正则表达式从[shortcode]中提取变量 [英] Regex extract variables from [shortcode]

问题描述

字符串内容：

/ p>

不相关的tekst ...
[sublimevideo class =sublime
poster =http：// video。 host.com/_previews/600x450/sbx-60025-00-da-ANA.png
src1 =http://video.host.com/_video/H.264/LO/sbx-60025-00 -da-ANA.m4v
src2 =（hd） http://video.host.com/_video/H.264/HI/sbx-60025-00-da-ANA.m4v
width =560 height =315]
.. more不相关的文本。

我需要找到所有的变量， sublimevideo ...]并将其转换成数组：

  Array（
 class =>sublime
 poster =>http://video.host.com/_previews/600x450/sbx-60025-00-da-FMT.png
 src1 =>http://video.host的.com / _视频/ H.264 / LO / SBX-60 025-00-da-FMT.m4v
 src2 => （hd）http://video.host.com/_video/H.264/HI/sbx-60025-00-da-FMT.m4v
 width => 560
 height => 315
）
  

最好处理短码的多个实例。

我想可以用preg_match_all（）完成，但我没有运气。

这将给你你想要的。

  $ data ='不相关的tekst ... [sublimevideo class =sublimeposter =http://video.host .com / _previews / 600x450 / sbx-60025-00-da-ANA.pngsrc1 =http://video.host.com/_video/H.264/LO/sbx-60025-00-da-ANA。 m4vsrc2 =（hd）http://video.host.com/_video/H.264/HI/sbx-60025-00-da-ANA.m4vwidth =560height =315]。更不相关的文字。 
 
 $ dat = array（）; 
 preg_match（/ \ [sublimevideo（。+？）\] /，$ data，$ dat）; 
 
 $ dat = array_pop（$ dat）; 
 $ dat = explode（，$ dat）; 
 $ params = array（）; 
 foreach（$ dat as $ d）{
 list（$ opt，$ val）= explode（=，$ d）; 
 $ params [$ opt] = trim（$ val，'''）; 
} 
 
 print_r（$ params）; 
  

预计您将处理短代码时遇到的下一个挑战，您可以使用preg_replace_callback替换短标签数据及其结果标记。

  $ data ='不相关tekst ... [sublimevideo class =sublimeposter =http://video.host.com/ _previews / 600x450 / sbx-60025-00-da-ANA.pngsrc1 =http://video.host.com/_video/H.264/LO/sbx-60025-00-da-ANA.m4vsrc2 =（hd）http://video.host.com/_video/H.264/HI/sbx-60025-00-da-ANA.m4vwidth =560height =315] ..更不相关文本'; 
 
函数processShortCode（$ matches）{
 //解析参数
 $ dat = explode（，$ matches [2]）; 
 $ params = array（）; 
 foreach（$ dat as $ d）{
 list（$ opt，$ val）= explode（=，$ d）; 
 $ params [$ opt] = trim（$ val，''）; 
} 
 switch（$ matches [1]）{
 casesublimevideo：
 //这里是要从shorttag调用返回结果标记的地方。 
 return print_r（$ params，true）; 
} 
 
} 
 $ data = preg_replace_callback（/ \ [（\w +）（。+？）] /，processShortCode，$ data）; 
 echo $ data; 
  

After migrating some content from WordPress to Drupal, I've got som shortcodes that I need to convert:

String content:

Irrelevant tekst... [sublimevideo class="sublime" poster="http://video.host.com/_previews/600x450/sbx-60025-00-da-ANA.png" src1="http://video.host.com/_video/H.264/LO/sbx-60025-00-da-ANA.m4v" src2="(hd)http://video.host.com/_video/H.264/HI/sbx-60025-00-da-ANA.m4v" width="560" height="315"] ..more irrelevant text.

I need to find all variables within the shortcode [sublimevideo ...] and turn it into an array:

Array (
    class => "sublime"
    poster => "http://video.host.com/_previews/600x450/sbx-60025-00-da-FMT.png"
    src1 => "http://video.host.com/_video/H.264/LO/sbx-60025-00-da-FMT.m4v"
    src2 => "(hd)http://video.host.com/_video/H.264/HI/sbx-60025-00-da-FMT.m4v"
    width => "560"
    height => "315"
)

And preferably handle multiple instances of the shortcode.

I guess it can be done with preg_match_all() but I've had no luck.

解决方案

This will give you what you want.

$data = 'Irrelevant tekst... [sublimevideo class="sublime" poster="http://video.host.com/_previews/600x450/sbx-60025-00-da-ANA.png" src1="http://video.host.com/_video/H.264/LO/sbx-60025-00-da-ANA.m4v" src2="(hd)http://video.host.com/_video/H.264/HI/sbx-60025-00-da-ANA.m4v" width="560" height="315"] ..more irrelevant text.';

$dat = array();
preg_match("/\[sublimevideo (.+?)\]/", $data, $dat);

$dat = array_pop($dat);
$dat= explode(" ", $dat);
$params = array();
foreach ($dat as $d){
    list($opt, $val) = explode("=", $d);
    $params[$opt] = trim($val, '"');
}

print_r($params);

In anticipation of the next challenge you will face with processing short codes you can use preg_replace_callback to replace the short tag data with it's resultant markup.

$data = 'Irrelevant tekst... [sublimevideo class="sublime" poster="http://video.host.com/_previews/600x450/sbx-60025-00-da-ANA.png" src1="http://video.host.com/_video/H.264/LO/sbx-60025-00-da-ANA.m4v" src2="(hd)http://video.host.com/_video/H.264/HI/sbx-60025-00-da-ANA.m4v" width="560" height="315"] ..more irrelevant text.';

function processShortCode($matches){
    // parse out the arguments
    $dat= explode(" ", $matches[2]);
    $params = array();
    foreach ($dat as $d){
        list($opt, $val) = explode("=", $d);
        $params[$opt] = trim($val, '"');
    }
    switch($matches[1]){
        case "sublimevideo":
            // here is where you would want to return the resultant markup from the shorttag call.
             return print_r($params, true);        
    }

}
$data = preg_replace_callback("/\[(\w+) (.+?)]/", "processShortCode", $data);
echo $data;
