PHP Notice: Undefined offset: 1 in...” exlode

magpie QA Engineer

I read a lot of things about this mistake, but I never understood how to fix it.

foreach($data as $date => $stat):
    $from = htmlspecialchars(trim(explode(" - ",$date)[0]));
    $to = (trim(explode(" - ",$date)[1])=='') ? $from : htmlspecialchars(trim(explode(" - ",$date)[0]));
    $html .= "<tr><td colspan='6'><hr></td></tr>\r\n";

error in line 207

$to = (trim(explode(" - ",$date)[1])=='') ? $from : htmlspecialchars(trim(explode(" - ",$date)[0]));

Rossere

Thank you all. The code is as follows:

foreach($data as $date => $stat):
    if(isset($date[1])){
        $to = htmlspecialchars(trim(explode(" - ",$date)[0]));
        $from = htmlspecialchars(trim(explode(" - ",$date)[0]));
    }else{
        $to = htmlspecialchars(trim(explode(" - ",$date)[1]));
    }
}

In the first code, I used a non-existent variable. $date[1]♪

You are testing if there is a post parameter for name, if it exists, it only mounts the query to this field. If there is no you mount what seems to me a copmplete return for all paged records of the table.One possible solution would be to mount the query base, and then test each of the possible parameters as filters and go concatenating on query.In the following example I am considering only 3 parameters and changing only the PHP part placed in the question related to filtering with criteria, so that you understand the solution logic and complement in your context, also note that I do not know your database so the field names are suggestions. $sql = "SELECT * FROM cadastro"; $where = ""; if(isset($_POST['nome'])) { $pesquisar = $_POST['nome'] ; $where .= "nome LIKE '%$pesquisar%'"; } if(isset($_POST['nome_mae'])) { $pesquisar = $_POST['nome_mae'] ; // esta linha testa se a variável where já tem conteúdo, se sim adiciona o // AND caso não inicia ela vazia $where = empty($where) ? "" : $where . " AND "; $sql .= "nome_mae LIKE '%$pesquisar%'"; } if(isset($_POST['cidade'])) { $pesquisar = $_POST['cidade'] ; // esta linha testa se a variável where já tem conteúdo, se sim adiciona o // AND caso não inicia ela vazia $where = empty($where) ? "" : $where . " AND "; $sql .= "cidade LIKE '%$pesquisar%'"; } // finaliza a construção da query, se where for vazio somente limita o resultado // caso contrário adiciona a cláusula $sql .= empty($where) ? "" : " WHERE " . $where; $sql .= " LIMIT 30"; $resultado_msg_contatos = mysqli_query($conn , $result_msg_contatos); If you don't know the ternary operator I used in the variable tests $where https://www.php.net/manual/pt_BR/language.operators.comparison.php#language.operators.comparison.ternary .

Dude, I got two things to talk to you about. The first is that there is no better way to create a relational model. The second is that there is no right and wrong. When it comes to relational model, you have yes some concepts and techniques that help you build one that was maintainable and elegant, but does not mean that if you do not follow them, it will be wrong.Some points I can observe from your model that you can improve:Your client entity only has a primary key and a foreign key. It doesn't make much sense to have an entity to keep any information. Unless you're an associative entity, like your "producer" entity.When creating an entity, you can think as follows (help me a lot, I don't know if it will help you): Your "user" entity for example. Know that since you have placed "name" as the attribute of this entity, there will be no person, in your model, who is not user, because you will not be able to name it, since this attribute is user. So what I would do would be to create a person entity, which relates to the user in a relationship 1 to 1. That person entity would have the name attribute.Look for good modeling practices, especially for abbreviations, typing and uppercase/lowcase letters. It avoids redundancy and confusion when it comes to returning to the model after a while. Unfortunately, I don't have any sources to indict you, because I haven't read about it for a while, but I believe you've still been proud of these standards.Email is an attribute that I would separate in an entity. Just like you did with Endereco. The email has an address, a service (gmail, hotmail, etc.), among others.

before cleaning your post you should be cachar if you are getting with an if(isset($_POST['dato'])) and with that returning an error, the other is where you receive your response down there put a console.log(response); so you will see which the answer of the server, because it seems that you will never respond to this response.type a bit your response.

