How to get attribute for shortcode in wordpress? - php

Question

I have constructed a shortcode like this:
[myshortcode id="4"]content[/myshortcode]
with this:
<?php
function f_shortcode($atts, $content = null) {
$returned_string = '<div class="wrap">';
$returned_string .= '<div class="frame">'.$content.'</div>';
$returned_string .= '</div>';
return $returned_string;
}
add_shortcode('myshortcode', 'f_shortcode');
?>
What i need from my shortcode is to retrieve a record from option table in the database (i.e retrieve content based on the id given in the shortcode)
In the options table i have this:
a:1:{i:0;O:8:"stdClass":4:{s:2:"id";s:1:"4";s:9:"title";s:5:"test";s:11:"content";s:5:"test content";s:13:"shortcode";s:29:"[myshortcode id="4"][/myshortcode id="4"]";}}
So to retrieve the content i have added this peace of code to my function:
extract(shortcode_atts(array(
'id' => 'id'
), $atts));
if(get_option('results_options') && get_option('results_options') != ''){
$results = get_option('results_options');
foreach ($results as $result){
if($result->id == '{$id}'){
$content = $result->content;
continue;
}
}
}
In my table the content is there, but it doesnt display or it doesnt even be retrieved, Is there a problem with my code ?
