如何從wordpress的tinymce編輯器獲取圖片？

Question

我有代碼顯示特色圖像顯示在帖子中，也知道獲取特色圖像路徑網址。但我不知道如何獲取插入tinymce圖像的url路徑。插入的圖像在帖子上正確顯示，但我不知道如何獲取圖像的相應網址。這是我使用的代碼。

function bdw_get_images() { 

    // Get the post ID 
    $iPostID = $post->ID; 

    // Get images for this post 
    $arrImages =& get_children('post_type=attachment&post_mime_type=image&post_parent=' . $iPostID); 

    // If images exist for this page 
    if($arrImages) { 

     // Get array keys representing attached image numbers 
     $arrKeys = array_keys($arrImages); 

     /******BEGIN BUBBLE SORT BY MENU ORDER************ 
     // Put all image objects into new array with standard numeric keys (new array only needed while we sort the keys) 
     foreach($arrImages as $oImage) { 
      $arrNewImages[] = $oImage; 
     } 

     // Bubble sort image object array by menu_order TODO: Turn this into std "sort-by" function in functions.php 
     for($i = 0; $i < sizeof($arrNewImages) - 1; $i++) { 
      for($j = 0; $j < sizeof($arrNewImages) - 1; $j++) { 
       if((int)$arrNewImages[$j]->menu_order > (int)$arrNewImages[$j + 1]->menu_order) { 
        $oTemp = $arrNewImages[$j]; 
        $arrNewImages[$j] = $arrNewImages[$j + 1]; 
        $arrNewImages[$j + 1] = $oTemp; 
       } 
      } 
     } 

     // Reset arrKeys array 
     $arrKeys = array(); 

     // Replace arrKeys with newly sorted object ids 
     foreach($arrNewImages as $oNewImage) { 
      $arrKeys[] = $oNewImage->ID; 
     } 
     ******END BUBBLE SORT BY MENU ORDER**************/ 

     // Get the first image attachment 
     $iNum = $arrKeys[0]; 

     // Get the thumbnail url for the attachment 
     $sThumbUrl = wp_get_attachment_thumb_url($iNum); 

     // UNCOMMENT THIS IF YOU WANT THE FULL SIZE IMAGE INSTEAD OF THE THUMBNAIL 
     //$sImageUrl = wp_get_attachment_url($iNum); 

     // Build the <img> string 
     $sImgString = '<a href="' . get_permalink() . '">' . 
          '<img src="' . $sThumbUrl . '" width="150" height="150" alt="Thumbnail Image" title="Thumbnail Image" />' . 
         '</a>'; 

     // Print the image 
     echo $sImgString; 
    } 
} 

任何一個給我的建議來獲取WordPress插入tinymce編輯器中的圖像url。

preg_match_all('/<img .*?(?=src)src=\"([^\"]+)\"/si', get_the_content(), $allpics); 
foreach($allpics[1] as $pics){ 
     echo $pics; 
} 

當您提取在WordPress循環後的內容，甚至通過get_post獲取，利用上述內容會給你所有存在於TinyMCE的編輯圖像的URL的發佈內容。

$post_details=get_post($post->ID); 
preg_match_all('/<img .*?(?=src)src=\"([^\"]+)\"/si', $post_details->post_content, $allpics); 
foreach($allpics[1] as $pics){ 
    echo $pics; 
}
