Hi Thomas,
I don't know in what order dirs are looked up for helpers, but after
what you said, I would assume the helpers directory from the core is
looked at first. However I ran into the same problem, the html helper
had a few things I wanted to improve and so what I did is creating my
own html helper;
I still didn't figure out how to 'extend' a helper... but I hope this
will help;
First I created a file called eo_html.php in my application helpers
dir. it looks like this; (partial)
<code>
<?php
class eoHtmlHelper extends Helper {
var $helpers = array('Html');
}
?>
</code>
the var $helpers = array('Html'); line ensures I'll be able to call the
html helper when needed.
Then I whenever I run into something in the html helper that makes no
sense in my app, I 'override' (sort of). For instance the
html->selectTag will not select the default value (from the object)
unless $selected is specified... so instead of modifying the
htmlhelper, I added the following to my helper;
<code>
function selectTag($fieldName, $optionElements, $selected = null,
$selectAttr = array(), $optionAttr = null, $showEmpty = true, $return =
false) {
if (!$selected) $selected = $this->Html->tagValue($fieldName);
return $this->Html->setFormTag($fieldName, $optionElements,
$selected, $selectAttr, $optionAttr, $showEmpty, $return);
}
</code>
notice how I call the original html helper with '$this->Html->...'
Finally, in my view, instead of going $html->selectTag, I use
$eoHtml->selectTag, of course after I added eoHtml to my $helpers array
in my controller!
I cannot say that's the best solution ever (and would appreciate any
comment in re to that!), but so far it's worked quite well!
Hope this helps!
Seb.
