WP_Query con "post_title LIKE 'something%'"?

Necesito hacer un WP_Query con un LIKEen el post_title.

Empecé coneste WP_Querynormal:

 $wp_query = new WP_Query( 
    array (
        'post_type'        => 'wp_exposants',
        'posts_per_page'   => '1',
        'post_status'      => 'publish',
        'orderby'          => 'title', 
        'order'            => 'ASC',
        'paged'            => $paged
    )
);

Pero lo que realmente quiero hacer se ve asíen SQL:

 $query = "
        SELECT      *
        FROM        $wpdb->posts
        WHERE       $wpdb->posts.post_title LIKE '$param2%'
        AND         $wpdb->posts.post_type = 'wp_exposants'
        ORDER BY    $wpdb->posts.post_title
";
$wpdb->get_results($query);

La salidaimprime los resultados queespero,pero utilizoel <?php while ( $wp_query->have_posts() ) : $wp_query->the_post(); ?>paramostrar los resultados.
Yesonofunciona con $wpdb->get_results().

¿Cómopuedo lograr lo que describí aquí?

I need to do a WP_Query with a LIKE on the post_title.

I started with this regular WP_Query:

$wp_query = new WP_Query( 
    array (
        'post_type'        => 'wp_exposants',
        'posts_per_page'   => '1',
        'post_status'      => 'publish',
        'orderby'          => 'title', 
        'order'            => 'ASC',
        'paged'            => $paged
    )
);

But what I actually want to do looks like this in SQL:

$query = "
        SELECT      *
        FROM        $wpdb->posts
        WHERE       $wpdb->posts.post_title LIKE '$param2%'
        AND         $wpdb->posts.post_type = 'wp_exposants'
        ORDER BY    $wpdb->posts.post_title
";
$wpdb->get_results($query);

The output prints the results i'm excpecting, but I use the regular <?php while ( $wp_query->have_posts() ) : $wp_query->the_post(); ?> to display the results.
And that is not working with $wpdb->get_results().

How can I achieve what I described here?

Simplificado:

 function title_filter( $where, &$wp_query )
{
    global $wpdb;
    // 2. pull the custom query in here:
    if ( $search_term = $wp_query->get( 'search_prod_title' ) ) {
        $where .= ' AND ' . $wpdb->posts . '.post_title LIKE \'%' . esc_sql( like_escape( $search_term ) ) . '%\'';
    }
    return $where;
}

$args = array(
    'post_type' => 'product',
    'posts_per_page' => $page_size,
    'paged' => $page,
    // 1. define a custom query var here to pass your term through:
    'search_prod_title' => $search_term,
    'post_status' => 'publish',
    'orderby'     => 'title', 
    'order'       => 'ASC'
);

add_filter( 'posts_where', 'title_filter', 10, 2 );
$wp_query = new WP_Query($args);
remove_filter( 'posts_where', 'title_filter', 10 );
return $wp_query;

Simplified:

function title_filter( $where, &$wp_query )
{
    global $wpdb;
    // 2. pull the custom query in here:
    if ( $search_term = $wp_query->get( 'search_prod_title' ) ) {
        $where .= ' AND ' . $wpdb->posts . '.post_title LIKE \'%' . esc_sql( like_escape( $search_term ) ) . '%\'';
    }
    return $where;
}

$args = array(
    'post_type' => 'product',
    'posts_per_page' => $page_size,
    'paged' => $page,
    // 1. define a custom query var here to pass your term through:
    'search_prod_title' => $search_term,
    'post_status' => 'publish',
    'orderby'     => 'title', 
    'order'       => 'ASC'
);

add_filter( 'posts_where', 'title_filter', 10, 2 );
$wp_query = new WP_Query($args);
remove_filter( 'posts_where', 'title_filter', 10 );
return $wp_query;

Utilice '$ wpdb->esc_like ('en lugar de 'esc_sql (like_escape ('

Use '$wpdb->esc_like (' instead of 'esc_sql( like_escape('

@fdrv Tiene razón,pero según wp docs $ wpdb->esc_liketodavíanecesitaesc_sql ().Entonces creo queel código correcto seríaesc_sql ($ wpdb->esc_like ($ search_term))

@fdrv You are right but according to wp docs $wpdb->esc_like still need esc_sql(). So I think the correct code would be esc_sql( $wpdb->esc_like( $search_term ) )

Quería actualizareste códigoen el quetrabajaronpara wordpress 4.0 y superior,ya queesc_sql ()está obsoletoen 4.0 superior.

function title_filter($where, &$wp_query){ global $wpdb; if($search_term = $wp_query->get( 'search_prod_title' )){ /*using the esc_like() in here instead of other esc_sql()*/ $search_term = $wpdb->esc_like($search_term); $search_term = ' \'%' . $search_term . '%\''; $where .= ' AND ' . $wpdb->posts . '.post_title LIKE '.$search_term; } return $where; }

El resto delmaterialeselmismo.

