I am using some jquery to help upload a file to a php script. Everything is working fine and the file does in fact get uploaded. But during the upload, I have made it so the file gets resized to our needs, with a new unique file name. I'd like to pass that new unique file name back to the jquery and have it display on the page. Right now, it just displays the original image (which is not resized)
Here's the jquery code:
$(function(){
var btnUpload=$('#upload');
var status=$('#status');
new AjaxUpload(btnUpload, {
action: 'upload-file.php',
name: 'uploadfile',
onSubmit: function(file, ext){
if (! (ext && /^(jpg|png|jpeg|gif)$/.test(ext))){
// extension is not allowed
status.text('Only JPG, PNG or GIF files are allowed');
return false;
}
status.text('Uploading...');
},
onComplete: function(file, response){
//On completion clear the status
status.text('');
//Add uploaded file to list
if(response==="success"){
$('<li></li>').appendTo('#files').html('<img src="./uploads/'+file+'" alt="" /><br />'+file).addClass('success');
} else{
$('<li></li>').appendTo('#files').text(file).addClass('error');
}
}
});
});
And then my upload php file looks like this:
$uploaddir = 'uploads';
$file = $uploaddir . basename($_FILES['uploadfile']['name']);
if (move_uploaded_file($_FILES['uploadfile']['tmp_name'], $file)) {
$path = realpath(dirname(__FILE__));
include $path . '/uploads/phmagick.php';
$temp_file = explode(".", $_FILES['uploadfile']['name']);
$time = time();
$new_file = $time . '.' . $temp_file[1];
$p = new phmagick($path . '/uploads/' . $_FILES['uploadfile']['name'], $path . '/uploads/' . $new_file);
$p->convert();
$phMagick = new phMagick($path . '/uploads/' . $new_file, $path . '/uploads/' . $new_file);
$phMagick->debug=true;
$phMagick->resize(414,414,true);
echo "success";
} else {
echo "error";
}
Any thoughts on how I can get the new unique file name back, which would be something like: 1397413326.jpg?
Thank you
Echo the filename back instead of the word "success".

I have this code from this reference https://github.com/jhuckaby/webcamjs/blob/master/DOCS.md?fbclid=IwAR0Q3W5mw8qWlJEdiabmyZJiw7wGJ5YDPRl2Ej0IKF3GCt_78HXeqAEjI6Y
it will display the webcam and take snapshots and make it to an image element using the data_uri but the problem is I want to get that file and store it with a declared filename into a folder here's the script I use
<script src="webcam.js"></script> <!--source code script from github for webcam config-->
<div id="my_camera" style="width:320px; height:240px;"></div>
<div id="my_result"></div>
<script type=text/javascript>
Webcam.attach( '#my_camera' );
function take_snapshot() {
Webcam.snap( function(data_uri) {
document.getElementById('my_result').innerHTML = '<img src="'+data_uri+'"/>';
} );
}
</script>
Take Snapshot
I have a button called register that functions like get all information being input and store it into the database like username first name etc together with the image taken by snapshot, here's my upload script in uploading images from a folder and I want to use it as getting the image data_uri and store it in a folder when I click the register button
<?php
session_start();
include_once'database.php';
$uid = $_SESSION['u_id'];
if (isset($_POST['submit'])){
$file = $_FILES['file'];
$fileName = $_FILES['file']['name'];
$fileTmpName = $_FILES['file']['tmp_name'];
$fileSize = $_FILES['file']['size'];
$fileError = $_FILES['file']['error'];
$fileType = $_FILES['file']['type'];
$fileExt = explode('.', $fileName);
$fileActualExt = strtolower(end($fileExt));
$allowed = array('jpg', 'jpeg', 'png');
//check if ang uploaded file allowed i upload//
if (in_array($fileActualExt, $allowed)){
if ($fileError == 0){
if ($fileSize < 1000000){
$fileNameNew = "profile".$uid.".".$fileActualExt;
$fileDestination = 'uploads/'.$fileNameNew;
move_uploaded_file($fileTmpName, $fileDestination);
$sql = "UPDATE profileimg SET status=0 WHERE userID ='$uid';";
$result = mysqli_query($conn, $sql);
header("location:../pages/userpage.php");
}
else {
echo "Your file is too big";
}
} else {
echo "There was an error uploading you file!";
}
} else {
echo "You cannot upload files of this type";
}
}
I'm going to use this function as stated in the documentation
Webcam.upload( data_uri, 'myscript.php', function(code, text) {
// Upload complete!
