将单选按钮转换为复选框
问题描述：
I was wondering how to convert my radio buttons into checkboxes because I want to insert multiple options for the same record... for example: I want a game to be in the "Strategy" and "Action" category, so only a checkbox can make me achieve that.
here is my code for inserting a game with radio buttons:
<?php
session_start();
if(!isset($_SESSION['user_name'])){
header("location:login.php");
}
else {
?>
<?php
include("../includes/connect.php");
$action_status = 'unchecked';
$sports_status = 'unchecked';
if(isset($_POST['submit'])){
$game_name = $_POST['game_name'];
$game_category = $_POST['game_category'];
$game_keywords = $_POST['game_keywords'];
$game_image = $_FILES['game_image']['name'];
$image_tmp = $_FILES['game_image']['tmp_name'];
$game_code = $_FILES['game_code']['name'];
$code_tmp = $_FILES['game_code']['tmp_name'];
$game_file = $_FILES['game_file']['name'];
$file_tmp = $_FILES['game_file']['tmp_name'];
$game_desc = $_POST['game_desc'];
if($game_name=='' or $game_category=='' or $game_keywords=='' or $game_image=='' or $game_code=='' or $game_file==''){
echo "<script>alert('Please enter all the fields below!')</script>";
exit();
}
else {
$path = "../games/$game_name";
mkdir("$path", 0777);
move_uploaded_file($image_tmp,"../images/games_images/$game_image");
move_uploaded_file($code_tmp,"$path/$game_code");
move_uploaded_file($file_tmp,"$path/$game_file");
$insert_query = "insert into games (game_name,game_category,game_keywords,game_image,game_code,game_file,game_desc) values ('$game_name','$game_category','$game_keywords','$game_image','$game_code','$game_file','$game_desc')";
if($game_category == '3d'){
$three_d_status = 'checked';
}else if($game_category == 'action'){
$action_status = 'checked';

$adventure_status = 'checked';

}else if($game_category == 'girls'){
$girls_status = 'checked';
}else if($game_category == 'holidays'){
$holidays_status = 'checked';
}else if($game_category == 'hidden_objects'){
$hidden_objects_status = 'checked';
}else if($game_category == 'motocross'){
$motocross_status = 'checked';
}else if($game_category == 'multiplayer'){
$multiplayer_status = 'checked';
}else if($game_category == 'new'){
$new_status = 'checked';
}else if($game_category == 'puzzle'){
$puzzle_status = 'checked';
}else if($game_category == 'racing'){
$racing_status = 'checked';
}else if($game_category == 'fps'){
$fps_status = 'checked';
}else if($game_category == 'space'){
$space_status = 'checked';
}else if($game_category == 'sports'){
$sports_status = 'checked';
}else if($game_category == 'strategy'){
$strategy_status = 'checked';
}else if($game_category == 'stunt'){
$stunt_status = 'checked';
}else if($game_category == 'top_rated'){
$top_rated_status = 'checked';
}else if($game_category == 'words'){
$words_status = 'checked';
}else if($game_category == 'zombies'){
$zombies_status = 'checked';
}
if(mysql_query($insert_query)){
echo "<script>alert('The Game Uploaded Successfully!')</script>";
echo "<script>window.open('view_games.php','_self')</script>";
}
}
}
?>

Anyone?
EDIT: While solving this problem I found an error in my code, I have much more then "action" and "sports" categories in my website, I forgot to add more categories to this lines "$action_status = 'unchecked';", but for some reason I didn't got any errors, and everything worked perfectly... strange O.o
答
If all you are looking to do is replace your RADIO buttons with CHECKBOXES, just change the HTML to reflect that, like so:
<input class="radio" type="checkbox" name="game_category[]" value="action"<?php print $action_status; ?>/><span>Action</span><br/>
You will then need to change all the "else if"'s in your PHP to just "if"'s, as you can iterate over multiple values, like so:
if($game_category == 'multiplayer'){
$multiplayer_status = 'checked';
}
if($game_category == 'new'){
$new_status = 'checked';
}
答
If you got only one, maybe the NAME element must be an array :
Checkbox:<input type="checkbox" checked="checked" name="myCheck[]">

The solution:
I change this line for example from this:
<input class="radio" type="radio" name="game_category" value="3d"<?php print $three_d_status; ?>/><span>3D</span><br>
into this:
<input class="checkbox" type="checkbox" name="game_category[]" value="3d"<?php print $three_d_status; ?>/><span>3D</span><br>
Then, I edited the if statements from this:
if($game_category == '3d'){
$three_d_status = 'checked';
}else if($game_category == 'action'){
$action_status = 'checked';
}
Into this:
if($game_category == '3d'){
$three_d_status = 'checked';
}
if($game_category == 'action'){
$action_status = 'checked';
}
and finally I changed this line from this:
$game_category = $_POST['game_category'];
Into this:
$game_category = implode(",",$_POST['game_category']);
Hope that helped someone out there :)
