I cannot google anywhere that one cannot use absolute path in copy() destination. However,
$baseUrl_master_MM = "http://mysite.öä/MM/";
$img_dir = 'img_1';
$img = '01.jpg';
$orig_online = $baseUrl_master_MM.$img_dir.'/'.$img;
$dest_online = '../../mm_img/'.$img_dir.'-online.jpg';
$copy = copy($orig_preview, $dest_preview);
works fine, but the same with absolute path
$baseUrl_master_MM = "http://mysite.öä/MM/";
$baseUrl_master_MM_online = "http://mysite.öä/mm_img/";
$img_dir = 'img_1';
$img = '01.jpg';
$orig_online = $baseUrl_master_MM.$img_dir.'/'.$img;
$dest_online = $baseUrl_master_MM_online.$img_dir.'-online.jpg';
$copy = copy($orig_preview, $dest_preview);
will give no errors and copies no files.
Destination directory exists, and rights are 777. Am I missing something?
You can't use the HTTP protocol to copy a file on a server. Taken from the PHP documentation on HTTP wrapper
Allows read-only access to files/resources via HTTP 1.0, using the HTTP GET method.
To copy to your local server, use an absolute path.
Please do the following :
if(!#copy($orig_preview, $dest_preview))
{
$errors= error_get_last();
echo "COPY ERROR: ".$errors['type'];
echo "<br />\n".$errors['message'];
} else {
echo "File copied from remote!";
}
Tell what the error's you see?
Also absolute path should look like :
$abs = $_SERVER['PHP_SELF'];

I am uploading files to a server using php and while the move_uploaded_file function returns no errors, the file is not in the destination folder. As you can see I am using the exact path from root, and the files being uploaded are lower than the max size.
$target = "/data/array1/users/ultimate/public_html/Uploads/2010/";
//Write the info to the bioHold xml file.
$xml = new DOMDocument();
$xml->load('bioHold.xml');
$xml->formatOutput = true;
$root = $xml->firstChild;
$player = $xml->createElement("player");
$image = $xml->createElement("image");
$image->setAttribute("loc", $target.basename($_FILES['image']['name']));
$player->appendChild($image);
$name = $xml->createElement("name", $_POST['name']);
$player->appendChild($name);
$number = $xml->createElement("number", $_POST['number']);
$player->appendChild($number);
$ghettoYear = $xml->createElement("ghettoYear", $_POST['ghetto']);
$player->appendChild($ghettoYear);
$schoolYear = $xml->createElement("schoolYear", $_POST['school']);
$player->appendChild($schoolYear);
$bio = $xml->createElement("bio", $_POST['bio']);
$player->appendChild($bio);
$root->appendChild($player);
$xml->save("bioHold.xml");
//Save the image to the server.
$target = $target.basename($_FILES['image']['name']);
if(is_uploaded_file($_FILES['image']['tmp_name']))
echo 'It is a file <br />';
if(!(move_uploaded_file($_FILES['image']['tmp_name'], $target))) {
echo $_FILES['image']['error']."<br />";
}
else {
echo $_FILES['image']['error']."<br />";
echo $target;
}
Any help is appreciated.

