wordpress添加打字烟花特效

今天，有人在问本站的打字特效怎么弄的，现在把代码贴出来共享。

一、首先新建一个js文件，粘贴下面的代码，并上传到你用的主题的js文件夹中

/**
 * 给wordpress博客网站添加评论输入礼花及震动特效
 * https://myqqjd.com
 */
(function webpackuniversalmoduledefinition(root,factory){if(typeof exports==='object'&&typeof module==='object')module.exports=factory();else if(typeof define==='function'&&define.amd)define([],factory);else if(typeof exports==='object')exports["powermode"]=factory();else root["powermode"]=factory()})(this,function(){return(function(modules){var installedmodules={};function __webpack_require__(moduleid){if(installedmodules[moduleid])return installedmodules[moduleid].exports;var module=installedmodules[moduleid]={exports:{},id:moduleid,loaded:false};modules[moduleid].call(module.exports,module,module.exports,__webpack_require__);module.loaded=true;return module.exports}__webpack_require__.m=modules;__webpack_require__.c=installedmodules;__webpack_require__.p="";return __webpack_require__(0)})([function(module,exports,__webpack_require__){'use strict';var canvas=document.createelement('canvas');canvas.width=window.innerwidth;canvas.height=window.innerheight;canvas.style.csstext='position:fixed;top:0;left:0;pointer-events:none;z-index:999999';window.addeventlistener('resize',function(){canvas.width=window.innerwidth;canvas.height=window.innerheight});document.body.appendchild(canvas);var context=canvas.getcontext('2d');var particles=[];var particlepointer=0;powermode.shake=true;function getrandom(min,max){return math.random()*(max-min) min}function getcolor(el){if(powermode.colorful){var u=getrandom(0,360);return'hsla(' getrandom(u-10,u 10) ', 100%, ' getrandom(50,80) '%, ' 1 ')'}else{return window.getcomputedstyle(el).color}}function getcaret(){var el=document.activeelement;var bcr;if(el.tagname==='textarea'||(el.tagname==='input'&&el.getattribute('type')==='text')){var offset=__webpack_require__(1)(el,el.selectionstart);bcr=el.getboundingclientrect();return{x:offset.left bcr.left,y:offset.top bcr.top,color:getcolor(el)}}var selection=window.getselection();if(selection.rangecount){var range=selection.getrangeat(0);var startnode=range.startcontainer;if(startnode.nodetype===document.text_node){startnode=startnode.parentnode}bcr=range.getboundingclientrect();return{x:bcr.left,y:bcr.top,color:getcolor(startnode)}}return{x:0,y:0,color:'transparent'}}function createparticle(x,y,color){return{x:x,y:y,alpha:1,color:color,velocity:{x:-1 math.random()*2,y:-3.5 math.random()*2}}}function powermode(){{var caret=getcaret();var numparticles=5 math.round(math.random()*10);while(numparticles--){particles[particlepointer]=createparticle(caret.x,caret.y,caret.color);particlepointer=(particlepointer 1)p0}}{if(powermode.shake){var intensity=1 2*math.random();var x=intensity*(math.random()>0.5?-1:1);var y=intensity*(math.random()>0.5?-1:1);document.body.style.marginleft=x 'px';document.body.style.margintop=y 'px';settimeout(function(){document.body.style.marginleft='';document.body.style.margintop=''},75)}}};powermode.colorful=false;function loop(){requestanimationframe(loop);context.clearrect(0,0,canvas.width,canvas.height);for(var i=0;iparseint(computed.height))style.overflowy='scroll'}else{style.overflow='hidden'}div.textcontent=element.value.substring(0,position);if(element.nodename==='input')div.textcontent=div.textcontent.replace(/\s/g,"\u00a0");var span=document.createelement('span');span.textcontent=element.value.substring(position)||'.';div.appendchild(span);var coordinates={top:span.offsettop parseint(computed['bordertopwidth']),left:span.offsetleft parseint(computed['borderleftwidth'])};if(debug){span.style.backgroundcolor='#aaa'}else{document.body.removechild(div)}return coordinates}if(typeof module!="undefined"&&typeof module.exports!="undefined"){module.exports=getcaretcoordinates}else{window.getcaretcoordinates=getcaretcoordinates}}())}])});

二、编辑主题，在主题页脚footer.php的body前加上下面的代码保存就可以了。

powermode.colorful = true; // ture 为启用礼花特效
powermode.shake = false; // false 为禁用震动特效

over!效果看本站！

wordpress 禁止某些用户登录

对于饱受沧桑的老站长一定深感做站不易，尤其是我们小站长在发展中有时难免有坏坏来捣蛋，让站长愁困许久四处请大神，今天呢咱们说个wordpress 禁止某些用户登录让捣蛋者禁止登陆不让他捣蛋耍坏坏、、、
以下代码丢到函数文件functions.php：

