先跟大家介紹一下html5中file的multiple屬性
定義和用法
multiple 屬性規定輸入欄位可選擇多個值。如果使用該屬性,則欄位可接受多個值。
實例:
<form action="demo_form.asp" method="get"> Select images: <input type="file" name="img" multiple="multiple" /> <input type="submit" /> </form>
上面實例中的input file 可接受多個檔案上傳欄位。
了解了html5中file的multiple屬性,下面我們開始講解使用html5實作多檔案上傳。
實例代碼:
html:
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> </head> <body> <form action="my_parser.php" method="post" enctype="multipart/form-data"> <p><input name="upload[]" type="file" multiple="multiple" /></p> <input type="submit" value="Upload all files"> </form> </body> </html>
php代碼:
for($i=0; $i<count($_FILES['upload']['name']); $i++) { //Get the temp file path $tmpFilePath = $_FILES['upload']['tmp_name'][$i]; //Make sure we have a filepath if ($tmpFilePath != ""){ //Setup our new file path $newFilePath = "./uploadFiles/" . $_FILES['upload']['name'][$i]; //Upload the file into the temp dir if(move_uploaded_file($tmpFilePath, $newFilePath)) { //Handle other code here } } }
