[RESOLVED] Help with IF

jbachris

If I want to do an IF statement to see if there is any content in a text field how could I do that?

<? if ( $news_rs->Fields("story") == ??? { ?>
DISPLAY TEXT

Basically, IF there is any content in the $story field display the text, if there isn't, then nothing.

You should just be able to echo $story. If there's no text in it then nothing will be shown.

What is $news_rs->Fields("story"), and where does it come from?

Anyway, for an incoming variable like $_POST['story'], check with [man]isset/man or [man]empty/man, followed by say [man]strlen/man. If you are willing to consider '0' as an empty value, then using empty() is enough.

I'm sorry, I know that. But I have a label like:

<tr>
<td>EMAIL:</td>
<td><? echo $email; ?></td>
</tr>

What I am trying to do is if there is no $www, not even to display that table row.

My sql query is:

$the_person_rs = $conn->Execute ( "SELECT * FROM aif_memberinfo, phpbb_users WHERE user_id=member_userid AND member_userid=" . $_GET['member_userid'] . "" ) or die ( $conn->ErrorMsg() );

Where does $www come from? Is it guaranteed to exist (i.e. it isnt an incoming variable)? If so, just use strlen(), e.g.

<?php
if (strlen($www) > 0) {
	echo '<tr>
<td>WWW:</td>
<td>' . $www . '</td>
</tr>';
}
?>

My sql query is:

How does your SQL query matter here?

that is where $www is coming from.

that is where $www is coming from.

Well, then $www is guaranteed to exist, so just use strlen().
