php rename function is not working - php

I have written the following Codeigniter function to rename a folder but its not working, the folder also contains 2 sub-folders and that folders contains some CSS and image files.
function _rename_theme_folder($old_name, $new_name){
echo THEMES_BASE_URL . $old_name."<br>";
echo THEMES_BASE_URL . $new_name;
rename(THEMES_BASE_URL . $old_name, THEMES_BASE_URL . $new_name);
exit;
}
Note: I can read and write files to the same directory but renaming is not working.
Output of the above function:
D:\wwwroot\ds_menu\static\front\naveed
D:\wwwroot\ds_menu\static\front\naveedkhan

PHP ftp_nlist returning false when retrieving large directory?

What I'm trying to do:
Use PHP ftp_nlist to retrieve the contents of a directory on the FTP server
The problem:
For directories that contain a lot of files (the one I encountered the problem on has nearly 40 thousand files, and no subfolders), the ftp_nlist function is returning false. For directories that are not as large, the ftp_nlist function returns an array of filenames as expected.
What I've tried:
Enabling passive mode (it already was enabled, but I see it as a common suggestion)
Adding ftp_set_option($conn_id, FTP_USEPASVADDRESS, false); after my ftp_login
using ftp_chdir, although my folder names never have spaces anyways
echoing error_get_last() after ftp_nlist returns false. The error show seems unrelated, but is shown below.
My code:
In case it is useful, here is the function I have created. What it is supposed to do is...
take in $fm (filemaker, unrelated to this problem)
take in $FTPConnectionID (the ftp connection I established in the prior to the function call)
take in $FolderPath (the path of the folder on the FTP server for which I want to list files/subfolders recursively - ex: "SomeFolder/Testing")
take in $TextFile (I am writing the paths of every file found on the FTP server to a text file, which was created prior to calling the function)
function createAuditFile($fm, $FTPConnectionID, $FolderPath, $TextFile) {
echo "createAuditFile called for " . $FolderPath . "\n";
//Get the contents of the given path. Will include files and folders.
$FolderContents = ftp_nlist($FTPConnectionID, $FolderPath);
if($FolderContents == false) {
echo "Couldn't get " . $FolderPath . "\n";
echo "ERROR: " . print_r(error_get_last()) . "\n";
} else {
print_r($FolderContents);
}
//Loop through the array, call this function recursively if a folder is found.
if(is_array($FolderContents)) {
foreach($FolderContents as $Content) {
//Create a varaible for the folder path
$ContentPath = $FolderPath . "/" . $Content;
//Call the function recursively if a folder is found
if(pathinfo($Content, PATHINFO_EXTENSION) == "") {
createAuditFile($fm, $FTPConnectionID, $ContentPath, $TextFile);
echo "Recursive call for " . $ContentPath . "\n";
//If a file is found, add the file ftp path to our array
} else {
echo "Writing to file: " . $ContentPath . "\n";
fwrite($TextFile, $ContentPath . "\n");
}
}
}
}
I can provide other code if needed, but I think my question is less of a coding issue, and more of an understanding ftp_nlist issue. I've been stuck on this for hours, so any help is appreciated. And like I said, this function works just fine for most folder paths passed to it, the problem is when there are tens of thousands of files within the folder. Thank you!

Cakephp: Show image if uploaded or show text if image was not uploaded

I am developing a system where the user may upload up to four photos. If the user does not upload a photo I would like that the follow text will be displayed: 'empty'.
I have prepared the below code however I didn't managed :/ The problem is that when an image is uploaded it still prints 'empty' and the uploaded image does not show up.
<?php if (file_exists('../files/collection/photo2/' .$collection['Collection']['photo_dir2'] . '/thumb_' . $collection['Collection']['photo2']))
{
echo $this->Html->image('../files/collection/photo2/' . $collection['Collection']['photo_dir2'] . '/thumb_' . $collection['Collection']['photo2']);}
else
{
echo ('empty');
}
?>
I appreciate you guidance and help :)
TLDR: The file you're checking for doesn't exist. Fix your path.
Detail:
You're trying to use the same path for both your HTML <img> as well as the PHP file_exists() check.
The problem is, that the HTML image is looking for a file via the user's browser, where the file_exists() method is looking for the file via your server. The two paths are very rarely the same.
Try using a correct path in your PHP's file_exists() method, and it should pass the check.
For example:
if(file_exists(APP . 'files' . DS . 'collection' . DS . 'photos2' . $collection['Collection']['photo_dir2'] . DS . 'thumb_' . $collection['Collection']['photo2'])) {
echo $this->Html->image('../files/collection/photo2/' . $collection['Collection']['photo_dir2'] . '/thumb_' . $collection['Collection']['photo2']);
}
else {
echo ('empty');
}