// 'code' will be the HTTP response code from the server, e.g. 200
// 'text' will be the raw response content
} );
} );
and have this in my php script
move_uploaded_file($_FILES['webcam']['tmp_name'], 'webcam.jpg');
any idea how should I turn this script into the one I use above in my upload.php? thanks in advance
You need to create image first by image src and then need to save that in a specific folder. You can follow below code:
file_put_contents("fileNameWithLocation.png",file_get_contents($imageSrc));
Here fileNameWithLocation.png will be $fileNameNew = "profile".$uid.".".$fileActualExt; $fileDestination = 'uploads/'.$fileNameNew; You need to make modification accordingly. And $imageSrc will be the image src which you can post via Ajax or form submission.
Hope it helps you.
I have a self destruct PHP code that would delete all files and folders in my domain's directory.
<?Php
$dir = 'C:\wamp64\www\FileDirectory' . DIRECTORY_SEPARATOR . 'Files';
$it = new RecursiveDirectoryIterator($dir, RecursiveDirectoryIterator::SKIP_DOTS);
$files = new RecursiveIteratorIterator($it, RecursiveIteratorIterator::CHILD_FIRST);
foreach($files as $file) {
if ($file->isDir()){
rmdir($file->getRealPath());
} else {
unlink($file->getRealPath());
}
}
rmdir($dir);
$filename = 'C:\wamp64\www\FileDirectory\Files';
if (file_exists($filename)) {
echo "The Directory has not been deleted";
} else {
echo "All Files And Folders Are Deleted";
}
?>
I need a way to only activate this code when I type in extra code to the end of my URL. I thought you could do that with JavaScript but I'm not too certain. Please let me know if I can do this. If I have to use a different code to do so, it's not a big deal.
Use $_GET['parameter'] to get parameter from get method:
http://example.com/index.php?doClean=1
if (isset($_GET['doClean'])) {
// Your code goes here
}
So, I looked up a tutorial for uploading and sending files to a server with an XML HTTP Request. I followed the tutorial, however, I think I must be missing something. While the file appears to be uploaded and sent, nothing in the "handler" file is ever accessed. Is there a PHP function I need to write to process it? For context, here is what I wrote:
$(document).ready(function()
{
$('#upload-button').click(function(event)
{
$('#upload-button').removeClass("btn-danger");
});
$( "#report-form" ).submit(function( event )
{
var form = document.getElementById('report-form');
var fileSelect = document.getElementById('file-select');
var uploadButton = document.getElementById('upload-button');
event.preventDefault(); // Stop the event from sending the way it usually does.
uploadButton.value = 'Submitting...'; // Change text.
var files = fileSelect.files;
var maxfiles = <?php echo $config['Report_MaxFiles'] ?>;
var mfs = <?php echo $config['Report_MaxFileSize'] ?>;
if(files.length > maxfiles) // Make sure it's not uploading too many.
{
uploadButton.value = 'You uploaded too many files. The limit is ' + maxfiles + '.'; // Update button text.
$('#upload-button').addClass('btn-danger'); // Make the button red, if so.
return;
}
var formData = new FormData(); // Make a "form data" variable.
for (var i = 0; i < files.length; i++) {
var file = files[i];
// Add the file to the request.
if(file.size / 1000 > mfs)
{
uploadButton.value = 'One of the files is too big. The file size limit is ' + (mfs) + 'kb (' + (mfs / 1000) + 'mb).';
$('#upload-button').addClass('btn-danger');
return;
}
formData.append('files[]', file, file.name); // Not really sure what this does, to be honest,
// but I think it makes a file array.
}
var xhr = new XMLHttpRequest(); // Construct an XML HTTP Request
xhr.open('POST', 'assets/class/FileHandler.php', true); // Open a connection with my handler PHP file.
xhr.onload = function ()
{
if (xhr.status === 200)
{
uploadButton.value = 'Files Submitted!'; // NOTE: I do get this message.
}
else
{
uploadButton.value = 'An error occurred.';
$('#upload-button').addClass("btn-danger");
}
};
xhr.send(formData); // I think this is where it dies.
});
});
At the "send(formData)" line, I'm not actually sure if it's sending. Do I set up some sort of listener in FileHandler.php that is activated when the files are sent via XML HTTP request? Or more specifically, how to I save the uploaded files to the server using my FileHandler.php file?
