从数据库中将图像插入 html 表中
[英]insert image in html table from database
问题描述
I am trying to display my images in a HTML table but for some reason they just won't show up.

The images are located in a separate folder called 'images' and the image name is stored in my database as a varchar named eg, filename.jpg这些图像位于一个名为“images”的单独文件夹中，图像名称作为 varchar 存储在我的数据库中，例如 filename.jpg
In my overview page I use this as my code:在我的概述页面中，我使用它作为我的代码：
<!DOCTYPE html>
<html lang="en">
<body>
<table>
<?php
foreach ($objectname as $key) {
echo '<tr><td><img src="images/' . $key->getImage() . '"></td></tr>';
}
?>
</table>
</body>
</html>

You should first print print_r ($objectname), check if it comes with data and what its attributes are to see which one you need to occupy.你应该先打印print_r($objectname)，检查它是否带有数据以及它的属性是什么，看看你需要占用哪个。 Second the $ key->getImage() getImage () = function () you are calling a function.其次 $ key->getImage() getImage () = function () 你调用的是 function。

I think you should change the getImage() function in your html to the name of the field in the database as follows: $key->getImage() to $key->Image_field_name_in_the_database我认为您应该将 html 中的 getImage() function 更改为数据库中字段的名称，如下所示： $key->getImage()到$key->Image_field_name_in_the_database
Because the name of the image (eg: filename.jpg) is saved in a field of a table in your database.因为图像的名称（例如：filename.jpg）保存在数据库表的字段中。 Image_field_name_in_the_database will be the name of the field that contains the name of the image in the database. Image_field_name_in_the_database将是包含数据库中图像名称的字段的名称。
