在magento中的不同phtml文件中访问变量

Question

i want to defer javascript files form magneto head.phtml file, the scripts and css are called by the $this->getCssJsHtml(); function in magneto head.phtml file so is just simple substr the output like

$str  =  $this->getCssJsHtml();
$css  =  substr($str, 0, strpos($str, "<script"));
$js   =  substr($str,strpos($str, "<script") );

then i save the $js to registry like

Mage::register('hs_scripts'  ,  $js); 

and in the footer.phtml i call it from the registry like

echo Mage::registry("hs_scripts");

now every thing work well unless i enable the magneto cache , and when i enable the magneto cache and then open let say homepage then, on every next page only the homepage scripts get loaded,

if i disable the cache, everything work, so i need a way to store data form 1 phtml file and then access it on other file

Answer 1

Instead adding your scripts to footer block, which gets cached, try creating new block and adding it to before_body_end block.

[theme]/layout/local.xml file:

<default>
    <reference name="before_body_end">
        <block type="core/template" name="footer.scripts" template="page/html/footer/scripts.phtml"/>
    </reference>
</default>

[theme]/template/page/html/footer/scripts.phtml file:

echo Mage::registry('hs_scripts');

Best of luck!
