我正在尝试制作一个没有任何库或框架的PHP模板,以便了解模板。该模板为<select>
,显示所有国家/地区的列表。它在我模板化之前完全正常工作,所以问题不在于<select>
元素逻辑。
但是,选择模板不会渲染到页面。
这是我的代码:
country_select.php:
<?php
class CountrySelect {
static $template = 'country_select_template.php';
public static function display() {
if ( class_exists( 'View' ) ) {
// Get the full path to the template file.
$templatePath = dirname( __FILE__ ) . static::$template;
// Return the rendered HTML
return View::render( $templatePath );
}
else {
return "You are trying to render a template, but we can't find the View Class";
}
}
}
?>
country_select_template.php:
<div class="form-group col-sm-6">
<div class="select">
<span class="arr"></span>
<select data-bind="options: _countries,
optionsText: 'name',
optionsValue: 'geonameId',
value: selectedCountry,
optionsCaption: 'Country'">
</select>
</div>
</div>
view.php:
<?php
/** View.php **/
class View {
/**
* -------------------------------------
* Render a Template.
* -------------------------------------
*
* @param $filePath - include path to the template.
* @param null $viewData - any data to be used within the template.
* @return string -
*
*/
public static function render( $filePath, $viewData = null ) {
// Was any data sent through?
( $viewData ) ? extract( $viewData ) : null;
ob_start();
include ( $filePath );
$template = ob_get_contents();
ob_end_clean();
return $template;
}
}
?>
view_renderer.php:
<?php
require('view.php');
?>
以下是我尝试渲染模板的php页面中的相关代码。请注意,“region_select”尚未模板化,这就是我的“country_select用来查看的方式。”
<div class="row">
<?php
require 'scripts/back_end/views/country_select.php';
require 'scripts/back_end/views/view.php';
View::render('country_select_template.php');
?>
<div class="form-group col-sm-6">
<div class="select">
<span class="arr"></span>
<select data-bind="options: _regions,
optionsText: 'name',
optionsValue: 'name',
value: selectedCity,
optionsCaption: 'Region'">
</select>
</div>
</div>
如何获取country_select_template中的html以呈现到页面?应该启动模板以呈现给页面的调用代码是
<?php
require 'scripts/back_end/views/country_select.php';
require 'scripts/back_end/views/view.php';
View::render('country_select_template.php');
?>
我已将调用代码更改为:
<?php
require 'scripts/back_end/views/country_select.php';
require 'scripts/back_end/views/view.php';
echo View::render('country_select_template.php');
?>
我看到我在php错误日志中有这个错误:
[2016年2月15日09:33:35欧洲/柏林] PHP警告: require(scripts / back_end / views / country_select.php):无法打开 stream:没有这样的文件或目录 第92行/Applications/MAMP/htdocs/its_vegan/index.php [2016年2月15日] 09:33:35欧洲/柏林] PHP致命错误:require():打开失败 必需的'scripts / back_end / views / country_select.php' (include_path ='。:/ Applications / MAMP / bin / php / php7.0.0 / lib / php')in 第92行/Applications/MAMP/htdocs/its_vegan/index.php
答案 0 :(得分:3)
View :: render返回代码。它不会打印出来。
所以我认为应该这样做:
<?php
require 'scripts/back_end/views/country_select.php';
require 'scripts/back_end/views/view.php';
echo View::render('country_select_template.php');
?>
