Dompdf library multiple saperate files save not working
问题
你好，我理解你的要求，以下是你提供的代码的翻译部分：
public function export_information(){
$this->load->library('pdf');
$export_info_sql = "SELECT * FROM offences_issued";
$export_info_query = $this->db->query($export_info_sql);
$export_info_result = $export_info_query->result();
$query_html = "";
$counter = 1;
foreach ($export_info_result as $offence) {
$directory_path = FCPATH."offences/".$counter.".pdf";
$query_html .= "<table width=100% border=1>";
$query_html .= "<tr><th>Offence ID</th></tr>";
$query_html .= "<tr><td>".$offence->issued_id."</td></tr>";
$query_html .= "</table>";
$this->pdf->loadHtml($query_html);
$this->pdf->setPaper('A4', 'portrait');
$this->pdf->render();
$output = $this->pdf->output();
if (!file_exists($directory_path)) {
file_put_contents($directory_path, $output);
}
$counter++;
}
}
希望这有助于你解决问题。如果你有其他问题，可以随时提出。

Hello everyone I am facing a problem with dompdf in Codeigniter when I am trying to save multiple pdf files in a loop. It saves only one file but I need multiple files to save in the folder separately for each user.
I tried this
public function export_information(){
$this->load->library('pdf');
$export_info_sql = "SELECT * FROM offences_issued";
$export_info_query = $this->db->query($export_info_sql);
$export_info_result = $export_info_query->result();
$query_html = "";
$counter = 1;
foreach ($export_info_result as $offence) {
$directory_path = FCPATH."offences/".$counter.".pdf";
$query_html .= "<table width=100% border=1>";
$query_html .= "<tr><th>Offence ID</th></tr>";
$query_html .= "<tr><td>".$offence->issued_id."</td></tr>";
$query_html .= "</table>";
$this->pdf->loadHtml($query_html);
$this->pdf->setPaper('A4', 'portrait');
$this->pdf->render();
$output = $this->pdf->output();
if (!file_exists($directory_path)) {
file_put_contents($directory_path, $output);
}
$counter++;
}
// echo $query_html;
// exit;
}
It shows this error
