delete file. just a little more complex!

nokicky

Ok, i'm writing a script that shows the contents of a directory in your web browser in a styled way...
it works great but i've come across a hurdle. not sure if i'm just being really stupid or it's actually quite hard!

I want to be able to delete files with a tick box and delete button.

This is the bit of the script which creates a list of files in the directory.

<div><a href="<?=$fileurl;?>" class="<?=$class;?>"<?=$thumb2;?>><img src="scriptfiles/icons/<?=$icon;?>" alt="<?=$files[$i];?>" /><strong><?=$filename;?></strong> <em><?=round(filesize($leadon.$files[$i])/1024);?>KB</em> <?=date ("M d Y h:i:s A", filemtime($leadon.$files[$i]));?><?=$thumb;?></a></div>

I've been struggling with this for a while so any help would be really really appreciated. Thanks you in advanced.

Add the checkbox element and give it a name of "delete[]" (including the square brackets). Then the value for each one would be it's respective file-name.

<input type="checkbox" name="delete[]" value="<?php echo $filename ?>">

Then, in your script all you have to do is check to see if "delete" was set, and if it is, then loop through it and delete the appropriate files:

if(isset($_POST['delete']) && !empty($_POST['delete']))
{
    foreach($_POST['delete'] as $file)
    {
        echo 'Deleting file [' . $file . '] ... ';
        unlink('/path/to/the/'.$file);
        echo 'Done!<br />';
    }
}

Now, you'd have to do error-checking for bad "unlink" operations. Also, if the php server doesn't have the rights to the file to delete it, then unlink won't work. So you have to be careful about that too.

Thank you so much, that's a huge help.

Don't forget to mark this thread resolved (if it is).

ok so i've put in what you said.

this line works great and returns the individual file names...

<input type="checkbox" name="delete[]" value="<?php echo $filename ?>">

but i think i'm using this wrong...

    <?
    if(isset($_POST['delete']) && !empty($_POST['delete']))
{
    foreach($_POST['delete'] as $file)
    {
        echo 'Deleting file [' . $file . '] ... ';
        unlink('.'.$file);
        echo 'Done!<br />';
    }
} 
    ?>

does anything else need to be added anywhere in the script? thanks again

Not really... except that $file should have "./" before it if it's in the same directory, not "."... otherwise the files won't be deleted.
