Wordpress plugin Woody Snippets: MYSQL prepared statement interferes with JavaScript execution

Other Questions Wordpress

I’m experiencing an issue with a MYSQL prepared statement on my Wordpress site that uses the Woody Snippets plugin to add PHP, HTML, JavaScript, and CSS code. When I include a specific line in my PHP function, it disrupts the page display.

Here’s a revised version of the function:

function fetchCountyData() {
  $query = "SELECT id, county_name FROM wp_counties WHERE state_id=? ORDER BY county_name ASC";
  $stmt = $link->prepare($query);
  $stmt->bind_param("i", $stateId);
  $stmt->execute();
  $resultData = $stmt->get_result();
  return $resultData;
}

When the get_result() line is active, my JavaScript appears to be ignored, affecting the display of my page. However, commenting out that line fixes the display.

I’m curious: how can this single line of PHP impact my JavaScript? Is this a known issue with the Woody Snippets plugin, or is there another explanation? Your insights would be greatly appreciated.

As someone who’s wrestled with similar issues, I can offer some insights. The get_result() function isn’t likely the direct culprit, but it might be triggering a chain of events that’s messing with your JavaScript.

First, check if the data you’re fetching contains any special characters or HTML. If it does, it could be breaking your page structure when output directly. Try using htmlspecialchars() on your data before displaying it.

Also, the Woody Snippets plugin might be interfering. Some plugins modify output in ways that can break scripts. Try temporarily deactivating it to see if the problem persists.

Another thing to consider: are you outputting data directly to the page? If so, try capturing it in a variable first, then echo it after all database operations are done. This can prevent partial output from breaking your JS.

Lastly, make sure your JavaScript is loading at the right time. If it’s trying to manipulate elements before they’re ready, it could fail silently. Consider moving your script to the footer or wrapping it in a DOMContentLoaded event listener.

Hope this helps you track down the issue!

Having dealt with similar issues, I can say it’s likely not the get_result() itself causing problems, but rather how the data is being handled afterwards. Make sure you’re properly escaping any output from the database before it hits your HTML. Also, check if the Woody Snippets plugin is modifying your output in any way - some plugins can interfere with content rendering. If you’re outputting directly to the page, try capturing the output in a variable first, then echoing it after all database operations are complete. This can help prevent partial output from breaking your JavaScript. Lastly, ensure your JavaScript is loaded in the footer or wrapped in a DOMContentLoaded event to avoid execution before the DOM is fully loaded.

hey swiftcoder42, sounds like a tricky issue! have you tried wrapping your js code in a DOMContentLoaded event listener? Sometimes php output can mess with script execution if it’s not loaded in the right order. might be worth a shot. also check if the plugin is outputting any extra stuff that could be breaking your js. good luck!
