Question

Here is the code.

<?php
$dirname = 'music';

$dir = new DirectoryIterator($dirname);

foreach ($dir as $path => $splFileInfo)
{
if ($splFileInfo->isDir())
    continue;


 $output = explode(' ', $splFileInfo, 5);
echo "<form>";
?><input type="checkbox" name="<?php echo $output[0] ?>" /><?php echo "$output[0]"; ?>
<input type="checkbox" name="<?php echo $output[1] ?>" /><?php echo "$output[1]"; ?>
<input type="checkbox" name="<?php echo $output[2] ?>" /><?php echo "$output[2]"; ?>
<?php echo "</form>";

}
?>

This causes there to be two extra checkboxes after the ones coded for. Example: image since it won’t let me post images yet.

Answer 1

I think you’re trying to do something in the loop that should be done outside it. I expected that exact output based on the code, so let me take a stab at a fix here:

<form action="" method="post">
<?php
$dirname = 'music';
$dir     = new DirectoryIterator($dirname);
foreach ($dir as $path => $splFileInfo)
{
    if ($splFileInfo->isFile())
    {
        $filename = $splFileInfo->getFilename();
        ?>
        <input type="checkbox" name="<?= $filename; ?>" /><label><?= $filename; ?></label><br />
        <?php
    }
}
?>
</form>
