How to upload default image file in folder PHP? I am trying to upload selected file or default file in particular folder, but I can't make good.
target_file = $target_dir . time()."_abc.jpg";
or
basename($_FILES["files"]["name"]="abc.jpg";
You cannot upload directly by using the filename. Every file has a temporary path where it is stored when it is uploaded. this is referred to by tmp_name. You'll have to upload this tmp_name to the specific directory. Consider below code:
$target_file = $target_dir . time()."_abc.jpg";
if (file_exists($target_file)) {
if (move_uploaded_file($_FILES['files']['tmp_name'], $target_file)) {
echo "File Uploaded";
} else {
echo "File Not Uploaded";
}
}
Hope this helps.
Its not clear about the scenario in which you are trying to upload default file or selected file. Generally if one selected a file then only the need to upload the file arises otherwise you just keep a default file in folder and show that. If you are concerned about file uploads in php,
you need to follow certain procedures to upload files into folder using any programming language. For the case of PHP first need to check in php.ini whether
file_uploads = On if it is On then you can proceed for file uploading. The form should enable enctype to enctype="multipart/form-data"
Next you can restrict the image format that is to be uploaded, image size etc based on different php functions belong to $_FILES variable.

I'm following a tutorial for uploading image files using php on udemy. I can choose an image and upload it to a folder without any problems.
When I click on the image after it has been uploaded to the folder, windows photo viewer says: "photo.png It appears that you don't have permission to view this file. Check the permissions and try again".
When I checked permissions it said "You must have read permissions to view the properties of this file".
I used the chmod function set to 0755, which allows the owner to read and write, and lets everyone else read it. I tried changing the chmod codes but it didn't help.
I'm thinking it has something to do with my server permissions, but can't find any solution on google. My images are uploaded to Abyss Web Server.
Here is the code:
<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);
function upload_file() {
//setup
$tmp_name = $_FILES['file']['tmp_name'];
$target_dir = 'uploads/';
$target_file = $target_dir . basename($_FILES['file']['name']);
$max_file_size = 5000000; //5mb
$allowed_file_types = array('application/pdf; charset=binary');
$allowed_image_types = array(IMAGETYPE_GIF, IMAGETYPE_JPEG, IMAGETYPE_PNG);
//check if image type is allowed
$image_check = getimagesize($tmp_name);
if(! in_array($image_check[2], $allowed_image_types)) {
//if not allowed image check if allowed file type
exec('file -bi' . $tmp_name, $file_check);
if(! in_array($file_check[0], $allowed_file_types)) {
return 'This file type is not allowed';
}
}
//check if file already exists
if(file_exists($target_file)) {
return 'Sorry that file already exists';
}
//check file size
if(file_exists($target_file)) {
return 'Sorry this file is too big';
}
//store the file
if(move_uploaded_file($tmp_name, $target_file)) {
chmod($target_file, 0644);
return 'Your file was uploaded';
}
else {
return 'There was a problem storing your file. Try again?';
}
}
if(! empty($_FILES)) {
echo upload_file();
}
?>
<form action="" method="post" enctype="multipart/form-data">
Select image to upload:
<input type="file" name="file">
<input type="submit" Value="upload">
</form>
Since loading the file using a custom made HTML page specifically for testing motives does show the image correctly, then it's most likely a hotlink protection issue. (This was found out after a few comments to the question).
In cPanel, for example, there is a tool to manage this feature and it revolves around the usage of a file called .htaccess. This file is used for a lot of things in the web development world.
Some people don't like their copyrighted images to be accessed, so one way to avoid inexperienced people (let's say, "people in userland") from doing that is to enable this protection. This works for any given file extension that you set it up to.
One way to address this issue is to go to cPanel and disable (or modify accordingly) the Hotlink Protection feature. Another way, is to find the .htaccess file that is causing the issue, which requires understanding the way it works and the syntax it uses.
I am completely a novice in all this ...
I have created a Social Networking project in which there is a module which allows user to upload photos..
I have hosted this project in my college server
I access that server using bitvise client with my server credentials.
