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
- Collapse posts with specific domains
body matches "/\\.example\\.com/" - Collapse posts that contains the words
body matches "/Guten Morgen/" - Collapse posts with the word facebook that have a space in front and after the word
body matches "//s facebook/s /" - Collapse posts 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 -
trueandfalse. - 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
notor!andor&&oror||
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.
