Shortening PHP instead of repeating serveral code?

                    if (empty($_POST['title'])) {
                    echo "empty";
                    }

PHP:

With my above code, I want to check if $_POST['title'], $_POST['link_description'] and a few others are empty or not, instead of repeating the above code can I use like a comma or something somewhere so I can just do $_post['title'], $_post['link_description']

..etc

Thanks

 

You can use for example such a short construction:

if (!@$_POST['title'] || !@$_POST['link_description'] || !@$_POST['field3'])
 echo "Wrong input";

PHP:

 

Sure, just use a loop.

$requiredFields = array('title','link_description','and_so_on');
foreach ( $requiredFields as $field ) {
    if ( empty($_POST[$field]) ) {
        echo $field. ' is empty';
    }
}

PHP:

 

That's easier for a few fields, but for a lot of fields use the loop.. little explanation for in the future

if (somthing == something_else || blablsfsdf == adas && as==asd) {
}

PHP:

|| means OR
&& means AND

 

foreach ($_POST as $key => $value)
if($value == NULL){ $error .= 'Please enter a value for the '.$key.' field';}
}
if($error == NULL){
//do your post stuff here
}

PHP:

Peace,
