How to check if 2 different buttons have been hit?

[georgianna]

hello,

this is the problem I have been facing. I have 2 different buttons in a single form that when they are hit I want them to do 2 different things.

They are not submit buttons, because I don't want to submit the form always, but only when the checkbox of the form is checked. Otherwise, if the checkbox is unchecked, the form will not be submitted, but instead an alert message will be displayed to the user.

The problem is that I haven't found a way so far to see which button has been hit and execute different things in each case. The isset function doesn't work with plain buttons that are not submit buttons. I would like to note that these things that I want to be executed are in the same page as the form.

Here is a short description of the code (testpage1.php):

for the form:

   print "<form name=\"main_form\"   method=\"POST\">";
print "<input type=\"checkbox\" name=\"fieldname\" value=\"anyvalue\">";
print "<input type=\"button\" name=\"submit1\" value=\"button1\" onClick='javascript:checkbutton1();'>";
print "<input type=\"button\" name=\"submit2\" value=\"button2\" onClick='javascript:checkbutton2();'>";
 print "</form>";

for the Javascript function:

echo '<script language="JavaScript">


            function checkbutton1()
            {
             if ((document.forms["main_form"].fieldname[0].checked==1))
             {

                  document.forms["main_form"].action="testpage1.php";
                  document.forms["main_form"].submit();
             }
             else
             {
                  alert ("Please check the value for which you want to find the exhibits");
             }
            }

            function checkbutton2()
            {
            if ((document.forms["main_form"].fieldname[0].checked==1))
             {

               document.forms["main_form"].action="testpage1.php";
               document.forms["main_form"].submit();
             }
             else
             {
               alert ("Please check the value for which you want to find the categories");
             }
          }


           </script>';

Now if in testpage1.php in the beggining I write:

if (isset($submit1))
{

//   do something

}

if (isset($submit2))
{

//   do something else

}

it doesn't work! Does anyone have an idea that could help me?

Thanks,

Georgianna

I don't know if the javascript code is working but i can give you some ideas:

-try to use isset ($_POST['submit1']) instead of just $submit1. You may want to check if register_globals is enabled or not in your php.ini
- if none of this works. You can also try in your javascript code:

 document.forms["main_form"].action="testpage1.php?submit1=true";
 document.forms["main_form"].submit();

// and

document.forms["main_form"].action="testpage1.php?submit2=true";
 document.forms["main_form"].submit();

hope it helps.

You really helped me resolve the problem that I had with the second solution that you told me!

Thanks a lot!

An easier way to do this is like this:

1). Do your button somewhat like this. EXAMPLE: <input type="button" name="submit1" value="Button">

2). Leave your javascript alone.

3). give each button a name.

4). Use below code for the page.

//check to see if submit1 button was pressed
if($submit1)
{
//do action for the submit 1 button
}

//check to see if submit2 button was pressed
if($submit2)
{
//do action for the submit 2 button
}

5). Make the form tags like this:

<form action="<? echo "$PHP_SELF";?>" method="post" name="form">

I think you get the general idea.
