[SOLVED] "Else Do Nothing" not working

[Moron]

<?php

if(!empty($RESULT['PSTU62']))  {

echo $RESULT['PSTU62']; 
echo "<BR>";

}

else {
}
?>

 

If there is data in the field it echoes it and inserts a break (HTML <BR> tag).

 

But..... if there's nothing in a field, it still inserts a break tag anyway, resulting in too many spaces between entries.

 

Ideas?

You dont need an else statement on that loop.

 

All you want to do is echo out what youve done so you just need

 

<?php

if(!empty($RESULT['PSTU62']))  {
echo $RESULT['PSTU62']."<br />"; 
}
?>

Just adding on, I would check to see if it exists first.

 

<?php

if(isset($_RESULT['PSTU62']) && !empty($RESULT['PSTU62']))  {
echo $RESULT['PSTU62']."<br />"; 
}
?>

 

That way it does not display the index undefined error when that value isn't there.

Thanks, but I'm getting the same result, a "<BR>" inserted even when the field is empty.

 

Using your example, my code now reads:

 

<?php

if(!empty($RESULT['PSTU62']))  {

echo $RESULT['PSTU62']."<br />"; 
}

?>

A side note even a whitespace is considered not empty.

 

<?php

if(isset($_RESULT['PSTU62']) && !empty(trim($RESULT['PSTU62'])))  {
echo $RESULT['PSTU62']."<br />"; 
}
?>

 

The trim function will remove any whitespaces.

 

Here is another variation, that may be better suited that way you the variable exist if not it is null you then use the is_null function to check. And it is trimmed in the definition.

 

<?php
$pst = isset($_RESULT['PSTU62'])?trim($_RESULT['PSTU62']):null; 
if(!is_null($pst) && $pst != "")  {
echo $RESULT['PSTU62']."<br />"; 
}
?>

If you are getting 2 blank lines when it's true and 1 blank line when it's false, you have a blank line being output somewhere else.  Maybe an extra line after your closing php tag ?> or something.  Somewhere other than the else.

Your second example seems to be working for me. Adapting it to my code I'm using:

 

<?php

$message62 = isset($RESULT['PSTU62'])?trim($RESULT['PSTU62']):null; 
if(!is_null($message62) && $message62 != "") {
echo $RESULT['PSTU62']."<br />"; 
}

$message63 = isset($RESULT['PSTU63'])?trim($RESULT['PSTU63']):null; 
if(!is_null(message63) && message63 != "") {
echo $RESULT['PSTU63']."<br />"; 
}

$message64 = isset($RESULT['PSTU64'])?trim($RESULT['PSTU64']):null; 
if(!is_null(message64) && $message64 != "") {
echo $RESULT['PSTU64']."<br />"; 
}
?>

 

...etc.....

 

Thanks!
