Avoiding the Not Secure Warning in Chrome

Chrome will have following impact after the version 65:

1. The websites that having Symantec-issued TLS certificates older than June 1, 2016 and that must be replaced
2. Chrome will mark non-secure pages containing password and credit card input fields as Not Secure in the URL bar.

To avoid this you need to install the SSL on the website that contains containing password and credit card input fields. 

For testing:

1. Please install the updated version of chrome - https://www.google.com/chrome/browser/canary.html
2. Configure Chrome to show the warning as it will appear in January 2017, open chrome://flags/#mark-non-secure-as and set the Mark non-secure origins as non-secure option to Display a verbose state when password or credit card fields are detected on an HTTP page. Then relaunch your browser.

WordPress - Briefly unavailable for scheduled maintenance. Check back in a minute.

Briefly unavailable for scheduled maintenance. Check back in a minute.

How to fix it.

When this happens, WordPress generates a .maintenance file in the root directory of the installation. With normal behavior, the update script completes and WordPress auto-removes the .maintenance file. In the case of an interruption of some sort, this file doesn’t get deleted and the message won’t go away.

The answer? Delete it manually.

Here are the steps:

• Log into your web server via FTP or your web host’s control panel.*
• Locate the root of your WordPress install (this is where you’ll find folders for wp-content, wp-admin, and wp-includes)
• Look for a file called .maintenance
• Delete it

wordpress - error "Sorry, you are not allowed to attach files to this post."

please edit the capabilities.php file at location /wp-includes/capabilities.php:

Upload Multiple Files Using FileUpload Control In ASP.NET 4.5 +

ASP.NET 4.5 and upper versions support this feature.

Now, FileUpload  control is built to support HTML 5, therefore it is only supported in browsers supporting HTML5. For other browsers it will work like a normal file upload control in ASP.NET.

A new Attribute introduces with the ASP.NET 4.5 FileUplaod control i.e. AllowMultiple, It takes either true or false.

In order to support multiple file uploads, set AllowMulitple="true" other than false.

<asp:FileUpload runat="server" ID="UploadImages" AllowMultiple="true" />

In addition to this control, some new properties have been included to support code-behind coding.


HasFilesCheck whether FileUpload control has multiple files or not.

PostedFilesBasically used to get all the files from the FileUpload control in the iteration.

Example code to upload files:

   <asp:FileUpload runat="server" ID="UploadImages" AllowMultiple="true" />  
   <asp:Button runat="server" ID="uploadedFile" Text="Upload" OnClick="uploadFile_Click" />  

protected void uploadFile_Click(object sender, EventArgs e) {  
    if (UploadImages.HasFiles) {  
        foreach(HttpPostedFile uploadedFile in UploadImages.PostedFiles) {  
            //code to save files  
        }  
    }  
}

Limit the number of cart Items in Woocommerce

There is 2 actions to check and to control if you want to limit cart items:

1. Add to basket - When product  is added to cart
2. Update Basket - When quantities are updated in cart page

Add a custom function hooked in woocommerce_add_to_cart_validation filter hook in function.php file of your active child theme (or theme), will allow customer to restrict the cart items to 'n' max and to display a custom message when this limit is exceeded:

1. Checking and validating when products are added to cart:
• Restrict Total Transaction Items:
  add_filter( 'woocommerce_add_to_cart_validation', 'only_n_items_allowed_add_to_cart', 10, 3 );
function only_n_items_allowed_add_to_cart( $passed, $product_id, $quantity ) {
$cart_items_count = WC()->cart->get_cart_contents_count();
$total_count = $cart_items_count + $quantity;

if( $cart_items_count >= n || $total_count > n ){
// Set to false
$passed = false;
// Display a message
wc_add_notice( __( "You can’t have more than n items in cart", "woocommerce" ), "error" );
}
return $passed;
}
• Restrict Item in a transaction:
  add_filter( 'woocommerce_add_to_cart_validation', 'only_five_items_allowed_add_to_cart', 10, 3 );
function only_five_items_allowed_add_to_cart( $passed, $product_id, $quantity ) {

//$cart_items_count = WC()->cart->get_cart_contents_count();

foreach ( WC()->cart->get_cart() as $cart_item ) {
if($cart_item['product_id'] == $product_id ){
$cart_items_count = $cart_item['quantity'];
break; // stop the loop if product is found
}
}

$total_count = $cart_items_count + $quantity;

if( $cart_items_count > 3 || $total_count > 3 ){
// Set to false
$passed = false;
// Display a message
wc_add_notice( __( "You can’t add more than 3 items in cart", "woocommerce" ), "error" );
}
return $passed;
}


2. Checking and validating when updating cart item quantities when products are added to cart

• Restrict Total Transaction Items:
  add_filter( 'woocommerce_update_cart_validation', 'only_six_items_allowed_cart_update', 10, 4 );
function only_six_items_allowed_cart_update( $passed, $cart_item_key, $values, $updated_quantity ) {

$cart_items_count = WC()->cart->get_cart_contents_count();
$original_quantity = $values['quantity'];
$total_count = $cart_items_count - $original_quantity + $updated_quantity;

if( $cart_items_count > 6 || $total_count > 6 ){
// Set to false
$passed = false;
// Display a message
wc_add_notice( __( "You can’t have more than 6 items in cart", "woocommerce" ), "error" );
}
return $passed;
}

• Restrict Item in a transaction:
  add_filter( 'woocommerce_update_cart_validation', 'only_five_items_allowed_cart_update', 10, 4 );
function only_five_items_allowed_cart_update( $passed, $cart_item_key, $values, $updated_quantity ) {

$cart_items_count = WC()->cart->get_cart_contents_count();
$original_quantity = $values['quantity'];
$total_count = $cart_items_count - $original_quantity + $updated_quantity;

if( $updated_quantity > 3 ){
// Set to false
$passed = false;
// Display a message
wc_add_notice( __( "You can’t have more than 3 items in cart", "woocommerce" ), "error" );
}
return $passed;
}


Wordpress - How to do a plugin/theme conflict test?

Sometimes when you find an issue on your wordpress site with Plugin, it will be caused by a plugin or theme conflict.
This can range from a simple CSS styling issue to a more complex issue where one Plugin/Theme is stopping another plugin/Theme from functioning properly.

do following Steps to a conflict test:

1. Deactivate all plugins and switch to default Twenty Fifteen theme (this will ensure site is as close to a clean install as possible).
2. Check the site to see if issue still exists. If issue goes away after deactivating other plugins and switching theme then this means that either the theme or one of the plugins was conflicting with another plugin. If the issue still exists then it is not a plugin or theme conflict.
3. If it turns out to be a plugin/theme conflict, then you need to activate the plugins/theme one by one until you find the plugin/theme that causes the issue to come back.
4. Once you have identified the conflict you can report the conflict to the developers of the plugin/theme and also to us.
