I have a html form which has a select list box from which you can select multiple values because its multiple property is set to multiple. Consider form method is 'GET'. The html code for the form is as follows:

<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>

I want to display the selected values in select list box on display.php page. So how are the selected values accessed on display.php page using $_GET[] array.

Are you allowed to rename select2? Or does someone else control the form? – Damian Yerrick

If you want PHP to treat $_GET['select2'] as an array of options just add square brackets to the name of the select element like this: <select name="select2[]" multiple …

Then you can acces the array in your PHP script

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

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

$_GET may be substituted by $_POST depending on the <form method="…" value.

Change:

<select name="select2" ...

To:

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

You can use this code to retrieve values from multiple select combo box

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;
}
?>

Use the following program for select the multiple values from select box.

multi.php

<?php
print <<<_HTML_
<html>
        <body>
                <form method="post" action="value.php">

    <html>

<form id="form1" name="form1" method="get" action="display.php">

      <td><label>Multiple Selection </label>&nbsp;</td>
      <td><select name="select2[]" size="3" multiple="multiple" tabindex="1">

You can iterate it directly like this

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

or you can do it like this

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

This will display the selected values:

<?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"); 
         } 
         ...

         ...
    }
?>

You could do like this too. It worked out for me.

<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>

Then take the multiple selection from following PHP code below. It print the selected multiple values accordingly.

$shift=$_POST['selectDuration'];

print_r($shift);

I fix my problem with javascript + HTML. First i check selected options and save its in a hidden field of my form:

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

Next, i get by post that field and get all the string ;-) I hope it'll be work for somebody more. Thanks to all.
