相信有不少站長朋友都或多或少接觸過wordpress吧，其中很多人都需要一個投稿頁面，當然其中好處不言而喻了。網(wǎng)上有的投稿插件是英文的，有的類似于留言本，有的會顯示亂碼，而今天筆者就教大家自己做一個插件來實現(xiàn)投稿功能。

首先新建submit_posts_ajax.php，將以下內(nèi)容復制進去：

<?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>發(fā)現(xiàn)重復文章.你已經(jīng)發(fā)表過了.或者存在該文章</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;

}

$info='<div class=post_submit_info>感謝: '.$author.' 的供稿.</div>'.nn;

if(isset($_post['post_submit'])){

//錯誤判斷

if($title==''){

echo '<div class=ps_errormsg>錯誤:沒有填寫標題!</div>';

die();

}

elseif($mail==''){

echo '<div class=ps_errormsg>錯誤:沒有填寫郵箱地址.</div>';

die();

}

elseif($content==''){

echo '<div class=ps_errormsg>錯誤:還沒有填寫內(nèi)容!!!</div>';

die();

}else{

//提交數(shù)據(jù)

$content=$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);

$subject='您給[ '.get_option('blogname').' ]寫了篇文章 標題是: '.$title;

$message='非常感謝您的供稿.您的稿件已經(jīng)提交.等待管理員的審核. 以下是您提交的內(nèi)容:<hr>'.stripslashes(trim($_post['post_content']));

yinheli_sendmail_ps($mail,$subject,$message);

echo '<div class=ps_msg>非常感謝您的供稿.您的稿件已經(jīng)提交.等待管理員的審核.請耐心等待.</div>';

@header('content-type: ' . get_option('html_type') . '; charset=' . get_option('blog_charset'));

die();

}

}

if(isset($_post['post_review'])){

if(''==$content){

echo '還沒有填寫內(nèi)容';

die();

}

if(''==$tags) $tags='您還沒有填寫 標簽 (tags)';

echo '<div class=ps_reviewmsg>

<h2>'.$title.'</h2>

<div class=ps_reviewcontent>

'.$info.$content.'

<p class=ps_reviewtags>標簽:'.$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');

?>

接下來新建submit_posts.php，同樣將以下內(nèi)容復制進去：

<script type=text/javascript>

<!--

//-->

</script><?php

function submit_posts_html(){

ob_end_clean();

ob_start();

?>

<div id=ps_msg>歡迎給我供稿</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']);?>/> 投稿標題(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'];?> /> 您的名字或昵稱</label>

</div>

<div class=row>

<label><input type=text name=your_email id=your_email tabindex=3 value=<?php echo $_post['your_email'];?> /> 您的郵箱(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'];?> /> 您的網(wǎng)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']);?> /> 標簽(tags)[每個標簽用半角的逗號分開]</label>

</div>

<div id=submit_post>

<input type=submit name=post_review id=post_review value=預覽 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，將以下內(nèi)容復制進去：

/*

*/

(function(){

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

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){

var a=formtorequeststring($('post_submit_form'))+'&'+encodeuricomponent($(type).name)+'='+encodeuricomponent($(type).value);

return a;

}

function ps_submit(action){

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){

}

if (document.addeventlistener) {

}

})();

把以上三個文件保存在submit_posts文件夾內(nèi)，上傳至插件目錄，并進后臺安裝該插件。使用時只需要新建頁面并輸入[submit_posts]即可調(diào)用出。
