Can you see the coding flaw - I can't

[jm33990]

I've stared at this way to long an would be happy (and probably embarrassed) if you can show me the flaw.

Maybe there is no error and I'm doing something illegal....??

 

I'm using a radio button to group two items together. These items show perfectly on the web page but are not returned properly to the posting program.

The first item is shown on the web page and posted back to the same program for processing.

The second item is shown on the web page but NOT posted back to the same program for processing.

They both share the same radio button name.

 

  foreach ($result as $line) {

      list($d1,,,$type,$d2) = split('  +',$line);

      if ($type == "CNAME") {

        list($alias,$discard) = split('[.]',$d1);

        echo "<br>";

        echo "<input type=radio name=\"del\" value=\"#$alias\">$alias";

        }

      echo "</table>";

      }

  echo "<br><br>Comments..<br>";

  foreach ($result as $line) {

      list($d1,,,$type,$d3) = split('  +',$line);

      if ($type == "TXT") {

        echo "<input type=radio name=\"del\" value=\"$d3\">$d3";

        echo "<br>";

        }

      }

After submit the same program pulls the posted info...

  $itemdelete = $_POST['del'];

  echo "startup itemdelete is $itemdelete ...<br>";

If it's $alias passed it's posted OK...if $d3 passed it's empty....why

 

Thank You.

with a radio you can only select one out of the group that has the same name and the one that is selected gets returned.

[jm33990]

I realize that only the selected one is returned

The problem is if the TXT item is selected the $d3 value does not get returned.

If a CNAME item is selected the #$alias value is returned.

I know in both cases it is set properly because I can see them on the web page beside the buttons

thanks anyway for the help

I changed value=\"$d3\" to value=$d3

why that matters yet value=\"#$alias\" is acceptable is a mystery to me...anyone care to explain.

 

summary

value=\"$d3\ --- does not work

value=$d3 --- works

value=\"#$alias\" --- works

value=#$alias ---- works

 

wierd..must be something to do with #

One reason why variable interpolation is confusing. It's hard to tell if you meant the variable $d or $d3. Of course, $d may be undefined, but so what? No one knows what you mean. Try putting braces around the variable if you interpolate them, such as {$d3}. But it's best to just not interpolate them. I suggest string concatenation or string formatting with sprintf or printf.

[jm33990]

you lost me....

 

I thought my original post (and post #3) made it clear we were talking about $d3.

 

I still don't know why \"$d3\" fails and \"#$alias\" does not for value= on a radio button??

 

anyway it's working now that I removed the \" that was wrapped around the value= parameter's
