Re: Help with linked image swap
Thanks for the explanation - looks like I jumped into waters deeper
than I first thought.
I did the first part, although where do I modify the 'isset' attribute
as you said above?

Re: Help with linked image swap
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).

Re: Help with linked image swap
Thanks for the update, I had tried something similar, although did not
succeed as quotes were converted to ".
Here is what I attempted:
link(
$html->image('navigation/nlOn-curved.gif'),
'http://www.external.com',
array(
'onmousever'=>'changeImages("nav01",
"images/nlOn-curved.gif");
return true;'
),
null, false) ?>
Although the above turned out to be:
http://www.external.com"; onmousever="changeImages
("nav01", "images/nlOn-curved.gif"); return
true;">
So I must be missing something here. Is there a way to force or escape
the quote to be literal as opposed to being converted?

Re: Help with linked image swap
use the html helper : http://book.cakephp.org/view/206/Inserting-Well-Formatted-elements image(string $path, array $htmlAttributes = array()) in your view (inside a php block) echo $html->image( "menu1.jpg", array( "onmouseover"=>"yourJsRollOverFunc()", "onclick"=>"jsFunc()", "class"=>"mycssclass" ) ); wrap the php block with your link... this should do the trick On Feb 6, 10:14 pm, Zolthar wrote: > Learning cake/programming for the first time so please excuse me if > this is a very noob question.
