Yii framework extension to replace context of text with whatever you like.

Description and use cases ¶

You can use this extension to replaces 'standar' parts for a string to whatever you like. I will describe my personal use case. In my blog I used to add posts with title like:

• {yii}{ext} EReadmore
• {yii}{wiki} A simple...
• {php} New to ...

This was to categorize the Posts. So one day i wanted to replace all this with some icons. The code below does this work for me. Other use cases can be to display emoticons in text, tags, etc.

Code example ¶

Notice that there is not constrain to use a key=>value array as data. What $data will be depends entirely to you and its related to who you will access that data in the replace eval phrase.

$this->beginWidget('ext.EReplacer', array(
        'bag'=>'{}',
        'data'=>array(
           'yii'=>'http://image src...',
           'wiki'=>'http:///image src...',
           'php'=>'http://image src...',
        ),
        'replace'=>'"<img src=\'".$data[$el]."\' />";',
    ));
    echo $post->title;
    $this->endWidget();

You can as well use the text property like:

$this->widget('ext.EReplacer', array(
        'bag'=>'{}',
        'text'=>$post->title,
        'data'=>array(
           'yii'=>'http://image src...',
           'wiki'=>'http:///image src...',
           'php'=>'http://image src...',
        ),
        'replace'=>'"<img src=\'".$data[$el]."\' />";',
    ));
