PHP - How To Restrict File Sizes And File Type And Prevent Overwriting In Upload.php

So, I'm learning how to upload pictures into a system from my awesome PHP book. I've looked and looked through the script but I can't figure out whats wrong with it.

Goal:
The script is meant to save a full version of the image in the images folder and a thumbnail in the thumbnail folder.
Bug:
The full image does not appear in any folder, and the thumbnail is created but its put in the images folder.

I've checked the GD library, and everything is supported.

['drama_image'] is the name of the file

I wanna echo it out in the box of file upload so when I save , the default picture will still be there instead of being overwritten as the box does not have any value in it.

Hello, all: been trying to convert this little single-file upload to multiple by naming each file form-field as "userfile[]" as it's supposed to automatically treat them as an array.. but no luck!  Can you guide me as to what am I doing wrong??
appreciate the help!


Code: [Select]
<?php

if (!isset($_REQUEST["seenform"])) {
?>
   <form enctype="multipart/form-data" action="#" method="post">
   Upload file: <input name="userfile[]" type="file" id="userfile[]">
   Upload file: <input name="userfile[]" type="file" id="userfile[]">
   <input type="submit" value="Upload">
   <input type="hidden" name="seenform">
   </form>
<?php
} 
else 
{ // upload begins
$userfiles = array($_FILES['userfile']);
foreach ($userfiles as $userfile)
{ // foreach begins
   $uploaded_dir = "uploads/";
   $userfile = $_FILES['userfile']["name"];
   $path = $uploaded_dir . $userfile;
   if (move_uploaded_file($_FILES['userfile']["tmp_name"], $path)) 
     {
   print "$userfile file moved";
   // do something with the file here
    } else 
{
   print "Move failed";
}
} // foreach ends
} // upload ends

?>

I have solved this now.

HI All,

I have a form submission that uploads a photo as well as submitting other data.

I would like to change the name of the photo to the id of the person record (created automatically on by the database) then a hyphen, then their first name and lastname. (i am flexible on this).

This file name will also need to be submitted into the person record so the photo and the person can be linked.

I am struggling with this one - but here is the code i have so far.

 

<?php 
include 'includes/dbconn.php';

$target_dir = "img/people/";
$target_file = $target_dir . basename($_FILES["personHeadshot"]["name"]);
$uploadOk = 1;
$imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));

if ($_SERVER['REQUEST_METHOD']=='POST'){

	$fn = $_POST['fname'];
	$ln = $_POST['lname'];
	$ad1 = $_POST['ad1'];
	$ad2 = $_POST['ad2'];
	$city = $_POST['city'];
	$post = $_POST['postcode'];
	$tel = $_POST['phone'];
	$email = $_POST['email'];
	$crole = $_POST['comRole'];
	$OFA = $_POST['OFA'];
	$playerType = $_POST['playerType'];
	$team = $_POST['primaryTeam'];


	$stmt = $conn->prepare("
	                       INSERT IGNORE INTO person (fname, lname, committee_role_id, player_type_id, team_id, ad1, ad2, city, postcode, mobile, email, on_field_auth_id) 
	                       VALUES (?,?,?,?,?,?,?,?,?,?,?,?)
	                       ");
	$stmt -> bind_param(ssiiissssssi, $fn, $ln, $crole, $playerType, $team, $ad1, $ad2, $city, $post, $tel, $email, $OFA);
	$stmt -> execute();

	// Check if image file is a actual image or fake image
//photo upload
	$check = getimagesize($_FILES["personHeadshot"]["tmp_name"]);
  if($check !== false) {
    echo "File is an image - " . $check["mime"] . ".";
    $uploadOk = 1;
  } else {
    echo "File is not an image.";
    $uploadOk = 0;
  }
//photo upload

	header("location: ../admin-people-list.php");
}
// Check if file already exists
if (file_exists($target_file)) {
  echo "Sorry, file already exists.";
  $uploadOk = 0;
}

// Check file size
if ($_FILES["personHeadshot"]["size"] > 500000) {
  echo "Sorry, your file is too large.";
  $uploadOk = 0;
}

if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
&& $imageFileType != "gif" ) {
  echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
  $uploadOk = 0;
}

// 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["personHeadshot"]["tmp_name"], $target_file)) {
    echo "The file ". basename( $_FILES["personHeadshot"]["name"]). " has been uploaded.";
  } else {
    echo "Sorry, there was an error uploading your file.";
  }
}

 

Hello! I have this validation script that seems to work great until I add the size validation. I'm ready to pull my hair out! Can someone tell me what I'm doing wrong?

