New Filter – Uppercase first letter and make Title case

[katw]

Hi Ally,

I would like to create two custom field filters.

1. change first letter in the field to UPPERCASE (for NAME FIELDS for example)
2. change first letter of each discrete word to UPPERCASE (for address and title fields)

Filter 2 (Title-case) use-case example: street address field with field data “unit 6/77 stone st” becomes “Unit 6/77 Stone St” and “1234 pacific hwy” becomes “1234 Pacific Hwy” etc

For filter 1 (Uppercase first word) use-case: first name field “sue-anne” becomes “Sue-anne”

I looked but couldn’t see an example to follow.

Any suggestions?

Don’t worry, I will do this client side.

BTW might be worth adding these filters to future QuForm updates.

And publishing a “how to make your own filter” as you have done for custom validators.

Just an idea.

I tried to create a new PHP filter for uppercase first letter.

I modelled the code on your TRIM example and uploaded the new filter to the QUFORM > FILTERS directory.

Unfortunately it didn’t work.

Am guessing an Initialisation routine knows about the filters installed and didn’t like my addition. Or I have missed doing an important step.

You probably don’t want to help with this solution as I am modifying your install files (which makes it problematic for me at time of upgrading).

BUT if you did want to help here is the code I added to a file called UpperFirstLetter.PHP

<?php

/**
 * @copyright Copyright (c)2018 ThemeCatcher
 */
class Quform_Filter_UpperFirstLetter extends Quform_Filter_Abstract
{
    /**
     * Makes first letter of value uppercase
     *
     * If the value provided is not a string, the value will remain unfiltered
     *
     * @param   string  $value  The value to filter
     * @return  string          The filtered value
     */
    public function filter($value)
    {
        if ( ! is_string($value)) {
            return $value;
        }

        return ucfirst($value);
    }

    public static function getDefaultConfig()
    {
        $config = apply_filters('quform_default_config_filter_UpperFirstLetter', array());

        $config['type'] = 'UpperFirstLetter';

        return $config;
    }
}

Found I should also add my new filter definition to function getFilters()

Fantastic, I will follow that same format to build a title case filter too.

Thanks again.
