Question

我设置了搜索功能。当我输入关键字时，我得不到任何记录，也没有错误信息。只是表头。我在数据库中看到了其他部门。当我在关键字框中输入它时，我什么都没有回来。

<html>
<head>
<title></title>
</head>
<body>
<form name="frmSearch" method="get" action="">
  <table width="599" border="1">
    <tr>
      <th>Keyword
      <input name="txtKeyword" type="text" id="txtKeyword" value="<?php echo $_GET["txtKeyword"];?>">
      <input type="submit" value="Search"></th>
    </tr>
  </table>
</form>
<?php
if($_GET["txtKeyword"] != "")
    {
        $serverName = "localhost";
    $objConnect = new PDO( "sqlsrv:server=$serverName ; Database=maintenance", "TestUser", "test") or die("Error Connect to Database");

    // Search By lanId or department
    $objQuery = $objConnect->prepare("SELECT  * FROM requests  WHERE (lanId LIKE '%".$_GET["txtKeyword"]."%' or department LIKE '%".$_GET["txtKeyword"]."%' )  ");

    ?>
    <table width="600" border="1">
      <tr>
        <th width="91"> <div align="center">lanId </div></th>
        <th width="98"> <div align="center">Name </div></th>
        <th width="198"> <div align="center">department </div></th>

      </tr>
    <?php

        while( $objResult = $objQuery->fetch(PDO::FETCH_ASSOC))
    {
    ?>
      <tr>
        <td><div align="center"><?php echo $objResult["lanId"];?></div></td>
        <td><?php echo $objResult["name"];?></td>
        <td><?php echo $objResult["department"];?></td>

    <?php
    }
    ?>
    </table>
    <?php

}
?>
</body>
</html>

使用prepare()语句时，您还应使用execute()： http://coursesweb.net/php-mysql/pdo-prepare-execute

在搜索框中键入关键字时未提取数据
