我正在研究Yii2.我正在导入一个excel文件.导入它时,我也发送了以前型号的ID.过程如下
>用户打开GUI并从下拉列表中选择一些值,然后单击“创建”按钮.
创建控制器
public function actionCreate()
{
$model = new MeterAcceptanceHeader();
$model->prepared_by = Yii::$app->user->id;
$model->prepared_at = date('Y-m-d H:i:s');
if ($model->load(Yii::$app->request->post()) && $model->save()) {
return $this->redirect(['excel','id'=>$model->id]);
} else {
return $this->render('create', [
'model' => $model,
]);
}
}
>点击下一个按钮后,用户将看到一个新窗口,要求他上传excel文件.
Excel控制器
public function actionExcel($id){
$file_name = "excel_" . Yii::$app->user->id . ".xlsx";
$error = "";
if(isset($_FILES['file'])) {
$path_parts = pathinfo($_FILES["file"]["name"]);
$extension = $path_parts['extension'];
if(!in_array($extension,['xlsx','xls'])){
$error = "Invalid file";
}else {
if (move_uploaded_file($_FILES['file']['tmp_name'], 'uploads/' . $file_name)) {
$this->redirect([
'process',
'file_name' => $file_name,
'header_no' => $_POST['header_no'],
'id'=>$id
]);
}
}
}
return $this->render("excel",['error'=>$error,'id'=>$id]);
}
Excel视图
<div class="box-body">
<?php if($error != ""){?>
<div class="alert alert-danger"><?=$error?></div>
<?php } ?>
<form action="" method="post" enctype="multipart/form-data">

>上传excel文件后,用户将单击下一步按钮
>现在,在此窗口中,将要求用户使用DB字段映射excel字段
过程控制器
public function actionProcess(){
$file_name = $_GET['file_name'];
$id = $_GET['id'];
try {
$header_index = $_GET['header_no'];
$data = \moonland\phpexcel\Excel::widget([
'mode' => 'import',
'fileName' => 'uploads/' . $file_name,
'setFirstRecordAsKeys' => false, // if you want to set the keys of record column with first record, if it not set, the header with use the alphabet column on excel.
'setIndexSheetByName' => false, // set this if your excel data with multiple worksheet, the index of array will be set with the sheet name. If this not set, the index will use numeric.
'getOnlySheet' => 0, // you can set this property if you want to get the specified sheet from the excel data with multiple worksheet.
]);
if (isset($data[0])) {
$headers = $data[0][$header_index];
} else {
$headers = $data[$header_index];
}
}catch (Exception $x){
print_r($x->errorInfo);
}
return $this->render('excel_options',['headers'=>$headers,'file_name'=>$file_name,'header_index'=>$header_index,'id'=>$id]);
}

在流程动作控制器中调用上述视图.在这个视图中,我将模型ID作为隐藏字段传递.
>映射文件并单击提交按钮后,文件中的数据将保存到数据库中.下面是将数据保存到数据库中的导入操作
public function actionImport()
{
$file_name = $_POST['file_name'];
$header_index = $_POST['header_index'];
$fieldSet = $_POST['field'];
$model_id = $_POST['model_id'];
print_r($model_id);
die();
.
.
.
return $this->render('excel_finish', ['records_saved' => $ok_count,'status_arr'=>$status_arr]);
}
到目前为止我做了什么
我可以从用户中选择数据(包括excel文件).映射后,它应该转向导入操作,但我得到低于错误
Not Found (#404)
Page not found.
url：http：// localhost：225 / inventory-web / backend / web / meteracceptanceheader / process / import
更新1
在浏览器中检查元素时,我可以看到模型ID.
我一定做错了,我不知道.
任何帮助将受到高度赞赏.
