Image upload failing in PHP - php

So I'm trying to set up an image upload from a form via php on my localhost and after running the code and connecting to the database okay, I'm getting the error for the upload. Since all of the other parts of the form are working after a section by section check, I'll just add the html for the upload input and its relevant php script.
<input type="file" name="image" id="image-select" />
And the portion of the php that has to deal with the image upload and verification after upload:
$image = $_FILES ['image']['name'];
$type = #getimagesize ($_FILES ['image']['tmp_name']);
//Never assume image will upload okay
if ($_FILES['image']['error'] !== UPLOAD_ERR_OK) {
die("Upload failed with error code " . $_FILES['image']['error']);
}
//Where the file will be placed
$target_path = "uploads/";
// Add the original filename to target path
$path= $target_path . basename($image);
// Check if the image is invalid before continuing
if($type === FALSE || !($type[2] === IMAGETYPE_TIFF || $type[2] === IMAGETYPE_JPEG || $type[2] === IMAGETYPE_PNG)) {
echo '<script "text/javascript">alert("This is not a valid image file!")</script>';
die("This is not a valid image file!");
} else {
move_uploaded_file($_FILES['image']['tmp_name'], $path);
}
So error appears once the code hits the upload process. I was attempting to upload a small PNG file The relevant code I added is also in their respective orders when they appear in the script.

can you please put error here. If error means that after submit page file is not being upload. then please check your form enctype. see below an example
<form action="" method="post" enctype="multipart/form-data">
<input type="file" name="image" id="image-select" />
<input type="submit" value="Submit">
</form>

Just a wild stab in the dark here as you haven't provided your form tag but you have remembered the enctype attribute haven't you?
Sorry I don't have 50 reputation otherwise I would ask this as a comment.
<form enctype='multipart/form-data' action=''>
<input type="file" name="image" id="image-select" />
</form>
Also you should check if the file uploaded OK before calling getimagesize() (not that this would be the source of your issue)

if you are using PHP5 and Imagick, then you can try to use something like the following:
$image->readImageFile($f);

How to check if $_POST[image] is set

Re asking how to check if $_POST[FILE] isset
I have a file input and if I submit my form without an image I want something to happen if I uploaded a file in the input I want something different to happen.
if (!isset($_POST[image])) { }
seems to trigger regardless of whether or not I have uploaded a file in the input or not.
<label>
<p>Profile Picture:</p>
<input type="file" name="image" value="" />
</label>
My last question was marked as a duplicate of this answer Check whether file is uploaded however
if (!file_exists($_FILE['image'])) { }
didn't work either it is still showing truthy even when an image is uploaded. So not the answer I need.
To check if there is a file uploaded is you need to check the size of the file.
Then to check if its an image or not is you need to use the getimagesize() function. See my script below:
HTML:
<form action="index.php?act=s" method="post" enctype="multipart/form-data">
<input type="file" name="image" value=""/>
<input type="submit">
</form>
PHP:
<?php
if(isset($_GET['act'])){
// Check if there is a file uploaded
if($_FILES["image"]["size"]>0){
echo "There is a file uploaded<br>";
// Check if its an image
$check_if_image = getimagesize($_FILES["image"]["tmp_name"]);
if($check_if_image !== false) {
echo "Image = " . $check_if_image["mime"] . ".";
} else {
echo "Not an image";
}
}
else{
echo "There is NO file uploaded<br>";
}
}
?>

Using HTML POST to upload file via PHP

I am trying to upload a local file to webserver using HTML POST method and PHP.
this is my php code:
<?php
if (isset($_POST["submit"])) {
$updir = "/var/tmp/";
$upfile = $updir.basename($_FILES['rawexcel']['name']);
if(is_uploaded_file ($_FILES ["rawexcel"]["tmp_name"]))
{
move_uploaded_file ($_FILES["rawexcel"]["tmp_name"], $upfile);
} else {echo "error uploading file ".$upfile;}
} else {echo "not isset post method";}
?>
and HTML code is:
<div class="container" id="upl">
<h4> Upload files</h4>
<form action="upl.php" enctype="mutipart/form-data" method="post">
<p> upload your files to DB</p>
<p><input type="file" name="rawexcel" id ="rawexcel">
<input type ="submit" value="Upload" name ="submit"></p>
</form>
</div>
$_FILES["rawexcel"]["error"] shows 0 and from running this peice of code i get
error uploading file /var/tmp
I guess file name was not retrieved from html?
Error is in enctype:
enctype="multipart/form-data"
not:
enctype="mutipart/form-data"
You have typo mistake in enctype="multipart/form-data" , instead of this you typed enctype="mutipart/form-data" . So "mutipart" spelling is need to correct.

