FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Installation
Add the following to your composer.json file.
Example Usage
The first thing you need to do is give us an array of values to validate against. In this case you have given us the $_POST vars. Now you can set the rules and filters for each field.
Field names can be an array by adding brackets to the end ie. 'name[]'. They can also be multi-dimensional arrays such as 'name[first]', or 'name[players][]', or 'name[parent][child]', etc. The important thing to remember is that you must always use the exact name given here when referencing them in other methods.
Rules and filters are either '|' (single pipe) delimited, or you can make them an array. Custom messages can be specified by making it an array($rule => $message, ...). Parameters are comma-delimited, and placed within '[]' two brackets. The available options are:
- 'remote[rule]' - Set
$validator->rules['rule'] = function($value){}to determine the validity of a submitted value. The function should return a boolean true or false. - 'default' - A default value if the field is empty, or not even set.
- 'required' - This field must have a value, and cannot be empty.
- 'equalTo[field]' - Must match the same value as contained in the other form field.
- 'notEqualTo[field]' - Must NOT match the same value as contained in the other form field.
- Numbers:
- 'number' - Must be a valid decimal number, positive or negative, integer or float, commas okay. Defaults to 0.
- 'integer' - Must be a postive or negative integer number, no commas. Defaults to 0.
- 'digits' - Must be a positive integer number, no commas. Defaults to 0.
- 'min[number]' - Must be greater than or equal to [number].
- 'max[number]' - Must be less than or equal to [number].
- 'range[min, max]' - Must be greater than or equal to [min], and less than or equal to [max].
- Strings:
- 'alphaNumeric' - Alpha (a-z), numeric (0-9), and underscore (_) characters only.
- 'minLength[integer]' - String length must be greater than or equal to [integer].
- 'maxLength[integer]' - String length must be less than or equal to [integer].
- 'rangeLength[minLength, maxLength]' - String length must be greater than or equal to [minLength], and less than or equal to [maxLength].
- 'minWords[integer]' - Number of words must be greater than or equal to [integer].
- 'maxWords[integer]' - Number of words must be less than or equal to [integer].
- 'rangeWords[minWords, maxWords]' - Number of words must be greater than or equal to [minWords], and less than or equal to [maxWords].
- 'pattern[regex]' - Must match the supplied ECMA Javascript compatible [regex].
- 'date' - Must be a valid looking date. No particular format is enforced.
- 'email' - Must be a valid looking email.
- 'url' - Must be a valid looking url.
- 'ipv4' - Must be a valid looking ipv4 address.
- 'ipv6' - Must be a valid looking ipv6 address.
- 'inList[1,2,3]' - Must be one of a comma-separated list of acceptable values.
- 'noWhiteSpace' - Must contain no white space.
- Filters:
- 'singleSpace' - Removes any doubled-up whitespace so that you only have single spaces between words.
- 'trueFalse' - Returns a 1 (true) or 0 (false) integer.
- 'yesNo' - Returns a 'Y' or 'N' value.
To see if the $_POST array you gave us meets all of your requirements:
The $vars returned are all trim()ed and filtered, ready for you to process as you see fit. From here, the best thing to do is use our BootPress Form Component, but if you have any better ideas then you can determine whether or not the $validator->required('field'), get the submitted $validator->value('field'), check if there was a $validator->error('field'), get the data-rule-... $validator->rules('field') attributes, and the data-msg-... $validator->messages('field') attributes, find the $validator->id('field') we assigned, and set the $validator->jquery('#form') javascript when creating your form and fields.
All of the above is just assuming you are using this component to validate submitted form data, but it is equally well suited to validate anything on the side as well. The static methods we provide (and use ourselves) are:
The value you want to validate always comes first, and any parameters come second - lest you be confused.
