Post variables not sending

Hi Everyone,

I have a form that basically lets you select a specific date which I send using the post method. When I send it I get the error:

where month is the post variable I am trying to call. This error comes up three times for each of the POST variables I am trying to call. Below is my code:

The form:

<form action="calendar.php?action=date" method="POST">
                        <h2>Choose a date:
                                    <?php
                                    $cal_set = list_calendar();
                                    $output = "<select>\n";
                                    while($calendar = mysql_fetch_array($cal_set)){
                                        $output .="<option name=\"month\" value=\"".$calendar['id']."\"";
                                        if ($calendar['id'] == $month){ 
                                            $output .= " selected=\"selected\"";
                                        }
                                        $output .= ">".$calendar['month']."</option>\n";
                                    }
                                    $output .= "</select>\n";
                                
                                    $output .= "<select>\n";
                                    for ($i = 1; $i <= 31; $i++) {
                                        $output .="<option name=\"day\" value=\"".$i."\"";
                                        if ($i == $day){ 
                                            $output .= " selected=\"selected\"";
                                        }										
                                        $output .=">".$i."</option>\n";
                                    }
                                    $output .= " </select>\n";
                                    $output .= "<select>\n";
                                    for ($i = 0; $i <= 1; $i++) {
                                        $output .= "<option name=\"year\" value=\"".(date("Y")+$i)."\"";
                                        if ((date("Y")+$i) == $year){ 
                                            $output .= " selected=\"selected\"";
                                        }
                                        $output .= ">".(date("Y")+$i)."</option>\n";
                                    }
                                    $output .= "</select>\n";
                                    echo $output;
                                    ?>
                                    <input type="submit" value="Go" name="ToDate" /></h2>
                            </form>

PHP:

The code where I check if the form has been submitted is at the top of the page:

<?php
    require_once('includes\connection.php');
    require_once('includes\functions.php');
    $public = TRUE;

     if (isset($_POST['ToDate'])){
        $month = $_POST['month'];
        $day = $_POST['day'];
        $year = $_POST['year'];
        die("DONE");
     }else{
        $month = date("n");
        $day = date("j");
        $year = date("Y");
     }
     $timestamp = create_timestamp($month, $day, $year);
?>

Any help is appreciated. Thanks in advance!

 

It's because there is no such index called 'month', in $_POST array. Please re-check your HTML Form Code. You don't have an input field defined with name="month". 'name' is a valid attribute of <select> tag, not the <option> tag. So change form code as follows:

<form action="calendar.php?action=date" method="POST">
                        <h2>Choose a date:
                                    <?php
                                    $cal_set = list_calendar();
                                    $output = "<select name=\"month\">\n";
                                    while($calendar = mysql_fetch_array($cal_set)){
                                        $output .="<option value=\"".$calendar['id']."\"";
                                        if ($calendar['id'] == $month){ 
                                            $output .= " selected=\"selected\"";
                                        }
                                        $output .= ">".$calendar['month']."</option>\n";
                                    }
                                    $output .= "</select>\n";
                                
                                    $output .= "<select name=\"day\">\n";
                                    for ($i = 1; $i <= 31; $i++) {
                                        $output .="<option value=\"".$i."\"";
                                        if ($i == $day){ 
                                            $output .= " selected=\"selected\"";
                                        }                                       
                                        $output .=">".$i."</option>\n";
                                    }
                                    $output .= " </select>\n";
                                    $output .= "<select name=\"year\">\n";
                                    for ($i = 0; $i <= 1; $i++) {
                                        $output .= "<option value=\"".(date("Y")+$i)."\"";
                                        if ((date("Y")+$i) == $year){ 
                                            $output .= " selected=\"selected\"";
                                        }
                                        $output .= ">".(date("Y")+$i)."</option>\n";
                                    }
                                    $output .= "</select>\n";
                                    echo $output;
                                    ?>
                                    <input type="submit" value="Go" name="ToDate" /></h2>
                            </form>

Use this code and it'll work, I believe.

 

Thanks a ton. I didn't even notice that. It works perfect now.