Image not uploading to web server

I am having some difficulty uploading an image to a folder on my web server. Here's my code:
HTML:
<form action="" method="POST" enctype="multipart/form-data">
<input type="file" name="image">
<input type="submit" value="Upload Image" name="upload">
</form>
PHP:
<?php
if (isset($_POST["upload"])) {
$name = $_FILES["image"]["name"];
$type = $_FILES["image"]["type"];
$size = $_FILES["image"]["size"];
$temp = $_FILES["image"]["tmp_name"];
$error = $_FILES["image"]["error"];
$target_file = "/profiles/images/$name";
move_uploaded_file($temp, $target_file);
}
?>
I've tried echoing out the file name ($name), but it doesn't return anything at all. It's blank for some reason. This is when I try to upload an image. When I echo $target_file, I get this "/profiles/images/", the $name part is not included for some reason.
Check your max upload file size. If in the settings the size is smaller than the file you are trying to upload, nothing is send.
This is happens in those cases when we try to upload very heavy size image, Please try to check your maximum file size, and please for testing try to upload maximum 100kb size of pic through this code. Hope this will work.

Uploading files on Server

I am writing an app from which user will upload files on the server. I have found a php script from internet but I don't know how am I going to tell the script where to upload the data. This might be a silly question but I am no PHP programmer. I am using this php script in my java code.
Here is the script.
<?php
$filename="abc.xyz";
$fileData=file_get_contents('php://input');
echo("Done uploading");
?>

This is a terrible way of uploading files, you are much better off using a form and the $_FILES superglobal.
Take a look at the W3Schools PHP File Upload Tutorial; please read all of it. For further reading take a look at the PHP Manual pages on file upload.
The file input type will create the upload box in the html form:
<form action="upload_file.php" method="post"
enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="file" id="file"><br>
<input type="submit" name="submit" value="Submit">
</form>
After error checking and validating that the file is what you are expecting (very important: allowing users to upload anything to your server is a huge security risk), you can move the uploaded file to your final destination on the server in PHP.
move_uploaded_file($_FILES["file"]["tmp_name"], "upload/abc.xyz");
The filename is actualy the file path along with the name of the new file, set the path there and a file will be created with write permissions.
Make sure you give the servers full path not the relative one and that you have the required permission to create a file there.
Always refer to the PHP Manual
Here's a basic example to get you started:
HTML:
<html>
<body>
<form enctype="multipart/form-data" action="upload.php" method="post">
<input type="hidden" name="MAX_FILE_SIZE" value="1000000" />
Choose a file to upload: <input name="uploaded_file" type="file" />
<input type="submit" value="Upload" />
</form>
</body>
</html>
PHP:
<?php
//Сheck that we have a file
if((!empty($_FILES["uploaded_file"])) && ($_FILES['uploaded_file']['error'] == 0)) {
//Check if the file is JPEG image and it's size is less than 350Kb
$filename = basename($_FILES['uploaded_file']['name']);
$ext = substr($filename, strrpos($filename, '.') + 1);
if (($ext == "jpg") && ($_FILES["uploaded_file"]["type"] == "image/jpeg") &&
($_FILES["uploaded_file"]["size"] < 350000)) {
//Determine the path to which we want to save this file
$newname = dirname(__FILE__).'/upload/'.$filename;
//Check if the file with the same name is already exists on the server
if (!file_exists($newname)) {
//Attempt to move the uploaded file to it's new place
if ((move_uploaded_file($_FILES['uploaded_file']['tmp_name'],$newname))) {
echo "It's done! The file has been saved as: ".$newname;
} else {
echo "Error: A problem occurred during file upload!";
}
} else {
echo "Error: File ".$_FILES["uploaded_file"]["name"]." already exists";
}
} else {
echo "Error: Only .jpg images under 350Kb are accepted for upload";
}
} else {
echo "Error: No file uploaded";
}
?>
Refer to the documention for more information.
Hope this helps!

uploading file to folder on website via PHP

I would like to have the user upload a pdf to a folder on my website. (note:this is for learning purposes, so security is not necessary) The code I have below does not do echo a response when submitted. The folder I would like to have the pdf uploaded to is in the same directory as the php script, is it possible I'm incorrectly referencing that folder? I appreciate it.
<form method = "POST" action = "<?php echo $_SERVER['PHP_SELF']; ?>" enctype="multipart/form-data" method="post">
Email:<br /> <input type = "text" name="email" value=""/><br />
Resume:<br /><input type = "file" name="resume" value=""/><br />
<p><input type="submit" name ="submit" value="Submit Resume" /></p>
</form>
if(isset($_POST['submit']))
{
define ("FILEREPOSITORY","./resume/");
if (is_uploaded_file($_FILES['resume']['tmp_name'])) {
if ($_FILES['resume']['type'] != "application/pdf") {
echo "<p>Resume must be in PDF Format.</p>";
}
}else {
$name = $_POST['email'];
$result = move_uploaded_file($_FILES['resume']['tmp_name'], FILEREPOSITORY."/$name.pdf");
if ($result == 1) {
echo "<p>File successfully uploaded.</p>";
}
else {
echo "<p>There was a problem uploading the file.</p>";
}
}
}
You have a logical error. Your else statement should be part of the inner if statement -- not the outer one.
would suggest you check the permissions for the upload folder and the max size for file uploading in your php.ini... its happened to me many times uploading a file exceeding the limits and not getting an error message.. also the logic of your if else doesn't match as suggested by your previous post..
IT would be of great help to give the error you receive.
move_uploaded_file()
only works if you have the rights to write to the destination folder.
