将数据 excel 插入 2 个带有 id codeigniter 的表中

Question

我遇到了如何使用 phpsreadsheet 将文件上传到数据库的问题。我想将数据放入两个表中：

1. Beasiswa 包含表格：beasiswa_nama、beasiswa_id、beasiswa_file（链接文件）、beasiswa_tahun、DATE_CREATED、DATE_UPDATED。
2. data_mahasiswa 餐桌：id_mhs, nama_mhs, nim_mhs, (FK) id_beasiswa

如何插入文件并读入Beasiswa表，学生数据读入data_mahasiswa？

关系表：

错误创建数据：

Answer 1

这是因为您在data_mahasiswa 表中插入了空数据，可能会发生外键错误。

在foreach ($sheet as $row) 中使用的 Excel 中有空白空间（可能已被编辑？）。您可以通过以下方式解决此问题：

foreach ($sheet as $row) {
    if ($numRow > 3) {
         if($row['A'] != null && $row['B'] != null)
         {
             $dataExcel[] = array(
                 'nama_mhs' => $row['A'],
                 'nim_mhs' => $row['B']
             );
         }
         /*you can also break the function, if no empty row between data in your excel*/
         /*else
         {
             break;
         }*/
    }
}

Answer 2

当你将数据输入数据库时​​，你需要去掉空值。在 Beasiswa Controller

的这行代码上方

$this->db->insert_batch('data_beasiswa', $dataExcel);

添加这行代码删除有空数据的单元格

foreach ($dataExcel as $data => $val) {
    if(empty($val['nama_mhs'])){
        unset($dataExcel[$data]['nama_mhs']);
        unset($dataExcel[$data]['nim_mhs']);                
    }
}
$dataExcel = array_filter($dataExcel);
$data = array('data_excel' => $dataExcel);
