Question

我在控制器功能和调用表中创建表格，以便在视图页面中显示。

我在视图页面中的代码

<?php 
    foreach($tables as $table){
        echo $tables;
    }
?>

这是我的控制器

$table ='';
    $tables[]= array();
    $result = array();
    $param = new stdClass();

    if(sizeof($_GET) > 0){
        $param->date_from = $this->input->get('date_from');
        $param->date_to = $this->input->get('date_to');
        $param->sales_name = $this->input->get('sales_name');
        $data['result'] = $this->m_commission->check_invoice_user ($param);
        foreach ($result as $result){
        $table = '<div>'.$result->INVOICEDATE.'</div>';
        }
        $tables[] = $table;
    }
    $data['tables'] = $tables;
    $data['team'] = $this->m_user->get_team();
    $this->load->view('v_header');
    $this->load->view('v_test', $data);
    $this->load->view('v_footer');

我的模型我已经检查查询已经有效了。

第一眼（回声$table而非$tables）：

<?php 
    foreach($tables as $table){
        echo $table;
    }
?>

（编辑:) 在您的控制器中：

    $tables[]= array();
    $param = new stdClass();

    if(sizeof($_GET) > 0){
        $param->date_from = $this->input->get('date_from');
        $param->date_to = $this->input->get('date_to');
        $param->sales_name = $this->input->get('sales_name');
        $results = $this->m_commission->check_invoice_user ($param);
        foreach ($results as $result){
           $tables[]= '<div>'.$result->INVOICEDATE.'</div>';
        }
    }
    $data['tables'] = $tables;
    $data['team'] = $this->m_user->get_team();
    $this->load->view('v_header');
    $this->load->view('v_test', $data);
    $this->load->view('v_footer');

在您的模型中，更改行：

if ($query->num_rows() > 0) {
            $result = $query->num_rows();
        }
        return $result;

到

if ($query->num_rows() > 0) {
     return $query->result();
}else return false;

Answer 2

它仍然显示错误“数组到字符串转换”并显示“为foreach（）提供的无效参数”

这是我的模特

function check_invoice_user($param){
    $result = array();
    $this->db->select("*");
    $this->db->from("bsm_salesinvoiceheader bh");
    $this->db->join("bsm_customerpayment bsmc", "bsmc.INVOICENUMBER = bh.INVOICENUMBER", 'LEFT');
    $this->db->join("bsm_salesinvoicelines bsms", "bsms.INVOICENUMBER = bh.INVOICENUMBER", 'LEFT');
    $this->db->like("bh.ADDITIONALFIELD_2", $param->sales_name, 'BOTH');
    $this->db->or_like("bh.ADDITIONALFIELD_5", $param->sales_name, 'BOTH');
    $this->db->or_like("bh.ADDITIONALFIELD_8", $param->sales_name, 'BOTH');
    $this->db->where("bh.INVOICEDATE >= ",$param->date_from);
    $this->db->where("bh.INVOICEDATE <= ",$param->date_to);
    $this->db->where("bsmc.APPLIEDDATE >= ",$param->date_from);
    $this->db->where("bsmc.APPLIEDDATE <= ",$param->date_to);
    $this->db->order_by("bh.INVOICEDATE", 'ASC');

    $query = $this->db->get();
    echo $this->db->last_query();
    if ($query->num_rows() > 0) {
        $result = $query->num_rows();
    }
    return $result;

}

Answer 3

查看：

<?php 
    foreach($tables as $table){
        echo $table;
    }
?>

实际上它仍然是一个数组。试试这个：

<?php 
print_r($tables);
    foreach($tables as $table){
        echo $table['your_column_name'];
        //print_r($table);
    }
?>
