I have fixed the problem finaly @Barand thanks for the help as well function get_cat($cat_id = null) { $cat_id = (int)$cat_id; $sql = "SELECT `blog`.`post_id` AS `id` , `blog`.`post_title` AS `title`, `post_body` AS `body`, `blog_categories`.`id` AS `blog_category_id` FROM `blog` INNER JOIN `blog_categories` ON `blog_categories`.`id` = `blog`.`cat_id` WHERE `cat_id` = " . mysql_real_escape_string($_GET['id']); $cat = mysql_query($sql); $return = array(); while (($row = mysql_fetch_assoc($cat)) ) { $return[] = $row; } return $return; }

When I run this in phpmyadmin I get this SELECT `blog`.`post_id` AS `id` , `blog`.`post_title` AS `title` , `post_body` AS `body` , `blog_categories`.`id` AS `blog_category_id` FROM `blog` INNER JOIN `blog_categories` ON `blog_categories`.`id` = `blog`.`cat_id` WHERE `blog_categories`.`id` = '1'

Oke as u can see in the tables in the post what I have posted before What I am trying to do is I have made categories as u can see in this image . but here is the problem what I have when I click on the that category other categories are showing up as well See this image What Iam trying to do is that on category page only post are showing up what hav e been posted in that category As u can see now that is not working at this moment .

This is what I have done but still it dont works When I click category.php?id=4 it still show me other categories on that page as well function cat_id($cat_id) { $posts = array(); $query = "SELECT `blog_categories`.`id` AS `blog_category_id` FROM `blog` INNER JOIN `blog_categories` ON `blog_categories`.`id` = `blog`.`cat_id`"; if ( isset($cat_id)) { $cat_id = (int) $cat_id; $query .= " WHERE `blog_categories`.`id` = $cat_id"; } $query = mysql_query($query); while ( $row = mysql_fetch_assoc($query) ) { $posts[] = $row; } return $posts; }
