Include Ajax results in form submit

MC_Elemental

Hi, I'm really new with this whole php deal so I beg your patience if things aren't quite making sense ^_

I'm designing a site where users can select their province, city and have a bunch of checkboxes with options that they can select. I used Ajax to dynamically populate the City list box which has now got me stumped. I need to include the city in the final query to the DB; because the city list box is populated from an external page, the results aren't loaded inside the current form, only displayed (does that make sense?). Is there some additional code that I can use so that when I submit the full form it included the selected city?

Or is there a better way to do this that doesn't involve refreshing the page?

Thanks a bunch!

Do you have a URL to the page?

If it is displaying to the screen, it should appear when you submit the form in the $POST array as long as you have given the list box an id & name. 1 issue I have come across is that if you only use and id and not a name -- it doesn't recogonize it as a form field and will not include it in the $POST array.

I don't have a URL yet as I'm trying to get all the bugs worked out before I put it live. Can I copy the code in here without doing irreparable harm?

I'll give that a shot, I was using Get instead of post for the Ajax portion of the form, I'll switch it over to Post and name the list box and see how that goes. If it doesnt' work, I'll try and post the code here at least ^_

innerhtml is funny if you are using that. Doesn't compile to the DOM preoperly so doesn't get posted if I remember it correctly, just visible. Made that mistake a few times.

To check it you can use a DOM explorer/Inspector. Firefox has one as an install option, if it is there it will be under tools. IE 7 has a web developer thing as well in 7. Search by tag "input" and it will go through them. If it doesn't find it that is your answer and you will have to resort to DOM methods from XML/JSON.

Since this question is about getting data to PHP from the client, and not about what happens afterward, I'm moving this to the more appropriate forum.

It's in the nature of HTML that for a form field to be part of a form submission it must have a name. That's what the "name" attribute is for.

[ http://www.w3.org/TR/REC-html40/interact/forms.html#h-17.13.2 ] A successful control is "valid" for submission. Every successful control has its control name paired with its current value as part of the submitted form data set. A successful control must be defined within a FORM element and must have a control name.

Obviously, however, we can't really say what's wrong with the code without seeing it.

HaHa, I can't believe I didn't think to name the list box... that was exactly what the problem was...

Thanks a bunch!
