Create shortcode with parameter in PHP Joomla - php

Question

I've created a simple shortcode plugin on Joomla.
Actually I am trying to integrate Cleeng Video with Joomla. And will connect it's users in the future ( I hope ).
I've stack on creating shortcode's parameter. I don't know how to parse it's parameter and value.
My Shortcode is here (no parameter)
{cleengvideo}<iframe class="wistia_embed" src="http://fast.wistia.net/embed/iframe/5r8r9ib6di" name="wistia_embed" width="640" height="360" frameborder="0" scrolling="no" allowfullscreen=""></iframe>{/cleengvideo}
My code is here
public function onContentPrepare($content, $article, $params, $limit) {
preg_match_all('/{cleengvideo}(.*?){\/cleengvideo}/is', $article->text, $matches);
$i = 0;
foreach ($matches[0] as $match) {
$videoCode = $matches[1][$i];
$article->text = str_replace($match, $videoCode, $article->text);
}
I want to set height, width and 5r8r9ib6di this code from shortcode at least.
Please can anyone help me with adding and parsing it's parameter

Answer 1

To get a parameter, you can simply use the following code:
$params->get('param_name', 'default_value');
So for example, in your XML file, if you had a field like so:
<field name="width" type="text" label="Width" default="60px" />
you would call the parameter like so:
$params->get('width', '60px');
Note that you don't have to add the default value as the second string, however I always find it good practice.
Hope this helps

I think I could found it's solution.
It's here https://github.com/Cleeng/cleeng-wp-plugin/blob/master/php/classes/Frontend.php
Code is
$expr = '/\[cleeng_content(.*?[^\\\])\](.*?[^\\\])\[\/cleeng_content\]/is';
preg_match_all( $expr, $post->post_content, $m );
foreach ( $m[0] as $key => $content ) {
$paramLine = $m[1][$key];
$expr = '/(\w+)\s*=\s*(?:\"|")(.*?)(?<!\\\)(?:\"|")/si';
preg_match_all( $expr, $paramLine, $mm );
if ( ! isset( $mm[0] ) || ! count( $mm[0] ) ) {
continue;
}
$params = array( );
foreach ( $mm[1] as $key => $paramName ) {
$params[$paramName] = $mm[2][$key];
}
if ( ! isset( $params['id'] ) ) {
continue;
}
$content = array(
'contentId' => $params['id'],
'shortDescription' => #$params['description'],
'price' => #$params['price'],
'itemType' => 'article',
'purchased' => false,
'shortUrl' => '',
'referred' => false,
'referralProgramEnabled' => false,
'referralRate' => 0,
'rated' => false,
'publisherId' => '000000000',
'publisherName' => '',
'averageRating' => 4,
'canVote' => false,
'currencySymbol' => '',
'sync' => false
);
if ( isset( $params['referral'] ) ) {
$content['referralProgramEnabled'] = true;
$content['referralRate'] = $params['referral'];
}
if ( isset( $params['ls'] ) && isset( $params['le'] ) ) {
$content['hasLayerDates'] = true;
$content['layerStartDate'] = $params['ls'];
$content['layerEndDate'] = $params['le'];
}
$this->cleeng_content[$params['id']] = $content;
}

Hope this helps someone searching for shortcode parameters, for parameters in short code we can use preg_match_all like that
preg_match_all('/{cleengvideo(.*?)}(.*?){\/cleengvideo}/is', $article->text, $matches);
This will give a array with 3 array elements, the second array have the parameters which you can maupulate with codes.
Hope this helps.
