I am working with PHP and would like to get a remote file path location so that I can read file contents.
I would like the user to direct to a particular file, which can be located anywhere in the computer, so that it can be processed by the script.
Thanks
You can offer a user the ability to locate a file on their local computer and submit it to you via a web form, like..
<form id="myForm" enctype="multipart/form-data" action="/formHandler.php" method="post" >
<label for="fileUpload">File to Upload:</label>
<input name="fileUpload" id="fileUpload" type="file" /><br />
<input name="submit" id="submit" type="submit" value="Upload Now"></form>
Then you can process it on your side with PHP, or whatever you have on the server end. Since PHP is one of your tags, you can learn more on how to access, and work with, on the server end from the PHP reference site:
http://www.php.net/manual/en/features.file-upload.post-method.php
I hope I understood your question correctly..

I am writing a fingerprint web application. I will read the fingerprint from user using ActiveX controls.
After that, I will get the image in the webpage. I found that the examples I found in the web requires users to click an upload image button and choose image from it.
Like the example below:
<form action="upload_file.php" method="post" enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="file" id="file"><br>
<input type="submit" name="submit" value="Submit">
</form>
Some tells me that I need to use ftp to upload the file.
Can I have another choice? The best method is that I can use Http to upload.
You could send a data URI to the server using AJAX
Convert Data URI to File then append to FormData
However if you are using ActiveX, why not have the ActiveX send the data to the server from within the ActiveX?
I know this is an old question and I have found lots of tutorial on SO however, they cannot solve my problem.
I use my mac to set up a localhost for web programming and I try to upload a jpg file to my localhost directory "/Library/WebServer/Documents". But it gives hint unable to move.
my front end code is:
<form action="upload_file.php" method="post"
enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="file" id="file"><br>
<input type="submit" name="submit" value="Submit">
</form>
The php(upload_file.php) code is(there is some other checking codes for php file, copied from w3school):
move_uploaded_file($_FILES["file"]["tmp_name"] , "/Library/WebServer/Documents" . $_FILES["file"]["name"]);
And after I click the submit button, there is sth wrong printed on the screen.
Moreover, I did not find any tmp file in the file "/private/var/tmp", in which should be a tmp file...
make sure your php file has enough rights to write into the directory.
check if print_r($_FILES); lists anything, especially the size is important.
I'm using wampserver on my computer and wrote a simple html-form:
<form name="test" action="upload_file.php" method="post">
<label for="file">Filename:</label>
<input type="file" name="picurl" id="file" ><br>
<input type="submit" name="submit" value="Submit" >
</form>
When I click on "browse" and open a file ,for example pil.png it shows in the input textarea the full path(C:\Users\hope\Desktop\images\pil.png)
I want this exact link saved but when I try to catch it $name = $_POST["name"];it only displays this- "pil.png" not the full path. why?
You cannot get the complete local file path. Only the file data itself and its name is submitted to the server. The file path being displayed in the input element is only visual styling, it has no functionality.
File elements are very limited for security reasons, and that's a good thing.
The browser doesn't submit the full path because it would be a privacy problem, you would be exposing your file system structure to the server. It's not relevant to the server and the server doesn't need to know where the file was located on the client's filesystem.
You are getting only file_name because you are not asking for path.
to get full path you have to use
public string SplFileInfo::getRealPath ( void )
try
var_dump($_FILES['picurl']);
I'm developing an image host and wish to have images uploaded to a separate server from my web content, eg: http://i1.mysite.com instead of http://mysite.com/uploads. But I'm having some trouble figuring out how to do that.
Say I have this form:
<form action="http://mysite.com/upload" method="post" accept-charset="utf-8" enctype="multipart/form-data">
<input type="file" name="image" id="file_upload" />
<input type="submit" value="Upload" id="upload_submit" />
</form>
That will send an image file to /upload, where I can validate the file and save it, but that will be on the same server as the website is hosted, rather than a dedicated storage server. How can I achieve what I want without having the images uploaded on the same server as my web site?
I could always do:
<form action="http://i1.mysite.com/upload" method="post" accept-charset="utf-8" enctype="multipart/form-data">
<input type="file" name="image" id="file_upload" />
<input type="submit" value="Upload" id="upload_submit" />
</form>
which would send the image file to another server, but then when the image upload is complete I'd be redirected to http:/i1.mysite.com/upload.
Anyone have any experience with this and can recommend a course of action? Thank you!
Don't upload to the image server. Such content-specific servers should be optimized for serving up content, and not have to deal with consuming content.
Let the upload form send to your main site's server. You can then use other protocols to transfer the uploaded file(s) to the image servers. rsynch, scp, etc... This way you have all your "control" code in one location, and don't have to worry about synching databases and whatnot between multiple servers - all the data is kept on your main server, and the image servers just passively spit out image data.
I would recommend decoupling these two ideas. First, upload the image to your servers and in a separate process (perhaps a scheduled cron) move the images to other server. You likely do not want the user waiting for two uploads to finish.
Like the others have said, what you're trying to do is not optimal. If you really want to continue to do this, I'd suggest having the form submit to a PHP script which then processes it and places the file where it needs to be and then saves whatever information to the database that is necessary. You'll need to evaluate the best protocol for the data transfer from one server to the other. You'll probably end up using Curl, which you can learn about here and here as well as the curl docs
You could upload the image to your image host, and have it redirect back to your website afterward. One way to do this would be to add hidden "success" and "failure" URL inputs to the form:
<form action="http://i1.mysite.com/upload" method="post" accept-charset="utf-8" enctype="multipart/form-data">
<input type="file" name="image" id="file_upload" />
<input type="submit" value="Upload" id="upload_submit" />
<input type="hidden" name="success" value="http://mysite.com/success" />
<input type="hidden" name="failure" value="http://mysite.com/failure" />
</form>
The upload script on your image host would then redirect to the supplied URL after a successful upload:
<?php
.. handle uploaded file ..
if ($success) {
header ('Location: ' . $_REQUEST ['success']) ;
}
else {
header ('Location: ' . $_REQUEST ['error'] . '?message=' . $message) ;
}
?>
I want to upload the files to this address: http://chusmix.com/Imagenes/grupos and I'm trying with this simple this code but it doesn't work:
<form enctype="multipart/form-data" method="post" action="http://chusmix.com/Imagenes/grupos">
Please specify a file:<br>
<input type="file" name="datafile" size="40">
</p>
<div>
<input type="submit" value="Send">
</div>
</form>
Oddly enough, the first result of a Google search yielded this rather helpful tutorial. Why not read it?
Read the PHP manual chapter "Handling file uploads":
http://php.net/manual/en/features.file-upload.php
The way you think uploads work is not the way they work. The form posts to the script you want to handle the request, not the location you want the uploads to be. When you upload a file to Apache, it places that file in the temporary directory of the computer (in Linux, that's /tmp by default).
Your script has to move the file from the temp directory to wherever you want it to be. The manual has plenty of code showing you how.
Make sure the form is loaded via
http://chusmix.com/Imagenes
The browsers wont you allow to upload to a unkown website (Same origin policy).
Edit your form
<form enctype="multipart/form-data" method="post" action="/grupos">
