我正在尝试将数据插入数据库，当我插入数据并按下提交按钮时，文本字段只是空，数据无法插入数据库 从我的代码中看到的一切看起来都不错，但我犯了错误？

答案 0 :(得分：0)
我看到你输入的输入名称不正确 从
更改模型中的输入名称 $this->input->post('mjesto odredista')致$this->input->post('mjesto_odredista') .etc
确保视图中的所有输入=模型中的输入。
答案 1 :(得分：0)
问题出在您的模型和视图中。
在模型中，当您在$this->input->post('Mjesto Odredista')内调用()时，您必须提供输入字段的名称。我想在这里你给了placeholder。
对于 VIEW ，对于某些输入字段，您没有提供name属性，例如Datum Povratka，Broj slobodnih mjesta，Opis等等。例如，
<div class='col-sm-4'>
<div class="form-group">
<label>Datum Povratka</label>
<div class='input-group date' id='datetimepicker1'>
<input type='text' class="form-control" />
<span class="input-group-addon">
<span class="glyphicon glyphicon-calendar"></span>
</span>
</div>
</div>