Most like this is a permissions issue. I'm going to assume you don't have any kind of direct shell access to check this stuff directly, so here's how to do it from within the script:
Check if the $target directory exists:
$target = '/data/etc....';
if (!is_dir($target)) {
die("Directory $target is not a directory");
}
Check if it's writeable:
if (!is_writable($target)) {
die("Directory $target is not writeable");
}
Check if the full target filename exists/is writable - maybe it exists but can't be overwritten:
$target = $target . basename($_FILES['image']['name']);
if (!is_writeable($target)) {
die("File $target isn't writeable");
}
Beyond that:
if(!(move_uploaded_file($_FILES['image']['tmp_name'], $target))) {
echo $_FILES['image']['error']."<br />";
}
Echoing out the error parameter here is of no use, it refers purely to the upload process. If the file was uploaded correctly, but could not be moved, this will still only echo out a 0 (e.g. the UPLOAD_ERR_OK constant). The proper way of checking for errors goes something like this:
if ($_FILES['images']['error'] === UPLOAD_ERR_OK) {
// file was properly uploaded
if (!is_uploaded_File(...)) {
die("Something done goofed - not uploaded file");
}
if (!move_uploaded_file(...)) {
echo "Couldn't move file, possible diagnostic information:"
print_r(error_get_last());
die();
}
} else {
die("Upload failed with error {$_FILES['images']['error']}");
}
You need to make sure that whoever is hosting your pages has the settings configured to allow you to upload and move files. Most will disable these functions as it's a sercurity risk.
Just email them and ask whether they are enabled.
Hope this helps.
your calls to is_uploaded_file and move_uploaded_file vary. for is_uploaded_file you are checking the 'name' and for move_uploaded_file you are passing in 'tmp_name'. try changing your call to move_uploaded_file to use 'name'
I need to look for and echo an image file name that's located in either of these two directories named 'photoA' or 'photoB'.
This is the code I started with that tries to crawl through these directories, looking for the specified file:
$file = 'image.jpg';
$dir = array(
"http://www.mydomain.com/images/photosA/",
"http://www.mydomain.com/images/photosB/"
);
foreach( $dir as $d ){
if( file_exists( $d . $file )) {
echo $d . $file;
} else {
echo "File not in either directories.";
}
}
I feel like I'm way off with it.
You cannot use a url in file_exists, you need to use an absolute or relative path (relative to the runnings script) in the file-system of the server, so for example:
$dir = array(
"images/photosA/",
"../images/photosB/",
"/home/user/www/images/photosB/"
);
You can also use paths relative to the root of the web-server if you don't know the exact path and add the document root before that:
$dir = array(
$_SERVER['DOCUMENT_ROOT'] . "/images/photosA/",
$_SERVER['DOCUMENT_ROOT'] . "/images/photosB/"
);
(or you use it once, where you use file_exists())
Since you are running this script from within the root directory of your website, you won't need to define 'http://www.mydomain.com/' as this will cause Access Denied issues as it is not an absolute/relative file path. Instead, if the images/ folder is at the same directory level as your PHP script, all you will need to do is
$dir = array(
"images/photosA/",
"images/photosB/"
);
Otherwise, just add the absolute path as needed to make it work, but you can not put the. The rest seems as if it should work fine.
As the others said, file_exists() is for local files.
If you REALLY need to look for files over http, you can use :
$file = 'http://www.domain.com/somefile.jpg';
$file_headers = #get_headers($file);
if($file_headers[0] == 'HTTP/1.1 404 Not Found') {
$exists = false;
}
else {
$exists = true;
}
NOTE: This relies on the server returning a 404 if the image does not exist. If the server instead redirects to an index page or a pporly-coded error page, you could get a false success.
I am able to get the web path to the file like so:
$filename = 'elephant.jpg';
$path_to_file = $this->getSkinUrl('manufacturertab');
$full_path = $path_to_file . '/' . $filename;
But if the file doesn't exist, then I end up with a broken image link.
I tried this:
if(!file_exists($full_path)) {
Mage::log('File doesn\'t exist.');
} else {
?><img src="<?php echo $full_path ?>" /><?php
}
Of course that didn't work because file_exists does not work on urls.
How do I solve this?
1.)
Can I translate between system paths and web urls in Magento?
e.g. something like (pseudocode):
$system_path = $this->getSystemPath('manufacturertab');
That looks symmetrical and portable.
or
2.)
Is there some PHP or Magento function for checking remote resource existence? But that seems a waste, since the resource is really local. It would be stupid for PHP to use an http method to check a local file, wouldn't it be?
