Trouble accessing HTML form data using PHP - php

I'm trying to build a file upload form and I'm having trouble with the very basics. My form is this:
<html>
<body>
<form action="fileuploader.php" method="POST" enctype="multipart/form-data">
<input type="file" name="filename" />
<input type="submit"/>
</form>
</body>
</html>
My php code so far is one line and it doesn't do anything:
<?php
echo $_POST['filename'];
?>
The idea (at this point) is just to display the name of the file entered in the form. What am I doing wrong?

Based on your code I modified it. Have a try it.
HTML Part
<html>
<body>
<form action="fileuploader.php" method="POST" enctype="multipart/form-data">
<input type="file" name="filename" />
<input type="submit" name="submit" />
</form>
</body>
</html>
PHP
if (isset($_POST['submit'])) {
// Check if files array is not empty
if (!empty($_FILES)) {
$imageName = $_FILES['filename']['name'];
echo $imageName;
// Insert your code related to upload
}
}

You can print the filename using the following code:
<?php
echo $_FILES["filename"]["name"];
?>

HTML not posting file to PHP

Here is my code:
<html>
<body>
<div>
<form action="<?=$_SERVER['PHP_SELF'];?>" method="post">
<input type="file" id="myFile" name="filename">
<input type="submit" name="Submit">
</form>
</div>
<?php
if(isset($_POST['Submit']))
{
$file = $_POST["myFile"];
echo("hello");
}
?>
</body>
</html>
when I run it and input a file it says: Undefined array key "myFile"
what am I doing wrong?
Uploaded files don't get added to the $_POST array but they are loaded into the $_FILES array. Try check that out.
You can then use the move_uploaded_file() to save it wherever you want.
Important: as soon as the script execution is over, the temporary uploaded file is removed if it was not saved somewhere else with move_uploaded_file().
The request transfers the data using the names of the form fields and not the IDs, the file data can be found in the global variable $_FILES.
Use $file = $_FILES['filename']['name']; for the name of the uploaded file
or $file = $_FILES['filename']['tmp_name']; for the temporary file path of the uploaded file.
Add on form enctype="multipart/form-data"
This value is necessary if the user will upload a file through the form.
Your file type name is "filename".
<html>
<body>
<div>
<form action="<?=$_SERVER['PHP_SELF'];?>" method="post" enctype="multipart/form-data">
<input type="file" id="myFile" name="filename">
<input type="submit" name="Submit">
</form>
</div>
<?php
if(isset($_POST['Submit']))
{
$file = $_FILES['filename']['tmp_name'];
echo("hello");
}
?>
</body>
</html>

Can't display image I uploaded in PHP

I'm trying to upload an image and display after uploading, the upload part works fine but image can't display.
Any answers?
Code:
<!DOCTYPE html>
<html>
<body>
<?php
echo <<<_END
<form method="post" action="upload.php" enctype="multipart/form-data">
<input type="file" name="fupload" size="100000" accept="image/*">
<input type="submit" name="upload" value="Upload">
</form>
_END;
if($_FILES){
$name = $_FILES['fupload']['name'];
move_uploaded_file($name = $_FILES['fupload']['tmp_name'], $name);
echo "<br><img src='$name'>";
}
?>
</body>
</html>
Browser:
Image can't display
nevermind, the problem is move_upload ($name=xxxx, $name), it means you assign to $name the tmp source !
here is a working code
<!DOCTYPE html>
<html>
<body>
<form method="post" action="upload.php" enctype="multipart/form-data">
<input type="file" name="fupload" size="100000" accept="image/*">
<input type="submit" name="upload" value="Upload">
</form>
<?php if($_FILES)
{
$source=$_FILES['fupload']['tmp_name'];
$target1 = $_FILES['fupload']['name'];
move_uploaded_file($source,$target1);
?>
<br>
source=<?php echo htmlspecialchars($source);?>
<br>
target=<?php echo htmlspecialchars($target1);?>
<img src="<?php echo htmlspecialchars($target1);?>"
<?php
} // if $_FILES
?>
</body>
</html>
Ok, following comment, it seems $name point To à path not accessible for external user. Try a link like this $name="c:\path To your base path\www\et.png"
Edit: supposing you have a existing www folder , where you find your index.php. It may be called public.

