I am working on one web application where i upload one file using upload method in php and in the next page (upload.php), i process the data and display the content but i have one back button.
index.php
<!DOCTYPE html>
<html>
<body>
<form action="upload.php" method="post" enctype="multipart/form-data">
Select image to upload:
<input type="file" name="fileToUpload" id="fileToUpload">
<input type="submit" value="Upload Image" name="submit">
</form>
</body>
</html>
upload.php
<form action="process.php" method="post" enctype="multipart/form-data">
Select image to upload:
<input type="file" name="fileToUpload" id="fileToUpload">
<input type="submit" value="Upload Image" name="submit">
</form>
<?php
$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
// Check if image file is a actual image or fake image
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
echo "Sorry, your file was not uploaded.";
// if everything is ok, try to upload file
} else {
if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
} else {
echo "Sorry, there was an error uploading your file.";
}
}
?>
<form action="upload.php" method="post" enctype="multipart/form-data">
Select image to upload:
<input type="file" name="fileToUpload" id="fileToUpload">
<input type="submit" value="Upload Image" name="submit">
</form>
procees.php
<button onclick="goBack()">Go Back</button>
<script>
function goBack() {
window.history.back();
}
</script>
<?php
/*process uploaded file*/
?>
when i click Go Back button, again i need to upload the file, if there any way to remember the same file(which i uploaded) even though i go back?
Don't use window.history.back();
just redirect the user to the page you want him to go, and process the image before displaying the button, is good practice

Well pretty simple question.. But can't get it right for some reason.
What would be the html code to send a file to this?
move_uploaded_file($FILES["upload"]["tmpname"], $_POST["name"]);
Here's mine but when I used it and echo/vardump everything, I only have 'name' and not the file
<form action="uploader.php" method="post" id="myForm" enctype="multipart/form-data">
Select file to upload:
<input type="file" name="upload" id="upload">
<input type="text" name="name" id="name">
<button name="submit" class="btn btn-primary" type="submit" value="submit">Upload File</button>
</form>
Thank you
i try to add a comment but i can't
first check if upload permission is on in php.ini
file_uploads = On
If it set to on check your upload directory which you added in uploader.php file and use if to check $_FILES['upload'] is empty
this is a simple code to uploader.php file
<?php
if(!empty($_FILES['upload']))
{
$path = "upload/"; /// directory to upload
$path = $path . basename( $_FILES['upload']['name']);
if(move_uploaded_file($_FILES['upload']['tmp_name'], $path)) {
echo "The file ". basename( $_FILES['upload']['name']).
" has been uploaded";
} else{
echo "There was an error uploading the file, please try again!";
}
}else {
echo 'No file selected to upload ';
}
Recently I changed servers and my images uploading/resizing script (https://www.verot.net/php_class_upload.htm) stopped working, error message "Local file doesn't exist." The only change there was since it worked - I changed from $filetoUpload[$i] to $_FILES["fileToUpload"]["name"][$i].
Here's the script:
HTML
<form action="testupload.php" method="post" enctype="multipart/form-data">
Select image to upload:
<input type="file" name="fileToUpload[0]" id="fileToUpload">
<input type="file" name="fileToUpload[1]" id="fileToUpload">
<input type="submit" value="Upload Image" name="submit">
</form>
<?php
// testupload.php
include('classes/class.images.inc.php');
$pictureslocation = "my images location/";
for($i=0;$i<=1;$i++){
if($_FILES["fileToUpload"]["name"][$i] != "none" AND $_FILES["fileToUpload"]["name"][$i] != ""){
$handle =new upload($_FILES["fileToUpload"]["name"][$i]);
if ($handle->uploaded) {
// Script doesn't get here but gives an error
}else{
echo 'error : ' . $handle->error;
// The error it gives here is "Local file doesn't exist."
}
}
}
Just a simple upload script works without problems.
I need to upload a lot of images at once (e.g. 200 small images) through the browser. I have this code:
<?php
if(isset($_POST['Upload_files']) and $_SERVER['REQUEST_METHOD'] == "POST"){
echo count($_FILES['files']['name']); // Even if I upload more than 20 files, it still displays 20.
