I have the following excerpt:
<html>
<form name="sai_frm_incl_patr" method="post" action="sai_incl_peri_seri_patr.php">
<body>
<table border="0" width="100%">
<tr>
<td colspan="3" bgcolor="Silver" align="center">
<b><font face="arial" color="blue" size="2">Inclusão de Patrimônio e serial</font>
</td>
</tr>
<tr>
<td>
<input type="hidden" id="id_pat" name="w_patr_seri" value="aaaaa">
</td>
</tr>
</table>
</body>
</form>
</html>
And on the page that is receiving the data I do this:
<?php
$w_patr = trim($_POST['w_patr_seri']);
?>
But the variable does not contain any content! What must be the mistake? Or what am I doing wrong? '
