我正在尝试将从表单中获取的值存储到数据库中。我陷入困境,我不知道如何从foreach($questions as $row)
单独获取值并将它们存储到数据库中。
我的数据库表包含以下列:
variantid | stepid | questionid | newquestion | radiovalues | description
当我点击“保存”时,我试图将从视图中获取的所有详细信息保存到数据库中。每个foreach($questions as $row)
循环获得的每个值都需要存储在一个新行中。我想我应该使用insert_batch
,但我不知道如何将所有数据放入数组中。
我该如何处理?以下是我编写的代码。我没有在模型中写任何东西,因为我被卡住了。
<form id="theform">
<label for="variants">Variants:</label><br>
<?php
foreach($variants as $row)
{?>
<div class="form-group">
<input type="radio" name="variants[]" checked="true" id="variants" value="<?php echo $row->variantid ?>"/><?php echo $row->variantname ?><br/>
<?php }
?>
<div id='steplist'>
<?php
foreach($substeps as $row){
?>
<div id='img_div'>
<input type="radio" name="stepid[]" checked="true" id="stepid<?php echo $row->stepid; ?>" value="<?php echo $row->stepid; ?>"/><?php echo $row->stepname ?><br/>
</div>
<?php
foreach($questions as $each){
?><br><br>
<input type="text" name="questions[]" id="questions<?php echo $each->questionid; ?>" value="<?php echo $each->questionname; ?>" readonly/><br/>
<input type="hidden" name="questionid[]" id="questions<?php echo $each->questionid; ?>" value="<?php echo $each->questionid; ?>"/>
<a id="addq">Add question</a>
<input type="text" class="form-control" name="newquestion[]" style="font-weight:bold;width:100%;height:5%" id="new_questions<?php echo $each->questionid; ?>" /><br>
<div class="radio" id="answer">
<label style="font-weight:bold"><input type="radio" name="radioquestions[<?php echo $each->questionid; ?>][optradio]" value="no" required>no</label>
<label style="font-weight:bold"><input type="radio" name="radioquestions[<?php echo $each->questionid; ?>][optradio]" value="probably no" required>probably no </label>
<label style="font-weight:bold"><input type="radio" name="radioquestions[<?php echo $each->questionid; ?>][optradio]" value="unknown" required>unknown</label>
<label style="font-weight:bold"><input type="radio" name="radioquestions[<?php echo $each->questionid; ?>][optradio]" value="probably yes" required>probably yes</label>
<label style="font-weight:bold"><input type="radio" name="radioquestions[<?php echo $each->questionid; ?>][optradio]" value="yes">yes</label>
</div>
<textarea name="question1_text[]" id="description<?php echo $each->questionid; ?>" rows="3" cols="73"></textarea><br>
<?php
}
?>
<?php
}
?>
</div>
</form>
<input type='button' value='Save' class='save' id='save' />
<script>
$(document).ready(function(){
$("#save").click(function(e){
e.preventDefault();
$.ajax({
type:"POST",
url:"<?= base_url() ?>index.php/task/perform",
data:$('#theform').serialize(),
success:function(response){
alert(response);
}
});
});
});
这是我的控制者:
public function perform(){
var_dump($_POST);
$variantid = $this->input->post('variants');
$stepid = $this->input->post('stepid');
$questionid = $this->input->post('questions');
$newquestion = $this->input->post('newquestion');
$radioquestions = $this->input->post('radioquestions');
$question1_text = $this->input->post('question1_text');
$this->load->model('task_model');
$result= $this->task_model->performdata();
if($result){
echo "Data saved successfully";
}
}
感谢您的快速回复。我根据建议更改了代码。如何将这些值放入控制器并将其发送到数据库中?

foreach中的HTML无效,因为它缺少结束div标记,并且您的输入没有正确的name
属性,对于多个输入,您应该使用variants[]
而不是相同的ID。以这种方式做到:
<?php foreach ($variants as $row) { ?>
<div class="form-group">
<input type="radio" name="variants[]" checked="true" class="variants" value="<?php echo $row->variantid ?>"/><?php echo $row->variantname ?><br/>
</div>
<?php } ?>
