Help me understand the parameters for mysqli_query.

Help me get this straight! I write a simple sniphfer for training purposes, which should record user data (ip, customer data, time) in Mysql database. But in the next section of the code.
```
$query = mysqli_query ($dblink, "INSERT INTO 'data' VALUES ('ip', 'usera', 'date')"); 
mysqli_query ($query, $dblink); 
mysqli_close ($dblink); 
```
There's a mistake.
```
Warning: mysqli_query() expects parameter 1 to be mysqli, boolean given in C:\OpenServer\domains\php.loc\include\sniff.php on line 14
```
The variable $dblink is a connection to the worst, and it's in another file. The OBD is successfully connected, but this error occurs when the crypt starts.

Right after the line, make the switching error.
```
echo mysqli_connect_error();
```
PS And show the whole code from the line to mysqli_close, or at least the connecting line itself.

The error suggests that you have a full number, not a WC_Order. Apparently, the id's coming in.Use this line to get the order object:$order_obj = new WC_Order( $order ); and put it in front of me.$return_url = $order_obj->get_checkout_order_received_url();

You need to group users by activity and product in the first step, and then group products by the groups of users. I use ORDER BY with GROUP_CONCAT(), so that the aggregated usernames are concatenated in the same order. SELECT x.usernames ,x.activity ,GROUP_CONCAT(p.product_name ORDER BY p.product_name) AS product_names FROM products p JOIN ( SELECT a.activity ,a.productId ,GROUP_CONCAT(u.name ORDER BY u.name) AS usernames FROM activities a LEFT JOIN users u ON u.id = a.userId GROUP BY 1, 2 ) x ON x.productId = p.id GROUP BY 1, 2 ORDER BY 1, 2; -> sqlfiddle Returns: USERNAMES | ACTIVITY | PRODUCT_NAMES -----------+------------+------------------------------ John | Bought | The Dark Knight Rises John,Peter | Bought | Batman Begins,The Dark Knight

I've been able to figure it out, I'll leave the code in case someone touches the same problem.<body> <form action="" method="post"> <div ng-app=""> <?php $i = 1; while ($row = mysqli_fetch_array($legalizaciones)) { ?> <div><?=$row['numero_recibo']?> <p>Numero 1 : <input type="number" ng-model="n1_<?=$i?>"></p> <p>Numero 2 : <input type="number" ng-model="n2_<?=$i?>"></p> <p>Numero 3 : <input type="number" ng-model="n3_<?=$i?>"></p> <p>Resultado : <input type="number" value="{{n1_<?=$i?>+n2_<?=$i?>+n3_<?=$i?>}}" class="monto" onkeyup="sumar();" readonly></p> </div> <br> <br> <?php $i= $i + 1; } ?> <br/ > <span>TOTAL </span> <input type="number" id="total" value="0" readonly/> </div> </form> </body> <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.22/angular.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script> <script> var f = function sumar() { const $total = document.getElementById('total'); let subtotal = 0; [ ...document.getElementsByClassName( "monto" ) ].forEach( function ( element ) { if(element.value !== '') { subtotal += parseFloat(element.value); } }); $total.value = subtotal; }; window.setInterval(f, 100); f(); </script>

What you can do is the following, in your PHP (visualize.php), instead of returning a string with the table, returning a string with the comma-separated values. Example:$resultado="codigo,tipo,status"; echo $resultado; On the page where the modal is, create a function to run when the modal is opened (show)var retorno = ['','', '']; $('#viewParamTipos').on('show.bs.modal', function (event) { var modal = $(this) modal.find('#id').html(retorno[0]); modal.find('#tipo').html(retorno[1]); modal.find('#status').html(retorno[1]); }); Note that the "return" array was created with empty content.To update their content before displaying the modal, you will need to make the following adjustment when reading the return of your php page (click on the "'.view_data" button)$.post('visualizar.php', dados, function (retorna) { retorno = retorna.split(','); //Converte a string em array $('#viewParamTipos').modal('show'); }); Here's some more information: https://getbootstrap.com/docs/4.0/components/modal/ https://www.w3schools.com/jsref/jsref_split.asp

