Array Values from Form

[PCHomepage]

In trying to select multiple values from a form drop down (select) list, I am not sure how to use the results.

For example, the code below gives me a comma-separated list but it also puts a comma at the end that causes issues.

if(!empty($_POST['Clinic'])) {
	if (is_array($_POST['Clinic'])) {
		foreach($_POST['Clinic'] as $key => $val) {
			echo $val. ",";
		}
	}
}

However, I need the results to be as a string variable but when I try the following, it gives only the last value. I am quite rusty in PHP so can anyone help get me going?

if(!empty($_POST['Clinic'])) {
	if (is_array($_POST['Clinic'])) {
		foreach($_POST['Clinic'] as $key => $val) {
			$GetClinic = $val;
		}
	}
}

Thanks!

Your loops do 2 completely different things. One outputs to screen as it runs the foreach loop, the second one simply overwrites the variable each time it runs. so at the end you get the last value.

The easy way, use the implode function.

No need for a loop, it does it in a single line.

$mystring=implode(",",$_POST['Clinic']);

http://php.net/manual/en/function.implode.php

The slightly harder way, concatenate each item with a comma and then remove the last comma from the string:

foreach(...){
$myvar[COLOR=red yellow].[/color]=$val . ",";
}

And then remove  the last comma:
$myvar=substr($myvar,0,strlen(myvar)-1);

Great, thanks! I knew what was happening but I wasn't sure what to do about it. The latter is what I was trying to remember (I knew had to do with a dot) but the former is what I used because it's clearly simpler.

I appreciate the help.
