Dropdown menu adding wrong value to database

[larsy87]

Hey guys,

I was recently given the task of fixing a PHP application page. I don't know PHP, but I do have extensive knowledge of java, js and c/c#/c++.

That being said, I'm at a loss to fix my problem. The PHP page is a registration form with names, birthdays, etc, all your standard stuff.

When you fill out the birthday and submit it, the birth day is almost always 1 - sometimes it's 2(very infrequently) and sometimes it will roll back to 31(no provision in code for different lengths of the months).

I've attached the code for the birth day drop down. I attempted to add the debug lines and neither of them worked for me. The birth month and birth year code all works as it should, only problem being with the day.

Any insight offered would be greatly appreciated.

                echo "<select size='1' name='child_dob_day[".$child."]'>";
                for ($day=1;$day<=31;$day++)
                {
                        echo "<option value='".$day."'";
                        if ($form->values["child_dob_day"][$child] == $day)
                                echo " selected";
                        echo ">".$day."</option>";
                }
                echo "</select>";

check your html source if the select box is populated properly

I'm not sure what you mean...the days are added to the drop down by the for loop, how else would the box be populated?

out of interest, what kind of object is $form?

Look at the source of your page. That is, right-click -> view source. You'll see the rendered HTML. Post it here, and from there we might be able to deduce the problem more efficiently.

@Dormilich
it could be a instance of a form object, some (including me) creates form objects
from a class (custom made), especially when dealing with ajax so we can send the form values as a json object and map with the form object, im not sure may be some frameworks also support this facility.
