  1. A custom URL input from the user, it Save Products as Meta
  2. If any such URL set is not empty, remove the add_to_cart button with the custom link and the place in the button.
  3. If not, then it would have been used to add a fall-back add to cart button and in one form

    How to find the code here Used to be -. 

      ADD_ACTION ('init', array ($ this, 'woocommerce_custom_add_to_cart_remove_add_to_cart')); // goes Series creator function woocommerce_custom_add_to_cart_remove_add_to_cart () {remove_action ( 'woocommerce_single_product_summary', 'woocommerce_template_single_add_to_cart', 30); Remove_action ('woocommerce_simple_add_to_cart', 'woocommerce_simple_add_to_cart', 30); Remove_action ('woocommerce_grouped_add_to_cart', 'woocommerce_grouped_add_to_cart', 30); Remove_action ('woocommerce_variable_add_to_cart', 'woocommerce_variable_add_to_cart', 30); Remove_action ('woocommerce_external_add_to_cart', 'woocommerce_external_add_to_cart', 30); Add_action ('woocommerce_single_product_summary', array ($ this, 'woocommerce_custom_add_to_cart_custom_button'), 30); Add_action ('woocommerce_simple_add_to_cart', array ($ this, 'woocommerce_custom_add_to_cart_custom_button'), 30); Add_action ('woocommerce_grouped_add_to_cart', array ($ this, 'woocommerce_custom_add_to_cart_custom_button'), 30); Add_action ('woocommerce_variable_add_to_cart', array ($ this, 'woocommerce_custom_add_to_cart_custom_button'), 30); Add_action ('woocommerce_external_add_to_cart', array ($ this, 'woocommerce_custom_add_to_cart_custom_button'), 30); } Function woocommerce_custom_add_to_cart_custom_button () {global $ post, $ product; If ($ this-> woocommerce_custom_add_to_cart_get_cartURL)! = '') echo '& lt; form name = "custom_cart_button" method = "post" action = " '. $ this- & gt; woocommerce_custom_add_to_cart_get_cartURL ().'

php - How can I cram 6+31 numeric characters into 22 alphanumeric characters? -

-
I have a 6 digit number and a 31-digit number (such as "234536" and "201103231043330478311223582826") that I The API needs to be crawled in the same 22-character alphanumeric field that uses PHP. I tried to convert each one to 32 (using custom code could not handle the base_convert () large number) and to connect with a single-character delimiter, but It only gives me 26 characters This is a restore API, so the letters should be URI-protected. I would like to do a database table cross with two references without reference to another reference value, if possible, any suggestions? Instead use a radix of 62. This will give you 22 characters for the top, 3.35 for the pre and 17.3 for the next. & gt; & Gt; & Gt; Math.log (10 ** 6) /math.log (62) 3.3474826039165504 & gt; & Gt; & Gt; Math.log (10 ** 31) /math.log (62) 17.295326786902177

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i...
