[Yusdaniel Rodriguez Espinosa]

Hello to everyone.

I want to clean a field from my Data Base in MySQL from a button. But I don't know how 
i can create a button in PHP, the funtion of button is TRUNCATE TABLE(Table).

I have a form in HTML but hi don't work because when I press the button he don't do 
anything, but when i press the button submit he work I don't know way!!!

Here are the Form HTML Code:

<FORM Name="Form1" METHOD="post" >
    Nick : <INPUT TYPE="text" NAME="nick" SIZE=20 MAXLENGTH=20>
    <BR>
    Email: <INPUT TYPE="text" NAME="email" SIZE=28 MAXLENGTH=100>
    <BR>
    Password: <INPUT TYPE="password" NAME="password" SIZE=28 MAXLENGTH=20>
    <BR>
    Nombre: <INPUT TYPE="text" NAME="nombre" SIZE=28 MAXLENGTH=255>
    <BR>
    <INPUT TYPE="submit" CLASS="boton" VALUE="Registrar">
    <INPUT TYPE="reset" name="Submit" value="Restablecer">
    <INPUT TYPE="button" name="CleanBD" value="Limpiar BD" onClick="<?Limpiar()?>" >
</FORM>

and here are the code in PHP:

function Limpiar() {
    $servidor = "localhost" ;
    $usuario = "usuario" ;
    $contrasena = "password" ;
    $basededatos = "bd" ;
    $conectar = mysql_connect($servidor, $usuario, $contrasena);
    mysql_select_db($basededatos,$conectar) ; 
    $Limpiar = "Truncate table bd";
    mysql_query($Limpiar);
}
