Hi again whit my problems !!!!!!!

In this code i put the java to show alert when user is blank or character invalid.

$form[registro] = '
          <form name="form"  action="?envio" onsubmit="return revisar_usuario() method="post">
          <table width="100%">
          <tr><td width="25%" align="right" valign="top">
             <b>Nombre:</b>
          <td width="75%">
             <input type="text" size="25" name="nombre" id="nick" malength="100"> <font color=red>*</font>
          <tr><td width="25%" align="right" valign="top">
             <b>E-mail:</b>
          <td width="75%">
             <input type="text" size="25" name="email" malength="100"> <font color=red>*</font>
		 <tr><td width="25%" align="right" valign="top">
             <b>Contraseña:</b>
          <td width="75%">
             <input type="password" size="25" name="contrasena" malength="100"> <font color=red>*</font>
          <tr><td width="25%" align="right" valign="top">
             <b>País:</b>
          <td width="75%">
            <input type="text" size="25" name="pais" malength="100">
          </table><br>

         <center><input type="submit" value="&nbsp;&nbsp;&nbsp;&nbsp;Enviar&nbsp;&nbsp;&nbsp;&nbsp;">
          <input type="reset" value="&nbsp;&nbsp;&nbsp;&nbsp;Borrar&nbsp;&nbsp;&nbsp;&nbsp;"></center>
          </form>¿ Perdiste tu Password ?<br>
		';

The java:

Code Select

function revisar_usuario() {
	document.form.nombre.value = document.form.nombre.value.replace(/^\s*|\s*$/g,'') ;
	document.form.contrasena.value = document.form.contrasena.value.replace(/^\s*|\s*$/g,'') ;
	if(document.form.nombre.value.length == 0) {
		alert('Debes escribir un nick') ;
		return false ;
	}
	if(document.form.contrasena.value.length == 0) {
		alert('Debes escribir una contraseña') ;
		return false ;
	}
}

Now, when I not write de username the form retur, don't show alert....

Hi again !.

When I create cookie, but show error.

Code Select

 Ingresado como das....
Warning: Cannot modify header information - headers already sent by (output started at /home/rulz/public_html/conf.php:31) in /home/rulz/public_html/usuarios.php on line 38

Warning: Cannot modify header information - headers already sent by (output started at /home/rulz/public_html/conf.php:31) in /home/rulz/public_html/usuarios.php on line 39

The code to make:

Quote 36if($contrasena == $row[contrasena]){
   37echo" Ingresado como $nombre....";
   38 setcookie('cmhipnombre',$nombre,time()+1296000);
   39 setcookie('cmhipcontrasena',$contrasena,time()+1296000);
}

In conf.php at line 31:

Quotefunction cabecera($seccion){
echo '
