包括php中的bootstrap和js

Including bootstrap and js in php

本文关键字：js bootstrap 中的 php 包括      更新时间：2023-09-26

我需要一双全新的眼睛来看待这个！

我直接从我的一把旧小提琴上取了代码https://jsfiddle.net/RachGal/fs9u6mwe/1/在大学厨房里展示照片。然而，它只显示了一个。当我在php中包含bootstrap和函数时，它似乎没有读取它！为什么会这样？

我的php看起来像这个

<?php
echo "<html><head><meta charset='utf-8'>";
echo "<script type='text/javascript' src='scripts/bootstrap.js'></script>";
echo"<link rel='stylesheet' type='text/css' href='css/style.css'>";
include "scripts/show.php";
echo" <title>Gallery Display</title></head><body>";
echo "<header>";
echo "<h1>The Ultimate Gallery Compiler</h1>";
echo "<div id='menu'><a class='head' href='index.html'>Upload Photo</a>&nbsp;&nbsp;<a class='head' href='gallery.html'>Browse Gallery</a></div>";
echo "</header>";
echo "<div id='content'>";
echo "<h2>Browse Gallery</h2>";
$subfolder = $_POST["category"];
if ($subfolder == "0"){
    echo("Please <a href='gallery.html'>go back</a> and select a category");
    echo "</div><br><br>";
    echo "<footer>";
    echo "<p class='foot'>&copy; Copyright 2015-2016 MMA2 Rachel Gallen, Ysabel Pheifer and Rebecca Merrigan.</p>"; 
    echo "</footer>";
    exit();
}
$countcontents = file_get_contents("categories.txt"); //read file to get count
$countarray = explode('*', $countcontents); //get count of each category into an array
$categories = array("fashion", "music", "sports", "technology", "animals", "health", "other");

//output title according to if the gallery has images in it or not
for($i=0; $i< count($countarray); $i++)
{
    if ($subfolder == $categories[$i]){
        if (intval($countarray[$i]) == 0) {
             echo "<h3>No images have been uploaded for the " .$subfolder. " category yet</h3>";
        }
        else
        {
            echo "<h3>Here are the images for the " .$subfolder. " category</h3>"; 
            echo "<p>There are ".$countarray[$i]." photos in this category</p><br>";
        }
    }
}
$folder = "images/".$subfolder."/";
// Open the appropriate subfolder, and display its contents.
// http://php.net/manual/en/function.opendir.php
// also referenced https://www.youtube.com/watch?v=nGLi4ykt__0
if ($dir = opendir($folder)) {
    $images = array();
    while (false !== ($file = readdir($dir))) {
        if ($file != "." && $file != "..") {
            $images[] = $file; 
        }
    }
    closedir($dir);
}
echo '<div id="slider">';
echo "<ul id='slides'>";
foreach($images as $image) {
    echo '<li class="slide"><img src="';
    echo $folder.$image;
    echo '" alt=""/></img></li>';
}
echo "</ul>";
echo '</div>';
echo "<p>&nbsp</p><a href='gallery.html'>Reselect</a>";
echo "</div>";
echo "<footer>
<p class='foot'>&copy; Copyright 2015-2016 MMA2 Rachel Gallen, Ysabel Pheifer and Rebecca Merrigan.</p> 
</footer>";
echo "</body></html>";
?>

任何帮助都将不胜感激！

顺便说一下，javascript是

//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);
  });
}
);

您的页面中没有包含jQuery，您在脚本中使用了jQuery，但根本没有加载它。

找到这些东西的一个好方法是使用开发者栏，在使用chrome时按F12，然后在网络上你可以看到加载了哪些文件，如果有任何javascript错误，你可以在控制台中看到。
