[RESOLVED] How return value from select option dropdowns

[DKY]

I have the form below and it is not passing anything in the 'filter' section and I can't figure out why. i'm using this dropdown to filter out the UC criteria so i would need some sort of usable value that I can then spit into a query to filter out my results. Help?

ECHO "<FORM NAME='filter' METHOD='post' ACTION='".$_SERVER["PHP_SELF"]."?filter=".$_POST["uc"]."' ENCTYPE='multipart/form-data'>";
ECHO "&nbsp;&nbsp;Filter by Unit Code?&nbsp;";
ECHO "<SELECT name='uc' onchange='this.form.submit()'>";
ECHO "<OPTION VALUE='ALL'>ALL</OPTION>";

$DispQueryUC = "SELECT DISTINCT UC FROM $MaxxForceInventoryTable ORDER BY UC ASC";
$DispResultUC = mysql_query($DispQueryUC) or die(mysql_error().'<br />');
	while ($Row = mysql_fetch_assoc($DispResultUC))
	{
		ECHO "<OPTION VALUE='" . $Row["UC"] . "'>" . $Row["UC"] . "</OPTION>";
	}

ECHO "</SELECT>";

First
check out that your form have actually some values in OPTIONS
This is simply to look at the View Source in your browser.
(<OPTION VALUE='" . $Row["UC"] . "'>" . $Row["UC"] . "</OPTION>)

Next is simply to see what is posted to your actionpage.
That is the value: $_POST['uc']

This is not a difficult script to debug and track down.

I have values

<FORM NAME='filter' METHOD='post' ACTION='/MaxxForce/index.php?filter=' ENCTYPE='multipart/form-data'>&nbsp;&nbsp;Filter by Unit Code?&nbsp;<SELECT name='uc' onchange='this.form.submit()'><OPTION VALUE='ALL'>ALL</OPTION><OPTION VALUE='3Q'>3Q</OPTION><OPTION VALUE='3R'>3R</OPTION><OPTION VALUE='5A'>5A</OPTION><OPTION VALUE='5D'>5D</OPTION><OPTION VALUE='5P'>5P</OPTION><OPTION VALUE='A2'>A2</OPTION><OPTION VALUE='B1'>B1</OPTION><OPTION VALUE='C1'>C1</OPTION><OPTION VALUE='C3'>C3</OPTION><OPTION VALUE='D1'>D1</OPTION><OPTION VALUE='D4'>D4</OPTION><OPTION VALUE='D5'>D5</OPTION><OPTION VALUE='D6'>D6</OPTION><OPTION VALUE='M1'>M1</OPTION><OPTION VALUE='M6'>M6</OPTION><OPTION VALUE='N2'>N2</OPTION><OPTION VALUE='N3'>N3</OPTION><OPTION VALUE='N4'>N4</OPTION><OPTION VALUE='P1'>P1</OPTION><OPTION VALUE='P6'>P6</OPTION><OPTION VALUE='Q1'>Q1</OPTION><OPTION VALUE='Q2'>Q2</OPTION><OPTION VALUE='Q4'>Q4</OPTION><OPTION VALUE='R1'>R1</OPTION><OPTION VALUE='S5'>S5</OPTION><OPTION VALUE='T3'>T3</OPTION><OPTION VALUE='U5'>U5</OPTION><OPTION VALUE='X8'>X8</OPTION><OPTION VALUE='Z1'>Z1</OPTION></SELECT></FORM>

How do I do the next step?

One way would be:

print_r($_POST)

and see if there is a value for $_POST['uc']

[DKY]

I put it right before the </SELECT> and I get this

Array ( [uc] => 5P ) 1

When I select 5P

had to use GET in my action on my form instead of POST.
