Laravel Validation size value Example

Laravel ·

Teams applying “Laravel Validation size value Example” in a production project can use the official article to record implementation, review and debugging time, then compare that effort with tests and shipped functionality instead of treating activity as performance by itself.

Before copying the example into a live application, confirm version-specific behaviour with the official Laravel website and test it against the project’s actual database and runtime.

Hi Guys,

Today, I will learn you to create validation size in laravel.we will show example of laravel validation size.

The field under validation must have a size matching the given value. For string data, value corresponds to the number of characters. For numeric data, value corresponds to a given integer value (the attribute must also have the numeric or integer rule). For an array, size corresponds to the count of the array. For files, size corresponds to the file size in kilobytes..you can easyliy use size validation in laravel.

Here, I will give you full example for simply size validation in laravel bellow.

solution


// Validate that a string is exactly 12 characters long...
'tag' => 'size:12';
// Validate that a provided integer equals 10...
'number' => 'integer|size:10';
// Validate that an array has exactly 5 elements...
'list' => 'array|size:5';
// Validate that an uploaded file is exactly 512 kilobytes...
'gif' => 'file|size:512';
