How to convert HTML page to PDF in YII framework - html

Question

this is my output I need to convert my HTML page to PDF format in YII framework.
I have tried HTML2PDF where it gives me this error.
[ERROR] It seems that HTML2PDF dependencies are not installed… you must install them with composer install
Then I have installed composer also. But the error is same.
Suggest me solution of this or give any new idea.
this is my view code..
<tr>
<?php echo "<td>".$record->inv_article."</td>" ?>
<?php echo "<td>".$record->inv_no."</td>" ?>
<?php echo "<td >".$record->inv_weight."</td>" ?>
<?php echo "<td >".$record->inv_amt."</td>" ?>
<?php echo "<td >".$record->inv_freight."</td>" ?>
<?php echo "<td >".$record->inv_bilticharges."</td>" ?>
<?php echo "<td >".$record->inv_bilticharges."</td>" ?>
<?php $i++; ?>
</tr>
Here is my controller in my project
public function actionGeneratePDF($id){
$mpdf1 = Yii::app()->ePdf->mpdf();
$myhtml=$this->renderPartial('lorryprint', array(
'model'=>$model,'invid'=>$id), true);
$mpdf1->WriteHTML($myhtml);
$file_name= $id.'.pdf';
ob_end_clean();
$mpdf1->Output($file_name,EYiiPdf::OUTPUT_TO_DOWNLOAD );
}

I have the same problem couple of months ago, I wanted to convert the html page into pdf in Yii Framework. It took me 3 days to find out how to use it properly. So there are two ways to generate PDF from html by using PHP classes below:
HTML2PDF
mPDF
I have used both but I will prefer you to use mPDF. it is much better than HTML2PDF. Here is method on How to use mPDF in Yii Framework.
First of all you need
YiiPDF - Small Yii extension, that wraps a few PHP libraries (mPDF and HTML2PDF so far) to convert HTML to PDF.
mPDF - is a PHP class to generate PDF files from HTML with Unicode/UTF-8 and CJK support.
I have used mPDF Version 5.7 Because you don't need a composer to install it.
So just download Yii PDF and mPDF from above links and extract them and then Rename the folders to yii-pdf and mpdf and place them into your project in protected\extensions.
Then open your protected/config/main.php and add the below code.
'components'=>array(
'ePdf' => array(
'class' => 'ext.yii-pdf.EYiiPdf',
'params' => array(
'mpdf' => array(
'librarySourcePath' => 'application.extensions.mpdf.*',
'constants' => array(
'_MPDF_TEMP_PATH' => Yii::getPathOfAlias('application.runtime'),
),
'class'=>'mpdf', // the literal class filename to be loaded from the vendors folder
/*'defaultParams' => array( // More info: http://mpdf1.com/manual/index.php?tid=184
'mode' => '', // This parameter specifies the mode of the new document.
'format' => 'A4', // format A4, A5, ...
'default_font_size' => 0, // Sets the default document font size in points (pt)
'default_font' => '', // Sets the default font-family for the new document.
'mgl' => 15, // margin_left. Sets the page margins for the new document.
'mgr' => 15, // margin_right
'mgt' => 16, // margin_top
'mgb' => 16, // margin_bottom
'mgh' => 9, // margin_header
'mgf' => 9, // margin_footer
'orientation' => 'P', // landscape or portrait orientation
)*/
)
),
),
Please note: In above code 'class' => 'ext.yii-pdf.EYiiPdf', means that you have a file called EYiiPdf in protected/extensions/yii-pdf/ and similarly that mPDF extension 'librarySourcePath' => 'application.extensions.mpdf.*', exists in protected/extensions/mpdf
Then you can create a function in your controller.
public function actionGeneratePDF($id){
$model = AsfiUsers::model()->findByPk($id);
$mpdf1 = Yii::app()->ePdf->mpdf();
$myhtml=$this->renderPartial('ProfileView', array(
'personal_info'=>$model), true);
$mpdf1->WriteHTML($myhtml);
$file_name= $id.'.pdf';
ob_end_clean();
$mpdf1->Output($file_name,EYiiPdf::OUTPUT_TO_DOWNLOAD );
}
So in my View in ProfileView I have added a button at the top of it.
<?php echo CHtml::link('PDF Version',array('AsfiUser/GeneratePDF','id'=>$this->id), array('class'=>'btn btn-info btn-sm')); ?>
After click on that button, It will download the PDF of that html page. My Profile View has tables too so Thats why I have used mPDF not Html2PDF. In html2pdf, It doesnot give much options to adjust tables margin etc. But in mpdf it is automatically adjust and will be a perfect PDF.
FOR HTML2PDF
In case if you want to use HTML2PDF, all the steps are same. Just download Old version of html2pdf, New version will have problem like dependencies are not installed. Just like you have them now.
All steps are same, just add this into your protected/config/main.php below the mPDF class in yii-pdf component array.
'HTML2PDF' => array(
'librarySourcePath' => 'application.extensions.html2pdf.*',
'classFile' => 'html2pdf.class.php', // For adding to Yii::$classMap
/*'defaultParams' => array( // More info: http://wiki.spipu.net/doku.php?id=html2pdf:en:v4:accueil
'orientation' => 'P', // landscape or portrait orientation
'format' => 'A4', // format A4, A5, ...
'language' => 'en', // language: fr, en, it ...
'unicode' => true, // TRUE means clustering the input text IS unicode (default = true)
'encoding' => 'UTF-8', // charset encoding; Default is UTF-8
'marges' => array(5, 5, 5, 8), // margins by default, in order (left, top, right, bottom)
)*/
)
and then your controller function will be same just replace the name with mPDF.
public function actionGeneratePDF($id){
$model = AsfiUsers::model()->findByPk($id);
$html2pdf= Yii::app()->ePdf->HTML2PDF();
$myhtml=$this->renderPartial('ProfileView', array(
'personal_info'=>$model), true);
$html2pdf->WriteHTML($myhtml);
$file_name= $id.'.pdf';
ob_end_clean();
$html2pdf->Output($file_name,EYiiPdf::OUTPUT_TO_DOWNLOAD );
}
and create the same button in view for it. I hope it will work for you. I have used the same and working perfectly.
UPDATED:
This code works, just try to check you haven't made any mistake and secondly add this below code at the top of your html view file.
<?php
ob_start(); //started buffering
?>
<?php echo CHtml::link('PDF Version',array('AsfiUser/GeneratePDF','id'=>$this->id), array('class'=>'btn btn-info btn-sm')); ?>
It will add the button on the page which u want to make PDF, when u click on the button, it will download the file while it will take few seconds to a minute depending on page size.

