I need your help with this small issue as my developing level is not the best In the room ( faraway :-) )
I would like to spread the results of my SQL request in 3 columns.
After the first 37 entries, I would like the entries 38 to 74 are filling the column #2, and column #3 over 74...
I hope it is clear.
please find below the code of my page:
<title>TITLE</title>
<link href="https://fonts.googleapis.com/css2?family=Montserrat:wght#700;800;900&display=swap" rel="stylesheet">
<style>
body {background-color: #000000;}
table {
background-color: #000000;
border-collapse: collapse;
width: 100%;
}
table, .table {
color: #fff;
font-family: "Montserrat", sans-serif;
font-size: 18px;
font-weight:800;
font-weight:Extra-bold;
}
tr:nth-child(even) {
background-color: #60451e;
}
</style>
<div class="container">
<div class="row">
<?php
include_once("inc/db_connect.php");
$sqlQuery = "SELECT name, GROUP_CONCAT(id ORDER BY id SEPARATOR ' | ') as grouped_id FROM developers GROUP BY name";
$resultSet = mysqli_query($conn, $sqlQuery) or die("database error:". mysqli_error($conn));
?>
<table id="editableTable" class="table table-bordered">
<tbody>
<?php while( $developer = mysqli_fetch_assoc($resultSet) ) { ?>
<tr id="<?php echo $developer ['id']; ?>">
<td><?php echo $developer ['name']; ?><br> <span style="color: #ffc000">BOXES > <?php echo $developer ['grouped_id']; ?></span></td>
</tr>
<?php } ?>
</tbody>
</table>
</div>
</div>
and I would like to keep a formatting similar to this for each entry:
echo $developer ['name']; ?><br> <span style="color: #ffc000">BOXES > <?php echo $developer ['grouped_id']; ?></span>
Thank you in advance

I have problem in my task where I suppose to display my record in horizontally with 3 columns
Unfortunately, my display is become vertical.
The task require us to use modulus (%) operator in order to display the records. The records are stored in database (id, title, picture, category, author). There are 11 books that store in database. Here is my PHP code:
<?php
include_once('config.php');
$result = mysqli_query($mysqli, "SELECT * FROM books ORDER BY id ASC");
?>
<style>
img {
border: 1px solid #ddd;
border-radius: 4px;
padding: 5px;
width: 200px;
}
.p2 {
font-family: Arial, Helvetica, sans-serif;
font-size: 14px;
padding-left: 10px;
}
.p3 {
font-family: Arial, Helvetica, sans-serif;
font-size: 14px;
padding-left: 10px;
color: blue;
}
</style>
<div class="container">
<center>
<h1>Koleksi Buku Peribadi</h1>
<table>
<?php
$x=11;
$y=3;
$i=$x % $y;
while($i && $book = mysqli_fetch_array($result)) {
?>
<tr>
<td>
<img src="Gambar-buku/<?php echo $book['picture'];?>">
<p class='p2'>Penulis:<span class='p3'> <?php echo $book['author'];?> </span>
<br> <i><?php echo $book['category'];?></i>
</p>
<center><button type="button">Details</button> </center>
</td>
</tr>
<?php
$i++; }
?>
</table>
</center>
</div>
Modulus is useful when you need to equally divide items into several categories.
Formally: index_of_category = index_of_item % number_of_categories
Practically: In your case, you have 3 categories (columns). For item with index i, you find index of its column with i % 3.
For making table layout work, you then need to:
print tr opening tag for every item belonging in column with index 0
print tr closing tag for every item belonging in column with index 2.
In my example, you can change number of columns easily by modifying $numberOfColumns variable.
<div class="container">
<center>
<h1>Koleksi Buku Peribadi</h1>
<table>
<?php
$numberOfColumns = 3;
for ($i = 0; (($book = mysqli_fetch_array($result)) !== null); $i++) {
$printRowOpeningTag = $i % $numberOfColumns === 0;
$printRowClosingTag = $i % $numberOfColumns === $numberOfColumns - 1;
if ($printRowOpeningTag) {?>
<tr>
<?php } ?>
<td><img src="Gambar-buku/<?php echo $book['picture'];?>">
<p class='p2'>Penulis:<span class='p3'> <?php echo $book['author'];?> </span>
<br> <i><?php echo $book['category'];?> </i>
</p>
<center><button type="button">Details</button> </center>
</td>
<?php if ($printRowClosingTag) { ?>
</tr>
<?php } ?>
<?php
} ?>
</table>
</center>
</div>
When using CSS for my DetailsTable the information I am getting from the database is not being displayed correctly in the table. All of that information is getting bunched up together and therefore isn't being laid out as a table.
If anyone could suggest why the information I am trying to get isn't being laid out in a table form that would be much appreciated
</head>
<body>
<div id="DetailsTable" >
<table>
<tr>
<th>Name</th>
<th>TypeOfShoe</th>
<th>Description</th>
<th>Price(£)</th>
<th>Fabric</th>
<th>Colour</th>
<th>Brand</th>
</tr>
</table>
<?php
$shoesID=$_GET['id'];
$stmt = $conn->prepare("SELECT shoes.name, shoes.images, shoes.description, shoes.price, types.typeOfShoe, types.fabric, types.colour, brands.name AS bname FROM shoes INNER JOIN types on types.types_id = shoes.type_id INNER JOIN brands on brands.brands_id = shoes.brands_id
WHERE shoes.id = :id");
$stmt->bindValue(':id',$shoesID);
$stmt->execute();
if ($shoes=$stmt->fetch()){
echo "<td>".$shoes['name']."</td>";
echo "<td>".$shoes['typeOfShoe']."</td>";
echo "<td>".$shoes['description']."</td>";
echo "<td>".$shoes['price']."</td>";
echo "<td>".$shoes['fabric']."</td>";
echo "<td>".$shoes['colour']."</td>";
echo "<td>".$shoes['bname']."</td>";
}
$conn=NULL;
?>
<br> <br/>
<div id="Image" >
<img src="<?php echo $shoes['images']; ?>" height="500px" width="500px" />
</div>
</div>
The CSS code is below.
body {
background-color: lemonchiffon;
}
#DetailsTable {
border-collapse: collapse;
width: 100%;
}
th, td {
text-align: left;
padding: 8px;
}
#Image{
display: block;
margin: auto;
width: 50%;
height: 10px;
clear: both;
}
You have closed the</table> tag before the php code, that maybe the problem

