PHP-MySql : How to store and retrieve checkbox value with other option

Question

我使用复选框来获取和存储用户的兴趣。

将这些数据以逗号分隔存储在数据库mysql中

我的 php 代码用于检索这些数据并在 html 页面中显示

<?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">

Answer 1

您可以使用 : 分隔符插入数据。然后显示数据尝试以下代码:

例子: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"/>
