为了实现自动化，而不是像这样列出一长串代码

<td valign="top"width="50%"><p><label for="Facebook"><strong>Facebook URL</strong></label><input  type="text" name="Facebook" id="Facebook" size="52" value="<?php echo get_option(\'Facebook_url\'); ?>"/></p></td></tr><tr>

我想从PHP中回显所有这些内容以生成页面。我已经构建了一个包含所有社交网络、推特/脸书等的数组。截至目前，它可以读取保存的设置，但不允许保存新的输入。

function display_settings_fields($value,$key){
$keyurl = $key.\'_url\';
echo "The key $key has the value $value<br />";
echo \'<td valign="top"width="50%"><p><label for="\'.$key.\'"><strong>\'.$key .\'URL</strong></label><input  type="text" name="\'.$key.\'" id="\'.$key.\'" size="52" value="\';
echo get_option(\'\'.$keyurl.\'\');
echo \'"/></p></td></tr><tr>\';

    }
    $social_icon_set = array(
    "Twitter" =>"$twitter_url",
    "Facebook" =>"$facebook_url",
    "GooglePlus" =>"$googleplus_url",
    "Yelp" =>"$yelp_url",
    "Youtube" =>"$youtube_url",
    "Vimeo" =>"$vimeo_url",
    "Flickr" =>"$flickr_url",
    "Tumblr" =>"$tumblr_url",
    "Picplz" =>"$picplz_url",
    "Foursquare" =>"$foursquare_url",
    "RSS" =>"$rss_url",
    "Behance" =>"$behance_url",
    "Goodreads" =>"$goodreads_url",
    "Github" =>"$github_url",
    "Formspring" =>"$formspring_url",
    "Myspace" =>"$mypsace_url",
    "Klout" =>"$klout_url",
    "Diaspora" =>"$diaspora_url",
    "LinkedIn" =>"$linkedin_url"
    );
    array_walk($social_icon_set,"display_settings_fields");
    ?>

“echo get\\u选项（\'.$keyurl.\'）；”会出现问题。现在，它会回显正确的值，即为其保存的值，但它不允许保存在文本字段中编辑的任何内容。这甚至可以在其可保存的位置回显/打印出来吗。

（这主要是PHP，但如果有其他解决方法，因为它使用wordpress的get\\u选项，我愿意接受这些想法）
