Initially, I’m new to PHP and SQL, so take it easy if you have shaving in the code. I’m just testing the PHP and Mysql integration, I took an example table from a book and made a quick html page to pass the parameters.

HTML: (index.html)

    <html>
     <body>
      <form action="add.php">
        <p>Nome<input name="nome" type="text"/>
        <p>Principal Ingrediente<input name="principal" type="text"/>
        <p>Quantidade<input name="quant1" type="number"/>
        <p>Ingrediente Secundário<input name="segundo" type="text"/>
        <p>Quantidade<input name="quant2" type="number"/>
        <p>Instrução<input name="instrucao" type="text"/>
        <p><input type="submit"/>
      </form>
     </body>
    </html>

PHP: (add.php)

<html>
    <body>
        <?php 
        $nome = $_GET['nome'];
        $principal = $_GET['principal'];
        $quant1 = $_GET['quant1'];
        $segundo = $_GET['segundo'];
        $quant2 = $_GET['quant2'];
        $instrucao = $_GET['instrucao'];
        $db = new mysqli('localhost', 'root', 'Another2/', 'drinks');

        $sql = "INSERT INTO drinkfaceis(nome, principal, quant1, segundo, quant2, instrucoes) 
                VALUES(?, ?, ?, ?, ?, ?);";

        $stmt = $db->prepare($sql);
        if(!$stmt){
            echo 'erro na consulta: '. $db->errno .' - '. $db->error;
        }

        echo $nome;
        echo $principal;
        echo $quant1;
        echo $segundo;
        echo $quant2;
        echo $instrucao;

        $stmt->bind_param('ssisib', $nome, $principal, $quant1, $segundo, $quant2, $instrucao);
        $stmt->execute();
        ?>
    </body>
</html>

SQL script:

CREATE DATABASE drinks;
USE drinks;
CREATE TABLE drinkfaceis
(
    nome        VARCHAR(20),
    principal   VARCHAR(20),
    quant1      INT(10),
    segundo     VARCHAR(20),
    quant2      INT(10),
    instrucoes  BLOB
);

When testing does not give any error, he writes the value of the variables (which I put only to test), but when I go to phpMyAdmin and look at the table the data was not inserted.

And once again the code was correct, the problem was the autocommit deactivated.

When it is off you are required to tell the database that that command (an Insert/update/delete DML) must be executed permanently, this can be done in several ways via php, with the commit() for success and rollback() to cancel the instruction.