add this line to ur controller
$myhtml=preg_replace("/<\\/?a(\\s+.*?>|>)/", "", $myhtml);
So your controller will be like this
public function actionGeneratePDF($id){
$mpdf1 = Yii::app()->ePdf->mpdf();
$myhtml=$this->renderPartial('lorryprint', array(
'model'=>$model,'invid'=>$id), true);
$myhtml=preg_replace("/<\\/?a(\\s+.*?>|>)/", "", $myhtml);
$mpdf1->WriteHTML($myhtml);
$file_name= $id.'.pdf';
ob_end_clean();
$mpdf1->Output($file_name,EYiiPdf::OUTPUT_TO_DOWNLOAD );
}
OR
If the above controller part doesnot work then fix ur code.
Your this line says $model
$myhtml=$this->renderPartial('lorryprint', array(
'model'=>$model,'invid'=>$id), true);
and in ur view you are using $record instead of $model, Have u done it properly in ur loop. Is ur View file showing results or not?
If it is showing properly,then ur view file lorryprint should be like this. add <td> outside the php tag.
<?php
ob_start(); //started buffering
?>
<?php echo CHtml::link('PDF Version',array('AsfiUser/GeneratePDF','id'=>$this->id), array('class'=>'btn btn-info btn-sm')); ?>
//more code here
<td><?php echo $record->inv_article;?></td>
<td><?php echo $record->inv_no;?></td>
<td><?php echo $record->inv_weight;?></td>
<td><?php echo $record->inv_amt;?></td>
<td><?php echo $record->inv_freight;?></td>
<td><?php echo $record->inv_bilticharges;?></td>
<td><?php echo $record->inv_bilticharges;?></td>
<?php $i++; ?>
