在Yii2中导入CSV

Question

我做了什么？

我试图在项目模块中上传csv文件。csv格式如下。在上传时，出现错误消息“ 1 Row has Validation Error”。 值未插入db中。

我想要的是？

我想在mysql数据库中上传csv文件数据。

      **My CSV Format**
==============================================================================
model_name|imei_no|promoter_vendor_id|device_report_id|allocation_date
==============================================================================
sam       | 2342  |     7            |   3             |2015
==============================================================================

插入查询MySQL

INSERT INTO `dbname`.`tbl_device`
(`device_id`,`model_name`,`imei_no`,`promoter_vendor_id`,`device_report_id`,
`allocation_date`,`inserted_date`,`inserted_ip`,`inserted_by`,`updated_date`,
`updated_ip`,`updated_by`,`status_in`,`record_status`)VALUES
(Auto_inc,sam,34234,7,3,2015,?,?,?,?,?,?,?,?);

模型导入功能

In model i am trying to create insert query in yii model.

    //Check the file available or not

    if(file_exists('device_csv.csv')){
    $handle = fopen('device_csv.csv', "r");
        $valueComa='';
    $model_name=$imei_no=$promoter_vendor_id=$device_report_id=$allocation_date=-1;

    while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) 
     {
    $num = count($data);echo "<script>alert(".$num.");</script>";

Answer 1

您可以使用供应商的库。 例如： https : //github.com/ruskid/yii2-csv-importer

Answer 2

根据您发布的MySQL查询， sam周围缺少引号

INSERT INTO `dbname`.`tbl_device` 
(`device_id`, `model_name`, `imei_no`, `promoter_vendor_id`,
`device_report_id`, `allocation_date`, `inserted_date`,
`inserted_ip`, `inserted_by`, `updated_date`, `updated_ip`,
`updated_by`, `status_in`,`record_status`)
VALUES (Auto_inc, 'sam', 34234, 7,3,2015,?,?,?,?,?,?,?,?);

在解析csv行的过程中，您应该创建一个数组$ string标记$string[0]=true; （0是model_name列的索引），如果$string[$c] === true ，则在第二个循环中添加引号。 我不复制/粘贴解决方案，这里有很多代码只需更改2或3行。

希望能帮助到你。
