小编DCH*_*CHP的帖子

我有下面的代码.

$coauthors = get_post_meta( $post_id, "coAuthors" );

print_r($coauthors);

print_r的确定结果是

Array ( [0] => 78 ) Array ( [0] => 78 )

现在我的用户ID是78所以它应该使用以下代码返回true但它不是.

$key = array_search( 78, $coauthors );

     if($key) { 

     return true;

     }else{

     echo "no"; 

     }

为什么我总是得不到我错在哪里最好的办法是什么？

谢谢

我在这里仍然遇到问题是我的功能.

   add_action('is_true','isdAuthorTrue');

    function isdAuthorTrue( $post_id ) { 

        $current_user = wp_get_current_user();
    if ( !($current_user instanceof WP_User) )
    return;

        $current_user = wp_get_current_user();

         $coauthors = get_post_meta( $post_id, "coAuthors" );

         $key = array_search( $current_user->ID, $coauthors );
         $key = 0;
         if($key !== false) {

           return true;

         } …

我想在mac mini上安装gpg工具我有ssh访问权限,所以我可以安装s3cmd.

我知道你可以在这里使用安装程序dmg http://www.gpgtools.org/installer/index.html

但由于我只有ssh访问,我需要通过终端安装这个,并且无法找到在哪里这样做,如果我点击源它带我到这个页面https://github.com/GPGTools/GPGTools这对我没有帮助.

有人能指出我正确的方向.

我一直在rails上使用ruby没问题,现在突然每次我运行rake db:create我得到以下错误:

C:\>cd xampp

C:\xampp>cd htdocs

C:\xampp\htdocs>cd what

C:\xampp\htdocs\what>rake db:create
rake aborted!
undefined method `task' for #<What::Application:0x20eb1e0>

(See full trace by running task with --trace)

C:\xampp\htdocs\what>

有什么帮助吗???

这是我的所有cmd

有没有人有这个问题,当我从数据库中提取数据时,它看起来像下面,它在实际的数据库表中看起来很好.

我正在使用wordpress.任何建议都让我头疼.

这些是标签

我遇到了timthumb.php和colourbox灯箱的问题,timthumb在其他一切方面工作得很好但是当我尝试加载更大的图像时,我得到以下内容

图像只显示代码真的需要帮助???

这是我的代码.

if ($handle = opendir('./users/2/images')) {
    while (false !== ($entry = readdir($handle))) {


        if ($entry != "." && $entry != "..") {

            if(preg_match("/\.(png|gif|jpg|jpeg|JPG)$/i", $entry)) {

            $file = site_url() . "/users/2/images/$entry";

            $removeLink = "users/2/images/$entry";

          echo '<li><a class="group1" href="'.get_bloginfo('template_url').'/timthumb.php?src='.$file.'&h=500&q=80&webshot=1"><img src="'.get_bloginfo('template_url').'/timthumb.php?src='.$file.'&h=80&zc=1"  onload="this.style.visibility=\'visible\'" /></a><a href="'.$file.'" rel="nofollow">Download</a><a class="imageSort" href="" id="'.$removeLink.'" title="images">drag me</a><a href="'.$file.'" rel="nofollow">View Raw</a></li>';      

            } 
        } 
    }
    closedir($handle);

有谁有类似的问题???

碰到任何人得到和建议与这???
