Two Submit Buttons in Forms - El Forum - 11-10-2008

I have a "form" that requires the user to accept or decline a request. I tried using $_POST with an if statement, but all that did was cause the CI scripts to think that the name of the button was a variable. How would I do something like this?
Example:
<form action='$_SERVER['PHP_SELF']' method='POST'>
<input type='submit' name='accept' value='Accept'>
<input type='submit' name='decline' value='Decline'>
</form>

This is "only" possible in asp.net.
Otherwise you have to do or:
<form action="<action>" method="post">
<input type="submit" name="accept" value="Accept" />
</form>
<form action="<action>" method="post">
<input type="submit" name="decline" value="Decline" />
</form>
OR:
<form action="$_SERVER[‘PHP_SELF’]" method="POST">
<input type="submit" name="accept" value="Accept">
<input type="submit" name="decline" value="Decline">
<input type="hidden" name="action" id="action" value="" />
</form>

Not true. I've done it with regular PHP before I started using code igniter.

Interesting, that is something I haven't tried so far.
So what do you want to do exactly ?
If you press accept $_POST = array('accept' => 'Accept'); otherwise $_POST = array('decline' => 'Decline');

Something like this:
if(!($_POST['accept']) || ($_POST['decline'])){
load form
} else {
perform action
}
Basically if neither of the buttons are pressed, the form is submitted. If one of them is pressed, a function is performed that will determine which one is pressed and will go from there.
Edit: Sorry, if neither of the buttons are pressed, the form is displayed, not submitted.

Ah!
Not exactly in the best practices but I would do something similar to :
if(!isset($_POST['accept']) or !isset($_POST['decline']))
$this->load->view('the_form');
else
// do the stuff
Note that to access the $_POST you need to set $config['enable_query_strings'] = TRUE; in /system/application/config/config.php otherwise you can access your post arrray via $this->input->post(<name>);

in ci you can do this
in controller
Code:
<?php
function show_form()
{
$this->load->helper('form');
$this->load->view('test_form');
}
function get_vales()
{
if ( $this->input->post('button1') )
{
echo "button one clicked<br>";
}
else
{
echo "button one not clicked<br>";
}
if ( $this->input->post('button2') )
{
echo "button two clicked<br>";
}
else
{
echo "button two not clicked<br>";
}
}view file
Code:
<?=form_open("get_values")?>
<input type='submit' name='button1' value='Click' />
<br>
<button name="button2" value="some_value">Click</button>
</form>Two Submit Buttons in Forms - El Forum - 11-10-2008

Thanks, Barzo. That worked.

Note that you could just name the buttons the same thing with different values:
Code:
//HTML
<input type="submit" value="Save" name="submit_action" />
<input type="submit" value="Save and Finish" name="submit_action" />Code:
//PHP
$action = $this->input->post('submit_action');
if($action == 'Save') {
...
} else if($action == 'Save and Finish') {
...

}This is actually the best method.
