Todo desarrollador de plantillas debe saber que los temas de WordPress se estructuran en posiciones, ganchos o hooks.<\/p>\n

En WordPress hay dos tipos de hooks: acciones y\/o filtros. En este art\u00edculo solamente vamos a hablar de las acciones, ya que son generalmente m\u00e1s simples, pero todas sus lecciones se pueden aplicar a los filtros sin mucha dificultad.<\/p>\n

Los ganchos o hooks<\/a> son funciones, un buen ejemplo es wp_head()<\/a>. Esta funci\u00f3n est\u00e1 definida en wp-includes\/general-template.php y las plantillas de WordPress lo utilizan principalmente para a\u00f1adir scripts y hojas de estilo en la cabecera.<\/p>\n

Su implementaci\u00f3n es muy sencilla:<\/p>\n

<\/a>Source code<\/a><\/td><\/a> <\/a> <\/a> <\/td><\/tr><\/table><\/div>
function<\/span> wp_head(<\/span>)<\/span> {<\/span>\n    do_action(<\/span>'wp_head'<\/span>)<\/span>;<\/span>\n}<\/span><\/pre><\/div><\/div>\n
 <\/p>\n
La funci\u00f3n do_action hace el trabajo duro, a\u00f1adiendo la funci\u00f3n wp_head en el sistema de ganchos de WordPress.<\/p>\n
Si quieres ir m\u00e1s all\u00e1, siempre puedes a\u00f1adir tus propios hooks para hacer m\u00e1s personalizable y flexible tu plantilla. Es incre\u00edblemente sencillo a\u00f1adir nuevos ganchos de la misma manera.<\/p>\n
En el ejemplo vamos a a\u00f1adir una nueva posici\u00f3n por encima del footer de nuestra p\u00e1gina.<\/p>\n
Hay tres pasos para a\u00f1adir un gancho a medida en un tema.<\/p>\n
En primer lugar, agrega la funci\u00f3n de enlace en el functions.php de tu plantilla:<\/p>\n
<\/a>Source code<\/a><\/td><\/a> <\/a> <\/a> <\/td><\/tr><\/table><\/div>
function<\/span> pre_footer(<\/span>)<\/span> {<\/span>\n    do_action(<\/span>'pre_footer'<\/span>)<\/span>;<\/span>\n}<\/span><\/pre><\/div><\/div>\n
 <\/p>\n
En segundo lugar, agrega la acci\u00f3n a tu tema en el lugar donde desea que se ejecute. En nuestro caso, agregaremos lo siguiente en el footer.php en el lugar que corresponda:<\/p>\n
<\/a>Source code<\/a><\/td><\/a> <\/a> <\/a> <\/td><\/tr><\/table><\/div>
<?php<\/span> pre_footer(<\/span>)<\/span>;<\/span> ?><\/span><\/pre><\/div><\/div>\n
 <\/p>\n
Finalmente podemos a\u00f1adir acciones a nuestro nuevo gancho de la siguiente forma en el functions.php:<\/p>\n
<\/a>Source code<\/a><\/td><\/a> <\/a> <\/a> <\/td><\/tr><\/table><\/div>
function<\/span> output_text(<\/span>)<\/span> {<\/span>\n    echo<\/span> '<p>Your text.<\/p>'<\/span>;<\/span>\n}<\/span>\n \nadd_action(<\/span>'pre_footer'<\/span>,<\/span>'output_text'<\/span>,<\/span> 5)<\/span>;<\/span><\/pre><\/div><\/div>\n
Ahora en el tema aparecer\u00e1 un p\u00e1rrafo con el texto \u00abYour text\u00bb antes del pie de p\u00e1gina.<\/p>\n","protected":false},"excerpt":{"rendered":"
