• 为Joomla 2.5的连续插入多幅图像添加便捷方式


    用过Joomla 2.5的朋友应该都知道插入很多图像时是比較麻烦的。点了文章以下的图片button,它会弹出个div,让你选择图片,每选一张。div就关闭。

    再选第二张的时候,它又要你又一次选择文件夹。对于我常常要一次插入10张图片以上的非常麻烦。

    (这里借用官网的图片。以下把这里叫sbox)


    当然了,这是Joomla自带的插入图片的快捷button。我用的TinyMCE的图片插入更朴素:



    我一直在找一种便于插入图片的方法。

    本来是想升级editor到TinyMCE 4的,但是我的Joomla是Synology自带的应用。跟官方的Joomla不太一样,升级不了。

    想用JCE 2.6,安装之后死活出不来编辑器的界面,查了一下好多人也有这问题。并且能一边预览一边插入的好像也不多。


    仅仅好自己动手了,

    1. 思路:

    在点击“图片”button后将TinyMCE editor中的文章的HTML源代码载入到sbox中,然后一边浏览图片一边将图片地址插入到文章的HTML源代码中,这个过程中sbox的div窗体不关闭。

    等终于图片插入完成后,点一个自己添加的button,将文章返回给TinyMCE editor。同一时候关闭窗体。

    2. 草案:

    须要添加一个textarea。来放置文章的源码。一个button。title="OK",用来在完毕后返回文章编辑界面。

    同一时候要改动自带的Insert的行为。

    3. 代码:

    a. joomla->administrator->components->com_media->views->images->tmpl->default.php的终于代码。(这里相应图片选择器)

    >" /> </fieldset> </form> <?php endif; ?>

    上面我添加的部分都用//added by henry和//ended by henry包围了起来。


    b. 由于添加了一个textarea。所以原先整个sbox的高度也要适当添加:

    在joomla->plugins->editors-xtd->image->image.php的倒数第8行左右。找到这句:

    $button->set('options', "{handler: 'iframe', size: {x: 800, y: 500}}");
    改成

    $button->set('options', "{handler: 'iframe', size: {x: 800, y: 700}}");

    700的高度适应性挺好的。


    终于的效果:

    一边看着图片一边点击“Insert”插入到HTML代码中:


    插入完成之后,点击“OK”,将HTML源码返回tiny mce编辑器。


    感觉还不错,写多图文章不再是恶梦。

    希望本文让Joomla的用户插入图片时更舒服些。
