forms - processing textarea and checkbox variables

Alright, so I got my form to email most of the variables in php. However, my textarea variables show up blank and my textarea inputs print as "Array"

Here is a snippet from my form:

<label for="ProgramAudience">Intended Audience:</label>
                <span><input type="checkbox" name="ProgramAudience[]" value="AcademicAffairsFaculty" />Academic Affairs/Faculty</span>
                <span><input type="checkbox" name="ProgramAudience[]" value="StudentAffairsDevelopment" />Student Affairs/Development</span>
                <span><input type="checkbox" name="ProgramAudience[]" value="CommunityColl开发者_运维问答ege" />Community College/2-Year Institutions</span>
                <span><input type="checkbox" name="ProgramAudience[]" value="GraduateStudents" />Graduate Students</span>
                <span><input type="checkbox" name="ProgramAudience[]" value="FourYearPublic" />Four-Year Public Institutions</span>
                <span><input type="checkbox" name="ProgramAudience[]" value="FourYearPrivate" />Four-Year Private Institutions</span>



<label for="ExpectedOutcome">Expected Learning Outcomes:</label>
                <label class="small">List 1-2 expected learning outcomes below. (As a result of attending this session, participants will...)</font></label>
                    <font size="1" face="arial, helvetica, sans-serif"> ( You may enter up to 400 characters. )<br>
                <textarea name="message4" id="ExpectedOutcome" class="required" wrap="physical" rows="10" cols="35" onKeyDown="textCounter(this.form.message4,this.form.remLen,400);" onKeyUp="textCounter(this.form.message4,this.form.remLen,400);"></textarea>

Here is the part of the processing file:

$ProgramAudience = $_POST['ProgramAudience']; 
$ExpectedOutcome = $_POST['ExpectedOutcome']; 

...

$Body = "";
$Body .= "ProgramAudience: ";
$Body .= $ProgramAudience;
$Body .= "\n";
$Body .= "ExpectedOutcome ";
$Body .= $ExpectedOutcome;

This is what the emailed result looks like:

Check your name attribute on the text area - that's the one PHP will use.

Checkboxes will only come through if they are checked, so make sure you check something. With a name with brackets, like "ProgramAudience[]", the $_POST['ProgramAudience'] variable will either be null or an array. You'll want to check if it's an array, and if so, loop through the contents to generate your email.

For the checkbox arrays, the processing script needed this:

$ProgramTitle = $_POST['ProgramTitle']; 
foreach($_POST['ProgramType']  as  $value)  {
$check_msg .= "Checked: $value\n";
} 

and this:

$Body .= "ProgramTitle: ";
$Body .= $ProgramTitle;
$Body .= "\n";
$Body .= "ProgramType: ";
$Body .= $check_msg;
