Re: form question

OK, lets see what I did. I put values to all the checkboxes (unique values). I put quotes at all the values. I submit the form and all I get is an empty array. Why is it? I've done everything you people told me, and I find no reason for this to happen. The page looks like this: <html> <body> <form action="prueba-resultado.php" method="post"> <? echo(printf("<input type=\"checkbox\" checked name=\"ar_pru[]\" value=\"1\"><BR> \n")); echo(printf("<input type=\"checkbox\" checked name=\"ar_pru[]\" value=\"2\"><BR> \n")); echo(printf("<input type=\"checkbox\" checked name=\"ar_pru[]\" value=\"3\"><BR> \n")); echo(printf("<input type=\"submit\" value=\"Go!\"> \n")); ?> </form> </body> </html> and the script prueba-resultado.php looks like this: <html> <body> <? if (isset($ar_pru)){ echo "The variable is set.<br>\n"; }else{ echo "The variable is not set. <br> \n"; die; } if (! key($ar_pru)){ echo "The array is empty.<br>\n"; } for ($i=1;key($ar_pru);$i++){ echo(sprintf("La variable es %s, y su valor %s \n <br> \n",$i, $ar_pru[$i])); next($ar_pru); } ?> </body> </html> and the output on the navigator is this: <html> <body> The variable is set.<br> The array is empty.<br> </body> </html> Any ideas on this?