Solution I am currently using:
$system_path = Mage::getBaseDir('skin') . '/frontend/default/mytheme/manufacturertab'; // portable, but not pretty
$file_path = $system_path . '/' . $filename;
I then check if file_exists and if it does, I display the img. But I don't like the asymmetry between having to hard-code part of the path for the system path, and using a method for the url path. It would be nice to have a method for both.
Function
$localPath = Mage::getSingleton( 'core/design_package' )->getFilename( 'manufacturertab/' . $filename, array( '_type' => 'skin', '_default' => false ) );
will return the same path as
$urlPath = $this->getSkinUrl( 'manufacturertab/' . $filename );
but on your local file system. You can omit the '_default' => false parameter and it will stil work (I left it there just because getSkinUrl also sets it internaly).
Note that the parameter for getSkinUrl and getFilename can be either a file or a directory but you should always use the entire path (with file name) so that the fallback mechanism will work correctly.
Consider the situation
skin/default/default/manufacturertab/a.jpg
skin/yourtheme/default/manufacturertab/b.jpg
In this case the call to getSkinUrl or getFilename would return the path to a.jpg and b.jpg in both cases if file name is provided as a parameter but for your case where you only set the folder name it would return skin/yourtheme/default/manufacturertab/ for both cases and when you would attach the file name and check for a.jpg the check would fail. That's why you shold always provide the entire path as the parameter.
You will still have to use your own function to check if the file exists as getFilename function returns default path if file doesn't exist (returns skin/default/default/manufacturertab/foo.jpg if manufacturertab/foo.jpg doesn't exist).
it help me:
$url = getimagesize($imagepath); //print_r($url); returns an array
if (!is_array($url))
{
//if file does not exists
$imagepath=Mage::getDesign()->getSkinUrl('default path to image');
}
$fileUrl = $this->getSkinUrl('images/elephant.jpg');
$filePath = str_replace( Mage::getBaseUrl(), Mage::getBaseDir() . '/', $fileUrl);
if (file_exists($filePath)) {
// display image ($fileUrl)
}
you can use
$thumb_image = file_get_contents($full_path) //if full path is url
//then check for empty
if (#$http_response_header == NULL) {
// run check
}
you can also use curl or try this link http://junal.wordpress.com/2008/07/22/checking-if-an-image-url-exist/
Mage::getBaseDir() is what you're asking for. For your scenario, getSkinBaseDir() will perform a better job.
$filename = 'elephant.jpg';
$full_path = Mage::getDesign()->getSkinBaseDir().'/manufacturertab/'.$filename;
$full_URL=$this->getSkinUrl('manufacturertab/').$filename;
if(!is_file($full_path)) {
Mage::log('File doesn\'t exist.');
} else {
?><img src="<?php echo $full_URL ?>" /><?php
}
Note that for the <img src> you'll need the URL, not the system path. ...
is_file(), rather than file_exists(), in this case, might be a good option if you're sure you're checking a file, not a dir.
You could use the following:
$file = 'http://mysite.co.za/files/image.jpg';
$file_exists = (#fopen($file, "r")) ? true : false;
Worked for me when trying to check if an image exists on the URL
I'm learning CodeIgniter. I have a directory img with images (path /img/). I am trying to access it through CI view and check if exists with this code:
$av = '../../../img/content/users/'.$userID.'.jpg';
if(file_exists($av)) {
$avatar = $av;
} else {
$avatar = 'img/content/users/none.jpg';
}
Funny thing is, echoing <img src="'.$av.'"> works. What should I do?
CI always runs on index.php, so paths are always relative from there.
Assuming index.php and /img are at the same level in the root, try this:
$av = 'img/content/users/'.$userID.'.jpg';
if(is_file($av)) { // or better yet, make sure it's really an image
$avatar = $av;
} else {
$avatar = 'img/content/users/none.jpg';
}
Funny thing is, echoing <img src="'.$av.'"> works
It's because the browser is looking in a different place than the server. I'd recommend not using ../../relative/paths but using functions like base_url() and img(). When there are additional segments in the URL, relative paths break.
