Http error 405 php

I’m getting a HTTP Error 405 when trying to post a small form using PHP. Codes are given below. How can I solve this one?

  <div class="quiz-section">
            <form action="quiz.php" method="post">
                #################
            <input type="submit" class="btn blue" name="submitQuiz" value="Submit" />
        </form>
   </div>





<?php
    if (isset($_POST['submitQuiz'])) {
        if(isset($_POST['quest1'])&&isset($_POST['quest2'])&&isset($_POST['quest3']))
        {
            if(($_POST['guestName']!="")&&($_POST['guestEmail']!="")){

                $to      = 'a######@yahoo.com';
                $subject = 'Quiz Answer Submission';
                $message = "Submited by: ".$_POST['guestName']." From email: ".$_POST['guestEmail']." Answers are: ".$_POST['quest1'].", ".$_POST['quest2'].", ".$_POST['quest3'];

                $headers = 'From: j#####@live.in' . "rn" .
                    'Reply-To: '.$_POST["guestEmail"] . "rn" .
                    'X-Mailer: PHP/' . phpversion();

                mail($to, $subject, $message, $headers);
                echo "Thanks for your submission. We successfully received your answers. Stay tuned.";
                //header("Location: index.html#quiz-questions?status=Success");
            }
            else{
                    echo "Please go back and answer all quiz questions";
            }
        }
        else{
                echo "Please fill all the fields and answer to all questions";
                //header("Location: index.html#quiz-questions?status=Error");
        }
    }
?>

The Error message is:

The page cannot be displayed

The page you are looking for cannot be displayed because an invalid method (HTTP verb) was used to attempt access.
Please try the following:

Contact the Web site administrator if you believe that this request should be allowed.
Make sure that the Web site address displayed in the address bar of your browser is spelled and formatted correctly.
HTTP Error 405 - The HTTP verb used to access this page is not allowed.
Internet Information Services (IIS)

Technical Information (for support personnel)

Go to Microsoft Product Support Services and perform a title search for the words HTTP and 405.
Open IIS Help, which is accessible in IIS Manager (inetmgr), and search for topics titled Setting Application Mappings, Securing Your Site with Web Site Permissions, and About Custom Error Messages.

In this article, we will show you how to send a “405 Method Not Allowed” header using PHP.

The “405” status allows us to tell a client it is using an incorrect HTTP method.

This is an important header to have in your “toolbox” if you want to restrict certain PHP scripts to POST, PUT, or GET requests.

For example, let’s say that we want to restrict a PHP script to POST requests only.

//An array of HTTP methods that
//we want to allow.
$allowedMethods = array(
    'POST'
);

//The current request type.
$requestMethod = strtoupper($_SERVER['REQUEST_METHOD']);


//If the request method isn't in our
//list of allowed methods.
if(!in_array($requestMethod, $allowedMethods)){
    //Send a 405 Method Not Allowed header.
    header($_SERVER["SERVER_PROTOCOL"]." 405 Method Not Allowed", true, 405);
    //Halt the script's execution.
    exit;
}

//This will only be printed out if a
//POST request is used.
echo 'Hello world!';

In the PHP code above:

1. We create an array of HTTP methods that we want to allow. In this case, we only want to allow POST requests. If we also want to allow PUT, HEAD and OPTIONS requests, then we can add them to the array as well.
2. We retrieve the current request type by accessing the $_SERVER[‘REQUEST_METHOD’] variable.
3. After that, we check to see if the current request type is in our array of allowed HTTP methods.
4. If the current HTTP method is not present in our $allowedMethods array, we send a “405 Method Not Allowed” response to the client. We do this by using PHP’s header function.
5. Finally, we terminate the script.

If you attempt to navigate to this PHP script in your browser, you will see the following:

This is because your browser sent a GET request to the page when the PHP script only accepts POST requests.

Furthermore, if you inspect the response headers for the request in your browser’s developer tools, you will see something like this:

As you can see, our PHP script has returned a “405 Method Not Allowed” status code to the browser.

Using the http_response_code function to send a 405 error.

If you are using PHP version 5.4.0 or above, then you can use the http_response_code function.

This function is a little more concise:

//Send a 405 Method Not Allowed header using http_response_code.
http_response_code(405);
//Kill the script.
exit;

In the example above, we simply replaced the header function with the http_response_code function and passed in 405 as the $response_code parameter.

On the other hand, a 405 Method Not Allowed error means that the requested resource is valid and does exist; however, the HTTP request method used by the browser is not received by your web server.

