help with custom php for thematic framework theme WordPress

Cristian Antohe answers:

Hi,

This is a different solution then Michael's. For this you don't need to have the plugin activated and it searches for the first link differently.

You can see it working here:
http://www.cozmoslabs.com/projects/nomadic/



// Search for first link function
function search_first_link($content){
$more = 1;
$count = substr_count($content, '<a');
$start = 0;
for($i=1;$i<=$count;$i++) {
$linkBeg = strpos($content, '<a', $start);
$post = substr($content, $linkBeg);
$linkEnd = strpos($post, '</a>');
$postOutput = substr($post, 0, $linkEnd+4);
$link[$i] = $postOutput;
$start=$linkEnd+1;
}
$more = 0;
if (!empty($link[1]))
{
return $link[1];
} else { return false; }
}

function extract_url_from_link($link){
$more = 1;
$count = substr_count($link, 'http://');
$start = 0;
for($i=1;$i<=$count;$i++) {
$urlBeg = strpos($link, 'http://', $start);
$post = substr($link, $urlBeg);
$urlEnd = strpos($post, '"');
$postOutput = substr($post, 0, $urlEnd);
$url[$i] = $postOutput;
$start=$linkEnd+1;
}
$more = 0;
if (!empty($url[1]))
{
return $url[1];
} else { return false; }
}

// Create the page title
function custom_title($the_title){
global $post;
$content = get_the_content();

$post_link = search_first_link($content);
if ($post_link)
{
return '<h2 class="entry-title">' . $post_link . '</h2>';
} else { return $the_title; }


}
add_filter('thematic_postheader_posttitle' ,'custom_title');

// Add the automatic image - With help from Ben Gillbanks - http://www.binarymoon.co.uk/
function bm_mshot ($url = '', $width = 250) {
if ($url != '') {
return 'http://s.wordpress.com/mshots/v1/' . urlencode(clean_url($url)) . '?w=' . $width;
} else {
return '';
}
}

function add_image_url($content){

$post_link = search_first_link($content);
$url = extract_url_from_link($post_link);
$imageUrl = bm_mshot ($url, 250);

if ($imageUrl == '') {
return $content;
} else {
$image = '<img src="' . $imageUrl . '" alt="' . $url . '" width="' . $width . '" />';
return '<div class="browsershot mshot"><a href="' . $url . '">' . $image . '</a></div>' . $content;
}
}

add_filter('the_content', 'add_image_url');
