使用codeigniter从excel表导入数据

我想把excel表格的sing列导入到数据库表名admin_record中，excel表只包含一列，列名是条形码，行可以多。

我想把它保存在数据库中，我的表名是admin_record，它只包含两个字段

1. id（这是主键）
2. 条码。

只find这个我完全不能理解的代码

public function read_file($table = 'admin_record', $filename = 'example.xls') { $pathToFile = 'uploads/' . $filename; $this->load->library('Spreadsheet_Excel_Reader'); $data = new Spreadsheet_Excel_Reader($pathToFile); $sql = "INSERT INTO $table ("; for($index = 1;$index <= $data->sheets[0]['numCols']; $index++){ $sql.= strtolower($data->sheets[0]['cells'][1][$index]) . ", "; } $sql = rtrim($sql, ", ")." ) VALUES ( "; for ($i = 2; $i <= $data->sheets[0]['numRows']; $i++) { $valuesSQL = ''; for ($j = 1; $j <= $data->sheets[0]['numCols']; $j++) { $valuesSql .= "\"" . $data->sheets[0]['cells'][$i][$j] . "\", "; } echo $sql . rtrim($valuesSql, ", ")." ) <br>"; } }

您的库文件错误，请使用以下链接下载Spreadsheet_Excel_Reader库

 public function my_test($table = 'admin_record', $filename = 'resources/uploads/c.xls') { $pathToFile = $filename; $valuesSql=""; $this->load->library('Spreadsheet_Excel_Reader'); $data = new Spreadsheet_Excel_Reader($pathToFile); $sql = "INSERT INTO $table ("; for($index = 1;$index <= $data->sheets[0]['numCols']; $index++){ $sql.= strtolower($data->sheets[0]['cells'][1][$index]) . ", "; } $sql = rtrim($sql, ", ")." ) VALUES ( "; for ($i = 2; $i <= $data->sheets[0]['numRows']; $i++) { $valuesSQL = ''; for ($j = 1; $j <= $data->sheets[0]['numCols']; $j++) { $valuesSql .= "\"" . $data->sheets[0]['cells'][$i][$j] . "\", "; } echo $sql . rtrim($valuesSql, ", ")." ) <br>"; } // add this line }
