This help page includes a summary of [the Symfony's Expression Language documentation page.](https://symfony.com/doc/current/components/expression_language/syntax.html) ## 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 1. Collapse posts with specific domains `body matches "/\\.example\\.com/"` 2. Collapse posts that contains the words `body matches "/Guten Morgen/"` 3. Collapse posts with the word facebook that have a space in front and after the word `body matches "//s facebook/s /"` 4. 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** - `true` and `false`. - **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 to ``foo ? foo : 'no'``) * ``foo ? 'yes'`` (equal to ``foo ? '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. <table class="table-bordered table-condensed table-striped"> <thead> <tr> <th>Variable</th> <th>Type</th>
