With PHP, I would like to post file directly to /dev/null, without writing to disk. I have this upload.php, which basically moves the file from a /tmp/yyXXXx to the /tmp/repos dir, but instead I would want to directly drop it to /dev/null.
Can $_FILES['userfile']['tmp_name'] be set or overridden to /dev/null?
Also, I tried setting the upload_file_path to /dev/null in php.ini file.
?php
$uldir = '/tmp/repos/';
$ulfile = $uldir . basename($_FILES['userfile']['name']);
if (move_uploaded_file($_FILES['userfile']['tmp_name'], $ulfile)) {
echo "Uploaded successfully.\n";
} else {
echo "Could not upload file!\n";
}
?>

So i want my page to show the image whose path I am getting from the mysql database and displaying on the same screen. This is my code, I have tried everything, please let me know where I'm going wrong.
while ($row = mysqli_fetch_array($return_data)) {
echo "ID:".$row['demo_id']."<br>";
echo "Name: ".$row['demo_name']."<br>";
echo "Version: ".$row['demo_version']."<br>";
echo "Details: ".$row['demo_details']."<br>";
echo "File Link: ".$row['file']."<br>";
$new = $row['file'];
echo '<img src = \"$new\"/>';
}
mysqli_free_result($return_data);
echo "Data retrieved successfully!"."<br>";
?>
<img src = "<?php echo $new?>">
echo "File Link: " returns me the whole path of the uploaded file.
How do I render the image at that path in the same page?
neither of the image tags are working. Thanks in advance!
edit
File Link: C:/Apache24/htdocs/demo_webpages_project/neweruploads/footer.jpg
this is the path I get as an output.
Basically this is the folder where I have uploaded the image from another php file
<?php
//this module is used to temporarily store the uploaded file to the server
$target_dir = "random/"; //we randomly assign a value to the upload target directory
$target_file = $target_dir . basename($_FILES["image_file"]["name"]); /*here ["name"] is the original name of the file before it was updated
target file is assigned this name by appending it to the $targer_dir
now target_file is the uploaded file name along with the path*/
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);/*this returns various kind of info about the path for eg Directory, Basename
in our case it returns extension of the file*/
//this sub module is to check whether the file is really an image file
if(isset($_POST["submit"])) { //isset is used to confirm whether the value has actually being submitted
$check = getimagesize($_FILES["image_file"]["tmp_name"]);/*here ["tmp_name"] is the location of temporary file on server
getimagesize confirms image format by returning dimensions etc*/
if($check !== false) {
echo "A file is of an image format<br>";
}
else {
echo "The file is not an image!<br>";
}
}
//Test module to upload files to a destination directory and check whether they have been uploaded or not
if (is_uploaded_file($_FILES['image_file']['tmp_name']) && $_FILES['image_file']['error']==0) { /*code to check two things: 1. whether the file exists in the temp memory 2. whether the file has any error*/
$path = 'C:\Apache24\htdocs\demo_webpages_project\neweruploads\\' . $_FILES['image_file']['name']; /*this sets the destination directory(along with expected file name)*/
if (!file_exists($path)) { //if the file does not exists at that path
if (move_uploaded_file($_FILES['image_file']['tmp_name'], $path)) { //use the php file move function to move it
echo "The file was uploaded successfully."; //success
}
else {
echo "The file was not uploaded successfully."; //failure
}
}
else {
echo "File already exists. Please upload another file."; //detects existence of file with exact same name
}
}
else {
echo "The file was not uploaded successfully."; //if any problem with original uploading
echo "(Error Code:" . $_FILES['image_file']['error'] . ")";
}
?>
Does this help?

http://localhost:8080/demo_webpages_project/download.php?project_name=footer&version=&submit=Search
this is my local directory path.
the solution you provided is allowing me to read images which are in the demo_webpages_project folder pointing directly there), not to neweruploads folder
If your uploaded files are stored in the neweruploads subdirectory, then replace this code:
$new = $row['file'];
echo '<img src = \"$new\"/>';
By this one :
$new = basename( $row['file'] ); // GET FILE NAME ONLY, GET RID OF PATH.
echo '<img src = \"neweruploads/$new\"/>'; // FILENAME WITH UPLOAD PATH.

