我需要一双新的眼睛来看看这个

我直接从我的一把旧小提琴上取下代码,在一个大学厨房的网站上展示照片。然而,它只显示了一个。当我在php中包含bootstrap和函数时,它似乎并没有读取它!为什么会这样

我的php看起来像这样

您尚未在页面中包含jQuery,您正在脚本中使用jQuery,但根本没有加载它


找到这些问题的一个好方法是在使用chrome时按F12键,使用开发者栏,然后在网络上可以看到加载了哪些文件,如果有javascript错误,可以在控制台中查看。

这与
$subfolder=$\u POST[“category”]有关-
注意:未定义索引:类别
-POST失败,并且依赖于表单(?)。可能是GET,但不确定从何处填充。@RachelGallen Bootstrap使用jQuery,而您正在页面中使用jQuery。如果您也检查控制台日志,它会清楚地显示:未捕获错误:Bootstrap的JavaScript需要jQuery
//Reference https://jsfiddle.net/RachGal/fs9u6mwe/1/

$(document).ready(function() {

  //INDEX IMAGES SLIDER
  $(function slider() {

    //configuration
    var width = 360;
    var speed = 1000;
    var pause = 3000;
    var current = 1;


    //cache DOM
    var $slider = $('#slider');
    var $slides = $slider.find('#slides');
    var $slide = $slides.find('.slide');


    setInterval(function() {
      //move image the defined width and speed to the left
      $slides.animate({
        'margin-left': '-=' + width
      }, speed, function() {
        //count number of slides and loop back to first from last
        current++;
        if (current === $slide.length) {
          current = 1;

          $slides.css('margin-left', 0);
        }
      });
    }, pause);
  });
}

);
