Remove Meta Description in Joomla 1.5 Without Changing Core
Does anybody know how can I remove the meta tag description without changing Joomla core. I found that addingup $this->setDescription(null); in my template it would work but this just leave the tag empty. I'd like to take this off at all.
I have spent the whol开发者_StackOverflowe afternoon researching but it seems like changing core is the only option, however I'm not comfortable with this option since a future upgrade may overwrite my changes.
Thanks in advance!
in templates/mytemplate/ component.php /index.php remove the following :
<jdoc:include type="head" />
this will remove all elements
however it will also remove all js & css files which is not cool! so what i would do is this:
to access all the head elements as an array: $document = $this->getHeadData();
to access path ref: $baseURL=JURI::base(true);
to grab all scripts (inc all loaded with addScript()method) :
foreach ($document[scripts] as $key=>$value){
if (stristr($key,$baseURL)==NULL){$url= $baseURL."/".$key ;}else{$url=$key;}
$scripts .= "<script type=".$value." src=".$url."></script>";
};
to grab all stylesheets (inc all loaded with addStyleSheet()method):
foreach ($document[styleSheets] as $key=>$value){
if (stristr($key,$baseURL)==NULL){$url= $baseURL."/".$key ;}else{$url=$key;}
$style .= "<link rel='stylesheet' type=".$value[mime]." href=".$url." />";
};
to grab all internal script elements (e.g. added with addScriptDeclaration or JFactory::getEditor) use this with the script method:
foreach ($document[script] as $key=>$value){
$scripts .= "<script type=".$key." >".$value."</script>";
}
to grab all custom scripts (e.g. editor initialization params) :
foreach ($document[custom] as $value){
$custom .= $value;
}
finally echo the statements in the <head> :
<?
echo $style;
Echo $scripts;
echo $custom;
?>
Also the other way (without hacking the component.php) is to create a new tmpl file in the template folder i.e:
[path to install]/template/mytemplate/
in that folder there will be Index.php and component.php you can create another one e.g. blank.php and specify the headers you want here
with <jdoc:include type="component" />
call it with ?tmpl=blank
This can be done with a plugin. There isn't one that removes the tag entirely that I know of, however these is a plugin that removes the generator tag completely. You could easily modify this plugin to do the same for the description tag instead.
