我正在尝试使用codeigniter框架中的ajax上传文件。我的代码在不使用ajax的情况下工作但是当我使用ajax时,我收到错误消息'Undefined index:picture'in if($ _ FILES ['picture'] ['name'])。
请检查此代码
查看:
<form enctype="multipart/form-data" method="post">
<div class="form-group">
<label for="int">Picture</label>
<input type="file" id="picture" name="picture" class="dropify" data-height="300" />
</div>
</form>
AJAX:
var picture=new FormData( $("#picture")[0] );
var url = "<?php echo site_url('Workscontroller/create_action'); ?>";
$.ajax({
url:url,
data: {"title":title,"caption":caption,"description":description,"kategori":kategori,"picture":picture},
dataType:"JSON",
type:"POST",
mimeType: "multipart/form-data",
contentType: false,
cache: false,
processData:false,
success:function(data){
swal("Berhasil ditambahkan!", "Anda berhasil menambahkan porto folio.", "success")
window.location.replace(data.url);
}
});
控制器:
$this->load->library('upload');
$this->_rules();
$nmfile = "file_".time(); //nama file saya beri nama langsung dan diikuti fungsi time
$config['upload_path'] = './works/'; //path folder
$config['allowed_types'] = 'gif|jpg|png|jpeg|bmp'; //type yang dapat diakses bisa anda sesuaikan
$config['max_size'] = '2048'; //maksimum besar file 2M
$config['max_width'] = '2000'; //lebar maksimum 1288 px
$config['max_height'] = '2000'; //tinggi maksimu 768 px
$config['file_name'] = $nmfile; //nama yang terupload nantinya
$this->upload->initialize($config);
if($_FILES['picture']['name'])
{
if ($this->upload->do_upload('picture'))
{
$gbr = $this->upload->data();
$data = array(
'title' => $this->input->post('title',TRUE),
'caption' => $this->input->post('caption',TRUE),
'description' => $this->input->post('description',TRUE),
'picture' => $gbr['file_name'],
'kategori' => $this->input->post('kategori',TRUE),
);
$this->WorksModel->insert($data);
}
}
else{
}

formData
的参数应该是HTML <form>
元素。通过赋予<form>
id属性,最容易做到这一点。
视图:
<form enctype="multipart/form-data" method="post" id='myForm'>
然后ajax改为
var formData = new FormData($("#myForm")[0]);
在javascript中,您没有显示如何设置title
,caption
,description
和kategori
的值。但它们显然是形式中的其他<input>
元素。您可能不需要单独捕获这些值,因为所有表单输入(包括FILE类型输入)都在var formData
中捕获。这意味着可以从
data
选项
data: {"title":title,"caption":caption,"description":description,"kategori":kategori,"picture":picture},
到
data: formData,
行if($_FILES['picture']['name'])
现在可以正常工作。

//像这样更新
var url =“”;
$就({
网址:网址,
数据: “标题”:标题, “标题”:标题, “说明”:说明书中, “驾驶员学校”:驾驶员学校, “图片”:图像},
数据类型: “JSON”,
键入: “POST”,
mimeType:“multipart / form-data”,
contentType:false,
async:false,
cache:false,
contentType:false,
processData:false,
成功:功能(数据){
swal(“Berhasil ditambahkan!”,“Anda berhasil menambahkan porto folio。”,“成功”)
window.location.replace(data.url);
}
});
