Hey guys, I have my ScreenSnpr setup, I want to setup a Cron to auto delete images after 24 hrs

From what I understand this is the basic code

    find /directory -maxdepth 1 -type f -mtime +7 -exec rm -f {} \;

But I want to be able to delete the images with an exception to the index.php file

Example the screensnpr is index.php file is
You must login or register to view this content.
or
/public_html/snpr/images

whatever you prefer.

Or maybe just a PHP script with a purge button.

I mean I made a code for that but I can't get it to work...

HTML=

    <select name="dtime">

     <option selected="selected"></option>

     <option value="1">1 minute</option>

     <option value="5">5 minutes</option>

     <option value="10">10 minutes</option>

     <option value="15">15 minutes</option>

     <option value="20">20 minutes</option>

     <option value="25">25 minutes</option>

     <option value="30">30 minutes</option>

     <option value="60">1 hour</option>

     <option value="300">5 hours</option>

     <option value="720">12 hours</option>

     <option value="1440">1 day</option>

</select>

Php would be=

    function deleteImage($time, $img)

{

    if ($time != 0 || !empty($time))

    {

        $expiretime = $time;



        $FileCreationTime = filectime($img);

        $FileAge = time() - $FileCreationTime;



        if ($FileAge > ($expiretime * 60))

        {

            unlink($img);

        }

    }

}

so Usage would be=

    $deletetime = (!empty($_POST['dtime'])) ? $_POST['dtime'] : 0;

$image  =  'i/' . $filename;



// Delete image

deleteImage($deletetime, $image);

But like I said, It does not work and there is no exception..

Help anyone?!?

Thanks

Fixed code

Place this in a folder before your images, EX
/public_html/snpr/images is where your index.php file is and /public_html/snpr/images/image is where your images are.

    <?php

     

    define('PATH', 'image/';

     

    function destroy($dir) {

        $mydir = opendir($dir);

        while(false !== ($file = readdir($mydir))) {

            if($file != "." && $file != "..") {

                chmod($dir.$file, 0777);

                if(is_dir($dir.$file)) {

                    chdir('.';

                    destroy($dir.$file.'/';

                    rmdir($dir.$file) or DIE("couldn't delete $dir$file<br />");

                }

                else

                    unlink($dir.$file) or DIE("couldn't delete $dir$file<br />");

            }

        }

        closedir($mydir);

    }

    destroy(PATH);

    echo 'all done.'; 







?>

You can just go to the URL to execute the script
or the crone code

    wget https://location.com/where/your/file/is.php >/dev/null 2>&1

This is the php for the snpr itself.

    <?php

$img = "https://YOUR-SITE/snpr/images/image/".$_GET["img"];

?>

<?php

if($img=="") { echo ""; } else { echo "<img src='" . $img . "' border=10 />" ; } ?>

If you need any help Just QUOTE me. Also, A special thanks to Alfa for helping me with the screensnpr error.

make the images save inside another folder where only the images are located then link it to that directory

Can't do that, the images have to be in the same folder as the PHP file for the snpr to work

Gotz it, Forgot to name the parent directory Smile

So if the images are in

    /public_html/snpr/images/image

and the file is in

    /public_html/snpr/images

I need to put

    find /public_html/snpr/images/image -maxdepth 1 -type f -mtime +7 -exec rm -f {} \;

right? And where would I change the time...

I know shit about Cron lol
