前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

Get $_POST from multiple checkboxes6个
有没有一种简单的
方法来
获取多个复选框的值并将它们存储在
数据库中?
<?PHP
if(isset($_POST['go'])){
$fruit = $_POST['fruit'].",";
echo $fruit;
// if you selected apple and grapefruit it would display apple,grapefruit
}
?>
<form method="post">
Select your favorite fruit:<br />
<input type="checkBox" name="fruit" value="apple" id="apple" /><label for="apple">Apple</label><br />
<input type="checkBox" name="fruit" value="pinapple" id="pinapple" /><label for="pinapple">Pinapple</label><br />
<input type="checkBox" name="fruit" value="grapefruit" id="grapefruit" /><label for="grapefruit">Grapefruit</label><br />
<input type="submit" name="go" />
</form>
如果给复选框指定相同的
名称,以[]结尾,则值将作为数组返回.
<input type="checkBox" name="fruit[]" value="apple" />
<input type="checkBox" name="fruit[]" value="grapefruit" />
然后在PHP …
if( isset($_POST['fruit']) && is_array($_POST['fruit']) ) {
foreach($_POST['fruit'] as $fruit) {
// eg. "I have a grapefruit!"
echo "I have a {$fruit}!";
// -- insert into database call might go here
}
// eg. "apple,grapefruit"
$fruitList = implode(',',$_POST['fruit']);
// -- insert into database call (for fruitList) might go here.
}
PS.请原谅明显的错误,这个例子可能会喊“我有一个苹果”……我没想到让这个例子足够聪明,以确定何时使用“a”,何时使用“an”:P
