Correct handling _POST[] and implode. PHP5

Hi all,

I have a form that has has an array of information. Mulitple checkboxes can
be selected.

Choose the colors:

Green
Yellow
Red
Gray

When processing the form..

echo $_POST['Colors'] . '
'; // outputs 'Array'

if ( isset($_POST['Colors']) ) {
$_POST['Colors'] = implode(', ', $_POST['Colors']); //Converts an array
into a single string
}

echo "Colors you chose: {$_POST['Colors']}
";

I get the following error when using the implode function.

Warning: implode() [function.implode]: Bad arguments

What I doing wrong ?

Thanks in advance.

Its Simple...

Its very obvious that $_POST["color"] is not an array.

do something like this and you wil get the values.

$arr_color = $_POST["colors"];

//iterate over the array
foreach($arr_color as $val)
{
$str_color .= ", " . $val;
}

You are done.

so it's simple=2C it's not an array=2C but your assignment magically makes =
it an array since you wrote "iterate over the array" ... very=2C very clear=
=2C isn't it?

echo implode('=2C'=2C $_POST['Colors'])
=3B

RE: Correct handling _POST[] and implode. PHP5

Hi Andrea,

Thanks for your responses.

The output from echo '

', var_dump($_POST['Colors']), '

', var_dump($_POST['Colors']), '

RE: Correct handling _POST[] and implode. PHP5

I just realised I have get_magic_quotes_gpc turned on and was not catering
for arrays.

Thanks for your time.

that's why I asked about PHP version ... latest have magic_quotes and regis=
ter_globals off by default and I strongly suggest to configure whatever ser=
ver like that because there shouldn't be anything "magic" when we talk abo=
ut security or programming.