From the script below, can anyone tell me what I've done wrong to get the warning message on output of the script? The upload script is -
Code:
<?php
// Access the $_FILES global variable for this specific file being uploaded
// and create local PHP variables from the $_FILES array of information
$fileName = $_FILES["thumb"]["name"]; // The file name
$fileTmpLoc = $_FILES["thumb"]["tmp_name"]; // File in the PHP tmp folder
$fileType = $_FILES["thumb"]["type"]; // The type of file it is
$fileSize = $_FILES["thumb"]["size"]; // File size in bytes
$fileErrorMsg = $_FILES["thumb"]["error"]; // 0 = false | 1 = true
$fileSplit = explode(".", $fileName); // Split file name into an array using the dot
$fileExt = end($fileSplit); // Now target the last array element to get the file extension
// START PHP Image Upload Error Handling --------------------------------------------------
if (!$fileTmpLoc) { // if file not chosen
echo "ERROR: Please browse for a file before clicking the upload button.";
exit();
} else if($fileSize > 5242880) { // if file size is larger than 5 Megabytes
echo "ERROR: Your file was larger than 5 Megabytes in size.";
unlink($fileTmpLoc); // Remove the uploaded file from the PHP temp folder
exit();
} else if (!preg_match("/.(gif|jpg|png)$/i", $fileName) ) {
// This condition is only if you wish to allow uploading of specific file types
echo "ERROR: Your image was not .gif, .jpg, or .png.";
unlink($fileTmpLoc); // Remove the uploaded file from the PHP temp folder
exit();
} else if ($fileErrorMsg == 1) { // if file upload error key is equal to 1
echo "ERROR: An error occured while processing the file. Try again.";
exit();
}
// END PHP Image Upload Error Handling ----------------------------------------------------
// Place it into your "Avatars" folder mow using the move_uploaded_file() function
$moveResult = move_uploaded_file($fileTmpLoc, "Avatars/$fileName");
// Check to make sure the move result is true before continuing
if ($moveResult != true) {
echo "ERROR: File not uploaded. Try again.";
unlink($fileTmpLoc); // Remove the uploaded file from the PHP temp folder
exit();
}
unlink($fileTmpLoc); // Remove the uploaded file from the PHP temp folder
// Display things to the page so you can see what is happening for testing purposes
echo "The file named <strong>$fileName</strong> uploaded successfully.<br /><br />";
echo "It is <strong>$fileSize</strong> bytes in size.<br /><br />";
echo "It is an <strong>$fileType</strong> type of file.<br /><br />";
echo "The file extension is <strong>$fileExt</strong><br /><br />";
echo "The Error Message output for this upload is: $fileErrorMsg";
?>
My form is this
<?php
$profile_pic_btn = 'Toggle Avatar Form';
$avatar_form = '<form id="avatar_form" enctype="multipart/form-data" method="POST" action="process_reguser_exec.php">';
$avatar_form .= '<h4>Change your avatar</h4>';
$avatar_form .= '<input type="file" name="thumb">';
$avatar_form .= '<p><input type="submit" value="Upload"></p>';
$avatar_form .= '</form>';
?>
The output is this
Warning: unlink(C:\xampp\tmp\php8E40.tmp): No such file or directory in C:\xampp\htdocs\MyWebSite\process_reguser_exec.php on line 37
The file named image1.JPG uploaded successfully.
It is 3337452 bytes in size.
It is an image/jpeg type of file.
The file extension is JPG
The Error Message output for this upload is: 0
Line 37 is this
unlink($fileTmpLoc); // Remove the uploaded file from the PHP temp folder
When you have used the move_uploaded_file command, the file in the tmp location is no longer there, and therefor cannot be removed, I would say.
Looking a bit harder at your code, consider a restructuring:
if(move_uploaded_file($fileTmpLoc, "Avatars/$fileName"))
{
// do the image stuff
}
else
{
echo "ERROR: An error occured uploading and storing your file. Please try again.";
// Add a test to see whether the file exists
unlink($fileTmpLoc); // Remove the uploaded file from the PHP temp folder
exit();
}
The regEx that you are using here
preg_match("/.(gif|jpg|png)$/i", $fileName)
is probably wrong. Because it will return true even for this file name $fileName="adjGIF" and i hope that you do not want this.So instead use this
preg_match("/.(\.(gif|jpg|png))$/i", $fileName)
Note:- Even though its not the answer but it will make your code correct.
//returns TRUE if the file or directory specified by filename exists and is readable, FALSE otherwise.
if (is_readable($fileTmpLoc)) {
unlink($fileTmpLoc);
}
use below code to move image file in to avatar named folder :
move_uploaded_file($fileTmpLoc,"Avatars".$fileName);
I was wondering if someone with more experience than me could take a quick second to have a look over my php script for uploading a file to my server.
I had a simple php script that uploaded my image the root of my server when I called the script in my code like so:
http://server.foo.com/images/uploadToDirectory.php
Now I'm trying to amend it so that I can put the name of a folder at the end with the following call:
http://server.foo.com/images/uploadToDirectory.php?dir=test_folder
But for some reason my image is only getting sent to the root of the server. I've checked the logic of my c# code so I think it must be something to do with my php script. Could someone please have a look over it and tell me if I'm doing something silly with my code?
<?
$_SESSION['directory'] = $_POST['directory'];
$uploaddir = './'.$_SESSION['directory'];
$file = basename($_FILES['file']['name']);
$uploadfile = $uploaddir . $file;
print_r($_FILES);
if (move_uploaded_file($_FILES['file']['tmp_name'], $uploadfile)) {
echo "http://server.ip.address/images/{$file}";
}
else
{
echo "Didn't Work!!!!";
}
?>
Please note, I know this is probably a really bad way for me to go about doing what I want to do, but it's the way I've implemented it. My knowledge of PHP isn't very good.
For comparison here is the code to load to the root of the server:
<?
