我的Selectbox项目来自飞机表

<select name="selectaircraft">

<?php
require("dbc.php");
$getallaircraft = mysql_query("SELECT * FROM aircrafttable");

每次我单击combo/selectbox，查询都会执行，并对textbox给出不同的答案。我不知道如何在PHP中做到这一点，请帮助

编辑并添加了所有代码

像这样尝试
$aircraft = mysql_real_escape_string($_POST['selectaircraft']);  //or $_GET

$getallconfig = mysql_query("SELECT * FROM aircrafttable WHERE aircraft LIKE '".$aircraft."'");

您可以将选择框（第一个）保留在表单中，在更改时将表单提交到下一页
并获取POST/get值，并将其用于select查询以进行搜索。
在更改选择框时触发提交，如下所示
<form action="path/to/your/query/file.php" method="post"> //if query in same page leave your action blank
   <select name="selectaircraft" onchange="this.form.submi();">
     <option id="0">-- Select Aircraft -- </option>
<?php
      require("dbc.php");
      $selected_aircraft=isset($_POST['selectaircraft'])?$_POST['selectaircraft']:"";
      $getallaircraft = mysql_query("SELECT * FROM aircrafttable");
      while($viewallaircraft = mysql_fetch_array($getallaircraft)){
      $selectstr="";
      if($selected_aircraft==$viewallaircraft['aircraft'] ){
         $selectstr="selected='selected'";
      }

?>
      <option id="<?php echo $viewallaircraft['ID']; ?>" <?php echo $selectstr ?> >
<?php 
             echo $viewallaircraft['aircraft'] ?> </option>
<?php } ?>
    </select>
</form>

//如果在同一页中查询，请将操作留空
--选择飞机--

并按以下方式更改您的查询：
 <?php
        require("dbc.php");
        if(isset($_POST)){
        $selectaircraft = mysql_real_escape_string($_POST['selectaircraft']);     
         $getallconfig = mysql_query("SELECT * FROM aircrafttable WHERE aircraft LIKE '{ $selectaircraft}'"); 
 while($viewallconfig= mysql_fetch_array($getallconfig)){

?>
   <input type="text" name="aconfig "value="<?php echo $viewallconfig['config'];      ?>" />
<?php } 
}?>

您好，我希望每次单击selecbox时都能执行搜索查询。有可能吗？你想在选择框的onchange中刷新结果吗？我实际上希望在选择飞机时配置结果是自动的。您好，事实上我不知道如何在更改时输入代码：（我把这个放在哪里？谢谢。但我不想每次更改选择框时都提交我的表单。我只想自动为我的配置文本框赋值。它来自于我选择的飞机的配置。嗨，它可以工作，但选择框每次单击时都返回到---select airpairs---t为了维护选择框的状态，我添加了我所有的代码。正如你所看到的，当用户填写一些字段并单击带有查询的选择框时，我有很多字段。表单。提交所有文本字段将是清晰的，看起来很刷新。你有什么解决方法吗？非常感谢！