What has the anonymous function that makes the correct operation possible?A very simple thing: an anonymous function is, in itselfan expression.Let's get a little clear:variable = expresión That sentence all a variable variable result evaluate the expresión.That makes it possible, for example, for this to work:var x = ( 5 * 2 + 10 ); The JavaScript engine first evaluates the position on the right operator =and it is the result of that assessment that I know asinga a variable.Now, let's see the result of evaluating a function:function algo( ) { } var variable = algo( ); Let's see. the parenthesis ( and ). That's it. It's the distinctive mark of one Call to function. When you meet nombre_de_variable ( , language understands that it is a expression, whose final result is the value returned by the call to the function nombre_de_variable.Therefore, in your example:body.onmousemove = mostrarPosMouse(event); Evaluation event (if not a local variable, it is used window.event in the browser).It's called the function mostrarPosMouse( ) with an argument: the result of the point 1.A body.onmousemove is assigned the returned value at the point 2.Yeah. expression You use an anonymous function, things happen in a similar way... but No. Identical:body.onmousemove = function (event) { mostrarPosMouse(event); }; The engine finds the keyword functionand understand that that's a function statement.The function statement return a reference to the newly created function.The reference obtained in 2 is used as a value to assign.We could say thatfunction (event) { mostrarPosMouse(event); }; it's, in a way, just like we did.{ return ( function( event ) { mostrarPosMouse( event ); ); } } The Mozilla Developer Network, like Almost. always, it has excellent documentation https://developer.mozilla.org/es/docs/Web/JavaScript/Guide/Funciones with a section on the https://developer.mozilla.org/es/docs/Web/JavaScript/Guide/Funciones#Expresiones_de_funci%C3%B3n .

You are obviously trying to define constants with the credentials to connect to the database. It can be done, but it doesn't make much sense, as in PHP the constants are a kind of global variables.Just like the ones http://php.net/manual/es/language.variables.predefined.php , access to a constant is global. Separate you can access constants from any site of the script without import from where. For more information on access, read the manual section http://php.net/manual/es/language.variables.scope.php . Source: http://php.net/manual/es/language.constants.php So, applying good programming practices, a constant would be defined to use it in several parts of the code... here what would interest to use in several parts of the code is the connection itself (e.g. through a kind of connection), so define remaining constants in this case. If you want to use constants anyway, the right way would be:DEFINE("HOST", "localhost"); DEFINE("USERNAME", "j8f5w8o7_finix"); DEFINE("PASSWORD", "yael2204"); DEFINE("DATABASE", "j8f5w8o7_finix"); $mysqli = new mysqli(HOST, USERNAME, PASSWORD, DATABASE); You will see that I have put them in capital, because this is what the convention of names requires (see previous link in the Manual).For the connection to the database it is advisable to have a class dedicated to the connection that returns a connection object, whenever you need it. To connect to the bd you can define simple variables as you do not need those variables to have a global scope, they will also occupy less memory than a constant.Example:$host="localhost"; $username="j8f5w8o7_finix"; $password="yael2204"; $database="j8f5w8o7_finix"; $mysqli = new mysqli($host, $username, $password, $database); Having a class that returns the connection object $mysqli the same would use the credentials locally and return the connection That's what you're interested in. The less public and less global your credentials, the better. So use DEFINE for connection credentials could be considered a bad practice.I also called the connection $mysqlibecause usually the connection object is called so, or $con, or $bd... is a matter of tastes and ... to apply convention rules of names, as $sql is usually used for queries such as SELECT ... FROM ..., INSERT INTO ...etc.

