PHP - $_files['userfile']['tmp_name']

Hi,

My $_FILES is not working.
Its working when Im doing my project on the local host.
After I uploaded my project to the server, the $_FILES is not working.

Im trying to upload images.
the $_FILES['name'] couldn't read anything. its like no file there.

whats causes it? any other way to read from <input type='file'/> ? or way to solve this?

Thank You.

I need to check whether the user has uploaded a file when submitting a form using isset. If they have, the file path is recorded to the database. If they haven't nothing needs to occur, the file path field will just be NULL.
Here is my issue:
When I test it with uploading no file I'm still getting "images/" from my $ filelocation variable recorded to the database.
How can I fix this?

<?php 

    if(isset($_FILES['userfile'])) 
    { 
    $fileupload = $_FILES['userfile']['name']; 
    $filetype = $_FILES['userfile']['type']; 
    $filesize = $_FILES['userfile']['size']; 
    $tempname = $_FILES['userfile']['tmp_name']; 
    $filelocation = "images/$fileupload"; 
    } 
    else 
    { 
    $filelocation = NULL; 
    } 


        if (!move_uploaded_file($tempname,$filelocation)) { 
                switch ($_FILES['userfile']['error']) 
                { 
                 
                    case UPLOAD_ERR_INI_SIZE: 
                        echo "<p>Error: File exceeds the maximum size limit set by the server</p>" ;

I'm using a upload class that works with $_FILES, but have a couple of reasons to need the content of php://input:

1) When submitting PDF forms as a complete form, the form is available in php://input.

2) An ajax uploader I'd like to use submits the file making it only available in php://input.

I know I could use an if statement to check $_FILES else php://input, but I'm concerned about security, and being able to identify the filetype, get the size, etc. I'm skipping over some other details, because I need to leave in 5 minutes.

I've not seen any classes that merge the two ( $_FILES and php://input ), and really haven't seen any that are specifically for php://input. Can anyone offer advice or point me in the right direction?

When you try and upload files using a size limiting feature, when you consider $_FILES['form_element']['size'] what actually is this measured in again?

I seem to have forgotten what it's actually measured in, if I was to say a limit on $_FILES['myform_file_upload']['size'] < 20000, what does the 20000 actually mean?

Any help is appreciated,
Jeremy.

Hi,
I have simple php code with HTML.. but its not working with all browser, some time its works in Chrome sometimes its not working in IE
I have saved this filr as index.php

its code is:

<html>
<head> <title>
Upload
</title> </head>
<body>
<form action="index2.php" method="POST" enctype="multipart/form-data">
Image:
<input type="file" name="myImage" />
<input type="submit" value="Upload" />
</form>
<?php

echo $_FILES["myImage"]["tmp_name"];

?>
</body>
</html>

For uploading files, I use a class which accepts an uploaded file array, validates that it has a name, tmp_name, type, error, and size key, validates that it doesn't have errors and meets various requirements, and moves it to the applicable folder.

For another applicable, I will be generating the file directly on the server, however, wish to use this same class.  Will I need to manually create this "file" array, or is there a native PHP function to accept a path and automatically do it?

Thanks

Ok, I have this working on another page from a long time ago, but it's not working right he It gets past the if($num == 0) part, but when it's seeing if the files has been uploaded, it's not getting past that and it won't give me my error message too. So I have a feeling it's getting past it, but it's not uploading it into the software/ directory and not inserting it into the database.
I get no errors in my error_log or my default errors I have set up under the variable, $message.

Code: [Select]
$target_path = "software/";
$basename = strtolower(basename($_FILES['softwarePath']['name']));

$target_path = $target_path . $basename;
$sql = "SELECT softwarePath FROM software WHERE softwarePath='$target_path'";
$result = mysqli_query($cxn, $sql) or die(mysqli_error());
$num = mysqli_num_rows($result);
if($num == 0)
{
if(move_uploaded_file($_FILES['softwarePath']['tmp_name'], $target_path))
{
$sql = "INSERT INTO software(softwareName,softwareType,softwareDesc,softwarePath,ITOnly) VALUES('$softwareName','$softwareType','$softwareDesc','$target_path','$ITOnly')";
mysqli_query($cxn,$sql) or die(mysqli_error());
header("Location: search_software.php");
}
}
else
{
$message = "There is already a file with that name.";
}

I have a multipart forum that can load a photo if needed.

