我正在尝试将多个列表框值插入到数据库中，但无论如何这些值都没有被插入到数据库中。我认为我的 PHP 文件有问题
这是我的 Javascript 文件
$(document).ready(function() {
jQuery("#skill-form").validationEngine();
$("#skill-form").on("submit",function(e) {
e.preventDefault();
if($("#skill-form").validationEngine('validate')) {
var form_data = $( "form" ).serialize();
$.post( "insert.php",{form_values : form_data},function( data ) {
var Data = jQuery.parseJSON(data);
});
} else {
return false;
}
});
});
这是我的 HTML 文件

最佳答案
我已经简化了您的代码，因为我假设您正在使用 PDO 或 Msql 将您的值作为字符串传递。它将所选项目连接为数组中的字符串，并使用 execute() 将数组插入数据库。
<?php
if(isset($_POST['submit'])){//to run PHP script on submit
if(isset($_POST['which_state'])){
$states = implode(",",$_POST['which_state']);
$paramArray = array($states);
}
$insertSQL = "INSERT INTO test1 (States) VALUES (?)";
$query_insert = $db->prepare( $insertSQL );
$result_insert = $query_insert -> execute($paramArray);
}
?>
<form method="POST" action="#">
<select name="which_state[]" id="which_state" class="form-control" multiple="multiple" data-validation-engine="validate[required]" data-errormessage-value-missing="Please Select any one option" >
<option value="Colorado">Colorado</option>
<option value="Florida">Florida</option>
<option value="Illinois">Illinois</option>
<option value="Michigan">Michigan</option>
<option value="Minnesota">Minnesota</option>
<option value="Ohio">Ohio</option>
<option value="Texas">Texas</option>
<option value="Wisconsin">Wisconsin</option>
</select>
<input type="submit" name="submit" value="Submit">
示例查询 INSERT INTO test1 (States) VALUES (?)
示例值 array(1) { [0]=> string(16) "Florida,Illinois"
