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";

$ps_sendmail_headers .= "Content-Type: text/html;charset="$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：

<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：

/*

*/

(function(){

function setopacity(node,opacity){

function stateChangeListener(){

}

function submitactiontype(type){

function ps_submit(action){

var url=window.location.href;

}

xmlHttp.onreadystatechange=function(){

}

xmlHttp.open("POST", url, true);

xmlHttp.setRequestHeader('Content-Type','application/x-www-form-urlencoded');

}

function initps(){

addEvent($('post_submit'),'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。
