分享wordpress添加游客投稿页面功能

作者：佚名网站建设问答编辑：admin 更新时间：2022-07-23

相信有不少站长朋友都或多或少接触过wordpress吧，其中很多人都需要一个投稿页面，当然其中好处不言而喻了。网上有的投稿插件是英文的，有的类似于留言本，有的会显示乱码，而今天笔者就教大家自己做一个插件来实现投稿功能。

首先新建submit_posts_ajax.php，将以下内容复制进去：

<?php function submit_posts_ajax(){ if($_POST['submit_posts_ajax']=='yinheli'){ $title=strip_tags(trim($_POST['post_title'])); $name=trim($_POST['your_name']); $mail=trim($_POST['your_email']); $site=trim($_POST['your_site']); $content=stripslashes(trim($_POST['post_content'])); $tags=strip_tags(trim($_POST['post_tags'])); global $wpdb; $db="SELECT post_title FROM $wpdb->posts WHERE post_title = '$title' LIMIT 1"; if ($wpdb->get_var($db)){ echo '<div class="ps_errormsg">发现重复文章.你已经发表过了.或者存在该文章</div>'; die(); } if(!empty($site)){ if(substr($site, 0, 7) != 'http://') $site= 'http://'.$site; $author='<a href="'.$site.'" title="'.$name.'">'.$name.'</a>'; }else{ $author=$name; } $info='<div class="post_submit_info">感谢: '.$author.' 的供稿.</div>'."\n\n"; if(isset($_POST['post_submit'])){ //错误判断 if($title==''){ echo '<div class="ps_errormsg">错误:没有填写标题!</div>'; die(); } elseif($mail==''){ echo '<div class="ps_errormsg">错误:没有填写邮箱地址.</div>'; die(); } elseif($content==''){ echo '<div class="ps_errormsg">错误:还没有填写内容!!!</div>'; die(); }else{ //提交数据 $content=$info.$content; $submitdata=array( 'post_title' =>$title, 'post_content' =>$content, 'tags_input' =>$tags, 'post_status' => 'pending' ); $post_id = wp_insert_post($submitdata,$wp_error = false); $subject='您给[ '.get_option('blogname').' ]写了篇文章标题是: '.$title; $message='非常感谢您的供稿.您的稿件已经提交.等待管理员的审核. 以下是您提交的内容:<hr>'.stripslashes(trim($_POST['post_content'])); yinheli_sendmail_ps($mail,$subject,$message); echo '<div class="ps_msg">非常感谢您的供稿.您的稿件已经提交.等待管理员的审核.请耐心等待.</div>'; @header('Content-type: ' . get_option('html_type') . '; charset=' . get_option('blog_charset')); die(); } } if(isset($_POST['post_review'])){ if(''==$content){ echo '还没有填写内容'; die(); } if(''==$tags) $tags='您还没有填写标签 (Tags)'; echo '<div class="ps_reviewmsg"> <h2>'.$title.'</h2> <div class="ps_reviewcontent"> '.$info.$content.' <p class="ps_reviewtags">标签:'.$tags.'</p> </div> </div>'; die(); } die(); } } function yinheli_sendmail_ps($to,$subject,$message){ $blogname = get_option('blogname'); $charset = get_option('blog_charset'); $ps_sendmail_headers = "From: $blogname \n" ; $ps_sendmail_headers .= "MIME-Version: 1.0\n"; $ps_sendmail_headers .= "Content-Type: text/html;charset=\"$charset\"\n"; return @wp_mail($to, $subject, $message, $ps_sendmail_headers); } function submit_posts_load_js(){ echo "\n".'<script type="text/javascript" src="' . get_bloginfo('wpurl') . '/wp-content/plugins/submit_posts/submit_posts.js"></script>'."\n"; } add_action('init', 'submit_posts_ajax'); require_once('submit_posts.php'); function submit_posts_display(){ submit_posts_load_js(); $submit_posts_html=submit_posts_html(); return $submit_posts_html; } add_shortcode('submit_posts','submit_posts_display'); ?>

