短代码有问题。。我可能不知道在哪里&；如何设置条件，以便根据toturial的主题/类别显示正确的图像。。

帮助Plz：）

function postInfoBoxSc( $atts ) {
    extract( shortcode_atts( array(
        \'subject\' => \'Category type\',
        \'difficulty\' => \'User Types\',
        \'completiontime\' => \'completion Time\'
    ), $atts ) );

        // Set image acorring to guide type
        if ($subject == \'wordpress\') {
            $subjectImg = \'<img src="\'.get_bloginfo(\'template_url\').\'/img/postInfoBox/wordpress.png" alt="מדריך וורדפרס" />\';
        } elseif ($subject == \'web design\') {
            $subjectImg = \'<img src="\'.get_bloginfo(\'template_url\').\'/img/postInfoBox/webDesign.png" alt="מדריך בניית אתרים" />\';
        } elseif ($subject == \'facebook\') {
            $subjectImg = \'<img src="\'.get_bloginfo(\'template_url\').\'/img/postInfoBox/facebook.png" alt="מדריך פייסבוק" />\';
        } elseif ($subject == \'RSS\') {
            $subjectImg = \'<img src="\'.get_bloginfo(\'template_url\').\'/img/postInfoBox/rss.png" alt="מדריך RSS" />\';
        }

    return \'
    <br class="clear" />
    <div class="postInfoBox">
        \'. $subjectImg .\'
        <h5>Guide information:</h5>
        <ul>
            <li><strong>Category:</strong> \'. $subject .\'</li>

                    <li><strong>User Lever:</strong> \'. $difficulty .\'</li>

                    <li><strong>completion Time:</strong> \'. $completiontime .\'</li>

        </ul>
    </div>
    \';
}
add_shortcode( \'postInfoBox\', \'postInfoBoxSc\' );

The Problem出于某种原因，$subject的值不会像其他值一样更新，不会通过快捷码传递，图像也不会因此而改变

What Am I Doing Wrong ??

（仅根据请求添加）这是我在wordpress编辑器中写帖子时需要输入的短代码：

[postInfoBox subject="somthing" difficulty="hard" completiontime="2-5 minuts"]

    // Set image acorring to guide type
    if ($subject == \'wordpress\') {
        $subjectImg = \'<img src="\'.get_bloginfo(\'template_url\').\'/img/postInfoBox/wordpress.png" alt="מדריך וורדפרס" />\';
    } elseif ($subject == \'web design\') {
        $subjectImg = \'<img src="\'.get_bloginfo(\'template_url\').\'/img/postInfoBox/webDesign.png" alt="מדריך בניית אתרים" />\';
    } elseif ($subject == \'facebook\') {
        $subjectImg = \'<img src="\'.get_bloginfo(\'template_url\').\'/img/postInfoBox/facebook.png" alt="מדריך פייסבוק" />\';
    } elseif ($subject == \'RSS\') {
        $subjectImg = \'<img src="\'.get_bloginfo(\'template_url\').\'/img/postInfoBox/rss.png" alt="מדריך RSS" />\';
    } else {
        // Add default case
        $subject = "Default here";
        $subjectImg = \'<img src="\'.get_bloginfo(\'template_url\').\'/img/postInfoBox/default.png" alt="מדריך RSS" />\';
    }
