I am working on a little search engine in PHP & MySQL. Yesterday, I restyled (I did changes only at the HTML part, no php code was touched) the result page, after that I was unable to search for a term.
New code:
<?php
header( 'Cache-Control: no-store, no-cache, must-revalidate' );
header( 'Cache-Control: post-check=0, pre-check=0', false );
header( 'Pragma: no-cache' );
require_once("lucene.php");
?>
<?php
$row1 = [];
$row2 = [];
$search_word = false;
if(isset($_POST["submit"])) {
//edit this with your credentials
$con = mysqli_connect("localhost", "root", "pass", "db");
if(mysqli_connect_error()) echo "Connection Fail";
else {
$search_word = true;
$input = $_POST["s_input"];
// tokenize input
$tokens = tokenize($input);
//compute weight of every token
$token_weight = compute_weight($tokens, $con);
$sql1 = "SELECT *, match(description) against('". $input ."') as score FROM web where match(description) against('".$input."') order by score desc";
$sql2 = "SELECT *, match(description) against('". $input ."') as score FROM web where match(description) against('".$input."') order by score desc";
$result1 = mysqli_query($con, $sql1);
$result2 = mysqli_query($con, $sql2);
$sql3 = "SELECT * FROM web";
$numDocs = (mysqli_num_rows(mysqli_query($con, $sql3)));
$maxOverlap = sizeof($tokens);
$ctr2 = 0;
while($ctr2 != $maxOverlap){
//compute inverse_document_frequency of term
$sql3 = "SELECT *, match(description) against('".$tokens[$ctr2]."') FROM web where match(description) against('".$tokens[$ctr2]."')";
$docFreq = (mysqli_num_rows(mysqli_query($con, $sql3)));
$idf[$tokens[$ctr2]] = idf($numDocs, $docFreq);
$ctr2++;
}
$ctr = 0;
while($r1 = mysqli_fetch_array($result1)){
$row1[$ctr]['ID'] = $r1['ID'];
$row1[$ctr]['title'] = $r1['title'];
$row1[$ctr]['description'] = highlight_words($r1['description'], $tokens);
$row1[$ctr]['credit'] = $r1['credit'];

$lucene_score = $summation * $coord * $queryNorm;
$row1[$ctr]['score'] = $lucene_score;
$ctr++;
}
$row1 = orderBy($row1);
/*
desc score = number of word ocurrences * weight + match_against weight
+ 2(if exact words occur)
*/
$ctr = 0;
while($r2 = mysqli_fetch_array($result2)){
$row2[$ctr]['ID'] = $r2['ID'];
$row2[$ctr]['title'] = $r2['title'];
$row2[$ctr]['description'] = highlight_words($r2['description'], $tokens);

I personally thinks that bug is somewhere in this section of code, but I can't figure out where it should be. Can someone look at it, and maybe lend me a hand ?

Before updates of server page was working fine.
Like written in the title my code works okay except for the quantity for the first product when there are multiple products, where you can remove by clicking update but cant change the quantity.

This is my cart.php page where the code executes. The $pro_id variable is from GET method for adding to cart. Therefore the $pro_id = $_GET[add_cart] which is in index.php. I will also include the index.php file bellow so if needed, one can take a look.
Quick answer would mean a lot. Thanks

NOTE: It works fine when one product is in the cart.
I'm trying to materialize pagination. I want to fetch like
$sql2 = "select * from phptest.memo order by num desc limit $start,$start+$scale";
and i used while paragraph to show memo and ripple (ripple database has parent field that what number of memo and it's order num primary field) but I think it seems like typed wrong code what should i do? It's image that I want make
Expected result:
Error:
<?php
session_start();
// echo "<a href='memo.php?page=$i'> $i </a>";
$scale=5; // page per writing
// start recored number newest writing is up
// $page 값에 다른 시작 레코드 넘버값, 가장 높은 글번호(최신글 부터 밑으로)
$start = ($page - 1) * $scale; //0,5,10 ...
if(!isset($_REQUEST["page"]))
{
$page = 1; // initialize seeing page
}else{
$page = $_REQUEST["page"];
}
require_once '../lib/dbconn.php';
$pdo = db_connect();
if(isset($_SESSION["userid"])){
$userid = $_SESSION["userid"];
}else{
$userid = "";
}
// start recored number newest writing is up
try{
//$sql = "select * from phptest.memo order by num desc";
$sql2 = "select * from phptest.memo order by num desc limit $start,$start+$scale";
$stmh = $pdo->query($sql2);
} catch (PDOException $ex) {`enter code here`
print "오류: ".$ex->getMessage();
}
$total_record = $stmh->rowCount();
$number = $total_record - $start;
// 전체 페이지 수 계산..
if ($total_record % $scale == 0)
$total_page = floor($total_record/$scale);
else
$total_page = floor($total_record/$scale) + 1;

