empty field->dont show in email

Hello, how may this be realised in email-Template custom?

now:
[code<table>
<tr><td>field1</td><td>{field1}</td></tr>
<tr><td>field2</td><td>{field2}</td></tr>[/code]

to something like

<?php echo "<table>"
if (!empty({field1})) { echo <tr><td>field1</td><td>{field1}</td></tr>} 
if (!empty({field2})) {echo<tr><td>field2</td><td>{field2}</td></tr>

?>

oh sorry for asking,
I found some similar threads now in the forum

Hello, Its getting tougher now
i need a statement like if !empty and !some_value of dropdown show in email

<?php if(!empty($form->data["myfield"]) || !($form->data["myfield"] == some_value)): ?>
myfieldlabel: {myfield}<?php endif; ?>

Hi mdma,

That should work OK. what exactly is the problem?

Bob

PS I prefer to use a Custom code action before the Email action to process the data and build parts of the template code but either method should work OK.

Hello Bob!!
first part is working with !empty field
second part !value of the field doesnt work...
<?php if(!empty($form->data["myfield"]) || !($form->data["myfield"] == some_value)): ?>
myfieldlabel: {myfield}<?php endif; ?>

maybe something ith isset?

and :

<?php if(!empty($form->data["other_txt_field"])): ?>
other_txt_fieldlabel: {other_txt_field}<?php endif; ?>
