HTML选择表单，POST没有值

Question

I am having problem and I spent lot of time trying to solve it but I couldn't find solution.

So I got this HTML form:

<form method="post" action="register.php" name="registerform">

<label for="signup_game_name">Game Name</label> <br>
<select id="signup_game_name" class="reg_input" size="1" name"game_id" required>

<option value="2">Game1</option>
<option value="3">Game2</option>

</select>
<br><br>



<label for="signup_input_teamname">Team name </label> <br>
<input id="signup_input_teamname" class="reg_input" type="text"  name="team_name" required /> 
<br><br>


<input type="submit"  name="register" value="Signup" /> </form>

I used php class (function) to generate "options" for select form (i just posted results of that function above). Its simple function: grab value from GET method and use it to get values from database and create "options" for select form.

After i click submit button on my form I can use $_POST['team_name'] in my class but $_POST['game_id'] is unusable (its empty). I get error: Notice: Undefined index: game_id

I know i am missing something but i cant find it.

Answer 1

这是<select>标记中名称和“ game_id”之间的=符号：

<select id="signup_game_name" class="reg_input" size="1" name="game_id" required>

Answer 2

you are missing an =

<select id="signup_game_name" class="reg_input" size="1" name"game_id" required>

should be

<select id="signup_game_name" class="reg_input" size="1" name="game_id" required>

one other thing... in your question you mention a function that uses GET to retrieve data, but your'e using POST in your form. Might want to check that too.

Answer 3

You forgot to put equals sign in "name":

name="game_id"
