellspacing="0" id="webCfgTbl">
    <?php
      foreach (array_keys($input) as $key) 
      {
        echo '<div class="row">' . $input[$key] . '</div>';
      }
    ?>
    <tr><td class="label"><label for="submit"></label></td><td class="content"><div class="row submitrow"><input type="submit" id="submit" name="update_cfg" class="submit" value="Update Settings" /></div></td></tr>
  </table>
  </form>     
</div>

?>

页面加载数据库中的信息。当我更改值并单击“更新设置”时，$Sys->Config->update_cfg()每次都会返回FALSE。我对此感到困惑，并希望得到任何帮助。感谢。

修改

当我在foreach（）循环之后在update_cfg（）函数中回显查询时，我得到了这个：

Answer 1

嗯......这是一个开始我猜...至少更新正在发挥作用。首先尝试$info = $this->Sys->db->real_escape_string($info);然后将其放入"" . $column . "='" . $info . "'";

UPDATE不使用数组
