[英]Get intro image by ID from database (joomla)
I am trying to read the intro image from a joomla database. 我正在尝试从joomla数据库读取简介图片。 I have a list of products, that each need to show the intro image that matches the ID of the product.
我有一个产品列表,每个产品都需要显示与产品ID匹配的介绍图片。
// content
$content = "SELECT * FROM `snm_content` WHERE catid = 13";
$contentcon = $conn->query($content);
$contentcr = array();
while ($contentcr[] = $contentcon->fetch_array());
$img = $contentcr[0]['images'];
$plaatje = explode('/', $img);
$plaatje = explode('"', $plaatje[2]);
$plaatje = $plaatje[0];
$img = preg_replace('/[^a-zA-Z0-9\']/', '_', $img);
$img = explode('___', $img);
$img = $img[1];
Then in a foreach I put the following code: 然后在foreach中,我输入以下代码:
<img src="cms/images/website/'.$plaatje.'" alt="" class="company_logo">
This shows the same image for every product though. 但是,每个产品都显示相同的图像。
I read something about json_decode to get the image path from the database field. 我读了一些有关json_decode的信息,以从数据库字段获取图像路径。
How can I get the correct image for every product? 如何获得每种产品的正确图像?
The following code prints the correct array: 以下代码显示正确的数组:
print_r($content['images']);
Example of a field in the database with all the possible images (intro, full etc) 数据库中包含所有可能图像(简介,完整等)的字段示例
{"image_intro":"images\/website\/Airco_blog.jpg","float_intro":"","image_intro_alt":"","image_intro_caption":"","image_fulltext":"","float_fulltext":"","image_fulltext_alt":"","image_fulltext_caption":""}
I guess this will work for you : 我想这将为您工作:
$article_images = $content['images'] // Get image parameters of the article
$pictures = json_decode($article_images); // Split the parameters apart
echo "<img src='" . $pictures->{'image_intro'} . "' alt='" . $pictures->{'image_intro_alt'} . "'>"; // get the intro image
// Edited your post to fix the image tag. //编辑您的信息以修复图片标签。
