帶有Open Graph標記的元標記助手

Question

如何使用Codeigniter元標記helper和Facebook開放圖元標記？

元標記助手希望注入名稱作爲Facebook不使用的第一個屬性。有什麼方法可以使用助手來添加我自己的自定義方案嗎？似乎有一些默認設置，例如'name'，我不能使用助手去除。

我做了什麼：

$meta = array(
     array('property' => 'og:type', 'content' => 'movie'), 
     array('property' => 'og:video:height', 'content' => '260'), 
     array('property' => 'og:video:width', 'content' => '420'), 
     array('property' => 'og:video:type', 'content' => 'application/x-shockwave-flash'), 
     array('property' => 'og:title', 'content' => $data['video']), 
     array('property' => 'og:description', 'content' => $data['video_desc']), 
     array('property' => 'og:image', 'content' => 'http://i2.ytimg.com/vi/'.$data['links']['extra_link_info']['original_key'].'/hqdefault.jpg'), 
     array('property' => 'og:video', 'content' => 'https://www.youtube.com/v/'.$data['links']['extra_link_info']['original_key'].'?version=3&autohide=1&autoplay=1') 
     ); 

我得到什麼：

<meta name="" content="movie" /> 

<meta name="" content="260" /> 

<meta name="" content="420" /> 

<meta name="" content="application/x-shockwave-flash" /> 

<meta name="" content="xxxxxxxx" /> 

<meta name="" content="xxxxxxxx" /> 

<meta name="" content="http://i2.ytimg.com/vi/xxxxxxxx/hqdefault.jpg" /> 

<meta name="" content="xxxxxxxx" /> 

我想要什麼：

<meta property="og:tyoe" content="movie" /> 

<meta property="og:video:height" content="260" /> 

<meta property="og:video:width" content="420" /> 

<meta property="og:video:type" content="application/x-shockwave-flash" /> 

<meta property="og:title" content="xxxxxxxx" /> 

<meta property="og:description" content="xxxxxxxx" /> 

<meta property="og:image" content="http://i2.ytimg.com/vi/xxxxxxxx/hqdefault.jpg" /> 

<meta property="og:video" content="xxxxxxxx" /> 

Answer 1

固定它：

擴展了HTML幫助程序並將所有name引用改爲property。

MY_html_helper

<?php 

/** 
* Generates meta tags from an array of key/values 
* 
* @access public 
* @param array 
* @return string 
*/ 
if (! function_exists('meta')) 
{ 
    function meta($property = '', $content = '', $type = 'property', $newline = "\n") 
    { 
     // Since we allow the data to be passes as a string, a simple array 
     // or a multidimensional one, we need to do a little prepping. 
     if (! is_array($property)) 
     { 
      $property = array(array('property' => $property, 'content' => $content, 'type' => $type, 'newline' => $newline)); 
     } 
     else 
     { 
      // Turn single array into multidimensional 
      if (isset($property['property'])) 
      { 
       $property = array($property); 
      } 
     } 

     $str = ''; 
     foreach ($property as $meta) 
     { 
      $type  = (! isset($meta['type']) OR $meta['type'] == 'property') ? 'property' : 'http-equiv'; 
      $property  = (! isset($meta['property']))  ? '' : $meta['property']; 
      $content = (! isset($meta['content'])) ? '' : $meta['content']; 
      $newline = (! isset($meta['newline'])) ? "\n" : $meta['newline']; 

      $str .= '<meta '.$type.'="'.$property.'" content="'.$content.'" />'.$newline; 
     } 

     return $str; 
    } 
} 

Answer 2

我用這個

MY_html_helper.php

if (!function_exists('meta')) { 

function meta($name = '', $content = '', $type = 'name', $newline = "\n") { 
    // Since we allow the data to be passes as a string, a simple array 
    // or a multidimensional one, we need to do a little prepping. 
    if (!is_array($name)) { 
     $name = array(array('name' => $name, 'content' => $content, 'type' => $type, 'newline' => $newline)); 
    } else { 
     // Turn single array into multidimensional 
     if (isset($name['name'])) { 
      $name = array($name); 
     } 
    } 

    $str = ''; 
    foreach ($name as $meta) { 
     if ((!isset($meta['type']) OR $meta['type'] == 'name')) { 
      $type = 'name'; 
     } else if ($meta['type'] == 'equiv') { 
      $type = 'http-equiv'; 
     } else { 
      $type = $meta['type']; 
     } 
     $name = (!isset($meta['name'])) ? '' : $meta['name']; 
     $content = (!isset($meta['content'])) ? '' : $meta['content']; 
     $newline = (!isset($meta['newline'])) ? "\n" : $meta['newline']; 

     $str .= '<meta ' . $type . '="' . $name . '" content="' . $content . '" />' . $newline; 
    } 

    return $str; 
} 

} 

用法：

$meta = array(
    array('name' => 'og:title', 'content' => 'my great title', 'type' => 'property') 
);
