?>
<style>
#hideall {
    display: none;
    opacity: 0.7;
    position: fixed;
    height: 100%;
    width: 100%;

    </div>


    <div class="">

            <div>
                <span class="remainWords"><?php //echo count($words);?></span> oxxxxxxxxxxxxxxxf <?php //echo $totalWords;?>
            </div>

            <div>
                <?php
                echo $this->Html->image("comic_edit.png",
                                        array(
                                            "alt" => "Pareto List",
                                            "id" => "paretoList",
                                            'url' => "javascript:;"
                                        )
                                    );
                ?>
            </div>
        </div>
    </div>




    <div class="container"><div class="row">






<?php



    foreach($worddeck as $worcard)
    {

<script type="text/javascript">
$(document).ready(function(){


   $( ".btn-danger" ).click(function(){
        console.log("Red Button");
        var toclose = $(this).parent().parent();
        $.ajax({
          url: "../img/media.jpg",
        }).done(function() {
            console.log( "The act has been done");
            toclose.toggle();
          });
   }); 


   $( ".btn-success" ).click(function(){
        console.log("Red Button");
        var toclose = $(this).parent().parent();
        $.ajax({
          url: "../img/media.jpg",

  $( ".xy" ).click(function(){

    $(this).find("#enside1").toggle();

</script>

现在，我需要做的是，这。当用户点击 Acertei 按钮时，我需要执行 correctAnswer 函数。我对PHP和CakePHP非常新，所以我真的很困惑，当点击按钮时如何做到这一点。

Now, what I need to do is, this. When the user click on the Acertei button, I need to execute the function correctAnswer. I am very new to PHP and CakePHP so I am really confused about how to do this when a button is clicked. Any advice please?

推荐答案

您有

<div id="cntrol1">
    <button type="button" id="2" class="a btn btn-success mr5 btn-lg">Acertei</button>
    <button type="button" id="2" class="e btn btn-danger mr5 btn-lg">Errei</button>
</div>

您应该为每个按钮使用不同的ID。

You should use different IDs for each button.

您可以使用ajax调用 correctAnswer 函数：

You can call the correctAnswer function with ajax:

将按钮更改为

<button type="button" id="2" data-word="<?php $worcard['unique_wordsforcards']['en_word'] ?>" class="a btn btn-success mr5 btn-lg">Acertei</button>

然后在 $（document）.ready（）

  $(document).ready(function(){
      $(".btn-success").click(function(){
          var word = $(this).data('word');
          $.post('/flip2/correct.json', { word: word })
          .done(function(data) {
              alert('Saved');
          });

我不知道用户部分是如何工作的，你应该在会话中有这个，而不是发送到函数。我硬编码用户89，并为你添加一个方法发送单词。

I am not sure how the user part works. You should probably have that in the session, and not sent to the function. I hardcoded user 89 and added a way for you to send the word.
