我有一个表单,我可以获得一些不同的信息。但后来我有一个选择多个选项,我希望能够以1或0 / true或false将其发送到数据库。但它没有用。到目前为止,这是我的代码:
<select name="multipleSelect[]" multiple>
<option value="" disabled selected>Choose your option</option>
<option name="esea" value="esea">ESEA</option>
<option name="faceit" value="faceit">FaceIT</option>
<option name="matchmaking" value="matchmaking">Matchmaking</option>
</select>
<label>What are you looking to play?</label>
这是我的php:
$esea = 0;
$faceit = 0;
$matchmaking = 0;
foreach ( $_POST['multipleSelect'] as $value ) {
if ( $value == 'esea' ) { $esea = 1; }
if ( $value == 'faceit' ) { $faceit= 1; }
if ( $value == 'matchmaking' ) { $matchmaking= 1; }
}
// Sätt in dataN
$sql = "INSERT INTO users ( steamid, profilename, profileurl, avatar, region, age, ranks, esea, faceit, matchmaking, textarea1 ) VALUES (
'{$mysqli->real_escape_string($_POST['steamid'])}',
'{$mysqli->real_escape_string($_POST['profilename'])}',
'{$mysqli->real_escape_string($_POST['profileurl'])}',
'{$mysqli->real_escape_string($_POST['avatar'])}',
'{$mysqli->real_escape_string($_POST['region'])}',
'{$mysqli->real_escape_string($_POST['age'])}',
'{$mysqli->real_escape_string($_POST['ranks'])}',
$esea,
$faceit,
$matchmaking',
'{$mysqli->real_escape_string($_POST['textarea1'])}')";
$insert = $mysqli->query($sql);
我知道这段代码不起作用,但我不知道该怎么做才能让它发挥作用。我不想发送1或0,具体取决于是否选择了替代方案。

您的select
html代码需要具有name
属性才能将表单onSubmit发送到“后端”。
<select name="enterNameThatMakesSense" multiple> // <----- HERE
<option value="" disabled selected>Choose your option</option>
<option name="esea" value="1">ESEA</option>
<option name="faceit" value="1">FaceIT</option>
<option name="matchmaking" value="1">Matchmaking</option>
</select>
<label>What are you looking to play?</label>
答案 1 :(得分:1)
您的<select>
多重可选下拉列表必须是由name="NameThatMakesSense[]"
定义的数组
<select name="NameThatMakesSense[]" multiple>
这将返回一个名为$ _POST ['NameThatMakesSense']的字段,该字段本身是一个包含1个或多个值的数组,指示下拉列表中的哪些项目被选中。来自value=""
代码的<option>
属性
然后您需要预处理NameThatMakesSense
数组以从多选下拉列表中选择实际选择的值。
$esea = 0;
$esea = 0;
$esea = 0;
foreach ( $_POST['NameThatMakesSense'] as $value ) {
if ( $value == 'esea' ) { $esea = 1; }
if ( $value == 'faceit' ) { $faceit= 1; }
if ( $value == 'matchmaking' ) { $matchmaking= 1; }
}
$sql = "INSERT INTO users
( profilename, profileurl, avatar, region,
age, esea, faceit, matchmaking, textarea1 )
VALUES (
'{$mysqli->real_escape_string($_POST['profilename'])}',
'{$mysqli->real_escape_string($_POST['profileurl'])}',
'{$mysqli->real_escape_string($_POST['avatar'])}',
'{$mysqli->real_escape_string($_POST['region'])}',
'{$mysqli->real_escape_string($_POST['age'])}',
'{$mysqli->real_escape_string($_POST['ranks'])}',
$esea,
$faceit,
$matchmaking,
'{$mysqli->real_escape_string($_POST['textarea1'])}')";
