php - 无法以多步骤形式获取其他步骤的日期值

Question

我有 3 步的多步形式。在第 2 步有日期输入框。我想在第三步获取日期值，但它显示错误。

  <input type="date" name="date" id="date" min="<?php echo date("Y-m-d"); ?>" class="datepicker" id="datepicker" />

 <input type="button" name="previous" class="previous action-button" value="Previous" />
    <input type="button" name="nextnew" id="nextnew" class="next action-button" value="Next" />

这是我的日期输入框，我有 2 个按钮可以转到下一步和上一步。

<?php

 $query5=mysql_query("select * from doctorbooking where aday='".$_REQUEST['date']."'");

 $query6=mysql_fetch_array($query5);

?>

我想通过在第二步中选择日期来从数据库表名称“doctorbooking”中检索日期值的值，但它显示错误。(未定义索引:日期)这是我的js。

   <script>
     //jQuery time
     var current_fs, next_fs, previous_fs; //fieldsets
    var left, opacity, scale; //fieldset properties which we will animate
     var animating; //flag to prevent quick multi-click glitches

      $(".next").click(function(){
    if(animating) return false;
animating = true;

current_fs = $(this).parent();
next_fs = $(this).parent().next();

//activate next step on progressbar using the index of next_fs
$("#progressbar li").eq($("fieldset").index(next_fs)).addClass("active");

//show the next fieldset
next_fs.show(); 
//hide the current fieldset with style
current_fs.animate({opacity: 0}, {
    step: function(now, mx) {
        //as the opacity of current_fs reduces to 0 - stored in "now"
        //1. scale current_fs down to 80%
        scale = 1 - (1 - now) * 0.2;
        //2. bring next_fs from the right(50%)
        left = (now * 50)+"%";
        //3. increase opacity of next_fs to 1 as it moves in
        opacity = 1 - now;
        current_fs.css({'transform': 'scale('+scale+')'});
        next_fs.css({'left': left, 'opacity': opacity});
    }, 
    duration: 800, 
    complete: function(){
        current_fs.hide();
        animating = false;
    }, 
    //this comes from the custom easing plugin
    easing: 'easeInOutBack'
    });
 });

   $(".previous").click(function(){
if(animating) return false;
animating = true;

current_fs = $(this).parent();
previous_fs = $(this).parent().prev();

//de-activate current step on progressbar
$("#progressbar li").eq($("fieldset").index(current_fs)).removeClass("active");

//show the previous fieldset
previous_fs.show(); 
//hide the current fieldset with style
current_fs.animate({opacity: 0}, {
    step: function(now, mx) {
        //as the opacity of current_fs reduces to 0 - stored in "now"
        //1. scale previous_fs from 80% to 100%
        scale = 0.8 + (1 - now) * 0.2;
        //2. take current_fs to the right(50%) - from 0%
        left = ((1-now) * 50)+"%";
        //3. increase opacity of previous_fs to 1 as it moves in
        opacity = 1 - now;
        current_fs.css({'left': left});
        previous_fs.css({'transform': 'scale('+scale+')', 'opacity': opacity});
    }, 
    duration: 800, 
    complete: function(){
        current_fs.hide();
        animating = false;
    }, 
    //this comes from the custom easing plugin
    easing: 'easeInOutBack'
});
});

  $(".submit").click(function(){
   return false;
  })

使用POST或GET代替Request

<?php

 $query5=mysql_query("select * from doctorbooking where aday='".$_POST['date']."'");

 $query6=mysql_fetch_array($query5);

?>
