Getting complete PATH of uploaded file - PHP

Viewed 59 times

I have a form(HTML, PHP) that lets the end user upload a file to update the database(MySQL) with the records in the uploaded file(specifically .csv). However, in the phpscript, I can only get the filename and not the complete path of the file specificed. fopen() fails due to this reason. Can anyone please let me know how I can work on finding the complete path?

HTML Code:

<html>
<head>
</head>
<body>
<form method="POST" action="upload.php" enctype="multipart/form-data">
    <p>File to upload : <input type ="file" name = "UploadFileName"></p><br />
    <input type = "submit" name = "Submit" value = "Press THIS to upload">
</form>
</body>
</html>

PHP Script:

<?php
   .....
......
   $handle = fopen($_FILES["UploadFileName"]["name"], "r"); # fopen(test.csv) [function.fopen]: failed to open stream: No such file or directory
?>

Answers

name refers to the filename on the client-side. To get the filename (including the full path) on the server-side, you need to use tmp_name:

$handle = fopen($_FILES["UploadFileName"]["tmp_name"], 'r');

Try this:

<script>
function lalala(str){
    alert(str);
}
</script>

<form action="" method="post" enctype="multipart/form-data" name="form1" id="form1">

<input type="file" name="file" id="file" onchange="lalala(this.value);" />
</form>

It worked for me in IE8 it gives me the complete path but in firefox and chrome is just prints the file name :(

Here's what worked best for me when trying to script this (in case anyone else comes across this like I did):

$ pecl -d php_suffix=5.6 install <package>
$ pecl uninstall -r <package>

$ pecl -d php_suffix=7.0 install <package>
$ pecl uninstall -r <package>

$ pecl -d php_suffix=7.1 install <package>
$ pecl uninstall -r <package>

The -d php_suffix=<version> piece allows you to set config values at run time vs pre-setting them with pecl config-set. The uninstall -r bit does not actually uninstall it (from the docs):

vagrant@homestead:~$ pecl help uninstall
pecl uninstall [options] [channel/]<package> ...
Uninstalls one or more PEAR packages.  More than one package may be
specified at once.  Prefix with channel name to uninstall from a
channel not in your default channel (pecl.php.net)

Options:
  ...
  -r, --register-only
        do not remove files, only register the packages as not installed
  ...

The uninstall line is necessary otherwise installing it will remove any previously installed version, even if it was for a different PHP version (ex: Installing an extension for PHP 7.0 would remove the 5.6 version if the package was still registered as installed).

You probably can't. Many browsers these days don't send that information, as it can give attackers information about the user's system.

Never used any of those, but they look interesting..

Take a look at Gearman as well.. more overhead in systems like these but you get other cool stuff :) Guess it depends on your needs ..