My problem is that if no photo is selected for upload it deletes any data in the database for the current row if there is a photo.

What I'm trying todo is not load upload_thumb.inc.php if no photo is selected and not run the UPDATE query

 // If everything's Okay Process the whole form

if (empty($errors)) { 

//Run some of the script here

if (isset($_FILES['image'])) { // Upload thumb if one is selected
include_once ('../includes/upload_thumb.inc.php');

// run UPDATE query script to insert photo location and stuff in db

}

// run more script here

}


What's happening if I have a photo and don't upload another photo the guery over writes the db info for the current photo.

The idea with isset($_FILES['image']) was to not load upload_thumb.inc.php and not to run the UPDATE script

Thanks

I have an index.php file which includes my form and code to move the user's uploaded file to s3. My HTML form calls a js function sendEmails() which makes an AJAX request to another php script dbSystem() to validate the emails input and add it to a database. Everything is working except that the php code in my index.php file (at the very bottom) does not execute. It's supposed to execute when the user uploads a file and presses submit but it doesn't go into the if statement. I tried putting the $fileName = basename($_FILES["fileName"]["name"]) statement before the if statement but I get an undefined index error. I put my a comment in my code to show which if statement I am talking about.

This is my HTML code in index.php:

<form action="javascript:void(0)" method="POST" id="files" enctype="multipart/form-data">
    <label class="col-md-4 col-form-label text-md-right">Select File:  <span class="text-danger">*</span></label>
    <input type="file" id="userFile" name="fileName" style="cursor: pointer; max-width: 170px;" onchange="enableBtn()">

    <label class="col-md-4 col-form-label text-md-right">Authorized Users:  <span class="text-danger">*</span></label>
    <input placeholder="Enter e-mail(s) here..." id="req" autocomplete="off"/>

    <button id="submitBtn" name="submitBtn" class="<?php echo SUBMIT_BUTTON_STYLE; ?>" onclick="return sendEmails()" disabled>Submit</button>
</form>

This is my php code in index.php:

<?php
$conn = new mysqli($servername, $username, $password, $db);
$sql = "SELECT sender_id, sender_email, receiver_emails, receiver_ids, file_name from filedrop_logs";
$result = mysqli_query($conn, $sql);

if ($result) {
    echo "<div class='outputDiv'>";
    echo "<table id='sharedOthers'>";
    echo "<thead><tr class='headings'>";
    echo "<th class='files'>Files</th>";
    echo "<th class='users'>Users</th>";
    echo "</tr></thead>";

    while ($row = mysqli_fetch_assoc($result)) {
        $receiverEmails = $row['receiver_emails'];
        $fileName = $row['file_name'];

        echo "<tbody id='bodyOthers'>";
        echo "<tr id='rowOthers'>";
        echo "<td>$fileName<br>";

        $objects = getListofObjects('FileDrop');
        foreach ($objects as $object) {
            $file = $object['Key'];
            $splits = explode('/', $file);
            if (end($splits) !== '') {
                $presignedUrl = getPresignedUrlForPrivateFile($object['Key'], '+20 minutes');
                $link = '<a href="'.$presignedUrl.'">Download</a>';
                echo $link;
            }
        }

        echo "&nbsp;&nbsp;&nbsp;&nbsp;<a href=''>Delete</a></td>";
        echo "<td>$receiverEmails</td>";
        echo "</tr></tbody>";
    }
    echo "</table></div>";
}
?>
<?php
//the if statement below doesn't execute

