One line if statement in PHP

Question

I'd like to to some thing similar to JavaScript's

var foo = true;
foo && doSometing();

but this doesn't seem to work in PHP.

I'm trying to add a class to a label if a condition is met and I'd prefer to keep the embedded PHP down to a minimum for the sake of readability.

So far I've got:

<?php $redText='redtext ';?>
<label class="<?php if ($requestVars->_name=='')echo $redText;?>labellong">_name*</label>
<input name="_name" value="<?php echo $requestVars->_name; ?>"/>

but even then the IDE is complaining that I have an if statement without braces.

Answer 1

use the ternary operator ?:

change this

<?php if ($requestVars->_name == '') echo $redText; ?>

with

<?php echo ($requestVars->_name == '') ? $redText : ''; ?>

In short

// (Condition)?(thing's to do if condition true):(thing's to do if condition false);
