Let’s imagine a table, called entity, already created in your bank. So, we have:
+-----------------------------------------------+
|id_entidade integer primary key auto_increment |
|-----------------------------------------------|
|nome varchar(50) |
+-----------------------------------------------+
This should be for example. Now we need the form to register users, let’s call form_usuario.php:
<form action="set_user.php" method="post">
<div class="form-body">
<h3 class="box-title"><i class="icon-people p-r-10"></i>Dados Principais</h3>
<hr>
<div class="row">
<div class="col-md-6">
<div class="form-group">
<label class="control-label">*Nome</label>
<input type="text" id="nome" name="nome" class="form-control" placeholder="">
</div>
</div>
<!--/span-->
<div class="col-md-6">
<div class="form-group">
<label class="control-label">Sobrenome</label>
<input type="text" id="sobrenome" name="sobrenome" class="form-control" placeholder="">
</div>
</div>
<!--/span-->
</div>
<div>
<!--Campo para redirecionar automaticamente caso queira salvar novo documento-->
<input type="checkbox" name="novo_documento"> Salvar novo documento
</div>
<input type="submit">
</form>
Shows the next value of id_entity It’s quiet, but it’s susceptible to writing, because there’s no guarantee that anyone will try to register simultaneously. Anyway I left the function to do (commented). So let’s go to the page set_user.php:
<?php
cadastrarUsuario();
//registra novo usuario
function cadastrarUsuario(){
$conexao = mysqli_connect('127.0.0.1', 'root', '', 'teste');
$status = mysqli_query($conexao,
"insert into entidade (nome) values ('". $_POST['nome'] . "')");
if($status === true){
//redireciona para o formulario de cadastrar documento
if(isset($_POST['novo_documento'])){
ob_get_clean();
ob_start();
$ultimo_id = mysqli_insert_id($conexao);
require_once __DIR__ . '/salvar_documento.php';
ob_end_flush();
}else{
echo 'salvo com sucesso';
}
}
else{
echo 'erro ao salvar: ' . mysqli_error($conexao);
}
}
//função para encontrar o proximo id_entidade na tabela entidade
function proximoId(){
//dados de conexão com o banco, na ordem, host, usuario, senha, e nome do banco utilizado
$conexao = mysqli_connect('127.0.0.1', 'root', '', 'teste');
//lista informações da tabela entidade (estrutura), uma delas refere-se ao proximo auto_increment
$tabela_entidade = mysqli_query($conexao, "SHOW TABLE STATUS LIKE 'entidade'");
$proximo_id = mysqli_fetch_assoc($tabela_entidade)['Auto_increment'];
return $proximo_id;
}
On this page is obtained the id of the last inserted entity (for when to insert new document). It also has the functions ob_get_clean(),
ob_start(), ob_end_flush which are used to "print" the inclusion output of the file salvar_documento.php (all html content).
And finally the file salvar_documento.php, can "recognize" the variable $ultimo_id
, because it was included (require) within the set_user.php file (where the variable was declared $ultimo_id
). And a form was added, with a hidden field representing the id of the created entity. It was like this:
<!--Outro formulario-->
<form action="algumapagina.php" method="post">
<div class="form-body">
<h3 class="box-title"><i class="icon-people p-r-10"></i>Salvar documento</h3>
<hr>
<!--Recupera o id da ultima entidade salva-->
<label>O id da entidade criada é <?php echo $ultimo_id; ?></label>
<input type="hidden" name="id_entidade" value="<?php echo $ultimo_id; ?>">
<div class="row">
<div class="col-md-6">
<div class="form-group">
<label class="control-label">*Nome</label>
<input type="text" id="nome" name="nome" class="form-control" placeholder="">
</div>
</div>
<!--/span-->
<div class="col-md-6">
<div class="form-group">
<label class="control-label">Sobrenome</label>
<input type="text" id="sobrenome" name="sobrenome" class="form-control" placeholder="">
</div>
</div>
<!--/span-->
</div>
</form>
Suppose all files are in the same directory.
For a reference of the functions mysqli_* see at w3c.
It remains to put what has already been done (source code, not everything, but the necessary). The way it is is too subjective to answer properly.

I put the code I made so far.

Robson if your code so far is NO gets complicated. Your question is very broad as there are several ways to do it. I advise you to research more about php and try to perform this application. Search about php

php, it will direct the user to another environment if necessary.– Andrei Coelho
