Если я хочу изменить свое имя файла, прежде чем он перейдет на сервер для его постоянного местоположения, а не его временное местоположение, как я могу это сделать.
Код выглядит следующим образом:
<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> <?php if ((($_FILES["file"]["type"] == "image/gif") || ($_FILES["file"]["type"] == "image/jpeg") || ($_FILES["file"]["type"] == "image/pjpeg")) && ($_FILES["file"]["size"] < 20000)) { if ($_FILES["file"]["error"] > 0) { echo "Return Code: " . $_FILES["file"]["error"] . "<br />"; } else { echo "Upload: " . $_FILES["file"]["name"] . "<br />"; echo "Type: " . $_FILES["file"]["type"] . "<br />"; echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />"; echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br />"; if (file_exists("upload/" . $_FILES["file"]["name"])) { echo $_FILES["file"]["name"] . " already exists. "; } else { move_uploaded_file($_FILES["file"]["tmp_name"], "upload/" . $_FILES["file"]["name"]); echo "Stored in: " . "upload/" . $_FILES["file"]["name"]; } } } else { echo "Invalid file"; } ?> Я не уверен, понимаю ли вы, что вы имеете в виду. Если вы просто хотите переименовать файл при его хранении в каталоге «загрузить», сделайте это при использовании move_uploaded_file() :
$destination = "upload/" . $new_filename; if (file_exists($destination)) { echo 'File ', $destination, ' already exists!'; } else { move_uploaded_file($temp_filename, $destination); }
Вы также можете позволить пользователю определить $new_filename , предоставив дополнительное текстовое поле «переименовать» в вашей HTML-форме.
EDIT : Код может быть примерно таким:
Форма:
<form action="upload_file.php" method="post" enctype="multipart/form-data"> <label for="file">Filename:</label> <input type="file" name="file" id="file" /> <br /> <!-- NEW TEXTBOX --> <label for="newname">Rename to (optional):</label> <input type="text" name="newname" id="newname" /> <br /> <input type="submit" name="submit" value="Submit" /> </form>
PHP:
$upload_dir = realpath('upload') . DIRECTORY_SEPARATOR; $file_info = $_FILES['file']; // Check if the user requested to rename the uploaded file if (!empty($_POST['newname'])) { $new_filename = $_POST['newname']; } else { $new_filename = $file_info['name']; } // Make sure that the file name is valid. if (strpos($new_filename, '/') !== false || strpos($new_filename, '\\') !== false) { // We *have* to make sure that the user cannot save the file outside // of $upload_dir, so we don't allow slashes. // ATTENTION: You should do more serious checks here! die("Invalid filename"); } $destination = $upload_dir . $new_filename; // ... if (file_exists(... move_uploaded_file(...
вы делаете это в функции move_uploaded_file
move_uploaded_file($temporary_file, "path/to/destination/and/new_file_name.gif");
прямо сейчас, вы просто перемещаете его в пункт назначения с его текущим именем.
public static function uploadFile($filepath="upload",$uniq=0){ global $_FILES; try { // Undefined | Multiple Files | $_FILES Corruption Attack // If this request falls under any of them, treat it invalid. if ( !isset($_FILES['uploaded_file']['error']) || is_array($_FILES['uploaded_file']['error']) ) { $result["status"]="fail";$result["errors"]=('Invalid parameters.');return $result; } // Check $_FILES['uploaded_file']['error'] value. switch ($_FILES['uploaded_file']['error']) { case UPLOAD_ERR_OK: break; case UPLOAD_ERR_NO_FILE: $result["status"]="fail";$result["errors"]=('No file sent.');return $result; case UPLOAD_ERR_INI_SIZE: case UPLOAD_ERR_FORM_SIZE: $result["status"]="fail";$result["errors"]=('Exceeded filesize limit.');return $result; default: $result["status"]="fail";$result["errors"]=('Unknown errors.');return $result; } // You should also check filesize here. if ($_FILES['uploaded_file']['size'] > 1000000) { $result["status"]="fail";$result["errors"]=('Exceeded filesize limit.');return $result; } // DO NOT TRUST $_FILES['uploaded_file']['mime'] VALUE !! // Check MIME Type by yourself. $finfo = new finfo(FILEINFO_MIME_TYPE); if (false === $ext = array_search( $finfo->file($_FILES['uploaded_file']['tmp_name']), array( 'jpg' => 'image/jpeg', 'png' => 'image/png', 'gif' => 'image/gif', ), true )) { $result["status"]="fail";$result["errors"]=('Invalid file format.');return $result; } if($uniq==0){ $temp=$filepath; } else{ $temp=$filepath."/".uniqid()."_".$_FILES['uploaded_file']['name']; } if(@copy($_FILES['uploaded_file']['tmp_name'], $temp)) { return $result["status"]="success"; } $result["status"]="fail";$result["errors"]=('Unknown errors.');return $result; } catch (Exception $e) { $result["status"]="fail";$result["errors"]= $e->getMessage();return $result; } }
//form submit in database and file store in the documents folder $target_dir = "assets/documents/"; $target_file = $target_dir . basename($_FILES["imageUpload"]["name"]); $uploadOk = 1; $imageFileType = pathinfo($target_file,PATHINFO_EXTENSION); if (move_uploaded_file($_FILES["imageUpload"]["tmp_name"], $target_file)) { } $images = basename($_FILES["imageUpload"]["name"],"");
