I'd like to replace default "Read more" button text on products conditionnaly.
example: if $product_type = 'simple' && category = 'services' return mystring
So fare, I have :
add_filter( 'woocommerce_product_add_to_cart_text' , 'custom_woocommerce_product_add_to_cart_text' );
function custom_woocommerce_product_add_to_cart_text() {
global $product;
$product_type = $product->product_type;
switch ( $product_type ) {
case 'external':
return __( 'External text', 'woocommerce' );
break;
case 'grouped':
return __( 'Grouped text', 'woocommerce' );
break;
case 'simple':
return __( 'Simple text', 'woocommerce' );
break;
case 'variable':
return __( 'Variable text', 'woocommerce' );
break;
default:
return __( 'Read more', 'woocommerce' );
}
}

Reset to default 0First you should check if you're actually replacing Read more, you can also remove the default: and just make sure you return the original value passed to the filter.
If you specifically want to use switch you can use a less commonly used pattern for evaluating statements by setting switch(true) and then enclosing the if statement in parenthesis for the case
To get/check the categories, there's a couple ways to do this, in my example below i'm using get_the_terms to get all the categories, and then mapping all the slugs to an array, so you can use in_array (i removed the other case statements for simplicity of the example code):
add_filter( 'woocommerce_product_add_to_cart_text', 'custom_woocommerce_product_add_to_cart_text', 10 );
function custom_woocommerce_product_add_to_cart_text( $text ) {
// First make sure that we are only replacing 'Read more' as some situations based on product
// this can be "Select some options" or "Add to cart"
$wc_read_more = __( 'Read more', 'woocommerce' );
if( $text !== $wc_read_more ){
return $text;
}
global $product;
$product_type = $product->product_type;
$product_terms = get_the_terms( $product->ID, 'product_cat' );
// Convert to array of all the slugs
$pc_slugs = array_map( function($term){ return $term->slug; }, $product_terms );
switch ( true ) {
case ( $product_type === 'simple' && in_array( 'services', $pc_slugs ) ):
return __( 'Simple text', 'woocommerce' );
break;
}
return $text;
}
Another option would be to use has_term instead of mapping slugs to an array:
add_filter( 'woocommerce_product_add_to_cart_text', 'custom_woocommerce_product_add_to_cart_text', 10, 2 );
function custom_woocommerce_product_add_to_cart_text( $text, $that ) {
// First make sure that we are only replacing 'Read more' as some situations based on product
// this can be "Select some options" or "Add to cart"
$wc_read_more = __( 'Read more', 'woocommerce' );
if( $text !== $wc_read_more ){
return $text;
}
global $product;
$product_type = $product->product_type;
switch ( true ) {
case ( $product_type === 'simple' && has_term( 'services', 'product_cat', $product->ID ) ):
return __( 'Simple text', 'woocommerce' );
break;
}
return $text;
}
Also want to mention you said if $product_type = 'simple' && category = 'services', in PHP a single = is assignment, meaning "set equal to", it's good to get in the habit of always using == or === (strict) even if just explaining in laments terms
