Question

这是我在view / company / companyview.php下的查看页面我对PHP＆amp;笨

我写了下面的代码并执行。没有结果，也没有更新。我哪里错了？。

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<head>
<title>Welcome to Home page</title>
<link rel="stylesheet" type="text/css" href="<?php echo base_url();?>/css/topmenu.css">
</head>
<body>
<div class="container">
<br>
<p></p>
<div class="left">
<?php $this->load->view('company/sidemenu.php');?>
</div>
<div class="content">
<!-- <table border="1" cellpadding="3" cellspacing="0" bgcolor="white" id="table_style"> -->
<table id="table_style" border="1" cellpadding="3" cellspacing="0">
  <tr>
    <th>ID</th>
    <th>code</th>
    <th>name</th>    
    <th>address</th>    
    <th>tel</th>    
    <th>fax</th>
    <th>email</th>
  </tr>
<?php
$this->load->library('table');

foreach ($query as $row) 
{
    echo "<tr>";
    echo "<td>" . $row->id . "</td>";
    echo "<td>" . $row->code . "</td>";
    echo "<td>" . $row->name . "</td>";
    echo "<td>" . $row->address . "</td>";
    echo "<td>" . $row->tel . "</td>";
    echo "<td>" . $row->fax . "</td>";
    echo "<td>" . $row->email . "</td>";
    echo "<td>" . anchor('company/inputco/' . $row->id, 'Edit') . "</td>";
    echo "<td>" . anchor('company/del/' . $row->id, 'Delete') . "</td>";  // delete function OK
    //echo anchor('books/input/'. $row->id,'Edit');
    echo "</tr>";
}
?>
</table>
</div>
</div>


</body>
</html>

然后它会调用

是CI_Controller

function inputco($id)
{
        $this->load->helper('form');
        $this->load->library('table');
        $this->load->helper('html');
        $this->load->view('menu_top.php');
        $this->load->model('company_model');

        $query = $this->company_model->get($id);


        $data['id']['value'] = $query['id'];
        $data['code']['value'] = $query['code'];
        $data['name']['value'] = $query['name'];
        $data['address']['value'] = $query['address'];
        $data['tel']['value'] = $query['tel'];
        $data['fax']['value'] = $query['fax'];
        $data['email']['value'] = $query['email'];
        $data['business']['value'] = $query['business'];
        $data['url']['value'] = $query['url'];
        $data['rocno']['value'] = $query['rocno'];

        $this->load->view('company/companyinput', $data);
}

视图/公司/ companyinput.php

Answer 1

我不是100％确定你的问题，

但是在这样的view/company/companyinput.php行：

<input size="10"<?php echo form_input($id);?>

不正确。

您可以阅读更多here，但您的代码实际上会输出类似

的内容

  <input size="10"<input type="text" name="1" value=""  />

要输出带有大小的文本框，您应该使用类似这样的内容

<?php echo form_input(array( 'name' => $id, 'size' => '10'));?>

//编辑实际上仔细检查你的错误是你将$id传递给form_input（）方法。当视图中$ id的值实际上是一个包含奇怪值的数组时。

我认为您的问题出在Controller中，我无法在您的模型中看到，但我想它会返回一个这样的数组{'id'=>1, 'code'=>'ABC123','name'=>'Toms Hardware' ... }

但是当你这样做时：

$data['id']['value'] = $query['id'];

它写入存储在数组$ data ['id']中的'value'索引，该索引不是数组..它是一个数字或字符串或其他东西。我建议您查看HTML表单的来源，我认为它在输入框中有一些字符串查找名称。

我认为你真的想要这样的东西：

<?php echo form_input(array( 'name' => '', 'value'=> $id, 'size' => '10'));?>

如何使用指定的id（代码点火器）将数据更新到数据库

是CI_Controller

视图/公司/ companyinput.php
