Multiple Checkbox Values into String

[christophorus]

I am trying to collect the values from multiple checkboxes into a string. If the user selects lets say 3 of the choices, how do i format them into a string like "AK,CA,CO,". Do I need to create an array first?


<form name="states" method="POST" action="<? $_SERVER['PHP_SELF']; ?>">

<input type="checkbox" name="state1" value="Nationwide">
Nationwide</p>
<input type="checkbox" name="state2" value="AK,">
AK
<input type="checkbox" name="state3" value="AL,">
AL
<input type="checkbox" name="state4" value="AR,">
AR
<input type="checkbox" name="state5" value="AZ,">
AZ
<input type="checkbox" name="state6" value="CA,">
CA
<input type="checkbox" name="state7" value="CO,">
CO
<input type="checkbox" name="state8" value="CT,">
CT
<input type="submit" name="Submit" value="Get Data">
</form>

call each checkbox "checkbox[]"

each selected checkbox will, on submission, be in the array $_POST['checkbox']

to get into a string use implode()

Seeing as you will get an array, you might consider keeping the data that way.

$_POST['messages']['noneselected'] = "<p><strong>None selected</strong></p>";

if (count($_POST['checkbox']) > 0)) {
echo "<ul>";
  for ($i = 0; $i < count($_POST['checkbox']); $i++) {
    echo "<li>{$_POST['checkbox'][$i]";
  }
echo "</ul>";
}
else {
echo $_POST['messages']['noneselected'];
}

ps. take this as psuedocode
