gd - Coordinator : GD library already installed on server but show Your server does not support the GD function required to process this type of image

问题描述

I already installed GD library on server but if I upload image with jpg,png,jpeg image format then show error "Your server does not support the GD function required to process this type of image." If GD library is installed then why show these type of error ?

$config['upload_path'] = $this->upload_path;
$config['allowed_types'] = $this->image_types;
$config['max_size'] = $this->allowed_file_size;
$config['max_width'] = $this->Settings->iwidth;
$config['max_height'] = $this->Settings->iheight;
$config['overwrite'] = FALSE;
$config['encrypt_name'] = TRUE;
$config['max_filename'] = 25;                
$this->upload->initialize($config);

if (!$this->upload->do_upload('product_image')) {
    $error = $this->upload->display_errors();
    $this->session->set_flashdata('error', $error);

   redirect("products/edit/" . $id);
}

$photo = $this->upload->file_name;
$data['image'] = $photo;
$this->load->library('image_lib');
$config['image_library'] = 'gd2';
$config['source_image'] = $this->upload_path . $photo;
$config['new_image'] = $this->thumbs_path . $photo;
$config['maintain_ratio'] = TRUE;
$config['width'] = $this->Settings->twidth;
$config['height'] = $this->Settings->theight;

$this->image_lib->clear();
$this->image_lib->initialize($config);
if (!$this->image_lib->resize()) {
   echo $this->image_lib->display_errors();
}

解决方案

您正在传递$this->upload->file_name未知值。GD库找不到您传递给$photo验证的字符串/对象的图像格式和扩展名。

您应该使用$this->upload->data()来捕获上传的图像值，如下所示。

$config = [
    'upload_path' => $this->upload_path, // make sure you are adding tailing `/` in your upload path, else you should add `/` before joing the images below
    'allowed_types' => $this->image_types,
    'max_size' => $this->allowed_file_size,
    'max_width' => $this->Settings->iwidth,
    'max_height' => $this->Settings->iheight,
    'overwrite' => false,
    'encrypt_name' => true,
    'max_filename' => 25
];
$this->load->library('upload', $config);  // make sure you are loading the `upload` library, else it will load
$this->upload->initialize($config);             
if($this->upload->do_upload('product_image')){  
    $uploaded_data = $this->upload->data(); // here you should collect the uploaded data    
    $data['image'] = $uploaded_data['file_name'];   
    $config = [
        'image_library' => 'gd2',
        'source_image' => $this->upload_path . $uploaded_data['file_name'],
        'new_image' => $this->thumbs_path . $uploaded_data['file_name'],
        'maintain_ratio' => true,
        'width' => $this->Settings->twidth,
        'height' => $this->Settings->theight,
        'quality' => '100%',
    ];
    $this->load->library('image_lib', $config);
    $this->image_lib->initialize($config);
    if ($this->image_lib->resize()){
        return true;
    }else{
        return $this->image_lib->display_errors();
    }   
}else{
    $this->session->set_flashdata('error', $this->upload->display_errors());
    redirect("products/edit/" . $id);
}