As I see it, and as I understand, you need your arrays from the beginning, to combine into one only that you can handle to paint them in a specific table. I see you can do it in two ways:Using https://www.php.net/manual/en/function.array-combine.php Knowing that you have different arrays between yourself and need to join them, you can use array_combine as follows:You create a new array with the keys you need, in my case I plant it like this:$keys = ['id', 'tipo_compra', 'fecha_compra', 'concepto', 'debe', 'haber', 'saldo']; You combine your arrays with the keys as follows:$id_comp = [8, 8, 8, 8, 8]; $tipo_comp = ['Egreso', 'Egreso', 'Egreso', 'Egreso', 'Egreso', 'Egreso']; $fecha_comp = ['2021-10-09', '2021-10-09', '2021-10-09', '2021-10-09', '2021-10-09', '2021-10-09']; $concepto = ['Sueldo Agosto 2021 Juan Pinto Guerra', 'Sueldo Agosto 2021 Jerson Carrillo Salas', 'Sueldo Agosto 2021 Juan Obando Carcamo', 'Sueldo Agosto 2021 Douglas Medel Perez', 'Sueldo Agosto 2021 Cristian Leiva Argel', 'Sueldo agosto 2021 Rodrigo Mora bello']; $debe = ['1.672.432', '407.117', '1.244.522', '852.207', '1.513.820', '756.544']; $haber = [0, 0, 0, 0, 0, 0]; $saldo = ['1.672.432', '2.079.549', '3.324.071', '4.176.278', '5.690.098', '6.446.642']; $data = array_combine($keys, [ $id_comp, $tipo_comp, $fecha_comp, $concepto, $debe, $haber, $saldo ]); This should result in something like this: [ "id" => [ 8, 8, 8, 8, 8, ], "tipo_compra" => [ "Egreso", "Egreso", "Egreso", "Egreso", "Egreso", "Egreso", ], "fecha_compra" => [ "2021-10-09", "2021-10-09", "2021-10-09", "2021-10-09", "2021-10-09", "2021-10-09", ], "concepto" => [ "Sueldo Agosto 2021 Juan Pinto Guerra", "Sueldo Agosto 2021 Jerson Carrillo Salas", "Sueldo Agosto 2021 Juan Obando Carcamo", "Sueldo Agosto 2021 Douglas Medel Perez", "Sueldo Agosto 2021 Cristian Leiva Argel", "Sueldo agosto 2021 Rodrigo Mora bello", ], "debe" => [ "1.672.432", "407.117", "1.244.522", "852.207", "1.513.820", "756.544", ], "haber" => [ 0, 0, 0, 0, 0, 0, ], "saldo" => [ "1.672.432", "2.079.549", "3.324.071", "4.176.278", "5.690.098", "6.446.642", ], ] Having an arrangement like the one I show you, you should be able to make use of foreach nests to go through what you need and extract the data:foreach($data as $key => $value) { echo $key."\n"; echo "--------------\n"; foreach($value as $key => $val) { echo $val."\n"; } echo "--------------\n"; } Having a result like this:id 8 8 8 8 8 tipo_compra Egreso Egreso Egreso Egreso Egreso Egreso fecha_compra 2021-10-09 2021-10-09 2021-10-09 2021-10-09 2021-10-09 2021-10-09 concepto Sueldo Agosto 2021 Juan Pinto Guerra Sueldo Agosto 2021 Jerson Carrillo Salas Sueldo Agosto 2021 Juan Obando Carcamo Sueldo Agosto 2021 Douglas Medel Perez Sueldo Agosto 2021 Cristian Leiva Argel Sueldo agosto 2021 Rodrigo Mora bello debe 1.672.432 407.117 1.244.522 852.207 1.513.820 756.544 haber 0 0 0 0 0 0 saldo 1.672.432 2.079.549 3.324.071 4.176.278 5.690.098 6.446.642 Using https://www.php.net/manual/en/function.array-merge.php To make use of the array_merge, you must modify your given arrays a bit, and add them to the arrays. keys you need to identify them, as I put it in the example:$id_comp = ['id' => [8, 8, 8, 8, 8]]; $tipo_comp = ['tipo_compra' => ['Egreso', 'Egreso', 'Egreso', 'Egreso', 'Egreso', 'Egreso']]; $fecha_comp = ['fecha_compra' => ['2021-10-09', '2021-10-09', '2021-10-09', '2021-10-09', '2021-10-09', '2021-10-09']]; $concepto = ['concepto' => ['Sueldo Agosto 2021 Juan Pinto Guerra', 'Sueldo Agosto 2021 Jerson Carrillo Salas', 'Sueldo Agosto 2021 Juan Obando Carcamo', 'Sueldo Agosto 2021 Douglas Medel Perez', 'Sueldo Agosto 2021 Cristian Leiva Argel', 'Sueldo agosto 2021 Rodrigo Mora bello']]; $debe = ['debe' => ['1.672.432', '407.117', '1.244.522', '852.207', '1.513.820', '756.544']]; $haber = ['haber' => [0, 0, 0, 0, 0, 0]]; $saldo = ['saldo' => ['1.672.432', '2.079.549', '3.324.071', '4.176.278', '5.690.098', '6.446.642']]; Then make use of the array_merge as follows:$data = array_merge($id_comp, $tipo_comp, $fecha_comp, $concepto, $debe, $haber, $saldo); And by making use of the foreach anit of the previous example, you would get the same resultI'll leave you. http://sandbox.onlinephpfunctions.com/code/9e7dd2832b49dc37109e54c6de6027155a9e5281

