multiple image submit button problems

[Ryan]

I currently have two image submit buttons. The code generated looks like
so:

<input type="image" src="button_in_ cart.gif" border="0" alt="Add"
title="Add" name="btn_cart" value="buy">
<input type="image" src="modify.gif " border="0" alt="modify"
title="modify" name="btn_modif y" value="modify">

In mozilla everything works great, but in Konqueror and MSIE the if
statement I'm using to detect which button was press does not work.

if (isset($HTTP_PO ST_VARS['btn_cart'])){ do stuff }

Does anyone know how to fix this without resorting to javascript?


thanx

This could be a good start:

<pre><?
print_r($_POST) ;
?>/pre>

Where are you checking 'btn_modify'? The line above only checks
'btn_cart'

My preferred method would be:-

<input type="image" src="button_in_ cart.gif" border="0" alt="Add"
title="Add" name="action" value="buy">
<input type="image" src="modify.gif " border="0" alt="modify"
title="modify" name="action" value="modify">


if ($action == "buy") {

// do buy bit here

}
elseif ($action == "modify") {

// do modify bit here

}

Re: multiple image submit button problems

Wouldn't it make more sense to use the same name for both buttons?

<input type="image" src="button_in_ cart.gif" border="0" alt="Add"
title="Add" name="btn_actio n" value="buy">
<input type="image" src="modify.gif " border="0" alt="modify"
title="modify" name="btn_actio n" value="modify">

if($_POST['btn_action'] == 'buy') ...

else if($_POST['btn_action'] == 'modify') ...

Tried that, works fine in Mozilla but in Konqueror and Explorer it still
does not work.
Perhaps there is some bad html elsewhere that is messing things up. I'll
look for those errors when I get a chance.

Re: multiple image submit button problems

Sometimes the posted data does not have the value content of submit
button.
For example if the focus is in Inputbox and you press "enter" key. In
this case the first submit button will have focus.

So whatever you write in name, you need check the second submit button
in your if condition.

eg:

if(!empty($_POS T))
{
// Form Posted

if(isset($_POST['second_button_ name']))
/*
You can code this way if name is same for both button
if(isset($_POST['button_name'])
&& $_POST['button_name'] == "second_button_ value")
*/
{
// Second button clicked

}
else
{
// First button clicked

}
}

Strange, it works fine here using Nutscrape, IE, Opera & kmeleon.
Have you tried an 'echo $action;' before the 'if' to make sur you are
picking up the variable?

Maybe add

if (!$action) {echo "NO VARIABLE PASSED";}

elseif ($action etc....

I don't get it, the image button isn't getting passed into the form post
data. It isn't set, it isn't showing up at all, only works in mozilla.
Anyone offlist want to have a go at the html I'm generating?

Email me a copy of your script and I'll have a look at it for you.

The submit button works, but in IE, the value attribute is ignored
