上传图片并在灯箱中查看

Question

我创建了上传到灯箱图库的按钮，但是当它们上传到文件夹中时，脚本在图库中查看图像时遇到问题。这是我的演示。- http://t2.screenbg.net/2.php

<?php
   if(isset($_FILES['image'])){
      $errors = array();
      $file_name = $_FILES['image']['name'];
      $file_size = $_FILES['image']['size'];
      $file_tmp = $_FILES['image']['tmp_name'];
      $file_type = $_FILES['image']['type'];
      $file_ext = strtolower(end(explode('.', $_FILES['image']['name'])));
      
      $extensions = array("jpeg", "jpg", "png");
      
      if(in_array($file_ext, $extensions) === false){
         $errors[] = "extension not allowed, please choose a JPEG or PNG file.";
      }
      
      if($file_size > 2097152){
         $errors[] = 'File size must be exactly 2 MB';
      }
      
      if(empty($errors) == true){
         move_uploaded_file($file_tmp, "2_files/".$file_name);
         echo "Success";
      }else{
         print_r($errors);
      }
   }
?>

我希望可以添加脚本，该脚本在上传新图片时将"img src"行添加到图库。

Answer 1

要从文件夹中查看图像，请使用：

 $image = "pathtoyourimage";
 echo '<img src="'.$image.'" alt="image" height="100" />';

Answer 2

我正在尝试将每个上传的图像集成到灯箱图库中。

<h2 style="text-align:center">Lightbox</h2>
<div class="row">
  <div class="column">
    <img src="img_nature.jpg" style="width:100%" onclick="openModal();currentSlide(1)" class="hover-shadow cursor">
  </div>
  <div class="column">
    <img src="img_snow.jpg" style="width:100%" onclick="openModal();currentSlide(2)" class="hover-shadow cursor">
  </div>
  <div class="column">
    <img src="img_mountains.jpg" style="width:100%" onclick="openModal();currentSlide(3)" class="hover-shadow cursor">
  </div>
  <div class="column">
    <img src="img_lights.jpg" style="width:100%" onclick="openModal();currentSlide(4)" class="hover-shadow cursor">
  </div>
</div>
<div id="myModal" class="modal">
  <span class="close cursor" onclick="closeModal()">&times;</span>
  <div class="modal-content">
    <div class="mySlides">
      <div class="numbertext">1 / 4</div>
      <img src="img_nature_wide.jpg" style="width:100%">
    </div>
    <div class="mySlides">
      <div class="numbertext">2 / 4</div>
      <img src="img_snow_wide.jpg" style="width:100%">
    </div>
    <div class="mySlides">
      <div class="numbertext">3 / 4</div>
      <img src="img_mountains_wide.jpg" style="width:100%">
    </div>
    
    <div class="mySlides">
      <div class="numbertext">4 / 4</div>
      <img src="img_lights_wide.jpg" style="width:100%">

    <a class="prev" onclick="plusSlides(-1)">&#10094;</a>
    <a class="next" onclick="plusSlides(1)">&#10095;</a>
    <div class="caption-container">
      <p id="caption"></p>
    </div>
    <div class="column">
      <img class="demo cursor" src="img_nature_wide.jpg" style="width:100%" onclick="currentSlide(1)" alt="Nature and sunrise">

    <div class="column">
      <img class="demo cursor" src="img_snow_wide.jpg" style="width:100%" onclick="currentSlide(2)" alt="Snow">

    <div class="column">
      <img class="demo cursor" src="img_mountains_wide.jpg" style="width:100%" onclick="currentSlide(3)" alt="Mountains and fjords">
    </div>
    <div class="column">
      <img class="demo cursor" src="img_lights_wide.jpg" style="width:100%" onclick="currentSlide(4)" alt="Northern Lights">
    </div>
  </div>
</div>
<script>
function openModal() {
  document.getElementById('myModal').style.display = "block";
}
function closeModal() {
  document.getElementById('myModal').style.display = "none";
}
var slideIndex = 1;
showSlides(slideIndex);
function plusSlides(n) {
  showSlides(slideIndex += n);
}
function currentSlide(n) {
  showSlides(slideIndex = n);
}
function showSlides(n) {
  var i;
  var slides = document.getElementsByClassName("mySlides");
  var dots = document.getElementsByClassName("demo");
  var captionText = document.getElementById("caption");
  if (n > slides.length) {slideIndex = 1}
  if (n < 1) {slideIndex = slides.length}
  for (i = 0; i < slides.length; i++) {
      slides[i].style.display = "none";
  }
  for (i = 0; i < dots.length; i++) {
      dots[i].className = dots[i].className.replace(" active", "");
  }
  slides[slideIndex-1].style.display = "block";
  dots[slideIndex-1].className += " active";
  captionText.innerHTML = dots[slideIndex-1].alt;
}
</script>

这是通过回显查看上传图像的代码，但不是在灯箱画廊中查看。只想查看灯箱图库中目录 ./images 中的所有图像，问题是如何集成到其中？谢谢！

 <?php 
$dir = "images/";
if ($opendir = opendir($dir)) 
{
    while (($file = readdir($opendir)) !==FALSE)
{
    if ($file!="."&&$file!="..")
     echo "<img src='/$dir/$file'><br>";
}
} ?>
