THEME_preprocess_image 和 THEME_image 之间的区别？

Question

Drupal 只能放入 template.php 这两个函数有什么区别？

function THEME_preprocess_image(&$variables) {
    // something
}

function THEME_image($variables) {
    // something
}

Answer 1

function theme_image 渲染可渲染数组的 HTML 输出。

THEME_preprocess_image

我相信，它的正确名称是 template_preprocess_HOOK，它在主题函数之前在 theme() 内部调用，例如。 THEME_image

请考虑这里的用例：

// In custom.module     
$variables = array( 
  'path' => 'path/to/img.jpg', 
  'alt' => 'Test alt',
  'title' => 'Test title',
  'width' => '50%',
  'height' => '50%',
  'attributes' => array('class' => 'some-img', 'id' => 'my-img'),
  );
$img = theme('image', $variables);

如果要更改图像的某些属性，请执行以下操作：

function mytheme_preprocess_image($vars) {
    // Do the changes, before it's rendered.
}
