502 bad gateway error on some insert queries

I’m getting 502 error on my some insert queries, data is inserting into table but throwing an 502 error

Could you please fill in the topic template so we have a bit more than a vague description and a status code?


Sorry for late response,

Php code

 if(!isset($_COOKIE["alp_user_login"]) && empty($_COOKIE["alp_user_login"]))  header('Location: ./login'); else
 require 'app/classes/assets.php';$assets = new assets();$row = $assets->getLogin_credentials();
    $conn = $assets->conn();
    $subject = strip_tags(htmlspecialchars($conn->real_escape_string(str_replace("  ", " ", trim($_POST["subject"])))));
    $email = $row["user_email"];
    $form_by = $row["user_name"];
    $class = strip_tags(htmlspecialchars($conn->real_escape_string($_POST["class"])));
    $date = strip_tags(htmlspecialchars($conn->real_escape_string($_POST["date"])));
    $mm = strip_tags(htmlspecialchars($conn->real_escape_string($_POST["mm"])));
    $visible = strip_tags(htmlspecialchars($conn->real_escape_string($_POST["visible"])));
    $hide = strip_tags(htmlspecialchars($conn->real_escape_string($_POST["hide"])));
    $data = strip_tags(htmlspecialchars($conn->real_escape_string(str_replace("  ", " ", trim($_POST["form_url"])))));

    # print_r($data);
    $msg = "";
    $unique_id = "alp-form-".$subject."-".$class."-".$date;
    $formId=$assets->randomPassword(16, 1, "lower_case,upper_case,numbers");
    $form_id = $formId[0];
    echo $form_id."<br>".$subject."<br>".$class."<br>".$mm."<br>".$visible."<br>".$hide."<br>".$data."<br>".$form_by;
    $true = 1;
    $stmt = $conn->prepare("INSERT INTO alp_forms(form_id, subject, class, mm, visible_time, hide_time, form_by, user_email, isGoogle_form, g_url) VALUES(?,?,?,?,?,?,?,?,?,?)");
    $stmt->bind_param("ssssssssis", $form_id, $subject, $class, $mm, $visible, $hide, $form_by, $email, $true, $data);
    $api = "abcd123*#=+$";
    $url = "https://forms.alapdorl.xyz/public/t?v=".$form_id;
    $json = json_decode($assets->curl_get_contents("https://cutt.ly/api/api.php?key=".$api."&short=".$url), true);
    # echo $url."<br>";
    # $msg = 'Your form has been imported successfully.<br>And here your form url <a href="'.$json["url"]["shortLink"].'">'.$json["url"]["shortLink"].'</a>';
    # echo $json["url"]["shortLink"];
    header('Location: ./dashboard?url='.$json["url"]["shortlink"]);
    } else{
        $msg = "Sorry there was an internal error occured during processing, please try again later. Or <a href='/#contact-section'>Contact us</a>.";
    echo $msg."<br>";

Please remember that this is a publicly accessible forum, so never share any sensitive data (like passwords) here. I just reset your account password.

As for your code, maybe the cutt.ly API is slow and preventing the successful execution of your code? Does the API call have a timeout set?


Can you try instead of <? use <?php

@HaydenANG Yess

First thank you so much for step and I’m really Sorry that I mistakenly shared my password, and I’m changing api from Cutt.ly to another.

@Admin Sorry for disturbing you can you please suggest me good URL shortener api

I personally use rebrand.ly
