Hi iamrobert! Thank you for decision.
So i went on my way.
I dont want use some plugins for it, i want do it only in php with core joomla.
I delete <jdoc:include type="head" />, and try create all with my scripts
I ask this question, because i dont know how made meta tags, hovever i think i know how it do (may be uncorrect, but it works

)
I decide this with core joomla addcustomTag
In index.php of my template i add in <head> this:
Code:
<?php foreach($this->_custom as $key => $value)
{
echo $value;
}
?>
And then in my flexicontent template item.php i add
Code:
$doc->addCustomTag( '<meta property="og:type" content="article" />');
$doc->addCustomTag( '<meta property="og:title" content="'.$item->title.'" />' );
$doc->addCustomTag( '<meta property="og:section" content="'.$somevariable.'" />' );
When rendering page - it looks like
Code:
<meta property="og:url" content="http://site.com/alias" />
<meta property="og:description" content="Post-graduate student of Moscow State University beat a female guard dorm homemade spear." />
<meta property="og:type" content="article" />
<meta property="og:title" content="Post-graduate student of Moscow State University was attacked with a homemade spear at the female guard" />
<meta property="og:section" content="Education" />
<meta property="og:image" content="http://site.com/images/stories/flexicontent/item_17_field_21/m_j0403195.jpg" />
<meta property="og:description"> - generate Flexi , but i dont know where
<meta property="og:section" > and <meta property="og:image"> - i take from custom field in template
It works with any tags, including css and scripts like
Code:
$doc->addCustomTag( '<script src="test.js" type="text/javascript"></script>' );
render as
Code:
<script src="/test.js" type="text/javascript"></script>
I think it very quite conveniently with Flexicontent - because i can use different scripts/styles/metas in different Flexi views
