[SOLVED] Loop help please

[realjumper]

Hi,

 

On my form I have a list like this.....

 

<select name="related_sections" multiple>
<option selected="selected">Related Section Heads</option>
<option value="[email protected]">Academic Registry</option>
<option value="[email protected]">Dining Hall</option>
<option value="[email protected]">FIS (diploma)</option>
</select>

 

Obviously the user can select more than one option, which is fine. When this form is POSTED to the action.php page, how can I echo the selected options? For example, suppose the user selects all three options: I need to email all three departments, so I would like to have "[email protected],kitchen@hotmail,[email protected]" available to use on my action page.

 

I have had a play around with loops, but I can't seem to get a comma delimited output of the variable $related_sections on my 'action.php' page.

 

Any help would be great, thanks.

Your have to use javascript unless you use radio button's

Oh okay then. Thanks redarrow.....I was hoping to avoid using radio buttons, but that option is still better than javascript I think. Thank you :-)

what about this?

 

<form action="<?php echo $_SERVER['REQUEST_URI']; ?>" method="POST">
<select name="related_sections[]" multiple>
<option selected="selected">Related Section Heads</option>
<option value="[email protected]">Academic Registry</option>
<option value="[email protected]">Dining Hall</option>
<option value="[email protected]">FIS (diploma)</option>
</select>
<br><input type="submit" name="go" value="Submit!">
</form>
<?php
if(isset($_POST['go'])){

$selected = $_POST['related_sections'];
foreach($selected as $s){
echo "Selected: {$s}<br>";
}

}
?>

 

if you wanted to seperate them by comas then simply do this:

 

$selected = implode(",", $_POST['related_sections']);

 

good luck!

Thanks ProjectFear, Your method meant that if I selected 2 options, the loop would run twice....meaning each email address would appear twice. It looks like this:

 

[email protected],[email protected]@hotmail.com,[email protected]

 

If I selected 3 options, then the loop would run 3 times, with predictable results.

 

But what abouth this?.....it seems to work just fine!!

 

<form action="<?php echo $_SERVER['REQUEST_URI']; ?>" method="POST">
<select name="related_sections[]" multiple>
<option selected="selected">Related Section Heads</option>
<option value="[email protected]">Academic Registry</option>
<option value="[email protected]">Dining Hall</option>
<option value="[email protected]">FIS (diploma)</option>
</select>
<br><input type="submit" name="go" value="Submit!">
</form>

<?php
if(isset($_POST['go'])){

$selected = $_POST['related_sections'];
foreach($selected as $s){
$selected = implode(",", $_POST['related_sections']);

}

}

$foo = array($selected);

foreach ($foo as $whatever) {
  ; 
}

echo "$foo[0]";

?>

 

The result of selecting 2 options is:

 

[email protected],[email protected]

 

The result of selecting 3 options is:

 

[email protected],[email protected],[email protected]

 

It works fine....does anyone see anything wrong with doing this??

 

Thanks :-)

running this:

$selected = implode(",", $_POST['related_sections']);

 

when i copy your code produces what you have above.

 

[email protected],[email protected],[email protected]

 

no need to run a loop if you want the commas.
