我试图将我的模型中的一些数据导出到带有“Laravel excel”的excel scheet,我已经完成了,但是我的结果远离我真正需要的内容
这就是我在下载文件中获得的内容:
这就是我真正想要实现的目标:
我的控制器部分:
//casting export...
Excel::create('ExcelExport', function($excel) use($filters, $agents) {
$main_arr = array();
foreach($agents as $value){
$main_arr[] = Card::cardForUser($value, $filters)->toArray();
}
$excel->sheet('Sheetshit', function($sheet) use($main_arr) {
//You may ask me "why are you using foreach?"
// and my answer will be:"I don`t KNOW, because it WORKS!"
foreach($main_arr as $one){
$sheet->fromArray($one);
}
});
})->export('xls');
模型部分:
public static function cardForUser($user_id, $filters = array()){
$query = static::UserId($user_id);//just gets 'where user id'
foreach($filters['fields'] as $select){
$query->addSelect($select);
}
return $query->get();
}
public function scopeUserId($query, $user_id) {
return $query->where('user_id', '=', $user_id);
}
$filters
数组由来自DB的字段名称组成,因此它基本上决定了哪些列包含在导出中。这意味着我的$main_arr
可能有1到5的内部字段长度。每个代理可以在DB中有很多行,或者根本没有行
设置了4个过滤器的$ main_arr转储示例:

Sooo ...我的问题是:
更新将已发布的工作代码作为答案。

我不会回答你的所有问题,因为你需要自己查看文档。但是我会告诉你如何获得这样的效果:
我认为它不仅仅能解释你做错了什么
以上excel文件的代码如下:
Excel::create('ExcelExport', function ($excel) {
$excel->sheet('Sheetname', function ($sheet) {
// first row styling and writing content
$sheet->mergeCells('A1:W1');
$sheet->row(1, function ($row) {
$row->setFontFamily('Comic Sans MS');
$row->setFontSize(30);
});
$sheet->row(1, array('Some big header here'));
// second row styling and writing content
$sheet->row(2, function ($row) {
// call cell manipulation methods
$row->setFontFamily('Comic Sans MS');
$row->setFontSize(15);
$row->setFontWeight('bold');
});
$sheet->row(2, array('Something else here'));
// getting data to display - in my case only one record
$users = User::get()->toArray();
// setting column names for data - you can of course set it manually
$sheet->appendRow(array_keys($users[0])); // column names
// getting last row number (the one we already filled and setting it to bold
$sheet->row($sheet->getHighestRow(), function ($row) {
$row->setFontWeight('bold');
});
// putting users data as next rows
foreach ($users as $user) {
$sheet->appendRow($user);
}
});
})->export('xls');

如何设置主标题(示例img中的“标题内容”)?
查看文档,这很容易:
$sheet->prependRow(1, array(
'Example header'
))->cell('A1', function($cell) {
$cell->setFontWeight('bold');
$cell->setFontSize(18);
});
我可以将子数组的标题加粗(ts_make等)吗?怎么样?
计算哪些行必须加粗:
$count = 2;
foreach($main_arr as $one){
$sheet->fromArray($one, null, 'A2');
$sheet->row($count, function($row) {
$row->setFontWeight('bold');
});
$count += count( $one ) + 1;
}
如何为每个代理制作子标题(我计划使用子数组键来显示多个代理)?
以与上述类似的方式:)
答案 2 :(得分:0)
Excel::create('Filename', function($excel) use($filters, $agents) {
$excel->sheet('sheetname', function($sheet) use( $agents, $filters) {
// first row with header title
$sheet->mergeCells('A1:E1');//merge for title
$sheet->row(1, function ($row) {
$row->setFontSize(18);
});
$sheet->row(1, array('Header Stuff') );//add title
$sub_titles = array(/*content*/);//array for agents names
$count = 2;//pointer for rows with agents name
foreach($agents as $agent_id){
//get agent name.
$agent_name = Model::AgentById(Auth::user(), $agent_id);
$sheet->appendRow(array($agent_name));//add agent name
$sheet->mergeCells('A'.$count.':'.'E'.$count);//merge for agent name
$sheet->row($sheet->getHighestRow(), function ($row) {//get last row at the moment and style it
//$row->setFontWeight('bold');
$row->setFontSize(14);
});
$cards = CardModel::cardForUser($agent_id, $filters)->toArray();//get cards for agent
//if there is cards show them, else show nothing message
if(count($cards) > 0){
$sheet->appendRow($sub_titles);//add sub-titles of agents fields
$sheet->row($sheet->getHighestRow(), function ($row) {
$row->setFontWeight('bold');
});
foreach($cards as $card){//add all agent fields
$sheet->appendRow($card);
}
$count += count($cards) + 2;
}
else{
$sheet->appendRow(array('nothing to show')));//add nothing to show message
$sheet->row($sheet->getHighestRow(), function ($row) {
$row->setFontWeight('bold');
});
$count += 2;
}
}
});
})->export('xls');

我建议您创建一个包含所需样式的Excel文件,然后将数据附加到此模板文件,请按照以下示例操作:
public function export_xls($expense_id, $file_format_id){
$expense = Expense::find($expense_id);
$file_format = FileFormat::find($file_format_id);
$routes = DB::table('buy_orders')
->join('expenses','expenses.id','=','buy_orders.expense_id')
->join('users','expenses.user_id','=','users.id')
->select(
'buy_orders.code',
'buy_orders.cost_center',
'buy_orders.book_account',
'buy_orders.active',
'buy_orders.expenditure',
'buy_orders.inventory',
'buy_orders.quantity',
'buy_orders.price_unit',
'buy_orders.description',
'buy_orders.estimated_value',
'buy_orders.destination',
'buy_orders.delivery_date'
)
->where('buy_orders.expense_id','=',$expense_id)
->orderBy('buy_orders.created_at','desc')
->get();
$data = json_decode(json_encode((array) $routes), true);
Excel::load('/storage/app/template.xls', function($file) use($expense, $data){
$file->setActiveSheetIndex(0)->setCellValue('D8', $expense->user->name);
$file->setActiveSheetIndex(0)->setCellValue('L8', $expense->application_date);
$file->setActiveSheetIndex(0)->setCellValue('P8', $expense->code);
$file->setActiveSheetIndex(0)->setCellValue('D45', $expense->description);
$row = 13;
foreach($data as $key => $temp) {
$col = 1;
foreach(array_keys($temp) as $value) {
$file->getActiveSheet()->setCellValueByColumnAndRow($col, $row, $temp[$value]);
$col++;
}
$row++;
}
})->export('xls');
}
这个想法是make和array然后使用setCellValueByColumnAndRow方法附加
