一.前端代码
1).基于Boostrap的BootstrapDialog
/*导入Excel*/ $('#btnExcel_add').click(function () {
// fileName为模板名字
var url = "assessment/template/bkhdepartment_import_dialog.php?ac=" + "<?php echo $ac;?>" + "&fileurl=" + "<?php echo $fileurl;?>"+"&fileName=被考核者";
BootstrapDialog.show({
title:"导入", cssClass: 'select-dialog',
message: $('<div></div>').load(url),
buttons: [{
label: '确 定',
cssClass: 'btn-sm btn-primary',
action: function (dlg) {
var formData = new FormData($("#addExcelForm")[0]);
//ajax上传文件要用此方法
$.ajax({
url: addExcelUrl,
type: 'POST',
data: formData,
async: false,
cache: false,
contentType: false,
processData: false,
success: function (msg) {
var msg = JSON.parse(msg);
//把字符串转成json
if (msg.message == 'success') {
hjmsComponent.msgDialog(msg.date, refresh_form);
} else {
toastr.error(msg.date);
} },
error: function (msg) { alert(msg);
} }); } },
{ label: '关 闭',
cssClass: 'btn-sm btn-link',
action: function (dlg) {
dlg.close();
} }] }) });
2）其中bkhdepartment_import_dialog为：
<form class="form-horizontal" id="addExcelForm" enctype="multipart/form-data">
<div class="modal-body" style="font-family: microsoft yahei;color: #666666;text-align: center;font-size: 14px">
<table style="margin: auto">
<tr>
<td>导入文件:</td>
<td >
<input type="text" size="20" name="upfile" id="upfile" style="border:1px solid #ccc;border- radius: 4px;margin-left: 5px">
<input type="button" value="浏览" onclick="path.click()" style="margin-left:5px;width:45px;border:1px solid #ccc;border-radius: 4px;background:#fff">
<input type="file" id="path" style="display:none" onchange="upfile.value=this.value" name="myfile" accept="application/vnd.ms-excel,application/vnd.openxmlformats-officedocument.spreadsheetml.sheet">
</td>
</tr>
</table>
<div style="padding-top: 20px;font-size: 14px">
<a href="download/附件/Excel导入模板/<?php echo $_GET['fileName'];?>.xlsx" download="<?php echo $_GET['fileName'];?>.xlsx" style="vertical-align: middle">下载导入模板</a>
<span style="padding-left:20px;color: red;vertical-align: middle">注意：支持xls和xlsx格式</span>
</div>
</div>
</form>
二.后端暴露接口
mod_addExcel（）
//判断是否选择了要上传的表格
if (empty($_POST['upfile'])) {
$back = array(
'message' => 'error',
'date' => '上传文件不能为空'
);
echo json_encode($back);
exit();
}
//获取表格的大小，限制上传表格的大小5M
$file_size = $_FILES['myfile']['size'];
if ($file_size > 5 * 1024 * 1024) {
$back = array(
'message' => 'error',
'date' => '文件大小不能超过5M'
);
echo json_encode($back);
exit();
// echo '文件大小不能超过5M';
}
//限制上传表格类型
$file_type = $_FILES['myfile']['type'];
//application/vnd.ms-excel 为xls文件类型
//application/vnd.openxmlformats-officedocument.spreadsheetml.sheet 为xlsx文件类型
$type = 0;
if ($file_type == 'application/vnd.ms-excel') {
$type = 1;

} else {

'date' => '上传失败，只能上传xls或xlsx格式的Excel文件'
);
echo json_encode($back);
// echo "<script>alert('上传失败，只能上传xls或xlsx格式的Excel文件!');history.go(-1)</script>";
exit();
}
$_FILES['myfile']['tmp_name'] = str_replace('\\\\', '\\', $_FILES['myfile']['tmp_name']);
// print_r($_FILES['myfile']);
//注意，“\\\\”实际字符串就是两个\，其他两个是用来表示转义的。
//判断表格是否上传成功
if (is_uploaded_file($_FILES['myfile']['tmp_name'])) {
require_once dirname(__FILE__) . '/../Classes/PHPExcel.php';
require_once dirname(__FILE__) . '/../Classes/PHPExcel/IOFactory.php';

require_once dirname(__FILE__) . '/../Classes/PHPExcel/Reader/Excel5.php';
} elseif ($type == 2) {
require_once dirname(__FILE__) . '/../Classes/PHPExcel/Reader/Excel2007.php';
}
//以上三步加载phpExcel的类
if ($type == 1) {
$objReader = PHPExcel_IOFactory::createReader('Excel5');//use excel2007 for 2007 format
} elseif ($type == 2) {

