The last param, false, tells Cake to not escape the "title" (your
image, in this case). But you need to pass an 'escape' option in
$htmlAttributes to keep them from being escaped, also.
echo $html->link(
$html->image('navigation/nlOn-curved.gif'),
'http://www.external.com',
array(
'onmousever'=>'changeImages("nav01",
"images/nlOn-curved.gif");return true;',
'escape' => false
),
null, false
);
HOWEVER, there seems to be a bug in HtmlHelper, which I've posted to Trac. [1]
I think the Cake devs are trying to move as many params as possible
into array options, so that they may easily be handed down the chain
of methods. In this case, the link() method checks for that false
param to see if the title requires escaping, but it also looks in
$htmlAttributes for an escape option. If it's there, the title is also
escaped.
The problem, though, is that the option is then unset before the array
is handed off to create the link attributes. The fix is to comment the
unset() line:
if (isset($htmlAttributes['escape'])) {
$escapeTitle = $htmlAttributes['escape'];
//unset($htmlAttributes['escape']);
}
I guess the reasoning was that the 'escape' option was no longer
needed. But that fails to recognise that this option already had a
purpose before it was drafted into service controlling the escaping of
the link text ($title).
