Multiple submit buttons php different actions

Question

I have a website started where I want to have 2 separate submit buttons, one of which will take data entered and do some calculations to it to display on the same screen. I've got this successfully working with:

<form id="form1" name="form1" method="post" onsubmit="" onreset="" action="programname.php">
<input type="submit" name="calc" value="Find Angle">

and then I use:

if (!isset($_POST['submit'])){
Do actions, display calculations}

Now I want a second submit button that still grabs the data they entered but then goes to a different address. Is there an elegant way to do this?

Answer 1

You can change the form action by using formaction="page1.php" in button property .

<form id="form1" name="form1" method="post" onsubmit="" onreset="" action="programname.php">
    <input type="submit" name="calc" value="Find Angle">

    <input type="button" type="submit" formaction="page1.php">Action 0</button>
    <input type="button" type="submit" formaction="page2.php">Action 1</button>
</form>

Note: The formaction attribute of the button tag is not supported in Internet Explorer 9 and earlier versions.

The best way to deal with multiple submit button is using switch case in action script

<form action="demo_form.php" method="get">

    Choose your favorite subject:

    <button name="subject" type="submit" value="html">HTML</button>
    <button name="subject" type="submit" value="css">CSS</button>
    <button name="subject" type="submit" value="javascript">Java Script</button>
    <button name="subject" type="submit" value="jquery">jQuery</button>

</form>

Action / Server Side script:

demo_form.php

<?php

switch($_REQUEST['subject']) {

    case 'html': //action for html here
                break;

    case 'css': //action for css here
                break;

    case 'javascript': //action for javascript here
                        break;

    case 'jquery': //action for jquery here
                    break;
}

?>

You could add an onclick method to the new submit button that will change the action of the form and then submit it.

<script type="text/javascript">
  function submitForm(action) {
    var form = document.getElementById('form1');
    form.action = action;
    form.submit();
  }
</script>

...

<form id="form1">
  <!-- ... -->
  <input type="button" onclick="submitForm('page1.php')" value="submit 1" />
  <input type="button" onclick="submitForm('page2.php')" value="submit 2" />
</form>
