PHP - MySql：如何使用其他选项存储和检索复选框值

Question

我使用复选框来获取和存储用户的兴趣。

存储这些数据在mysql数据库与逗号分隔

我的PHP代码retrive这些数据，并显示在HTML页面

<?php 

.... 

// Get data 
$result = profile($uname); 
$result['interest'] = explode(',', $result['interest']); 

print_r($result['interest']); // output: Array ([0] => option1 [1] => option2 [2] => option3) 

?> 

.... 

<div class="col-sm-6"> 
    <div class="form-check checkbox-style"> 
     <label class="label-weight">Interests</label><br> 
     <label class="form-check-label label-weight"> 
      <input type="checkbox" class="form-check-input" name="interest[]" onclick="return interest_validate(this);" id="selectall"><span class="check-label-pad"> Select all</span></label></label><label for="" class="opacity-set label-set" id="select-label"></label><br> 
     <label class="form-check-label label-weight"> 
      <input type="checkbox" class="form-check-input" name="interest[]" onclick="return option_select(this);" value="option1" <?php echo in_array('option1',$result['interest']) ? 'checked' : ''; ?>><span class="check-label-pad">Option 1</span></label><br> 
     <label class="form-check-label label-weight"> 
      <input type="checkbox" class="form-check-input" name="interest[]" onclick="return option_select(this);" value="option2" <?php echo in_array('option2', $result['interest']) ? 'checked' : ''; ?>><span class="check-label-pad">Option 2</span></label><br> 
     <label class="form-check-label label-weight"> 
      <input type="checkbox" class="form-check-input" name="interest[]" onclick="return option_select(this);" value="option3" <?php echo in_array('option3', $result['interest']) ? 'checked' : ''; ?>><span class="check-label-pad">Option 3</span></label><br> 
     <label class="form-check-label label-weight"> 
      <input type="checkbox" class="form-check-input" name="interest[]" id="other_checkbox" onclick=" return other_validate(this);" value="other"><span class="check-label-pad" >Other</span> &nbsp;&nbsp;</label><input type="text " class="text-style-other opacity-set" id="other-text" onblur="return other_text_validate();" /> 
     <label for="" class="opacity-set label-set" id="other-text-label"></label> 
    </div> 
</div> 

问题：在编辑模式下，我使用“in_array()”按照数据库值将默认值选中复选框。但如何检查 “其他”（检查附加图像）选项并显示它的值？其中 条件我需要在这里添加？如何在一个领域的“利息” 存储在数据库

Answer 1

您可以:分隔符插入数据。然后显示数据尝试以下代码：

例如：存储的数据是“option2，option3，other：xyz”;

<?php 
$result['interest']="option2,option3,other:xyz"; 
$result['interest']=explode(":", $result['interest']); 
$txt_value=""; 
if(count($result['interest']) >= 2) 
    $txt_value = $result['interest'][1]; 

$result['interest']=explode(",",$result['interest'][0]); 


?> 
<div class="col-sm-6"> 
    <div class="form-check checkbox-style"> 
     <label class="label-weight">Interests</label><br> 
     <label class="form-check-label label-weight"> 
      <input type="checkbox" class="form-check-input" name="interest[]" id="selectall"><span class="check-label-pad"> Select all</span></label></label><label for="" class="opacity-set label-set" id="select-label"></label><br> 
     <label class="form-check-label label-weight"> 
      <input type="checkbox" class="form-check-input" name="interest[]" value="option1" <?php echo in_array('option1',$result['interest']) ? 'checked' : ''; ?>><span class="check-label-pad">Option 1</span></label><br> 
     <label class="form-check-label label-weight"> 
      <input type="checkbox" class="form-check-input" name="interest[]" value="option2" <?php echo in_array('option2', $result['interest']) ? 'checked' : ''; ?>><span class="check-label-pad">Option 2</span></label><br> 
     <label class="form-check-label label-weight"> 
      <input type="checkbox" class="form-check-input" name="interest[]" value="option3" <?php echo in_array('option3', $result['interest']) ? 'checked' : ''; ?>><span class="check-label-pad">Option 3</span></label><br> 
     <label class="form-check-label label-weight"> 
      <input type="checkbox" class="form-check-input" name="interest[]" id="other_checkbox" <?php echo in_array('other', $result['interest']) ? 'checked' : ''; ?>><span class="check-label-pad" >Other</span> &nbsp;&nbsp;</label><input type="text " class="text-style-other opacity-set" value="<?=$txt_value?>" id="other-text"/> 
     <label for="" class="opacity-set label-set" id="other-text-label"></label>