405 Method Not Allowed Error Variations

You will see an HTTP 405 method not allowed error in the form we have discussed above, different browsers, web servers, and operations systems have their unique ways to present in varied ways. The actual cause of the issue also tends to differ from server to server, this will also change the way the method not allowed 405 error appears.

This is because it lets you know that something has gone wrong, but they will not tell you about the reason behind the issue. Generally, you will have to do all the research to find the root cause and repair it, if possible.

What Causes Http Error 405 Not allowed?

Let us put the definition of 405 Method Not Allowed error into perspective – HTTP delineate set of methods that bespeak viable actions that can be carried out on the webserver that is being contacted. For instance, this comprises of the following methods –

• GET – Obtain information related to a described URL resource.
• HEAD – Get header details related to a URL resource.
• POST – Send data to the web server, for instance – form data.
• PUT – Replace the available data for a specific URL along with the new data provided by the client.
• DELETE – Delete the data from the specified URL.
• CONNECT – Founded a channel to the server as identified by the target resource.
• OPTIONS – Explains the available options for communication for the described target audience.
• TRACE – This method will activate a loop-back test en route to the target resource.
• PATCH – Executes partial alterations to a resource.

Entirely depending on the goal of the web server, its administrator will organize it to adopt particular methods or ignore others. For instance – if a particular website lacks interactive content, it hardly makes any sense to let the POST method on the web server. In case, this method is not permitted and a client has contacted the server using a POST request, there will be an error 405 method not allowed post, notifying the browser that there is no permission for the method.

Diagnosing the Error 405 Method Not Allowed Message

• The reason behind the appearance of the error is the misconfiguration of the web server or the software parts that are tasked with acting on a particular URL resource.
• The hosting provider used by the website administrator has not allowed the HTTP method. This can be commonly seen with the POST method – Keeping in mind the security reasons, Some WordPress hosting providers have blocked this particular method while accessing HTML documents.
• The administrator of the website has prohibited the HTTP method used by the user agent – this is also done keeping in mind the security element.

Generally, this is taken care of by the web server. However, if the method is not enabled, a pre-connected Proxy or HTTP handler can also be blamed for the issue.

Input Correct Url to Avoid Http Status 405 Method Not Allowed

One of the common causes of a 405 Method Not Allowed error is to input the wrong URL. Nowadays, most of the web servers incorporate tight security measures and they don’t allow access to any improper URLs to prevent the visitors from accessing the wrong pages.

There is no denying that updates come handy. With regular updates, you get to enjoy new exciting features and can help fix bugs and patch security holes. However, despite being a boon, updates can seldom cause some issues.

In case you have updated your WordPress just before the 405 Method Not Allowed error occurs, the new code might be the root cause of the issue. This also applies to the newly upgraded themes or extensions.

If you firmly believe that an update is the main culprit, then you may want to return to the previous version of WordPress. Like we have already discussed, don’t forget to have a full website backup before you ahead with this. , It’s worth reverting back to the previous version of WordPress.

This can be done manually as well, but using a plugin will easily help you roll back WordPress updates. You have a plethora of options at your disposal, but WP Downgrade is effective. With the help of this plugin, you are going to automate the process and you will be able to carry out things without making any error.

Uninstall New Extensions, Modules, Plugins and Themes

Plugins are considered one of the key parts of any WordPress website. With the help of these plugins, you can add a plethora of features and above all, you can automate complex processes without any hassle. If we talk about themes, they are equally important. Without them, you will be spending most of your time doing intricate coding to create an appealing website.

Alas, just as you face issues with software updates, these extensions may also create issues. This is because when you add functionality at any level, it completely changes the way it operates. You may face an issue with the plugin or theme you are using, or any extension may cause a conflict with another part of your website. In such case, you should use Multi-purpose themes. Multipurpose WordPress themes are flexible WordPress templates that can be used to create almost any kind of website imaginable.

Consequently, if you choose to uninstall particular plugins or themes, you may be able to fix the issue. To start this process, you need to go to the Plugins section of the WordPress dashboard. This page will have a detailed list of all the installed plugins –

This is where you can start uninstalling the plugins one by one. When you are done uninstalling the plugins, check whether the issue has been resolved. You have to wait for a while as this process takes some time to complete, but you will get to know as to which plugin was causing the issue.

Now, you can repeat the same process with your active theme as well. If your theme or any of the plugin is creating the issue, you need to contact the developer, get rid of the plugin or theme, or you can look for the replacement.

