现在print_r（$ puja_samagri）;死; //添加并查看它只是一个记录

所以在foreach中使用数组instaed ，即= $ puja_samagri []

<?php 
$samgri = $this->crud_model->get_puja_samagri_by_puja_order($param1,$param);

foreach ($samgri as $row){

$puja_samagri = $row['puja_samagri'];

}

注意：在其他foreach中执行相同的操作只需定义数组，否则它只包含最后一个值...

Answer 2

请先打印$samgri变量并查看获得的结果。如果您的$samgri包含结果数组，请使用以下代码更改您的代码。

<?php 
        $samgri = $this->crud_model->get_puja_samagri_by_puja_order($param1,$param);
        $puja_samagri = [];
        foreach ($samgri as $row){

        $puja_samagri[] = $row['puja_samagri'];

        }    
        if(!empty($puja_samagri))
        {
            foreach ($puja_samagri as $samagri_id){

            $samg = $this->crud_model->get_puja_samagri_by_id($samagri_id);
            }

            foreach ($samg as $row){
        }

    ?>

Answer 3

您应该获取数组，如Codeigniter User Guide

中所述

$query = $this->db->query("YOUR QUERY");

 foreach ($query->result_array() as $row)
{
 echo $row['title'];
 echo $row['name'];
 echo $row['body'];
}

获取的只有一条记录并非全部为什么？
