Hello.
We use for ages now a small code provided by the support guys, that each attachment that was a photo, was show inline (embeded) to the body. Worked perfectly well.
Now it seems something changed, and if I EDIT such a post, the image becomes attachment after saving.
Any ideas how to fix this?
Thanks

The code is:
add_filter('wpforo_content_after', 'wpforo_default_attachment_image_embed', 11);
function wpforo_default_attachment_image_embed($content)
{
if (preg_match_all('|<a class=\"wpforo\-default\-attachment\" href\=\"([^\"\']+)\"[^><]*>.+?<\/a>|is', $content, $data, PREG_SET_ORDER)) {
foreach ($data as $array) {
if (isset($array[1])) {
$file = $array[1];
$e = strtolower(substr(strrchr($file, '.'), 1));
if ($e == 'jpg' || $e == 'jpeg' || $e == 'png' || $e == 'gif') {
$filename = explode('/', $file);
$filename = end($filename);
$html = '<a href="' . esc_url($file) . '" target="_blank"><img class="wpforo-default-image-attachment" src="' . esc_url($file) . '" alt="' . esc_attr($filename) . '" title="' . esc_attr($filename) . '" /></a>';
$content = str_replace($array[0], $html, $content);
}
}
}
}
return $content;
}

Hi @dimalifragis,
Delete the old Code and add the new one:
add_filter('wpforo_content_after', function( $content ){
return preg_replace_callback(
'#<a[^><]*\sclass=[\'\"](?:[^\'\"]*\s)?wpforo-default-attachment(?:\s[^\'\"]*)?[\'\"][^><]*\shref=[\'\"]([^\"\']+)[\'\"][^><]*>.*?</a>#isu',
function( $match ){
$html = $match[0];
$file = $match[1];
$pathinfo = pathinfo( $file );
if( wpforo_is_image($pathinfo['extension']) ) {
$html = sprintf(
'<a href="%1$s" target="_blank"><img class="wpforo-default-image-attachment" src="%1$s" alt="%2$s" title="%2$s"></a>',
esc_url($file),
esc_attr($pathinfo['basename'])
);
}
return $html;
},
$content
);
}, 11);

Copy and paste the Code again, please. We have updated in my above reply.
