Two submit buttons in one form

Question

I have two submit buttons in a form. How do I determine which one was hit serverside?

Answer 1

<form method="post">
<input type="hidden" name="id" value="'.$id.'" readonly="readonly"/>'; //any value to post PHP
<input type='submit' name='update' value='update' formAction='updateCars.php'/>
<input type='submit' name='delete' value='delete' formAction='sqlDelete.php'/>
</form>

Answer 2

I think you should be able to read the name/value in your GET array. I think that the button that wasn't clicked wont appear in that list.

Answer 3

This is extremely easy to test

<form action="" method="get">

<input type="submit" name="sb" value="One">
<input type="submit" name="sb" value="Two">
<input type="submit" name="sb" value="Three">

</form>

Just put that in an HTML page, click the buttons, and look at the URL

Answer 4

The best way to deal with multiple submit button is using switch case in server 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>

server code/server script - where you are submitting the form:

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;
}

?>

Answer 5

Simple you can change the action of form on different submit buttons Click.

Try this in document.Ready

$(".acceptOffer").click(function () {
       $("form").attr("action", "/Managers/SubdomainTransactions");
});

$(".declineOffer").click(function () {
       $("form").attr("action", "/Sales/SubdomainTransactions");
});

Answer 6

You can also use a href attribute and send a get with the value appended for each button. But the form wouldn't be required then

href="/SubmitForm?action=delete"
href="/SubmitForm?action=save"
