trim all!

[junglejim]

i have a form passing to a php script (that writes it to a txt file)
the form has many fields!
please show mw a better way to trim than this.....
do i have to do each one at a time?

$date1 = trim("$date1");
$date2 = trim("$date2");
$date3 = trim("$date3");
$date4 = trim("$date4");
$date5 = trim("$date5");
$address1 = trim("$address1");
$address2 = trim("$address2");
$address3 = trim("$address3");
$address4 = trim("$address4");
$address5 = trim("$address5");
$text1 = trim("$text1");
$text2 = trim("$text2");

etc etc

To create the variables with trimmed values (substitute $GET for $POST if your form method is 'get')

foreach ($_POST as $varname => $value ) {
    $_POST[$varname] = trim($value);
}
extract ($_POST);

or

foreach  ( $_POST as $varname => $value ) {
    $$varname = trim($value);
}

You can also change your form to actually pass an array by adding brackets to the name value of the tag. For example:

<form>
<input type="text" name="dates[1]">
<input type="text" name="dates[2]">
<!-- etc, etc -->
</form>

OR, better yet, use

<form>
<select multiple name="dates">
<option>Line 1
<option>Line 2
<option>Line 3
<option>Line 4
</select>
</form>

Then your visitors can select multiple options at once. You can then step thru the results with foreach or use print_r to see everything as you test it.

echo "<pre>";
print_r($_POST["dates"]);
echo "</pre>";

and...

foreach($_POST["dates"] AS $key => $value) {
$_POST["dates"] = trim($key);
}
