My code is working on PHP 7.4 and now I'm testing it with PHP 8 and getting following error_log:
PHP Fatal error: Uncaught TypeError: count(): Argument #1 ($value) must be of type Countable|array, string given in D:\localhost\htdocs\chat\dtc\engine\mysql\board_alerter.php:13
board_alerter.php is as given below:
<?php
if (!defined("_COMMON_")) {echo "stop";exit;}
include_once($ld_engine_path."inc_connect.php");
$m_result = mysqli_query($conn,"select new_mails from ".$mysql_table_prefix."users where id=$is_regist") or die("database error<br>".mysqli_error($conn));
if (mysqli_num_rows($m_result))
list($new_board_messages) = mysqli_fetch_array($m_result, MYSQLI_NUM);
if (!isset($new_board_messages)) $new_board_messages = "0";
mysqli_free_result($m_result);
$m_result = mysqli_query($conn,"select concat(subject,body) from ".$mysql_table_prefix."board where user_id=$is_regist") or die("database error: cannot retrieve mail-messages<br>".mysqli_error($conn));
$total = 0;
while ($row = mysqli_fetch_array($m_result, MYSQLI_NUM))
$total += count($row[0]);
$percentage = round($total / $max_mailbox_size *100);
mysqli_free_result($m_result);
?>
Please suggest me a fix

|
|
|
|
Replacing count($row[0]); with strlen($row[0]); should do it.

|
|
|

Yes it worked!!
Thank you!

I'm having a htaccess redirection issue which I am unable to find a solution by searching on the Internet and also I did several htaccess rewrite codes, but nothing helped me.
The URL has a part %3F
Please give me a correct solution to redirect following URL using htaccess:
https://www.example.com/folder/%3F
to
https://www.example.com/folder/

Quote: In this game you can develop whatever technologies. But you want to implement smile API.
Smile API just provide image and Solutions(Solution always come 1-9 Numbers ). image have simple maths quiz.
Every Time you call smile API ,Image and solution will be change.
You can do like quiz application. You want to validate that solution with user's answer.
You want to add this 3 components in this game
1.Software architecture- it's like model view controller, clean Architecture
2.even driven architecture- it's like GUI (login, Register)and buttons.
3.Interoperability - it's mean Use Smile Api
And you can get extra marks for Extra features. Question is the image .API response should be the solution.
Quote: When the Login button is pressed, initialize the game and call the API .Send the HTTP Get Request using API .After Login starts GUI .When initialized the game appears the question . When the user answers the question, Solution becomes the API Response and passes the data to the JSON object .Validate the Solution with the user's answer .If the user's input is equal to the solution (calculation is correct) the user can go to the next level and increase the score and also call the API .Quote: When calling the API get the data and divide into the string variables .In this need JSON array() instead of JSON object

Hey guys,
I run into a problem with developing a new project of mine, more specifically with a shortcode of mine.
About the website setup:
- I use wordpress
- I use Elementors template option to print out a template on on all pages belonging to the taxonomy "Marken".
- Custom post types are created with CPT UI and custom fields with ACF
I got the following shortcode, to print out the specific brand on the site iteself:
add_shortcode( 'MODELL', 'modell_shortcode' );
function modell_shortcode() {
$terms = get_the_terms( array(
'post_type' => 'fahrzeuge',
'taxonomy' => 'marken',
'hide_empty' => false,
) );
return ucwords($terms[1]->slug);
}
The code works fine put prints out the wrong brand. As you can see here Tesla – moinmobility.de[^] "Tesla" should be written in the text above but "Audi" is shown.
The same issue applies for the other shortcodes there should be written "0 €" instead of "345 €" etc.
Is this a problem with my shortcode? With Elementor? And how to fix this?
Searched a lot on Google, Blogposts and Forums but couldn't find a helpful answear. Hope someone here can help me

Probably by adding some numbers together. But you need to add more specific details to your question.

Bonjour, j'ai un soucis avec les privilèges utilisateurs (AUCUN, EDITEUR, ADMINISTRATEUR).
C'est à dire, en fonction des identifiants rentrés, on a accès à certaines liens du menu.
et malheureusement chez moi le menu ne s'affiche pas. Besoin d'aide, merci d'avance.
voici mon code :

There's a secret error somewhere in your secret code. You need to fix that.
Seriously, how do you expect anyone to be able to help you fix code we cannot see running on a server we cannot access, based solely on a brief description of the behaviour?
Edit your message and provide the relevant parts of your code, and a clear description of what the problem is, what you have tried, and where you are stuck. Remember to include the full details of any errors.

