  • "Copying" a widget with slight code changes

    Posted 11 years 9 months ago
    • Hello Again,

      This time im calling for your help in this situation, i want to create a copy of a widget, so in one i have one widget coded text, and in the other i have a different coded text, the widget is a popup login, what i did here was editing the loginform.php and creating a loginform2.php what happens though is when i go to the widgets section in gantry, the page formatting is completely gone, everything is out of place and i cant add or remove widgets until i delete loginform2.php

      my question is, the widget is composed by:

      loginform.php
      <?php

     }
}

      and i edited:
      templateDetails
      template.less

      basically i did everything like explained in the login widget tutorial by gantry

      what i did to try my solution was creating a second loginform.php changing every widget name and every reference that cant exist in double and then i did the changes in the code that i wanted.

      What am i doing wrong? did i change something i shouldnt have? do i have to create another version of every file to have the existence of 2 separate widgets that do the same but with some differences?

      thanks in advance

    • Hi,
      the problem is that when you copy the widget's files and declare a new widget, PHP throws "class already exists" errors and thus messes up the admin page. After copying files you need to rename all class names and fix their references.
      Mind me asking, why a new copy of the login form widget? You can instead add an option to the loginform.xml file and edit the loginform.php file to modify the widget's behavior based on that option.

    • Hello, thanks for the response,

      to be really honest, copying the widget is only because i dont really know that much about php, im just entering this world, so, copying the widget was the only thing i could think about, can you help me with changing the .xml so i can edit every aspect of the login form? what i need is a way to alter the "register","forgot password","remember me","username" and "password" link's text in the widget customization form, instead of changing it directly in the code, that would be absolutely awesome, as i am also thinking of expanding to new languages and it would be perfect for that case...

      Thanks in advance,

    • Hi,
      Gantry makes adding new fields to widgets very easy. All you need to do is to modify the widget's .xml file and add a new field:
      <field name="my_field_name" type="text" label="My Custom Field" default="" class="widefat" readonly="false" />
      You must give the field a unique name (it's "my_field_name" here). So now if you go to the Widgets manager you see that the widget has this new "My Custom Field" option. Now to display that value in the widget output you need to modify the widget's .php file and add:
      <?php echo $instance['my_field_name']; ?>
      where you want that text to appear. And done.
