Mehrere Bilder in Array hochladen Codeigniter

Question

Guten Abend Leute, ich habe ein Problem in meinem Code. Ich mache ein Galerieformular mit separaten Feldern.

Ich habe immer eine "none" -Ausgabe, weil es meine Eingaben nicht erhält, obwohl ich etwas in das Feld thumbnails [] eingegeben habe.

Jeder hat eine Idee, wie ich es beheben kann und wie es gemacht werden kann. Vielen Dank.

Hier ist mein Code in html:

Main Image: 
<input type="file" name="file1" required/> 
Thumbnails: 
<input type="file" name="thumbnails[]" /> 
<input type="file" name="thumbnails[]" /> 
<input type="file" name="thumbnails[]" /> 

In meinem Controller:

$config = array(
    'upload_path' => "./uploads/workplace/", 
    'allowed_types' => "jpg|png|jpeg", 
    'remove_spaces' => TRUE, 
    'max_size' => "2048000", // Can be set to particular file size , here it is 2 MB(2048 Kb) 
    'max_height' => "0", 
    'max_width' => "0" 
    ); 
    $this->load->library('upload', $config); 
    if($this->upload->do_upload('file1')) 
    { 
     $config = array(
     'upload_path' => "./uploads/workplace/", 
     'allowed_types' => "jpg|png|jpeg", 
     'remove_spaces' => TRUE, 
     'max_size' => "2048000", // Can be set to particular file size , here it is 2 MB(2048 Kb) 
     'max_height' => "0", 
     'max_width' => "0" 
    ); 
     $this->load->library('upload', $config);    
     if($this->upload->do_upload('thumbnails[]')) 
     { 
     echo "yea"; 
     } 
     else 
     { 
     echo "none"; 
     } 
    } 

Answer 1

Wie es in related answer geschrieben worden ist, wird die Upload-Bibliothek nicht Hochladen mehrerer Dateien verwalten, aber Sie kann das gesamte $ _FILES-Array mit dem Namen des Arrays durchlaufen und für jedes einzelne Thumbnail hochladen.

Sie foreach $ _FILES mit etwas wie folgt aus:

foreach ($_FILES as $key => $value) { 
    $this->upload->initialize($config); 
    if (!$this->upload->do_upload($key)) { 
     //here be errors 
    } 
}

$config = array(
'upload_path' => "./uploads/workplace/", 
'allowed_types' => "jpg|png|jpeg", 
'remove_spaces' => TRUE, 
'max_size' => "2048000", // Can be set to particular file size , here it is     2 MB(2048 Kb) 
'max_height' => "0", 
'max_width' => "0" 
); 
$this->load->library('upload', $config); 

foreach ($_FILES as $key) { 

     if (!$this->upload->do_upload($key)) { 
      echo $this->image_lib->display_errors(); 
     }else 
     { 
      echo "<strong>Your Thumb image has been successfully Uploded..!!</strong><br><br>"; 
     } 
    }