}
//接收存在缓存中的excel表格
$filename = $_FILES['myfile']['tmp_name'];
$objPHPExcel = $objReader->load($filename); //$filename可以是上传的表格，或者是指定的表格
$sheet = $objPHPExcel->getSheet(0);
$highestRow = $sheet->getHighestRow(); // 取得总行数
// $highestColumn = $sheet->getHighestColumn(); // 取得总列数
//循环读取excel表格,读取一条,插入一条
//j表示从哪一行开始读取 从第二行开始读取，因为第一行是标题不保存
//$a表示列号
global $back;
if ($highestRow == 1) {
$back = array(
'message' => 'error',
'date' => '不能为空'
);
echo json_encode($back);
exit();
}
// 定义导入错误名称接受变量
$errorName = " ";
// 定义导入成功数量变量
$successNum = 0;
for ($j = 2; $j <= $highestRow; $j++) {
// 获取excel里面数据
//获取A(考核范围)列的值
$HAE_Name = preg_replace('# #', '', $objPHPExcel->getActiveSheet()->getCell("A" . $j)->getValue());

// 判断是否为空或者非法（
/*******************校验是否为空***************************/
if ($HAE_Name == null || $HAE_Name == '') {
$errorName .= '第' . $j . '考核范围不能为空';

// 插入数据库之前判断数据库是否存在该人员，如有则删除更新

insert_db1('HR_AssessUserLevel', $HR_AssessUserLevel);

// 封装返回结果
if ($successNum == 0) {

} else {

}
echo json_encode($back);
}
其中changeTo_XXX_ID（），delete_db1（），insert_db1（），为自己业务封装的方法
附：
(1) function insert_db1($table, $data, $replace = false)
{
global $mssql_connection;
if (!$mssql_connection) {
$mssql_connection = open_mssqlconn();
}
$keysql = $valsql = '';

if ($val == '') {
// echo 'aaa ';
$valsql .= empty($valsql) ? "null" : ", null";
} else {
// echo 'ccc ';
$valsql .= empty($valsql) ? "'$val'" : ", '$val'";
}
}
$method = $replace ? 'REPLACE' : 'INSERT';
$sql = "$method INTO $table ($keysql) VALUES ($valsql)";
$sql = stripslashes($sql); //去除特殊字符串前面的反斜杠
$sql = iconv("utf-8", "gbk", $sql); //PHP使用UTF-8编码。SQL Server 2008使用默认的GBK编码 在执行查询语句之前将查询语句及所要插入的数据转化为GBK编码。
// $sql="insert into $table (PMP_ID) values ('002')";
// echo $sql.'</br>';
// sqlsrv_query($mssql_connection,$sql);
$cursor = sqlsrv_query($mssql_connection, $sql);
return sqlsrv_rows_affected($cursor);
}
(2)
function delete_db1($table, $where)
{
global $mssql_connection;
if (!$mssql_connection) {
$mssql_connection = open_mssqlconn();
}
$wheresql = '';
foreach ($where as $key => $val) {
$wheresql .= empty($wheresql) ? " $key = '$val' " : " AND $key = '$val'";
}
$sql = "DELETE FROM $table WHERE $wheresql";
$cursor = sqlsrv_query($mssql_connection, $sql);
return sqlsrv_rows_affected($cursor);
}
(3) 数据库连接：
$mssql_connection = '';
function open_mssqlconn()
{
global $mssql_connection;
$MSSQL_SERVER = "xxxx";
$connectionInfo = array("Database" => "xxx", "UID" => "sa", "PWD" => "xxx");
if (!$mssql_connection) {
$mssql_link = sqlsrv_connect($MSSQL_SERVER, $connectionInfo);
if (!$mssql_link) {
echo "Could not connect.\n";
die(print_r(sqlsrv_errors(), true));
}
return $mssql_link;
} else {
return $mssql_connection;
}
}