The best way to see current threads (including all foreground and background threads) is now with performance_schema. For example: mysql 5.7.3> select thread_id, name, type, PROCESSLIST_ID from performance_schema.threads; +-----------+----------------------------------------+------------+----------------+ | thread_id | name | type | PROCESSLIST_ID | +-----------+----------------------------------------+------------+----------------+ | 1 | thread/sql/main | BACKGROUND | NULL | | 2 | thread/innodb/io_log_thread | BACKGROUND | NULL | | 3 | thread/innodb/io_read_thread | BACKGROUND | NULL | | 4 | thread/innodb/io_read_thread | BACKGROUND | NULL | | 5 | thread/innodb/io_ibuf_thread | BACKGROUND | NULL | | 6 | thread/innodb/io_read_thread | BACKGROUND | NULL | | 7 | thread/innodb/io_read_thread | BACKGROUND | NULL | | 8 | thread/innodb/io_write_thread | BACKGROUND | NULL | | 9 | thread/innodb/io_write_thread | BACKGROUND | NULL | | 10 | thread/innodb/io_write_thread | BACKGROUND | NULL | | 11 | thread/innodb/io_write_thread | BACKGROUND | NULL | | 14 | thread/innodb/srv_lock_timeout_thread | BACKGROUND | NULL | | 15 | thread/innodb/srv_error_monitor_thread | BACKGROUND | NULL | | 16 | thread/innodb/srv_monitor_thread | BACKGROUND | NULL | | 17 | thread/innodb/srv_master_thread | BACKGROUND | NULL | | 18 | thread/innodb/srv_purge_thread | BACKGROUND | NULL | | 19 | thread/innodb/page_cleaner_thread | BACKGROUND | NULL | | 20 | thread/sql/signal_handler | BACKGROUND | NULL | | 22 | thread/sql/one_connection | FOREGROUND | 2 | +-----------+----------------------------------------+------------+----------------+ 19 rows in set (0.00 sec) I believe the background threads are fixed in number (the actual count will depend on some configuration settings such as innodb_read_io_threads and the number of innodb_purge_threads etc.) The FOREGROUND threads are one per connection + a potential of thread_cache_size on top of that.

In a mistake, it says you need to set up a list. NumbersAnd you have a list. Lines♪n = int(input()) table = [[0]*n for i in range(n)] for i in range(1, n): temp = [int(k) for k in input().split()] for j in range(len(temp)): table[i][j] = temp[j] table[j][i] = temp[j] for row in table: print(*row)

I'll assume one of these processors. PHP located HTML code and eventually header It doesn't work, it's becauseRemember that function header(s) only if the client has not yet been provided with the data. I mean, she has to go first in conclusion, there must be no HTML Tags, empty lines, etc. It is often a mistake when the code is read by file functions, like include or require, there are gaps or empty lines in the code that are made before the challenge. header(s)♪ The same problems may arise when a single PHP/HTML file is used.<html> <?php /* Этот пример приведет к ошибке. Обратите внимание * на тэг вверху, который будет выведен до вызова header() */ header('Location: http://www.example.com/'); exit; ?> quotation from documentation: http://php.net/manual/ru/function.header.php So the code should be at the top.

this inside function is a reference to the body itself. At the time you call arr2, you call a function placed inside the body to a position with index 2. She's in turn showing you the contents of the mass, the letters a,b and the function of 3 positions. You can play with it by putting, for example, inside this function into a global variable. For example,var a = 123 var arr = ["a", "b"]; arr.push(function() { a = this; alert( this ); }) arr2; And look how the variable changes a before the arr2 and after.

No, it's not an anonymous mass, it's a way to type the values of unknown object keys. https://www.typescriptlang.org/docs/handbook/advanced-types.html#index-types-and-string-index-signatures ) Signature{ name: string, [key: <type A>]: <type B> } Says that the property name with the string type will be exactly in object, and all the other keys with the type <type A> will contain type values <type B>♪ The name of the key (key and property) is unloaded and may be arbitrary.Specifically, in your example, an object in which there is an arbitrary number of string keys, each of which corresponds to the value of SimpleChange.
