Barand's post in w3 Schools css colors was marked as the answer
If that colour does exist it should probably be included with the other w3- classes and not out there on its own.

Barand's post in How to have pagination in search results page? was marked as the answer
Firstly, you need corectly formatted query stringd (you have another "?" before page= instead of a "&")
Secondly you need to pass the search value (urlencodeed) and a submit value (1)
echo '<a class="paging" href="?search='.urlencode($_GET['search']).'&submit=1&page=' . ($page + 1) . '">Forward</a>';

Barand's post in How to count duplicated values in a table and display it? was marked as the answer
$res is NOT an array, it is a result object. Therefore your loop never executes.
Don't post pictures of code, post code.

Barand's post in Need code to not only see one href site, but how to show more than one. was marked as the answer
Use an array - it cuts out a lot of repetetive code
$domains = [ "bscscan" => "bscscan.com", "tronscan" => "tronscan", // .com ??? "dgb" => "dgb.com", "hecoinfo" => "heco.com", "polygonscan" => "polyn.com", "rvn" => "rvn.com", "etherscan" => "ethn.com", "thundercore" => "tttn.com", "solscan" => "solscan.com" ]; $address = strtolower($checkSqlRow["ADDRESS"]); echo "<td><a href='https://{$domains[$checkSqlRow["BLOCKCHAIN"]]}/token/$address'>$address</a></td>";

Barand's post in PDO update sql form not working was marked as the answer
If you know it's Y-m-d why have you specified Y/m/d ???
It's the <input type='date'> that is using the locale to display dd/mm/yyyy. It posts it to your code as yyyy-mm-dd as the print_r($_POST) shows...
All the clues are there but you seem to be ignoring them

Barand's post in Getting var from database, then getting record based on it was marked as the answer
try
$sql = "SELECT users_galaxyViewSystem FROM users WHERE users_id = 1"; $result = $conn->query($sql); $row = $result->fetch_assoc(); $testowanySystem = $row['users_galaxyViewSystem']; However, you should be using a single query with a JOIN instead of two queries
$sql = "SELECT planets_name FROM planets p JOIN users u ON p.planets_starsystem = u.users_galaxyViewSystem WHERE planets_galaxy = $testowanaGalaktyka AND planets_planet = $testowanaPlaneta AND users_id = 1 "; $result = $conn->query($sql); foreach ($result as $row) { echo $row['planets_name'].'<br>'; }

Barand's post in Php mysql refresh data was marked as the answer
Here's an alternative using PHP to do to the date arithmetic
<?php // create pdo connection here $date = $_GET['date'] ?? date('Y-m-d'); // date defaults to today if no input $days = $_GET['days'] ?? 0; // days defaults to 0 $dt = new DateTime($date); $newdate = $dt->modify("$days days")->format('Y-m-d'); $disabled = $newdate == date('Y-m-d') ? 'disabled' : ''; // if today, disable tomorrow button $res = $pdo->prepare("SELECT * FROM cercles WHERE dates = ? "); $res->execute([$newdate]); ?> <!doctype html> <html> <head> <title>Sample</title> <style type="text/css"> </style> </head> <body> <form> <button name='days' value='-1'><</button> <input type='date' name='date' value='<?=$newdate?>' > <button name='days' value='1' <?=$disabled?> >></button> </form> <table> <?php // output your data rows here ?> </table> </body> </html>

Remove those echo "jpeg"; etc.

Barand's post in I cannot get username from the second table was marked as the answer
No, you really don't want to do that - use a single query which joins the two tables on the user_id.
SELECT users_username FROM users u JOIN planets p ON u.users_id = p.planets_ownerid WHERE planets_galaxy = $testowanaGalaktyka AND planets_starsystem = $testowanySystem AND planets_planet = $testowanaPlaneta";

Barand's post in First Array Item doesn't show as other is table was marked as the answer
Te original html markup was inconsistent. I cleaned up the output too, but slightly differently. I couldn't see the point of separate tables (you can more easily guarantee consistency with a single one)
echo "<table border='1' class='table'>"; // foreach loop to ping IP and check if alive or dead & dispaly result foreach ($systems as $ip) { unset($result); $successValue = "DOWN"; exec("ping -n 1 $ip[ip]", $result); foreach($result as $line) { if (strpos($line,$good) == TRUE){ $successValue = "UP"; } } echo "<tbody> <tr> <td>IP Address: {$ip['ip']}</td> <td>Unit Name: {$ip['name']}</td> </tr> <tr> <td>Status is: $successValue</td> <td>" .

Barand's post in File extension when mixing PHP and HTML was marked as the answer
Yes.
PHP code in an .html file will not be processed.
However, a .php file does not need to contain any PHP code; it can just contain HTML and will function as an .html file.

PS
Also, require is not a function
The $pdo variable is created inside the code within your page scope.

Barand's post in Getting no data with if($stmt -> fetch()) was marked as the answer
You need to turn the mysql error reporting.
Your function's query gets 3 result columns and binds ony 2 of them.
Also the over number and ballinover values will be meaningless in that query as it uses an aggregation function.

Barand's post in Create a pdf from my website was marked as the answer
The most common one, I think, is FPDF
Another one, which is an enhanced version of that one, is TCPDF but I find the documentation a nightmare (the source file itself seems the only place). There are lots of example but it is difficult to know what the arguments for the methods are without a decent reference manual. For example
// Image example with resizing $pdf->Image('images/image_demo.jpg', 15, 140, 75, 113, 'JPG', 'http://www.tcpdf.org', '', true, 150, '', false, false, 1, false, false, false); You then have to dig into the source file to find

If not specified or equal to zero, it is automatically calculated. * @param $h (float) Height of the image in the page.

Luckily that same manual applies largely to TCPDF - although not the extras that TCPDF has. The most useful addition is the tcpdf::WriteHTML($html_string) method which renders html markup as PDF. I haven't used that facility much so I'm not sure how well it uses CSS.
Other improvements are better rendering of non-latin text (eg Arabic) and the ability to embed SVG graphics.
