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(gè)投稿頁面，當(dāng)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(gè)插件來實(shí)現(xiàn)投稿功能。

首先新建submit_posts_ajax.php，將以下內(nèi)容復(fù)制進(jìn)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(fù)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(cuò)誤判斷

if($title==''){

echo '<div class="ps_errormsg">錯(cuò)誤:沒有填寫標(biāo)題!</div>';

die();

}

elseif($mail==''){

echo '<div class="ps_errormsg">錯(cuò)誤:沒有填寫郵箱地址.</div>';

die();

}

elseif($content==''){

echo '<div class="ps_errormsg">錯(cuò)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);

$subject='您給[ '.get_option('blogname').' ]寫了篇文章 標(biāo)題是: '.$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(biāo)簽 (Tags)';

echo '<div class="ps_reviewmsg">

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

<div class="ps_reviewcontent">

'.$info.$content.'

<p class="ps_reviewtags">標(biāo)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";

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

?>

接下來新建submit_posts.php，同樣將以下內(nèi)容復(fù)制進(jìn)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(biāo)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(biāo)簽(tags)[每個(gè)標(biāo)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(yù)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(fù)制進(jìn)去：

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