Try to use thevar_dump($codigo); the var_dump is a function shows structured information about one or more expressions including its type and value, it serves you to see the value of that variable, if $code comes out NULL it is that this emptied so you can't do the query

The two selections will have to be made separately but can bring the result at once by combining the two selections in a third. O select can return any information, even if it does not depend on the database. In this case you will receive a result where the "field" total will represent the first consultation and totalMaior will represent the second.SELECT (SELECT COUNT(*) FROM `tabela`) AS total, (SELECT COUNT(*) FROM `tabela` WHERE `valor` > 1) AS totalMaior; In PHP would use something like this:$resultado = mysqli_query($conexao, "SELECT (SELECT COUNT(*) FROM `tabela`) AS total, (SELECT COUNT(*) FROM `tabela` WHERE `valor` > 1) AS totalMaior;"); $campos = mysqli_fetch_array($resultado, MYSQLI_ASSOC); echo $campos["total"]; echo $campos["totalMaior"]; https://github.com/maniero/SOpt/blob/master/PHP/Database/MultipleQuerys.php .

var serie = 1; for (var i = 2; serie <= 100; i++) { console.log('Interacion: ' + i + ' : ' + serie); serie += i; } The cycle for consists of three parts:Initialization of the variable: var i = 0Condition: i.Increase of the variable by which it was: i+These parts may be omitted or not depending on your needs, as well as initializing several variables, putting multiple conditions and increasing several variables.In you cycle for instead of putting i.Put series: 100 in this way you will achieve the expected result.Or you can sum it up like this:for (var i = 2, serie = 1; serie <= 100; i++) { console.log('Interacion: ' + i + ' : ' + serie); serie += i; } This way the code is shorter as you delete the statement of the variable since you declare it within the parts of the cycle for.And if you want to sum it up more then put this on:for (var i = 1, serie = 1; serie <= 100; i++, serie += i) { console.log('Interacion: ' + i + ' : ' + serie); } La variable also increases within one of the parts of the cycle for.

There's a difference. func(1); - The type of variable will be integer♪ func('1'); in this case, the variable transferred to the function will have a type string♪ If you're not interested in the type of variable, there's no difference. If there's a difference in processing time, it's a small one.

Not Apache Server adds protocol, but a browser. The request is on the server with the protocol. On the server's side, we need to set up the necessary protocols and everything.

Some differences:SOAP 1.1 is based on XML 1.0 while SOAP 1.2 in XML Information Set (Infoset XML). The information set XML (infoset) provides a way to describe the document XML with scheme http://pt.wikipedia.org/wiki/XML_Schema . This way of describing the document XML helps reveal other "serialization" formats, such as a binary format protocol.SOAP 1.2 provides the ability to officially define shipping protocols except by using the HTTP, while the supplier complies with the bond structure that is set to SOAP 1.2. While HTTP is ubiquitous, not as reliable as other transports, including TCP/IP and MQ. SOAP 1.2 provides a more specific definition of the SOAP processing model that removes many of the ambiguities that can lead to interoperability errors, in the absence of the profiles Web Services-Interoperability (WS-I). The major differences are practically larger and significant in SOAP 1.2, an evlolution in the form of consuming and providing.

The problem is that the free hosting service offered by 000webhost has deactivated the Remote MySQL functions, which is why I return null to all values, as it is the server itself that does not allow access to them. The solution would be to buy a host.
