Data Validation

[pavmoxo]

I have the next PHP code:

<select name="day" id="day" tabindex="3">
                                      <?php
                                        for($n=1; $n <=31; $n++)
                                        { 
                                    ?>
                                    <option value="<? echo $n ?>"><? echo $n ?></option>
                                    <?
                                        }
                                    ?>
                                    
                            </select>
                  
                                  <select name="month" id="month"  tabindex="3">
                                    <?php
                                        for($n=1; $n <=12; $n++)
                                        { 
                                    ?>
                                    <option value="<? echo $n ?>"><? echo $n ?></option>
                                    <?
                                        }
                                    ?>
                                  </select>
                                  
                                  
                                  <select name="year" id="year" tabindex="3">
                                   
                                    <?php for($i=0;$i<3;$i++) { ?>
                                      <option><?php echo(date('Y') - $i); ?></option>
                                    <?php } ?>

                                  </select>

You have this in a form, yes?

The user submits the form, yes?

Next page, use php to check what was chosen. (if....)
