A select optiion + php problem

yuda_zdk

Hi all

I have in the html select optin like this:

<SELECT NAME="open_season_date" value="<?= $open_season_date?>">
<option value=1>Jan
<option value=2>Feb
<option value=3>Mar
<option value=4>Apr
</SELECT>
whereas $open_season_date is a php variable. It's value is
$open_season_date=3.
The problem it keeps showing me Jan (as if it's value is 1).
What should I do to make it show Mar (like it's true value 3) ?

Thanks and regards

You need to tell it to select the option that's value is equal to that of $open_season_date ($date in my example)

i.e.

$date = 2; // or whatever
echo "<select name=\"date\">";
echo "<option value=\"1\""; if($date == 1) echo "selected"; echo ">Jan</option>";
echo "<option value=\"2\""; if($date == 2) echo "selected"; echo ">Feb</option>";
echo "</select>";

I assume your a newbie, so I will share a tip with you.

Don't leave double or single quotes out of your code. Forgetting them causes errors, corrupt data, or invalid data.

i.e.

<option value=1> should be <option value="1">

Yep. And using single quotes for the php echo means that you can use the html double quotes without the horrible looking \"


$date = 2; // or whatever
echo '<select name="date">';
echo '<option value="1"'; if($date == 1) echo 'selected'; echo '>Jan</option>';
echo '<option value="2"'; if($date == 2) echo 'selected'; echo '>Feb</option>';
echo '</select>';

Much more legible and less prone to typos (missing \ or wrong number of quotes etc)

That's interesting, Roger. I didnt even think about doing it that way. I always thought that echo HAD to have double quotes.

Good to know, thanks for posting.

Nope, either will do, just don't mix them. The only time I use double quotes is in query strings becaus SQL already uses the single quote.


$sql = "SELECT * FROM users WHERE name='$user'":

There is a great debate around here about which style to use, single or double. Me I'm just pragmatic: XHTML uses the double quotes so I use the single for html strings, SQL uses the single so I use the double for sql strings
