@victorhuayhuapuma1505 ¡Hola! Enviar imágenes a través de WhatsApp usando JavaScript directamente desde un formulario HTML puede ser un poco complicado, ya que WhatsApp no permite el envío de archivos multimedia directamente a través de su API. Sin embargo, puedes usar la API de WhatsApp Business para enviar imágenes, pero necesitarás configurar un servidor backend para manejar la autenticación y el envío de mensajes. Si estás interesado en una solución más sencilla, te recomendaría subir las imágenes a un servicio de alojamiento (como Imgur) y luego enviar el enlace de la imagen a través de WhatsApp usando el mismo método que mostré en el video. ¡Espero que esto te ayude! Si tienes más preguntas, no dudes en preguntar. 😊
@RoniKarmakar-sk9vm Hi there! Good question. The reason for leaving a blank in the first place is to handle the AUTO_INCREMENT feature in MySQL. Typically, this blank corresponds to the id column, which is set to auto-increment. When you use an AUTO_INCREMENT column, you don't need to specify a value for it in your INSERT statement; MySQL will automatically generate a unique value for it.
@checktheq7915 That warning usually happens when there's no result set to fetch from. Make sure your query returns results before using mysqli_fetch_assoc. Check your query and connection first. If you still face issues, let me know! 😊
@chouaibechouaib10 Yes, you need to make localhost secured (https) for the camera to work because browsers require HTTPS for accessing the camera. You can use a self-signed certificate for local development.
Hi @SCHOOL_BROTHER001! Thanks for the enthusiasm! I'm glad you enjoyed the project. I'll definitely make more projects like this in JavaScript. Stay tuned, and thank you for your support! ❤❤
Hi @tannukumari2680, To store the user ID from login in a session, you should use the $_SESSION superglobal correctly. Here's the correct syntax: session_start(); // Start the session at the beginning of your PHP script $user_id = $_SESSION['user_id']; // Retrieve the user ID from the session Make sure you have session_start() at the top of all your PHP scripts where you want to access session variables.
Problem is solved but while clicking like button it's not working data like postid userid are showing in the inspect but when the button is clicked then it's not working
Bro you are making the server to engage with the database all the time. Other transactions will get into deadlock and fail. Not recommended for even beginners.
Hi @prabhakaranj1218, Thank you for your feedback! 🙏 You're right; constant server-database engagement can lead to performance issues and potential deadlocks. ⚠️ For those looking to implement a more robust solution, considering asynchronous requests and database optimization techniques is crucial. 🔄 I'll make sure to highlight these considerations in future videos. Appreciate your insight! 👍
@@DavidGTech The way you have explained is pretty inspiring. You showed the easiest way to achieve this. Anyways this one I have implemented on a signal from the server. Thanks for that😉
Thank you so much for your kind words @prabhakaranj1218! 😊 I'm glad to hear you found the explanation inspiring and easy to follow. It's great to know you've implemented it successfully on a server signal. Keep up the good work! 😉👍
Hi, I want to make a website where I want such a feature like, customer will be able to select product and directly sent to my what's app so that I can get their number and order details. Is it possible?
Hi @ibrahimhossen6549, Absolutely, it's possible! 🌟 You can create a website where customers select products and their order details are sent directly to your WhatsApp. 📱 This can be done using JavaScript to capture the form data and then use the WhatsApp API to send the message. I'll consider making a detailed tutorial on this. Stay tuned! 👍
Hi I have the problem with UserID. My emailJS dashboard do not have the same option as you it only provide the API public key and not the UserID so when I try to put the API key in the UserID there is an error that UserID cannot be found how can I resovle this
Hi @longoquang7861, Thanks for reaching out! 😊 It sounds like there might have been some changes to the EmailJS dashboard. If you only have the API public key, try using that in place of the UserID. If the issue persists, I recommend checking the EmailJS documentation or contacting their support for the latest updates. I'll look into this as well and update the tutorial if needed. Hope this helps! 👍
Hi @TechHaven_, Thanks for your comment! 😊 It sounds like there might be a small typo causing the issue. Double-check your code for any misspelled variables or function names. Sometimes, even a small error can cause problems. If you're still having trouble, feel free to share the specific part you're stuck on, and I'd be happy to help you troubleshoot it! 👍
