Advanced Content Filter Help
The advanced Content Filter uses Symfony's Expression Language. This help page includes a summary of the Symfony's Expression Language documentation page.
Basics
The advanced content filter matches each post that is about to be displayed against each enabled rule you set.
A rule is a boolean expression that should return either true
or false
depending on post variables.
If the expression using a post variables returns true
, the post will be collapsed and the matching rule name will be displayed above the collapsed content.
A post will be collapsed if at least one rule matches, but all matching rule names will be displayed above the collapsed content.
Examples
- To block specific domains
body matches "/\\.example\\.com/"
- To block everything that contains the words
body matches "/Guten Morgen/"
- To block every occurence of the word facebook with a space in front and after the word
body matches "//s facebook/s /"
- To colapse every post that contains more than 1 image
body matches "/(?:(?:(?:\\[url(?:=.*)?\\])?\\[img(?:=.*)?\\].*\\[\\/img\\]\\s*(?:\\[\\/url\\])?)\\s*){2}/"
Expression Syntax
Supported Literals
- strings - single and double quotes (e.g.
'hello'
). - numbers - e.g.
103
. - arrays - using JSON-like notation (e.g.
[1, 2]
). - hashes - using JSON-like notation (e.g.
{ foo: 'bar' }
). - booleans -
true
andfalse
. - null -
null
.
A backslash (\
) must be escaped by 2 backslashes (\\
) in a string and 4 backslashes (\\\\
) in a regex::
"a\\b" matches "/^a\\\\b$/"
Control characters (e.g. \n
) in expressions are replaced with whitespace. To avoid this, escape the sequence with a single backslash (e.g. \\n
).
Supported Operators
The component comes with a lot of operators:
Arithmetic Operators
+
(addition)-
(subtraction)*
(multiplication)/
(division)%
(modulus)**
(pow)
Bitwise Operators
&
(and)|
(or)^
(xor)
Comparison Operators
==
(equal)===
(identical)!=
(not equal)!==
(not identical)<
(less than)>
(greater than)<=
(less than or equal to)>=
(greater than or equal to)matches
(regex match)
To test if a string does not match a regex, use the logical not
operator in combination with the matches
operator:
not ("foo" matches "/bar/")
You must use parenthesis because the unary operator not
has precedence over the binary operator matches
.
Logical Operators
not
or!
and
or&&
or
or||
String Operators
~
(concatenation)
For example: firstName ~ " " ~ lastName
Array Operators
in
(contain)not in
(does not contain)
For example: user.group in ["human_resources", "marketing"]
Numeric Operators
..
(range)
For example: user.age in 18..45
Ternary Operators
foo ? 'yes' : 'no'
foo ?: 'no'
(equal tofoo ? foo : 'no'
)foo ? 'yes'
(equal tofoo ? 'yes' : ''
)
Supported variables
Here are a sample of the available variables you can use in your expressions. You can also retrieve the variables of a specific post by pasting its URL below the rule list.
