How to Access Dynamic JSON Keys in Nested JSON Results
Problem:
You have a nested JSON result with dynamic keys, such as "141", "8911", etc. You need to access the content of these dynamic keys, such as the "count" or "more_description" values.
JSON:
{ "status": "OK", "search_result": [ { "product": "abc", "id": "1132", "question_mark": { "141": { "count": "141", "more_description": "this is abc", "seq": "2" }, "8911": { "count": "8911", "more_desc": "this is cup", "seq": "1" } }, "name": "some name", "description": "This is some product" }, { "product": "XYZ", "id": "1129", "question_mark": { "379": { "count": "379", "more_desc": "this is xyz", "seq": "5" }, "845": { "count": "845", "more_desc": "this is table", "seq": "6" }, "12383": { "count": "12383", "more_desc": "Jumbo", "seq": "4" }, "257258": { "count": "257258", "more_desc": "large", "seq": "1" } }, "name": "some other name", "description": "this is some other product" } ] }
Solution:
To access the content of dynamic JSON keys, follow these steps:
- Obtain the JSONObject representing the "question_mark" object using JSONObject.getJSONObject("question_mark").
- Use JSONObject.keys() to get an Iterator of the dynamic keys.
- Iterate through the keys using the Iterator.hasNext() and Iterator.next() methods.
- For each dynamic key, use JSONObject.getJSONObject(String key) to get the corresponding JSONObject representing the dynamic value.
- Access the desired values from the JSONObject representing the dynamic value.
Java Code:
JSONObject questionMark = searchResult.getJSONObject("question_mark"); Iterator keys = questionMark.keys(); while(keys.hasNext()) { String currentDynamicKey = (String)keys.next(); JSONObject currentDynamicValue = questionMark.getJSONObject(currentDynamicKey); // Access and manipulate the content of the currentDynamicValue... }

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