EDIT: I haven't been able to come up with any other PHP code in the FileHandler.php file than this, which I thought might be called when the form is sent (but it isn't):
EDIT 2: Okay, now I have something, but it isn't working (didn't expect it to). I think I may be using the variables wrong:
<?php
$uploaddir = 'data/reports/uploads/' . $_POST['id'] . "/";
$uploadfile = $uploaddir . basename($_FILES['files']['name']);
echo "<script>console.log('RECEIVED');</script>";
echo '<pre>';
if (move_uploaded_file($_FILES['files']['tmp_name'], $uploadfile)) {
echo "File is valid, and was successfully uploaded.\n";
} else {
echo "Possible file upload attack!\n";
}
echo 'Here is some more debugging info:';
print_r($_FILES);
print "</pre>";
It's not saving the file to the directory, nor is it printing the script message. How do I get my report.php file to execute these things in FileHandler.php?
Thanks to the help and patience of #Florian Lefèvre, I got it fixed. :)
The problem was with the path. It wasn't locating the path to the folder data/uploads/ and wasn't making the directory. Here is what I did:
$uploaddir = '../../data/reports/uploads/' . $_POST['id'] . "/";
echo "NAME: " . $_FILES['files']['name'][0] . "\n";
foreach($_FILES['files']['name'] as $filenumber => $filename)
{
$uploadfile = $uploaddir . basename ($filename);
echo "UploadDir " . $uploaddir . "\n";
echo "UploadFile " . $uploadfile . "\n";
echo '<pre>';
echo "MKDir for UploadDir which is: ". $uploaddir . "\n";
mkdir ($uploaddir);
if (move_uploaded_file ($_FILES['files']['tmp_name'][$filenumber], $uploadfile))
{
echo "File is valid, and was successfully uploaded.\n";
}
else
{
echo "Possible file upload attack!\n";
}
echo 'Here is some more debugging info:';
print "</pre>";
}
var_dump ($_FILES);
I haven't gotten rid of some of the debug stuff yet, but that's the general solution.
Hello I have a view file and controller, what makes multiple inputs where I can upload files in to folder, but its uploading only one file in to folder. I know what is problem, but I dont know how to fix this or how to do this.
My Controller:
public function uploadFile() {
$filename = '';
if ($this->request->is('post')) { // checks for the post values
$uploadData = $this->data['files'];
//print_r($this->data['files']); die;
if ( $uploadData['size'] == 0 || $uploadData['error'] !== 0) { // checks for the errors and size of the uploaded file
echo "Failide maht kokku ei tohi olla üle 5MB";
return false;
}
$filename = basename($uploadData['name']); // gets the base name of the uploaded file
$uploadFolder = WWW_ROOT. 'files'; // path where the uploaded file has to be saved
$filename = $filename; // adding time stamp for the uploaded image for uniqueness
$uploadPath = $uploadFolder . DS . $filename;
if( !file_exists($uploadFolder) ){
mkdir($uploadFolder); // creates folder if not found
}
if (!move_uploaded_file($uploadData['tmp_name'], $uploadPath)) {
return false;
}
echo "Sa sisestasid faili(d): $filename";
}
}
My View file:
<?php
echo $this->Form->create('uploadFile', array( 'type' => 'file'));
?>
<div class="input_fields_wrap">
<label for="uploadFilefiles"></label>
<input type="file" name="data[files]" id="uploadFilefiles">
</div>
<button type="button" class="add_field_button">+</button> <br><br>
<form name="frm1" method="post" onsubmit="return greeting()">
<input type="submit" value="Submit">
</form>
<?php
echo $this->Html->script('addFile');
And this script what Im using in View :
$(document).ready(function() {
var max_fields = 3;
var wrapper = $(".input_fields_wrap");
var add_button = $(".add_field_button");
var x = 1;
$(add_button).click(function(e){
e.preventDefault();
if(x < max_fields){
x++;
$(wrapper).append("<div><input type='file' name='data[files]' id='uploadFilefiles'/><a href='#' class='remove_field'>Kustuta</a></div>");
}
});
$(wrapper).on("click",".remove_field", function(e){ //user click on remove text
e.preventDefault(); $(this).parent('div').remove(); x--;
})
});
I think that, the problem is in input names. If Im doing more inputs, then the inputs names are same, and thanks to this its uploading only one file in to webroot/files folder, but I want these all.
Can anybody help me or give me some tips.
Thanks !
Here is someone with almost exactly the same issue as you have:
Create multiple Upload File dynamically
Try doing the same. I haven't programmed PHP for quite some time, but I guess you should replace data[files] to just data[], so it creates a new array item for each field. Now you are giving each field the same name.
