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>_x000D_
<head>_x000D_
<title>Untitled Document</title>_x000D_
</head>_x000D_
<body>_x000D_
<form id="form1" name="form1" method="get" action="display.php">_x000D_
<table width="300" border="1">_x000D_
<tr>_x000D_
<td><label>Multiple Selection </label> </td>_x000D_
<td><select name="select2" size="3" multiple="multiple" tabindex="1">_x000D_
<option value="11">eleven</option>_x000D_
<option value="12">twelve</option>_x000D_
<option value="13">thirette</option>_x000D_
<option value="14">fourteen</option>_x000D_
<option value="15">fifteen</option>_x000D_
<option value="16">sixteen</option>_x000D_
<option value="17">seventeen</option>_x000D_
<option value="18">eighteen</option>_x000D_
<option value="19">nineteen</option>_x000D_
<option value="20">twenty</option>_x000D_
</select>_x000D_
</td>_x000D_
</tr>_x000D_
<tr>_x000D_
<td> </td>_x000D_
<td><input type="submit" name="Submit" value="Submit" tabindex="2" /></td>_x000D_
</tr>_x000D_
</table>_x000D_
</form>_x000D_
</body>_x000D_
</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.
This question is related to
php
html
drop-down-menu
combobox
html-table
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 $a;
}
?>
This will display the selected values:
<?php
if ($_POST) {
foreach($_POST['select2'] as $selected) {
echo $selected."<br>";
}
}
?>
<html>
<head>
<title>Untitled Document</title>
</head>
<body>
<form id="form1" name="form1" method="get" action="display.php">
<table width="300" border="1">
<tr>
<td><label>Multiple Selection </label> </td>
<td><select name="select2[]" size="3" multiple="multiple" tabindex="1">
<option value="11">eleven</option>
<option value="12">twelve</option>
<option value="13">thirette</option>
<option value="14">fourteen</option>
<option value="15">fifteen</option>
<option value="16">sixteen</option>
<option value="17">seventeen</option>
<option value="18">eighteen</option>
<option value="19">nineteen</option>
<option value="20">twenty</option>
</select>
</td>
</tr>
<tr>
<td> </td>
<td><input type="submit" name="Submit" value="Submit" tabindex="2" /></td>
</tr>
</table>
</form>
</body>
</html>
You can iterate it directly like this
foreach ($_GET['select2'] as $value)
echo $value."\n";
or you can do it like this
$selectvalue=$_GET['select2'];
foreach ($selectvalue as $value)
echo $value."\n";
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.
// 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");
}
...
...
}
?>
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">
<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/>";
}
?>
Change:
<select name="select2" ...
To:
<select name="select2[]" ...
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($shift);
foreach ($_POST["select2"] as $selectedOption)
{
echo $selectedOption."\n";
}
