Question

这似乎应该是一个简单的答案，但我正在努力解决这个问题。如何在where子句中添加类别ID？我有一堆帖子类别，我想排序类别ID = 4或类别名称=餐馆。下面是我的工作$ wpdb get_results，但在where子句中没有类别ID或名称。我该如何添加？

$(document).ready(function() {

    $("#category").change(function() {
        $.ajax({
            type: "POST",
            url: $link_subcat,
            data: {cat: $(this).val()},
            success: function(data) {
                $("#subcategory").html(data);
            }
        });
    });

    $("input[name=type]").change(function() {
        $.ajax({
            type: "POST",
            url: $link_cat,
            data: {type: $('input[name="type"]:checked').val()},
            success: function(data) {
                $("#category").html(data);
            }
        });
    });

});

假设您使用的是“类别”分类，并对术语ID为4或术语名称为“Restaurants”的帖子感兴趣，则查询将如下所示：

...
LEFT JOIN wp_postmeta m4
    ON p.id = m4.post_id AND m4.meta_key = 'bOpenClose'
INNER JOIN wp_term_relationships AS tr
    ON tr.object_id = ID
INNER JOIN wp_term_taxonomy AS tt
    ON tr.term_taxonomy_id = tt.term_taxonomy_id AND tt.taxonomy = 'category'
INNER JOIN wp_terms AS t
    ON tt.term_id = t.term_id  
     WHERE (tt.term_id = 4 OR t.name = 'Restaurants') AND post_type='el2-business' HAVING distance < $thedistance ORDER BY distance");

将类别ID或名称添加到where子句$ wpdb