use file_exists() to check wordpress uploads folder

I have created a directory in Wordpress uploads folder for end user to bulk upload photos via ftp. Images are numbered 1.jpg, 2.jpg... etc. I've generated the image urls successfully, but now I want to test for empty urls - i.e. if "8.jpg" doesn't exist, show a placeholder image from the theme's images folder instead.
I'm trying to use file_exists(), but this returns false every time and always displays the placeholder image. Any suggestions would be appreciated.
<?php while ( have_posts() ) : the_post();
// create url to image in wordpress 'uploads/catalogue_images/$sale' folder
$upload_dir = wp_upload_dir();
$sub_dir = $wp_query->queried_object;
$image = get_field('file_number');
$image_url = $upload_dir['baseurl'] . "/catalogue_images/" . $sub_dir->name . "/" . $image . ".JPG"; ?>
<?php if(file_exists($image_url)){
echo '<img src="' . $image_url . '" alt="" />';
} else {
//placeholder
echo '<img src="' . get_bloginfo("template_url") . '/images/photo_unavailable.jpg" alt="" />';
} ?>
<?php endwhile; ?>
The PHP file_exists function mainly expects an internal server path to the file to be tested. This is made obvious with the example.
Fortunately, we see that wp_upload_dir() gives us several useful values:
'path' - base directory and sub directory or full path to upload directory.
'url' - base url and sub directory or absolute URL to upload directory.
'subdir' - sub directory if uploads use year/month folders option is on.
'basedir' - path without subdir.
'baseurl' - URL path without subdir.
'error' - set to false.
I've bolded what we want to use. Using these two values, you have to generate two variables, one for the external URL and one for the internal file path:
$image_relative_path = "/catalogue_images/" . $sub_dir->name . "/" . $image . ".JPG";
$image_path = $upload_dir['basedir'] . $image_relative_path;
$image_url = $upload_dir['baseurl'] . $image_relative_path;
Then use file_exists($image_path) instead of file_exists($image_url).
Note
As with the PHP notes on PHP >= 5.0.0, you can indeed use file_exists with some URLs, however the http:// protocol is not supported for the stat() function (which is what file_exists uses.)
You have to use an internal path for checking if a file exists.
So use $upload_dir['path'] instead $upload_dir['baseurl']
[path] - base directory and sub directory or full path to upload
directory.

