ajax檔案上傳

之前有做過圖片上傳，把遇到的事情記下來

用post方式傳檔案

<input type="file" name="myfile">

我後端用PHP抓不到

$_FILES["myfile"]["name"]

換這樣

<input type="file" id="myfile">

就抓的到了

居然是吃ID(是我見鬼嗎)，這樣對嗎?



換ajax傳檔案

<input type="file" id="myfile">

我後端用PHP抓不到

$_FILES["myfile"]["name"]

換這樣

<input type="file" name="myfile">

換這樣就抓的到了

變正常吃NAME了

$("form").submit(function(e) {

e.preventDefault();

var formData = new FormData(this);

$.ajax({

url: '/123.php',

type: 'POST',

data: formData,

success: function (data) {

},

cache: false,

contentType: false,

processData: false

});

});

這樣欺負我QQajax傳檔案用formData來做

要注意:

through FormData object, but unfortunately it is not supported by all/old browsers.FormData support starts from following desktop browsers versions. IE 10+, Firefox 4.0+, Chrome 7+, Safari 5+, Opera 12+