/**
 * wordpress 禁止某些用户登录
 */
//在资料页面添加选项
function lxtx_rc_admin_init(){ 
	// 编辑用户资料
	add_action( 'edit_user_profile', 'lxtx_rc_edit_user_profile' );
	add_action( 'edit_user_profile_update', 'lxtx_rc_edit_user_profile_update' ); 
}
add_action('admin_init', 'lxtx_rc_admin_init' );
//在个人资料页面添加一个复选框
function lxtx_rc_edit_user_profile() {
	if ( !current_user_can( 'edit_users' ) ) {
		return;
	} 
	global $user_id; 
	// 用户不能禁止自己
	$current_user = wp_get_current_user();
	$current_user_id = $current_user->id;
	if ( $current_user_id == $user_id ) {
		return;
	}
	?>
	
权限设置
	

	

		
禁止用户登录
		
 /> 请谨慎操作，选中则禁止！
	
	
	id;
	if ( $current_user_id == $user_id ) {
		return;
	} 
	// 锁定
	if( isset( $_post['lxtx_rc_ban'] ) && $_post['lxtx_rc_ban'] = 'on' ) {
		lxtx_rc_ban_user( $user_id );
	} else { // 解锁
		lxtx_rc_unban_user( $user_id );
	} 
}
//禁止用户
function lxtx_rc_ban_user( $user_id ) { 
	$old_status = lxtx_rc_is_user_banned( $user_id ); 
	// 更新状态
	if ( !$old_status ) {
		update_user_option( $user_id, 'lxtx_rc_banned', true, false );
	}
}
//解禁用户
function lxtx_rc_unban_user( $user_id ) { 
	$old_status = lxtx_rc_is_user_banned( $user_id ); 
	// 更新状态
	if ( $old_status ) {
		update_user_option( $user_id, 'lxtx_rc_banned', false, false );
	}
}
//判断用户是否被禁止
function lxtx_rc_is_user_banned( $user_id ) {
	return get_user_option( 'lxtx_rc_banned', $user_id, false );
}
//阻止已禁止的用户登录
function lxtx_rc_authenticate_user( $user ) { 
	if ( is_wp_error( $user ) ) {
		return $user;
	} 
	// 如果用户被禁止，则返回错误提示
	$banned = get_user_option( 'lxtx_rc_banned', $user->id, false );
	if ( $banned ) {
		return new wp_error( 'lxtx_rc_banned', __('抱歉，该用户被禁止登录！请联系站长解禁。', 'rc') );
	} 
	return $user;
}
//将该函数挂载到 wp_authenticate_user 钩子
add_filter( 'wp_authenticate_user', 'lxtx_rc_authenticate_user', 1 );

然后，管理员在后台“编辑用户”菜单里看到我们增加的这个选项了，可以禁止某用户登陆。选中后，则会禁止该用户登录！并且该用户在登录时，会看到这个提示信息：“抱歉，该用户被禁止登录！请联系站长解禁。”

wordpress开启cdn后评论失败怎么办？

wordpress 博客如果将静态资源如 js 文件等采用 cdn 加速的话，一般都会出现评论不成功的情况，这是因为评论时所获取的 commonts-ajax.js 路径不正确导致，所以解决的办法有两个：

方法一：在 cdn 中设置不缓存 commonts-ajax.js 文件即可；

方法二：修改 commonts-ajax.js 文件，打开当前主题所使用的 commonts-ajax.js 文件，找到以下代码：

var i = 0, got = -1, len = document.getelementsbytagname('script').length;
while ( i <= len && got == -1){
    var js_url = document.getelementsbytagname('script')[i].src,
            got = js_url.indexof('comments-ajax.js'); i   ;
}

在后面添加一句

js_url = js_url.replace('res.yigujin.cn','www.yigujin.cn');

变成

var i = 0, got = -1, len = document.getelementsbytagname('script').length;
while ( i <= len && got == -1){
    var js_url = document.getelementsbytagname('script')[i].src,
            got = js_url.indexof('comments-ajax.js'); i   ;
}
js_url = js_url.replace('res.yigujin.cn','www.yigujin.cn');

保存好文件并刷新该文件的缓存后即可解决评论失败的问题。如果 cdn 的域名不唯一经常变动，那么可以直接把前面那段代码改成：

var i = 0, got = -1, len = document.getelementsbytagname('script').length;
while ( i <= len && got == -1){
    var js_url = document.getelementsbytagname('script')[i].src,
            got = js_url.indexof('comments-ajax.js'); i   ;
var dm = js_url.match(/http:\/\/([^\/] )\//i);
js_url = js_url.replace(dm[1],'www.yigujin.cn');
}

其中 a.yigujin.cn 就是所谓的 cdn 地址，www.yigujin.cn 是站点地址，记得修改成自己的地址哦。