Then you can loop over them in your controller by using:
foreach($_FILES['data'] as $file){
//do stuff with $file
}
EDIT 2:
As you are saying, you want to upload the files (not to a db). So I guess this should work:
public function uploadFile() {
$filename = '';
if ($this->request->is('post')) { // checks for the post values
$uploadData = $this->data;
foreach($uploadData as $file){
if ( $file['size'] == 0 || $file['error'] !== 0) { // checks for the errors and size of the uploaded file
echo "Failide maht kokku ei tohi olla üle 5MB";
return false;
}
$filename = basename($file['name']); // gets the base name of the uploaded file
$uploadFolder = WWW_ROOT. 'files'; // path where the uploaded file has to be saved
$filename = $filename; // adding time stamp for the uploaded image for uniqueness
$uploadPath = $uploadFolder . DS . $filename;
if( !file_exists($uploadFolder) ){
mkdir($uploadFolder); // creates folder if not found
}
if (!move_uploaded_file($file['tmp_name'], $file)) {
return false;
}
echo "Sa sisestasid faili(d): $filename";
}
}
}
Try this function:
function multi_upload($file_id, $folder="", $types="") {
$all_types = explode(",",strtolower($types));
foreach($_FILES[$file_id]['tmp_name'] as $key => $tmp_name ){
if(!$_FILES[$file_id]['name'][$key]){
$return[$key]= array('','No file specified');
continue;
}
$file_title = $_FILES[$file_id]['name'][$key];
$ext_arr = pathinfo($file_title, PATHINFO_EXTENSION);
$ext = strtolower($ext_arr); //Get the last extension
//Not really uniqe - but for all practical reasons, it is
$uniqer = substr(md5(uniqid(rand(),1)),0,5);
$file_name = $uniqer . '_' . $file_title;//Get Unique Name
if($types!=''){
if(in_array($ext,$all_types));
else {
$result = "'".$_FILES[$file_id]['name'][$key]."' is not a valid file."; //Show error if any.
$return[$key]= array('',$result);
continue;
}
}
//Where the file must be uploaded to
if($folder) $folder .= '/';//Add a '/' at the end of the folder
$uploadfile = $folder . $file_name;
$result = '';
//Move the file from the stored location to the new location
if (!move_uploaded_file($_FILES[$file_id]['tmp_name'][$key], $uploadfile)) {
$result = "Cannot upload the file '".$_FILES[$file_id]['name'][$key]."'"; //Show error if any.
if(!file_exists($folder)) {
$result .= " : Folder don't exist.";
} elseif(!is_writable($folder)) {
$result .= " : Folder not writable.";
} elseif(!is_writable($uploadfile)) {
$result .= " : File not writable.";
}
$file_name = '';
}
else {
if(!$_FILES[$file_id]['size']) { //Check if the file is made
#unlink($uploadfile);//Delete the Empty file
$file_name = '';
$result = "Empty file found - please use a valid file."; //Show the error message
}
else {
#chmod($uploadfile,0777);//Make it universally writable.
}
}
$return[$key]=array($file_name,$result);
}
return $return;
}
html: <input type="file" name="data_file[]" id="uploadFilefiles">
Call by multi_upload("data_file","upload_to_folder","pdf,jpg,txt,bmp")
I have a following function that downloads the file whose name is passed as a parameter in the url. Here is the code:
public function actionDownloadFile($filename)
{
$file = Yii::app()->request->getBaseUrl(true) . '/upload/digitaluploads/' . $filename;
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="' . basename($file) . '"');
readfile($file);
}
This function is called from view file when the user clicks on download button from the view:
<a class="digital-download" href="<?php echo Yii::app()->request->getBaseUrl('true'); ?>/site/downloadfile/filename/<?php echo urlencode($digital_download['filename']); ?>">Click here to download</a>
This works for filename that don't have spaces like it will work for file with the name like somefile.mp3 but it does not work for the files that have spaces in that. i.e it fails for the files whose name contains spaces like 'maid with the flaxen hair.mp3'.
As you can see I have even encoded the parameter in the url using urlencode. I tried using decode in action as well but all I get is the broken page.
Anyone?
use this function to avoid space and other possible problems:
function fullescape($in)
{
$out = '';
for ($i=0;$i<strlen($in);$i++)
{
$hex = dechex(ord($in[$i]));
if ($hex=='')
$out = $out.urlencode($in[$i]);
else
$out = $out .'%'.((strlen($hex)==1) ? ('0'.strtoupper($hex)):(strtoupper($hex)));
}
$out = str_replace('+','%20',$out);
$out = str_replace('_','%5F',$out);
$out = str_replace('.','%2E',$out);
$out = str_replace('-','%2D',$out);
return $out;
}
found here: http://php.net/manual/en/function.urlencode.php
try this :
str_replace(' ', '%20', 'your url here');
