How to add a "." if a particular field is filled out on a form

[bbw82]

I have a form where people will be putting in specific info such as their names and other info.  When the form is posted I need to add a "." between the fields on the output depending on if it is filled out or not if field is blank do not need a "."

 

Example if they put in their name Bob Marley on the form I need it to appear on the output as Bob.Marley.

 

Here is the code using currently which also excludes blank fields

 

echo $_POST["First"];

 

  if(isset($_POST["Middle"])){

echo $_POST["Middle"];

}

 

echo $_POST["Last"];

Hi.  I'd suggest changing your code to what Mj mentioned.

use isset

 

Um, let's not, since that won't work. A field that a users does not fill in a value for is still set - it just happens to have a value of an empty string. And, you should always use trim() on user input. Otherwise, a value of only spaces will appear as having a non-empty value.

 

$first    = trim($_POST['First']);
$middle   = trim($_POST['Middle']);
$last     = trim($_POST['Last']);
$personal = trim($_POST['Persona1']);

if(!empty($middle)) { $middle = $middle.'.'; }

echo "{$first}.{$middle}{$last}.{$personal}.<br>\n";

 

Although you should really think about using htmlentities() on the values to prevent any values that might be interpreted as HTML code from screwing up the page.

$first = "Bob";
$last = "Marley";

echo $first . "." , (isset($middle))? $middle."." : "" , $last . ".";

 

Will just print "Bob.Marley." when $middle has no value.
