需要选项值才能处理我的代码

Question

你好，我有一个 php 网站，我试图将一个元素作为可选值，但我不知道它是如何工作的。

查看第一张图片 1
![第一张图片][1] 它显示在所有页面上，但我想让它可选显示和隐藏

这是我添加代码添加页面部分的代码

见第二张图片

代码是

<label for="name-in" class="col-md-3 label-heading">Color Name</label>  
<div class="col-md-9">
        <select name="is_colorname" class="form-control">
            <option value="1">Yes</option>
            <option value="0">No</option>
        </select>
    </div>

值 Yes 显示彩色文本，No 隐藏

现在这段代码需要显示和隐藏

    <?php if (!$is_colorname) : ?><?php if(!empty($bstf)) { echo $bstf; } echo '</p><br><br>'; ?>
    <p class="card-title center-align comic wishesed">
    <?php if($wish!="love" ) { 
        if($wish=="bestf" ) {

如何显示和隐藏彩色文字

Answer 1

提交表单后，您需要检查代表 'color name' 字段的请求变量，并呈现或不呈现该元素，就像您已经对 $is_doublename[=12= 所做的那样]

代码将是这样的：

<?php if (!$is_colorname) : ?>
    // Html code to print the name
<?php endif ?>;
