voidThrows
Cake\Core\Exception\CakeExceptionif attempting to clobber existing config
_configRead() ¶ protected
_configRead(string|null $key): mixedReads a config key.

voidThrows
Cake\Core\Exception\CakeExceptionif attempting to clobber existing config
_formatAttribute() ¶ protected
_formatAttribute(string $key, mixed $value, bool $escape = true): stringFormats an individual attribute, and returns the string value of the composed attribute. Works with minimized attributes that have the same value as their name such as 'disabled' and 'checked'
Parameters

string$key The name of the attribute to create
-
mixed$value The value of the attribute to create.
-
bool$escape optional Define if the value must be escaped
Returns
stringadd() ¶ public
add(array<string> $templates): $thisRegisters a list of templates by name
Example:
$templater->add([
'link' => '<a href="{{url}}">{{title}}</a>'
'button' => '<button>{{text}}</button>'
]);Parameters
-
array<string>$templates An associative list of named templates.
Returns
$thisaddClass() ¶ public
addClass(mixed $input, array<string>|string|false|null $newClass, string $useIndex = 'class'): array<string>|string|nullAdds a class and returns a unique list either in array or space separated
Parameters
-
mixed$input The array or string to add the class to
-
array<string>|string|false|null$newClass the new class or classes to add
-
string$useIndex optional if you are inputting an array with an element other than default of 'class'.
Returns
array<string>|string|nullconfigShallow() ¶ public
configShallow(array<string, mixed>|string $key, mixed|null $value = null): $thisMerge provided config with existing config. Unlike config() which does
a recursive merge for nested keys, this method does a simple merge.
Setting a specific value:
$this->configShallow('key', $value);Setting a nested value:
$this->configShallow('some.nested.key', $value);Updating multiple config settings at the same time:
$this->configShallow(['one' => 'value', 'another' => 'value']);Parameters
-
array<string, mixed>|string$key The key to set, or a complete array of configs.
-
mixed|null$value optional The value to set.
Returns
$thisformat() ¶ public
format(string $name, array<string, mixed> $data): stringFormat a template string with $data
Parameters
-
string$name The template name.
-
array<string, mixed>$data The data to insert.
Returns
stringThrows
InvalidArgumentExceptionIf template not found.
formatAttributes() ¶ public
formatAttributes(array<string, mixed>|null $options, array<string>|null $exclude = null): stringReturns a space-delimited string with items of the $options array. If a key
of $options array happens to be one of those listed
in StringTemplate::$_compactAttributes and its value is one of:
- '1' (string)
- 1 (integer)
- true (boolean)
- 'true' (string)
Then the value will be reset to be identical with key's name. If the value is not one of these 4, the parameter is not output.
'escape' is a special option in that it controls the conversion of attributes to their HTML-entity encoded equivalents. Set to false to disable HTML-encoding.
If value for any option key is set to null or false, that option will be excluded from output.
This method uses the 'attribute' and 'compactAttribute' templates. Each of
these templates uses the name and value variables. You can modify these
templates to change how attributes are formatted.
Parameters
-
array<string, mixed>|null$options Array of options.
-
array<string>|null$exclude optional Array of options to be excluded, the options here will not be part of the return.
Returns

$this->getConfig();Reading a specific value:
$this->getConfig('key');Reading a nested value:

$this->getConfig('some-key', 'default-value');Parameters
-
string|null$key optional The key to get or null for the whole config.
-
mixed$default optional The return value when the key does not exist.
Returns
mixedgetConfigOrFail() ¶ public
getConfigOrFail(string $key): mixedReturns the config for this specific key.
The config value for this key must exist, it can never be null.
Parameters
-
string$key The key to get.
Returns
