Help with if statement

Hi,

I currently have this code which checks if the getCustomData() has an integer to process the next function. If empty of "0", it doesn't fetch payment.php

<?php $price = (int) getCustomData(); 
if( $price ) {
?>
  <div style="text-align:center;"> Price : $<?php echo getCustomData();?>
    <?php require( 'payment.php' ) ?>
    </form>
  </div>
<?php } ?>

Code (markup):

However, now payment.php has changed a lot so I need to make it so that if "0" or "free" is passed as getCustomData(), payment.php should not be parsed/processed. If that makes sense?

Many thanks

 

You can try:

 

nope, that still parses the payment.php

 

i duhno if i understood the question rite

by why dont u use the break command

 

I just don't want to parse/process payment.php if the getCustomData() is set to free or '0'

 

<?php
$price = (int) getCustomData();
if( $price != 0 && $price != 'free' ) {
?>
<div style="text-align:center;"> Price : $<?php echo getCustomData();?>
<?php require( 'payment.php' ) ?>
</form>
</div><?php }
else
break;
?>


Try it out

 

Erm..doesn't work either. :-(

 

Try

<?php
$price = getCustomData();
if( $price != 0 && $price != 'free' ) {
?>
<div style="text-align:center;"> Price : $<?php echo getCustomData();?>
<?php require( 'payment.php' ) ?>
</form>
</div><?php }
else
break;
?>

 

Aah, the very first one posted by mulari worked. My bad, I wasn't puting 0 or free inthe right field.

Many thanks, mulari and powerextreme.

 

Just one more request: Is it possible to NOT parse/process payment.php when the getCustomData is EMPTY, but only on 0 or free?

Many thanks

 

if u use this code

<?php
$price = getCustomData();
if( $price != 0 && $price != 'free' ) {
?>
<div style="text-align:center;"> Price : $<?php echo getCustomData();?>
<?php require( 'payment.php' ) ?>
</form>
</div><?php }
else
break;
?>

Code (markup):

It will happen that way only i guess

 

nope, if getCustomData is empty, it doesn't parse payment.php, whereas I want it to parse when its EMPTY, but NOT when 0 or free is defined.

 

<?php
if($price == NULL) {
require( 'payment.php' );
}
?>

you have to add that code to do that

 

    <?php $price = getCustomData();
		if( $price != 0 && $price != 'free' && $price == NULL ) { 
	?>

Code (markup):

right?

doesn't work. :-(

 

Change the statment too

$price != 0 || $price != 'free' || $price == NULL

Code (markup):

 

A little confused. Which conditions do you want it to process payment? and which conditions not?

When it is 0 or free it does NOT process payment?
and when it is empty it does process payment?

Because 0 is considered empty. I mean $price == 0 is the same as $price == NULL. Correct me please.

So I think when you tell the script to not process payment when its null or free, then contradict by wanting it to process when its empty (null)-- Hope I understand you.

 

i assume 0 and null are diffrent - null is empty and 0 is a value . correct me if i am wrong

 

I said this because in the php manual it says:

The following things are considered to be empty:

"" (an empty string)
0 (0 as an integer)
"0" (0 as a string)
NULL
FALSE
array() (an empty array)
var $var; (a variable declared, but without a value in a class)

 

payment.php is now processed/parsed on EMPTY and '0' value, but not only on 'free'. It should also NOT be processed on '0'.

 

Tried this and it works now as desired.

if( $price_cost != 0 || $price_cost != 'free' && $price_cost == NULL )

Thanks all for help.
