Built-in template operators #

Part 8, reference 23. This page lists the operators of a running Exponential 6 installation, grouped by the PHP class that implements them. The list was produced by asking the template engine of a demo installation for every registered operator (October 2026), so it is what templates can call, not what an old manual said. Extensions add their own operators; those appear only when the extension is active. How each operator is used, with examples, is in the designer help (Operators overview and Operator reference).

Strings (eZTemplateStringOperator) #

break, chr, count_chars, count_words, downcase, ord, pad, shorten, simplify, trim, upcase, upfirst, upword, wash, wrap

wash escapes a value for HTML (or, with a parameter, for javascript, email and other targets). Every value that did not come from your own template text goes through it.

More string functions (eZTemplateStringsOperator) #

PHP's string functions under their own names, among them sprintf, number_format, str_contains, str_starts_with, str_ends_with, strlen, substr_count, substr_replace, strtr, stripos, lcfirst, html_entity_decode, htmlentities, levenshtein, similar_text, soundex, metaphone, str_split, str_word_count, chunk_split, bin2hex, hex2bin, quoted_printable_encode and the comparison functions (strcmp, strcasecmp, strnatcmp ...). Also nl2br, strip_tags, urlencode, rawurlencode, urldecode, serialize, unserialize and getenv.

Arrays (eZTemplateArrayOperator) #

append, array, array_append, array_merge, array_prepend, array_sum, begins_with, compare, contains, ends_with, explode, extract, extract_left, extract_right, hash, implode, insert, merge, prepend, remove, repeat, replace, reverse, unique

Logic and control (eZTemplateLogicOperator, eZTemplateControlOperator) #

and, or, not, eq, ne, lt, le, gt, ge, choose, true, false, null; cond, first_set

Arithmetic (eZTemplateArithmeticOperator) #

sum, sub, mul, div, mod, inc, dec, abs, ceil, floor, round, int, float, min, max, count, rand, roman

Types (eZTemplateTypeOperator) #

is_array, is_boolean, is_integer, is_float, is_numeric, is_string, is_object, is_class, is_null, is_set, is_unset, get_type, get_class

Dates and locale (eZTemplateLocaleOperator) #

l10n, locale, datetime, currentdate, maketime, makedate, gettime

URLs, designs, settings, request (the URL operator class) #

ezurl, ezroot, ezdesign, ezimage, exturl, ezsys, ezini, ezini_hasvariable, ezhttp, ezhttp_hasvariable; for multisite installations also siteaccess_url. ezurl and the image and design operators print their result quoted unless given 'no'.

Translation (eZi18nOperator) #

i18n, x18n, d18n: {'Text'|i18n( 'extension/myext' )} with your extension's context.

Icons (eZWordToImageOperator) #

icon, icon_info, class_icon, classgroup_icon, action_icon, mimetype_icon, flag_icon, wordtoimage

Access (eZTemplateRoleOperator, ezjscore) #

has_role, has_role_id, has_any_role, has_role_by_user, has_role_by_user_id, has_policy, has_policy_by_user, has_access_to_limitation. For "may the current user do X", prefer the fetch function fetch( 'user', 'has_access_to', ... ) (eZUser and access checks).

Encoding and the packer (ezjscore) #

json_encode, node_encode, xml_encode; ezcss, ezcss_load, ezcss_require, ezcssfiles, ezscript, ezscript_load, ezscript_require, ezscriptfiles (Theme assets, the packer and CSP).

Other kernel operators #

fetch, fetch_alias (fetch functions); attribute, dump (inspect a value while debugging); concat, indent; si (units); crc32, md5, rot13; texttoimage, imagefile; expinfo (installation and extension information); ezpreference; ezmodule, module_params; topmenu, treemenu, content_structure_tree; eztoc, autolink, simpletags, alphabet, month_overview, ezpackage; installation_name, is_production_system, exp_environment, exp_environment_badge; csp_nonce (the Content Security Policy's nonce, for the rare inline script that must stay).

Operators of shipped extensions #

Some operators that templates use often come from extensions shipped with the kernel, and exist only when those are active: ezpagedata, ezpagedata_set, ezpagedata_append, ezkeywordlist and ezarchive (ezwebin and ezdemo), ezcreateclasslistgroups (ezwt), exp_config (expui), and the ezjscore operators above.

Listing them yourself #

The list differs per installation, because extensions add operators. To see yours, render a template with the debug output on and an unknown operator: the error names the operator. Or ask the Extension point survey (/setup/radsurvey), which lists the operators each active extension registers.
