Hi I'm fairly new to HTML, PHP, MySQL etc.. I am wondering if there is a predefined upload limit using $_FILES. I ask because when I try to upload 8 images of around 1.5 megabytes the code does not work but when I upload 10 images of around 60 kilobytes the code works fine.
Here is my code and feel free to make any criticisms/comments about it:
</head>
<body>
<form action="test.php" method="POST" enctype="multipart/form-data" >
<input type="file" name="image[]" multiple="multiple">
<input type="submit" value="upload">
</form>
<?php
include 'connect.php';
if(!empty($_FILES['image']['tmp_name'])){
$allowed = array('jpg', 'gif', 'png', 'jpeg');
$count = 0;
foreach($_FILES['image']['name'] as $key => $name){
$image_name = $name;
$tmp = explode('.', $image_name);
$image_extn = strtolower(end($tmp)); //can only reference file
$image_temp = $_FILES['image']['tmp_name'][$count];
$count = $count +1;
if(in_array($image_extn, $allowed) === true){
$image_path = 'images/' . md5($image_name) . '.' . $image_extn;
move_uploaded_file($image_temp, $image_path);
mysql_query("INSERT INTO store VALUES ('', '$image_name', '$image_path')") or die(mysql_error());
$lastid = mysql_insert_id();
$image_link = mysql_query("SELECT * FROM store WHERE id = $lastid");
$image_link = mysql_fetch_assoc($image_link);
$image_link = $image_link['image'];
$uploaded[] = $image_link;
}
else{
echo 'Incorrect file type. Allowed: ';
echo implode(', ', $allowed);
}
}
}
if(!empty($uploaded)){
foreach($uploaded as $new){
echo "<a href = $new>$new</a><p></p>";
}
}
else{
echo "Please select an image.";
}
?>
</body>
</html>
You are trying to upload an array of files, you will not be able to upload more than 20 files due to max_file_uploads limit in php.ini which is by default set to 20.
So you have to increase this limit to upload more than 20 files.
Note: max_file_uploads can NOT be changed outside php.ini. See PHP "Bug" #50684
Here are the settings you want to change in php.ini:
post_max_size
This setting controls the size of an HTTP post, and it needs to be set larger than the upload_max_filesize setting.
upload_max_filesize
This value sets the maximum size of an upload file.
Remember to restart your web server after making these changes.
Ref:
http://www.php.net/manual/en/ini.core.php#ini.post-max-size
http://www.php.net/manual/en/ini.core.php#ini.upload-max-filesize
A few settings in your php.ini could be causing this. Look into memory_limit, post_max_size, upload_max_filesize. You could also be timing out. The best way to find out specifically is error_reporting(E_ALL);ini_set('display_errors','1');
In php.ini, there will be a post_max_size and upload_max_filesize directive.
You should also define a MAX_FILE_SIZE hidden input within your form, as per
http://www.php.net/manual/en/features.file-upload.post-method.php

I'm a PHP newbie and have written a script to process form uploads. It works for small files(less than 1Mb). However when I try to upload an ~4Mb pdf file it returns an error message. What am I doing wrong?
PS: I ran php_info, got the value of "upload_tmp_dir" and set it to a directory owned by the apache process(www-data)
My client-side code is
<form action="upper.php" method="post" enctype="multipart/form-data">
<input type="file" name="myFile"><br>
<input type="submit" value="Upload">
</form>
Upper.php contains
define("UPLOAD_DIR", "/var/www/html/upload/");
if (!empty($_FILES["myFile"])) {
$myFile = $_FILES["myFile"];
if ($myFile["error"] !== UPLOAD_ERR_OK) {
echo "Error is " . $myFile["error"];
//echo "<p>An error occurred.</p>";
exit;
}
$name = preg_replace("/[^A-Z0-9._-]/i", "_", $myFile["name"]);
// don't overwrite an existing file
$i = 0;
$parts = pathinfo($name);
while (file_exists(UPLOAD_DIR . $name)) {
$i++;
$name = $parts["filename"] . "-" . $i . "." . $parts["extension"];
}
// preserve file from temporary directory
$success = move_uploaded_file($myFile["tmp_name"], UPLOAD_DIR . $name);
if (!$success) {
echo "<p>Unable to save file.</p>";
exit;
}
// set proper permissions on the new file
chmod(UPLOAD_DIR . $name, 0644);
}
Most probably you have wrong config in you php.ini file.
