[英]dynamic show and hide of radio buttons based on output of another radio button
[英]Changing the image output based on radio button output
再会,
我正在研究我的这个项目,但不幸的是我还不够熟练,无法解决我一直试图解决一段时间的以下问题。 我有一个网页,显示某人需要消耗多少卡路里才能达到他们的训练目标。 基于 3 个选项无线电输入选择,我想根据他们所做的选择在 output 页面上显示 3 个不同的图像。 这可以是减肥、维持或增肌。
代码如下:
目标输入代码:
<!-- Goal -->
<div class="row px-md-5 mrow" id="rowtwo">
<div class="col-12 py-5">
<div class="text-center">
<h2 class="text-primary">2. Wat is je doel?</h2>
</div>
</div>
<div class="col-12 col-md-12">
<ul class="row radio-group-goal d-flex flex-stretch p-0 m-0">
<li class="radio col-md-6 selected d-flex flex-stretch mb-2" data-goal="Afvallen / Lager vetpercentage" style="list-style: none;">
<div class="innerradio d-flex flex-column content shadow-sm rounded p-4 d-flex flex-row bg-white w-100 greenborder">
<h6 class="text-left"><i class="fas fa-check-circle hidebtn text-success mr-1"></i> <i class="fas fa-weight text-primary mr-2"></i> Afvallen / Lager vetpercentage</h6>
<!-- <p class="mb-0 text-left" style="font-size: 12px; line-height: 14px">minder kcal/koolhydraten</p> -->
</div>
</li>
<li class="radio col-md-6 d-flex flex-stretch mb-2" data-goal="Gezonde levensstijl" style="list-style: none;">
<div class="innerradio d-flex flex-column content shadow-sm rounded p-4 d-flex flex-row bg-white w-100">
<h6 class="text-left mb-0"><i class="fas fa-check-circle hidebtn text-success mr-1"></i> <i class="fas fa-carrot text-primary mr-2"></i> Gezonde levensstijl</h6>
<!-- <p class="mb-0 text-left" style="font-size: 12px; line-height: 14px">Gezond</p> -->
</div>
</li>
<li class="radio col-md-6 d-flex flex-stretch mb-2" data-goal="Aankomen / Meer spiermassa" style="list-style: none;">
<div class="innerradio d-flex flex-column content shadow-sm rounded p-4 d-flex flex-row bg-white w-100">
<h6 class="text-left mb-0"><i class="fas fa-check-circle hidebtn text-success mr-1"></i> <i class="fas fa-dumbbell text-primary mr-2"></i> Aankomen / Meer spiermassa</h6>
<!-- <p class="mb-0 text-left" style="font-size: 12px; line-height: 14px">muscle</p> -->
</div>
</li>
</ul>
</div>
output 的代码:
<div class="col-12 col-md-6">
<div class="row">
<div class="col-12 col-md-6 mb-4 d-flex flex-stretch">
<div class="youchoose-box px-4 py-5 d-flex align-items-center justify-content-center flex-column bg-white rounded shadow-sm w-100" style="border:1px solid white;">
<i class="fas fa-trophy text-center text-primary mb-2"></i>
<!-- <p class="mb-0 text-center">Doel</p> -->
<h5 class="text-primary text-center">
<?php echo $_POST['radio-value'];?>
</h5>
</div>
</div>
//The image I want to change based on the radio value:
<div class="container pb-5">
<div class="row">
<div class="col-12 d-flex align-items-center justify-content-center">
<div class="d-flex align-items-center justify-content-center rounded shadow-sm">
<img src="<?php echo home_url();?>/wp-content/uploads/2020/12/Macro-split.png">
</div>
</div>
</div>
</div>
<!-- save values and send to next pages -->
<input type="hidden" id="radio-value" name="radio-value" value="<?php echo $_POST['radio-value']?>" />
我希望你能指导我正确的方向,因为我现在了解 Javascript 的基础知识。
先感谢您!
假设您的值在$_POST['radio-value']
中通过,执行此操作的基本方法是使用if
语句检查是否设置了 3 个值之一,然后设置该值对应的图像:
//The image I want to change based on the radio value:
<?php
$image = 'default.png';
if (isset($_POST['radio-value'])) {
if ($_POST['radio-value'] == 'value for image 1') {
$image = 'value1image.png';
} else if ($_POST['radio-value'] == 'value for image 2') {
$image = 'value2image.png';
} else if ($_POST['radio-value'] == 'value for image 3') {
$image = 'value3image.png';
}
}
?>
然后在您的图像 src 中:
<img src="<?php echo home_url();?>/wp-content/uploads/2020/12/<?php echo $image;?>">
