two (image-) submit buttons

[Anon]

hello.

big problem. tried for hours:

I have to use a form with two buttons. both have to be images.

if the first is pressed, the form-data is processed in a following modify.php, saved into a database and forwarded to page 1.
if the second button is pressed, the form data is handled in the same way, but i will be forwarded to page 2.

but how do i get a value to the php, which identifies which button i have pressed?

the problem:
i heared that graphical buttons are allways submit-buttons. adding value='1' and value='2' and different names did not result in the fact, that i could access it via php.
is there a way to use javascript to send the form-data and check and send which submit button is pressed?

i found:

submit buttons aren't that special, they just send a name and value like anything else :

<input type="submit" name="fruit" value="apple">
<input type="submit" name="fruit" value="banana">

Clicking the first will produce $fruit = 'apple' and the second will create $fruit = 'banana' and check accordingly :

if ($fruit == 'apple') {
echo 'you clicked on apple button';
} ------------------

but also this parameter is not accassible in the php script. I heard that submit buttons (and image-buttons) couldn't have own values to submit. is that right?

I also tried to access the koordinates (sub.x & sub.y) of the image click to process them. but also these data isn't submitted to the php.

And it is not the fault of netscape 4.x - also mozilla, konqueror and opera act the same.

thank you for help

In general, I've learned that two submit buttons in the same form are a bad thing. Is there any way you can have two separate forms with two separate submit buttons? e.g.

<FORM name="form1">
<BUTTON type="submit">submit</BUTTON>
</FORM>

<FORM name="form2">
<BUTTON type="submit">submit2</BUTTON>
</FORM>

btw - php DOES pass the X and Y values along, you are just looking for the wrong thing. I forget the exact syntax, but you need to replace the dot with an underscore and you should find what you're looking for.

Why don't you try to send the submit to a javascript function which appends something like ?page=page2.html to the submit url? Then you could have your modify.php get the page url from the query string.

input type="image" butto sends only name + the coordinates of the click as value
so value="something" is ignored
so you hare to change the name of the buttons

example:
<form action="" method=post>
<input type="text" name="txt" value="">
<input type="image" name="img1" src="b.gif">
<input type="image" name="img2" src="a.gif">
</form>

if(isset($img1.x)){
do_first();
}
elseif(isset($img2.x)){
do_second();
}

if(isset($img1.x)){
do_first();
}
elseif(isset($img2.x)){
do_second();
}

The small correction: there has to be an underscore, not a point:
$img1_x

Thank you all!!

by the way: I'm happy!
