Question

我试图将多个列表框值插入数据库，但无论如何这些值都没有插入到数据库中。我认为我的PHP文件存在一些问题

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

     $result = array();
       $i = 0;    
          foreach ($matches as $m) {

          if (!strlen($value)) {

        $which_state = $result[0]["which_state"];



      $insertSQL = sprintf("INSERT INTO test1 (States) VALUES (

我简化了你的代码，因为我假设你正在使用PDO或Msql将你的值作为字符串传递。它将所选项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" }

多个列表框值未使用PHP插入MySQL数据库
