Validation not work

I had something like that after upgrading to 4.1 CF7.
I went back to version 4.0.1 of CF7

if ($leInput != '') {
	$result->invalidate($tag, "Debe seleccionar por lo menos un producto.");
}

This invalidates if the field is not blank.

LOL, yes!,

but I tried without the conditional and didn’t work.

function cf7_custom_form_validation($result, $tag) {
	$tag = new WPCF7_Shortcode($tag);

	if ($tag->name == 'pedidoFinal') {
		$leInput = isset($_POST[$tag->name]) ? trim($_POST[$tag->name]) : '';

		if ($leInput == '') {
			$result->invalidate($tag, "Debe seleccionar por lo menos un producto.");
		}
	}
	return $result;
}
add_filter( 'wpcf7_validate_text*', 'cf7_custom_form_validation', 20, 2 );

Didn’t work ??

Give it a priority higher than the default validation filter for text*.

add_filter( 'wpcf7_validate_text*', 'cf7_custom_form_validation', 20, 2 );

to

add_filter( 'wpcf7_validate_text*', 'cf7_custom_form_validation', 9, 2 );

Now works!

Thanks Takayuki.

Please, update the code in your site, because I copied it from there.

Marked as resolved ??

Good work. I don’t know which page you copied it from though.

It’s Developer’s Cookbook. Not for copying to use blindly.
