  1. Hi all, I got a error when trying to upload to database. Perhaps someone can help me ? Error: ERROR: Could not able to execute INSERT INTO `Puzzle` (`NamePuzzle`, `image`) VALUES ('', ''). HTML Code: <form action="..upload.php" method="post" enctype="multipart/form-data"> Image: <input type="file" name="image" id="take-picture"><br> Name Puzzle: <input type="text" name="NamePuzzle"><br> <br> <input type="submit" value="Upload Puzzle" name="submit"> </form> PHP Code: <?php include "conn.php"; $target_dir = "../uploads/"; $target_file = $target_dir . basename($_FILES["picture"]["name"]); $uploadOk = 1; $imageFileType = pathinfo($target_file,PATHINFO_EXTENSION); // Check if image file is a actual image or fake image if(isset($_POST["submit"])) { $check = getimagesize($_FILES["picture"]["tmp_name"]); if($check !== false) { echo "File is an image - " . $check["mime"] . "."; $uploadOk = 1; } else { echo "File is not an image."; $uploadOk = 0; } } // Check if file already exists if (file_exists($target_file)) { echo "Sorry, file already exists."; $uploadOk = 0; } // Check file size if ($_FILES["picture"]["size"] > 500000) { echo "Sorry, your file is too large."; $uploadOk = 0; } // Allow certain file formats if($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["picture"]["tmp_name"], $target_file)) { echo "The file ". basename( $_FILES["picture"]["name"]). " has been uploaded."; } else { echo "Sorry, there was an error uploading your file."; } } // Escape user inputs for security $image = mysqli_real_escape_string($link, $_POST['image']); $NamePuzzle = mysqli_real_escape_string($link, $_POST['NamePuzzle']); // attempt insert query execution $sql = "INSERT INTO `Puzzle` (`NamePuzzle`, `image`) VALUES ('$image', '$NamePuzzle')"; if(mysqli_query($link, $sql)){ echo "Records added successfully."; } else{ echo "ERROR: Could not able to execute $sql. " . mysqli_error($link); } // close connection mysqli_close($link); ?>
  2. my next step is to make those 2 canvases overlap with the use of layers.. as I look into this solution, maybe there are some users here who can tell me what the best way is to do this
  3. Thanks for your help! ill have a look into that as for now i managed to make it work just to move all square 1 px to the left and one down.. <script> var can = document.getElementById('blokjes'); var ctx = can.getContext('2d'); var pattern = document.createElement('canvas'); pattern.width = 12; pattern.height = 12; var pctx = pattern.getContext('2d'); pctx.fillStyle = "rgb(0, 0, 0)"; pctx.fillRect(0,0,5,5); pctx.fillRect(6,6,5,5); pctx.fillRect(0,6,5,5); pctx.fillRect(6,0,5,5); var pattern = ctx.createPattern(pattern, "repeat"); ctx.beginPath(); ctx.moveTo(0, 0); ctx.lineTo(500, 0); ctx.lineTo(500, 500); ctx.lineTo(0, 500); ctx.closePath(); ctx.fillStyle = pattern; ctx.fill(); </script>
  4. Hi all, I'm trying to get a grid of black squares but need to make a border that is transparant so i can see the squares instead of just one big black square.. here is my code: <script> var can = document.getElementById('blokjes'); var ctx = can.getContext('2d'); var pattern = document.createElement('canvas'); pattern.width = 20; pattern.height = 20; var pctx = pattern.getContext('2d'); pctx.fillStyle = "rgb(0, 0, 0)"; pctx.fillRect(0,0,10,10); pctx.fillRect(10,10,10,10); pctx.fillRect(0,10,10,10); pctx.fillRect(10,0,10,10); var pattern = ctx.createPattern(pattern, "repeat"); ctx.beginPath(); ctx.moveTo(0, 0); ctx.lineTo(500, 0); ctx.lineTo(500, 500); ctx.lineTo(0, 500); ctx.closePath(); ctx.fillStyle = pattern; ctx.fill(); </script>
