Good afternoon everyone!

Plain and simple... here's what I need help with:

[fire_chief_name] and [fire_chief_email] need to be required form fields if either [mem-type='alternate'] or [mem_type='delegate'] are selected from the list/menu. If not, neither [fire_chief_name] or [fire_chief_email] need to be required.

Here is a link to the actual form:
... and here is the code:

for a proof of concept see the below:

Code: 
<?php
$field1 = isset($_POST['field1']) ? trim ($_POST['field1']) : "";
$memtype = isset($_POST['memtype']) ? trim($_POST['memtype']) : "";	
$error = NULL;

if (isset($_POST['submit'])){
	switch ($memtype){
		case "one":
			//field1 required
			if (empty($field1)) {
				$error[] = "You must complete field 1";
			}
			break;
		case "two":
			//
			break;
		default:
			//
	}
	
	if (!is_null($error)){
		$error= "<div class=\"error\">". implode("<br/>", $error) . "</div>";
		displayForm($error);
	} else {
		echo "form properly submitted";
		//do something with it
	}
} else {
	displayForm();
}

function displayForm($error=Null){
global $field1;
?>
<style> .error{color:red;}</style>
<form method="post" action="<?=$_SERVER['PHP_SELF']?>">
<fieldset>
	<?=$error?>
	Type:	<select name="memtype">
				<option value="one">One</option>
				<option value="two">Two</option>
			</select><br/>
	Potentially Required Field: <input type="text" name="field1" value="<?=$field1?>" /><br/>
	<input type="submit" name="submit" value="submit" />
</fieldset>
</form>
<?php
}?>

You need to check fist whether mem_type is one of the 2 options. and then check whether the two fields you need are filled.

example:
Code: 
if(($_POST['mem_type']=='alternate')||($_POST['mem_type']=='delegate')){
if(($_POST['fire_chief_name']!='')&&$_POST['fire_chief_email']!='')){
\\[green]continue with processing of form[/green]
}
else{[green]\\Either one of those is not filled in. [/green]}
}

else{
\\[green]Since the mem_type is neither of those options, the 2 fields in question require no validation for emptiness move one with the rest of the form validation.. [/green]
}

Ignorance is not necessarily Bliss, case in point:
Unknown has caused an Unknown Error on Unknown and must be shutdown to prevent damage to Unknown.
