Angular/Ionic not updating an image src when ng-src is empty

The Angular ngSrc directive serves to properly set an image src via Angular. As anything in Angular, it updates the image as soon as the contained Angular expression changes. However, when the ng-src attribute is empty, Angular will not empty the src attribute. To overcome this, use the trick below.

<img ng-src="{{ element.image || '//:0' }}" />

Background

The ngSrc directive explicitly returns when the attribute value is false. As a workaround, set a "blank" image src when the image is empty. As somebody on Stackoverflow writes, //:0 serves this purpose: It adopts the current protocol, omits the hostname and sets the port to zero, which is invalid and should be killed by the network layer.

As a result, Angular should now correctly empty the src attribute when ng-src empties.

Self Signed SSL Certificates in PhoneGap

Code to allow self signed certs on PhoneGap 

Android:

• If you are doing development: android:debuggable="true" in the manifest, you should allow the browser to request data from servers with a self-signed or bad SSL cert 
• If you are releasing an application, you should remove the android:debuggable="true" (Android Market won't let you release with this on anyway) and you will NOT be able to send data to a server with a bad SSL cert 
• If you don't have this flag set, the default will be what the default is now, which is that you won't be able to send data to servers with a self-signed cert 

iOS: 

Just Add below code at the end of you AppDelegate.m file

@implementation NSURLRequest(DataController)
+ (BOOL)allowsAnyHTTPSCertificateForHost:(NSString *)host
{
    return YES; 
}
@end

Error: Database location or iosDatabaseLocation value is now mandatory in openDatabase call

if you are using Cordova sqlite plugin you may have this issue while open local DB file.

 _sqlLiteDB = $cordovaSQLite.openDB({ name: "testDB.db", iosDatabaseLocation:'default'}); 
// Works on android but not in iOS

                   

Error: Database location or iosDatabaseLocation value is now mandatory in openDatabase call

Use below to open DB:
window.sqlitePlugin.openDatabase({ name: "testDB.db", location: 2, createFromLocation: 1});

Solution:

if(isAndroid){
                    // Works on android but not in iOS

                    _sqlLiteDB = $cordovaSQLite.openDB({ name: "testDB.db", iosDatabaseLocation:'default'}); 

} else{
                    // Works on iOS 

                    _sqlLiteDB = window.sqlitePlugin.openDatabase({ name: "testDB.db", location: 2, createFromLocation: 1}); 

 }

error JSON.stringify()ing argument: RangeError: Invalid Date

There is minor bug in contact plugin in cordova ionic. contact list is loaded with error due to the birthdate field in contact card. Its bad practice to keep minor error in execution of code, It may effect to different OS versions.

error JSON.stringify()ing argument: RangeError: Invalid Date

Cordova Plugin: cordova-plugin-contacts
Verison: 2.1.0 "Contacts"

Open convertUtils.js file  

File Path: plugins/cordova-plugin-contacts/www/convertUtils.js

Find function "toCordovaFormat" and remove below try-catch code.

 try {
         contact.birthday = new Date(parseFloat(value));
} catch (exception){
          console.log("Cordova Contact toCordovaFormat error: exception creating date.");
}

add below code instead of try-catch

if (value !== null) {

        try {

                contact.birthday = new Date(parseFloat(value));

               

                //we might get 'Invalid Date' which does not throw an error

                //and is an instance of Date.

                if (isNaN(contact.birthday.getTime())) {

                       contact.birthday = null;

               }

               

        } catch (exception){

                console.log("Cordova Contact toCordovaFormat error: exception creating date.");

        }

}

Check below screenshot for better understand.

iOS contact card does not have value for "displayName". "displayName" is used for the android devices. So For iOS device, use "name.formatted" instead of "displayName".

Cheers.... Keep Coding... :)

Woocommerce issue when products and categories has same base path

404 on Product detail page?

Ran into this issue where I needed a url structure such as/shop/<category> and /shop/<category>/<product>/.

/shop/<category>/ works fine but once you click a product you get a nice looking 404 page.

My settings:
Product category base - /shop
Product permalink base -> Custom Structure - /shop/%product_cat%

The Fix:

Set the ‘Product category base’ to shop and the custom product base to /shop/%product_cat%.
Then in your functions.php file add this little snippet:

$user_id = $order->user_id;
