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>&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>

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?


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。


变化:

<select name="select2" ...

To:

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

使用下面的程序从选择框中选择多个值。

multi.php

<?php
print <<<_HTML_
<html>
        <body>
                <form method="post" action="value.php">
                        <select name="flower[ ]" multiple>
                                <option value="flower">FLOWER</option>
                                <option value="rose">ROSE</option>
                                <option value="lilly">LILLY</option>
                                <option value="jasmine">JASMINE</option>
                                <option value="lotus">LOTUS</option>
                                <option value="tulips">TULIPS</option>
                        </select>
                        <input type="submit" name="submit" value=Submit>
                </form>
        </body>
</html>
_HTML_

?>

value.php

<?php
foreach ($_POST['flower'] as $names)
{
        print "You are selected $names<br/>";
}

?>

您可以使用此代码从多个选择组合框中检索值

HTML:

<form action="c3.php" method="post">
  <select name="ary[]" multiple="multiple">
    <option value="Option 1" >Option 1</option>
    <option value="Option 2">Option 2</option>
    <option value="Option 3">Option 3</option>
    <option value="Option 4">Option 4</option>
    <option value="Option 5">Option 5</option>
  </select>
  <input type="submit">
</form>

PHP:

<?php
$values = $_POST['ary'];

foreach ($values as $a){
    echo $a;
}
?>

这将显示所选的值:

<?php

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

?>

我用javascript + HTML解决了我的问题。首先,我检查所选的选项,并将其保存在我的窗体的隐藏字段:

for(i=0; i < form.select.options.length; i++)
   if (form.select.options[i].selected)
    form.hidden.value += form.select.options[i].value;

接下来,我得到的post字段,并获得所有的字符串;-) 我希望这是给别人的工作。谢谢大家。


// 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"); 
         } 
         ...

         ...
    }
?>

foreach ($_POST["select2"] as $selectedOption)
{    
    echo $selectedOption."\n";  
}

    <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"; 

你也可以这样做。这对我来说很有效。

<form action="ResultsDulith.php" id="intermediate" name="inputMachine[]" multiple="multiple" method="post">
    <select id="selectDuration" name="selectDuration[]" multiple="multiple"> 
        <option value="1 WEEK" >Last 1 Week</option>
        <option value="2 WEEK" >Last 2 Week </option>
        <option value="3 WEEK" >Last 3 Week</option>
         <option value="4 WEEK" >Last 4 Week</option>
          <option value="5 WEEK" >Last 5 Week</option>
           <option value="6 WEEK" >Last 6 Week</option>
    </select>
     <input type="submit"/> 
</form>

然后从下面的PHP代码中选择多个选项。它相应地打印所选的多个值。

$shift=$_POST['selectDuration'];

print_r($shift);

使用enctype="multipart/ Form -data"提交表单
