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>'.nn;

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: 1.0n;

$ps_sendmail_headers .= content-type: text/html;charset=$charsetn;

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：

<script type=text/javascript>

<!--

//-->

</script><?php

function submit_posts_html(){

ob_end_clean();

ob_start();

?>

<div id=ps_msg>欢迎给我供稿</div>

<form id=post_submit_form name=post_submit_form method=post action=>

<div class=row>

<input type=hidden name=submit_posts_ajax id=submit_posts_ajax value=yinheli/>

<label><input type=text name=post_title id=post_title tabindex=1 value=<?php echo strip_tags($_post['post_title']);?>/> 投稿标题(必填)</label>

</div>

<div class=row>

<label><input type=text name=your_name id=your_name tabindex=2 value=<?php echo $_post['your_name'];?> /> 您的名字或昵称</label>

</div>

<div class=row>

<label><input type=text name=your_email id=your_email tabindex=3 value=<?php echo $_post['your_email'];?> /> 您的邮箱(必填)</label>

</div>

<div class=row>

<label><input type=text name=your_site id=your_site tabindex=4 value=<?php echo $_post['your_site'];?> /> 您的网站</label>

</div>

<div class=row>

<textarea name=post_content cols=50 rows=15 id=post_content tabindex=5><?php echo stripslashes($_post['post_content']);?></textarea>

</div>

<div class=row>

<label><input type=text name=post_tags id=post_tags tabindex=6 value=<?php echo strip_tags($_post['post_tags']);?> /> 标签(tags)[每个标签用半角的逗号分开]</label>

</div>

<div id=submit_post>

<input type=submit name=post_review id=post_review value=预览 tabindex=7 />

<input type=submit name=post_submit id=post_submit value=提交 tabindex=8 />

</div>

<div style=clear:both></div>

</form>

<?php

$html=ob_get_contents();

ob_end_clean();

return $html;

}

?>

最后再新建submit_posts.js，将以下内容复制进去：

/*

author uri: 

*/

(function(){

if(!window.yhljsps) window['yhljsps']={};

alert('tr- if you see this message iscompatible is failing incorrectly.');

return false;

}

return true;

}

function $(id){

return document.getelementbyid(id);

function setstyle(element, key, value) {

element.style[key] = value;

function addevent(node,type,listener){

if(!iscompatible()) { return false }

function preventdefault(eventobject) {

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(){

}

function submitactiontype(type){

return a;

}

function ps_submit(action){

return;

var url=window.location.href;

if(action=='post_submit'){

}

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){

}

if (document.addeventlistener) {

} else if (/msie/i.test(navigator.useragent)) {

})();

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。
