simple php queston

[Mark Winter]

I have a multi select pick list in an html

<FORM ACTION="/progs/read.php" METHOD="POST" target="_blank">^M

<label for="CATEGORIES">Select one or more categories</label>^M
<SELECT MULTIPLE name="CATEGORIES" size="10" id="CATEGORIES"
class="select">
<option value="41">Auto Manufacturers</option>
<option value="27">Biodiesel</option>
<option value="38">Component Suppliers</option>
<option value="39">Conversion Companies</option>
<option value="40">Dealers</option>
<option value="28">Electricity</option>
</select>

in read.php i try to read the value by:

$categories=htmlspecialchars($_POST['CATEGORIES']);
then try to print out the value and all I get is the last value.
I tried to put in an array like:

$categories=array($_POST['CATEGORIES']);

and still got the same result.

What am I doing wrong?

Thank you

You need to turn that into an array. Keep in mind that a <select multiple>
returns several GET or POST variables with the same name. So, you'll have
to use the magic of the [] operator here:

<select multiple='multiple' name='categories[]' ... >

And then, something like:

foreach($_POST['categories'] as $cat)
{
echo $cat;
}

if you just want to get the entries as a string to store in the database
and don't want to display them straight away, you could do the following
and not have to recurse through the array:

$categories = (string)@implode(",", $_POST['categories']));

That would be against normalization techniques, and this type of setup
will cause problems later.
