CodeIgniter extended rules

A set of useful form validation rules, focused on file uploading (and some more). English corrections and other languages are welcome.

Written by Joseba Juaniz (@Patroklo) and Jeroen van Meerendonk (@jeroen_bz). Original code written by devbro ([email protected]).

Requirements

Codeigniter 3.x Php 5.2 or above

Installation

Just put copy the files into your server using the same folder structure. If you already have an english language file, open it and add the content of /application/language/english/form_validation_lang.php, and do the same with the other languages.

Rules

Use them as the other rules.

• file_required Checks if the a required file is uploaded.
• file_size_max[size] Returns FALSE if the file is bigger than the given size.
• file_size_min[size] Returns FALSE if the file is smaller than the given size.
• file_allowed_type[type] Tests the file extension for valid file types. You can put a group too (image, application, word_document, code, zip).
• file_disallowed_type[type] Tests the file extension for no-valid file types
• file_image_maxdim[x,y] Returns FALSE if the image is smaller than given dimension.
• file_image_mindim[x,y] Returns FALSE if the image is bigger than given dimension.
• file_image_exactdim[x,y] Returns FALSE if the image is not the given dimension.
• is_exactly[list] Check if the field's value is in the list.
• is_not[list] Check if the field's value is not permitted.
• valid_hour[type] Check if the field's value is a valid hour. [24H or 12H]
• valid_date[date_format] Check if the field's value has a valid format. If not provided with a format, it will use the standard value.
• valid_range_date[date_format] Check if the field's value has a valid range of two date formats. If not provided with a format, it will use the standard value.
• valid_geopos[latitude;longitude] Check if latitude and longitude parameters are valid.
• valid_multiple_geopos[json made of array of latitude;longitude] Check if latitude and longitude parameters are valid.
