我正在尝试循环通过照片数组并调整每张照片的大小两次。一次是拇指,一次是全尺寸图像。在第一个循环中一切都很好,但是在第二个、第三个、第四个循环中从来没有创建缩略图版本。我不知道我做错了什么。有人能从下面的代码看到我的错误吗?
$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();
}
试着把你的clear()
s放在resize()
之后,像这样:
这是我当前的结构:
|--- assets
| |--- images
| | |--- changed
| | |--- test.png
| | |--- test2.jpg
在我运行下面的代码之后,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();
}
