input type=image and server config

sneakyimp

dig this:

                                          <input type="image" src="../../../images/query-round-location.gif" name="n_page" value="query_loc.php" width="112" height="26" border="0">

a coder friend of mine has written me some code...a single form might have 8 or 10 different submit images, each one of which would submit the form and lead to one of 8 or 10 different pages.

in other words, he wrote multiple submit buttons to store the current form and let the user move on to the next form of their choice.

my question involves the values that show up in $_POST. the value of the submit buttons (value="query_loc.php" in the above example) is totally ignored and i get post values for the X and Y values depending on where the user clicked.

is this the way php always behaves? i have no visiblity whatsoever to the VALUE of the image input. i can see ways around it...giving the submit buttons different names, etc. but it seems pretty involved and i don't want to insult my friend because my server config is screwy or something.

can anyone tell me more about submit images and php _post vars?

sumit image always gives x & y as the values.

you may have different name of the submit button. other solution is to have one big image.depending on upon where the user clicks on the image (using the x & y components, that come), appropriate page is loaded.

I'm not clear on your question actually...you get the value of x or y where?

However, I use image submit buttons...many of them on some pages and this has always worked for me...perhaps this is what you are looking for?

Your submit button would still have a normal name like:

... name='submit-me' ...

But you capture the results this way...

if (isset($_POST[$submit-me_x])) {

thanks for the response....

yes i understand that this submit image

will return values here:

$POST['foo_x']
$POST['foo_y']

i understand why that is....in case you have a clickable image map or something.

my question was whether or not the VALUE i have attached to the submit button (above just for a lark i assigned it "SUPER_IMPORTANT_MAYBE") is ever passed IN ADDITION to the x and y values.

if not, it's not critical. I was just wondering if I could adjust a server config or something and also get that value.

Ah, I see...

No...you would need a hidden field to grab that...

type=hidden name=whatever value=$PHP_SELF or value=thepage.php

voila...
