Send email to create and attach PDF in CodeIgniter - codeigniter

Question

The output email gets sent but does not arrive i my email. I have added dompdf library. When I removed the code that creates the pdf then the mail was sent.
My code:
<?php
$this->load->library('dompdf_gen');
$this->dompdf->load_html($body);
$this->dompdf->render();
$output = $this->dompdf->output(APPPATH . 'Brochure.pdf', 'F');
$email = $this->input->post('email');
$subject = "some text";
$message = $body;
$this->sendEmail($email, $subject, $message);
$config = Array(
'mailtype' => 'html'
);
$this->load->library('email', $config);
$this->email->set_newline("\r\n");
$this->email->from('ul#ul.com');
$this->email->to($email);
$this->email->subject($subject);
$this->email->message($message);
$this->email->attach(APPPATH . 'Brochure.pdf');
if ($this->email->send())
{
echo 'Email send.';
}
else
{
show_error($this->email->print_debugger());
}

Answer 1

You must be save attachment as a file, so use file_put_contents to save pdf to a file. Set permission to 777 to accessible by public:
$this->load->library('dompdf_gen');
$this->dompdf->load_html($body);
$this->dompdf->render();
$output = $dompdf->output();
file_put_contents(APPPATH.'Brochure.pdf', $output);
chmod(APPPATH.'Brochure.pdf', 777);
$email=$this->input->post('email');
$subject="some text";
$message=$body;
$this->sendEmail($email,$subject,$message);
$config = Array(
'mailtype' => 'html' );
$this->load->library('email', $config);
$this->email->set_newline("\r\n");
$this->email->from('ul#ul.com');
$this->email->to($email);
$this->email->subject($subject);
$this->email->message($message);
$this->email->attach(APPPATH.'Brochure.pdf');
if($this->email->send())
{
echo 'Email send.';
}
else
{
show_error($this->email->print_debugger());
}

Use this library to convert html to pdf which I have modified for CI3.
https://github.com/shyamshingadiya/HTML2PDF-CI3
Please check below mentioned solution
//Load the library
$this->load->library('html2pdf');
//Set folder to save PDF to
$this->html2pdf->folder('./uploads/pdfs/');
//Set the filename to save/download as
$this->html2pdf->filename('new.pdf');
//Set the paper defaults
$this->html2pdf->paper('a4', 'portrait');
for Sending this particular file in email.
$this->load->library('email');
$this->email->from('your#example.com', 'Your Name');
$this->email->to('someone#example.com');
$this->email->subject('Email PDF Test');
$this->email->message('Testing the email a freshly created PDF');
$this->email->attach($path_to_pdf_file);
$this->email->send();
Let me know if it not work.
