「post_titleLIKE'something％ '」を使用したWP_Query？

WP_QueryでLIKEを使用してpost_titleを実行する必要があります.

この通常のpost_titleから始めました:

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

しかし、私が実際にやりたいことは、SQLでは次のようになります.

 $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);

出力には期待する結果が出力されますが、通常の<?php while ( $wp_query->have_posts() ) : $wp_query->the_post(); ?>で結果を表示します.
そして、それは$wpdb->get_results()では機能しません.

ここで説明したことをどのように達成できますか?

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?

簡略化:

 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;

コードと一緒に説明を含めてください.

Please include an explanation along with your code.

'esc_sql(like_escape(')の代わりに '$ wpdb->esc_like('を使用します

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

@fdrvあなたは正しいですが、wp docsによると、$ wpdb->esc_likeにはまだesc_sql()が必要です.したがって、正しいコードはesc_sql($ wpdb->esc_like($ search_term))だと思います.

@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 ) )

esc_sql()は4.0以降で非推奨になったため、WordPress4.0以降で作業したこのコードを更新したいと考えています.

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; }

残りは同じです.

また、WP_Query引数内で s 変数を使用して検索語を渡すことができることも指摘したいと思います.これにより、私が信じる投稿タイトルも検索されます.

このように:

$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);

ここにいくつかの脆弱なソリューションが掲載されているので、少し簡略化してサニタイズしたバージョンが付属しています.

最初に、posts_whereフィルターの関数を作成します.これにより、特定の条件に一致する投稿のみを表示できます.

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; }

ここで、クエリ引数にcc_search_post_titleを追加します.

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

最後に、クエリの周りにフィルタをラップします:

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

get_posts()の使用

投稿を取得する特定の関数はフィルターを実行しないため、アタッチするposts_whereフィルター関数はクエリを変更しません. get_posts()を使用して投稿をクエリする場合は、引数の配列でsuppress_filtersをfalseに設定する必要があります.

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

これで、get_posts()を使用できます:

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

sパラメータはどうですか?

sパラメータが利用可能です:

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

検索語をsパラメータに追加すると、投稿のタイトルが検索されますが、投稿のコンテンツも検索されます.

WP4.4で追加されたtitleパラメーターはどうですか?

検索語をtitleパラメータに渡す:

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

大文字と小文字が区別され、LIKEではなく%LIKE%です.つまり、helloを検索しても、タイトルがHello WorldまたはHelloの投稿は返されません.
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.

私の前にある他の回答に基づいて、メタフィールドまたは投稿のタイトルに単語を含む投稿を柔軟に検索するために、引数「title_filter_relation」を使用してそのオプションを指定します.この実装では、デフォルトが「AND」の「OR」または「AND」入力のみを許可します.

 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;
}

質問が投稿のタイトル自体である、非常に単純な投稿タイプ「faq」の実際のコードの例を次に示します.

 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);

`posts_where`フィルター内でそれらにアクセスできるようにするために、` WP_Query`に渡されるクエリ引数にカスタムの「クエリ変数」を追加することは良い洞察です.

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.

WP_Queryのフィルターを使用してこれを解決します.余分なクエリ変数を検出し、それをタイトルのプレフィックスとして使用するもの.

 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;
}

この方法でもWP_Queryを呼び出すことができ、タイトルをwpse18703_title引数として渡す(または名前を短いものに変更する)だけです.

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).

これはどういうわけか `$ wpdb->prepare()`がありません.

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

@kaiser:久しぶりですが、 `prepare()`では不可能だったと思います.`$ wpdb->prepare( 'LIKE"％s %% "'、 'banana')`は `" LIKE''banana '％' "`を返すので、自分でクエリを作成し、エスケープも行う必要があります.

@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お会いできてうれしいですagaaaaaaaain！:)いつかチャットに立ち寄ってくださいね?StopPressはあなたに会えてうれしいです.その `prepare()`について.ええ、それはトリッキーで、私はそれを回避する前にそれを数回試さなければなりませんでした.私が今作ったものから: `$ wpdb->prepare( 'AND {$ wpdb->posts} .post_title LIKE％s'、esc_sql( '％'.like_escape(trim($term)). '％'))`.そして、私は `esc_sql()`が不必要で、ただ妄想的であると確信しています.

@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.

`'`(アポストロフィ)が含まれている文字列は検索できないようです.逃げたからだと思いますか?私はまだ解決策を見つけられませんでした

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
