How to list rows table values

1. How can I list column values in a <table> ?

Assuming as a base that you already have a connection to the database through PHP you could list values of a table in a very simple way.

To begin we can receive the data from the database, it is based on them that our table will be generated dynamically.

    $resultado = array(); // Cria um array para receber o resultado
    $query = "SELECT * FROM <nome_da_sua_tabela_aqui>"; // Expressão SQL que irá ser executada
    $result = mysqli_query($this->connection, $query); // Executa a consulta com base na query
    $resultado = $result->fetch_all(MYSQLI_ASSOC); // Faz uma associação

Having the result / data we will show them in the table.

<table id="datatable" class="table table-striped table-bordered" cellspacing="0" width="100%">
    <thead>
    <tr>
        <th>Name</th>
        <th>Position</th>
        <th>Office</th>
        <th>Age</th>
        <th class="disabled-sorting text-right">Actions</th>
    </tr>
    </thead>
    <tfoot>
    <tr>
        <th>BANDEIRA</th>
        <th>TIPO</th>
        <th>BIN</th>
        <th>QUANTIDADE</th>
        <th>VENDEDOR</th>
        <th class="disabled-sorting text-right">Ações</th>
    </tr>
    </tfoot>
    <tbody>
    <?php foreach ($resultado as $row) { ?>
        <tr>
            <td><?php echo $row['nome_da_coluna_que_quer_mostrar_aqui']; ?></td>
            <td><?php echo $row['nome_da_coluna_que_quer_mostrar_aqui']; ?></td>
            <td><?php echo $row['nome_da_coluna_que_quer_mostrar_aqui']; ?></td>
            <td><?php echo $row['nome_da_coluna_que_quer_mostrar_aqui']; ?></td>
            <td class="text-right">
                <a href="#" class="btn btn-info btn-link btn-icon btn-sm like"><i class="fa fa-heart"></i></a>
                <a href="#" class="btn btn-warning btn-link btn-icon btn-sm edit"><i class="fa fa-edit"></i></a>
                <a href="#" class="btn btn-danger btn-link btn-icon btn-sm remove"><i class="fa fa-times"></i></a>
            </td>
        </tr>
    <?php } ?>
</table>

Within the table we will have several rows, or rather several tr . In the first step we get the data from the database, and from them we will show the data in the tables based on foreach , which provides an easy way to iterate over arrays.

At each iteration, the value of the current element is assigned to $ row and internal pointer of the array advances one position (then in the next iteration, whether you are looking at the next element, or the database row).

More information about foreach here .

Here in this tutorial you have a complete guide, in case you have not done the connection to the bank with PHP.

2. I need to create a form that does a POST on the page itself with all values of <td>

For this you have two options, which I know. One is the most recommended and another would be a gambiarra, which I would not recommend.

First you could generate several hidden inputs that would store those table values, or rather table rows.

The second option is to use AJAX, and soon I assume you know it. Also, I'm going to use jQuery here to make it easier.

You could get the click event of the submit button and receive the td data. It would look more or less like this.

 $(document).ready(function () {
     // No click do botão de submit
     $('#btn_submit').click(function () {
         // Recebe os dados do formulário
         var valorTd = $('.class_da_td').text();
         var valorTd2 = $('.class_da_td2').text();
         // Envia a requisição ajax
         $.ajax({
             url: "ajax/form.php", // Arquivo php que vai receber os dados
             data: { // Recebe os dados das td´s e passa em um json
             valorTd: valorTd,
             valorTd2: valorTd2,
             },
             global: false,
             type: "POST",
             contentType: "application/x-www-form-urlencoded;charset=utf-8",
             dataType: "html",
             success: function (data) { // se tudo der certo mostra essa mensagem
                alert('Requisição realizada com sucesso!');
          },
        }).responseText;
    });
});

In the file form.php you would have more or less this structure:

<?php
    echo $_REQUEST['valortd'];
    echo $_REQUEST['valortd2'];
    // A partir disso podemos fazer o que for necessário com esses dados
    // Desde operações como salvar, apagar, editar, o que seja.
?>

Remembering this is just a small example. Many things have been abstracted to facilitate understanding.
