  • Laravel Livewire Dynamic Data Table: Efficiently obtain nested data of associated models
    Laravel Livewire Dynamic Data Table: Efficiently obtain nested data of associated models
    This article explores how to gracefully get nested data from an associated model from a string path when building a dynamic data table in LaravelLivewire. When dynamic access to deep attributes such as "user name" is required, direct object attribute access will be limited. By introducing Laravel's data_get() helper function and combining point-based path notation, this problem can be solved concisely and efficiently, while improving the readability and robustness of the code.

  • Laravel Eloquent: Implement conditional loading and filtering of associated data
    Laravel Eloquent: Implement conditional loading and filtering of associated data
    In relational databases, it is not supported to directly define "conditional foreign keys" to implement foreign key constraints based on specific values. However, at the application layer, we can flexibly implement conditional loading and filtering of associated data through query builders (such as LaravelEloquent), thereby achieving a "conditional connection" effect. This article will introduce in detail how to use the with method and its closure parameters in LaravelEloquent, conditional filtering of the association model, and how to use whereHas to filter the main model.

  • Manage the 'Select All/No Select All' checkbox functionality in a standalone container using jQuery
    Manage the 'Select All/No Select All' checkbox functionality in a standalone container using jQuery
    This article introduces in detail how to use jQuery to implement the "Select All/No Select All" function of multiple sets of check boxes to ensure that each set of check boxes is operated in an independent HTML container without affecting each other. By adding specific class names to the parent container and the "Select All" check box, combined with jQuery's event listening, DOM traversal and property operations, we can control the selected status of all check boxes in the same group when clicking "Select All" and reverse linkage, that is, when all check boxes in the same group are automatically selected, or when any check box is unchecked, "Select All" is automatically cancelled.

  • PHP realizes log monitoring and alarm monetization PHP system health monitoring solution
    PHP realizes log monitoring and alarm monetization PHP system health monitoring solution
    Selecting a log collection plan requires decision based on the project size and technology stack: small projects can use PHPMonolog to write file logs and push Filebeat; medium and large projects recommend ELK (strong functions but high resource consumption) or Loki Grafana (lightweight cloud native friendly) to achieve centralized monitoring; 2. Common challenges in building an alarm system include large log volume, false alarm missed, alarm fatigue and inconsistent format. The response strategies are log hierarchical filtering sampling, refined threshold and aggregate alarms, hierarchical notification rotating mechanism, unified JSON log specification; 3. In addition to error logs, PHP health monitoring should also pay attention to request response time, CPU/memory/disk/network usage, database connections/slow query/QPS, cache hit rate, P