My problem is i don't know how to setup upload mechanism for remote server ... In my localhost i simply use
move_uploaded_file($_FILES['file']['tmp_name'],$target_file);
function but i don't know how to do this for remote server ...
I tried FTP by looking at some tutorials but that didn't worked for me.
In my project structure there is a directory
users/user_id (diff for all users)/photos
here i want to place the uploaded files....
A proper description with example and proper functioning might be very helpful for me.... Thank you
EDIT:
Below is my code.
Photos.php
<form class="input-group-btn" method="post" action="editPhotos.php"enctype="multipart/form-data" id="myForm">
<input type="file" name="file" id="imgInp">
<button type="submit" class="btn btn-primary" name="form-submit">Done</button>
</form>
editPhotos.php
if( isset($_POST['form-submit']) ){
$target_file = "users/".$email."/pictures/Photos/" . basename($_FILES["file"]["name"]);
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
move_uploaded_file($_FILES['file']['tmp_name'],$target_file);
$img =str_replace(" ", "",basename($_FILES["file"]["name"]));
rename($target_file, "users/".$email."/pictures/Photos/".$img);
header('Refresh: 1; url=Photos.php?user='.$email);
}
Small tutorial how to upload file.
For sure, you need correct encryption and file's type in your form (ommited other fields, to clear example):
form.html
< form action="upload.php" method="post" enctype="multipart/form-data">< /form>
< input name="test" type=file>
upload.php
In $_FILES you have all data of uploaded file. In given example, we have field named test.
Advice, to always first check error $_FILES['test']['error'] - the values you can find in here.
If this is correct, then prepare upload path. Some advices:
remember that if you use original filename ($_FILES['test']['name']), then is User upload second file, with same name, you will need overwrite file or ignore upload. Other way, is to save data to database and generate temporary name form him.
destination path(target_file) - regardless if upload folder is in the same catalog, you should always use global path, as good practice. You can use DIR for that.
don't use in path data, like email - is you have project, and want give opportunity to change email in configuration, what you will do with files? Better save user to Database and use his ID as key.
If you have path, then you simply need only use of move_uploaded_file, but remember to check result, as it not always will return true. You can have error, when you don't have permissions to destination folder (you'll need debug this).
I see that you, first upload file, then rename (then you should check, if rename was success). Don't extends this process, if it not necessary. Upload file for final path and name.
Example of code (I this rattle off)
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
$email = filter_var($_POST['email'], FILTER_VALIDATE_EMAIL);
$fileName = basename($_FILES["file"]["name"]);
$fileName = str_replace(" ", "", $fileName);
$target_file = sprintf(__DIR__ . "/users/%s/pictures/Photos/%s", $email, $fileName);
if (move_uploaded_file($_FILES['file']['tmp_name'], $target_file)) {
// File was uploaded
header('Refresh: 1; url=Photos.php?user=' . $email);
} else {
// File was not uploaded;
throw new \Exception('File was not uploaded. Check warnings.');
}
}
Used other method to check, if this is POST
use method sprintf, for better code quality
checked effect of move_uploaded_file
use global path for destination file
Below code is risky in live environment, please use cautiously
Use a relative path to the uploads folder. For example, if your uploads folder is placed outside your current folder. Then
$PATH = '/absolute/example/path/to/uploads';//from config file
$target_file = "$PATH/file_name";
move_uploaded_file($_FILES['file']['tmp_name'],$target_file);
The above code will work both in local and remote server.
Other checks are below:
Check for errors while uploading file in server
To enable error handling use below code in your upload logic:
ini_set('display_errors', 1);
error_reporting(E_ALL);
Another important note is to make uploads folder writable otherwise file upload wont work.
I am having a problem with move_uploaded_file().
I am trying to upload a image path to a database, which is working perfectly and everything is being uploaded and stored into the database correctly.
However, for some reason the move_uploaded_file is not working at all, it does not produce the file in the directory where I want it to, in fact it doesn't produce any file at all.
The file uploaded in the form has a name of leftfileToUpload and this is the current code I am using.
