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 "<>"
.

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.
