显示组件视图，并显示500内部服务器错误 [英] Component View displaying with 500 Internal Server Error

问题描述

在Joomla组件开发教程之后，我遇到了问题.我遵循的与该问题有关的教程是此和此.

I have having issues following the tutorial of component development of Joomla. The tutorials I followed related to the issue are this and this.

我可以正确查看默认视图，但是当我单击new或edit和delete按钮时，或者当我也浏览../administrator/index.php?option=com_testimonials&view=testimonial&layout=edit时，都会出现该错误.

I can view the default view properly, but when I click the new or edit and delete button, or when I browse too ../administrator/index.php?option=com_testimonials&view=testimonial&layout=edit I get that error.

我已经多次检查了代码，但是我找不到错误的地方.

I have rechecked the code so many times but I just can't find where I went wrong.

文件:controllers \ testimonial.php

File: controllers\testimonial.php

class TestimonialsControllerTestimonial extends JControllerForm
{
    //Nothing yet as per the tutorial
}

文件:models \ testimonial.php

File: models\testimonial.php

class TestimonialsModelTestimonial extends JModelAdmin {
    public function getTable($type = 'Testimonials', $prefix = 'TestimonialsTable', $config = array()) {
        return JTable::getInstance($type, $prefix, $config);
    }

    public function getForm($data = array(), $loadData = true) {
        // Get the form
        $form = $this -> loadForm('com_testimonials.testimonial', 'testimonial', array('control' => 'jform', 'load_data' => $loadData));
        if(empty($form)) {
            return false;
        }
        return $form;
    }

    protected function loadFormData() {
        // Check the session for previously entered form data
        $data = JFactory::getApplication() -> getUserState('com_testimonials.edit.testimonial.data', array());
        if(empty($data)) {
            $data = $this -> getItem();

    }

推荐答案

问题出在您的视图文件夹名称中.根据您指定的view = testimonial更改testimonials folder name to testimonial.

The problem is in your view folder name. Change testimonials folder name to testimonial as you have specified view=testimonial.

让我知道它是否不起作用.

let me know if it does not work.

更新: 如前所述，您的表格存在命名问题-

Update: As discussed your table having naming problem-

class TestimonialsTableTestimonial extends JTable 
{ 
public function __construct(&$db) { 
parent::__construct('#__testimonial_table', 'id', $db); 
} 

function bind($array, $ignore = '') 
{ 

return parent::bind($array, $ignore); 
} 

}
