不使用wp_head将内容放入header.php

时间：2016-02-25 作者：Zach Smith

我正在构建一个插件。我必须在标题中输出某些内容。主题的php文件取决于我是否要编写。然而，我还没有达到这一点。我只是为了将函数推入页眉而学习的。php我必须使用wp_head. 不幸的是，当我这样做的时候，我得到了WordPress处理的许多额外的东西塞进了wp_head 作用

是否有其他方法将插件中的变量发布到标题中。php不使用wp_head?

删除wp\\u头会产生一些负面影响，因为它不允许您使用wordpress上几乎90%的插件。组织。此外，您看到的一些代码仅在您登录时显示（除非您的主题专门添加它）。例如，底部的dashicons、open SAN和管理栏样式表以及内联样式都在那里，因此您可以使用前端的管理栏。

以下是一些选项。

1. Custom header - This is a safe alternative if you don\'t want wp_head in some of your pages, but still want to be able to use it and other wordpress plugins on other templates.

<创建文件header-custom.php 在主题文件夹中，不包括wp_headpage template 使用调用该标题<?php get_header( \'custom\' ); ?><?php do_action(\'custom_head\'); ?> 然后在插件中以与wp\\u head相同的方式钩住它

示例
function my_plugin_custom_head_action() { // do stuff here } add_action(\'custom_head\', \'my_plugin_custom_head_action\');
还有一个plugin 这使得使用自定义挂钩/动作的过程非常简单。
<小时>2. Remove stuff you don\'t want from wp_head
// Remove emojis function disable_emojis_wp_head() { remove_action( \'wp_head\', \'print_emoji_detection_script\', 7 ); remove_action( \'admin_print_scripts\', \'print_emoji_detection_script\' ); remove_action( \'wp_print_styles\', \'print_emoji_styles\' ); remove_action( \'admin_print_styles\', \'print_emoji_styles\' ); remove_filter( \'the_content_feed\', \'wp_staticize_emoji\' ); remove_filter( \'comment_text_rss\', \'wp_staticize_emoji\' ); remove_filter( \'wp_mail\', \'wp_staticize_emoji_for_email\' ); add_filter( \'tiny_mce_plugins\', \'disable_emojis_wp_tinymce\' ); } add_action( \'init\', \'disable_emojis_wp_head\' ); function disable_emojis_wp_tinymce( $plugins ) { if ( is_array( $plugins ) ) { return array_diff( $plugins, array( \'wpemoji\' ) ); } else { return array(); } } // Remove other crap in your example add_action( \'get_header\', function() { remove_action(\'wp_head\', \'rsd_link\'); // Really Simple Discovery service endpoint, EditURI link remove_action(\'wp_head\', \'wp_generator\'); // XHTML generator that is generated on the wp_head hook, WP version remove_action(\'wp_head\', \'feed_links\', 2); // Display the links to the general feeds: Post and Comment Feed remove_action(\'wp_head\', \'index_rel_link\'); // index link remove_action(\'wp_head\', \'wlwmanifest_link\'); // Display the link to the Windows Live Writer manifest file. remove_action(\'wp_head\', \'feed_links_extra\', 3); // Display the links to the extra feeds such as category feeds remove_action(\'wp_head\', \'start_post_rel_link\', 10, 0); // start link remove_action(\'wp_head\', \'parent_post_rel_link\', 10, 0); // prev link remove_action(\'wp_head\', \'adjacent_posts_rel_link\', 10, 0); // relational links 4 the posts adjacent 2 the currentpost remove_action(\'template_redirect\', \'wp_shortlink_header\', 11); remove_action(\'wp_head\', \'adjacent_posts_rel_link_wp_head\', 10, 0 ); }, 99); // Remove adminbar inline css on frontend function removeinline_adminbar_css_frontend() { if ( has_filter( \'wp_head\', \'_admin_bar_bump_cb\' ) ){ remove_filter( \'wp_head\', \'_admin_bar_bump_cb\' ); } } add_filter( \'wp_head\', \'removeinline_adminbar_css_frontend\', 1 );
如果您想删除rest api链接，我相信这会起作用：
remove_action( \'template_redirect\', \'rest_output_link_header\', 11, 0 );
看到这个了吗WPSE post here 对于其他解决方案，请删除rest api。

@布莱恩·威利斯有一个很好的答案，可以让你从wp_head. 在大多数情况下，这可能是一种更好的方法，但如果你真的不需要所有额外的东西wp_head(), 你可以决定不带它去。
但是，如果删除wp_head 完全从标题或模板中，您将无法使用如下挂钩wp_enqueue_scripts, 这使得在模板中加载自己的CSS和JS文件变得容易。这就是为什么如果你wp_head 在你的模板中，除去你需要的以外的所有东西，你的模板将输出一个干净的头部，同时允许你从中受益wp_head().
这样，您就不必识别和删除WordPress或其他主题或插件加载到模板上的所有特定内容。
Remove all functions from wp_head hook, and maybe from wp_footer hook except the ones you need.
function unhook_wp_head_footer() { if ( /* some condition */ ) { global $wp_filter; // it contains all hooks foreach ( $wp_filter[\'wp_head\']->callbacks as $priority => $wp_head_hooks ) { if ( is_array( $wp_head_hooks ) ){ foreach ( $wp_head_hooks as $idx => $wp_head_hook ) { if ( $wp_head_hook[\'function\'] !== \'wp_enqueue_scripts\' // keep functionality of wp_enqueue_scripts && $wp_head_hook[\'function\'] !== \'wp_print_head_scripts\' // to allow wp_enqueue_scripts load js inside the head element && $wp_head_hook[\'function\'] !== \'wp_print_styles\' ) { // to allow wp_enqueue_scripts load css inside the head element remove_action( \'wp_head\', $wp_head_hook[\'function\'], $priority ); } } } } foreach ( $wp_filter[\'wp_footer\']->callbacks as $priority => $wp_footer_hooks ) { if ( is_array( $wp_footer_hooks ) ) { foreach ( $wp_footer_hooks as $idx => $wp_footer_hook ) { if ( $wp_footer_hook[\'function\'] !== \'wp_print_footer_scripts\' ) { // to allow wp_enqueue_scripts load scripts in the footer remove_action( \'wp_footer\', $wp_footer_hook[\'function\'], $priority ); } } } } } } add_action( \'wp\', \'unhook_wp_head_footer\' );
In case of keeping wp_enqueue_scripts, dequeue all CSS and JS that you don\'t need.
// dequeue all assets if not from your plugin public function dequeue_assets() { if ( /* some condition */ ) { global $wp_styles, $wp_scripts; $prefix = \'plugin-handle\'; // your plugin name used as prefix in $handle of wp_enqueue_script or wp_enqueue_style function calls foreach ( $wp_styles->queue as $handle ) { if ( strpos( $handle, $prefix ) !== 0 ) { wp_deregister_style( $handle ); wp_dequeue_style( $handle ); } } foreach ( $wp_scripts->queue as $handle ) { if ( strpos( $handle, $prefix ) !== 0 ) { wp_deregister_script( $handle ); wp_dequeue_script( $handle ); } } } } add_action( \'wp_enqueue_scripts\', \'dequeue_assets\', 9999 );
