[SOLVED] Code Example Request : Validate Words Are Comma Seperated

[MyTheory]

Hi if someone could post an example php code for the following I'd be grateful.

 

So the scenario is that, I invite a user to enter a string of words into a form input box, such as "MyTheory, pocobueno1388, darkfreaks, bad_gui, JustGotAQuestion, cainmi, KEFE, didgydont, steviez, Helminthophobe, studgate, rofl90, EchoFool, ifm1989", I'd like to see an example of validating the  comma seperation.. if someone could post one they have i'd appreciate it.

 

Thanks guys!

Are you asking how to validate the data inside of each comma? You'd just explode the string into an array and validate each item.

[MyTheory]

Nope, not the data inside.. I need make sure the user inputted a comma seperated list..

Is there any minimum requirements?

 

Or say will "a,b" do?

[MyTheory]

Erm it'd be nice if it validated the comma and the space afterwords, that's all I need please.

Will only validate a comma-space delimited list containing the following characters:

 

a-z and A-Z

0-9

_ (underscore)

- (dash)

 

<?php
$data = 'MyTheory, pocobueno1388, darkfreaks, bad_gui, JustGotAQuestion, cainmi, KEFE, didgydont, steviez, Helminthophobe, studgate, rofl90, EchoFool, ifm1989';
$result = eregi('^([a-z0-9_\-]+, )+[a-z0-9_\-]+$', $data) ? 'valid' : 'invalid';
echo $result;
?>

Or else this is slightly more cumbersome, but will validate any characters, provided each part is separated by a comma and a space:

<?php
function is_it_good($entered_data) { //////////

$test = explode(',',$entered_data);

if (count($test) > 1) {
    $goodcount = 1;
    foreach ($test as $i => $data) {
            if ($data[0] == ' ') {
                $goodcount++;
            }
    }
    if ($goodcount >= count($test)) {
        $result = 1;
    } else {
        $result = 0;
    }
} else {
    $result = 0;
}
if ($result == 1) {
    echo 'Thats OK!';
} else {
    echo 'Thats not working fool!';
}
} /////////////////////////////////////////////

$entered_data_1 = "abcdef";
$entered_data_2 = "abobo booyah chilli";
$entered_data_3 = "MyTheory, pocobueno1388, darkfreaks, bad_gui, JustGotAQuestion, cainmi, KEFE, didgydont, steviez, Helminthophobe, studgate, rofl90, EchoFool, ifm1989";

echo $entered_data_1.'<br />';
is_it_good($entered_data_1);
echo '<br /> <br />';

echo $entered_data_2.'<br />';
is_it_good($entered_data_2);
echo '<br /> <br />';

echo $entered_data_3.'<br />';
is_it_good($entered_data_3);

?>