URLs and file paths are not the same. From the current URL ../../../img/content/users may and likely is something completely different than the file path on the hard disk where the view file is located.
Use following steps
1) Create a custom config file name site_config.php in config file (/application/config/) and paste following code
<?php
$config['base_url'] = "http://".$_SERVER['SERVER_NAME'] . str_replace(basename($_SERVER['SCRIPT_NAME']),"",$_SERVER['SCRIPT_NAME']);
if(!defined('DOCUMENT_ROOT')) define('DOCUMENT_ROOT',str_replace('system/application/config','',substr(__FILE__, 0, strrpos(__FILE__, '/'))));
$config['base_path'] = constant("DOCUMENT_ROOT");
?>
2) Edit autoload.php to autoload site_config.php (/application/config/autoload.php)
$autoload['config'] = array('site_config');
3) Then using following code to view image
$image_path = $this->config->item('base_path').'folder_name/'.$userID.'.jpg';
if(file_exists($image_path)) {
$avatar = $this->config->item('base_url').'folder_name/'.$userID.'.jpg';
} else {
$avatar = $this->config->item('base_url').'default_folder_name/profile.jpg';
}
echo '<img src="'.$avatar.'" />';
I think it will help you
Try this:
$av = './img/content/users/'.$userID.'.jpg';
For some reason this PHP code below will not work, I can not figure it out.
It is very strange,
file_exists does not seem to see that the image does exist, I have checked to make sure a good file path is being inserted into the file_exists function and it is still acting up
If I change file_exists to !file_exists it will return an images that exist and ones that do not exist
define('SITE_PATH2', 'http://localhost/');
$noimg = SITE_PATH2. 'images/userphoto/noimagesmall.jpg';
$thumb_name = 'http://localhost/images/userphoto/1/2/2/59874a886a0356abc1_thumb9.jpg';
if (file_exists($thumb_name)) {
$img_name = $thumb_name;
}else{
$img_name = $noimg;
}
echo $img_name;
file_exists() needs to use a file path on the hard drive, not a URL. So you should have something more like:
$thumb_name = $_SERVER['DOCUMENT_ROOT'] . 'images/userphoto/1/2/2/59874a886a0356abc1_thumb9.jpg';
if(file_exists($thumb_name)) {
some_code
}
http://us2.php.net/file_exists
docs say:
As of PHP 5.0.0, this function can also be used with some URL wrappers. Refer to List of Supported Protocols/Wrappers for a listing of which wrappers support stat() family of functionality.
file_exists does only work on the local file system.
So try this if you’re using localhost:
$thumb_name = 'images/userphoto/1/2/2/59874a886a0356abc1_thumb9.jpg';
if (file_exists($_SERVER['DOCUMENT_ROOT'].$thumb_name)) {
$img_name = SITE_PATH2.$thumb_name;
} else {
$img_name = $noimg;
}
Have you enabled the option which allows you to use external URLs? You can set it in php.ini:
allow_url_fopen = 1
You have to write the file path like "file:///C:/Documents%20and%20Settings/xyz/Desktop/clip_image001.jpg".
http://php.net/manual/en/function.file-exists.php
did you check the comments below?
Just reading parts of it, but there seem to be several issues.
Caching may be a problem.
When opening FTP urls it always returns true (they say in the comments)
...
Try Below one. Its working for me
define('SITE_PATH2', 'http://localhost/');
$noimg = SITE_PATH2. 'images/userphoto/noimagesmall.jpg';
$thumb_name = 'http://localhost/images/userphoto/1/2/2/59874a886a0356abc1_thumb9.jpg';
if ($fileopen = #fopen($thumb_name)) {
$img_name = $thumb_name;
fclose($fileopen);
}else{
$img_name = $noimg;
}
echo $img_name;
