A form to the site front end allows users to submit information that can be saved to the database or sent to emails. For example, front-end forms in Joomla are used to create article (com_content), contact form (com_contact), user registration form (com_users).
With the help of class JForm, you can easily create HTML forms in Joomla. Forms created using JForm consist of form fields, implemented as JFormFields. There is a JFormField for each different field type you can find in a form, such as a text field type and a date field type. There are many standard field types.
When you create a menu for any view of component, there are many options in the menu you can configure. These values can easily be accessed in Joomla code.
The Joomla framework allows the use of parameters stored in each component. The fields for the configuration options are stored in the XML file located at admin/config.xml.
In the back-end, administrators can select an image to be associated with each item. You can also display details of the image on the administrator's list of items. In the front-end, display the image associated with the item and also allow a user to upload an image when creating a new item.
Modals are the pop-up-like windows which appear in several places within Joomla. For example, when as an administrator you create a new menu item, and select a Menu Item Type of Single Article, then when you click to select the article, a pop-up appears displaying the details of the articles available and allowing you to select one.
JHtml is utility class for all HTML drawing classes. The _ method of JHtml is a static function that grants quick access to a number of other static methods. The return value of this function depends on the return value of the method resolved by parsing the first parameter.
Joomla allow the administrator to define ordering of items by clicking on the ordering symbol (a little up arrowhead above a down arrowhead) at the top left of the items table, and then clicking on one of the three vertical dots symbols and sliding the record up or down to reorder.
Component is a type of Joomla extension (like Modules and Plugins). Unlike modules and plugins, components have two main parts - site and administrator. The site part is visible to visitors (front-end access). The administrator part is interface for managing extension from the back-end.
The real power of custom fields is that you can use it in your own overrides. You can use the data or information stored in the custom fields the way you want. You have all the custom fields corresponding to the current item accessible through a property in $this->item variable called jcfields.
You can take over control of virtually all the output that is generated by Joomla. Except for files that are provided in the Joomla! distribution itself, overrides or customization eliminate the need to hack core files that could change when the site is updated to a new version.
