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;
    $ps_sendmail_headers .= content-type: text/html;charset=$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 $submit_posts_html;
    }
    add_shortcode('submit_posts','submit_posts_display');
    ?>
    接下來新建submit_posts.php，同樣將以下內(nèi)容復(fù)制進(jìn)去：
    <script type=text/javascript>
    <!--
    //-->
    </script><?php
    function submit_posts_html(){
    ob_end_clean();
    ob_start();
    ?>
    <div id=ps_msg>歡迎給我供稿</div>
    <form id=post_submit_form name=post_submit_form method=post action=>
    <div class=row>
    <input type=hidden name=submit_posts_ajax id=submit_posts_ajax value=yinheli/>
    <label><input type=text name=post_title id=post_title tabindex=1 value=<?php echo strip_tags($_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：
    /*
    author: 89948
    update: 2009/04/11
    author uri:

    (function(){

    function setstyle(element, key, value) {

    if(!(referencenode = $(referencenode))) return false;
    return referencenode.parentnode.insertbefore(node, referencenode.nextsibling);
    };
    function preventdefault(eventobject) {

    setopacity(the_form,0.8);

    alert('呃 出錯(cuò)了 (建議您保存好文章再刷新瀏覽器.) 錯(cuò)誤信息:'+xmlhttp.statustext);

    function submitactiontype(type){

    }
    function ps_submit(action){

    var url=window.location.href;

    }, 10);
    } else {
    window.onload = function(e) {
    initps();
    }
    }
    })();
    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。
