Your zip file creation is having issue.
I would suggest you to first check you content availability and then create zip file and at last download it.
To create ZIP file
$sourcePath = 'uploads/sourceDirectory';
$targetPath = 'uploads/destDirectory';
if (file_exists($sourcePath)){
if(!copy($sourcePath, $targetPath)){ //Copy file source to destination directory
return ['status' => false, 'msg' => 'File missing'];
}
}
if (file_exists($targetPath)){ // check target directory
$this->zip->read_dir($targetPath,False); // read target directory
if(!$this->zip->archive($targetPath.'.zip')){ // zip target directory
return ['status' => false, 'msg' => 'Zip file creation Failed!'];
}else{
return ['status' => false, 'msg' => 'Zip file Created'];
}
}
