Question

我正在研究yii2框架。我正在使用pdf打印kartik\mpdf\Pdf文件。有一个名为subdivision的字段，我想在pdf文件的标题上打印。

$sql_r = "SELECT DISTINCT ogph.`id` AS 'OGP_Serial_No',DATE(ogph.`created_at`) AS 'Date',uu.`name` AS 'Created_By',ogpd.`meter_serial` AS 'Meter_Serial_Number',  u.`name` AS 'Issued_To', ps.`name` AS 'Store',sd.`name` AS 'Sub_Division',
IFNULL(ogph.`admin_incharge`,'') AS 'Admin_Incharge', IFNULL(ogph.`project_manager`,'') AS 'Project_Manager', IFNULL(ogph.`driver_name`,'') AS 'Driver_Name', IFNULL(ogpd.`remarks`,'') AS 'Remarks'  
FROM `ogp_header` ogph
INNER JOIN `ogp_detail` ogpd ON ogph.`id` = ogpd.`ogp_id` 
INNER JOIN `user` u ON ogph.`issuer` = u.`id`  
INNER JOIN `user` uu ON ogph.`created_by` = uu.`id`
INNER JOIN `survey_hesco_subdivision` sd ON ogph.`sub_division` = sd.`sub_div_code`
INNER JOIN `project_store` ps ON ogph.`store_id` = ps.`id` $where AND ogph.`id` = $ogp_id";
        $sql_r = $sql_r . " LIMIT " . $from . " OFFSET " . $to;

        $dataProvider = new SqlDataProvider([
            'sql' => $sql_r,
            'pagination' => false
        ]);


    $content = $this->renderPartial('view_pdf_ogp', ['dataProvider' => $dataProvider]);

    $pdf = new Pdf([
        // set to use core fonts only
        'mode' => Pdf::MODE_UTF8,
        // A4 papr format
        'format' => Pdf::FORMAT_A4,
        // portrait orientation
        'orientation' => Pdf::ORIENT_PORTRAIT,
        // stream to browser inline
        'destination' => Pdf::DEST_DOWNLOAD,
        // your html content input
        'content' => $content,
        // format content from your own css file if needed or use the
        // enhanced bootstrap css built by Krajee for mPDF formatting
        'cssFile' => '@vendor/kartik-v/yii2-mpdf/assets/kv-mpdf-bootstrap.min.css',
        // any css to be embedded if required
        'cssInline' => '.kv-heading-1{font-size:14px}',
        // set mPDF properties on the fly
        'options' => ['title' => 'OGP Document'],
        // call mPDF methods on the fly
        'methods' => [
            'SetHeader' => ['Name.||Generated On: ' . date("Y-m-d h:i:sa")],
            'SetFooter' => ['{PAGENO}']
        ]
    ]);

在上面的代码中，我想做一些像'SetHeader' => ['Accurate (PVT) LTD.|Sub-Division: Here I want to print the sub division name|Generated On: ' . date("Y-m-d h:i:sa")],

这样的事情

我尝试了什么？

我试图通过添加

来做到这一点

'SetHeader' => ['Name.|Sub-Division: '.<?php $model=$dataProvider->getModels()[0]; print_r($model['Sub_Division'])?>.'|Generated On: ' . date("Y-m-d h:i:sa")]

以及

'SetHeader' => ['Name.|Sub-Division: '.$content->Sub_Division.'|Generated On: ' . date("Y-m-d h:i:sa")],

但两人都给我non-object错误。是否有任何方法将字符串放在从查询中获取的标题上？

任何帮助都将受到高度赞赏。

Answer 1

'SetHeader' => ['Accurate (PVT) LTD.|Sub-Division: '.<?php $model=$dataProvider->getModels()[0]; print_r($model['Sub_Division'])?>.'|Generated On: ' . date("Y-m-d h:i:sa")]

你想用上面几行代码实现什么，你正在设置一个数组索引SetHeader，它希望它的值是一个字符串，为什么是php标签，为什么print_r当你需要时连接多个字符串。阅读如下。

'SetHeader' => ['header string goes here']

话虽这么说，你可以通过两种方法设置标题。

方法1

在配置数组中提供标头（这就是您正在尝试的方法），但您没有以正确的方式构建标头字符串。应该如下。

'SetHeader' => ['Accurate (PVT) LTD.|Sub-Division: '.$dataProvider->getModels()[0]['Sub_Division'].'|Generated On: ' . date("Y-m-d h:i:sa")]

以上配置意味着＆＃34;使用提供的参数＆＃34;调用SetHeader类的mPDF方法。

方法2

或者，您可以获取mPDF个对象并直接调用其SetHeader方法。

$mpdf = $pdf->api; // fetches mpdf api
$mpdf->SetHeader('Accurate (PVT) LTD.|Sub-Division: '.$dataProvider->getModels()[0]['Sub_Division'].'|Generated On: ' . date("Y-m-d h:i:sa"));