También quiero señalar quepuede usar la variable s dentro de los argumentos de WP_Queryparapasartérminos debúsqueda,quetambiénbuscaráneltítulo de lapublicación,creo.

Así:

$args = array( 'post_type' => 'post', 's' => $search_term, 'post_status' => 'publish', 'orderby' => 'title', 'order' => 'ASC' ); $wp_query = new WP_Query($args);
Wanted to update this code you guys worked on for the wordpress 4.0 and above as esc_sql() is deprecated in 4.0 higher.

function title_filter($where, &$wp_query){ global $wpdb; if($search_term = $wp_query->get( 'search_prod_title' )){ /*using the esc_like() in here instead of other esc_sql()*/ $search_term = $wpdb->esc_like($search_term); $search_term = ' \'%' . $search_term . '%\''; $where .= ' AND ' . $wpdb->posts . '.post_title LIKE '.$search_term; } return $where; }

Rest of the stuff is same.

Also I want to point out you can use s variable within WP_Query arguments to pass search terms, which will also search for post title i believe.

Like this:

$args = array( 'post_type' => 'post', 's' => $search_term, 'post_status' => 'publish', 'orderby' => 'title', 'order' => 'ASC' ); $wp_query = new WP_Query($args);

Con alguna solución vulnerablepublicada aquí,vengo con una versión unpoco simplificada y saneada.

Primero,creamos unafunciónparaelfiltro posts_where que lepermitemostrar solo laspublicaciones que cumplen condicionesespecíficas:

function cc_post_title_filter($where, &$wp_query) { global $wpdb; if ( $search_term = $wp_query->get( 'cc_search_post_title' ) ) { $where .= ' AND ' . $wpdb->posts . '.post_title LIKE \'%' . $wpdb->esc_like( $search_term ) . '%\''; } return $where; }

Ahora agregamos cc_search_post_titleen nuestros argumentos de consulta:

$args = array( 'cc_search_post_title' => $search_term, // search post title only 'post_status' => 'publish', );

Yfinalmenteenvuelvaelfiltro alrededor de la consulta:

add_filter( 'posts_where', 'cc_post_title_filter', 10, 2 ); $query = new WP_Query($args); remove_filter( 'posts_where', 'cc_post_title_filter', 10 );

Uso deget_posts ()

Ciertasfunciones que recuperanpublicacionesnoejecutanfiltros,por lo que lasfunciones defiltroposts_where que adjuntasnomodificarán la consulta. Siplanea usar get_posts()para consultar suspublicaciones,debeestablecer suppress_filtersen falsoen sumatriz de argumentos:

$args = array( 'cc_search_post_title' => $search_term, 'suppress_filters' => FALSE, 'post_status' => 'publish', );

Ahorapuede usar get_posts():

add_filter( 'posts_where', 'cc_post_title_filter', 10, 2 ); $posts = get_posts($args); remove_filter( 'posts_where', 'cc_post_title_filter', 10 );

¿Quépasa conelparámetro s?

Elparámetro sestá disponible:

$args = array( 's' => $search_term, );

Mientras agrega sutérmino debúsquedaen eltrabajo deparámetro s ybuscaráeltítulo de lapublicación,también buscaráel contenido de lapublicación.

¿Quépasa conelparámetro title que se agregó con WP 4.4?

Pasar untérmino debúsqueda alparámetro title:

$args = array( 'title' => $search_term, );

Es sensible amayúsculas yminúsculas y LIKE,no %LIKE%. Esto significa que labúsqueda de hellono devolverá lapublicación coneltítulo Hello World o Hello.
With some vulnerable solution posted here, I come with a bit simplified and sanitized version.

