Resulta que tengo un formulario. Quiero que haya un campo de confirmación del primero (nit), para asegurarme de que el registrante ingrese bien ese dato, y si lo escribio mal obviamente no deje enviar el formulario y le idique que los vuelva a escribir.
Aqui esta mi formulario:
Código PHP:
<?php require_once('Connections/segurodb.php'); ?>
<?php
///////Configuración/////
$mail_destinatario = '@';
///////Fin configuración//
if (isset ($_POST['Grabar'])) {
$headers .= "From: ".$_POST['empresa']. "";
if ( mail ($mail_destinatario, $_POST['email'], "Nit : ".$_POST['nit']." Telefono: ".stripcslashes ($_POST['telefono'])." Empresa : ".stripcslashes ($_POST['empresa']), $headers )) echo '
'; }
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "")
{
$theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;
$theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);
switch ($theType) {
case "text":
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;
case "long":
case "int":
$theValue = ($theValue != "") ? intval($theValue) : "NULL";
break;
case "double":
$theValue = ($theValue != "") ? "'" . doubleval($theValue) . "'" : "NULL";
break;
case "date":
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;
case "defined":
$theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
break;
}
return $theValue;
}
}
// *** Redirect if username exists
$MM_flag="MM_insert";
if (isset($_POST[$MM_flag])) {
$MM_dupKeyRedirect="yaexiste.php";
$loginUsername = $_POST['nit'];
$LoginRS__query = sprintf("SELECT nit FROM registro WHERE nit=%s", GetSQLValueString($loginUsername, "int"));
mysql_select_db($database_segurodb, $segurodb);
$LoginRS=mysql_query($LoginRS__query, $segurodb) or die(mysql_error());
$loginFoundUser = mysql_num_rows($LoginRS);
//if there is a row in the database, the username was found - can not add the requested username
if($loginFoundUser){
$MM_qsChar = "?";
//append the username to the redirect page
if (substr_count($MM_dupKeyRedirect,"?") >=1) $MM_qsChar = "&";
$MM_dupKeyRedirect = $MM_dupKeyRedirect . $MM_qsChar ."requsername=".$loginUsername;
header ("Location: $MM_dupKeyRedirect");
exit;
}
}
$editFormAction = $_SERVER['PHP_SELF'];
if (isset($_SERVER['QUERY_STRING'])) {
$editFormAction .= "?" . htmlentities($_SERVER['QUERY_STRING']);
}
if ((isset($_POST["MM_insert"])) && ($_POST["MM_insert"] == "form1")) {
$insertSQL = sprintf("INSERT INTO registro (nit, email, telefono, empresa) VALUES (%s, %s, %s, %s)",
GetSQLValueString($_POST['nit'], "text"),
GetSQLValueString($_POST['email'], "text"),
GetSQLValueString($_POST['telefono'], "text"),
GetSQLValueString($_POST['empresa'], "text"));
mysql_select_db($database_segurodb, $segurodb);
$Result1 = mysql_query($insertSQL, $segurodb) or die(mysql_error());
$insertGoTo = "gracias.php";
if (isset($_SERVER['QUERY_STRING'])) {
$insertGoTo .= (strpos($insertGoTo, '?')) ? "&" : "?";
$insertGoTo .= $_SERVER['QUERY_STRING'];
}
header(sprintf("Location: %s", $insertGoTo));
}
mysql_select_db($database_segurodb, $segurodb);
$query_rc_registro = "SELECT * FROM registro";
$rc_registro = mysql_query($query_rc_registro, $segurodb) or die(mysql_error());
$row_rc_registro = mysql_fetch_assoc($rc_registro);
$totalRows_rc_registro = mysql_num_rows($rc_registro);
