ezhttp

Summary

Returns GET, POST and session variables.

Usage

ezhttp( name [, type [, check_existence ] ] )

Parameters

NameTypeDescriptionRequired
name string The HTTP variable that should be fetched. Yes.
type string Source of variable. Default is is HTTP POST. No.
check_existence mixed If the specified directive should be checked for existence. No.

Returns

Variable value

Description

This operator makes it possible to inspect the contents of HTTP variables (POST, GET or session variables). The "type" parameter can be used to specify which type of variable that should be extracted. The following options are available:

  • post (POST variable)
  • get (GET variable)
  • session (session variable)

The "check_existence" parameter can be set to TRUE or the string "hasVariable" in order to check if a directive is actually set. In this case, the operator will return either TRUE or FALSE. Note that using the "ezhttp_hasvariable" operator is a better option.

Examples

Example 1

{ezhttp( 'search' )}

Returns the "search" POST variable.

Example 2

{ezhttp( 'image', 'get' )}

Returns the "image" GET variable.

Example 3

{ezhttp( 'user_id', 'session' )}

Returns the "user_id" session variable.

    It's a little too bad there's no way to avoid a warning when the variable we're fetching is not set ...

        using 3.7.4 and getting an error as well. even testing for the existence fo a get/post var throws an error:
        {if ezhttp( 'myvar', 'get' ) } => returns false, but throws error
        the same with {if is_set( ezhttp( 'myvar', 'get' ) )}
        its a bug in my opinion..

      you can use in 3.9 (trunk) like:
      ezhttp_hasvariable( 'getVar','get' )
      or
      ezhttp( 'getVar','get','hasVariable' )

    It would be nice if the ezhttp operator could return all vars in the array specified. ezhttp(GET) would return all $_GET vars for example.

  • ezhttp is not working if caching is turned on.

    i put
    {set-block scope=root variable=cache_ttl}0{/set-block}
    to all templates, because in other way ezhttp will return the same value...

    Returns:
    Variable value or null

    test for non-existence using
    {if not(ezhttp('test'))}
    or
    {if ezhttp('test')|null()}

    Is it possible to set session variables as well?
