Delete images from two directories - php

Question

I have a script that loads images in the database and in two directories: uploads / original and a directory for the preview: uploads / thumbs
I need to create a small panel to delete inserted images, I have already created the code to delete from the database, but I can not delete them from the two directories.
I know I need to use unlink, but I'm no expert, I do not know where to place the code etc. I ask for help to you.
This is the file that I delete.php structured so far:
<?php
$con = mysql_connect("localhost","*******","******");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("**********************", $con);
if($_POST)
{
$ids = isset($_POST['id']) ? $_POST['id'] : array();
elimina_record($ids);
}
elseif(isset($_GET['id']))
{
elimina_record(array($_GET['id']));
}
else
mostra_lista();
function mostra_lista()
{
// mostro un eventuale messaggio
if(isset($_GET['msg']))
echo '<b>'.htmlentities($_GET['msg']).'</b><br /><br />';
// preparo la query
$query = "SELECT id,name,filename FROM image";
// invio la query
$result = mysql_query($query);
// controllo l'esito
if (!$result) {
die("Errore nella query $query: " . mysql_error());
}
echo '
<form name="form1" method="post" action="">
<table border="1">
<tr>
<th> </th>
<th>ID</th>
<th> </th>
</tr>';
while ($row = mysql_fetch_assoc($result))
{
$name = htmlentities($row['name']);
$id = htmlentities($row['id']);
$filename = htmlentities($row['filename']);
// preparo il link per la modifica dei dati del record
$link = $_SERVER['PHP_SELF'].'?id=' . $row['id'];
echo "<tr>
<td><input name=\"id[]\" type=\"checkbox\" value=\"$row[id]\" /></td>
<td>$id</td>
<td>delete</td>
</tr>";
}
echo '</table>
<br />
<input type="submit" name="Submit" value="Elimina record selezionati" />
</form>';
// libero la memoria di PHP occupata dai record estratti con la SELECT
mysql_free_result($result);
// chiudo la connessione a MySQL
mysql_close();
}
function elimina_record($ids)
{
// verifico che almeno un id sia stato selezionato
if(count($ids) < 1)
{
$messaggio = urlencode("Nessun record selezionato!");
header('location: '.$_SERVER['PHP_SELF'].'?msg='.$messaggio);
exit;
}
// per precauzione converto gli ID in interi
$ids = array_map('intval',$ids);
// creo una lista di ID per la query
$ids = implode(',',$ids);
// preparo la query
$query = "DELETE FROM image WHERE id IN ($ids)";
// invio la query
$result = mysql_query($query);
// controllo l'esito
if (!$result) {
die("Errore nella query $query: " . mysql_error());
}
// conto il numero di record cancellati
$num_record = mysql_affected_rows();
// chiudo la connessione a MySQL
mysql_close();
$messaggio = urlencode("Numero record cancellati: $num_record");
header('location: '.$_SERVER['PHP_SELF'].'?msg='.$messaggio);
}
?>
While, it may be useful, even paste the file to upload.php files:
session_start();
$_SESSION['id']="1";
$id=$_SESSION['id'];
include 'config.php'; //assume you have connected to database already.
$folder = 'uploads/';
$name = date('YmdHis');
$filename = md5($_SERVER['REMOTE_ADDR'].rand()).'.jpg';
$original = $folder.$filename;
// The JPEG snapshot is sent as raw input:
$input = file_get_contents('php://input');
if(md5($input) == '7d4df9cc423720b7f1f3d672b89362be'){
// Blank image. We don't need this one.
exit;
}
$result = file_put_contents($original, $input);
if (!$result) {
echo '{
"error" : 1,
"message" : "Failed save the image. Make sure you chmod the uploads folder and its subfolders to 777."
}';
exit;
}
$info = getimagesize($original);
if($info['mime'] != 'image/jpeg'){
unlink($original);
exit;
}
// Moving the temporary file to the originals folder:
rename($original,'uploads/original/'.$filename);
$original = 'uploads/original/'.$filename;
// Using the GD library to resize
// the image into a thumbnail:
$origImage = imagecreatefromjpeg($original);
$newImage = imagecreatetruecolor(154,110);
imagecopyresampled($newImage,$origImage,0,0,0,0,154,110,520,370);
imagejpeg($newImage,'uploads/thumbs/'.$filename);
echo '{"status":1,"message":"Success!","filename":"'.$filename.'"}';
$sql="INSERT INTO image VALUES ('','$name','$filename')";
$result=mysqli_query($con,$sql);
$value=mysqli_insert_id($con);
$_SESSION["myvalue"]=$value;

Answer 1

$cart_1="/uploads/original/";
$cart_2="/uploads/thumbs/";
foreach($files as $file){
$f_1=$cart_1.$file;
$f_2=$cart_2.$file;
unlink($f_1);
unlink($f_2);
}

Answer 2

Check this out:
$dir1 = '/upload/original/';
$dir2 = '/upload/thumbs/';
$image = 'abc.jpg';
if(file_exists($dir1.$image))
unlink($dir1.$image);
if(file_exists($dir2.$image))
unlink($dir2.$image);
