通过POST发送给PHP的值都是空字符串

Question

I have the following form:

<FORM action="http://url.to.mysite.com/doc.php" method="post">
    <INPUT type="text" id="name">
    <INPUT type="text" id="id">
    <INPUT type="submit" value="Send">
    </P>
 </FORM>

Unfortunately, whatever is typed into the text fields, the PHP script receives only empty strings in every $_POST variable. All of the variables are set, just empty. What can be the cause of that?

Answer 1

You are missing the name properties in your html:

<FORM action="http://url.to.mysite.com/doc.php" method="post">
    <INPUT type="text" name="name" id="name">
    <INPUT type="text" name="id" id="id">
    <INPUT type="submit" value="Send">
</FORM>
