I am uploading an image using an HTML form.
When I get the full path to the image, it outputs something like this:
'/tmp/phpkIv1BY/10259944_770025219687938_1184503840380306483_n.jpg'
but when I go to the /tmp folder, the sub-folder phpkIv1BY doesn't even exist! What's going on here?
Reason for this behaviour
All uploaded files are temporarily stored in the folder location as defined in
(In php.ini)
upload_tmp_dir =
(Read more about this: http://php.net/upload-tmp-dir)
These temporarily stored files are no longer exist after that php script execution(As mentioned in previous answer request life span) finished.
Do the following to view uploaded file while script executing.
upload.html
<html>
<body>
<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>
</body>
</html>
upload_file.php
<?php
if ($_FILES["file"]["error"] > 0) {
echo "Error: " . $_FILES["file"]["error"] . "<br>";
} else {
$fp=fopen("/tmp/write.log","w+");
fputs($fp,"Original Name:".$_FILES["file"]["name"].";temporay Name:".$_FILES["file"]["tmp_name"]."\n");
fclose($fp);
sleep(50000);
}
?>
Upload file by upload.html
In another terminal apply tail in /tmp/write.log after uploading image(Because sleep time is too much so you able to find the image)
#tail -f /tmp/write.log
Copy that temporary file into any place and place the extension of original image file
For example my printed log line is
Original Name:digits.png;temporay Name:/tmp/phpOKlpoK
(Needed to do this with root privilages)
#cp /tmp/phpOKlpoK /home/sandeep/Desktop/file.png
#chown sandeep.sandeep /home/sandeep/Desktop/file.png
So this is the uploaded file that you.
(
Instead of doing all these steps for checking uploaded images you can use move_uploaded_file()
)
I can not find anywhere if PHP might create a temporary folder for temporary uploaded files. But what is certain is that uploaded files are kept temporary and as soon as the request is done, they are removed. So if you think you can find some uploaded file in the /tmp folder, think again.
If you would like some uploaded file to live longer than a request life span, then you need to move it somewhere safe using move_uploaded_file().

I'm trying to write code in php so that when the .php file is opened, it automatically uploads from a specific file address on my windows computer to the localhost server.
This is my attempt but I'm not sure I fully understand how to do this without using an HTML form where the user specifies the file they want to upload.
<?php
$target = 'UPLOADED_FILE.csv';
move_uploaded_file('C:\Users\Ken.Feier\Desktop\temp\REPORT.csv', $target);
?>
I want the code to take the REPORT.csv file from my personal computer and upload it to our server with the file name UPLOADED_FILE.csv
UPDATE: I see that my problem will not be solved with php. Can anyone recommend any other solution involving Filezilla or any other FTP that can be automated?
That's not how it should be done.
You need a page with a html form, which will send the data to server on submit. Note that the file could be stored on your personal.
Form code e.g.
<form method="post" action="destination.php" enctype="multipart/form-data">
<input type="file" name="filename" />
<input type="submit" value="upload" />
</form>
Then, on the server, you can use the $_FILES['filename'] which contains your file's infos. Note that when a file is uploaded to the server, it's stored in the tmp folder, which is temporary, so you have to move your file to a persistent directory with move_uploaded_file(); (move_uploaded_file Docs)
E.g:
<?php
$file = $_FILES['filename'];
move_uploaded_file($file['tmp_name'], '/new/destination/for/the/filename.php');
I've got the following code to upload a file and add it to the folder called images located in the root of the server.
$file = $_FILES['prodImg']['tmp_name'];
$newLoc="/images/" . $_FILES['prodImg']['name'];
if(move_uploaded_file($file, $newLoc)){
//do some other code here
}
else{
echo 'error';
}
the form has this button to add the image
<input type="file" name="prodImg" id="prodImg" accept="image/png" />
the images folder has all permissions set to read, write and execute
every time i try to upload an image it go to the else statement.
not sure what i'm doing wrong here.how do i make it work properly?
Do you have attribute in your form?
enctype="multipart/form-data"
I.e.:
<form action="..." method="post" enctype="multipart/form-data">
Then you can try to check permission for that folder.
And also try change filepath:
$newLoc="./images/" . $_FILES['prodImg']['name'];
or
$newLoc="images/" . $_FILES['prodImg']['name'];
The path of your $newLoc variable may be wrong. Try ./images/.
The one specified may define an image folder on the same level as the home, root... folders if you use Linux.
remove the slash ahead of images
$newLoc= "images/".$_FILES['prodImg']['name'];
Failed to upload file using HTML form:
after I click the submit botton, I could print out the $_FILES["file"]["name"] and $_FILES["file"]["type"] and ["size"] and ["tmp_name"] and
["error"] and etc.but I could not find the file in the tmp folder(it should be there by default)!I don't know why.
the html code goes like this:
<form action="manage.php?act=getback.questionOpt" target="fileUp" method="post" id="f1" enctype="multipart/form-data">
<p id="file_u">
<input type="file" name="file">
<iframe width="0px" height="0px" name="fileUp" style="display:none">
</iframe>
</p>
</form>
Uploaded files are deleted from the temp-directory unless they are moved or renamed!
There is a small note about that just above the third example on the PHP-Documentation at http://de2.php.net/manual/en/features.file-upload.post-method.php
Therefore you will not be able to see the file after the request is finished.
Simply renaming the file should do the trick.