You need to set
; Maximum allowed size for uploaded files.
upload_max_filesize = 40M
; Must be greater than or equal to upload_max_filesize
post_max_size = 40M
its already described here: PHP change the maximum upload file size
You ned to set values in php.in file.
Open the file,
Find upload_max_filesize and post_max_size lines.
Change this two value. (M= MB)
; Maximum allowed size for uploaded files.
upload_max_filesize = 20M
; Must be greater than or equal to upload_max_filesize
post_max_size = 20M
Restart the sever for effect.
Note:
You can set any number. But not use any decimal value.
Open the php.ini file in NOTEPAD. Don't user wordpad or any word processor.
I want to upload the files in html as follow :
<tr><td><?php _e("Upload Trust Logo","emarksheet"); ?></td><td><label class="btn btn-danger" for="file-sel"><input id="file-sel" type="file" name="imaget" style="display:none;" size="25" />Browse to Upload Logo ....</label></td></tr>
<tr><td><?php _e("Upload Institute Logo","emarksheet"); ?></td><td><label class="btn btn-primary" for="file-sel2"><input id="file-sel2" type="file" name="image" style="display:none;" size="25" />Browse to Upload Logo ....</label></td></tr>
Two upload these files. My php code is as follow :
$path = plugin_dir_path(__FILE__);
$file = $_FILES['image'];
//print_r($_FILES);
$name1 = $file['name'];
$type = $file['type'];
$size = $file['size'];
$tmppath = $file['tmp_name'];
move_uploaded_file ($tmppath, $path.'logos/'.$name1);
//upload data end
//upload trust logo`
$file2 = $_FILES['imaget'];
//print_r($_FILES);
$name2 = $file2['name'];
$type2 = $file2['type'];
$size2 = $file2['size'];
$tmppath2 = $file2['tmp_name'];
move_uploaded_file ($tmppath2, $path.'logos/'.$name2);
When I upload the files. The file name with $name2 is uploaded but the file with name $name1 is not uploaded
Please help why it not be uploaded
As you posted, the 'image' image has an error 4 code. That means no file was uploaded, as seen here:
http://www.php.net/manual/en/features.file-upload.errors.php
Why?
Since you are getting info in $_FILES, then you are not posting a total amount of data larger than the post_max_size php.ini directive, as, in this case, $_FILE would be completelly empty.
Then, maybe the php.ini upload_max_filesize, the maximum size for a singe file, is exceeded or the max_file_uploads is set to one, as max_file_uploads is the maximum number of files allowed to be uploaded simultaneously.
Check those params at http://php.net/manual/en/ini.core.php and in your php.ini file.
I tried this snippet in my localhost server, and placed in [www_root]/tests/uploads/test1.php (note I just used the relevant part for our case):
<?php
if (empty($_FILES)) {
echo "<form enctype='multipart/form-data' method='POST' action='http://localhost/tests/uploads/test1.php'>";
echo '<input id="file-sel" type="file" name="imaget" size="25" />';
echo '<input id="file-sel2" type="file" name="image" size="25" />';
echo '<button type="submit">Submit</button>';
} else {
echo print_r($_FILES);
}
And both files where correctly uploaded. Then the problem must be in the PHP configuration, not in the actual PHP code.
My values in php.ini:
post_max_size=8M
upload_max_filesize=2M
max_file_uploads=20
This means I can upload 20 files at the same time, but they can not exceed 8M in total nor an individual file can exceed 2M.
EDIT: after modifying the php.ini file, the server must be restarted in order to get those new values loaded.
Hope it helps.
I want to upload files from my server. I had written this piece of code months ago when it worked fine, but now I have no idea what's going wrong.
I basically want to move the file to a folder "uploads" in my server and then store the path in the database.
The uploaded file doesn't get reflected in the database.
if(isset($_POST['submit']))
{
require("dbconn.php");
$filename = $_POST['filename'];
$name = $filename . "." . pathinfo($_FILES['ufile']['name'],PATHINFO_EXTENSION);
//$name = $_FILES['ufile']['name'];
//$size = $_FILES['file']['size']
//$type = $_FILES['file']['type']
$tmp_name = $_FILES['ufile']['name']; //was tmp_name
$error = $_FILES['ufile']['error'];
if(isset($name))
{
if(!empty($name))
{
$location = 'uploads/';
if(move_uploaded_file($tmp_name, $location.$name))
{
echo "hi";
$filename = $_POST['filename'];
$filepath = $location.$name;
$advname = $_POST['advname'];
$year = $_POST['year'];
$cname = $_POST['cname'];
$ctype = $_POST['ctype'];
$sqlq = "INSERT INTO file(filename, filepath, advname, year, cname, ctype) VALUES ('".$filename."','".$filepath."','".$advname."','".$year."','".$cname."','".$ctype."');";
$result = mysql_query($sqlq);
if(!$result)
{
die("Error in connecting to database!");
}
}
}
}
}
There seems to be a problem in the
if(move_uploaded_file($tmp_name, $location.$name))
statement. This condition is evaluated as false.