Upload file to server and return name of file

I'm trying to upload a file to my php server, then return the name of the file to display in the html document. But I get the following
`error: Objektet wasn't found! The requested address was not found on this server. The link on the previous page appears to be incorrect or out of date Error 404
localhost
Apache/2.4.27 (Win32) OpenSSL/1.0.2l PHP/7.1.8`
My html Doc
<html>
<body>
<form method="post" enctype="multipart/form-data" action="server.php">
<input type="file" name="fileToUpload" id="fileToUpload" size="35">
<br>
<br>
<input type="submit" value="Upload" name="submit">
</body>
</html>
My php doc
<?php
header('Content-type: text/plain');
if(isset($_POST["fileToUpload"])){
$file = $_FILES["fileToUpload"];
echo("File: ".$file);
}
?>
You have many errors in PHP
<?php
if(isset($_FILES["fileToUpload"])){
$file = $_FILES["fileToUpload"]["name"];
echo "File: ".$file;
}
?>
HTML
<html>
<body>
<form method="post" enctype="multipart/form-data" action="server.php">
<input type="file" name="fileToUpload" id="fileToUpload" size="35">
<br>
<br>
<input type="submit" value="Upload" name="submit">
</body>
</html>
Errors
1.if(isset($_POST["file"])){ its not post it should be $_FILES["fileToUpload"]) since its a file upload
$file = $_FILES["file"]; and in your html you have defined file name as fileToUpload but your accessign unknown name so it should be $file = $_FILES["fileToUpload"]["name"];
In your PHP script you are asking for a form name that does not exist. In your form, the variable is called fileToUpload but in your script you are checking for $_POST['file'].
Also, the global $_FILES is an array with information about the file, so you cannot use echo to show its content. Use echo $_FILES['fileToUpload']['name'] since $_FILES['formFieldName']['name'] will display the original name of the file on the client machine.

PHP input file error, echo file name with Post method

I'm trying to take posted input file name, I'm not uploading anywhere.
I just need the name of posted filename so I'm trying this code;
<form method="post" enctype="multipart/form-data" role="form">
<input type="file" id="file" name="file">
<input type="submit" name="submit" value="Submit Form">
</form>
<?php
if(isset($_POST['submit'])){
echo $_FILES['file'];
}
?>
If I change enctype="multipart/form-data" into form tag, it's ok, but I need this tag.
You still need the enctype attribute, as the files will not be available without it.
if (isset($_POST['submit'])) {
echo $_FILES['file']['name'];
}
use
echo $_FILES['file']['name'];
instead of
echo $_FILES['file'];
$_FILES['file'] contains array of properties of uploaded file. use print_r instead. It will work fine.
you can get file name like that
$name = $_FILES['file']['name'];
this code is working fine
<form method="post" enctype="multipart/form-data" role="form">
<input type="file" id="file" name="file">
<input type="submit" name="submit" value="Submit Form">
</form>
<?php
if(isset($_POST['submit'])){
echo "<pre>";
print_r($_FILES['file']) ;
}
?>

HTML form for file upload won't return file name

I have a simple HTML file with a form to upload a file and PHP code to process the uploaded file. I've tried a bunch of input types and they all work except for input type="file". Nothing gets displayed. The code is attached.
<!DOCTYPE html>
<html>
<body>
<form action="upload.php" method="post" enctype="multipart/form-data"> Select image to upload:
<input type="file" name="test.f" id="test.f">
<input type="submit" value="Upload Image" name="submit">
</form>
</body>
</html>
The processing php code is:
<?php
echo "Hello world";
echo $_FILES["test.f"];
?>
you should call the file by name if it does not work please change the file name in your form
name="test"
$_FILES["test"]['name'];