Code: [Select]
if (isset($_POST['Submit'])) {
$user_id = $userdata[user_id];
    $number_of_file_fields = 0;
    $number_of_uploaded_files = 0;
    $number_of_moved_files = 0;
    $uploaded_files = array();
$max_filesize = 5242880; // Maximum filesize in BYTES (currently 5MB).
    $upload_directory = dirname(__file__) . '/'.$user_id.'/'; //set upload directory
if (!is_dir($upload_directory)) {
    mkdir($upload_directory, 0777, true);
}

    for ($i = 0; $i < count($_FILES['images']['name']); $i++) {
        $number_of_file_fields++;
        if ($_FILES['images']['name'][$i] != '') { //check if file field empty or not
            $number_of_uploaded_files++;
if($_FILES['images']['size'] > $max_filesize){
echo "<b class='red'>Max file size is 5MB.</b><br/>";
$sz = true;
}
$ext = validate_extension($_FILES['images']['name'][$i]);
if (($ext == true) && ($sz == true)){
$uploaded_files[] = $_FILES['images']['name'][$i];
if (move_uploaded_file($_FILES['images']['tmp_name'][$i], $upload_directory . $_FILES['images']['name'][$i])) {
$number_of_moved_files++;
            }
}else { echo "<b class='red'>File extention error. Only .doc, .pdf, .jpg and .gif files are allowed. </b><br/>";
}

        }

    }
if ($number_of_uploaded_files >= 1){
echo "Number of files submitted:<b class='red>".$number_of_uploaded_files."</b><br/>";
echo "Number of successfully uploaded files:<b class='red>".$number_of_moved_files."</b><br/><br/>";
echo "Uploaded File Name(s):<br/>" . implode('<br/>', $uploaded_files);
}


}
As of now it results in every uploaded file returning the error "Max file size is 5MB."

I have a script that I am trying to transfer one file from a remote server to my local server and save it. The files can be quite large. I have successfully backed up around 200 MB... But, anything over that seems to fail with a strange error... I was hoping for a little guidance... here is my code and error/warning that I get:

PHP Code:
function remote_capture($tmp_url, $filename)
   {
   
      $r_handle = fopen($tmp_url, "rb");
      $d_handle = fopen($filename, 'w');
      
      if($r_handle&&$d_handle)
      {
          while(($buffer = fgets($r_handle)) !== false)
          {
            fputs($d_handle, $buffer);
          }
         
          fclose($r_handle);
         fclose($d_handle);
         
         return true;
         
      }
      else
      {
         return false;
      }
   
   }

Hey all

So have been working on a file upload script, it was uploading the file but also adding the path name instead of NULL to mysql when no image was to upload, that is now fixed however now it won't upload the actual image to the directory.  I tried undoing the mysql changes but it still won't upload the image to the directory.  Am testing on my own computer using xampp so no file permission issues, plus it was working before.  Any help much appreciated.

Thanks

How do I Upload Multiple Files using a PHP form and script? 10 files at one time would be great.
Ultimately I need a photo upload and management script.

Here is my current single file upload form:

<form action="upload.php" method="post"
enctype="multipart/form-data">
<label for="file">Upload a Photo:</label>
<input type="file" name="file" id="file" />
<br />
<input type="submit" name="submit" value="Submit" />
</form>

</body>
</html>


Here is the Php Script:

<?php
if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/pjpeg"))
&& ($_FILES["file"]["size"] < 200000))
  {
  if ($_FILES["file"]["error"] > 0)
    {
    echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
    }
  else
    {
    echo "Upload: " . $_FILES["file"]["name"] . "<br />";
    echo "Type: " . $_FILES["file"]["type"] . "<br />";
    echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
    echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br />";

    if (file_exists("upload/" . $_FILES["file"]["name"]))
      {
      echo $_FILES["file"]["name"] . " already exists. ";
      }
    else
      {
      move_uploaded_file($_FILES["file"]["tmp_name"],
      "uploads/" . $_FILES["file"]["name"]);
      echo "Stored in: " . "uploads/" . $_FILES["file"]["name"];
      }
    }
  }
else
  {
  echo "Invalid file";
  }
?>

Been looking on the web on and off for the past few days but can't seem to find a list of all file types that PHP (or is it Apache) appreciates.

Like when you go and upload file using a form and then it outputs:

Quote

Array
(
    [upload_file] => Array
        (
            [name] => discount_xcart_orders.csv
            [type] => text/comma-separated-values
            [tmp_name] => /tmp/phprAk2R6
            [error] => 0
            [size] => 674
        )

)



Is there an entire list of file types that this '[type] => text/comma-separated-values' falls under?

