Multiple Html Select

iugin

Hi,

I try to get the values selected from a multiple select but I get only the last value. Here is an example:

==========file1.php==============

<?php

echo '<form method="post" action="file2.php">
<select name=number multiple size=5>';

for ($i=0;$i<10;$i++) {
echo "<option value=".$i.">".$i."</option>";
}
echo '</select>
<input type="submit" name="submit" value="Please">
</form>';

==========file2.php================

<?php

echo $number;
?>

Now, if the user select let's say 2 and 3 the file2.php will print 3 and this is not OK.

Could anyone help me with this?

You have to make your select name be an array by using brackets after the name

Then to access the array, you have access to an array variable called $whatever, or if register globals is set to off $_POST['whatever']

you can use a foreach loop to loop through the values.

First thanks for the prompt answaer. I looked again at foreach but I didn't figured out how this will help me, because I have only the last value.

I try to made some test but all got wrong. Some example code will help if this is not to much, untill then I will try myself

Thanks again

<form method="post" action="process.php">

<select name="numbers[]" multiple>

<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
<option value="4">Four</option>
<option value="5">Five</option>

</select><br><br>

<input type="submit" value="Submit">

</form>

-- process.php --

foreach($_POST['numbers'] as $value) {
   echo $value . "<br>";
}

Process.php merely gets the selected values, then echo's them each on their own line. You should be able to understand the basic concept now and modify the code to suit your needs.

If I use your syntax I get an error:

Warning: Invalid argument supplied for foreach()

I think this is it because php don't know that I send an table.

I changed a little the process.php and now it work. Thanks again for your help. I put the changes here maybe somwone will use it sometimes.

<?php

//foreach($_POST['numbers'] as $value) {
foreach($numbers as $value) {
echo $value . "<br>";
}
?>

well you have register globals set to on, that's why you can access the variable as $numbers instead of $_POST['numbers']

The invalid argument may just be that instead of $_POST, you need to use $HTTP_POST_VARS due to an older version of PHP, but since you have register globals set to on, you don't need to worry about that.
