  • Pdo get column names
    • ]]>     Beware when posting data from a multiple select through ajax. You can’t send an array with a Prototype ajax call.

    expl.

    function postmydata(){
    new Ajax.Request(‘data.php’,
    {
    method:’post’,
    parameters: {selectdata: $F(‘myselect’)},
    onSuccess: function(transport){
    var response = transport.responseText || alert(“couldn’t add data”);
    $(‘mydiv’).update(response);
    },
    onFailure: function(){ $(‘mydiv’).update(‘error’); }
    });
    }

    This won’t work. Your php page will not get an array.

    Solution

    replace the parameter part with:
    parameters: {selectdata: $F(‘myselect’).join(“,”)}, // this will send a comma seperated string
    In your php code use:
    $myselect = = explode(‘,’,$_POST['selectdata']);