File upload using cakephp

I just want to upload a single pdf file using cakephp,
here is my view called pdfadd.ctp:
<?php echo $this->Form->create('pdfadd1', array('enctype' => 'multipart/form-data'));?>
<fieldset>
<?php
echo $this->Form->file('Document.submittedfile');
?>
</fieldset>
<?php echo $this->Form->end(__('Submit'));?>
Here is my conroller:
public function pdfadd(){
if ($this->request->is('post') || $this->request->is('put')) {
//die();
$file = $this->request->data['Document']['submittedfile'];
//$this->pdfadd1->save($this->request->data);
move_uploaded_file($this->data['Document']['submittedfile']['tmp_name'], $_SERVER['DOCUMENT_ROOT'] . '/app/webroot/files/' . $this->data['Document']['submittedfile']['name']);
}
It gives me this error:
Warning (2): move_uploaded_file(D:/Program Files D/xampp/htdocs/app/webroot/files/Functions Package for email (1).pdf): failed to open stream: No such file or directory [APP\Controller\PagesController.php, line 29]
Warning (2): move_uploaded_file() [function.move-uploaded-file]: Unable to move 'D:\Program Files D\xampp\tmp\php862.tmp' to 'D:/Program Files D/xampp/htdocs/app/webroot/files/Functions Package for email (1).pdf' [APP\Controller\PagesController.php, line 29]
And also I want to rename the file to 1.pdf. The file should save in webroot/files.
Replace this:
$_SERVER['DOCUMENT_ROOT'] . '/app/webroot/files/' . $this->data['Document']['submittedfile']['name']
with this:
WWW_ROOT . 'files' . DS . '1.pdf'
However, you really should do more validation, like using PHP's is_uploaded_file function, making sure the file really is a PDF, etc.
move_uploaded_file($this->data['Document']['submittedfile']['tmp_name'], $_SERVER['DOCUMENT_ROOT'] . '/app/webroot/files/' . $this->data['Document']['submittedfile']['name']);
1.Change this code according to directory
2.c:xampp/htdocs(its a default location for uploading in cakephp ),then put your upload file location
move_uploaded_file($this->data['Document']['submittedfile']['tmp_name'], $_SERVER['DOCUMENT_ROOT'] . 'cakephp/app/webroot/files/' . $this->data['Document']['submittedfile']['name']);
3.You can rename it before uploading
This line get only file name, not file.
$file = $this->request->data['Document']['submittedfile'];
You could use this.
$file = $_FILES ['Document'] ['submittedfile'];

symlink directory

Can I get an eyeball on my symlink?
I'm trying to download a file from one directory, while the file actually exists in another.
I've got the actual file, and the symlink in seperate subdirectories, but both reside in the public html(both are web accessible).
I've verified the file and file location on my (shared Linux) server by going to the file directly.
The link is being created (I've used readlink, is_link, and linkinfo), and I can see it when I FTP in.
I believe I am probably just having a misunderstanding of the directory structure.
I put the file here: ./testdownload/
I put the symlink here: ./testDelivery/
<?php
$fileName = "testfiledownload.zip";//Name of File
$fileRepository = "./testdownload/";//Where the actual file lives
$downloadDirectory = "./testDelivery/";//Where the symlink lives
unlink($downloadDirectory . $fileName); // Deletes any previously exsisting symlink (required)
symlink($fileRepository . $fileName, $downloadDirectory . $fileName);
$checkLink = ($downloadDirectory . $fileName);
if (is_link($checkLink))
{
echo ("<br>Symlink reads: " .readlink($checkLink) . "<br>");
echo ("<br>LinkeInfo reads: " . linkinfo($checkLink));
}
?>
<p><a href="<?php echo ("/testDelivery/" . $fileName); ?>"</a>SymLink</p>
<p><a href="<?php echo ("/testdownload/" . $fileName); ?>"</a>regular link</p>
Everything looks right to me....but the link won't work.
Help?
Ultimately, I will put the source data outside the public area...this is just for testing.
(I'm trying to find a better solution for download than chunking out fread which fails for poor connections. (200-400MB files))
My problem (appears) to be not providing the absolute path for the symlink.
I've added the absolute path below to the same code above, to give a working copy:
<?php
$absolutepath = ( $_SERVER['DOCUMENT_ROOT']);
$fileName = "testfiledownload.zip";//Name of File
$fileRepository = "/testdownload/";//Where the actual file lives
$downloadDirectory = "/testDelivery/";//Where the symlink lives
unlink($absolutepath .$downloadDirectory . $fileName); // Deletes any previously exsisting symlink (required)
symlink($absolutepath . $fileRepository . $fileName, $absolutepath. $downloadDirectory . $fileName);
$checkLink = ($absolutepath . $downloadDirectory . $fileName);
if (is_link($checkLink))
{
echo ("<br>Symlink reads: " .readlink($checkLink) . "<br>");
echo ("<br>LinkeInfo reads: " . linkinfo($checkLink));
}
?>
<p><a href="<?php echo ("/testDelivery/" . $fileName); ?>"</a>SymLink</p>
<p><a href="<?php echo ("/testdownload/" . $fileName); ?>"</a>regular link</p>
This original post, is a duplicate (though I didn't see it until now)
Create a valid symlink for PHP file
(Most of the answers given for that question were wrong however--but the original poster figured it out, and it worked for me too)
