1- Why this function not shown at bottom of content ?
2- Why when we used this filter at top of content it's show review box at
summary of content at category page !!
1- Why this function not shown at bottom of content ?
Your filter must return content, not echo content, but you call sandy_reviews() inside the filter callback and sandy_reviews() prints content when it runs. You need to rewrite that function to return content instead of echo it.
2- Why when we used this filter at top of content it's show review box at
summary of content at category page !!
Your category archive is using the_content() to display the summaries and your code does nothing to prevent that. You want something like:
add_filter( 'the_content', 'sandy_posts_filter' );
function sandy_posts_filter( $content )
{
if (!is_single()) return $content;
// the rest of your code
Based on your question, you can add a filter to the_content to add custom content before or after the actual content. This will give you a headstart.
function wepse208756_filter_the_content( $content ) {
$customcontent = 'My Custom Content';
if ( isset($myvar) && $myvar == 'top' ) { //Adds Before The Content
$content = $customcontent . $content;
} elseif ( isset($myvar) && $myvar == 'bottom' ) { //Adds After The Content
$content = $content . $customcontent;
}
return $content;
}
add_filter( 'the_content', 'wepse208756_filter_the_content' );
Filter hook should return code not echo or print. You can use the_content filter
add_filter( 'the_content', 'my_the_content_filter', 20 );
/**
* Filtering The Content.
*/
function my_the_content_filter( $content ) {
$after = "<div>After div box</div>";
$before = "<div>Before div box</div>";
$content = $after . $content . $before;
// Returns the content.
return $content;
}
