    Normally, if it’s PHP and normal Submit, you can do this $nome = isset( $_POST['nome'] )?$_POST['nome']:''; and in the form <input name ="nome" value="<?php echo htmlentities( $nome ); ?>">, as long as you send $_POST to the same page that generates the form

  • But I have to initialize the variable with null, right?

  • No need, see that the ternary of isset is already returning empty if you don’t have the post. Take advantage that there is no answer, click [Edit] and put your code in part PHP and HTML, which makes it easier to post an example.

  • however I will pass more data, beyond the name and I will play to a function that will bring a result of the database.

  • Anyway, you have to [Edit] explain the flow of data and preferably by a minimum example of code the way you are doing now, to facilitate who is to give answers. The essence is what I put in the comment, which is to fill the value with the information, regardless of where the data comes from