$uploaddir = './';
$file = basename($_FILES['file']['name']);
$uploadfile = $uploaddir . $file;
print_r($_FILES);
if (move_uploaded_file($_FILES['file']['tmp_name'], $uploadfile)) {
echo "http://server.ip.address/images/{$file}";
}
else
{
echo "Didn't Work!!!!";
}
?>
Ok so.. if you invoke your script like this:
http://server.foo.com/images/uploadToDirectory.php?dir=test_folder
Then your script should be:
$uploaddir = './'.$_GET["dir"];
That would collect your URL GET variable "dir".
I am making an application that allows users to upload a file in a directory via PHP.
I am having problems because it dose not allow me to overwrite files with the same name.
Eg I have a file called text.php and I upload it, now when I go back and change the content of file text.php and I upload it again on the server I still have the version without the edits. However if I upload another file it works. So I just can't overwrite files.
if ($_POST["greg"]=='true'){
// Set local PHP vars from the POST vars sent from our form using the array
// of data that the $_FILES global variable contains for this uploaded file
$fileName = $_FILES["file1"]["name"]; // The file name
$fileTmpLoc = $_FILES["file1"]["tmp_name"]; // File in the PHP tmp folder
$fileType = $_FILES["file1"]["type"]; // The type of file it is
$fileSize = $_FILES["file1"]["size"]; // File size in bytes
$fileErrorMsg = $_FILES["file1"]["error"]; // 0 for false... and 1 for true
// Specific Error Handling if you need to run error checking
if (!$fileTmpLoc) { // if file not chosen
echo "ERROR: Please browse for a file before clicking the upload button.";
exit();
} else if($fileSize > 90000000000000) { // if file is larger than we want to allow
echo "ERROR: Your file was larger than 50kb in file size.";
unlink($fileTmpLoc);
exit();
} else if (!preg_match("/.(doc|docx|xls)$/i", $fileName) ) {
// This condition is only if you wish to allow uploading of specific file types
echo "ERROR: Your file is not the right format contact the master of the page for clarification.";
unlink($fileTmpLoc);
exit();
}
// Place it into your "uploads" folder mow using the move_uploaded_file() function
move_uploaded_file($fileTmpLoc, "documenti/$fileName");
// Check to make sure the uploaded file is in place where you want it
if (!file_exists("documenti/$fileName")) {
echo "ERROR: File not uploaded<br /><br />";
echo "Check folder permissions on the target uploads folder is 0755 or looser.<br /><br />";
echo "Check that your php.ini settings are set to allow over 2 MB files, they are 2MB by default.";
exit();
}
// Display things to the page so you can see what is happening for testing purposes
echo "The file named <strong>$fileName</strong> uploaded successfuly.<br /><br />";
echo "It is <strong>$fileSize</strong> bytes in size.<br /><br />";
echo "It is a <strong>$fileType</strong> type of file.<br /><br />";
echo "The Error Message output for this upload is: <br />$fileErrorMsg";
}
How can I change this code so that when I upload a file with the same name it overwrites the existing file?
Try this (put it before upload a file)
//checking if file exsists
if(file_exists("documenti/$fileName")) unlink("documenti/$fileName");
//Place it into your "uploads" folder mow using the move_uploaded_file() function
move_uploaded_file($fileTmpLoc, "documenti/$fileName");
Maybe the script does not have the rights to overwrite? Try to change the dir to 777 and test again. If it works then, you can figure out the correct value you need
if (file_exists("documenti/$fileName"))
{
unlink("documenti/$fileName");
echo "<font face='Verdana' size='2' >Last Uploaded File has been removed from uploads folder<br>back to uploadform agian and upload your file<br>";// now your file which uploaded before was deleted from uploads folder you can open it and check if it removed or not , so no you should go back to uploadform again and import your file which will uploaded correctly
echo "<font face='Verdana' size='2' ><BR><BR><BR><a href='upform.php'>Back to upform</a><BR>";
}
Have you tried checking if the file exists and deleting it if it does before you move the temporary file to the permanent storage location?
$filePathAndName = "documenti/$fileName";
//check file exists
if(file_exists($filePathAndName))
{
unlink($filePathAndName);
}
//move_uploaded_file() function
move_uploaded_file($fileTmpLoc, $filePathAndName);
i have this script but i want to rename the file:
<?php
$fieldname = $_REQUEST['fieldname'];
$uploaddir = 'uploads/';
$uploadfile = $uploaddir . basename($_FILES[$fieldname]['name']);
if (move_uploaded_file($_FILES[$fieldname]['tmp_name'], $uploadfile)) {
//i want to rename the file before i can upload it
echo $uploadfile; // "success"
}
else {
echo "error";
}
?>
how can i rename the file before i upload it to uploads/ directory!!
What ever you pass as the 2nd parameter to move_uploaded_file will be used as the file name.
The move_uploaded_file function does exactly that. When you are moving the uploaded file from the temporary location to the uploads/ directory, you can change the name of it.
move_uploaded_file($_FILES[$fieldname]['tmp_name'], 'uploads/whatever-i-want');
Just specify a different target name in $uploadfile.
