我一直在抨击这一段时间,似乎一次推进小步骤。我需要为用户提供一种通过Ajax上传文件的方法。我已经看到需要使用formData
来传递文件本身。使用这两个问题作为参考:
Uploading file in Yii using ajax
Yii ajax file upload
我的视图页面上有以下代码:
<?php
$form=$this->beginWidget('CActiveForm', array(
'id'=>'post-form',
'htmlOptions' => array('enctype' => 'multipart/form-data'),
));
echo '<div class="columns small-5">' . $form->fileField($upload, 'image') . '</div>';
echo $form->error($upload, 'image');
echo CHtml::button("(+)",array('title'=>"Topic",'onclick'=>'js:upload_file(this);'));
$this->endWidget(); ?>
<script>
function upload_file(){
var fd = new FormData();
var e = document.getElementById("UploadedFiles_image");
fd.append( "UploadedFiles[image]", $(e)[0].files[0]);
$.ajax({
url: 'UploadInstallPhoto',
type: 'POST',
cache: false,
data: fd,
datatype: 'json',
processData: false,
contentType: false,
success: function (data) {
},
error: function () {
alert("ERROR in upload");
}
});
}
</script>
我的控制器中包含以下代码:
if(Yii::app()->request->isAjaxRequest)
{
$upload = new UploadedFiles;
$upload->attributes = $_POST['UploadedFiles'];
$file = CUploadedFile::getInstance($upload,'image');
$pi = pathinfo($file);
$upload->name = $pi['filename'];
$upload->ext = $pi['extension'];
$upload->acc_id = $id;
$upload->type_id = 1;
$upload->date_uploaded = date('Y-m-d');
if($upload->save())
{
$file->saveAs(Yii::app()->params['uploadFiles'] . $upload->id . '.' . $pi['extension']);
Yii::app()->user->setFlash('success',Yii::t('flash','flash.accounts.successful_upload'));
}
}
使用上面的代码,我现在可以执行ajax文件提交,这是按预期工作的。我现在面临的问题是文件被放入一个文件夹中,并创建了数据库中的一个条目。在DB中我引用了人员帐户,因此可以在该用户的帐户上看到该文件。
我需要做的是使用ajax POST传递一组数据,即
data: {file: fd, id: id}
但是,当我更改线条以使用数组时,不会发布任何数据。请有人建议可能的修复或如何传递多个值,包括文件值。
答案 0 :(得分:1)
这是适合我的解决方案。我现在能够通过Ajax上传文件,并传递多个变量以及文件。
以下是查看页面的代码:
<?php
$form=$this->beginWidget('CActiveForm', array(
'id'=>'post-form',
'htmlOptions' => array('enctype' => 'multipart/form-data'),
));
echo '<div class="columns small-5">' . $form->fileField($upload, 'image') . '</div>';
echo $form->error($upload, 'image');
echo CHtml::button("(+)",array('title'=>"Topic",'onclick'=>'js:upload_file(this);'));
$this->endWidget();
?>
<script>
function upload_file(){
var fd = new FormData();
var e = document.getElementById("UploadedFiles_image");
fd.append( "UploadedFiles[image]", $(e)[0].files[0]);
fd.append( "UploadedFiles[acc_id]", <?php echo $model->account_id; ?>); //This lines appends the required ID, thanks to Adeneo
$.ajax({
url: 'UploadInstallPhoto',
type: 'POST',
cache: false,
data: fd,
datatype: 'json',
processData: false,
contentType: false,
success: function(data){
},
error: function(){
alert("ERROR in upload");
}
});
}
</script>
以下是我的控制器代码:
public function actionUploadInstallPhoto()
{
if(Yii::app()->request->isAjaxRequest)
{
$upload = new UploadedFiles;
$upload->attributes = $_POST['UploadedFiles'];
$file = CUploadedFile::getInstance($upload,'image');
$pi = pathinfo($file);
$upload->name = $pi['filename'];
$upload->ext = $pi['extension'];
$upload->acc_id = $_POST['UploadedFiles']['acc_id'];
$upload->type_id = Yii::app()->params['installPhoto'];
$upload->date_uploaded = date('Y-m-d');
if($upload->save())
{
$file->saveAs(Yii::app()->params['uploadFiles'] . $upload->id . '.' . $pi['extension']);
Yii::app()->user->setFlash('success',Yii::t('flash','flash.accounts.successful_upload'));
}
}
}
希望这会帮助那些和我一样的人。
