I want to send my data to database with about 3 to 4 images. Also fetch it with RESR API

SlimPrince · March 10, 2023, 1:16am

I’ve almost completed this Android App project before I realized that I need to upload the products with pictures. Subscribers will have to register the product with image and I’ll have to upload it using REST API in android studio.
I just started using Slim Framework and it is just the best for me and I want to learn more about it. I’m just a beginner.

Below is my code without images and please I need help to learn how to add images to it.
Below is my “DbOperationsProperties.php”

<?php

class PropertyDetails
{
    private $con;

    function __construct()
    {
        require_once dirname(__FILE__) . '/DbConnect.php';
        $db = new DbConnect;
        $this->con = $db->connect();
    }

    // --------------------------------------------------------------------

    public function createUserPrDt(
        $personalIdCode,
        $propertyType,
        $propertyLocation,
        $plotNumber,
        $propertySize,
        $propertyTitle,
        $propertyPurpose,
        $propertyNetPrice,
        $propertyDescription
    ) {
        if (!$this->isPlotNumberExist($plotNumber)) {
            $stmt = $this->con->prepare(

To add image upload functionality to your Android app using Slim Framework, you need to modify the API endpoints to handle file uploads.

Please read here: Uploaded Files

You may also need to modify the database to store the filenames of the uploaded images, and you may also modify the Android app to upload images along with the other data. To retrieve the images, you could add an endpoint that returns the images according to a certain user-specific parameter.