If $_FILES['ufile']['error'] gives you a value of 1 then the upload_max_filesize in your config is set to a smaller value that the file you are trying to upload.
You cannot change the upload_max_filesize from within your code.
If you have access to your php.ini, .htaccess, httpd.conf or .user.ini you can change this value in any of those files.
So you would need to add or modify the parameter from its default of 2M (2meg)
upload_max_filesize = 20M
Its also a good idea to check the post_max_size at the same time as this may also have an effect on the max size of the file uploaded, make sure post_max_size is larger than upload_max_filesize as this should allow extra space for the other fields that you will be uploading as part of the post
I'm using this code to upload folder files.
<form action="file_transfer.php" method="post" enctype="multipart/form-data" name="form1">
<input type="file" name="file_input[]" id="file_input" multiple="" webkitdirectory="">
<input type='submit' class='btn' id='btn_upload_file' value='UPLOAD' data-loading-text='loading....'/>
</form>
And file_transfer.php
$uploads_dir = 'C:/xampp/htdocs/awoc_inspection/Images/IMAGES/';
for($i = 0; $i < sizeof($_FILES['file_input']['name']); $i++){
$tmp_name = $_FILES['file_input']['tmp_name'][$i];
$name = $_FILES['file_input']['name'][$i];
echo $_FILES['file_input']['tmp_name'][$i];
echo $_FILES['file_input']['name'][$i];
echo"<br/>";
move_uploaded_file($tmp_name, "$uploads_dir/$name");
}
It does not show any error but when I go to C:/xampp/htdocs/awoc_inspection/Images/IMAGES/
folder there is no image. I don't know why this code can't move uploaded folder files please help me :(
It doesnt print error cause you didnt ask it to do:
echo $_FILES["file"]["error"][$i];
The problem might be that your directory doesnt have good permission try chmod 775 or 777
Also do:
echo $result = move_uploaded_file($tmp_name, "$uploads_dir/$name");
to check whether $result is true or false, if false then moving file wasnt done
Try to change the for condition with:
for($i = 0; $i < sizeof($_FILES['file_input']); $i++) {

I've overcome own my problem :) .. thank's everyone for your answers ... the only problem why I can't upload pictures it is because the picture that I'm trying to upload is 3mb above and the maximum upload file_size in php is 2mb .
I've changed php.ini to
;;;;;;;;;;;;;;;;
; File Uploads ;
;;;;;;;;;;;;;;;;
; Maximum allowed size for uploaded files.
; http://php.net/upload-max-filesize
upload_max_filesize = 50M
$image = $_FILES['picture']['name'];
$id=$_SESSION['id'];
//This function separates the extension from the rest of the file name and returns it
function findexts ($filename)
{
$filename = strtolower($filename) ;
$exts = split("[/\\.]", $filename) ;
$n = count($exts)-1;
$exts = $exts[$n];
return $exts;
}
$ext = findexts ($_FILES['picture']['name']) ;
//This assigns the subdirectory you want to save into... make sure it exists!
$target = "mainimage/";
//This combines the directory, the random file name, and the extension
$target = $target . $id.".".$ext;
if(move_uploaded_file($_FILES['picture']['tmp_name'], $target))
{
echo ("This is your new profile picture!");
}
else
{
echo "Sorry, there was a problem uploading your file.";
}
for some reason the "else" keeps showing up (there was a problem uploading the file). I put comments in everything that I am trying to do. please help! thanks!
To close the question as per OP's request.
The issue is that you need to increase the maximum size for uploads. PHP's default is usually 2M and you are most probably trying to upload a file larger than what the maximum setting is set to.
This can be achieved in two ways.
By editing your php.ini file with the following settings:
; Maximum allowed size for uploaded files.
upload_max_filesize = 40M
; Must be greater than or equal to upload_max_filesize
post_max_size = 40M
or via an .htaccess file placed in the root of your server:
php_value upload_max_filesize 20M
php_value post_max_size 30M
