How to solve the problem of content loss when PHP uploads graphic messages with multiple pictures to the WeChat public platform?
1. Question: Upload an article in wordpress as permanent material to WeChat: When there is only one picture in the article, it can be uploaded normally, and when viewing this material on the WeChat public platform, both text content and pictures can be Displayed in full. Add another picture to the article (when the article picture is larger than 1), when viewing this material in the WeChat background, it is found that the article is incomplete: all content starting from the first picture is lost. Additional instructions: (1) I wrote a plug-in to upload WordPress articles to the WeChat material library. Main process: curl grabs the pictures in the article and uploads them to the WeChat material library, obtains the URL and then replaces the picture src in the wordpress article accordingly. Then construct a json string of image and text message and upload it to WeChat. (2) No styles are added to the wordpress article, only
3. Error message: WeChat did not return an error message. 4, Screenshot: None. 5, other references: I saw tilun_099 encountered similar problems on CSDN: http://bbs.csdn.net/topics/39.... tilun_099's question is: "When uploading multi-image and text materials, if the content of the content is plain text, the upload can be successful, the media_id can be obtained, and then through the group sending interface, the mobile phone can correctly obtain the multi-image and text information. But if the content in the content When tags containing HTML, such as
,
, etc., although the media_id can be obtained after uploading, after mass sending, the mobile phone will get a single image and text, and this single image and text has a picture, title, and link. , that is, the content is empty. " tilun_099's final solution to his problem: "Although no one answered, I finally solved it. If the content contains html tags, it needs to be corrected. Escape the content. If it contains content with a "" sign like style="..", you need to pay more attention.
<code>foreach ($news as &$item){
foreach ($item as $k=>$v){
if($k =='content'){
$item[$k] = urlencode(htmlspecialchars(str_replace("\"","'",$v)));
}else{
$item[$k] = urlencode($v);
}
}
}</code>
It is necessary to convert the "" quotes in the html into single quotes first, and then convert them into html entities, so that the tags will not be affected when urlencoding is performed.
Before uploading, urldecode the content and convert the html entities into html tags, and it will be OK. Tested! ”
The problem he and I encountered is somewhat similar, but not exactly the same. I constructed json directly.

You can embed PHP code into HTML files, but make sure that the file has an extension of .php so that the server can parse it correctly. Use standard tags to wrap PHP code, insert dynamic content anywhere in HTML. In addition, you can switch PHP and HTML multiple times in the same file to realize dynamic functions such as conditional rendering. Be sure to pay attention to the server configuration and syntax correctness to avoid problems caused by short labels, quotation mark errors or omitted end labels.
The key to writing clean and easy-to-maintain PHP code lies in clear naming, following standards, reasonable structure, making good use of comments and testability. 1. Use clear variables, functions and class names, such as $userData and calculateTotalPrice(); 2. Follow the PSR-12 standard unified code style; 3. Split the code structure according to responsibilities, and organize it using MVC or Laravel-style catalogs; 4. Avoid noodles-style code and split the logic into small functions with a single responsibility; 5. Add comments at key points and write interface documents to clarify parameters, return values ??and exceptions; 6. Improve testability, adopt dependency injection, reduce global state and static methods. These practices improve code quality, collaboration efficiency and post-maintenance ease.
