Question

飞机桌上的我的选择框项目

<select name="selectaircraft">
<option id="0">-- Select Aircraft -- </option>
<?php
require("dbc.php");
$getallaircraft = mysql_query("SELECT * FROM aircrafttable");
while($viewallaircraft = mysql_fetch_array($getallaircraft)){
?>
<option id="<?php echo $viewallaircraft['ID']; ?>">
<?php echo $viewallaircraft['aircraft'] ?> </option>
<?php } ?>
</select>

大家好我试图使用selectaircraft的值来搜索并将结果显示到文本框..这是我的代码到目前为止

<?php
   require("dbc.php");
       $getallconfig = mysql_query("SELECT * FROM aircrafttable WHERE aircraft LIKE 'PR200'");  
   while($viewallconfig= mysql_fetch_array($getallconfig)){

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

正如你所看到的，我只把PR200用于搜索，我的问题是如何使用select值代替？我还希望每次单击选择框时都会发生搜索查询。

伙计们可以帮助我吗？我知道如何在VB6中编写代码，就像这样

假设：选择名称或在VB6中使用combobox = selectbox

Private Sub Combo3_Click()
adodc1.recorsource ="Select * from aircrafttable where aircraft = " & selectbox & "'"
adodc1.refresh


Text1.Text = Adodc1.Recordset("aircraft")

每次点击combo / selectbox时，查询都会执行并给文本框提供不同的答案。我不知道如何在PHP中执行此操作帮助！

已编辑添加了所有代码

Answer 1

试试这样;

$aircraft = mysql_real_escape_string($_POST['selectaircraft']);  //or $_GET

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

Answer 2

您可以将选择框（第1个）保留在表单中，在更改时将表单提交到下一页。

获取POST / GET值，并将其用于选择查询以进行搜索。

Answer 3

触发提交更改选择框如下

<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>

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 } 
}?>

更新更新的代码以维护选择框的状态。

PHP使用选择值搜索并将结果显示到文本框
