When posting your question please:- Choose the correct forum for your message. Posting a VB.NET question in the C++ forum will end in tears.
- Be specific! Don't ask "can someone send me the code to create an application that does 'X'. Pinpoint exactly what it is you need help with.
- Keep the subject line brief, but descriptive. eg "File Serialization problem"
- Keep the question as brief as possible. If you have to include code, include the smallest snippet of code you can.
- Be careful when including code that you haven't made a typo. Typing mistakes can become the focal point instead of the actual question you asked.
- Do not remove or empty a message if others have replied. Keep the thread intact and available for others to search and read. If your problem was answered then edit your message and add "[Solved]" to the subject line of the original post, and cast an approval vote to the one or several answers that really helped you.
- If you are posting source code with your question, place it inside <pre></pre> tags. We advise you also check the "Encode HTML tags when pasting" checkbox before pasting anything inside the PRE block, and make sure "Ignore HTML tags in this message" check box is unchecked.
- Be courteous and DON'T SHOUT. Everyone here helps because they enjoy helping others, not because it's their job.
- Please do not post links to your question in one forum from another, unrelated forum (such as the lounge). It will be deleted.
- Do not be abusive, offensive, inappropriate or harass anyone on the boards. Doing so will get you kicked off and banned. Play nice.
- If you have a school or university assignment, assume that your teacher or lecturer is also reading these forums.
- No advertising or soliciting.
- We reserve the right to move your posts to a more appropriate forum or to delete anything deemed inappropriate or illegal.
When answering a question please:
- Read the question carefully
- Understand that English isn't everyone's first language so be lenient of bad spelling and grammar
- If a question is poorly phrased then either ask for clarification, ignore it, or mark it down. Insults are not welcome
- If the question is inappropriate then click the 'vote to remove message' button
Insults, slap-downs and sarcasm aren't welcome. Let's work to help developers, not make them feel stupid.
cheers,

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 :
class/Usermanager.php
class Usermanager {
private $db;

while($row = $stmnt->fetch(PDO::FETCH_ASSOC)) {

i have three condition like if(isset($_POST['search']) & !empty($_POST['searchdata']) ) and if(isset($_POST['search']) & !empty($_POST['seardate']) ) and else . these are searching input text field name searchdata and searchdate and esle if empty.
when first condition is true pagination is aslo create according to is t condition similarly on both two condition pagination is created.but confusion when i click on pagination cursor goes to else condition and again all page is shown in pagination.what i can doing wrong... i want if pagination is created in first condition and i click on pagination the cursor should be goes to first condition and the pagination is created upon second condition and i click it should go to second part not to else.

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?

I was using netbeans for php development before, now VSCode.
My question is why every time I run / load a page, VSCode opens a new blank window... even though VScode is already open... why!? It is true even when I am not debugging!
Even when I run the most basic code to debug,
<?php
phpinfo();
?>
it always opens a new VS Code Window (Untitled-1). Then, let say I press Reload, it again opens the same blank screen.
I am using "PHP Debug" as a extension, and my launch.json is:
{
"version": "0.2.0",
"configurations": [
{
"name": "Listen for Xdebug",
"type": "php",
"request": "launch",
"port": 9000
}
]
}
I do not want to open a new vs window each page I debug. How to fix that?

When you run a website from VS Code it opens the browser? Is that what you are asking about?

Pasting your error message into Google gives 211,000 results where other people have asked exactly the same question:
mysqli_fetch_array() expects parameter 1 to be mysqli_result, bool given - Google Search[^]
Or you could check the documentation:
Returns false on failure. For successful queries which produce a result set, such as SELECT, SHOW, DESCRIBE or EXPLAIN, mysqli_query() will return a mysqli_result object. For other successful queries, mysqli_query() will return true.
So either your query is failing, or it doesn't return a result set.
We can't tell you which, since you haven't shown us any of your code.

What language is this supposed to be? And exactly what do you mean by "echo the numbers" ?
If it is PHP then see PHP: list - Manual[^].
