Codeigniter Numéro de téléchargement d'image

Question

J'utilise la bibliothèque de téléchargement de codeigniter pour télécharger plusieurs images. Généralement, cela fonctionne très bien, mais dans certains cas, l'image ne télécharge pas.

Fonction:

function do_upload_img() 
    { 
     if(isset($_FILES['portfolioimg']['size']) != 0){ 
      $name_array = array(); 
      $files = $_FILES; 
      $cpt = count($_FILES['portfolioimg']['name']); 

      // $config['source_image'] = ''; //get original image 
      $config['wm_type'] = 'overlay'; 
      $config['wm_overlay_path'] = './assets/img/watermark.png'; 
      $config['quality'] = 50; 
      $config['wm_vrt_alignment'] = 'middle'; 
      $config['wm_hor_alignment'] = 'center'; 
      $this->load->library('image_lib', $config); 

      for($i=0; $i<=$cpt-1; $i++) 
      { 
       $_FILES['userfile']['name']= $files['portfolioimg']['name'][$i]; 
       $_FILES['userfile']['type']= $files['portfolioimg']['type'][$i]; 
       $_FILES['userfile']['tmp_name']= $files['portfolioimg']['tmp_name'][$i]; 
       $_FILES['userfile']['error']= $files['portfolioimg']['error'][$i]; 
       $_FILES['userfile']['size']= $files['portfolioimg']['size'][$i];  

       $imgnam = rand(10,1000000).time(); 
       $ext = pathinfo($files['portfolioimg']['name'][$i], PATHINFO_EXTENSION); 
       if($this->upload->initialize($this->set_upload_options($imgnam))){ 
         $data = $this->upload->do_upload(); 
         $config['source_image'] = './assets/portfolio_img/' . 'Rookie_'.$imgnam.'.'.$ext; 
         $this->image_lib->initialize($config); 
         $this->image_lib->watermark(); 
         $name_array[] = $this->upload->data('file_name'); 
         $this->create_thumbnail('./assets/portfolio_img/',$imgnam,$ext); 
       }else{ 
        $this->session->set_flashdata('falsemsg','Only jpg, jpeg, png files are allowed to be uploaded.'); 
       } 
      } 
      return $name_array; 
     }else{ 
      return false; 
     } 
    } 
    private function set_upload_options($imgnam) 
    { 
      //upload an image options 
     $config = array(); 
     $config['upload_path'] = './assets/portfolio_img/'; 
     $config['allowed_types'] = 'jpeg|jpg|png|JPEG|JPG|PNG'; 
     $config['max_size']  = '0'; 
     $config['overwrite']  = true; 
     $config['file_name']  = 'Rookie_'.$imgnam; 

     return $config; 
    } 

Ceci est la fonction que Im utiliser pour télécharger les images. Je n'ai aucune idée de pourquoi ça ne marche pas parfois. Alors s'il vous plaît aidez-moi à comprendre l'erreur dans mon code. Merci d'avance.

$b='portfolioimg'; 
    $fileName = $_FILES[$b]['name']; 
       $images = $fileName; 
       $cpt = count($files); 
       for($i=1; $i<=$cpt; $i++) 
       { 
        $_FILES[$b]['name']= $files[$b]['name'][$i]; 
        $_FILES[$b]['type']= $files[$b]['type'][$i]; 
        $_FILES[$b]['tmp_name']= $files[$b]['tmp_name'][$i]; 
        $_FILES[$b]['error']= $files[$b]['error'][$i]; 
        $_FILES[$b]['size']= $files[$b]['size'][$i]; 
        $uploadPath = './assets/portfolio_img/'; 
        $config['upload_path'] = $uploadPath; 
        $config['allowed_types'] = 'gif|jpg|png|ico'; 
        $this->load->library('upload', $config); 
        $this->upload->initialize($config); 

      if($this->upload->do_upload($b.$i)){ 
      $fileData = $this->upload->data(); 
      $uploadData[$i]['file_name'] = $fileData['file_name']; 
      $im[$i]=$uploadData[$i]['file_name']; 
      } 
      } 
     $tblValues = array(

     'image'=>$images, // change field name, 


    ); 
    $this->db->insert('table_name', $tblValues);

Controller:

if(isset($_POST['submit'])) 
     { 
      $config['upload_path']="./uploads/"; 
      $config['allowed_types']='jpg|jpeg|gif|png'; 
      $this->load->library('upload',$config); 
      if($this->upload->do_upload()) 
      { 
       echo "file upload success"; 
      } 
      else 
      { 
       echo "file upload failed"; 
      } 
     } 

Vue:

<form action="<?php echo base_url();?>controller/function" method="POST" enctype="multipart/form-data" > 
    Select File To Upload:<br /> 
    <input type="file" name="userfile" /> 
    <br /><br /> 
    <input type="submit" name="submit" value="Upload" class="btn btn-success" /> 
</form>
