2 submits buttons for a form.

1,168 Recognized Expert Top Contributor

Hey guys,
Well what I want is to have one form, but two submit buttons. Depending on which submit button is pressed, different code will run.

Here is a short version of my form:
[HTML]<form action="myform.php" method="POST">
<input name="var1" type="text" value="0" size="7" maxlength="6" />
<input name="var2" type="text" value="0" size="7" maxlength="6" />
<input name="var3" type="text" value="0" size="7" maxlength="6" />
<input name="var4" type="text" value="0" size="7" maxlength="6" />
<input name="recruit" type="submit" value="Recruit" />
<input name="disband" type="submit" value="Disband" />
</form>
[/HTML]

The php check:
[PHP]if ( $_SERVER['REQUEST_METHOD'] == 'POST' && isset($_POST['var1']) && isset($_POST['var2']) && isset($_POST['var3']) && isset($_POST['var4']) )
{ //do stuff
}[/PHP]

So can I add something like && $_submit_name == 'recruit' ???

Also, I know this is a php forum, but do you also know the javascript offhand:
[HTML]if ( document.myform.var1.value == "" && document.myform.var2.value == "" && document.myform.var3.value == "" && document.myform.var4.value == "" )[/HTML]

I don't quite understand your coding.
You check if your text inputs are set, but theyre always set.
Also, i dont understand the usefullness of 'request_method'?

Anyway, how i would do this is:
[php]
if(isset($_POST['recruit']))
{
# do recruit stuff
}
elseif(isset($_POST['disband']))
{
# do disband stuff
}
else
{
# nothing submitted
}
[/php]

use javascript submit()
each button onclick to send different data to the server

I cannot see how javascript could help here and work better than php.

Just take the example markusn00b showed and you'll be fine. JS just clouds this dicusssion.

Cheers markus, yeah you're right about the request_method, it was an old form I was reformatting, forgot to take it out. I will try your code when I get home.

I am concerned about your question about my text inputs...
I have a few chunks of code to { do stuff } so when the form submits information to that file, it will send only the variables contained in that form. So by checking isset() I thought what I was doing was making sure it was the correct information for that function.

ie.
<body>
form1 {var1 var2 var3}
form2 {var4 var5 var6}
</body>

do_stuff.php {form1_function form2_function}

If I submit form1, form1_function checks if var1, 2 and 3 are set (which they are) before it runs, but when the reader gets down to form2_function, var4, 5 and 6 are not set (because I only submitted form1) so it will not run.
Is this not how it works?

Oh, i see.

Well, you can bypass all that with using the way i suggested in my prev. post.

Regards :)

ps: i thought you were checking that the inputs had a value and all of them had to have a value before the IF statement would run - this is flawed because text inputs' are always passed in a form, empty or not.

</form>
[/HTML]

Another way I do it, is the NAME of the buttons are the same but the values are not, so i just get the value of the button and run appropriate action.

[PHP]

<input type="submit" name="pageAction" value="Action One" />
<input type="submit" name="pageAction" value="Action Two" />

[/PHP]

then on php side

[PHP]

if($_POST['pageAction'] == "Action One")
{
// do something
}
else if ($_POST['pageAction'] == "Action Two")
{
// do something else
}

[/PHP]

Anybody know which way is better? I'll change the way markus is doin it if that's better.

There won't be any significant difference; there's just more writing in your way :P

I know this is a php forum but do you (markus or anyone else) know how to do the equivalent in javascript?

I can give it a shot:

Expand|Select|Wrap|Line Numbers

 
function doForm(buttonPressed)

{

    if(buttonPressed == "Recruit")

    {

        // do something

        alert(buttonPressed);

    }

    else // 'disband' was pressed

    {

        # do something

        alert(buttonPressed);

    }

}

Expand|Select|Wrap|Line Numbers

 
<form name="someForm" method="post" action="page.php">

 <input type="text" name=" ...
 
 <input type="submit" name="recruit" onclick="doForm(this.value)" value="recruit" />
 
   <!-- you get the idea.. //-->

I'm not expert with javascript though, so maybe you should ask over there?

Sounds good, I will give it a go, but make a post... "OVER THERE"... on the other side (excuse the pun).
