[Resolved] Comparing a portion of a string in Conditional output

Regarding conditional output: Is there a way to test just a portion of a string using conditional statements ("wpv-conditional if")?
For example if the field contains values like:
CX24, CX56, etc. and I want the conditional to compare just the first two characters of that string ("CX") is there an operator or expression to do that?

Hi Briana

The only comparison operators available are equals, not equals, and greater/less than (https://toolset.com/documentation/user-guides/conditional-html-output-in-views/#comparison-operator).

So if you want a partial match comparison you'll need to write a custom function or shortcode to perform the comparison and register that for use in the wpv-conditional shortcode (see https://toolset.com/documentation/user-guides/conditional-html-output-in-views/using-shortcodes-in-conditions/#checking-custom-shortcodes).

Here's a custom shortcode that you might want to adapt to your needs (don't forget to register it):

add_shortcode( 'contains', function( $atts ){

	global $post;
	$return = -1;

	$atts = shortcode_atts( [ 'string' => '', 'field' => null ], $atts );

	if ( isset( $atts['field'] ) ) {

		$key = 'wpcf-' . $atts['field'];

		$field = get_post_meta( $post->ID, $key, true );

		$return = strpos( $field, $atts['string'] );

		if ( $return === false ) {
			$return = -1;
		}
	}
	return $return;

});

You pass a field slug for the custom field to test and a string for what you are searching for, e.g.

[wpv-conditional if="( '[contains field='arbitrary-text' string='ABC']' gte '0' )"]Contains ABC[/wpv-conditional]