When we install Ubuntu Server all we get is terminal only access. I admit we can install necessary GUI like KDE, GNome etc.
But my concern is whether there would be any security concern to be taken care of when installing anything like this for an Ubuntu Server Azure or AWS? Because I guess with a GUI we also need to expose ports for RDP unlike Private/Public key using Putty.

Paste the start of your error message into Google, or your preferred search engine, and you will find the hundreds of times this exact question has been asked before.
The answer hasn't changed: mysql_query[^] returns false if the query fails. You need to test for that before trying to count the number of rows.
As to why your query failed, that's up to you. You haven't shown any code, nor the structure of your database, so nobody can tell you what the problem with your query is.

I want to solve a PHP issue
I have a db with 2 tables: first one is "document":
id | title |
================================
1 | equations |
2 | great |
3 | painting |
second one is "pic":
id | doc_id | description
===============================================
1 | 1 | "mathematics"
2 | 1 | "physic"
3 | 2 | "litterature"
4 | 2 | "art"
the "doc_id" is a foreign key, related to the id of the table "document"
this is my question: I'm trying to print for each title, all the descriptions related to it, example:
for the title "equations" , the foreign key related to it, is "doc_id =1"
wich means for "equations" i will print "matematics" and "physic"
the final table printed using PHP and SQL, on my browser, should be:
| tiltle | description
===============================================
| equations | mathematics, physic
| great | litterature , art
| painting |
Here's my code:
<pre><?php
$servername = "localhost";
$username = "root";
$password = "root";
$dbname = "doc-pic";
$conn = mysqli_connect($servername, $username, $password, $dbname);
$sql = "SELECT * FROM pic LEFT JOIN document ON pic.doc_id=document.id";
$result = mysqli_query($conn, $sql);
$sql1 = "SELECT title from document";
$result1 = mysqli_query($conn, $sql1);
?>
<table>
<?php
if (mysqli_num_rows($result1) > 0)
while($row = mysqli_fetch_array($result1)){?>
<tr>
<td><?php echo $row["title"]; ?></td>
</tr>
<?php if (mysqli_num_rows($result) > 0 )
while($row = mysqli_fetch_array($result)){
?>
<tr>
<td><?php echo $row["doc_id"]; ?></td>
<td><?php echo $row["description"]; ?></td>
</td>
</tr>
</td>
<?php }
} ?>
thanks in advance

<pre>I have an issue while calculating the column-like bank statement. actually, I am trying to calculate Opening Balance/today In /today Out / Closing Bal in MySQL PHP. I have two tables. material_infor `IN +` entry and material_approvefor `OUT -`. I am considering my opening balance was `123`.
I am new in PHP and I am here using Union All function. Please help me to create the function for getting Opening / In today / out today/closing calculation in my code.
`table- material_in`
| id | components_key | insert_date | credit |
|------|----------------|-------------|-------------|
| 1 | 12345 | 2021-04-16 | 100 |
| 2 | 12345 | 2021-04-16 | 50 |
`table- material_approve`
| id | components_key | insert_date | debit |
|------|----------------|-------------|-------------|
| 1 | 12345 | 2021-04-16 | 30 |
| 2 | 12345 | 2021-04-16 | 2 |
<pre>I am trying the code -
SELECT
`u`.`component_key`,
`u`.`insert_date`,
`u`.`transaction_qty`
FROM
(
SELECT
`components_key` AS `component_key`,
`insert_date`,
`credit` AS `transaction_qty`
FROM
`material_in`
UNION ALL
SELECT
`components_key`,
`insert_date`,
`debit` AS `transaction_qty`
FROM
`material_approve`
) u
WHERE
`u`.`component_key` = '12345'
ORDER BY
`u`.`insert_date`
DESC
the output comes -
| components_key | insert_date | transaction_qty|
|-------------|-------------|------------|
| 12345 | 2021-04-16 | 100 |
| 12345 | 2021-04-16 | 50 |
| 12345 | 2021-04-16 | 30 |
| 12345 | 2021-04-16 | 2 |
`output will be-`
| components_key | insert_date | openbal| today_in | today_out | closebal
|-----------|-------------|-------------|----------|-----------|---------|
|12345 | 2021-04-16 | 123 | 100 | 30 | 193 |
|12345 | 2021-04-16 | 193 | 243 | 2 | 241 |

This is not a php issue. This is Mysql.
Where are you stuck?
