Checking if two variables are not empty in PHP

I want to echo variables if either of them aren't empty.

I have written the following PHP but they aren't being shown when the variables aren't empty:

if(!empty($this->element->videos||$this->element->productdownloads)) {
    echo $this->element->videos; 
    echo $this->element->productdownloads; 
}

Try

if(!($this->element->videos && $this->element->productdownloads)){
    echo $this->element->videos; 
    echo $this->element->productdownloads;  
}

Well, I have had quite number of issues like that.

Try to remove empty space from the two variables before comparing them. Sometimes empty spaces comes before the variable and that hinders comparison.

if(!$this->element->videos || !$this->element->productdownloads) 
{
    echo $this->element->videos; 
    echo $this->element->productdownloads; 
}

You dont need to use empty by default php checks for empty when you use ! sign with if condition

When checking with the OR operator (||) the code will execute if one or none of them is empty. But you echo both variables even if one of them is empty.

What I think you want to do is use the AND operator(&&). This way, the code will only execute if none of the variables are empty.

<?php   if(!empty($this->element->videos) && !empty($this->element->productdownloads)) {
    echo $this->element->videos; 
    echo $this->element->productdownloads; }
?>

if you still want to show videos, even if productdownloads is empty (and vice versa), you could do a seperate if for each of them, like this:

if(!empty($this->element->videos){
    echo $this->element->videos; 
}
if(!empty($this->element->productdownloads){
    echo $this->element->productdownloads; 
}

edit: minor grammatical fixes
