Dynamic file name with multiple image upload - php

Question

I am using class.upload.php and I have the code all working except I want to extend the my script to work with multiple file uploads I read the documentation on the website and was able to figure it out. However I need my image files output like m_1234_1, m_1234_3, m_1234_4 and so on... How does one make it so that $handle->file_new_name_body = $new_name; starts with $new_name.'1' and continues adding 1 to every iteration?
<?php
$id = $_GET['id'];
if(isset($_POST['submit'])) {
// define variables
$new_name = 'm_'.$id.'_';
$thumb_name = 't_'.$id.'_';
$ext = 'jpg';
$upload_path = 'images/uploads/'.$id.'/'; // will not work with /images/
$full_src = $upload_path.$new_name.'.'.$ext;
// end define variables
$files = array();
foreach ($_FILES['userfile'] as $k => $l) {
foreach ($l as $i => $v) {
if (!array_key_exists($i, $files))
$files[$i] = array();
$files[$i][$k] = $v;
}
}
foreach ($files as $file) {
$handle = new upload($_FILES['userfile']);
if ($handle->uploaded) {
// save uploaded image 458 x 332
$handle->file_new_name_body = $new_name;
$handle->image_convert = $ext;
$handle->allowed = array('image/*');
$handle->jpeg_quality = 95;
$handle->image_resize = true;
$handle->image_ratio_crop = true;
$handle->image_x = 458;
$handle->image_y = 332;
$handle->file_overwrite = true;
$handle->auto_create_dir = true;
$handle->process($upload_path);
if ($handle->processed) {
mysql_select_db($db);
mysql_query("UPDATE projects SET last_modified=NOW(), project_image_1 = '".$full_src."' WHERE id = $id") or die(mysql_error());
} else {
echo '<div class="ec-messages messages-error">';
echo 'Error: ' . $handle->error;
echo '</div>';
}
// create thumbnail 104 x 76
$handle->file_new_name_body = $thumb_name;
$handle->image_convert = $ext;
$handle->allowed = array('image/*');
$handle->jpeg_quality = 90;
$handle->image_resize = true;
$handle->image_ratio_crop = true;
$handle->image_x = 104;
$handle->image_y = 76;
$handle->file_overwrite = true;
$handle->auto_create_dir = true;
$handle->process($upload_path);
if ($handle->processed) {
echo '<div class="ec-messages messages-success">Image successfully uploaded and added to database (thumnails created)<br>Redirecting to projects main...</div><br><img src="'.$full_src.'" class="display-image">';
echo "<script>setTimeout(\"location.href='projects.php?msg=insert';\",2000);</script>";
include('Templates/footer_exit.php');
$handle->clean();
exit;
} else {
// no error here, error will be handled by the first script
}
}
}
}
?>
UPDATED (now working):
<?php
$id = $_GET['id'];
if(isset($_POST['submit'])) {
// define variables
$ext = 'jpg';
$upload_path = 'images/uploads/'.$id.'/'; // will not work with /images/
// end define variables
$files = array();
foreach ($_FILES['userfile'] as $k => $l) {
foreach ($l as $i => $v) {
if (!array_key_exists($i, $files))
$files[$i] = array();
$files[$i][$k] = $v;
}
}
$counter = 1;
foreach ($files as $file) {
//$append = rand(100,99999);
$new_name = 'm_'.$id;
$thumb_name = 't_'.$id;
$handle = new upload($file);
if ($handle->uploaded) {
// save uploaded image 458 x 332
$count = $counter++;
$nn = sprintf("%s_%d", $new_name, $count);
$full_src = $upload_path.$nn.'.'.$ext;
$handle->file_new_name_body = $nn;
$handle->image_convert = $ext;
$handle->allowed = array('image/*');
$handle->jpeg_quality = 95;
$handle->image_resize = true;
$handle->image_ratio_crop = true;
$handle->image_x = 458;
$handle->image_y = 332;
$handle->file_overwrite = true;
$handle->auto_create_dir = true;
$handle->process($upload_path);
if ($handle->processed) {
mysql_select_db($db);
mysql_query("UPDATE projects SET last_modified=NOW(), project_image_".$count." = '".$full_src."' WHERE id = $id") or die(mysql_error());
} else {
echo '<div class="ec-messages messages-error">';
echo 'Error: ' . $handle->error;
echo '</div>';
}
// create thumbnail 104 x 76
$tn = sprintf("%s_%d", $thumb_name, $count);
$handle->file_new_name_body = $tn;
$handle->image_convert = $ext;
$handle->allowed = array('image/*');
$handle->jpeg_quality = 90;
$handle->image_resize = true;
$handle->image_ratio_crop = true;
$handle->image_x = 104;
$handle->image_y = 76;
$handle->file_overwrite = true;
$handle->auto_create_dir = true;
$handle->process($upload_path);
if ($handle->processed) {
echo 'Done!';
/*

}

}
?>

Answer 1

You might define
$new_name = 'm_'.$id.'_';
$counter = 1; // File counter
at the beginning, and replace that line with
$handle->file_new_name_body = sprintf("%s.%d", $new_name, $counter++);
so that 'file' would become 'file.1.jpg', and so on.
