How do I verify that certain variables match

[ricerocket]

I'm having trouble doing this and I can't find anything about in online anywhere so I though I would just ask

 

I need to make something that verifies that two post variables match eachother otherwise output an error message such as below:

 

$password = $_POST['password']
$password_confirmation = $_POST['passconfirm']

if ( $password = $password_confirmation ) {
} else { 
$ermsg = "Passwords do not match please go back and try again";
}

 

but I'm not sure how exactly to create this since I'm not very good at php...

[cooldude832]

look at the operators on php.net

 

http://us3.php.net/manual/en/language.operators.php

 

== is probably what you want

[ricerocket]

ok so the code I created will work it just needs to use == ? Thats what I was stuck on and I couldn't figure out why I couldn't get it to do what I wanted.

[cooldude832]

= will define

$var =  "This value";

== is a comparisons (read on operators for specifically on its compare mode) and returns TRUE or FALSE on success.

 

[ricerocket]

ok so if that is what I need would I use

 

$a == $b for equal variables

 

or

 

$a === $b for identical variables?

 

because the passwords must match for it to not give an error

[cooldude832]

=== is a bit more than == and really shouldn't be used unless you find a reason

examples

 

<?php
$var1 = "1";
$var2 = 1;
if($var1 == $var2){
#True
}
if($var1 === $var2){
#false
}
if($var1 == "1"){
#true
}
if($var1 === "1"){
#true
}
if($var1 === 1){
#should be false
}
?>

 

Get it better?

[ricerocket]

Ok I get it now so I should do something like this:

 

$password = $_POST['password'];
$password_confirmation = $_POST['passconfirm'];

if ( $password != $password_confirmation ) {
$ermsg = "Passwords do not match please go back and try again";
}

 

That way if they're anything but matching it will output the error message. This would work right?
