Question:
For some reason my search script will only display the first set of results for the first page but when I click on the pagination link to the next page the results that are generated from the search script will not be displayed how can I correct this problem?
Here is my PHP & MySQL pagination code.
$x = ''; $construct = ''; if(isset($_POST['search'])) { $search = $_POST['search']; if(strlen($search) <= 2){ echo ''; } else { $mysqli = mysqli_connect("localhost", "root", "", "sitename"); mysqli_select_db($mysqli, "sitename"); $search_explode = explode(" ", $search); foreach($search_explode as $search_each) { $x++; if($x == 1){ $construct .= " article_content LIKE '%$search_each%' OR title LIKE '%$search_each%' OR summary LIKE '%$search_each%'"; } else { $construct .= " OR article_content LIKE '%$search_each%' OR title LIKE '%$search_each%' OR summary LIKE '%$search_each%'"; } } $construct = "SELECT users.*, users_articles.* FROM users_articles INNER JOIN users ON users_articles.user_id = users.user_id WHERE $construct"; $run = mysqli_query($mysqli, $construct); $search_term = mysqli_num_rows($run); } } // Number of records to show per page: $display = 10; // Determine how many pages there are... if (isset($_GET['p']) && is_numeric($_GET['p'])) { // Already been determined. $pages = mysqli_real_escape_string($mysqli, htmlentities(strip_tags($_GET['p']))); } else { // Need to determine. // Count the number of records: $records = $search_term; // Calculate the number of pages... if ($records > $display) { // More than 1 page. $pages = ceil ($records/$display); } else { $pages = 1; } } // End of p IF. // Determine where in the database to start returning results... if (isset($_GET['s']) && is_numeric($_GET['s'])) { $start = mysqli_real_escape_string($mysqli, htmlentities(strip_tags($_GET['s']))); } else { $start = 0; } // Make the links to other pages, if necessary. if ($pages > 1) { // Add some spacing and start a paragraph: echo '<p>'; // Determine what page the script is on: $current_page = ($start/$display) + 1; //add this here... first will always be one if ($current_page != 1) { echo '<a href="search.php">First</a>'; } // If it's not the first page, make a Previous button: if ($current_page != 1) { echo '<a href="search.php?s=' . ($start - $display) . '&p=' . $pages . '">Previous</a> '; } //create the links for ($i = max(1, $current_page - 3); $i <= min($current_page + 3, $pages); $i ++) { if ($i != $current_page) { echo '<a href="search.php?s=' . (($display * ($i - 1))) . '&p=' . $pages . '">' . $i . '</a> '; } else { echo '<span>' . $i . '</span> '; } } // If it's not the last page, make a Next button: if ($current_page != $pages) { echo '<a href="search.php?s=' . ($start + $display) . '&p=' . $pages . '">Next</a>'; } //add this here... Last will always be one if ($current_page != $pages) { echo '<a href="search.php?s=' . ($display * ($pages - 1)) . '&p=' . $pages . '">Last</a>'; } echo '</p>'; // Close the paragraph. } // End of links section. Here is the part of PHP & MySQL search code.
$x = ''; $construct = ''; if(isset($_POST['search'])) { $search = $_POST['search']; if(strlen($search) <= 2){ echo 'Your search term is too short!'; } else { $mysqli = mysqli_connect("localhost", "root", "", "sitename"); mysqli_select_db($mysqli, "sitename"); $search_explode = explode(" ", $search); foreach($search_explode as $search_each) { $x++; if($x == 1){ $construct .= " article_content LIKE '%$search_each%' OR title LIKE '%$search_each%' OR summary LIKE '%$search_each%'"; } else { $construct .= " OR article_content LIKE '%$search_each%' OR title LIKE '%$search_each%' OR summary LIKE '%$search_each%'"; } } $construct = "SELECT users.*, users_articles.* FROM users_articles INNER JOIN users ON users_articles.user_id = users.user_id WHERE $construct"; $construct .= " LIMIT $start, $display"; $run = mysqli_query($mysqli, $construct); $foundnum = mysqli_num_rows($run); if ($foundnum == 0) { echo 'Search term is too short!</p>No results found.'; } else { echo 'results'; } } }
Solution:1
That's a lot of code to look through, but could I hazard a guess that $_POST['search'] isn't set when you click on a pagination link, thus causing your entire second block of code not to be run?
Solution:2
Use Session . Below I show you an example of how to do it.
$number = $_POST['studentid']; if (empty($number)) { $number=$_SESSION['number']; } else{$number=$number ; ) //take a look At the top of the page put - <? session_start(); ?>
Put the following just before the script for navigation (Next Page/Previous Page)
$_SESSION['number']=$number; $_COOKIE['number'] = $number; Note:If u also have question or solution just comment us below or mail us on toontricks1994@gmail.com
