Codeiginter多个图像调整大小不按预期工作

Question

我试图通过照片数组循环，并调整每个照片两次。一次用于拇指，然后用于全尺寸图像。在第一个循环中一切正常，但第二，第三，第四等没有创建缩略图版本。我无法弄清楚我做错了什么。任何人都可以从下面的代码中看到我的错误？

$this->load->library('image_lib'); 
foreach($photos as $current => $photo) {     

    // Create Thumb 
    $thumb_config = array(); 
    $thumb_config['create_thumb'] = TRUE; 
    $thumb_config['image_library'] = 'gd2'; 
    $thumb_config['source_image'] = $photo['full_path']; 
    $thumb_config['maintain_ratio'] = TRUE; 
    $thumb_config['width'] = 550; 
    $thumb_config['height'] = 550; 

    $this->image_lib->clear(); 
    $this->image_lib->initialize($thumb_config); 
    $this->image_lib->resize(); 
    // Resize Photo 
    $resize_config = array(); 
    $resize_config['create_thumb'] = FALSE; 
    $resize_config['image_library'] = 'gd2'; 
    $resize_config['source_image'] = $photo['full_path']; 
    $resize_config['maintain_ratio'] = TRUE; 
    $resize_config['width'] = 1500; 
    $resize_config['height'] = 1500; 

    $this->image_lib->clear(); 
    $this->image_lib->initialize($resize_config); 
    $this->image_lib->resize(); 
}

尝试resize()这样以后把你的clear() S：

这是我目前的结构：

|--- assets 
| |--- images 
| | |--- changed 
| | |--- test.png 
| | |--- test2.jpg 

后，我运行下面的代码，我有：

|--- assets 
| |--- images 
| | |--- changed 
| | | |--- test.png 
| | | |--- test2.jpg 
| | | |--- test_thumb.png 
| | | |--- test2_thumb.jpg 
| | |--- test.png 
| | |--- test2.jpg 

这是我使用的代码：

$this->load->library('image_lib'); 

    $photos = array(
     array(
      "full_path" => "assets/images/", 
      "name" => "test.png" 
     ), 
     array(
      "full_path" => "assets/images/", 
      "name" => "test2.jpg" 
     ), 
    ); 
    foreach ($photos as $current => $photo) { 
     // Create Thumb 
     $thumb_config = array(); 
     $thumb_config['create_thumb'] = TRUE; 
     $thumb_config['image_library'] = 'gd2'; 
     $thumb_config['source_image'] = $photo['full_path'] . $photo['name']; 
     $thumb_config['new_image'] = $photo['full_path'] . "changed/" . $photo['name']; 
     $thumb_config['maintain_ratio'] = TRUE; 
     $thumb_config['width'] = 550; 
     $thumb_config['height'] = 550; 

     $this->image_lib->initialize($thumb_config); 

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

     // Resize Photo 
     $resize_config = array(); 
     $resize_config['create_thumb'] = FALSE; 
     $resize_config['image_library'] = 'gd2'; 
     $resize_config['source_image'] = $photo['full_path'] . $photo['name']; 
     $resize_config['new_image'] = $photo['full_path'] . "changed/" . $photo['name']; 
     $resize_config['maintain_ratio'] = TRUE; 
     $resize_config['width'] = 1500; 
     $resize_config['height'] = 1500; 

     $this->image_lib->initialize($resize_config); 

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