php - 我该如何解决 "Object of class CI_Table could not be converted to string"？

Question

我是 CI 的新手，我按照网站上的教程进行操作，然后遇到了这个错误。这是我的 View 代码:

$data = array('table_open' => '<table class = "table-bordered">');

echo $this->table->set_template($data);

$col1 = array('data' => 'No');
$col2 = array('class' => 'col-md-4', 'data' => 'Agenda');
$col3 = array('class' => 'col-md-2', 'data' => 'Category');
$col4 = array('class' => 'col-md-2', 'data' => 'Date');
$option = array('class' => 'col-md-4', 'data' => 'Option');

echo $this->table->set_heading($col1, $col2, $col3, $col4, $option);
// echo $this->table->set_heading('No', 'Agenda', 'Category', 'Date', 'Option');
$no = 1;
if($agenda > 0) {
    foreach($agenda as $ag) {

        $item = $this->table->add_row($no++, $ag->agenda, $ag->agenda_cat, $ag->due_date,
                anchor('agenda/edit' . $ag->id_agenda, 'Edit', array('class' => 'btn btn-info col-md-offset-1')) . " " .
                anchor('agenda/delete' . $ag->id_agenda, 'Delete', array('class' => 'btn btn-danger'))
            );
    }
    echo $item;
}

echo $this->table->generate();

table->set_heading() 和 table->add_rows() 总是出错。

对于代码 echo $this->table->set_template($data);，它总是给出“1”作为输出。有人可以帮忙吗？

Answer 1

在 Controller 中加载库

$this->load->library('table');

或Config/autoload.php

$autoload['libraries'] = array('table');

set_heading 函数总是返回对象。所以不使用 echo

所以你的代码(删除echo)

<?php
    $data = array(
        'table_open' => '<table class="table-bordered">');

     $this->table->set_template($data);

    $col1 = array('data' => 'No');
    $col2 = array('class' => 'col-md-4', 'data' => 'Agenda');
    $col3 = array('class' => 'col-md-2', 'data' => 'Category');
    $col4 = array('class' => 'col-md-2', 'data' => 'Date');
    $option = array('class' => 'col-md-4', 'data' => 'Option');

    $this->table->set_heading($col1, $col2, $col3, $col4, $option);
    // echo $this->table->set_heading('No', 'Agenda', 'Category', 'Date', 'Option');
    $no = 0;

    if(empty($agenda))
    {
        foreach($agenda as $ag)
        {
            $this->table->add_row($no++, $ag['agenda'], $ag['agenda_cat'], $ag['due_date'],
                anchor('agenda/edit' . $ag['id_agenda'], 'Edit', array('class' => 'btn btn-info col-md-offset-1')) . " " .
                anchor('agenda/delete' . $ag['id_agenda'], 'Delete', array('class' => 'btn btn-danger')));
        }
    }
    else
    {

    }
