Errant Spaces and "If" statments

I've been using if statements to test for optional information.

If the information is present then it's displayed on the web page along with a heading.

The problem is that if inadvertently there's a space or a return in an optional field, it's interpreted as content and the heading appears on the page.

Anyone know how I would test for spaces and returns with no other characters present and not show the headings?

Thanks

Hi Jerry,

The's a few ways to do this. I just did a quick search and there's a built in PHP function called ctype_space that checks for whitespace. Note this won't work if the content has PHP tags in it, but will for whitespace.
http://www.php.net/ctype_space

So you could have something like:

<?php if ($record['title'] && !ctype_space($record['title'])): ?>
<?php echo $record['title'] ?>
<?php endif ?>


Which means "if title has a value AND it's NOT (!) all spacing characters, then show it".

Another way to approach the problem would be to strip leading and trailing spaces after loading the data but before testing if it has a value.

Hope that helps!

I think this will do the trick.

Thanks as always.

I'll post my result here.

Good morning Dave,

Sorry that it took so long to respond.

The fix above works perfectly.

Just curious, You mentioned the option of automatically removing any left over leading and/or trailing spaces, before testing, how would I do that.

Thanks,

Hi Jerry

The remove leading and trailing space option would involve the trim() function. I am thinking if the solution Dave gave you already works though, that should be fine. Either option would have the same result and you've already set that one up.

You can read about the trim function the PHP site here:
