Good evening everyone, I'd like to know how to open a form whose fields are already filled in with user data (resulting from a search in the database), and it's up to him to only edit the information. I searched the internet and found a way, but it would be generating the HTML of the whole form via PHP's echo command; however I read that this is not a good programming practice ... is there any way to do it in a way that respects good practices?
How to open a screen with pre-filled form with PHP and HTML?

It would be interesting to have a value for a variable in the value attribute, so every time you load the data from the database you would assign the values. For example:
You would call the page passing the values in the request:
<?php
function __autoload($class) {
if (file_exists("../app.ado/{$class}.class.php")) {
include_once "../app.ado/{$class}.class.php";
}
}
// Verifica se exitem valores passados na requisição - A mesma página serve para cadastro e edição,
// quando é aberta sem nenhum valor passado é para cadastro, caso contrário é edição
if (empty($_REQUEST)) {
// Variáveis que estão referenciadas nas textbox
$id = "";
$nome = "";
$emailContato = "";
$idInstituicaoEnsino = "";
$tipo = "";
} else {
$id = $_REQUEST['id'];
$nome = $_REQUEST['nome'];
$emailContato = $_REQUEST['emailContato'];
$idInstituicaoEnsino = $_REQUEST['idInstituicaoEnsino'];
$tipo = $_REQUEST['tipo'];
}
?>
And then we have the html:
<form method="post" action="controller.php">
<table><!-- Campos de preenchimento-->
<!-- Identificação-->
<tr>
<td>
Identificação
</td>
<td>
<input type="text" name="_id"
value="<?= $id ?>"
placeholder="Id Numérico"
size="10" title="Numero que identifica o curso"/>
</td>
</tr>
<!--Nome-->
<tr>
<td>
Nome
</td>
<td>
<input type="text" name="_nome"
value="<?= $nome ?>"
placeholder="Nome do curso"
size="50" title="Nome do curso"/>
</td>
</tr> ... E assim por diante

The pretension to pre-fill information from an HTML form is actually very simple, even more using PHP.
<?php
$nome_html = htmlspecialchars( $nome );
$email_html = htmlspecialchars( $email );
?>
<form name="meuForm" method="post" id="formulario">
<label for="nome">Nome</label>
<input type="text"
class="input_text"
name="nome" id="name"
value="<?= $nome_html ?>" />
<label for="email">Email</label>
<input type="text"
class="input_text"
name="email" id="email"
value="<?= $email_html ?>" />
<input type="button"
class="button"
value="Enviar" />
</form>
Some tips:
<table> table structure to organize your form, prefer structure tableless , which make your code much more organized by separating design and organization into a CSS file.
