Unit operators

si

Handles unit display of values, most often used for showing sizes of files but can also be used for displaying units on other items such as meters, grams etc.
The operator reads two parameters. The first tells the kind of unit type we're dealing with, for instance: byte, length.
The second determines the behaviour of prefixes and is optional.

{1025|si(byte)}

 {1025|si(byte,binary)}

 {1025|si(byte,decimal)}

 {1025|si(byte,none)}

 {1025|si(byte,auto)}

 {1025|si(byte,mebi)}

This is a complete list of all the operators you can use in Exponential templates. Most operators are native to eZ template (general), some are specific for Exponential.

Locale

l10n

Localizes values, e.g.

{42.50|l10n(currency)}

Allowed types are: datetime, shortdatetime, time, shorttime, date, shortdate, currency or number.

Dates

datetime

Formats dates and times according to formats defined in datetime.ini. Custom formats in the template itself are also possible. E.g.

{$date|datetime(mydate)}, {$date|datetime(custom,"%m %y")}

currentdate

Returns the timestamp of the current datetime. E.g.

{currentdate()}

Debug

attribute

Helper attribute to print available methods in objects and arrays, by default it only shows the array keys and object
attribute names but by passing show as parameter it will fetch the values.
The second parameter can be used to controlled the number of children to expand, default is no limit which may give problems with values that loop. The returned result is an HTML table unless false() is passed as the third parameter. E.g.

{$node|attribute(show)}, {$node|attribute(show,2,false)}

Output washing

wash

General character/string washing operator. The washing type is the first parameter:

• xhtml (default) replaces special HTML characters
• email replaces '@' and '.' with '_at_' and '_dot_', as specified in template.ini
• pdf replaces whitespace characters in postscript codes

Text operations

concat

Concatenates values to one string. If you give it an array, it will concatenate the elements of the array. E.g.

{concat('/var/',$node.node_id,'/')}

autolink

Converts all known links in a text to links that can be clicked. E.g.

{"Some links: ftp://ftp.mysite.com me@mysite.com http://www.mysite.com"|autolink}

ezini

The ezini() operator enables access to the variables in the *.ini files. It takes three arguments:

• a section in the ini file (as put between [] brackets)
• the variable itself
• optional: the .ini file, if other than site.ini

{ezini('[section]','[variable]','[ini file]')}

For example to differentiate between locale settings, use template code similar to the follwing:

{section show=eq(ezini('RegionalSettings','Locale'),"eng-GB")}

... display por-PT link

{section-else}

... display eng-GB link

{/section}

Exponential kernel operators

ezurl

Makes sure that the url works for both virtual hosts and non-virtual host setups.

ezroot

he last parameter value. E.g.

{and(false(),false(),true(),false())}

returns false.

choose

Uses the input count to pick one of the parameter elements. The input count equals the parameter index. E.g.

{0|choose("a","b","c")} returns "a".

contains

Returns true if the first parameter value is found in the input value, which must be an array.
Currently it works the same way as the PHP function in_array() but it may later be extended to support more advanced matching. E.g.

$array|contains($myvalue)
