Radio Button conditional not working

This question may be related to a resolved thread.

So after making the change to the conditional as noted in the thread above.
```
{if  {productline} == vector|helix|prism|matrix}
```
Change to
```
{if  {productline} == "vector|helix|prism|matrix"}
```
The Error went away. Now the value in the condition is false when I set the productline variable to “vector|helix|prism|matrix.” If I change it back to the original it works but then the error from the related post returns. “Notice: Use of undefined constant” Can someone tell me why the conditional is false even though the value of the variable is exactly what its suppose to be for the condition to be true? Thanks in advanced for any suggestions.

Hi sleven1868,

If productline is a custom field then please remove the curly brackets from around it. Also, you posted that you set the productline variable to “vector|helix|prism|matrix.” - notice the fullstop after matrix. Was that a typo? I’m a bit unclear about this being a radio button conditional. Can you clarify where this data is coming from?

Cheers

Greg

Hey greg,

So I’m submitting a form that posts to itself and I use the IN function to grab the values and show data in weblog using dynamic paramters. Here is the form code.

<?php
global $IN;
$application = $IN->GBL('category','POST');
$productline= $IN->GBL('weblog','POST');
$wattage = $IN->GBL('wattage','POST');

?>  
{assign_variable:productline="<?php echo $productline; ?>"}
{assign_variable:application="<?php echo $application; ?>"}
{assign_variable:wattage="<?php echo $wattage; ?>"}

Hey Greg, another thing. I have 2 instances of my test area running. Both running the exact same code. I use the old code for the product line as seen in my first post. I’m displaying the values of the variables right below the Shop By section in the radio group in the test.qnuru.com (broken instance)
```
{if  {productline} == vector|helix|prism|matrix}
```
Works for one instance, throws the Notice: Use of undefined constant error in the other. You can see it happening using the following links.
http://test.qnuru.com/index.php/ShopbyProductLine/—> Click on Helix and then click on “All Product Lines”—> Error

http://vltest.qnuru.com/index.php/ShopbyProductLine/—> Click on Helix and then click on “All Product Lines” —> No Error

When I change it to the new code in test.qnuru.com
```
{if  {productline} == "vector|helix|prism|matrix"}
```
The error goes away but then the conditional doesn’t become true when the value of the variable product_line is set to “vector|helix|prism|matrix”. First, I can only speculate that its a server setting that is causing the error to be shown in one instance on one host but not in the other on another host. It works on my old host even though I cannot see the error, which may or may not be there. Hopefully this is a bit more information to help troubleshoot this issue.

sleven1868,

You may be running into a parsing issue by adding quotes now.
Remove the quotes as you had them before. Your error reporting may show more on this server. So the error may have existed on your other server but you the errors were suppressed.

These are errors I as a user cannot see. Only you as a Superadmin can see them. So if you revert code it will work for me as a user who is not going to see that error

Or consider something like this which will bypass any parsing issues you have assigning a variable
```
{if  "<?php echo $productline; ?>" == "vector|helix|prism|matrix"}
```
