~~/tr~~<br>
~~/table~~<br>
~~/form~~<br>
~~/body~~<br>

<br><br><br>

注意：此处未使用html标记<所以我使用~~而不是<>。


主题：这个程序工作正常..但是当我提交更多一个复选框，被检查的项目不在 CHECKED 。
在提交表单后，只选中一个项目。< br>< br>

NOTE: html tag<> not used here. So i used "~~" instead of "<>".

Subject: This program working perfectly.. But when i submitting with MORE THAN ONE check box., the checked items is not in CHECKED.
Only one item is checked., after submitting the form.<br><br>

例如：

当我选中蓝色和红色颜色时，它在提交后仅选中红色所以我需要解决这个错误。帮助我！

For Example:
When i check 'Blue' and 'Red' color., it Checked only 'Red' color after Submitting. So i need the solution for this error. Help Me!.

推荐答案

您应该将复选框声明为数组

you should declare your checkbox as arrays

<input type='checkbox' name='color_list[]' value="red">
<input type='checkbox' name='color_list[]' value="blue">
<input type='checkbox' name='color_list[]' value="green">

，以便在获得 $ _ POST ['color_list'] 你将选择颜色数组。你可以这样做：

so that after you get it $_POST['color_list'] you'll have the array of colors selected. you could do something like this:

$colors_selected = $_POST['color_list'];

然后只需使用 implode（）。我希望这有助于。

then just use some function like implode(). I hope this helps.