Check if Unexpected Database Changes Causing Error 405 Method Not Allowed

Although you may be able to resolve any plugin or theme-related issue, you cannot be sure that the changes made by your extensions have been completely reverted. This happens with most of the WordPress plugins. Most of the time, they are given complete access to your database as you hit install.

A plugin might be able to make changes to the database records that don’t belong to it, until the developer clearly codes against it, but are alternatively managed by WordPress itself. In this case, the plugin might not be familiar with how to revert those alterations to database records, so it will pay no attention during the installation process.

Identifying the exact issue can be tricky, but if you still feel that the 405 Not Allowed error has been caused by a theme or plugin, then checking your database might help. You can find out by checking the database of your website and go through the tables and records changed by the extension. If you are still not sure, then try getting help from your developer.

Check Your Server Configuration Settings

Your website probably runs on a server that uses one of the two most popular server software options – Nginx and Apache. At the time of publication, both of these web servers make up 84% of the world’s web server software! If you can check software configuration files of your web server for any unintentional handling instructions, you may be able to find the root cause of the 405 Method Not Allowed error.

The key file will help you in making you familiar with the application your web server is using. Let us understand this with the help of an example. Let us assume that your web server is running Apache, you will find a .htaccess file within the root directory of the file system of your website.

In case, your application is on a shared host, you are possibly having a username linked with your account. If that is the case, finding the root directory will be quite easy by following the below-mentioned path –

/home/public_html/

Therefore, you will find the .htaccess file at –

/home/public_html/.htaccess

When you have successfully located .htaccess file, you need to open the file in a text editor and search for the lines that Rewrite directives. In Apache, these are a part of the mod_rewrite module. It defines a text-based pattern that will be matched against all entered URLs. In case, a user requests for a matching URL to your website, the RewriteRule will be redirecting the visitor aptly.

Let us understand this with the help of an example. Following is a RewriteRule that goes with all inbound requests to XYZ.com and retort with a 405 Method Not Allowed error.

Now, as you can see that there is a flag at the end of the rule marked R=405, it clearly affirms that response codes need to be 405. This demonstrates to the user that there is the availability of the resource; however, the specific HTTP method was unacceptable.

In case, you come across any awkward Rewrite directives in the .htaccess file having a similar instruction, make sure you provisionally comment them out with the help of # character prefix. Now, restart your web server to see if this has resolved the 405 method not allowed nginx or Apache error..

Configuration options for each different type of web server can vary dramatically, this is a list a few popular ones to give you some resources to look through, depending on what type of server your application is running on:

• Apache
• Nginx
• IIS
• Node.js
• Apache Tomcat

Check the server-side logs and Debug WordPress Issues

About every web application tends to keep some sort of server-side logs. Generally, web application logs have the complete history of all the tasks done by the software – from the database results it provides, to the pages, it has requested.

Whereas server logs are a bit different, they are linked with the actual hardware that is responsible for running the application. They will time and again provide the details of both the health and the status of all connected services, or just the server itself.

If you are looking for your WordPress server logs, connect to your website through SFTP (Secure File Transfer Protocol). There is a folder known as logs in the root directory, within this folder there are access logs along with your WordPress error logs. They look like this –

• Access.log
• Error.log

From there, you need to follow a process that is discussed in the previous point. Examine the logs and take note of anything that looks out of place. You can also refer to the codex for additional debugging details in WordPress.

Try Debugging Application Codes or Scripts

Assuming that none of the above-mentioned steps worked for you, debugging the error is your last line of resistance – that is before you seek the assistance of the developer or hosting provider. Debugging the codes and scripts is one of the effective ways through which you can find the actual cause behind 405 Method Not Allowed error.

Be sure to make a copy of the entire installation ideally, you should do this to an online or local development area, like a staging site. From there, you can start the debugging process step-by-step. Remember, this will vary on your website and its attached software.

WP_DEBUG WP_DEBUG

WP_DEBUG is a PHP constant (a permanent global variable) that can be used to trigger the “debug” mode throughout WordPress. It is assumed to be false by default and is usually set to true in the wp-config.php file on development copies of WordPress.

Note: The true and false values in the example are not surrounded by apostrophes (‘) because they are boolean (true/false) values. If you set constants to 'false', they will be interpreted as true because the quotes make it a string rather than a boolean.

It is not recommended to use WP_DEBUG or the other debug tools on live sites; they are meant for local testing and staging installs.

Wrap Up