$target_directory = "upload/";
foreach ($_FILES['files']['name'] as $file_number => $file_name) {
$file = $_FILES["files"]["tmp_name"][$file_number];
if (mime_content_type($file) != 'image/png' && mime_content_type($file) != 'image/jpeg')
{ $error[] = 'File '.$file_name.' is not in JPG / PNG format!'; continue; }
else
{ if(move_uploaded_file($file, $target_directory.$file_name)) {$count_of_upload_file++;}}
}
}
// If files were uploaded
if($count_of_upload_file != 0){echo 'Your files ('.$count_of_upload_file.' ) were successfully uploaded.';}
// If there was an error
if (isset($error)) {foreach ($error as $display_error) {echo '- '.$display_error.'<br />';}}
?>
<form action="" method="post" enctype="multipart/form-data">
<input type="file" name="files[]" multiple="multiple" accept="image/*">
<input type="submit" name="Upload_files" value="Upload files">
</form>
And it works. However my provider set the 'max_file_uploads' to 20 (and I'm not able to change it). (The Uploadify extension is working for more than 20 files, but I'd like to have my own small solution.) So I presume I need to add here something, which instead of 200 files at once uploads 200 files one by one (or twenty by twenty). But I don't know how to do it. (To use AJAX? -- I never used it, so I really don't know.) Thank you!
If you don't want to use ajax, you need a loop to receive files
for($i = 0; $i < count($_FILES['files']['tmp_name']); $i++){
$tmp = $_FILES['files']['tmp_name'][$i];
$name = md5(microtime());
if(move_uploaded_file($tmp, "dir/$name.jpg")){
echo "Uploaded successfully";
}else{
echo "failed";
}
}
In your form you must name all your input fields as files[], example:
<form action="" method="post" enctype="multipart/form-data">
<input type="file" name="files[]" multiple="multiple" accept="image/*">
<input type="file" name="files[]" multiple="multiple" accept="image/*">
<input type="file" name="files[]" multiple="multiple" accept="image/*">
<input type="submit" name="Upload_files" value="Upload files">
</form>
Or if you want to use ajax here is an example:
Upload multiple image using AJAX, PHP and jQuery
I have have 2 files. one for image upload. one for evaluating.
1st file:
<html>
<head><title>Upload File</title></head>
<body>
<h2>Upload File</h2>
<form method="post" action="Assignment7_backend.php" enctype="multipart/formdata"><input type='hidden' name='MAX_FILE_SIZE' value='50000'>
Your file: <input type="file" name="image">
<br/>
<input type="submit" value="Send it!">
</form>
</body>
</html>
2nd file:
<html>
<head><title>Upload File</title></head>
<body>
<h2>Upload File now</h2>
<?php
if (is_uploaded_file($_FILES['image']['tmp_name'])) {
if($_FILES['image']['error'] != UPLOAD_ERR_OK) {
print "<p>File not uploaded successfully!</p>";
print "<p><a href='Assignment7_upload.php'>Try Uploading Again</a> </p>" ;
} else {
move_uploaded_file($_FILES['image']['tmp_name'], "./images/" . $_FILES['image']['name'] )
or die("can't move file");
print "<p>Success!</p>";
}
} else {
print("<p>File is not uploaded</p>");
print("<p>".$_FILES['image']['error']."</p>");
if (!isset($_POST['submit'])) {
print("<p>cannot even detect submit</p>");
}
}
?>
</body>
</html>
I was hoping to upload the file, but after I choose the file and submit, it shows error: $_FILE['image'] index is undefined. also, $_POST['submit'] is not set. what is wrong with my code?
The enctype you posted here is wrong. So the form fails to submit any image/file.
I don't know if this is a typo or you actually have it wrong in your code.
The correct one is: enctype="multipart/form-data"
The code
<?php
$allowed_filetypes = array('.jpg','.gif','.bmp','.png');
$max_filesize = 5242888;
$upload_path = '/files';
$filename =$_FILES['userfile']['name'];
$ext = substr($filename,strpos($filename,'.'),strlen($filename)-1); //Get the extension form the filename.
if(!in_array($ext,$allowed_filetypes))
die('the file you attempted to upload is not allowed.');
if(filesize($_FILES['userfile']['size'])>$max_filesize)
die('the file you attempted to upload is too large.');
if(!is_writable($upload_path)) {
die('you cannot upload to the specified directory,please CHMOD it to 777.');
}
if (move_uploaded_file( $_FILES['userfile']['tmp_name'],$upload_path.$filename))
{
echo 'you file upload successful.view the file here';
}
else{
echo 'failed';
}
When I upload a JPEG image, it shows the error "The file you attempted to upload is not allowed.". What's wrong with my code?
The main HTML code:
<form action="upload.php" method="post" enctype="multipart/form-data">
<input type="file" name="userfile" id="file"/>
<button>upload</button>
Please use in form tag
<form action="upload.php" method="post" enctype="multipart/form-data">
Try replace:
$ext = substr($filename,strpos($filename,'.'),strlen($filename)-1);
//get the extension form the filename
by
$ext = substr($filename,strpos($filename,'.'),4);
//get the extension form the filename
<form action="upload.php" method="post" enctype="multipart/form-data">
<input type="file" name="userfile" id="file"/>
<input type="submit" name="sendFile" value="Upload" />
</form>
that should work.
Try with a submit button, <input type="submit " name="upload" value="upload"/>.
