Question

我有一个应用程序，我需要从列表复选框中取出项目并将它们解析到我的数据库中。目前我通过循环选项并在每个选项前放置一个复选框并在每个输入中使用名称example []来将它们收集到一个数组中。问题是我如何将该数组发送到jquery，然后发送到php解析文件，以便它将被记录在数据库中作为由逗号分隔的列表，以便我可以将该列表调用到网站上的另一个字段？ / p>

所以这就是我所拥有的，但它不起作用

$chart_query = mysql_query("SELECT id, title FROM songs WHERE team_name='$team_name' ORDER BY title ASC");
while($row = mysql_fetch_array($chart_query)){
    $song_id = $row['id'];
    $song_title = $row['title'];

    $song_chart .= '<div align="left" class="song_links"><input class="allcharts" type="checkbox" name="charts[]" value="'.$song_title.'" />&ndash;<a href="http://' . $dyn_www . '/template.php?id='.$song_id.'" style="color:white; text-decoration:none; margin-left:5px;">'.$song_title.'</a></div>';
}

jquery ......

function post_song_list(){
    var allcharts = $(".allcharts").each().val();
    var team_name = $("#team_name").val();
    var list_date = $("#list_date").val();

    if (allcharts = ""){
        alert("You must select at least one song");
    }else{
        $.post("scripts/post_song_list.php", {allcharts: allcharts, team_name: team_name, list_date: list_date}, function(data){
            $(".allcharts").val("");
            $("#team_name").val("#team_name");
            $("#list_date").val("");
        });
    }
}

php解析......

if(isset($_POST['team_name']) != '' && isset($_POST['list_date']) != '' && isset($_POST['charts']) != ''){
    if(isset($_POST['team_name'])){
        $team_name = $_POST['team_name'];
             $team_name = stripslashes($team_name);
             $team_name = strip_tags($team_name);
             $team_name = mysql_real_escape_string($team_name);
             $team_name = str_replace("'", "&#39;", $team_name);
    }
    $sql = mysql_query("SELECT admin_id FROM myTeams WHERE team_name=$team_name");
    while($row = mysql_fetch_assoc($sql)){
        $admin_id=$row['admin_id'];
        if(isset($_SESSION['idx']) != $admin_id) {
            $msgToUser = '<br /><br /><font color="#FF0000">Only Team Administrators can do that!</font><p><a href="register.php">Join Here</a></p>';
            include_once '../msgToUser.php'; 
            exit(); 
        }
    }
    if(isset($_POST['list_date']))
    $list_date = $_POST['list_date'];
             $list_date = stripslashes($list_date);
             $list_date = strip_tags($list_date);
             $list_date = mysql_real_escape_string($list_date);
             $list_date = str_replace("'", "&#39;", $list_date);
             $list_date = "".$list_date."";
    }

    if(isset($_POST['charts']) != ""){ 
    $checkboxes = isset($_POST['charts']) ? (array)$_POST['charts'] : array();
    $charts = implode('<br />', $checkboxes);
        $charts = stripslashes($charts);
        $charts = strip_tags($charts);
        $charts = mysql_real_escape_string($charts);
        $charts = str_replace("'", "&#39;", $charts);

    $sql_charts = mysql_query("INSERT INTO list (date, team_name, song_list) VALUES ('$list_date','$team_name','$charts')") or die (mysql_error());
    echo "<span>List Uploaded</span>";
}

有人能告诉我哪里出错了吗？它不会转到解析文件。

Answer 1

不覆盖jquery部分，但假设它是正常的表单提交：

HTML：

<input type="checkbox" name="cb[]" value="1" />
<input type="checkbox" name="cb[]" value="2" />
etc...

PHP：

<?php

$checkboxes = isset($_POST['cb']) ? (array)$_POST['cb'] : array();

$string = implode(',', $checkboxes);
$ready_for_sql = mysql_real_escape_string($string);

$sql = "INSERT INTO yourtable (checkboxfield) VALUES ('$ready_for_sql')";
$result = mysql_query($sql) or die(mysql_error());

当然，根据您将如何使用这些值，您可能不希望将它们存储为以逗号分隔的列表。如果您需要引用该列表中的各个值，那么最好使用子表分别存储每个值。

好吧，jquery可以使用表单序列化函数来抓取复选框：

<form class="checkbox-form">
<input type="checkbox" class="chk" name="check[]" value="val1" />
<input type="checkbox" class="chk" name="check[]" value="val2" />
<input type="checkbox" class="chk" name="check[]" value="val3" />
<input type="button" class="send" value="Send" />
</form>
<script type="text/javascript">
function checkbox_callback(){
     $(".chk").each(function(index, domElem){
     //here you grab each checkbox element and do anything you want
     //(i think you want to do some validation here)
     });
}

//To send to php you can use ajax
$(".send").click(function(){
    //here you can call the checkbox function callback
    valid = checkbox_callback();
    if(valid){
       $.ajax({
            type: "POST",
            url: "yourphp.php",
            data: $(".checkbox-form").serialize()
       });
    }
});
</script>

在php端只需调用implode或join函数：

  $str = implode(",", $_POST["check"]);
  $str = join(",", _POST["check"]; //is the same function.

将复选框数组解析为数据库时出现问题