I have the code above to make my output from:
Client id Insurance
------------ ---------------
123 {"AA","EE","U"}
125 {"AA","UE"}
126 {"CU"}
124 {"UE"}
I want this:
Client id Number of rows Insurance
------------ ----------------------- --------------
123 3 rows AA,EE,U
125 2 rows AA,UE
126 1 rows CU
124 1 rows UE
Im not sure how to fix it, i tried add this line to my query:
concat(count(*), ' rows') AS rows
But it just gave me an error, any ideas on what I could do for the rows to come out and the "{" and '"' goes?
u can use explode function.
try this code
<?php while ( $row = pg_fetch_array ( $result ) ) { ?>
<tr>
<td><?php echo $row['client_id']; ?></td>
<td><?php echo implode(',',json_decode($row['insurance'])); ?></td>
<td><?php
$sRows = '';
if($row['iCnt'] > 0) {
$sRows = $row['iCnt']==1?' row':' rows';
}
echo ''.$row['iCnt'].$sRows;
?></td>
</tr>
JSON Parsing and Query issues are solved
<?php
error_reporting ( E_ALL );
ini_set ( 'display_errors', 1 );
require "connection.php";
$query = "SELECT client_id,
count(*) AS iCnt,
array_agg(insurance) AS insurance from vouchers

Change you query like this
SELECT client_id, concat(cast(count(*) AS char),' rows')
This works good in mysql. You have to type cast integer to string for concatenation
http://www.mysqltutorial.org/mysql-cast/
For PostgreSQL it's should be like this,
SELECT client_id,
count(*) AS cnt,
''||count(*)||' rows' AS concatString
https://www.postgresql.org/docs/8.3/static/functions-string.html
You can add If and else like this on query
SELECT client_id,
CASE WHEN count(*)>0 THEN
CASE WHEN count(*)==1 THEN ''||count(*)||' row'
ELSE ''||count(*)||' rows' END
ELSE ''
END AS concatenatedString
I don't know about the performance
Postgres nested if in case query
You want to use array_to_string:
SELECT
client_id,
concat(count(*), ' rows'),
array_to_string(array_agg(insurance),',') AS insurance
FROM vouchers
WHERE parsing_date=CURRENT_DATE
GROUP BY client_id
I have view file on my app there is code array I want to get first object of that array without going in loop.
<?php
$result = array_chunk($products->result_array(), 3);
foreach($result as $products){ ?>
<table style="width:100% style="page-break-after:always;" >
<tr>
<?php
foreach($products as $productArray){
$product = (object) $productArray;
echo '<td>';
?>
<div style="width: 100%; height: 210px; border: 1px solid #dddddd; margin: auto 5px 5px 0; padding: 5px;">
<div class="box-header">
<p class="box-title"><FONT SIZE=12><?php echo $product->product_name; ?></FONT></p>
</div>
<div style="height: 100px; text-align: center;">
<?php echo '<img src="'.'uploads/'. $product->photo.'" class="img-responsive" style="height:100px !important; width: 150px !important" />'; ?>
</div>
<div style="clear: both"></div>
<table class="table table-responsive">
<tr>
<th><FONT SIZE=12>ID</FONT></th>
<td><FONT SIZE=14><?php echo $product->product_id; ?></FONT></td>
</tr>
$result is array of object I'm getting from a form. In below you can clearly see I'm chunking it to 3 more array and looping though individual objects and getting their details to html for example.
<tr>
<th><FONT SIZE=12>ID</FONT></th>
<td><FONT SIZE=14><?php echo $product->product_id; ?></FONT></td>
</tr>
I want to get the first object details let's say want get $product->product_name of first object of result array without going in loop how to achieve that.