接下来新建submit_posts.php，同样将以下内容复制进去：

最后再新建submit_posts.js，将以下内容复制进去：

/* Author: 89948 Update: 2009/04/11 Author URI: http://www.89948.net/ */ (function(){ if(!window.YHLJSPS) window['YHLJSPS']={}; function isCompatible(other) { if( other===false || !Array.prototype.push || !Object.hasOwnProperty || !document.createElement || !document.getElementsByTagName ) { alert('TR- if you see this message isCompatible is failing incorrectly.'); return false; } return true; } function $(id){ return document.getElementById(id); } var xmlHttp; function getXmlHttpObject(){ var xmlHttp = null; try { xmlHttp = new XMLHttpRequest(); } catch(e) { try { xmlHttp = new ActiveXObject("Msxml2.XMLHTTP"); } catch(e) { xmlHttp = new ActiveXObject("Microsoft.XMLHTTP"); } } return xmlHttp; } function setStyle(element, key, value) { element.style[key] = value; } function addEvent(node,type,listener){ if(!isCompatible()) { return false } if(node.addEventListener){ node.addEventListener(type,listener,false); return true; }else if(node.attachEvent){ node['e'+type+listener]=listener; node[type+listener]=function(){ node['e'+type+listener](window.event); } node.attachEvent('on'+type,node[type+listener]); return true; } } function insertAfter(node, referenceNode) { if(!(node = $(node))) return false; if(!(referenceNode = $(referenceNode))) return false; return referenceNode.parentNode.insertBefore(node, referenceNode.nextSibling); }; function preventDefault(eventObject) { eventObject = eventObject || getEventObject(eventObject); if(eventObject.preventDefault) { eventObject.preventDefault(); } else { eventObject.returnValue = false; } } function formToRequestString(form_obj,val){ var query_string=''; var and='&'; for (i=0;i<form_obj.length ;i++ ){ e=form_obj[i]; if (e.name!='' && e.type!='submit'){ if (e.type=='select-one'){ element_value=e.options[e.selectedIndex].value; }else if (e.type=='checkbox' || e.type=='radio'){ if (e.checked==false){ break; }element_value=e.value; }else{ element_value=e.value; } query_string+=and+encodeURIComponent(e.name)+'='+encodeURIComponent(element_value); } } return query_string; } function setopacity(node,opacity){ setStyle(node, 'opacity', opacity); setStyle(node, 'MozOpacity', opacity); setStyle(node, 'KhtmlOpacity', opacity); setStyle(node, 'filter', 'alpha(opacity=' + opacity * 100 + ')'); return; } function stateChangeListener(){ var r_msg=$('ps_msg'); var the_form=$('post_submit_form'); if(xmlHttp.readyState==1){ r_msg.innerHTML='数据载入中,请稍候...'; setopacity(the_form,0.8); $('post_submit').disabled=true; window.scrollTo(0,r_msg.offsetTop+15); }else if(xmlHttp.readyState==4 && xmlHttp.status==200){ r_msg.innerHTML=xmlHttp.responseText; setopacity(the_form,1); setTimeout(function(){$('post_submit').disabled=false;},1000); }else if(xmlHttp.status!=200){ alert('呃出错了 (建议您保存好文章再刷新浏览器.) 错误信息:'+xmlHttp.statusText); } } function submitactiontype(type){ var A=formToRequestString($('post_submit_form'))+'&'+encodeURIComponent($(type).name)+'='+encodeURIComponent($(type).value); return A; } function ps_submit(action){ xmlHttp = getXmlHttpObject(); if (xmlHttp == null) { alert ("Oop! Browser does not support HTTP Request.") return; } var url=window.location.href; if(action=='post_submit'){ var senddata=submitactiontype(action); } if(action=='post_review'){ var senddata=submitactiontype(action); } xmlHttp.onreadystatechange=function(){ stateChangeListener(); } xmlHttp.open("POST", url, true); xmlHttp.setRequestHeader('Content-Type','application/x-www-form-urlencoded'); xmlHttp.send(senddata); } function initps(){ addEvent($('post_submit'),'click',function(W3CEvent){ ps_submit(action='post_submit'); //alert(action); preventDefault(W3CEvent); }); addEvent($('post_review'),'click',function(W3CEvent){ ps_submit(action='post_review'); //alert(action); preventDefault(W3CEvent); }); } if (document.addEventListener) { document.addEventListener("DOMContentLoaded", initps, false); } else if (/MSIE/i.test(navigator.userAgent)) { document.write('<script id="__ie_onload_for_post_posts" defer src="javascript:void(0)"></script>'); var script = $('__ie_onload_for_post_posts'); script.onreadystatechange = function() { if (this.readyState == 'complete') { initps(); } } } else if (/WebKit/i.test(navigator.userAgent)) { var _timer = setInterval( function() { if (/loaded|complete/.test(document.readyState)) { clearInterval(_timer); initps(); } }, 10); } else { window.onload = function(e) { initps(); } } })();

把以上三个文件保存在submit_posts文件夹内，上传至插件目录，并进后台安装该插件。使用时只需要新建页面并输入[submit_posts]即可调用出。
