我有一个简单的 HTML 表单,使用 json_encode 将 PHP 变量(通过 value=)发送到文件,然后使用 json_decode 提取和回显结果。我正在努力获得正确的语法或方法来解码 Opencart 所需的对象环境中的 json_decode。当我使用下面的程序方法时,它工作正常。
我尝试了各种语法更改,但它们返回错误,因此我认为语法不正确,或者我的方法无法通过这种方式完成。第一个代码是返回正确结果的程序方法。第二个代码是失败的 OOP 方法。- (假设语法错误。
Code Working:-
<form id="myForm" action="radio_result.php" method="post"
enctype="multipart/form-data">
<input type="radio" name="service" value="<?php echo
htmlentities(json_encode($service_onx));?>"> ONX
//additional code excluded.
radio_result.php // not all code shown
<?php
if(!empty($_POST['service'])) {
$service = json_decode($_POST['service'], true);
print_r($service);
Code failing:-
<form id="myForm" action="index.php?route=checkout/checkout"
method="post" enctype="multipart/form-data">
<input type="radio" name="service" value="<?php echo
htmlentities(json_encode($service_onx));?>"> ONX
checkout.php // not all code shown
$this->session->data['service'] = (isset($this->request-
>post(json_decode(['service'])))) ? $this->request->post['service'] :
"not_set";
$data['onx'] = $this->session->data['service'][0];
$data['eta'] = $this->session->data['service'][1];
Error result:-
Fatal error: Cannot use isset() on the result of an expression (you can
use "null !== expression" instead) in
C:\wamp64\www\catalog\controller\checkout\checkout.php on line 101
I would like to get the json_decode working in the Opencart framework
checkout.php so that I can use the reult further.
