所以我制作了这段代码
<div class="row">
<div class="col-md-4">
</div>
<div class="col-md-4">
<div class="form-group">
<label for="user_name">Username</label>
<input type="text" id="user_name" class="form-control" placeholder="Enter Username">
</div>
<div class="form-group">
<label for="mac_address">Mac Address</label>
<input type="text" name="mac_address" id="mac_address" class="form-control" placeholder="Enter Mac Address">
</div>
<a class="btn btn-default" onclick="load('<?php echo $base_path?>user.php?action=index')">Back</a>
<button type="submit" class="btn btn-success" onclick="user_store()">Save</button>
</div>
<div class="col-md-4">
</div>
</div>
但是当我向数据库提交我的数据时，它显示的错误就像这个“意外的令牌＆lt; JSON在0位”你们可以帮助我解决这个错误吗？
