在functions.php中的Wordpress var_dump [英] Wordpress var_dump in functions.php

问题描述

我需要在 WP 的自定义函数过滤器中执行 var_dump，但是，结果显示在哪里?代码正在运行，因为我可以看到搜索结果结构与代码存在时和不存在时的差异

I need to do a var_dump in a custom function filter in WP but, where is the results shown? The code is working because I can see the search result structure difference from when the code is present and not

    add_filter('relevanssi_hits_filter', 'products_first');
function products_first($hits) {
    $types = array();

    $types['section1'] = array();
    $types['section2'] = array();
    $types['section3'] = array();
    $types['section4'] = array();

    // Split the post types in array $types
    if (!empty($hits)) {
        foreach ($hits[0] as $hit) {
            array_push($types_1[$hit->post_type], $hit);
        }
    }

    // Merge back to $hits in the desired order
    var_dump($types);
    $hits[0] = array_merge($types['section1'], $types['section2'], $types['section3'], $types['section4']);
    return $hits;
}

推荐答案

尝试在 var_dump 之后立即终止流程，这通常可以帮助我更轻松地调试:

Try killing the flow right after the var_dump, that ussually helps me debug easier:

var_dump($types);
die("products_first_ends");

这样，如果 var_dump 之后的内容在 var dump 之上呈现，它就不会被它覆盖.

That way if something after your var_dump is rendering on top of the var dump it wont get covered by it.
