Title: Request by a specific custom fields Last modified: August 30, 2016 --- # Request by a specific custom fields * Resolved [rjme](https://wordpress.org/support/users/rjme/) * (@rjme) * [11 years ago](https://wordpress.org/support/topic/request-by-a-specific-custom-fields/) * I have a custom field (“special_field”) that either equals “1” or “0”. On all my other stuff I am using ?json=1&count=5 but I want to only get 5 posts that have “special_field” = “1”. What is the next thing that I should put on there? I can’t seem to find the answer myself. * [https://wordpress.org/plugins/json-api/](https://wordpress.org/plugins/json-api/) Viewing 6 replies - 1 through 6 (of 6 total) * [lucasabba](https://wordpress.org/support/users/lucasabba/) * (@lucasabba) * [10 years, 11 months ago](https://wordpress.org/support/topic/request-by-a-specific-custom-fields/#post-6223507) * I’ve the same problem, someone can help us? * [Goldenapps](https://wordpress.org/support/users/goldenapps/) * (@goldenapps) * [10 years, 11 months ago](https://wordpress.org/support/topic/request-by-a-specific-custom-fields/#post-6223556) * plz visit this page: * [https://wordpress.org/support/topic/plugin-json-api-add-meta-query-to-get_post?replies=2](https://wordpress.org/support/topic/plugin-json-api-add-meta-query-to-get_post?replies=2) * [cristophergv](https://wordpress.org/support/users/cristophergv/) * (@cristophergv) * [10 years, 9 months ago](https://wordpress.org/support/topic/request-by-a-specific-custom-fields/#post-6223569) * Hello rjme, * It is easy, when solicited query the system uses the parameters **meta_key** &** meta_value** as filters, namely: * If you created the custom field called special_field and its possible values ​​ 1 or 0 your query should look something like: * [http://www.mywebsite.com/?json=get_posts&post_type=post&](http://www.mywebsite.com/?json=get_posts&post_type=post&);** meta_key**=special_field&**meta_value**=1 or = 0 * according to whether you want to filter for **1 or 0.** * If you have other custom field called my_special_field with possible values ​​ yes or not your query would look like: * [http://www.mywebsite.com/?json=get_posts&post_type=post&](http://www.mywebsite.com/?json=get_posts&post_type=post&);** meta_key**=my_special_field&**meta_value**=yes * or * [http://www.mywebsite.com/?json=get_posts&post_type=post&](http://www.mywebsite.com/?json=get_posts&post_type=post&);** meta_key**=my_special_field&**meta_value**=no * Is everything, with that return values ​​can filter based on custom field. * Remember that you can use other parameters at WP_Query and seeing that functionality provides you. * [https://codex.wordpress.org/Class_Reference/WP_Query](https://codex.wordpress.org/Class_Reference/WP_Query) * Incidentally, the parameter post_type = post is optional, but it can be used in cases where for example you create a type of personalized post such artists, books, since that way you can get only results of such post as: * [http://www.mywebsite.com/?json=get_posts&post_type=](http://www.mywebsite.com/?json=get_posts&post_type=)** artista**&meta_key=**my_special_field**&meta_value=no * or * [http://www.mywebsite.com/?json=get_posts&post_type=](http://www.mywebsite.com/?json=get_posts&post_type=)** libro**&meta_key=**author**&meta_value=”**armando** “ * Anything you say, have made mobile applications using as wordpress backend and json plugin-api, so I have some experience. * P.S. Sorry for the bad English but I speak Spanish and use google translate 🙂 hehe * /**** **EN ESPAÑOL PARA MIS PAISANOS** *****/ Hola rjme, * Es facil, cuando solicited una consulta al sistema, usa los parametros meta_key& meta_value como filtros, es decir: * Si el campo personalizado que creaste se llama special_field y tiene como posibles valores 1 o 0 tu consulta deberia ser algo asi: * [http://www.mywebsite.com/?json=get_posts&post_type=post&meta_key=special_field&meta_value=1](http://www.mywebsite.com/?json=get_posts&post_type=post&meta_key=special_field&meta_value=1) or =0 * segun quieras filtrar ya sea por 1 o por 0. * Si tienes otro campo personalizado que se llama my_special_field con posible valores yes or not tu consulta quedaria asi: * [http://www.mywebsite.com/?json=get_posts&post_type=post&meta_key=my_special_field&meta_value=yes](http://www.mywebsite.com/?json=get_posts&post_type=post&meta_key=my_special_field&meta_value=yes) * or * [http://www.mywebsite.com/?json=get_posts&post_type=post&meta_key=my_special_field&meta_value=no](http://www.mywebsite.com/?json=get_posts&post_type=post&meta_key=my_special_field&meta_value=no) * Es todo, con eso puedes filtrar los valores devueltos basado en campo personalizado. * Recuerda que puedes usar otros parametros consultando WP_Query y viendo que funcionalidades te provee. * [https://codex.wordpress.org/Class_Reference/WP_Query](https://codex.wordpress.org/Class_Reference/WP_Query) * Por cierto, el parametro post_type=post es opcional, pero lo puedes usar en casos donde por ejemplo hayas creado un tipo de post personalizado por ejemplo Artistas, Libros, ya que de esa manera puedes obtener solo resultados de ese tipo de post por ejemplo: * [http://www.mywebsite.com/?json=get_posts&post_type=artista&meta_key=my_special_field&meta_value=no](http://www.mywebsite.com/?json=get_posts&post_type=artista&meta_key=my_special_field&meta_value=no) * or * [http://www.mywebsite.com/?json=get_posts&post_type=libro&meta_key=author&meta_value=”armando”](http://www.mywebsite.com/?json=get_posts&post_type=libro&meta_key=author&meta_value=”armando”); * Cualquier cosa me dices, he realizado aplicaciones moviles usando como backend wordpress y el plugin json-api, asi que tengo algo de experiencia. * P.D.
