大家好，谢谢大家抽出时间。我的问题是关于。
我正试图循环浏览我文件夹中的图像以及数据库中的帖子，最终结果如下：
帖子1
图像1后2
图像2后3
图像3
目前我得到的结果是：
帖子1
图像1张贴1
图像2帖子1
图像1帖子2
图像1后2
图像2后2
图像3
我不想要这个结果。
以下是我的代码：
$post_info = get_posts();
foreach ($post_info as $info){
$photos = glob('design/img/*');
foreach($photos as $photo) {
echo " <a href='feed.php?pid=".$info['post_id']." ' >
<div style='background:#FFF5C3'> <br> <h2> ".$info['person_mentioned']." </h2>
<h3 style='color: black'> ".$info['body']." </h3> </div> </a>";
echo " <img src='{$photo}' width='285px' height='200px' style='border: 5px solid black'>";
}
}
谢谢你抽出时间。
试试这个（减去潜在的语言细节，因为我实际上并没有运行来检查这个代码）。。它基本上是一个常规的for循环，而不是foreach。
$post_info = get_posts();
$photos = glob('design/img/*');
if (count($post_info) === count($photos)) { // According to your requirement, the counts would be the same
$count = count($post_info);
for ($i = 0; $i < $count; $i++) {
$info = $post_info[$i];
$photo = $photos[$i];
echo " <a href='feed.php?pid=".$info['post_id']." ' > <div style='background:#FFF5C3'> <br> <h2> ".$info['person_mentioned']." </h2>
<h3 style='color: black'> ".$info['body']." </h3> </div> </a>";
echo " <img src='{$photo}' width='285px' height='200px' style='border: 5px solid black'>";
}
}
希望能有所帮助：）
从get_posts()获取图像详细信息并删除内部foreach循环可能会解决您的问题。
注意：将$info['something_like_post_image']替换为您的图像字段
$post_info = get_posts();
foreach ($post_info as $info) {
//$photos = glob('design/img/*');
//foreach ($photos as $photo) {
echo " <a href='feed.php?pid=" . $info['post_id'] . " ' >
<div style='background:#FFF5C3'> <br> <h2> " . $info['person_mentioned'] . " </h2>
<h3 style='color: black'> " . $info['body'] . " </h3> </div> </a>";
echo " <img src='" . $info['something_like_post_image'] . "' width='285px' height='200px' style='border: 5px solid black'>";
//}
}

/*
* If your images have any naming convention like
* imageFileName = "image_{POST_ID}.jpg"
* then you can use below code (NO DATABASE ENTRY REQUIRED)
* (ie, For post #1 image file would be "image_1.jpg";
* and for post #2 image file would be "image_2.jpg")
*/
$post_info = get_posts();
foreach ($post_info as $info) {
//filename = image_1.jpg or image_2.jpg or...
$photoFileName = 'design/img/' . 'image_' . $info['post_id'] . '.jpg';
if (file_exists($photoFileName)) {
echo " <a href='feed.php?pid=" . $info['post_id'] . " ' >
<div style='background:#FFF5C3'> <br> <h2> " . $info['person_mentioned'] . " </h2>
<h3 style='color: black'> " . $info['body'] . " </h3> </div> </a>";
echo " <img src='" . $photoFileName . "' width='285px' height='200px' style='border: 5px solid black'>";
}
}
注意：你应该根据你的独特形象与每个帖子保持联系；否则，你将无法在你的帖子中获得独特的图片，同时列出。签出以下选项以处理这种情况
- 您可以将图片名称保存在数据库中（对于每个帖子，您可以直接从数据库中获取图片名称）
- 为您的图像使用命名约定（对于帖子#1，使用唯一的图像名称（比如image_1，对于帖子#2 image_2等）
更新-2
如果你正在寻找一个循环通过图像（没有任何条件），使用以下代码
/*
* If you are looking for a solution that cycles each images
* along with each post, try this one
*/
$post_info = get_posts();
$photos = glob('design/img/*');
$numPhotos = count($photos) + 1;
//assuming your post# starts with 1
$imageId = 1;
foreach ($post_info as $info) {
//cycling
if ($imageId % $numPhotos === 0) {
$imageId = 1;
}
$photoFileName = 'design/img/' . 'image_' . $imageId++ . '.jpg';
//no need of this checking, since you are cycling
//if (!file_exists($photoFileName)) {
// $photoFileName = 'path/to/default/image.jpg';
//}
echo " <a href='feed.php?pid=" . $info['post_id'] . " ' >
<div style='background:#FFF5C3'> <br> <h2> " . $info['person_mentioned'] . " </h2>
<h3 style='color: black'> " . $info['body'] . " </h3> </div> </a>";
echo " <img src='" . $photoFileName . "' width='285px' height='200px' style='border: 5px solid black'>";
