Introduction to Creating Tables in Laravel
Many a time you will want to display your detailed structure of data in the form of a table to the application users. It may be organized either by score or by weight. There can be data of the type which needs to be displayed in a table format for the convenience of the users so that there is an order in the provided data as found necessary. There is something which is called as migrations in Laravel. It helps you to update and also alter your data in an organized and structured way. Tables are created manually with the help of SQL statements.
The document when it represents source code or data in both programming languages and markup languages, syntax helps to structure the document correctly with the help of the combination of symbols. The connections between symbols in syntax can be applied also to visual programming wherein there is a spatial layout and the symbols in the graphs are connected with the help of syntax. When there is a syntax error, the document is claimed to be syntactically invalid. Usually, the syntax is processed before the processing of semantics.
The three levels of Syntax are:
In the level of the Words which is also termed as the lexical level, evaluation of how characters are formed into a token is considered. In the level of the Phrases which in other words is called the grammar level, an estimate of how tokens are formed into phrases is understood. In the last level which is the Context level, there is the determination of the reference of the objects or variables used when the types are valid. These three levels are completely the part of Syntax.
Laravel itself is a framework that uses elegant syntax. Syntax helps you in many ways in Laravel. The syntax is a formal structure. It should not be misunderstood. The referencing of any variable with a particular sign is syntax. The function explodes which is commonly used in programming languages is not to be understood as Syntax. Laravel does not change the syntax of PHP of which it has a big collection in itself. There are regularly used PHP syntax which is there in Laravel. You can further extend it or instantiate it to avoid writing a lot of codes. That is the sole purpose of Syntax. Furthermore, Syntax helps you in many ways to put order and arrangement into the data that you want to be displayed to the users of your application. There is a syntax that is readily available according to the need of the document that needs to be edited and structured.
Steps to Create Laravel Table
We need to understand that a table may be created or generated in Laravel for various purposes. Whenever there is data that is necessary to be made available to the users in a structured and organized manner, the creation of a table comes into use which is much easier and convenient to use comparatively when you compare it with actual PHP coding. There is also a possibility of creating a real-time table with the help of Laravel wherein there is a shift of data in the table as per the necessary changes which are consistently made in progression. The best example can be that of the leader board in the gaming section.
Step 1: To create a table we need to use the create method which is available on the Schema facade. The schema has got many column methods of which you can use the desired format to define the column of the table in a plan. The hashtable and hashcolumn methods help you to check for existing tables. You can use the connection method to perform a schema operation if you find it necessary. There are a different set of codes and variables which are available to define and command the structuring of the table. You can use them as you want it.
Step 2: The rename method can be used for the purpose of renaming the table. The drop method helps to drop a particular table that exists in the database. If there are foreign key variables in your table then you need to make sure that you rename them so that Laravel does not assign any name based on its convention.
Step 3: You can update your columns and also update the entire table if required. Two arguments that are accepted by the table method are the table’s name and the closure which receives the blueprint data. There are a variety of column options coded and available in the schema builder.
Step 4: To modify the columns, there are many variable sets available in the schema builder. You can use them in rare situations when adding a modified column to your existing table. The nullable method can be used which belongs to the modifier base to null the data in the available columns. The addition of doctrine/dbal dependency to the composer.json file is absolutely necessary before any modification takes place.
Step 5: The change method which is available is used to make modifications to the attributes of the column which is existing in the database. If you want to increase or decrease the size range of a particular column, you can use this method which is readily available.
Step 6: The renamecolumn method can be used to rename the existing column if found necessary. The dropcolumn method can be used to rename the column and the addition of doctrine/dbal dependency to the composer.json file is necessary here too. Even multiple columns can be dropped along.
Step 7: Using the unique method you can create an index in the columns. You can create the index even after defining the column. Laravel is automated to define a name for the index but you can manually change it so that you can specify the name yourself. You can also rename and drop the index as per your need which is not a common thing though.
Example of Laravel Create Table
Examples of tables created using Laravel are the To-do app table wherein a to-do list is allowed to be created, leaderboard table which is there in the gaming arena when players are competing and the ranks are accordingly getting restructured constantly and there are many more such tables.
The given image is a sample of an contact details table wherein you can see the table structured in a manner where the contacts are in order and the format of the order number, names, email and action to view more data is kept together. Also, there are multiple pages to the given table data. You can formulate this table with the help of the above pointers which are used to create a table.
Creating a table with the help of Laravel is very easy and user friendly and there is a possibility of creating a table of your interest without too much coding which is otherwise necessary for normal table creation with the help of PHP. Laravel has provided convenient usage in its framework with the help of Syntax to make sure that tables are perfectly formulated.
