Hoje vou ensiar a criar um plugin bem simples e util nas redes sociais.
Esse plugin insere em seus artigos as chamadas Tags Open Graph
Para isso vamos precisar criar 2 arquivos.
O primeiro será o xml, chamamos de jrmetatags.xml
o conteudo desse arquivo será:
<?xml version=”1.0″ encoding=”utf-8″?>
<extension version=”1.6″ type=”plugin” group=”system” method=”upgrade”>
<name>System – JR MetaTags</name>

<version>1.2.0</version>

</description>
<files>
<filename plugin=”jrmetatags”>jrmetatags.php</filename>
</files>
<config>
<fields name=”params” >
<fieldset name=”basic”>
<field name=”site_name” type=”text” default=”” label=”nome do site” description=”Nome do seu site .”></field>
<field name=”image” type=”text” default=”” label=”url da imagem” description=”url da imagem .”></field>
</fieldset>
</fields>
</config>
</extension>
lembre-se de copiar exatamente igual.
o segundo aquivo que será criado é o jrmetatags.php (Os nomes dos arquivos é importante manter os mesmos.)

depois de criado os arquivos, zip os mesmos com o nome de jrmetatags.zip e faça upload para seu site Joomla.
Após isso basta habilitá-lo no menu: plugins
se quiser faça o download do plugin aqui
até a próxima!