ok man as i said u need to change your way of writing codes but about your specific question use this:
$result = array('a', 'b', 'c', 'd', 'e');
reset($array);
$first = current($array);
you can check this:
http://php.net/manual/en/function.reset.php
http://php.net/manual/en/function.current.php
But still about your way of coding. u should soon go to MVC or such ways of programming so u should separate your view and coding logics
like u may have a page like view_profile.php which is going to show user's information. in regular coding u have this:
view_profile.php:
<?php session_start();
// you check sessions to see if the user is logged in and has the right to view this page.
// like:
if ($_SESSIONS['is_user_logged_in']){
$username=$_SESSIONS['username'];
$name=$_SESSIONS['name'];
// ....
}else{
header('location: ./login.php');// if user is not authenticated u redirect to login page
exit();// prevents the rest of codes to be shown and executed
}
?>
<html>
<head>
<title>View <?php echo $name; ?>'s profile</title>
</head>
<body>
<div>Name: <span><?echo $name; ?></span></div>
......
</body>
</html>
But in a better way u can do it like this:
you have files like
'view_profile.htm' // holds the HTML
'view_profile.php // holds the PHP logic
'inc.php' // holds some useful functions that help you in writing PHP logic
view_profile.htm
<html>
<head>
<title>View <?php echo $name; ?>'s profile</title>
</head>
<body>
<div>Name: <span><?echo $name; ?></span></div>
......
</body>
</html>
inc.php
<?php
function ses_start(){
if(!session_id()){
session_start();
}
}
function ses_get($key){
ses_start();
if(!empty($_SESSION[$key])){
return $_SESSION[$key];
}
return NULL;
}
function ses_set($key,$val){
$_SESSION[$key]=$val;
}
function is_user_loggedin(){
ses_start();
if(!empty(ses_get('is_user_loggedin')){
return true;
}
return false;
}
function go($to){
header('location: '.$to);
exit();
}
//and lots of useful functions that help u connect and work with data base.
view_profile.php
<?php
include('inc.php');
if(is_user_loggedin(){
$username=ses_get('username');
$name=ses_get('name');
//...
}else{
go('login.php);
}
include('view_profile.html); // and u call the .htm file that holds the HTML the view file)
?>
this was a simple sample of separating codes logic(php codes) from views(html tags)
and also u may search about MVC Model-View-Controller and try working with simple MVC frameworks.
It's me again, sorry...
I've been looking for the answer right in this forums, but there are no posts has been solved. I don't know if the questioner has been resolved the problems and not given a solved comment or something like that. All the comments/replies from the questioner is 'not work' or 'get some new errors' ect.
Now my scripts has worked before I put pagination scripts on them, but again errors in 'mysqli'. The errors are:
Warning: mysqli_query() expects at least 2 parameters, 1 given in C:\xampp\htdocs\paging\index.php on line 8
Warning: mysqli_fetch_row() expects parameter 1 to be mysqli_result, null given in C:\xampp\htdocs\paging\index.php on line 9
My scripts contained two files:
index.php:
<?php
$con = mysqli_connect("localhost", "root", "", "db_book") or die(mysqli_error($con));
$per_page = 3;
//getting number of rows and calculating no of pages
$sql = "SELECT COUNT(*) FROM flipbook";
$result = mysqli_query($sql);
$count = mysqli_fetch_row($result);
$pages = ceil($count[0]/$per_page);
?>

Thanks again...thank you...
best regards,
The error message is quite descriptive and clear: The first parameter to mysqli_query should be the connection handle.
Instead of $result = mysqli_query($sql);, use $result = mysqli_query($con, $sql);