if(isset($_SERVER['REQUEST_METHOD']) && $_SERVER['REQUEST_METHOD'] === 'POST' && isset($_FILES["fileName"])) {
$fileName = basename($_FILES["fileName"]["name"]);
$error = $_FILES["fileName"]["error"];
$tmpName = $_FILES["fileName"]["tmp_name"];

if (isset(fileName) && $fileName != '' && $tmpName != '' && sys_get_temp_dir()) {
    $separator = DIRECTORY_SEPARATOR;
    $newDir = sys_get_temp_dir() . $separator . "FileDrop" . microtime(true);

    if (!file_exists($newDir)) {
        mkdir($newDir, 0777, true); // creates temp FileDrop directory
        $tempFilePath = $newDir . $separator . $fileName; // creates temp file inside FileDrop directory

        if (move_uploaded_file($tmpName, $tempFilePath)) { // moves file to tmp folder
            $s3FileName = "FileDrop" . substr($newDir, 4) . $separator . $fileName;
            $result = putFileToS3($s3FileName, $tempFilePath, 'public-read');
            deleteDir($newDir);
        }
    }
}
}
?>

This is my js code in case you want to see it:

function sendEmails() {
var fileData = $('#userFile').prop('files')[0];
var formData = new FormData();
formData.append('tags', JSON.stringify(tags));
formData.append('fileName', fileData);
$.ajax({
    type: "POST",
    url: "../FileDrop/dbSystem.php",
    processData: false,
    contentType: false,
    data: formData,
    success: function(result) {
        result = JSON.parse(result);
        if (result.validity === "valid emails") {
            location.reload();
            resetInputs(); //IMPORTANT
            $(".outputDiv").show();
        }
        else {
            var tagsBrackets = result.emails.toString().replace(/[\[\]']+/g,'');
            var tagsQuotes = tagsBrackets.replace(/['"]+/g, '');
            var tagsInvalid = tagsQuotes.replace(/,/g, ", ");
            $('#alertModal').modal({show:true});
            document.getElementById('invalid').textContent = tagsInvalid;
        }
    }
});
return false;
}

I've been stuck on this for so long, so I'd really appreciate the help!!

Hi Everyone,
I have a rather stupid question, but I haven't been able to find the correct method / syntax to do this. I want to allow users to upload a maximum of 5 photos - less then 5 is OK too. I've been testing the following script and haven't gotten it to ignore error # 4 (no file uploaded):

Code: [Select]
   if ($_FILES['userfile']['error'] == 1 || 2 || 3 || 6 || 7)   {
 
    echo 'Problem: ';
    switch ($_FILES['userfile']['error'])   {

      case 1: echo 'File exceeded upload_max_filesize';
  break;
      case 2: echo 'File exceeded max_file_size';
  break;
      case 3: echo 'File only partially uploaded';
  break;
  case 6:   echo 'Cannot upload file: No temp directory specified.';
  break;
  case 7:   echo 'Upload failed: Cannot write to disk.';
  break;
    }
    exit;
  }
I will be using a while loop and incrementing through the script (this is simpler version). Does anyone know the proper syntax for the IF statement ' if ($_FILES['userfile']['error'] == 1 || 2 || 3 || 6 || 7)" ?
Thanks much,
Rick

How do i display the image uploaded after the form has been submitted? After the form is submitted it will be a preview page, so i'm not storing the image type BLOB in MySQL yet. How do i display $_FILES['image']?

Code: [Select]
<?php

if(isset($_POST['submit'])) {

 //preview page

$info = getimagesize($_FILES['image']['tmp_name']);
$imagetype = $info['mime'];
$tmpname = $_FILES['image']['tmp_name'];
$fp = fopen($tmpname,'r');
$data = fread($fp,filesize($tmpname));
$data = addslashes($data);
fclose($fp);

} else {
?>

<form enctype="multipart/form-data" action="http://www.example.com/submit" method="POST">
<input type="file" name="image" value="" size="50" />
<input type="submit" name="submit" value="submit" />
</form>

<?php
}

?>
