Here’s a complete working example: public class Person { public string Name { get; set; } } class Program { static void PropertySet(object p, string propName, object value) { Type t = p.GetType(); PropertyInfo info = t.GetProperty(propName); if (info == null) return; if (!info.CanWrite) return; info.SetValue(p, value, null); } static void PropertySetLooping(object p, string propName, … Read more
This tutorial might help you. The most efficient way of saving IPv4 addresses is with an INT field (not VARCHAR as you might expect). You convert them using PHP’s ip2long and back using either MySQL’s INET_NTOA function or PHP’s long2ip function. If you need to store IPv6, you’ll want to use a BINARY field instead … Read more
What you can do if you don’t find the guilty as explained on my comment is to use the following (using here a highest hook priority if some other code is already using those hooks): add_filter( ‘woocommerce_default_address_fields’, ‘customising_checkout_fields’, 1000, 1 ); function customising_checkout_fields( $address_fields ) { $address_fields[‘first_name’][‘required’] = true; $address_fields[‘last_name’][‘required’] = true; $address_fields[‘company’][‘required’] = true; … Read more
Because it breaks encapsulation — this is why most people use accessors heavily. However, if you think it’s the right solution for your task, ignore it (meaning the strict encapsulation complaints) and do what’s right for your project. Don’t let the OO nazis tell you otherwise.
In java, fields are not polymorphic. Father father = new Son(); System.out.println(father.i); //why 1? Ans : reference is of type father, so 1 (fields are not polymorphic) System.out.println(father.getI()); //2 : overridden method called System.out.println(father.j); //why 10? Ans : reference is of type father, so 2 System.out.println(father.getJ()); //why 10? there is not overridden getJ() method in … Read more
Setting a form element to disabled will stop it going to the server, e.g.: <input disabled=”disabled” type=”text” name=”test”/> In javascript it would mean something like this: var inputs = document.getElementsByTagName(‘input’); for(var i = 0;i < inputs.length; i++) { if(inputs[i].style.display == ‘none’) { inputs[i].disabled = true; } } document.forms[0].submit(); In jQuery: $(‘form > input:hidden’).attr(“disabled”,true); $(‘form’).submit();
I attached an on(‘change’) event to the input you want to have trailing 0’s $(‘.number-input’).on(‘change’, function(){ $(this).val(parseFloat($(this).val()).toFixed(2)); }); It just takes the value, casts it to a float, renders it to a string to the number of decimal places, and puts it back in as the value.
For WooCommerce 3+ (update): Since WooCommerce 3.0 checkout fields have changed a little bit so is not possible to reorder fields as before. There is a new ‘priority’ argument that handle fields order, for checkout fields and my account fields as well. Here is fully functional example for WooCommerce 3+: // REORDERING CHECKOUT BILLING FIELDS … Read more
It doesn’t grant you anything extra beyond being concise. If you prefer the more verbose syntax, then by all means, use that. One advantage to using auto props is that it can potentially save you from making a silly coding mistake such as accidentally assigning the wrong private variable to a property. Trust me, I’ve … Read more
For MongoDB 3.6 and newer: The $expr operator allows the use of aggregation expressions within the query language, thus you can leverage the use of $strLenCP operator to check the length of the string as follows: db.usercollection.find({ name: { $exists: true }, $expr: { $gt: [{ $strLenCP: ‘$name’ }, 40] } }) For MongoDB 3.4 … Read more
