CakePHP: image inside link, want to make link point to image location

问题

I have some images inside links that I want to essentially look like this:

<a href="/path/to/img.png"><img src="/path/to/img.png" /></a>

Clicking on the link should load the image it contains. I'm trying to use CakePHP's HTML helper to do this, as follows:

<?php
  echo $html->link(
    $html->image('img.png'),
    'img.png',
    array('escape' => false)
  );
?>

When I do this, however, I get the following code:

<a href="/pages/img.png"><img src="/path/to/img.png" /></a>

Without using absolute URLs, can I make the link's href attribute point to the image's correct location?

Thanks!

回答1:

This should do the trick:

echo $html->image('image.png', array('url' => '/' . IMAGES_URL . 'image.png'));

回答2:

you can also do this in 1.2

echo $html->link(
    $html->image('img.png'),
    'img.png',
    array(),
    null, 
    false
  );

or in 1.3

echo $html->link(
    $html->image('img.png'),
    'img.png',
    array(),
    array( 'escape' => false ),     
  );