$filetemp = $_FILES['leftfileToUpload']['tmp_name'];
$filename = $_FILES['leftfileToUpload']['name'];
$filetype = $_FILES['leftfileToUpload']['type'];
$filepath = "business-ads/".$filename;
This is the code for moving the uploaded file.
move_uploaded_file($filetemp, $filepath);
Thanks in advance
Try this
$target_dir = "business-ads/";
$filepath = $target_dir . basename($_FILES["leftfileToUpload"]["name"]);
move_uploaded_file($_FILES["leftfileToUpload"]["tmp_name"], $filepath)
Reference - click here
Try using the real path to the directory you wish to upload to.
For instance "/var/www/html/website/business-ads/".$filename
Also make sure the web server has write access to the folder.
You need to check following details :
1) Check your directory "business-ads" exist or not.
2) Check your directory "business-ads" has permission to write files.
You need to give permission to write in that folder.
make sure that your given path is correct in respect to your current file path.
you may use.
if (is_dir("business-ads"))
{
move_uploaded_file($filetemp, $filepath);
} else {
die('directory not found.');
}
Got the server, got the domain, got the code, getting the images successfully, making the products for the customers from the image files they upload. Yay!
Problem: all my image names are image_0001 etc.
Customers can't rename image files from iPhones and do not care to from PCs.
So I was thinking about putting a short form on the upload page asking for customer's last name and having the PHP code attach that name to the image file(s) being uploaded.
If it's not possible, I'm sorry for the inconvenience.
You can rename files after they have been saved to your server, check out the PHP manual for the rename function - http://www.php.net/manual/en/function.rename.php, or just while you are moving them from the tmp directory, you can specify a different name for the uploaded file. See http://www.php.net/manual/en/function.move-uploaded-file.php
Be careful to include something in your code for dealing with naming conflicts.
This one might help :
$imagename = basename($_FILES['file']['name']);
$ext = pathinfo($imagename , PATHINFO_EXTENSION); //we want to change the file name but not the extension
$newImagename= $imageName.$username.'.'.$ext; //assuming you hold the username in $username
if (move_uploaded_file($_FILES['file']['tmp_name'], "/path/{$newImagename}"))
{
....
}
I have searched far and wide on this one, but haven't really found a solution.
Got a client that wants music on their site (yea yea, I know..). The flash player grabs the single file called song.mp3 and plays it.
Well, I am trying to get functionality as to be able to have the client upload their own new song if they ever want to change it.
So basically, the script needs to allow them to upload the file, THEN overwrite the old file with the new one. Basically, making sure the filename of song.mp3 stays intact.
I am thinking I will need to use PHP to
1) upload the file
2) delete the original song.mp3
3) rename the new file upload to song.mp3
Does that seem right? Or is there a simpler way of doing this? Thanks in advance!
EDIT: I impimented UPLOADIFY and am able to use
'onAllComplete' : function(event,data) {
alert(data.filesUploaded + ' files uploaded successfully!');
}
I am just not sure how to point THAT to a PHP file....
'onAllComplete' : function() {
'aphpfile.php'
}
???? lol
a standard form will suffice for the upload just remember to include the mime in the form. then you can use $_FILES[''] to reference the file.
then you can check for the filename provided and see if it exists in the file system using file_exists() check for the file name OR if you don't need to keep the old file, you can use perform the file move and overwrite the old one with the new from the temporary directory
<?PHP
// this assumes that the upload form calls the form file field "myupload"
$name = $_FILES['myupload']['name'];
$type = $_FILES['myupload']['type'];
$size = $_FILES['myupload']['size'];
$tmp = $_FILES['myupload']['tmp_name'];
$error = $_FILES['myupload']['error'];
$savepath = '/yourserverpath/';
$filelocation = $svaepath.$name.".".$type;
// This won't upload if there was an error or if the file exists, hence the check
if (!file_exists($filelocation) && $error == 0) {
// echo "The file $filename exists";
// This will overwrite even if the file exists
move_uploaded_file($tmp, $filelocation);
}
// OR just leave out the "file_exists()" and check for the error,
// an if statement either way
?>
try this piece of code for upload and replace file
if(file_exists($newfilename)){
unlink($newfilename);
}
move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $newfilename);
