How to develop the filtering and search functions of the accounting system through PHP

Abstract: This article will introduce how to develop the filtering and search functions of the accounting system through PHP. We will provide an implementation guide, including specific code examples, to help developers understand how to use PHP language to implement the functions of filtering and searching accounting data.

Introduction: With the popularity of mobile Internet, people are becoming more and more accustomed to using accounting systems to manage personal finances. In many accounting systems, filtering and search functions are very important because they can help users quickly find the required accounting data and filter and classify the data. PHP-based developers can learn how to use PHP to develop the filtering and search functions of the accounting system through this article.

1. Implementation of filtering function

1.1 Create filter form

First, we need to create a filter form in the web page. This form contains several fields that specify the criteria for accounting data to be filtered. For example, we can use the drop-down menu to select the accounting type, use the input box to specify the amount range, use the date picker to select the date, etc.

Sample code:

<form action="filter.php" method="GET">
    <label for="type">记账类型：</label>
    <select name="type" id="type">
        <option value="">全部</option>
        <option value="收入">收入</option>
        <option value="支出">支出</option>
    </select>
    <br>
    <label for="amount">金额范围：</label>
    <input type="number" name="min" id="min" placeholder="最小金额">
    <input type="number" name="max" id="max" placeholder="最大金额">
    <br>
    <label for="date">记账日期：</label>
    <input type="date" name="date" id="date">
    <br>
    <input type="submit" value="过滤">
</form>

1.2 Processing filtering requests

In the filter.php file, we need to obtain the data submitted by the filter form and query the records in the database according to the conditions account data. Then, the query results are displayed on the web page.

Sample code:

<?php
    // 获取过滤条件
    $type = $_GET['type'];
    $min = $_GET['min'];
    $max = $_GET['max'];
    $date = $_GET['date'];
    
    // 构建查询语句
    $sql = "SELECT * FROM accounting WHERE 1 = 1";
    if ($type != '') {
        $sql .= " AND type = '$type'";
    }
    if ($min != '') {
        $sql .= " AND amount >= '$min'";
    }
    if ($max != '') {
        $sql .= " AND amount <= '$max'";
    }
    if ($date != '') {
        $sql .= " AND date = '$date'";
    }
    
    // 执行查询，并显示结果
    // ...
?>

The above code will construct a query statement based on the obtained filter conditions, and obtain qualified accounting data from the database by executing the query statement. Developers can use relevant functions of database operations to perform query operations based on specific circumstances, and display the results on the web page.

2. Implementation of search function

2.1 Create search form

In addition to the filtering function, the accounting system also needs to provide a search function so that users can search for relevant information based on keywords Accounting data. To do this, we need to create a search form in the web page. This form contains an input box for entering keywords, and a submit button.

Sample code:

<form action="search.php" method="GET">
    <label for="keyword">关键字：</label>
    <input type="text" name="keyword" id="keyword" placeholder="请输入关键字">
    <input type="submit" value="搜索">
</form>

2.2 Processing search requests

In the search.php file, we need to obtain the keywords submitted by the search form and query the database based on the keywords accounting data. Then, the query results are displayed on the web page.

Sample code:

<?php
    // 获取关键字
    $keyword = $_GET['keyword'];
    
    // 构建查询语句
    $sql = "SELECT * FROM accounting WHERE description LIKE '%$keyword%'";
    
    // 执行查询，并显示结果
    // ...
?>

The above code will construct a query statement based on the obtained keywords, and obtain qualified accounting data from the database by executing the query statement. Developers can use relevant functions of database operations to perform query operations based on specific circumstances, and display the results on the web page.

Conclusion: Through the implementation guide and specific code examples of this article, developers can learn how to use PHP to develop the filtering and search functions of the accounting system. Through these functions, users can more easily filter and find the required accounting data, improving the efficiency of the accounting system. I hope this article can be helpful to developers in PHP development.