First, we create a function for the posts_where filter which allows you to only show posts matching specific conditions:

function cc_post_title_filter($where, &$wp_query) { global $wpdb; if ( $search_term = $wp_query->get( 'cc_search_post_title' ) ) { $where .= ' AND ' . $wpdb->posts . '.post_title LIKE \'%' . $wpdb->esc_like( $search_term ) . '%\''; } return $where; }

Now we add cc_search_post_title into our query arguments:

$args = array( 'cc_search_post_title' => $search_term, // search post title only 'post_status' => 'publish', );

And finally wrap the filter around the query:

add_filter( 'posts_where', 'cc_post_title_filter', 10, 2 ); $query = new WP_Query($args); remove_filter( 'posts_where', 'cc_post_title_filter', 10 );

Using get_posts()

Certain functions which retrieve posts do not run filters, so the posts_where filter functions you attach will not modify the query. If you plan to use get_posts() to query your posts, you need to set suppress_filters to false in your argument array:

$args = array( 'cc_search_post_title' => $search_term, 'suppress_filters' => FALSE, 'post_status' => 'publish', );

Now you can use get_posts():

add_filter( 'posts_where', 'cc_post_title_filter', 10, 2 ); $posts = get_posts($args); remove_filter( 'posts_where', 'cc_post_title_filter', 10 );

What about the s parameter?

The s parameter is available:

$args = array( 's' => $search_term, );

While adding your search term into the s parameter work and it will search the post title, it will also search the post content.

What about the title parameter which was added with WP 4.4?

Passing a search term into the title parameter:

$args = array( 'title' => $search_term, );

Is case sensitive and LIKE, not %LIKE%. This mean search for hello will not return post with title Hello World or Hello.
- Excelente.Estababuscando 'post_title' comoparámetro y,obviamente,noencontrénada.
  
  Excellent. I was looking for 'post_title' as a parameter and, obviously, didn't find anything.

Basándomeen otras respuestas antes que yo,paraproporcionarflexibilidaden la situaciónen la que deseabuscar unapublicación que contiene unapalabraen unmetacampo Oen eltítulo de lapublicación,le doyesa opción através del argumento "title_filter_relation". Enestaimplementación,solopermitoentradas "O" o "Y" con un valorpredeterminado de "Y".

 function title_filter($where, &$wp_query){
    global $wpdb;
    if($search_term = $wp_query->get( 'title_filter' )){
        $search_term = $wpdb->esc_like($search_term); //instead of esc_sql()
        $search_term = ' \'%' . $search_term . '%\'';
        $title_filter_relation = (strtoupper($wp_query->get( 'title_filter_relation'))=='OR' ? 'OR' : 'AND');
        $where .= ' '.$title_filter_relation.' ' . $wpdb->posts . '.post_title LIKE '.$search_term;
    }
    return $where;
}

Aquí hay unejemplo del códigoen acciónpara untipo depublicaciónmuy simple "faq" donde lapreguntaeseltítulo de lapublicación:

 add_filter('posts_where','title_filter',10,2);
$s1 = new WP_Query( array(
    'post_type' => 'faq',
    'posts_per_page' => -1,
    'title_filter' => $q,
    'title_filter_relation' => 'OR',
    'post_status' => 'publish',
    'orderby'     => 'title', 
    'order'       => 'ASC',
    'meta_query' => array(
        'relation' => 'OR',
        array(
            'key' => 'faq_answer',
            'value' => $q,
            'compare' => 'LIKE'
        )
    )
));
remove_filter('posts_where','title_filter',10,2);

Building on other answers before me, to provide flexibility in the situation where you want to search a post that contains a word in a meta field OR in the title of the post, I give that option via the argument "title_filter_relation." In this implementation, I only allow for "OR" or "AND" inputs with a default of "AND."

function title_filter($where, &$wp_query){
    global $wpdb;
    if($search_term = $wp_query->get( 'title_filter' )){
        $search_term = $wpdb->esc_like($search_term); //instead of esc_sql()
        $search_term = ' \'%' . $search_term . '%\'';
        $title_filter_relation = (strtoupper($wp_query->get( 'title_filter_relation'))=='OR' ? 'OR' : 'AND');
        $where .= ' '.$title_filter_relation.' ' . $wpdb->posts . '.post_title LIKE '.$search_term;
    }
    return $where;
}

