我想编写函数来将excel文件上传到sql db。
我有一个问题,因为$this->upload->do_upload('file')
没有执行,我无法弄清楚原因。
这是我的控制器:
function import(){
$this->breadcrumbs[] = array(
"title" => "Import",
"link" => "interview/import"
);
$this->template->load("interview_import", $this->breadcrumbs, $data);
}
function import_data() {
$this->load->library("form_validation");
$config = array(
'upload_path' => FCPATH. 'upload/',
'allowed_types' => 'xls'
);
$this->load->library('upload', $config);
if($this->upload->do_upload('file')) {
$data = $this->upload->data();
@chmod($data['full_path'], 0777);
}
$this->load->library("Spreadsheet_Excel_Reader");
$this->spreadsheet_excel_reader->setOutputEncoding('CP1251');
$this->spreadsheet_excel_reader->read($data['full_path']);
$sheets = $this->spreadsheet_excel_reader->sheets[0];
error_reporting(E_ALL ^ E_NOTICE);
$data_excel = array();
for ($i = 2; $i <= $sheets[0]['numRows']; $i++) {
if ($sheets['cells'][$i][1] == '') {
break;
}
$data_excel[$i -1]['name'] = $sheets['cells'][$i][1];
$data_excel[$i -1]['phone'] = $sheets['cells'][$i][2];
$data_excel[$i -1]['address'] = $sheets['cells'][$i][3];
/*for ($j = 1; $j <= $data->sheets[0]['numCols']; $j++) {
echo "\"".$data->sheets[0]['cells'][$i][$j]."\",";
}
echo "\n";*/
}
echo '<pre>';
print_r($data_excel);
echo '</pre>';
die();
}
这是我的观点:
<?php
echo form_open_multipart('interview/import_data');
echo form_upload('file');
echo '<br/>';
echo form_submit(null, 'Upload');
echo form_close();
?>
你知道我做错了什么吗?
尝试上传时收到错误消息:
&GT;遇到PHP错误 严重性:注意 消息:未定义的变量:数据 文件名:controllers / Interview.php 行号:521 回溯: 文件:C:\ Users \ A66155193 \ Desktop \ xampp \ htdocs \ yitt \ application \ controllers \ Interview.php 行:521 功能:_error_handler 文件:C:\ Users \ A66155193 \ Desktop \ xampp \ htdocs \ yitt \ index.php 行:311 功能:require_once
显然if子句可以执行,因为:
未定义的变量:数据
感谢您的帮助!
答案 0 :(得分:0)
如果do_upload的条件检查文件是否上传而不是错误
if($this->upload->do_upload('file')) {
$data = $this->upload->data();
@chmod($data['full_path'], 0777);
} else{
$error = array('error' => $this->upload->display_errors());
print_r($error);
}
你必须检查它,因为$ data变量在if语句中初始化,而在底部则表示取消定义变量。
