How to Save a File from Selector to CPanel Storage for VueJS: A Step-by-Step Guide

Are you tired of struggling to save files from your VueJS application to your CPanel storage? Do you find yourself lost in a sea of code, unsure of how to bridge the gap between your frontend and backend? Fear not, dear developer! In this comprehensive guide, we’ll take you by the hand and walk you through the process of saving a file from a selector to CPanel storage, specifically tailored for VueJS applications.

What You’ll Need

Before we dive into the meat of the matter, make sure you have the following requirements met:

• A VueJS application set up and running (we’ll assume you’re using Vue 2.x or 3.x)
• A CPanel account with storage enabled (we’ll cover the CPanel side of things later)
• A basic understanding of JavaScript, VueJS, and HTML

Understanding the File Selector

Before we can save a file to CPanel, we need to understand how to access the file selector in our VueJS application. The file selector is typically an HTML input element of type “file”, which allows users to select one or multiple files from their local system.

<template>
  <input type="file" @change="handleFileChange" multiple>
</template>

In the above example, we’ve added a file input element to our VueJS template. The `@change` event listens for changes to the file input, and the `handleFileChange` method will be called whenever a file is selected.

CPanel Storage: A Quick Primer

CPanel is a popular web hosting control panel that provides a range of features, including file storage. For our purposes, we’ll focus on using the CPanel File Manager to store and retrieve files.

To access the File Manager in CPanel, follow these steps:

1. Log in to your CPanel account
2. Click on the “Files” section
3. Click on the “File Manager” icon

Once you’re in the File Manager, you’ll see a list of your files and directories. We’ll use this interface to store and retrieve files in our VueJS application.

Saving a File to CPanel Storage

Now that we have our file selector set up and a basic understanding of CPanel storage, let’s dive into the code. We’ll create a new method in our VueJS component to handle the file upload:

<script>
export default {
  methods: {
    handleFileChange(event) {
      const file = event.target.files[0];
      const formData = new FormData();
      formData.append('file', file);

      axios.post('/upload.php', formData, {
        headers: {
          'Content-Type': 'multipart/form-data'
        }
      })
      .then(response => {
        console.log(response.data);
      })
      .catch(error => {
        console.error(error);
      });
    }
  }
}
</script>

In this example, we’re using the `axios` library to send a POST request to an `upload.php` script on our server. The `formData` object contains the selected file, which is appended as a key-value pair.

On the server-side, we’ll create an `upload.php` script to handle the file upload:

<?php
  // Configuration
  $uploadDir = '/path/to/upload/directory';
  $maxFileSize = 1024 * 1024 * 5; // 5MB

  // Check if the file is uploaded
  if (!empty($_FILES['file'])) {
    $file = $_FILES['file'];
    $fileName = $file['name'];
    $fileTmpName = $file['tmp_name'];
    $fileSize = $file['size'];
    $fileType = $file['type'];

    // Check file size
    if ($fileSize > $maxFileSize) {
      echo 'File too large.';
      exit;
    }

    // Check file type
    $allowedTypes = array('image/jpeg', 'image/png', 'application/pdf');
    if (!in_array($fileType, $allowedTypes)) {
      echo 'Invalid file type.';
      exit;
    }

    // Move the file to the upload directory
    $uploadFile = $uploadDir . '/' . $fileName;
    move_uploaded_file($fileTmpName, $uploadFile);

    // Return a success message
    echo 'File uploaded successfully.';
  } else {
    echo 'No file uploaded.';
  }
?>

This script checks the file size and type, and moves the uploaded file to a designated upload directory. Make sure to configure the `$uploadDir` variable to point to a writable directory on your server.

Storing the File in CPanel Storage

Now that we’ve uploaded the file to our server, we need to store it in CPanel storage. We’ll use the CPanel API to interact with the File Manager.

First, we need to obtain an authorization token from the CPanel API:

<?php
  $username = 'your_cpanel_username';
  $password = 'your_cpanel_password';
  $cpanelUrl = 'https://yourdomain.com:2087/api/version/1';

  $authToken = json_decode(file_get_contents($cpanelUrl . '/get_token?api.version=1&username=' . $username . '&password=' . $password), true);

  if ($authToken['result'] == 0) {
    $token = $authToken['token'];
  } else {
    echo 'Failed to obtain authentication token.';
    exit;
  }
?>

Once we have the authorization token, we can use it to upload the file to CPanel storage:

<?php
  $file = 'path/to/uploaded/file.txt';
  $remoteDir = '/public_html/uploaded_files';

  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL, $cpanelUrl . '/execute/Fileman/upload_file');
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_POST, 1);
  curl_setopt($ch, CURLOPT_POSTFIELDS, array(
    'file' => '@' . $file,
    'dir' => $remoteDir,
    'no_overwrite' => 1,
    'token' => $token
  ));

  $response = curl_exec($ch);
  curl_close($ch);

  $uploadResponse = json_decode($response, true);

  if ($uploadResponse['result'] == 1) {
    echo 'File uploaded to CPanel storage successfully.';
  } else {
    echo 'Failed to upload file to CPanel storage.';
  }
?>

In this example, we’re using the `curl` library to send a POST request to the CPanel API, uploading the file to the specified remote directory.

Putting it All Together

Now that we’ve covered the individual components, let’s put it all together. Here’s an updated VueJS component that handles file selection, upload, and storage in CPanel:

<template>
  <input type="file" @change="handleFileChange" multiple>
</template>

<script>
export default {
  methods: {
    handleFileChange(event) {
      const file = event.target.files[0];
      const formData = new FormData();
      formData.append('file', file);

      axios.post('/upload.php', formData, {
        headers: {
          'Content-Type': 'multipart/form-data'
        }
      })
      .then(response => {
        this.uploadFileToCPanel(response.data.file);
      })
      .catch(error => {
        console.error(error);
      });
    },

    uploadFileToCPanel(file) {
      const cpanelUrl = 'https://yourdomain.com:2087/api/version/1';
      const username = 'your_cpanel_username';
      const password = 'your_cpanel_password';

      axios.post(cpanelUrl + '/get_token', {
        api: {
          version: 1
        },
        username: username,
        password: password
      })
      .then(response => {
        const token = response.data.token;

        axios.post(cpanelUrl + '/execute/Fileman/upload_file', {
          file: file,
          dir: '/public_html/uploaded_files',
          no_overwrite: 1,
          token: token
        })
        .then(response => {
          console.log(response.data);
        })
        .catch(error => {
          console.error(error);
        });
      })
      .catch(error => {
        console.error(error);
      });
    }
  }
}
</script>

In this updated component, we’ve added a new method `uploadFileToCPanel` that takes the uploaded file and uses the CPanel API to store it in CPanel storage.
