1.准备工作
下载PHPExcel：http://phpexcel.codeplex.com
这是个强大的Excel库,这里只演示导出Excel文件的功能,其中的大部分功能可能都用不着.
2. 安装PHPExcel到Codeigniter
1） 解压压缩包里的Classes文件夹中的内容到applicationlibraries目录下,目录结构如下:
-- applicationlibrariesPHPExcel.php
-- applicationlibrariesPHPExcel (文件夹)
2）修改applicationlibrariesPHPExcelIOFactory.php 文件
-- 将其类名从PHPExcel_IOFactory改为IOFactory,遵从CI类命名规则.
-- 将其构造函数改为public
3. 安装完毕,写一个导出excel的控制器(Controller),代码如下:
db->get($table_name); if (!$query) return false; // Starting the PHPExcel library $this->load->library('PHPExcel'); $this->load->library('PHPExcel/IOFactory'); $objPHPExcel = new PHPExcel(); $objPHPExcel->getProperties()->setTitle("export")->setDescription("none"); $objPHPExcel->setActiveSheetIndex(0); // Field names in the first row $fields = $query->list_fields(); $col = 0; foreach ($fields as $field) { $objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, 1, $field); $col++; } // Fetching the table data $row = 2; foreach ($query->result() as $data) { $col = 0; foreach ($fields as $field) { $objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, $row, $data->$field); $col++; } $row++; } $objPHPExcel->setActiveSheetIndex(0); $objWriter = IOFactory::createWriter($objPHPExcel, 'Excel5'); // Sending headers to force the user to download the file header('Content-Type: application/vnd.ms-excel'); header('Content-Disposition: attachment;filename="Products_' . date('dMy') . '.xls"'); header('Cache-Control: max-age=0'); $objWriter->save('php://output'); } } ?>
方法二,代码如下:
Excel Plugin The following plugin will generate a tab-delimited file, and feed it to the client as an Excel file. $this->load->plugin('to_excel'); $this->db->use_table('tablename'); $this->db->select('field1', 'field2'); // run joins, order by, where, or anything else here $query = $this->db->get(); to_excel($query, ['filename']); // filename is optional, without it, the plugin will default to 'exceloutput' So you could run: to_excel($query, 'myfile'); // outputs myfile.xls to_excel($query); // outputs exceloutput.xls // you could also use a model here to_excel($this->model_name->functioncall()); /system/plugins/to_excel_pi.php
field_data(); if ($query->num_rows() == 0) { echo 'The table appears to have no data.
'; } else { foreach ($fields as $field) { $headers.= $field->name . "t"; } foreach ($query->result() as $row) { $line = ''; foreach ($row as $value) { if ((!isset($value)) OR ($value == "")) { $value = "t"; } else { $value = str_replace('"', '""', $value); $value = '"' . $value . '"' . "t"; } $line.= $value; } $data.= trim($line) . "n"; } $data = str_replace("r", "", $data); header("Content-type: application/x-msdownload"); header("Content-Disposition: attachment; filename=$filename.xls"); echo "$headersn$data"; } } ?>
