Hi all ! I have been experimenting with a bit of code that uploads file to the server. The image is previewed once selected and can then be uploaded. The uploaded image is then selected and displayed. Here is the code usp5.php <?php error_reporting(E_ALL); require_once 'DB.php'; $uploaddir = 'D:/xampp/php/internals/uploads/'; # Outside of web root // echo $uploadfile."<br>"; // exit(); if(isset($_POST['upload'])) { $blob = "BLOB"; $filename = $_FILES['userfile']['name']; $filetype = $_FILES['userfile']['type']; $tmp_filename = $_FILES['userfile']['tmp_name']; $uploadfile = tempnam($uploaddir, "upm"); if (move_uploaded_file($tmp_filename, $uploadfile)) { try { $query = "INSERT INTO images (name, original_name, mime_type, images) VALUES (?,?,?,?)"; $stmt = $link->prepare($query); $stmt->bind_param('ssss',$uploadfile,$filename,$filetype,$blob); if($stmt->execute()){ $id=$stmt->insert_id; // get the just inserted id } else{ echo "Error : ".$link->error; } } catch(mysqli_sql_exception $imageException) { if ($imageException->getCode() === MYSQL_ER_DUP_ENTRY) { echo'The filename is already taken, please choose a different name.'; return false; } else { // rethrow exception throw $imageException; } } } if(!is_numeric($id)) { die("File id must be numeric"); } $query = 'SELECT name, mime_type FROM images WHERE id=?'; $stmt = $link->prepare($query); $stmt->bind_param('i',$id); $stmt->execute(); $stmt->bind_result($filename,$type); $stmt->store_result(); $stmt->fetch(); $stmt->free_result(); if(is_null($filename) || count($filename)===0) { die("File not found"); } header("Content-Type: " . $type); // echo "<div class='div2'>"; // works good without the div. Divs cause the binary dump to show instead echo '<img src="'.readfile($filename).'"alt="">'; // echo "</div>"; } ?> <html> <head> <title>File Upload To Database</title> <link class="jsbin" href="https://ajax.googleapis.com/ajax/libs/jqueryui/1.12.1/themes/smoothness/jquery-ui.css" rel="stylesheet" type="text/css" > <link rel="stylesheet" type="text/css" media="screen" href="divs.css" /> <script class="jsbin" src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script> <script class="jsbin" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.0/jquery-ui.min.js"></script> <meta charset=utf-8 /> </head> <body> <form name="upload" action="#" method="POST" enctype="multipart/form-data"> Select the file to upload: <br> <input type="file" name="userfile" onchange="readURL(this)"; /><br> <br><input type="submit" name="upload" value="Upload"> <div class = "div1"> <img id="image" src="#" alt="load image" /> <!-- This displays the image. --> </div> </form> <!-- <img class="div2" src="'<?php // readfile($filename); ?>'" alt="load image" /> --> <script> function readURL(input) { if (input.files && input.files[0]) { var reader = new FileReader(); reader.onload = function (e) { $('#image') .attr('src', e.target.result) .width(200) .height(200); }; reader.readAsDataURL(input.files[0]); }else{ alert( "File not selected or browser incompatible." ); } } </script> </body> </html> divs.css .div1 { height:220px; width: 220px; display:block; margin:5px; border:1px solid navy; background-color:#ffffbb; } .div2 { height:350px; width: 350px; display:block; margin-left:1px; border:1px solid navy; background-color:#ffaaff; } img{ max-width: 100%; max-height: 100%; } In the first preview, before upload, a bigger image is automatically reduced to fit into a 200px by 200px due to the width and height set in the jquery. After the image is loaded on the server and is selected using the id of the image, I am unable to fit the same in a div to restrict the size of the image to any arbitrary given dimensions. Kindly help me with that. Is it possible to display both the images simultaneously in two separate divs ? How ? Any security issues in this ? Thanks all !

I am using a simple image upload. http://www.w3schools.com/php/php_file_upload.asp It gives me 2 errors like this. Warning: move_uploaded_file(C:/xampp/htdocs/home/upload/images/grandpix 2.jpg): failed to open stream: No such file or directory in C:\xampp\htdocs\home\upload\post.php on line 174 Warning: move_uploaded_file(): Unable to move 'C:\xampp\tmp\phpF915.tmp' to 'C:/xampp/htdocs/home/upload/images/grandpix 2.jpg' in C:\xampp\htdocs\home\upload\post.php on line 174 This is my code. Post.php . I see that it's the "$target_dir" issue. How can I fix it? if(isset($_FILES['fileToUpload'])){ if(!empty($_FILES['fileToUpload']['name'])) { $target_dir = $_SERVER['DOCUMENT_ROOT'].'/home/upload/images/'; $target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]); $uploadOk = 1; $imageFileType = pathinfo($target_file,PATHINFO_EXTENSION); $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]); if($check !== false) { $uploadOk = 1; } else { $errors[] = 'File is not an image.'; $uploadOk = 0; } // Check if file already exists if (file_exists($target_file)) { $errors[] = 'Sorry, file already exists.'; $uploadOk = 0; } // Check file size if ($_FILES["fileToUpload"]["size"] > 500000) { $errors[] = 'Sorry, your file is too large.'; $uploadOk = 0; } // Allow certain file formats if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg" && $imageFileType != "gif" ) { $errors[] = 'Sorry, only JPG, JPEG, PNG & GIF files are allowed.'; $uploadOk = 0; } // Check if $uploadOk is set to 0 by an error if ($uploadOk == 0) { $errors[] = 'Sorry, your file was not uploaded.'; // if everything is ok, try to upload file } else { if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) { echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded."; } else { $errors[] = 'Sorry, there was an error uploading your file.'; } } $insert_image = $db->prepare("INSERT INTO images(user_id, item_id, image_path, date_added) VALUES(:user_id, :item_id, :image_path, :date_added)"); $insert_image->bindParam(':user_id', $userid); $insert_image->bindParam(':item_id', $item_id); $insert_image->bindParam(':image_path', $target_file); $insert_image->bindParam(':date_added', $date_added); if(!$insert_image->execute()) { $errors[] = 'There was a problem uploading the image!'; } else { if(empty($errors)) { $db->commit(); $success = 'Your post has been saved.'; } else { $db->rollBack(); } } } else { $errors[] = 'An image is required!'; } }
