Reteriving variable values

bschwartz

I am using a count variable at the end of my other variables, and I am having trouble getting the values of these variables bacl

See attached image of project.

Each column has its own variable name + each row has a $cnt variable.
Like workorder1, cwa1, prime1, workorder2, cwa2, prime2, etc ....

How can I call these variables to post in the table if a user has already submitted values?

I'm trying this a couple of different ways, but I can't get either way to work. Can someone let me know which is best, and what will work.

print "<td><input name=\"release$cnt\" type=\"text\" size=3 maxlength=7 VALUE=\"$release$cnt\"></td>\r\n";

  if ($provider[$cnt] =="") {
	print "<select name=\"provider$cnt\">\r\n";
    print "<option value=''>Select a provider</option>\r\n";
    print "<option value='2'>AT&T/SBC</option>\r\n";
    print "<option value='1'>Metro PCS/T-Mobile</option>\r\n";
    print "<option value='3'>Sprint/Verizon/Nextel</option>\r\n";
	print "</select>\r\n";
	} else {
	print "value=\"$provider$cnt\"";
	}

Try this:

if ($provider[$cnt] =="") {
    print "<select name='".$provider$cnt>"'>\r\n";
    print "<option value=''>Select a provider</option>\r\n";
    print "<option value='2'>AT&T/SBC</option>\r\n";
    print "<option value='1'>Metro PCS/T-Mobile</option>\r\n";
    print "<option value='3'>Sprint/Verizon/Nextel</option>\r\n";
    print "</select>\r\n";
    } else {
    print "value='".$provider$cnt."'";
    }

Well, even at a more basic level than that. $provider and $cnt are both variables and I cannot get the values to return when they are next to each other like that. Any suggestions there?

I think what you are after is:

print 'value="'.${"provider$cnt"}.'"';

However, I'd strongly recommend using an array approach, e.g. naming your form fields as array elements:

<input type="text" name="provider[]">

Then you could just use:

print 'value="'.$provider[$cnt].'"';

Plus it allows you to use array functions on the $provider array as well as the foreach() construct.

If they are named as array elements will that distinguish between the different items? The way I am looking at it, which could be all wrong, I will have 10+ variables called "provider[]", and I won't have a way to tell them apart.

PHP will turn them into an array called $POST['provider'] (or $GET['provider'] if your form uses the "get" method. So the first one will be $POST['provider'][0], the second $POST['provider'][1], etc....

You can assign it to a simpler varialbe to save some typing:

$provider = $_POST['provider'];
echo "The first provider value is: " . $provider[0];

Since it's an array, you can do PHP array things with it, like:

foreach($provider as $key => $value)
{
   echo "Provider #".$key." has a value of: ".$value."<br />\n";
}
