Odd, _GET variable is missing from my form submission...

[xtiansimon]

I'm using a form element to alter (or not alter) a variable used to adjust the page layout. This is a basic PHP, MYSQL and CSS page. The form element is supposed to send the name of the form and the adjustment value.

The adjustment value is set with a select element. The form name is set with an invisible input element. The form is sent with an OnChange event in the select element. (oddly in my test case, below, this is working without the action parameter).

The trouble is the invisible input is not being set in the URL. To test what is going on I simplified the page removing the MYSQL data and replaced it with a print_r of the variable used to adjust the layout. I also removed all the content and CSS. What remains is the display of a variable, a pulldown, a variable, a pulldown, etc.

The test page performs perfectly, but the actual content page does not. The differences are:
-- The test page has no actual content from MYSQL, and instead only the variable;
-- Looking at the URL for the real page does it does not include the form name (from the hidden input) while the test does;
-- There is no CSS in the test page;
-- The URL of the test page is shorter;

Any ideas what could be happening?

PS. had a trouble with the post window, I hope this thread isn't repeated...

Hey.

Could you show us the three elements from the broken page, exactly like they appear in the browser? (Just the <form>, <input> and <select> elements should be fine.)

My first though was that you might have accidentally put the input outside the form, or forgotten to name it. Or that you set the form's method attribute to post instead of get. - I'm just guessing here. I need to see the code to be able to do any more than that.

Thanks for the speedy reply. I don't know what I did, but its fixed. Well, I do know what I did. I copied the form processing code *again* and all of the forms into another blank page. This time I removed all the comments, and extra spaces. And, I was more methodical while removing MYSQL bits, and anything using the MYSQL vars. (Such as when I use count() on the fetch_array() results. I simply commented the original code to the side and entered a hard value.)

Again the new page worked perfectly. Then I copied the entire lot back to the content page, reversed the comments, and this time it worked. I honestly don't know what I did to fix the situation. Though I do recall I specifically ensured the URL was reset to just the page (and removing the old urls _GET variables)--it was really long. Certainly this would cause the page to load the variables incorrectly on the first load; however, I tested several form select elements each time I made a correction (which is to say I didn't just load the page and cry foul). Each time I saw the print_r of the form array change the general data, but not include the specific form name from the invisible input.

I can only conclude my code practices were sloppy and I put in a foul line (that amazingly also didn't cause an error) or I was somehow stuck in some unknown loop that would not allow the form to submit its full set of _GET vars...? More experience programming with _GET is necessary before I'll be sure.

Again thanks for the help.
