Re: Custom html helper

Re: Custom html helper
I'm not sure but I think you can provide an alias to the helper this way:
$helpers = array('CustomHtml' = 'Html');

Re: Custom html helper
Looks like you're right!
https://trac.cakephp.org/changeset/6453
Nate sneaked it in without mentioning it. I'm going to play around
with this now...

Re: custom html helper
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.

Hi all,
I want to have a custom HTML Helper in my helpers dir and it seems like
it's always the one belonging to the core that is used, it doesn't seem
to be the same with the form helper for instance.
any idea what i' doing wrong ?
is it an intended behaviour ?

RE: custom html helper
Extend the helper this way:
1. Create a file called myhtml.php on your app/views/helpers directory.
2. Have its contents be something like the following. I'm overriding method
selectTag as in your example, with some small changes, like... PLEASE USE
BRACES! :)
?php
loadHelper('html');
class MyhtmlHelper extends HtmlHelper
{
function selectTag($fieldName, $optionElements, $selected = null,
$selectAttr = array(), $optionAttr = null, $showEmpty = true, $return =
false)
{
if (!$selected)
{
$selected = parent::tagValue($fieldName);
}
return parent::setFormTag($fieldName, $optionElements,
$selected, $selectAttr, $optionAttr, $showEmpty, $return);
}
}
?
So you see whenever you need to call cake's html helper you just do
parent::method()
3. Then on your controllers add the helper:
var $helpers = array ( 'Myhtml' );
4. And use it on your views:
$myhtml-selectTag(...)

Re: custom html helper
thanks to both of you I really thought if I had a html.php in helpers folder it would be used instead of the core one like it seems to happen for form.php for instance ... if anyone is able to clarify ... :) tia thomas --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Cake PHP group.
