Consider this an example:<\/p>\n

First you have to extract those values using PHP. After the extraction, you can now present it on HTML. You can use a dropdown box (here in this example), to select which category you want to see.<\/p>\n

index.php<\/strong><\/p>\n

<?php\n\n\/\/ use $_GET variable for your query\n$category = (isset($_GET['category']) && $_GET['category'] != '') ? (int) $_GET['category'] : null;\n\n\/\/ connect to mysql\n$con = mysqli_connect(\"localhost\",\"user\",\"password\",\"database\");\n\n\/\/ build your query\n$query_statement=\"SELECT `listing`.`id`, `listing`.`cat_id`, `category`.`category`, `listing`.`title`, `listing`.`author` FROM `listing` LEFT JOIN `category` ON `listing`.`cat_id` = `category`.`cat_id`\";\nif($category != null) {\n    $query_statement = $query_statement . \" WHERE `category`.`cat_id` = $category\";\n}\n\n$query = mysqli_query($con, $query_statement);\n\n?>\n\n<!-- HTML -->\n<!-- Loop them inside a table -->\n<form method=\"GET\" action=\"index.php\">\n    <select name=\"category\" onchange=\"this.form.submit()\">\n        <option disabled selected>Select Category<\/option>\n        <option value=\"\">All<\/option>\n        <option value=\"1\">Art<\/option>\n        <option value=\"2\">Drama<\/option>\n        <option value=\"3\">Music<\/option>\n        <option value=\"4\">Fiction<\/option>\n        <option value=\"5\">Computer<\/option>\n    <\/select>\n<\/form>\n\n<table border=\"1\" cellpadding=\"10\">\n    <thead>\n        <tr>\n            <th>Category<\/th>\n            <th>Title<\/th>\n            <th>Author<\/th>\n        <\/tr>\n    <\/thead>\n    <tbody>\n    <?php while($result = mysqli_fetch_assoc($query)): ?>\n        <tr>\n            <td><?php echo $result['category']; ?><\/td>\n            <td><?php echo $result['title']; ?><\/td>\n            <td><?php echo $result['author']; ?><\/td>\n        <\/tr>\n    <?php endwhile; ?>\n    <\/tbody>\n<\/table>\n<\/code><\/pre>\n
EDIT:<\/p>\n
<!-- LINKS (if you need links you can do something like this) -->\n<a href=\"https:\/\/stackoverflow.com\/questions\/23334349\/index.php?category=1\">Art<\/a>\n<a href=\"index.php?category=2\">Drama<\/a>\n<a href=\"index.php?category=3\">Music<\/a>\n<a href=\"index.php?category=4\">Fiction<\/a>\n<a href=\"index.php?category=5\">Computer<\/a>\n<\/code><\/pre>\n
\n
Note: Try to study more of these and then try to enhance some of its parts, like security<\/strong>, etc. Just use this as a stepping stone towards learning more since you did not posted any code related to the problem.<\/em><\/p>\n<\/blockquote><\/div>\n
