Certain variables from HTML form not getting echoed

Question

I'm building a simple tool that will assemble a string based on HTML form input.

However, two variables are not being pulled into the string as expected.

Here is the HTML form:

<form action="stringmaker.php" method="post">
<label for="subline">Subject line:</label>
<input type="text" id="subline" name="subline" size="30" /><br /><br />

<label for="emailtype">Email Type</label>
<select name="emailtype">
<option value="advocacy" selected>Advocacy</option>
<option value="fundraising">Fundraising</option>
<option value="newsletter">Newsletter</option>
<option value="event">Event</option>
<option value="cultivation">Cultivation</option>
</select><br /><br />

<label for="campaign">Campaign</label>
<select name="campaign">
<option value="campaign1" selected>Campaign 1</option>
<option value="campaign2" selected>Campaign 2</option>
<option value="campaign3" selected>Campaign 3</option>
<option value="campaign4" selected>Campaign 3</option>
</select>

<h3>Audience Information</h3>
<label for="audiencetype">Audience Type</label>
<select name="audiencetype">
<option value="noaudiencetype" selected>None</option>
<option value="interestgroup">Interest Group</option>
<option value="donors">Donors</option>
<option value="actiontakers">Action-Takers</option>
</select><br /><br />

<label for="geo">Audience Geography</label>
<select name="geo">
<option value="national" selected>National</option>
<option value="state">State</option>
<option value="district">District</option>
<option value="city">City</option>
</select><br /><br />

<label for="statename">State</label>
<select name="statename">
<option value="ak" selected>Alaska</option>
<option value="al">Alabama</option>
<option value="az">Arizona</option>
<option value="dc">Washington, D.C.</option>
</select><br /><br />

<input type="submit" value="Go" name="submit" />

And here is the PHP:

<?php
$subline = $_POST['subline'];
$emailtype = $_POST['emailtype'];
$campaign = $_POST['campaign'];
$audiencetype = $_POST['audiencetype'];
$geo = $_POST['geo'];
$statename = $_POST['statename'];

echo "<p>Here's your string!<br>";
echo $subline,"|",$emailtype,"|",$campaign,"|",$audiencetype,"|",$geo,"|",$statename;
?>

The output is missing the first ($subline) and fifth ($geo) variables, and I can't figure out what is different with those.

Thanks for your help.

Try echo $subline."|".$emailtype."|".$campaign."|".$audiencetype."|".$geo."|".$statename; dots are to concatenate, not commas. Plus, your question's code is missing a closing </form> tag. — Funk Forty Niner

Sorry, @Fred-ii- is incorrect. echo allows multiple arguments, and it prints them all. — Barmar

Edit:

As it stands, both dots and commas are acceptable, my mistake.
Your form is/was missing </form> tag, least from your originally posted code.

Everything echoe'd correctly in my test.

The only thing I can come up with to explain why $subline is empty, is that it hasn't been filled. Everything else checks out.

I also noticed that you also have all of these as selected

<option value="campaign1" selected>Campaign 1</option>
<option value="campaign2" selected>Campaign 2</option>
<option value="campaign3" selected>Campaign 3</option>
<option value="campaign4" selected>Campaign 3</option>

Sidenote: You have 2x Campaign 3, but that wouldn't affect anything.

There should only be one.

<option value="campaign1" selected>Campaign 1</option>
<option value="campaign2">Campaign 2</option>
<option value="campaign3">Campaign 3</option>
<option value="campaign4">Campaign 3</option>

(Fixed it to be Campaign 4)

<option value="campaign1" selected>Campaign 1</option>
<option value="campaign2">Campaign 2</option>
<option value="campaign3">Campaign 3</option>
<option value="campaign4">Campaign 4</option>

One of my test results:

Here's your string!
test|fundraising|campaign3|noaudiencetype|district|ak

~~original answer:~~

~~Plus, your question's code was missing a closing </form> tag.~~

Read the documentation. The syntax is echo $arg1, $arg2, $arg3, ...

@Barmar Yes, my mistake. I tested with both commas and dots and it worked. I think it's only the missing </form> tag.

Why would that omit only subline and geo?

@Barmar That's what I'm trying to find out. If I can't find the actual problem, I will delete my answer.
