Extra Validation Rules
| Rule | Parameter | Description | Example |
|---|---|---|---|
| valid_date | Yes | Fails if field does not contain a valid date. Any string that strtotime() accepts is valid if you don’t specify an optional parameter that matches a date format. So it is usually necessary to specify the parameter. | valid_date[d/m/Y] |
| valid_json | No | Fails if field does not contain a valid JSON string. | |
| uploaded | No | It works like 'required' but for $_FILES | |
| is_image | No | Fails if the file cannot be determined to be an image based on the mime type. | |
| mime_in | Yes | Fails if the file’s mime type is not one listed in the parameters. | mime_in[image/png,image/jpeg] |
| ext_in | Yes | Fails if the file’s extension is not one listed in the parameters. | ext_in[png,jpg,gif] |
| max_size | Yes | Fails if the uploaded file is larger than the second parameter in kilobytes (kb). | max_size[1024] |
| max_dims | Yes | Fails if the maximum width and height of an uploaded image exceed values. | max_dims[468,60] |
| min_dims | Yes | Fails if the minimum width and height of an uploaded image not meet values. | min_dims[468,60] |
| exact_dims | Yes | Fails if the width and height of an uploaded image has different values. | exact_dims[468,60] |
Use translated error messages
By default, error messages are located in /src/Lang/data.php, you can use your own translation loading a new array data:
