I have a web page that lets user upload their profile photo. The PHP script works, but sometimes it just wont upload the photo. It will even give you a success message that the image was uploaded but it wont add the filename to the database nor will it save the file on the server. If you keep trying to upload the same image for couple more times then it will work and upload the photo. So i need some help in debugging it. Where am i going wrong? I am also using this thumb_function.php file which i got from internet, it basically saves thumbnails in a seperate folder, it works fine. Here is the PHP script that i am using. // Check if the button was clicked or not and process the profile updation if(isset($_POST['btnphoto'])){ include('php/thumb_function.php'); $filename = $_FILES["txtphoto"]["name"]; $newfilename = sha1($userid.$email); $extension = substr(strrchr($filename,'.'),1); $newfilename = $newfilename.".".$extension; $allowedExts = array("jpg", "jpeg", "gif", "png"); if ((($_FILES["txtphoto"]["type"] == "image/gif") || ($_FILES["txtphoto"]["type"] == "image/jpeg") || ($_FILES["txtphoto"]["type"] == "image/png")) && ($_FILES["txtphoto"]["size"] < 1048576) && in_array($extension, $allowedExts)){ if ($_FILES["txtphoto"]["error"] > 0){ $msg = "Error: " . $_FILES["file"]["error"] . "<br>"; } else { $path="../photos/".$newfilename; // the path with the file name where the file will be stored, upload is the directory name. if(move_uploaded_file ($_FILES["txtphoto"]["tmp_name"],$path)){ if ($stmt = $mysqli->prepare("UPDATE student_profile SET photo = ? WHERE user_id = ?")) { // Bind the variables to the parameter as strings. $stmt->bind_param("si", $newfilename, $userid); // Execute the statement. $stmt->execute(); // Close the prepared statement. $stmt->close(); } $msg = 'Your Photo has been updated... '; } else { $msg = 'Failed to upload file Contact Site admin to fix the problem'; exit; } $file = $newfilename; $save = $file; $t_w = 100; $t_h = 100; $o_path = "../photos/"; $s_path = "../photos/thumbnails/"; Resize_Image($save,$file,$t_w,$t_h,$s_path,$o_path); } } else { $msg = 'File is of a wrong type or too heavy.'; } } Here is the HTML form code.. <form name="frmphoto" method="post" action="" enctype="multipart/form-data"> <table border="0" cellpadding="5" cellspacing="5"> <tr><td>Upload Profile Photo : </td></tr> <tr><td><input type="file" name="txtphoto" size="45"></td></tr> <tr><td><input type="submit" name="btnphoto" value="Update Photo"></td></tr> </table> </form>
