如何在php中获得多个选择框的选择值?

我有一个html表单，它有一个选择列表框，从中可以选择多个值，因为它的multiple属性被设置为multiple。考虑表单方法是'GET'。表单的html代码如下:

<html> <head> <title>Untitled Document</title> </head> <body> <form id="form1" name="form1" method="get" action="display.php"> <table width="300" border="1"> <tr> <td><label>Multiple Selection </label> </td> <td><select name="select2" size="3" multiple="multiple" tabindex="1"> <option value="11">eleven</option> <option value="12">twelve</option> <option value="13">thirette</option> <option value="14">fourteen</option> <option value="15">fifteen</option> <option value="16">sixteen</option> <option value="17">seventeen</option> <option value="18">eighteen</option> <option value="19">nineteen</option> <option value="20">twenty</option> </select> </td> </tr> <tr> <td> </td> <td><input type="submit" name="Submit" value="Submit" tabindex="2" /></td> </tr> </table> </form> </body> </html>

我想在display.php页面的选择列表框中显示所选值。那么如何使用$_GET[]数组访问display.php页面上的选定值呢?

当前回答

这将显示所选的值:

<?php

    if ($_POST) { 
        foreach($_POST['select2'] as $selected) {
            echo $selected."<br>";
        }
    }

?>

    <html>
<head>
<title>Untitled Document</title>
</head>
<body>
<form id="form1" name="form1" method="get" action="display.php">
  <table width="300" border="1">
    <tr>
      <td><label>Multiple Selection </label>&nbsp;</td>
      <td><select name="select2[]" size="3" multiple="multiple" tabindex="1">
        <option value="11">eleven</option>
        <option value="12">twelve</option>
        <option value="13">thirette</option>
        <option value="14">fourteen</option>
        <option value="15">fifteen</option>
        <option value="16">sixteen</option>
        <option value="17">seventeen</option>
        <option value="18">eighteen</option>
        <option value="19">nineteen</option>
        <option value="20">twenty</option>
      </select>
      </td>
    </tr>
    <tr>
      <td>&nbsp;</td>
      <td><input type="submit" name="Submit" value="Submit" tabindex="2" /></td>
    </tr>
  </table>
</form>
</body>
</html>

你可以像这样直接迭代

foreach ($_GET['select2'] as $value)
    echo $value."\n";

或者你可以这样做

$selectvalue=$_GET['select2'];
foreach ($selectvalue as $value)
    echo $value."\n";

这将显示所选的值:

<?php

    if ($_POST) { 
        foreach($_POST['select2'] as $selected) {
            echo $selected."<br>";
        }
    }

?>

// CHANGE name="select2" TO name="select2[]" THEN
<?php
  $mySelection = $_GET['select2'];

  $nSelection = count($MySelection);

  for($i=0; $i < $nSelection; $i++)
   {
      $numberVal = $MySelection[$i];

        if ($numberVal == "11"){
         echo("Eleven"); 
         }
        else if ($numberVal == "12"){
         echo("Twelve"); 
         } 
         ...

         ...
    }
?>

变化:

<select name="select2" ...

To:

<select name="select2[]" ...

如果你想让PHP将$_GET['select2']作为一个选项数组，只需在select元素的名称后添加方括号，就像这样:<select name="select2[]" multiple…

然后可以在PHP脚本中访问该数组

<?php
header("Content-Type: text/plain");

foreach ($_GET['select2'] as $selectedOption)
    echo $selectedOption."\n";

$_GET可以被$_POST替换，这取决于<form method="…"值。
