I want to know whether there is anyway to get the client side absolute path of selected file!
$_FILES['xml_file']['tmp_name']; This also provides path of selected file but its server side path... Its result is something like this C:\xampp\tmp\php2679.tmp
I want C:\Users\Sami\Desktop\data\myfile.xml where my actual file is placed.
Because I want this actual path to use again for fetching and saving etc automatically (by code).
you may try echo realpath($_FILES['xml_file']['name']); on your php.
then the output will be:
C:\Users\Sami\Desktop\data\myfile.xml
When you click the browse button it chooses the file. When you click the submit button, the entire file is being sent from the browser to the web server, and PHP is indeed putting the entire file in the php servers temp directory. Then, your script gets called.
So when you try to get absolute path from $_FILES['xml_file']['name'] or $_FILES['xml_file']['tmp_name'] or realpath($_FILES['xml_file']['name']) you will get the path on server.
The solution to this problem would be to simply copy the file somewhere, and not ask for the file upload again. You'll need to be sure that where ever you copy it to on your web server, that the server has permissions to do so. Usually that involves giving write permissions for the user which the web server runs as (usually user 'apache' or 'nobody' for apache based servers) to a special directory you've created for the purpose.
Copy is available in PHP. http://us3.php.net/manual/en/function.copy.php
Your only trick will be what to name it so you can find it again for the second request, and deciding what directory to put it into.

I am trying to download an object/ file from AWS S3 to the local computer. I would like to provide the user with the opportunity to provide the local path. In HTML we have the
<form> and <input type="file">
elements to provide the user with the option to select a file from the file system for upload. How do we do the reverse? Any pointers would be greatly appreciated.
You can't.
Being able to do so would risk websites trying to put stuff in /etc/hosts, ~/.bash_profile, C:\Windows\System32, etc. You can set a (suggested) filename, but it's going to go to the browser's preferred Downloads folder.
It's a security issue to write anywhere you want to the filesystem. You can present it as a download (application/octet-stream / Content-Disposition) but the user's browser gets the right to choose in the end regardless.
You can force a file to download instead of display on a page from the server with a specific filename only, but it stops there. The browser has the choice of popping up a Save As dialog or saving it in the default Downloads folder.
Incidentally, when a user chooses to upload a file, you don't actually get the path either - you get a fake path and a user-defined real filename. On Windows Chrome, it sends something typically like c:\fakepath\ so it doesn't reveal overly-personal information in the path.
So essentially I want to insert the Path into my Database, as a string, I am not interested in uploading it - I just want local users to browse to the file then submit the form and the path to the file is added as a string. So when I echo this out into a url, people on the network can click the link to download it from the network location.
$location = fopen($_FILES["location"]["tmp_name"], 'r');
I've tried the above but I guess the file needs to be uploaded for it to get the path.
Any ideas?
Unfortunately PHP will not help you with this as it requires you to actually upload the file.
Likewise, as was mentioned in the comment you are not able to get the local file path either from the form. This is a browser standard and is done for security purposes. You can read more about it here: https://stackoverflow.com/a/4176605/8518859
The only solution in your case is to provide a text input and ask the user to paste the network path to the file. Perhaps if you provide them simple instructions on how to get the network path it will make their task easier.
i have GoDaddy shared webspace with FTP access that contains a folder with images. These images are changing every day.
Im looking for advice on what i need to do to get these images onto my server in the workplace, maybe every hour or so. The server doesnt have IIS installed is there any other way to do this?
Am i able to do a PHP script that can put all the images onto the server using the ip or something?
I had the same issue as I had two images on a remote server which I needed to copy to my local server at a predefined time each day and this is the code I was able to come up with...
try {
if(#copy('url/to/source/image.ext', 'local/absolute/path/on/server/' . date("d-m-Y") . ".gif")) {
} else {
$errors = error_get_last();
throw new Exception($errors['type'] . " - " . $errors['message']);
};
} catch(Exception $e) {
//An Error Occurred Downloading The Requested Image
//Place exception handling code here
};
I then created a cron job which ran this file on a daily basis but you would be able to run is as frequently as you needed to based on how frequently the source image changes on the source server.
