    force_download($name, $data); 
    delete_files($this->file_path . '/'.$name);` 

Answer 1

Ich werde ein Stück Code teilen, der Ihnen helfen kann. Al müssen Sie tun, um die Daten gemäß Ihrer Anforderung anzupassen. Bitte überprüfen Sie den Code unter

<?php 
    $this->db->select("a.lead_id,a.business_name,a.a.contact_name_first,a.contact_name_last,a.work_email,a.contact_email,a.work_number,a.cell_no,a.city,a.state,a.zip,a.date_added,IF(a.label_type <> 0,'Important',' ') as label, b.company_name"); 
    $this->db->from('leads a'); 
    $this->db->join('companies b', 'b.id = a.company'); 
    $this->db->join('lead_note c', 'c.lead_id = a.id'); 

    $query = $this->db->get(); 
    $result = $query->result_array(); 

    if($query->num_rows() > 0){ 
     $delimiter = ","; 
     $filename = "members_" . date('Y-m-d') . ".csv"; 

     //create a file pointer 
     $f = fopen('php://memory', 'w'); 

     //set column headers 
     $fields = array('Lead ID','Business','First Name','Last Name','Email','Personal Email','Work Number','Cell No','City','State','Zip','Date Added'); 

     //output each row of the data, format line as csv and write to file pointer 
     foreach($result as $row){ 

      $lineData = array($row['lead_id'], $row['contact_name_first'], $row['contact_name_last'], $row['work_email'], $row['contact_email'], $row['work_number'], $row['cell_no'], $row['city'], $row['state'], $row['zip'], $row['date_added'], $row['label'], $row['company_name']); 
      fputcsv($f, $lineData, $delimiter); 
     } 

     //move back to beginning of file 
     fseek($f, 0); 

     //set headers to download file rather than displayed 
     header('Content-Type: text/csv'); 
     header('Content-Disposition: attachment; filename="' . $filename . '";'); 

     //output all remaining data on a file pointer 
     fpassthru($f); 
    } 
    exit; 

    ?> 

Hoffen, dass dies hilft. Verwenden Sie keine Leerzeichen für Alias- und Tabellennamen. Wenn Sie Leerzeichen verwenden, müssen Sie die Häkchen korrekt verwenden. Ich empfehle Camelcase oder undersoce convension für Tabellen Benennung und Aliase

Vielen Dank für alle .. zu helfen, wie ich auf diese Weise tat ..

check_admin(); 
    header('Content-Type: text/csv; charset=utf-8'); 
    $name = 'leads-'.date('d-m-Y').'.csv'; 
    header('Content-Disposition: attachment; filename='.$name.''); 
    $output = fopen("php://output", "w"); 
    fputcsv($output, array('Lead ID', 'Business', 'First Name' ,'Last Name', 'Email','Work Number','Cell No','City','State','Zip','Date Added', 'Label','company name','Business', 'First Name' ,'Last Name', 'Email','Work Number','Cell No')); 
    $query = "SELECT leads.`lead_id`, leads.`business_name` as `Business`, leads.`contact_name` as `First Name`, leads.`contact_name_last` as `Last Name`, leads.`work_email` as `Email`, leads.`work_number` as `Work Number`, leads.`cell_no` as `Cell No`, `city` as `City`, `state` as `State`, `zip` as `Zip`, `date_added` as `Date Added`, IF(label_type <> 0, 'Important', ' ') as Label, `companies`.`company_name` as `company name`,lead_contact.`company_name` as `Business1`, lead_contact.`contact_name` as `First Name1`, lead_contact.`contact_name_last` as `Last Name1`, lead_contact.`work_email` as `Email1`, lead_contact.`work_number` as `Work Number1`, lead_contact.`cell_no` as `Cell No1` FROM `leads` Left JOIN `companies` ON `companies`.`id` = `leads`.`company` Left JOIN `lead_contact` ON `lead_contact`.`lead_id` = `leads`.`lead_id`"; 
    $all_leads = $this->db->query($query); 
    foreach ($all_leads->result_array() as $lead){ 
     $lead_id = $lead['lead_id']; 
     $query = "SELECT `note_date`,`notes` from lead_notes where lead_id='$lead_id'"; 
     $leads_notes = $this->db->query($query); 
     fputcsv($output, $lead); 
     //fputcsv($output, array('','Lead ID', 'Added', 'Notes')); 
    foreach ($leads_notes->result_array() as $leads_note){ 

     fputcsv($output, $leads_note); 

    } 

}
