Update database based on radio button value

[brandonboyce]

I am populating a table with information from a database, one of the values is a rating 1, 2, 3, or 4. I made it so that depending on the value in the database the radio button with the corresponding value is selected. But I am having problems figuring out how I can update the database when the radio button is changed to a new value. It doesn't have to be changed on click, it can be changed with a submit button after they have made all of the changes they would like to make.

I am fairly new to PHP so I appoligize in advanced if the code is a bit messy. But below is the code I used to populate the table with all of the appropriate values.

while($row2=mssql_fetch_array($SQLresult)) 
{
	//find the competency level
	$complevel = $row2[CompetencyLevel];
	if($complevel=="1") $a="checked";
	if($complevel=="2") $b="checked";
	if($complevel=="3") $c="checked";
	if($complevel=="4") $d="checked";
	//build the table
	echo "<tr class=\"\"><td>".$row2[CompetencyID]."</td><td>".$row2[CompetencyName]."</td>";
	echo "<td class=\"lft\"><input type=\"radio\" name=\"".$groupnum."\" value=\"1\"".$a."> 1";
	echo "<input type=\"radio\" name=\"".$groupnum."\" value=\"2\"".$b."> 2";
	echo "<input type=\"radio\" name=\"".$groupnum."\" value=\"3\"".$c."> 3";
	echo "<input type=\"radio\" name=\"".$groupnum."\" value=\"4\"".$d."> 4</td></tr>";
	//increment the group number
	$groupnum++;
	//clear the variables
	$a="";
	$b="";
	$c="";
	$d="";
}

Same answer that I gave to someone yesterday. You need to create a proper form and then you need to process the results from the form. Have a look at the two links below and try to apply what they are telling you.

Learn about HTML forms

I guess I can't wrap my head around how I would pass the value to the database when the form is submitted. The query returns a different number of rows for each person it is run on, each of those rows has to be rated then 1 - 4. I guess what I am having problems grasping is how I would pass the value of the radio button, the ID of the person and the id of the field that is being updated with 1 - 4 when submit is pressed.

Thinking about it I could probably use a couple of hidden inputs to hold the ID values I would need to update the database. I'll give it a try and see what I can come up with.

I think I found the answer to my questions here http://www.phpeasystep.com/mysql/10.html hopefully it helps other people looking to solve the same problem

I tried and I seem to be missing something. Here is what I've added to my original above.

while($row2=mssql_fetch_array($SQLresult)) 
{

	//find the competency level
	$complevel = $row2[CompetencyLevel];
	if($complevel=="1") $a="checked";
	if($complevel=="2") $b="checked";
	if($complevel=="3") $c="checked";
	if($complevel=="4") $d="checked";
	//build the table
	echo "<tr class=\"\"><td>".$row2[CompetencyID]."</td><td>".$row2[Category]."</td>";
	echo "<td>".$row2[CompetencyName]."</td>";
	echo "<td class=\"lft\"><input type=\"radio\" name=\"".$row2[CompetencyID]."\" value=\"1\"".$a."> 1";
	echo "<input type=\"radio\" name=\"".$row2[CompetencyID]."\" value=\"2\"".$b."> 2";
	echo "<input type=\"radio\" name=\"".$row2[CompetencyID]."\" value=\"3\"".$c."> 3";
	echo "<input type=\"radio\" name=\"".$row2[CompetencyID]."\" value=\"4\"".$d."> 4";
	echo "<input type=\"hidden\" name=\"".$groupnum."\" value=\"".$row2[CompetencyGUID]."\">";
	echo "</td></tr>";
	$groupnum++;
	//clear the variables
	$a="";
	$b="";
	$c="";
	$d="";
}

Then below that I have this code to update sql

if($_POST['Submit']){
	for($i=0;$i<$count;$i++){
		$sqlUpdate="UPDATE data SET CompetencyLevel = '".$_POST[$row2[CompetencyID]]."' WHERE StudentGUID = '".$guid."' AND CompetencyGUID = '".$_POST[$groupnum]."'";
		mssql_query($sqlUpdate);
	}
}

The page refreshes when you press submit but the database doesn't update. I'm just not sure where to go from here, a little help would be appreciated.