The SQL doesn't like doing maths in the limit clause. Do it first in PHP:
$sql2 = "select * from phptest.memo order by num desc limit $start," . ($start+$scale);
After searching for a specific course the results are displayed correctly but once I change page it reverts back to displaying all of the available results. How do I keep the search term results?
Here's the code
<?php
$con = mysqli_connect("localhost", "root", "root", "courses");
// $total = mysqli_query($con, "SELECT count(title) as total")->fetch()['total']);
if(isset($_GET['searchword'])){
$searchword = $_GET['searchword'];
}
else {
$searchword = "";
}
$result = mysqli_query($con, "SELECT count(title) FROM course WHERE title LIKE '$searchword%'");
$row = mysqli_fetch_row($result);
// Total rows.
$rowstotal = $row[0];
//pages
$page = isset($_GET['page']) ? (int)$_GET['page'] : 1;
$perPage = isset($_GET['per-page']) && $_GET['per-page'] <= 100 ? (int)$_GET['per-page'] : 10;
$start = ($page > 1) ? ($page * $perPage) - $perPage : 0;
$pages = $rowstotal / $perPage;
$sql = "SELECT * FROM course WHERE title LIKE '%$searchword%' ORDER BY title ASC LIMIT {$start},{$perPage}";
$query = mysqli_query($con, $sql);
$resultsText = "$rowstotal results";
$resultsList = '';
while($row = mysqli_fetch_array($query, MYSQLI_ASSOC)){
$courseId = $row["id"];
$courseAward = $row["award"];
$courseName = $row["title"];
$courseDetails = $row["summary"];
$resultsList .= ''.$courseAward.' '.$courseName.' <br>'.$courseDetails.'<br/>';
}
mysqli_close($con);
?>

Your page links don't preserve the searchword parameter. Change this:
<a href="?page=<?php echo $x; ?>&per-page=<?php echo $perPage; ?>"<?php if($page === $x) { echo ' class="selected"'; } ?>><?php echo $x; ?></a>
to this:
<a href="?page=<?php echo $x; ?>&per-page=<?php echo $perPage; ?>&searchword=<?php echo $searchword; ?>"<?php if($page === $x) { echo ' class="selected"'; } ?>><?php echo $x; ?></a>
Well i'm trying to make a website as you can see, and i'm having difficulty with the "LOAD MORE" button, what i in-vision is that whenever someone clicks this button it would go through preferably a php code that tells the database to load in 5 more posts.
show_posts.php
<?php
$query = $con->query("SELECT * FROM `posts` ORDER BY `id` DESC LIMIT 5");
if( isset( $_POST['load'] ) ){
//code goes here
}
while($result = mysqli_fetch_assoc($query)){
// if video is empty then echo this line
if($result["video"] == ""){
$account_assoc = $result["account_assoc"];
$result2 = mysqli_fetch_assoc($con->query("SELECT * FROM `Accounts` WHERE username='$account_assoc' OR email='$account_assoc'"));
if($result2["username"] == ""){
$identifier = $result2["firstname"];
}else{
$identifier = $result2["username"];
}
if($result2['image'] == ""){
$image = "http://jnvbaghmara.nic.in/images/staff/Blank.png";
}else{
$image = 'data:image/jpeg;base64,'.base64_encode($result2['image']);
}
if($result['dislikes'] > 1){
$dislike = "<label style='color: red;'>".format_num($result['dislikes'])."</label> Dislikes";
}else{
$dislike = "<label style='color: red;'>".format_num($result['dislikes'])."</label> Dislike";
}
if($result['likes'] > 1){
$like = "<label style='color: #0096f3;'>".format_num($result['likes'])."</label> likes";

Also if there is anyway to make my code simpler, then i'm open to suggestions.
*I want the code to be php because i understand php more than i do js, jquery etc.
$postsNum = $_GET['num'];
$query = $con->query("SELECT * FROM `posts` ORDER BY `id` DESC LIMIT $postsNum");
The LOAD MORE button with a link: YOURURL?num=n
n can change by your php code.
