PHP / AJAX复选框值(PHP / AJAX checkbox values)
我正在尝试获取所有选中的复选框值并使用AJAX将它们解析为我的php functin。
我使用foreach尝试获取已选中复选框的每个id。
我的问题是，当我尝试更新数据库时，它不会返回'1'，我会在成功时回复。
当我把我的foreach代码拿出来时，它有效。
我的删除按钮是：
<form class="form -dark" id="form-inline" method="POST"> <div class="btn-group"> <button type="button" onclick="deleteSelectedTokens()" class="btn -dark" style="margin-left: 5px;" title="Delete all selected tokens"><i class="fa fa-trash"> </i></a> </div> </form>我的复选框html / php代码是：
<table class="table -dark -striped"> <thead> <tr> <th style="text-align: center;"><input type="checkbox" id="selectall"/></th> <th style="text-align: center;">Token</th> <th style="text-align: center;">Date/Time Generated</th> <th style="text-align: center;">Status</th> <th style="text-align: center;">Durbaility</th> </tr> </thead> <tbody> <tr> <?php $username = $_SESSION['username']; $token_result = mysqli_query($con, "SELECT id, token, used, time_generated, durability FROM tokens WHERE user_id = '$username' ORDER BY used"); if(mysqli_num_rows($token_result) > 0) { while($token_row = mysqli_fetch_array($token_result)) { $result = array($token_row['durability']); $sub_struct_month = ($result[0] / 30) ; $sub_struct_month = floor($sub_struct_month); $sub_struct_days = ($result[0] % 30); $sub_struct = "<i>".$sub_struct_month."</i> month(s) <i>".$sub_struct_days."</i> day(s)"; echo ' <tr style="text-align: center;"> <td> <center><input type="checkbox" id="checkedTokens" class="checkbox" value='.($token_row['id']).'></center> </td> <td> '.$token_row['token'].' </td> <td> '.($token_row['time_generated']).' </td> <td> '.($token_row['used'] == "0" ? "<span class='label label-primary'><i class='fa fa-check'></i> Valid </span>" : "<span class='label label-primary'><i class='fa fa-fa fa-times'></i> Used </span>").' </td> <td> '.$sub_struct.' </td> '; } }else{ ?> <tr> <td colspan="12" style="padding: 30px;"> <div class="alert -dark"> <div class="alert-icon _text-danger"> <i class="fa fa-exclamation-circle"></i> </div> No tokens in your account </div> </td> </tr> <?php } ?> </tr> </tbody>注意我需要使用foreach来获取每个复选框的值，这样当我按下删除按钮时我可以删除所选的复选框值。
我的AJAX发送到PHP的功能是：
<script> function deleteSelectedTokens() { var selectedTokens = document.getElementById("checkedTokens").value; $.ajax({ type: "POST", url: "includes/form_submit.php", data: { deleteSelectedTkns: true, checked_id: selectedTokens }, success: function(msg){ if(msg == 1) { update_myDays_success(); } else { general_error_forms(); } }, }); return false; } </script>我认为问题是Javascript ...当我得到复选框的值并发布它们时，我认为它只在checkedTokens id中得到1个值。
我的php接收代码（这不是问题）：
$username = $_SESSION['username']; $selectedTokens = mysqli_real_escape_string($con, $_POST['checked_id']); foreach($selectedTokens as $id) { $doUpdateDelete = 'DELETE FROM tokens WHERE id = "'.$id.'" AND user_id = "'.$username.'"'; $result = $con->query($doUpdateDelete) or die("Error"); if($result) { echo '1'; } else { echo 'Failed'; } }我的console.log没有错误。 就像我说的，我认为这是用于获取我的复选框的值没有获得所有值的javascript代码。
I'm trying to get all checked checkbox values and parse them to my php functin using AJAX.
I use foreach to try and get each id of the checked checkbox's.
My problem is that when I try and update the database, it doesn't return '1' which I echo upon success.
When I take my foreach code out, it works.
My delete button is :
<form class="form -dark" id="form-inline" method="POST"> <div class="btn-group"> <button type="button" onclick="deleteSelectedTokens()" class="btn -dark" style="margin-left: 5px;" title="Delete all selected tokens"><i class="fa fa-trash"> </i></a> </div> </form>My checkbox html/php code is :
<table class="table -dark -striped"> <thead> <tr> <th style="text-align: center;"><input type="checkbox" id="selectall"/></th> <th style="text-align: center;">Token</th> <th style="text-align: center;">Date/Time Generated</th> <th style="text-align: center;">Status</th> <th style="text-align: center;">Durbaility</th> </tr> </thead> <tbody> <tr> <?php $username = $_SESSION['username']; $token_result = mysqli_query($con, "SELECT id, token, used, time_generated, durability FROM tokens WHERE user_id = '$username' ORDER BY used"); if(mysqli_num_rows($token_result) > 0) { while($token_row = mysqli_fetch_array($token_result)) { $result = array($token_row['durability']); $sub_struct_month = ($result[0] / 30) ; $sub_struct_month = floor($sub_struct_month); $sub_struct_days = ($result[0] % 30); $sub_struct = "<i>".$sub_struct_month."</i> month(s) <i>".$sub_struct_days."</i> day(s)"; echo ' <tr style="text-align: center;"> <td> <center><input type="checkbox" id="checkedTokens" class="checkbox" value='.($token_row['id']).'></center> </td> <td> '.$token_row['token'].' </td> <td> '.($token_row['time_generated']).' </td> <td> '.($token_row['used'] == "0" ? "<span class='label label-primary'><i class='fa fa-check'></i> Valid </span>" : "<span class='label label-primary'><i class='fa fa-fa fa-times'></i> Used </span>").' </td> <td> '.$sub_struct.' </td> '; } }else{ ?> <tr> <td colspan="12" style="padding: 30px;"> <div class="alert -dark"> <div class="alert-icon _text-danger"> <i class="fa fa-exclamation-circle"></i> </div> No tokens in your account </div> </td> </tr> <?php } ?> </tr> </tbody>Notice I need to use foreach to get each check checkbox value so I can remove the selected ones when I press the delete button.
My AJAX send to PHP function is :
<script> function deleteSelectedTokens() { var selectedTokens = document.getElementById("checkedTokens").value; $.ajax({ type: "POST", url: "includes/form_submit.php", data: { deleteSelectedTkns: true, checked_id: selectedTokens }, success: function(msg){ if(msg == 1) { update_myDays_success(); } else { general_error_forms(); } }, }); return false; } </script>I think the problem is the Javascript... when I get the value of the checkboxes and post them, i think it's only getting 1 value inside the checkedTokens id.
My php receive code (this is not the problem) :
$username = $_SESSION['username']; $selectedTokens = mysqli_real_escape_string($con, $_POST['checked_id']); foreach($selectedTokens as $id) { $doUpdateDelete = 'DELETE FROM tokens WHERE id = "'.$id.'" AND user_id = "'.$username.'"'; $result = $con->query($doUpdateDelete) or die("Error"); if($result) { echo '1'; } else { echo 'Failed'; } }My console.log has not errors. Like I said, i think it's the javascript code for getting the value of my checkbox's not getting all the values.
