I have a php variable "echo $id". Now I want to use the $_POST method to post the variable. I just want to know how to do this for a variable because $_POST[$id] does not work?
推荐答案
使用$ _POST方法,您必须将其发布到某个东西.
With the method $_POST you must be posting to something.
我对您的建议是创建一个表单,然后将该表单转到您要发布到的文件:
My suggestion to you is to create a form, then have the form going to the file you wish to post to:
是这样的:
echo '<form action = "fileToPostTo.php" method = "post">
<input type = "text" hidden value = "'.$id.'" />
</form>';
然后在通过jquery或javascript加载文档时提交表单.
And then submit the form when the document loads through jquery or javascript.
