To get post info outside the regular loop, you can use WP Query Reference In your example you can try something like; $firstsentance = new WP_Query(); $firstsentance->query(‘posts_per_page=-1′); // add additional query parameters as needed, this will query all posts $old_content = the_content()’; //do your php stuff here endwhile;
If you’re using WP_Query, then assign that page a custom meta key ‘home_content’ with a value as 1. Then use WP_Query’s custom field parameters to loop over it. If you can restrict the title as ‘About’ everywhere, use get_page_by_title, and if you can restrict the slug as ‘about’, use get_page_by_path. These methods will work dynamically.
I am not aware of a dedicated action, but you could prevent double processing with an internal cache in your function. Pseudo code: function content_filter( $content ) { static $cache = array(); $id = get_the_ID(); if ( in_array( $id, $cache ) ) { return $content; // we did this already } $cache[] = $id; return … Read more
That’s because you overrule the query. You have to put the original info into the query_posts like so: <?php global $query_string; query_posts($query_string . ‘posts_per_page=10&paged=’.$paged); ?> For more info look here: http://codex.wordpress.org/Function_Reference/query_posts#Usage_Note
You should not use query_posts more than one time. It will create errors. You have to use wp_query. Here is what it says in wordpress codex: query_posts( is meant for altering the main loop. Once you use query_posts(), your post-related global variables and template tags will be altered. Conditional tags that are called after you … Read more
You can use the has_tag function in a conditional statement to achieve what you want. Take a look at the codex page here: Function Reference/has tag. This isn’t 100% tailored to your specific question, but you should see how it’s working and adjust for your specific task: <?php if( has_tag() ) { ?> <?php query_posts( … Read more
In general I try to avoid custom SQL queries as much as i can and use the native WordPress functions but in some cases its much better/faster to use custom queries. if the case is just get a list of posts the you can use the WP_Query or get_posts which will work almost as fast … Read more
Just before the snippet i posted i was doing something like $posts = array();, it seems that wordpress keeps the collection of the posts to be used on the loop in a variable of the same name, so i was meesing with the data, just changed $posts for $items and now works fine.
Figured it out. Just need to add $post_id to the template tag like so. if (in_category(‘videos’,$post_id)) {
After researching this, here is what works for me: <?php $paragraphAfter= 1; //show box after selected paragraph $content = apply_filters(‘the_content’, get_the_content()); $content = explode(“</p>”, $content); for ($i = 0; $i <count($content); $i++) { if ($i == $paragraphAfter) { ?> <!– START OF BLOCKQUOTE –> stuff <!– END OF BLOCKQUOTE –> <?php } echo $content[$i] . … Read more