A few points to explain the code...
As the code is run in the background I use the # symbol to silence visual references to any errors which occur with the copy command as they won't be viewable anyway. Instead if copy results in an error it returns false and triggers throwing a new exception which takes the error type and error message and throws a new exception for it which can then be handled in the catch block and can be actioned however you need such as making a local log entry, sending an error email, whatever you need.
As the second paramater in the copy command you will see that the path results in the filename being named based on the current date. This name can be anything but needs to be unique in the destination for it to work. If you plan on overwritting the image each time the copy is done then you can statically code the name as the same name but if you want to maintain a history then you would need to come up with a file naming solution on your local server to ensure that the files don't get overwritten each time the cron runs.
The first parameter of the copy statement has been written on the assumption that the source image file is named the same each time, if the name changes the you will need to identify how the naming is achieved and code a variable to build that name and insert it as the source filename.
This code does not alter the format of the source image file so to ensure no corruption occurs and the image can still be shown after the copy you need to ensure that the source image file and the local copy of the image file have the same file extensions, so if the source image file is a .gif file then you need to make sure the file extension in the second copy parameter is also set to .gif
I'll try to answer here instead of continuing the comment-spam ;)
you got your webspace with FTP access. let's just call it webspace;
then you got your server at your workplace. let's just call it workplace;
after all you need one server (also can be webspace for example) where you are able to run PHP. let's call it php-server;
step 1
at the workplace setup a FTP server, for example FileZilla. you setup your FTP server so that you can connect to it. so make an account and set it up so you can access the folder(s) where you want to save your images. also make sure you got access from outside your workplace - firewall settings etc.
step 2
if you can run your PHP scripts on your webspace this would be the easiest way. you can directly access the image files, establish a connection to your FTP server at workplace and upload the files.
if the PHP server is somewhere else, you have to establish a connection from the php-server to your webspace; download your files to your php-server; upload your files to the FTP server at your workplace.
will be a bit of work as you can see, but should be possible to do.
Create a .bat file that uses the ftp command line functions to get the data you want from the server. Save that .bat file somewhere and create a Scheduled Task to run the script every hour.
You can even store the actual sequence of ftp commands in a separate file (e.g. ftpcmd.dat) and call them from the script
ftp -n -s:ftpcmd.dat SERVERNAME.COM
Example ftp command file:
user MyUserName
Password
bin
cd \your\path\images
mget * C:\Temp\
quit
I have a recursive function which generates about 200.txt files. I am running this application on a local server.
Basically, the front end just has a file upload field, which you just choose a .csv, which it then generates all the .txt files from that, but rather than saving them on the wamp server, is it possible to save them in a specific location?
Example, if I put another field in my front end called 'fileLocation', and the user types in the pathname.
Obviously i'd have to check if it's a directory etc, but is this possible to say save all the files on:
/Volumes/computer/Users/username/Desktop/test/
I'm not sure where to proceed with this.
No, is not possible to access computer files this way by using a localhost. You could zip all files and make the browser download them. Like is described here
So I am running xampp and wordpress. I have an image uploaded to the uploads directory named "avatar.jpeg". It displays just fine. But when I delete it and upload a new image file named "avatar.jpeg", the server doesn't reflect the change and just shows the old file. But when I open the file in Eclipse or my explorer, then the server starts showing the change and displays the new image.
This is probably something basic which I never learned about. I tried chmod to set the file permissions on the new file but that didn't help.
The file will be cached in your browser. To force a reload, append an arbitrary variable to your file, e.g. <img src="yourfile.jpg?1234567" />
I also guess it's a caching issue like freddy K. does.
I would suggest to configure ETags on your Server.
Simply appending something to the URL may only help you when the appended string is changing on every update of the requested file(using the current timestamp or similar all the time will force the client to download the file on every request and slow down the page).
