i have the function below on function.php<\/p>\n

\/**\n * Set a minimum order amount for checkout\n *\/\n add_action( 'woocommerce_checkout_process', 'wc_minimum_order_amount' );\n add_action( 'woocommerce_before_cart' , 'wc_minimum_order_amount' );\n\nfunction wc_minimum_order_amount($min_amount) {\n\/\/ Set this variable to specify a minimum order value\n\/\/$minimum = $('#amount').val(); \n\/\/$minimum = 30; \n\n$minimum = $min_amount; \n\nif ( WC()->cart->total < $minimum ) {\n\n    if( is_cart() ) {\n\n        wc_print_notice( \n            sprintf( 'Your current order total is %s \u2014 you must have an order with a minimum of %s to place your order.' , \n                wc_price( WC()->cart->total ), \n                wc_price( $minimum )\n            ), 'error' \n        );\n\n    } else {\n\n        wc_add_notice( \n            sprintf( 'Your current order total is %s \u2014 you must have an order with a minimum of %s to place your order.' , \n                wc_price( WC()->cart->total ), \n                wc_price( $minimum )\n            ), 'error' \n        );\n\n    }\n}\n}<\/code><\/pre>\n
Also, i have an input field and a button <\/p>\n
<form>\n <input type="text" id="amount" name="min_amount_ID"\/>\n<input type="button" onclick="wc_minimum_order_amount(this.form.min_amount_ID.value)" class="min_amount"\/>\n<\/form><\/code><\/pre>\n
How can i call the function wc_minimum_order_amount() from function.php file on click button?
\nOr how i can use the result of the script below inside wc_minimum_order_amount() function and assign it as a result to the variable $minimum ?<\/p>\n
   <script type="text\/javascript">\n $(document).ready(function(){\n   $('.min_amount').on('click', function(){\n    var text_val = $('#amount').val();\n   \/\/alert(text_val );\n      });\n });\n<\/script><\/code><\/pre>\n","protected":false},"template":"","class_list":["post-12056477","topic","type-topic","status-publish","hentry","topic-tag-function-php"],"jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic\/12056477","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic"}],"about":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic\/12056477\/revisions"}],"wp:attachment":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/media?parent=12056477"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