Just out of interest of course,
Jeremy.

I have two scripts: script1.php and script2.php.   Script1 creates if it doesn't already exist and adds to a session named "SESSION1" and displays it:   Script2 similarly adds to a session named "SESSION2", but then needs to display the session used by the first script (i.e. SESSION1), and then goes back to its original session (SESSION2).   Script1 works perfect.  But when Script2 is executed, it changes the session ID in the SESSION1 cookie to the same value as used in its SESSION2 cookie.  If Script1 is later executed, it obviously lost its previous session values as it is now using a new session ID.   If I comment out the two session_name() lines, it will not overwrite the other session, however, this doesn't provide the functionality I need.   What is causing this and how do I prevent it????   script1.php

<?php
// script 1.  Will be accessed as http://one.example.com

$t=time();

//Access the primary session for script 1
session_name('SESSION1');
session_start();
$_SESSION['s1_'.$t]=$t;
echo("SESSION1<pre>".print_r($_SESSION,1)."</pre>");
?>

script2.php

<?php
// script 2.  Will be accessed as http://two.one.example.com

$t=time();

//Access the primary session for script 2
$default_name=session_name('SESSION2');
session_start();
$_SESSION['s2_'.(2*$t)]=2*$t;
echo("SESSION2<pre>".print_r($_SESSION,1)."</pre>");

//Use session created by script 1
$old_id_script2 = session_id();
session_write_close();
$old_name_script2 = session_name('SESSION1');
session_start();
echo("SESSION1<pre>".print_r($_SESSION,1)."</pre>");

//Go back to primary session
session_write_close();
$old_id_script1 = session_id($old_id_script2);
$old_name_script1 = session_name($old_name_script2);
session_start();
echo("SESSION2<pre>".print_r($_SESSION,1)."</pre>");

echo("default_name: $default_name<br>");
echo("old_id_script2: $old_id_script2<br>");
echo("old_name_script2: $old_name_script2<br>");
echo("old_id_script1: $old_id_script1<br>");
echo("old_name_script1: $old_name_script1<br>");
?>

How would i do a random file name for my upload script

Code: [Select]
$type = $_FILES['uploadedfile']['type'];
// Where the file is going to be placed
$target_path ="/***/***/public_html/****/lofslidernews/images/";

/* Add the original filename to our target path. 
Result is "/images/uploads/filename.extension" */
$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);

$uploadedfile2 = $_FILES['uploadedfile']['name'];

if (empty($quicktitle) || empty($maintitle ) || empty($description ) || empty($uploadedfile))
   {
       $_SESSION["promoerror"] = "Please Select an image and enter a Quick Title, Main Title and Description!" ;
       header("Location: promo.php"); //This sets the redirection information
       //echo "Going to login.php, username or password is empty";
       exit(); //Ends the script and redirects to above
   }


$query = "INSERT INTO promotion (title, maintitle, description, image) VALUES ('$quicktitle','$maintitle','$description', '$uploadedfile2')";



$result = mysql_query($query) or die ("Error in query: $query. ".mysql_error());


if ( ( $type != "image/jpeg") && ($type != "image/gif") )

{
die ("That format is not allowed");
}
else
{
    move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path);
header("Location: promo.php");
$_SESSION["promoerror"] = "Added Successfully!";

}

A shipping vendor (like Stamps.Com) provides me a Printable Shipping Label to display on my website for Visitors to print.

When Visitors come to my page, my PHP code:
1.) connects to Shipping Vendor via an API,
2.) downloads and converts the base64 data to image
3.) names the image to Customer Order Number.png
4.) saves image in directory
5.) then displays image to Visitor.

$Shipping_Label_Data = $LabelVendor->data[0]->contents; // vendor's API
file_put_contents('Label-Directory/'.$Order_Number.'.png',base64_decode($Shipping_Label_Data));

echo '<img src="/Label-Directory/'.$Order_Number.'.png" />';

Later I realized the security flaw: any snooper can fish for other Visitor's labels in my Label directory.

What is the best way to prevent the display of other people's labels?

Thank you!!

I use jQuery when adding messages. However, the file can be called directly. For example: includes/add_comment.php?id=2

So, I can make a form and call this file directly to add a message. ID is user id and form can be submited with HTML form wherever are located.

How to prevent direct access to the file when called through a Ajax?

Hi.

I want to create a list of files in a directory. But I don't want all the files to be listed, only .gif, .jpg and .bmp.

Does anyone know the PHP code how to do that? (My directory name is 'images' if you need that).

Thanks!
