使用 PHP 將圖像和圖像名稱填充到此幻燈片代碼中

Question

我正在努力創建一個 php 畫廊幻燈片，希望有人可以推薦如何做這部分..

下面的代碼取自 w3schools 並且運行良好，但是我想使用存儲在文件夾中的圖像來填充圖像標簽的 src。 我有一個裝滿圖像的文件夾，我想將它們拉入幻燈片並使用每個圖像文件的名稱作為標題。

例如...

而不是這個：

  <div class="mySlides">
    <div class="numbertext">4 / 6</div>
      <img src="img_lights_wide.jpg" style="width:100%">
  </div>

做這個：

<div class="mySlides">
   <div class="numbertext">4 / 6</div>
   <img src="**CODE TO PULL EACH IMAGE FROM A LOCAL FOLDER eg. 1.jpg then 2.jpg then 3.jpg**" style="width:100%">
   <h2> **Name of the slide taken from the file name e.g.Apples, Bananas, Oranges**</h2>
</div>

記者：

var slideIndex = 1;
showSlides(slideIndex);

// Next/previous controls
function plusSlides(n) {
  showSlides(slideIndex += n);
}

// Thumbnail image controls

  var dots = document.getElementsByClassName("demo");

  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";

你可以試試：

$directory = "/images";
$images = glob($directory . "/*.jpg");
$image_list_1 = "";
$i = 0

foreach($images as $image)
{
    $image_list_1 .= '<div class="mySlides fade"><div class="numbertext">'.$i.' / '.count($images).'</div><img src="'.$image.'" style="width:100%"><div class="text">Caption Text</div></div>';
}

 <!-- Slideshow container -->
<div class="slideshow-container">

  <!-- Full-width images with number and caption text -->
  <?=$image_list_1?>

  <!-- Next and previous buttons -->
  <a class="prev" onclick="plusSlides(-1)">&#10094;</a>
  <a class="next" onclick="plusSlides(1)">&#10095;</a>
</div>
<br>

<!-- The dots/circles -->
<div style="text-align:center">
<?php
foreach ($images as $key => $value) { 
    echo '<span class="dot" onclick="currentSlide('.($key+1).')"></span>'; 
    echo "\n";
}   
?>
</div>
