php - 如何划分数组的每个元素

问题描述

这是我的控制器 ，我需要划分由另一个表中的 max_rating 发布的每个评级，我该怎么做？我现在收到错误

遇到 PHP 错误 严重性：错误

消息：不支持的操作数类型

文件名：控制器/Performance.php

行号：74

我的模型

public function get_max_rating($kpiid){
    $this->db->select('max_rating');
    $this->db->where_in('id',$kpiid);
    $query = $this->db->get('kpi');
    return $query->row();
}

我的控制器：......

public function evaluate($r_id = 0) {
$this->form_validation->set_rules('rating[]', 'Rating', 'Trim|required');
if ($this->form_validation->run() == FALSE) {
$data = ['errors' => validation_errors()];
$this->session->set_flashdata($data);

$data['emp_review'] = $this->performance_model->get_emp_kpi($r_id);
$data['main_view'] = 'performance/evaluate_emp';
$this->load->view('layouts/main', $data);
} else {
$rating = $this->input->post('rating');
$comment = $this->input->post('comment');
$kpiid = $this->input->post('kpi_id');
$max_rating = $this->performance_model->get_max_rating($kpiid);
$decimal_rating = $rating / $max_rating->max_rating;
$reviewer = $this->session->userdata('user_id');

$ratingd = array();

for ($i = 0; $i < count($kpiid); $i++) {
    $ratingd[] = array(
        'rating' => $rating[$i],
        'comment' => $comment[$i],
        'decimal_rating' => $decimal_rating[$i],
        'kpi_id' => $kpiid[$i],
        'reviewer_id' => $reviewer,
        'review_id' => $r_id
    );
}
$this->performance_model->add_reviewer_rating($ratingd);


$data = [
    'final_comment' => $this->input->post('final_comment')
        ];

$this->performance_model->insert_final_comment($r_id, $data);
redirect('performance/display');
}

解决方案

您可以像这样计算循环 decimal_rating内部：for

    for ($i = 0; $i < count($kpiid); $i++) {
        $ratingd[] = array(
            'rating' => $rating[$i],
            'comment' => $comment[$i],
            'decimal_rating' => $rating[$i] / $max_rating->max_rating,
            'kpi_id' => $kpiid[$i],
            'reviewer_id' => $reviewer,
            'review_id' => $r_id
        );
