Passing information via _POST

[moe]

Hi Guys;

 

I have successfully created a drop down listing script via the following:

 

<?php

$squidguard_dir = '/var/lib/squidguard/db/';

if ($handle = opendir($squidguard_dir)) {

?>
         <form action="<?=$PHP_SELF?>" method="POST">
         <select name="directory_name" size="1">

<?php
    while (false !== ($file = readdir($handle))) {
                if ($file != "." && $file != "..") {

            echo "<option name=$file>$file</option>";

                    }
    }
?>
    </select>

         <input type="submit">
<?php
    closedir($handle);
}

 

Now when I pass that information using the _POST function to the following:

 

<?php
if ($_POST['directory_name']) {

?>
<textarea rows=4 cols=40>
<?php
echo $directory_name;
echo $file;
}

 

I am unable to get anything displayed in the textarea, its blank.

 

I am trying to get it to echo first to make sure it is working and passing on the correct variables.

 

Any help again would be appreciated

 

Thanks Moe

please post the output of

 

<?php

print "<pre>";
print_r($_POST);

?>

You need to echo the value in the $_POST array:

<?php
if ($_POST['directory_name']) {
echo '<textarea name="somename" rows=4 cols=40>';
echo $_POST['directory_name'];
echo $_POST['file'];
echo '</textarea>';
}
?>