Here's an example of the code in action for a very simple post type "faq" where the question is the post title itself:

add_filter('posts_where','title_filter',10,2);
$s1 = new WP_Query( array(
    'post_type' => 'faq',
    'posts_per_page' => -1,
    'title_filter' => $q,
    'title_filter_relation' => 'OR',
    'post_status' => 'publish',
    'orderby'     => 'title', 
    'order'       => 'ASC',
    'meta_query' => array(
        'relation' => 'OR',
        array(
            'key' => 'faq_answer',
            'value' => $q,
            'compare' => 'LIKE'
        )
    )
));
remove_filter('posts_where','title_filter',10,2);

Buenainformación,agregando "variables de consulta"personalizadas a los argumentos de consultapasados a `WP_Query`parapoder acceder aellos dentro delfiltro`posts_where`.

Good insight, adding custom "query vars" to the query args passed to `WP_Query` in order to be able to access them within the `posts_where` filter.

Resolveríaesto con unfiltroen WP_Query.Uno que detecta una variable de consulta adicional y la usa comoprefijo deltítulo.

 add_filter( 'posts_where', 'wpse18703_posts_where', 10, 2 );
function wpse18703_posts_where( $where, &$wp_query )
{
    global $wpdb;
    if ( $wpse18703_title = $wp_query->get( 'wpse18703_title' ) ) {
        $where .= ' AND ' . $wpdb->posts . '.post_title LIKE \'' . esc_sql( $wpdb->esc_like( $wpse18703_title ) ) . '%\'';
    }
    return $where;
}

Deestamanera aúnpuede llamar a WP_Query,simplementepaseeltítulo comoel argumento wpse18703_title (o cambieelnombre a algomás corto).

I would solve this with a filter on WP_Query. One that detects an extra query variable and uses that as the prefix of the title.

add_filter( 'posts_where', 'wpse18703_posts_where', 10, 2 );
function wpse18703_posts_where( $where, &$wp_query )
{
    global $wpdb;
    if ( $wpse18703_title = $wp_query->get( 'wpse18703_title' ) ) {
        $where .= ' AND ' . $wpdb->posts . '.post_title LIKE \'' . esc_sql( $wpdb->esc_like( $wpse18703_title ) ) . '%\'';
    }
    return $where;
}

This way you can still call WP_Query, you just pass the title as the wpse18703_title argument (or change the name to something shorter).

A éste lefalta de algunamanerael `$ wpdb->prepare ()`.

This one is somehow missing the `$wpdb->prepare()`.

@kaiser: Hapasadomuchotiempo,pero creo queestonofueposible con `prepare ()`.`$ wpdb->prepare ('LIKE"% s %% "','banana')` devolvería `" LIKE ''banana '%' "`,así quetenemos que construir la consultanosotrosmismos y hacerelescapetambién.

@kaiser: It's been a long time, but I think this was not possible with `prepare()`. `$wpdb->prepare('LIKE "%s%%"', 'banana')` would return `"LIKE ''banana'%'"`, so we have to construct the query ourselves, and do the escaping too.

@JanFabry ¡Feliz de verte denuevo!:) Pasa un ratoen el chat,¿eh?StopPressestaríafeliz de verte.Sobreeso `prepare ()`.Sí,esoes complicado ytuve queintentarlo varias veces,antes de solucionarlo.De algo que acabo de hacer: `$ wpdb->prepare ('AND {$ wpdb->posts} .post_title LIKE% s',esc_sql ('%'. Like_escape (trim ($term)). '%'))`.Yestoybastante seguro de que `esc_sql ()`esinnecesario y simplementeparanoico.

@JanFabry Happy to see you agaaaaaaaain! :) Drop by in chat some time, hm? StopPress would be happy to see you. About that `prepare()`. Yeah, that's tricky and I had to try that several times, before I got around it. From something I just made: `$wpdb->prepare( ' AND {$wpdb->posts}.post_title LIKE %s ', esc_sql( '%'.like_escape( trim( $term ) ).'%' ) )`. And I'm pretty sure the `esc_sql()` is unnecessary and just paranoid.

Parece quenopuedebuscar una cadena con `` '' (apóstrofe) dentro.¿Supongo queesporescapar?Todavíanoencontré la solución

It seems that you can't search a string with `'` (apostrophe) inside. I guess it's because of escaping ? I didn't find the solution yet
