I’m new to web programming, but I can’t find the error. I have a index.php, where there are 3 inputs for research, by code, Cpf or name.

After on the same page is shown the result in the form of link by found code of the search. this link directs on resultcontrato.php, where details about this code. In this resultcontrato.php has a Ubmit where directs to the page index.php again, that’s where the error described below comes in.

Index.php

Check that the variable was created before setting the variable for example.

session_start();

$vlremp=(isset($_POST['selemp'])) ? $_POST['selemp'] : '';

$_SESSION['selemp'] = (isset($_POST['selemp'])) ? $_POST['selemp'] : '';

if it was not created it receives a temporary value

  • Good morning Felipe, not she was created after passing through the Forms.
