使用 curl 提交/检索表单结果

问题描述：

我在尝试使用 curl 将数据发布到页面并在提交表单后检索结果时需要帮助.

I need help in trying to use curl to post data to a page and retrieve the results after the form has been submitted.

我创建了一个简单的表单:

I created a simple form:

<form name="test" method="post" action="form.php">              
    <input type="text" name="name" size="40" />
    <input type="text" name="comment" size="40" />
    <input type="submit" value="submit" />
</form>

此外，我有 php 代码可以在同一页面中处理此表单.它所做的只是回显表单值.

In addition, I have php code to handle this form in the same page. All it does is echo back the form values.

我一直使用的 curl 是这样的:

The curl that I have been using is this:

  $h = curl_init();

  curl_setopt($h, CURLOPT_URL, "path/to/form.php"); 
  curl_setopt($h, CURLOPT_POST, true);
  curl_setopt($h, CURLOPT_POSTFIELDS, array(
  'name' => 'yes',
  'comment' => 'no'
  ));
  curl_setopt($h, CURLOPT_HEADER, false);
  curl_setopt($h, CURLOPT_RETURNTRANSFER, 1);

  $result = curl_exec($h);
  echo $result;

当我启动包含 curl 代码的页面时，我得到了 form.php 页面内容，但它没有显示提交表单时 PHP 应该回显的变量.

When I launch the page with the curl code in it, I get the form.php page contents but it doesn't not show the variables that PHP should have echo'd when the form is submitted.

非常感谢您的帮助.

谢谢.

答

AHHHH 看了你的评论，问题就清楚了.

AHHHH after your comment, the problem is clear.

您需要在数组中再包含一个 POST 变量.

you need to include one more POST variable in your array.

'submitted' => 'submitted'

如果单击提交按钮也会返回一个 post 值，您正在处理 PHP 的表单中检查该值.

the submit button also returns a post value if clicked, which you are checking in your form processing PHP.

if ($_POST['submitted']) {

在你的 curl 代码中，你已经遗漏了提交"的帖子变量.

in your curl code however you have left out the 'submitted' post variable.

如果这是您要查找的内容，请选中此答案旁边的复选标记.谢谢！
