Execute couch tag within PHP?

I'm developing a literature request form on my company's website. Its an all-in-one PHP form that validates on the server side. I've hit a roadblock in development and was looking for some guidance.

Essentially I have couch looping our catalogs by folder or category. I'm collecting the literature quantities in the form and putting them into an array. I've hit a point where I need to be able to output the catalog name into the array variable in PHP. Here is the full code I'm using (trimmed down to show general function):

Code: Select all
<?php require_once( 'couch/cms.php' ); ?>
<?php
// Instatiate variables
$name = "";
$nameClass = "field";
$nameMessage = "";
$formtitle = "";

$companyMessage = "";
$address = "";
$addressClass = "field";

$cityMessage = "";

<?php COUCH::invoke(); ?>


I'm interested in getting couch to output the catalog names as the key for the array variable order. You can see it in the code as
Code: Select all
value="<?php echo $order['<cms:show pdf_name />'];?>"
This way if the form has invalid fields, the user won't lose the quantities that they've already entered. We've all had this happen when filling out a form online, and it is not a good user experience.

What are my options?

There is an order of operations between Couch and PHP. Regular old PHP tags
Code: Select all
<?php echo 'something'; ?>
are executed first, before Couch is instantiated.

PHP inside of the Couch tag
Code: Select all
<cms:php>echo 'something';</cms:php>
is executed after Couch is up and running and therefore has access to all of the Couch variables. For this reason, it's generally better to use the <cms:php> tag, even though it's probably less familiar to you.
Code: Select all
<cms:php>echo "<cms:show my_variable />";</cms:php>

To make a variable created in PHP into a Couch variable, there is a Couch function:
Code: Select all
$CTX->set( 'my_couch_variable', $my_php_variable );
Now the variable generated by your PHP code can be used in your Couch code.

To go in the other direction, use $CTX->get().
Code: Select all
$my_php_variable = $CTX->get( 'my_couch_variable' );


I admit that my eyes glazed over while reading your code :), so I might be a little vague on your exact needs, but I hope these details about combining Couch and PHP give you the help you need. Please say so if I missed the point.

Thanks Tim! My apologies for the lengthy code, but I just wanted to post the whole "shabang" so that everyone would have the full story. My eyes glaze over when I look at it too. :lol:

You made some good suggestions. I'll try it out and let you know how it goes. Thanks again!

Hmmm. I'm not getting the function to work. Are these function used like this?

Code: Select all
<cms:php> $CTX->set( 'my_couch_variable', $name ); </cms:php>


I was trying to set it to any existing variable with a value to test it. Although it gives me the following error:

Fatal error: Call to a member function set() on a non-object


This code:
Code: Select all
<?php $CTX->set( 'my_couch_variable', $name ); ?>


...doesn't seem to set any variable couch. When I call it like so:

Code: Select all
<cms:show my_couch_variable />


Please excuse my ignorance if I'm doing this wrong. Like you said, I'm much more familiar with PHP syntax than these custom couch tags. I can get by using the standard couch tags, but I'm stumped in this situation.

Sorry. That's my mistake. I left out a part. Try
Code: Select all
<cms:php>
global $CTX;
$CTX->set( 'my_couch_variable', $name );
 </cms:php>

No problem. Thanks for the follow-up. I tried it with the global variable as you pointed out, but unfortunately I couldn't get it to work.

I think I'm going to just make a separate SQL table with the information I need to pull and loop it traditionally outside of couch. Thanks again for your help. :)