How big is your file? If it is too big and exceeds your server limit, it won't upload. If your server has uploading disabled by default, you will need to turn it on in php.ini. This is how:
Open the php.ini file in your editor.
Search for the text string file_uploads. You will find something which says file_uploads = Off | On. If it says Off as the value, problem solved. Otherwise, it could be commented (check for semicolon at start of line). Otherwise:
Change the file permissions of your tmp folder.
Unless you show us the full code, there is nothing else I can do to help you.
I have an assignment for school, and I'm not sure how the teacher wants us to accomplish a task.
We need to get an uploaded file as a temp file only (index.php)
Output size of file (upload.php)
User can confirm save of file or not (upload.php)
So, I have the majority down, but my problem lies with creating the temp file into a permanent file.
index.php
<html>
<form action="http://mysite.org/~me/upload.php" method="POST" enctype="multipart/form-data">
<input type="file" name="file"><br />
<input type="submit" value="Now upload it!">
</form>
</html>
upload.php
<?php
if (($_FILES["file"]["type"] == "application/vnd.ms-excel"))
{
if ($_FILES["file"]["error"] > 0)
{
echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
}
else
{
echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
}
}
?>
<form action="" method="POST">
<input type="submit" value"YES please save">
<form>
<?php
if (isset($_POST['submit']))
{
//Code for saving file
echo 'File saved!';
}
?>
Is it possible to go about it this way? My last echo statement does not work, so I'm doubtful the file save would be as well.
Hopefully the following comments can help you with the part you are stuck on.
In case you hadn't realized it already, any files uploaded with PHP are deleted once the PHP request that handled the uploaded file terminates. This means, if you don't do anything with the temp file from the upload, it will be deleted when the PHP script terminates.
One function of interest to you will be move_uploaded_file() which will move the temporary file from the upload to a permanent location of your choice.
Since the file will be uploaded and then you have to display the size and ask the user to confirm the upload, you will have to move the temp file to a permanent temporary location where it is kept when the user hasn't confirmed they want to keep the upload.
I'm not sure if you have been introduced to sessions yet, but if not, you will probably need some hidden form element that will keep track of what file they uploaded, otherwise you can keep this info in the session.
Then when the person submits the form saying they want to keep the file, you can move it again to a permanent location, or if they say no, then delete the file. The problem is, if they never say yes or no, then the file remains on the system.
Hope that helps.
Yep, this should work. Your if statements will catch the form submission and then echo your string there. A few little errors in your markup:
<input type="submit" value"YES please save">
Should be
<input type="submit" value="YES please save" name="submit">
Your final if statement in PHP is looking for a post variable named 'submit' but your <input type="submit"> tag has no name.
The file is saved to a temporary location when the upload completes. You can access this temporary file with $_FILES['file]['tmp_name'] BUT the file will be removed at the end of the request if you do nothing about it. This means that when the user clicks YES please save button, the file will not be available any more.
This means that you have to save the file to a disk in the first place, when you first call the upload.php file. There is no way to keep the file "in memory" while the user decides whether or not to save the file permanently.
I have had problems with a simple php script in which I can upload a file to a certain folder. I have tried multiple ways in doing this and I still have not had success.
Any errors in my code or advice on how to correct the issue will be taken gracefully.
Main Php Code:
<p>Browse For a File on your computer to upload it!</p>
<form enctype="multipart/form-data" action="upload_photos.php" method="POST">
Choose Photo:
<input name="userfile" type="file" /><br />
<input type="submit" value="Upload Photo" />
<?PHP
if ($userfile_size>250000)
{$msg=$msg."Your uploaded file size is more than 250KB so please reduce the file size and then upload.<BR>";
$file_upload="false";}
else{
if (!($userfile_type<>"image/jpeg" OR $userfile_type<>"image/tiff" OR $userfile_type<>"image/png"))
{$msg=$msg."Your uploaded file must be of JPG, PNG, or tiff. Other file types are not allowed<BR>";
$file_upload="false";}
}
?>
</form>
</label>
</form>
Php code that is called upon on click (upload_photos.php)
<?php
$target_path="uploads/";
chmod("uploads/", 0755);
$target_path=$target_path . basename( $_FILES['uploadedfile']['name']);
$test=move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path);
if($test) {
echo "The file ". basename( $_FILES['uploadedfile']['name']).
" has been uploaded";
} else{
echo "There was an error uploading the file, please try again!";
var_dump($test);
}
?>
I do not understand why my end results [upon clicking "Upload Files" Button] include only the following results:
"There was an error uploading the file, please try again!bool(false)"
One more thing: I have also tried using the full computer folder path for $target_path and chmod.
Does anybody see what I am doing wrong?
You have <input name="userfile" but then use $_FILES['uploadedfile'] in your script - use one or the other.
Other than that, make sure the chmod worked and the folder is writable.
bool(false) is the output of var_dump($test);, indicating that move_uploaded_file is returning false.
As a basic debugging step, you should try var_dump($_FILES) to make sure you're accessing the right element of that array (I can tell from your code that you aren't, the index will be the name attribute of your <input type="file"/> element).
You have at least one other serious flaw in your logic... The PHP code in your upload form doesn't make any sense. That block of PHP code will execute server-side before the user has ever uploaded a file. It can't possibly work. The two variables you're checking, $userfile_size and $userfile_type, are not defined anywhere.
In my case, I forgot to create a folder where I want to upload. So check once the specified upload path is available or not.
