two buttons in a form

[runrunforest]

Hi,

I have two buttons, one is for submitting, one is for doing something else.

So far, the one supposed to do something else, do the submit too, that's the problem.

<input type="submit" name="submit" id="submit" value="Make change" />

<input type="submit" name="cancel" id="cancel" value="Cancel" />

If($_POST['submit']) { change the info }
 
If($_POST['cancel'] { go back to previous page }

If you have an answer for me, I'd also appreciate to hear how to handle 3 buttons.

That should work. Post your actual code instead of retyping what you think your code is. It's probably a stupid mistake.

The full code for processing form, this is for changing user's information. After done, user is redirected back to user section. If cancel, user will be also back to user section.

The form validates the input first then processes the change to database.

$errors = array();
$url = URL;
$username = $_COOKIE['active']['username'];
 
if(isset($_POST['submit']))
{
	$fields = array('email','name', 'land_line', 'address', 'city', 'region');
 
	foreach($fields as $field)
	{
		${$field} = mysql_real_escape_string(trim($_POST[$field]));
	}
 
	if(empty($email)) {$errors[] = ' need email';}
 
	if(empty($name)) {$errors[] = 'need name';}
 
	if(empty($land_line)) {$errors[] = 'need land_line number';}
 
	if(empty($address)) {$errors[] = 'need address';}
 
	if(empty($city)) {$errors[] = 'need city';}
 
	if(!empty($email) && !empty($name) && !empty($land_line) && !empty($address) && !empty($city) )
	{
		$query2 = "UPDATE user SET 
					email = '{$email}'
					, name = '{$name}'
					, land_line = {$land_line}
					, address = '{$address}'
					, city = '{$city}'
				WHERE username = '{$username}' ";
	}
	$result2 = mysql_query($query2) or die(mysql_error());
 
	if($result2)
	{
		header('location:'.$url.'account.php');
		exit();
	}
}
if(isset($_POST['cancel'])) 
{
	header('location:'.$url.'account.php');
	exit();
}

I've just edited the code slightly and I have this error

Parse error: syntax error, unexpected T_BOOLEAN_AND, expecting ')' in /home/badede/public_html/php/change_info.script.php on line 26

When I don't have error. The two buttons function the same thing, which is undesirable.

I'm not sure, your code works pretty much verbatim when I tested it.

I also did not find any problem with your posted code.

But regarding the buttons, if you don't need to process anything with another button then simply you can use javascript to redirect the browser to the user section directly.

<input type="submit" name="submit" id="submit" value="Make change" />

<input type="button" name="btnCancel" value="Cancel" onClick="document.location='usersection.php';" />

Otherwise if you still want to be safe and redirect from PHP, then the process you have done is OK:
HTML:

<input type="submit" name="btnSubmit" value="Make change" />
<input type="submit" name="btnSubmit" value="Cancel" />

Note the same name of both the buttons.
PHP:

if($_POST['btnSubmit'] == 'Cancel'){
    header('Location:usersection.php');
    exit();
}
else if($_POST['btnSubmit'] == 'Make change'){
    //do some process here.
}

Thank you guys.

Acutally, itsn't a problem.

Because there are some javascript validation in html form, thats why when I click cancel it prompts me to finish some empty textfields, making me think it is a submitting. How silly!
