在这里，我需要使用codeigniter将数据插入mysql数据库。但数据未插入数据库，也未显示任何错误。以下是模态，控制器和视图页面的代码。在database.php文件中，一切正常。在这里，如何调试代码以及错误是什么。提前致谢。
答案 0 :(得分：0)
您从不向控制器发布任何内容。看看你的视图文件的这一行。
import React, { Component } from "react";
import ExpenseItem from "./ExpenseItem.js";
class ExpensesList extends Component {
state = {
expenses: [{ id: '12345', name: 'Pizza', cost: '20' }],
cost: "",
name: ""
};
handleChange = (event, name) => {
this.setState({ [name]: event.target.value });
};
handleSubmit = (event) => {
event.preventDefault();
let newExpense = {
id: Math.random(),
name: this.state.name,
cost: this.state.cost
}
this.setState(prevState => ({
expenses: [...prevState.expenses, newExpense], // add new expense to expenses array
cost: "", // reset this field
name: "" // reset this field
}));
}
render() {
return (
<div>
<ul className="list-group">
{this.state.expenses.map((expense) => (
<ExpenseItem
id={expense.id}
name={expense.name}
cost={expense.cost}
/>
))}
</ul>
<div className="row mt-3">
<h2> Add Expenses </h2>
<form onSubmit={this.handleSubmit}>
<div className="row">
<div className="form-group">
<label for="name">Name</label>
<input
required="required"
type="text"
className="form-control"
id="name"
value={this.state.name}
onChange={e => this.handleChange("name")}
></input>
</div>
<div className="form-group">
<label for="name">Cost</label>
<input
required="required"

export default ExpensesList;
更改为：
