Testing existence of a post/get variable in templates

Wednesday 18 May 2005 2:08:37 am

How can I test, in templates, the existence of a
get/post variable? Using ezhttp I have the template error:

<i>Unknown post/get variable 'optvar'</i>

As example, if a form field is optional,
when not filled , it doesn't appear in POST , and when I try the template code:

...
{section show=is_set(ezhttp( 'optvar', 'post' ))}
    optvar = {ezhttp( 'optvar', 'post')}<br>
{/section}
...

It works well but it returns also the described template error.

Roberto,

You can't avoid that template error when using ezhttp. The code for the operator does a $http->has(Post|Get|Session)Variable() and prints the error in the else branch.

Doing an is_set on the result of ezhttp can't aleviate the problem because the error comes from the ezhttp operator itself.

It annoys me too, but it really isn't a problem with your code, nor in eZ publish's code.
