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：
/*

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

function initps(){

if (document.addeventlistener) {

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。
