笨2.2.0 form_helper給人錯誤

Question

我試圖使用form_helper.php一個輔助類笨2.2.0 和下面是它給了錯誤，當我嘗試這樣做：

控制器文件

$this->load->helper('form'); 

視圖文件

<?php 
    $attributes = array('class' => 'form-horizontal', 'id' => 'admin-form'); 
    echo form_open($this, $attributes); 
?> 

錯誤：

A PHP Error was encountered

Severity: Warning

Message: strpos() expects parameter 1 to be string, object given

Filename: helpers/form_helper.php

Line Number: 53

A PHP Error was encountered

Severity: 4096

Message: Object of class CI_Loader could not be converted to string

Filename: helpers/form_helper.php

Line Number: 61

Although it does print the tag.

What I could be doing wrong here ?

Answer 1

您的代碼：

echo form_open($this, $attributes); 

是，正確的。它正確的：

echo form_open($YOUR_FORM_ACTION, $attributes); 

Reference

問題正在發生，因爲，你是路過$this，一個對象，而不是形式的行動（串）。

Answer 2

您不能使用$this作爲第一個參數，因爲它是內部CI對象。嘗試：

echo form_open('controller/method', $attributes);
