Five years ago, I created JSON Table Editor. Recently I have the time to revisit the project and do some minor bug fixes and enhancements.

  1. Array editing.
    In previous version, loading an array of string will give you a table of characters. This is embarrassingly wrong.

    The updated version has no more of this problem.

  2. Improvements on multi-level object editing.
    I changed the button title from ‘Save to Upper Level’ to ‘Finish Editing’, which is more appropriate. I also make the window closed when you click ‘Finish Editing’ button. I also show the updated JSON so we can notice the changes.

    The changes also propagated all the way to the top. In previous version, on each child-window we need to click the ‘Save to Upper Level’ button.

  3. Limiting the proxy
    The proxy in the previous version is just a dumb proxy. It fetches any url requested and dump whatever content. I see a potential misuse here. So I limit the proxy to only fetch JSON, CSV and raw/text content.

    	$qUrl = $_REQUEST["q"];
    	// create a new cURL resource
    	$ch = curl_init();
    	// set the URL
    	curl_setopt($ch, CURLOPT_URL, $qUrl);
    	// get only the Head
    	curl_setopt($ch, CURLOPT_NOBODY, true);
    	// curl_exec return value instead of directly to out
    	curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    	// do the request
    	$res = curl_exec($ch);
    	// check the content type
    	$contentType = curl_getinfo ($ch, CURLINFO_CONTENT_TYPE);
    	//only accept json, csv
    	if (strpos($contentType,'/json')!== false || strpos($contentType, '/csv')!== false || strpos($contentType, 'text/plain')!== false)
    		// ... SNIP ...
    		// Normal CURL processing
    	else {
    		//error_log('Not JSON');
    		echo "Invalid resource. We only retrieve JSON/CSV/text resource. The requested URL returned ".$contentType;
  4. That’s all, folks! Looking forward to hear your thoughts. Cheers!
