It appears as though the data from my form never reaches the server fully because the only parameter populated in the $_FILES array is 'name'. , Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers ,Thanks for contributing an answer to Stack Overflow!, Stack Overflow Public questions & answers

For example, here is a vardump of $_FILES:

array(1) {
   ["gameimage"] => array(1) {
      ["name"] => string(15)
      "Donkey-kong.gif"
   }
}

An associative array of items uploaded to the current script via the HTTP POST method. The structure of this array is outlined in the POST method uploads section. ,This is a 'superglobal', or automatic global, variable. This simply means that it is available in all scopes throughout a script. There is no need to do global $variable; to access it within functions or methods. ,$_FILES — HTTP File Upload variables, $http_​response_​header

see http: //php.net/manual/en/features.file-upload.post-method.php for documentation of the $_FILES array, which is what I came to this page for in the first place.

size: Indicates the size of the uploaded file in bytes.,In this article, I’ll explain the basics of file upload in PHP. Firstly, we’ll go through the PHP configuration options that need to be in place for successful file uploads. Following that, we’ll develop a real-world example of how to upload a file., type: Contains the mime type of the uploaded file.,Now let's build a real-world example to demonstrate file upload in PHP.

If you're not sure where to find your php.ini file, you can use the php_ini_loaded_file() to locate it. Just create a PHP file on your server with the following line, and open it from the browser.

< ? php echo php_ini_loaded_file(); ? >

$_FILES is a PHP super-global and variable. It contains names, sizes, and mime types of files uploaded in the current HTTP request. ,For example, if the user uploads the foo directory, the $_FILES array name value only contains the file name without the relative path.,full_path array key in the $_FILES super-global is a new feature in PHP 8.1. The existing name array values are not modified, and they continue to only contain the file name without the file path. ,In PHP 8.1, the $_FILES also contains a new key named full_path, that contains the full path as submitted by the browser.

In HTML file upload fields, it is possible to upload an entire directory with the webkitdirectory attribute. This feature is supported in most modern browsers.

<form action="" method="post" enctype="multipart/form-data">
   <input name="myupload[]" type="file" webkitdirectory multiple />
   <input type="submit" />
</form>

file - used to just allow a normal file upload from the desktop only.,filemanager - the way to attach one or more files as a set,File appears in the text or as an attachment in the form.,When using editor element you need to preprocess and postprocess the data:

$mform - > addElement('filepicker', 'userfile', get_string('file'), null,
   array('maxbytes' => $maxbytes, 'accepted_types' => '*'));

For example, you may need to re-populate a form after checking it for validation errors.,Note: Some JavaScript libraries such as Backbone may send input to the application as JSON. You may access this data via Input::get like normal.,When working on forms with "array" inputs, you may use dot notation to access the arrays:

$_FILES['uploadedfile']['type']: The mime type of the file,$_FILES['uploadedfile']['size']: The size of the file in bytes,$_FILES['uploadedfile']['name']: The original name of the file on the client machine,When the PHP interpreter receives an HTTP POST method request of the multipart/form-data encoding type, the script will create a temporary file with a random name in a temporary directory on the server, for example, /var/tmp/php6yXOVs. The PHP interpreter will also populate the global array $_FILES with the information about the uploaded file as follows.

A simple file upload form typically consists of an HTML form which is presented to the client and a server-side script that processes the file being uploaded. The following example contains such an HTML form and a server-side script written in PHP.

<form enctype="multipart/form-data" action="uploader.php" method="POST">
  <input type="hidden" name="MAX_FILE_SIZE" value="100000" />
  Choose a file to upload:
  <input name="uploadedfile" type="file" />
  <input type="submit" value="Upload File" /> 
</form>
<?php 
  $target_path = "uploads/";
  $target_path = $target_path . basename($_FILES['uploadedfile']['name']);
  if (move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
    echo "The file " . basename($_FILES['uploadedfile']['name']) . " has been uploaded"; 
  } else {
    echo "There was an error uploading the file, please try again"; 
  }
?>

One possible way an attacker could bypass a file extension blacklist on an Apache HTTP Server is to first upload an .htaccess file with the following contents.

AddType application / x - httpd - php.jpg

A far better approach to securing file upload forms is to employ a whitelisting approach. With this approach, only files that match a known and accepted file extension are allowed. However, in some cases, this approach will not work as expected. For example, when the Apache HTTP Server is configured to execute PHP code, there are two ways one can specify this: using the AddHandler directive or using the AddType directive. If the AddHandler directive is used, all filenames containing the .php extension (.php, .php.jpg) will be executed as PHP scripts. Therefore, if an Apache HTTP Server configuration file contains the following, it may be vulnerable:

AddHandler php5 - script.php

Another common method used to secure file upload forms is to restrict execution of scripts in an upload directory using .htaccess configuration that would typically contain the following:

AddHandler cgi - script.php.php3.php4.phtml.pl.py.jsp.asp.htm.shtml.sh.cgi Options– ExecCGI

These types of validation controls allow an application to do regular-expression checks upon the file that is being uploaded, to check that the extension of the file being uploaded is specified in the list of allowed extensions. Below is a sample code taken from Microsoft’s website.

<asp:FileUpload ID="FileUpload1" runat="server" /><br /> 
<br /> 
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" 
Text="Upload File" /> <br /> 
<br /> 
<asp:Label ID="Label1" runat="server"></asp:Label> 
<asp:RegularExpressionValidator 
id="RegularExpressionValidator1" runat="server" 
ErrorMessage="Only mp3, m3u or mpeg files are allowed!" 
ValidationExpression="^(([a-zA-Z]:)|(\\{2}\w+)\$?)(\\(\w[\w].*)) 
+(.mp3|.MP3|.mpeg|.MPEG|.m3u|.M3U)$" 
ControlToValidate="FileUpload1"></asp:RegularExpressionValidator> 
<br /> 
<asp:RequiredFieldValidator 
id="RequiredFieldValidator1" runat="server"
ErrorMessage="This is a required field!" 
ControlToValidate="FileUpload1"></asp:RequiredFieldValidator>
.htaccess
deny from all < files ~ “^w+.(gif|jpe?g|png)$”>
