Call to undefined method HeadlessChromium\Page::sendFile()

[richardsonoge]

I'm trying to send a PDF file as input on a site and I had used this code:

<?php
require 'vendor/autoload.php';

use HeadlessChromium\BrowserFactory;

$browserFactory = new BrowserFactory();
$browser = $browserFactory->createBrowser();

// Open a new page
    $page = $browser->createPage();
    $page->navigate($websiteUrl)->waitForNavigation();

    // Send File in the input file.
    $page->mouse()->find('.ZdLswd', 2)->click();
    $page->sendFile('documents/con.pdf');

But the problem it give me an error, what to do please?

Here's my errors:

richardsonoge@richardsonoge-blooglet:/opt/lampp/htdocs/PdfTranslatorHeadless$ php googletranslate.php
PHP Fatal error:  Uncaught Error: Call to undefined method HeadlessChromium\Page::sendFile() in /opt/lampp/htdocs/PdfTranslatorHeadless/googletranslate.php:32

How can I fix this error?

This method only exists in the Node element. The mouse class doesn't return a node after clicking, this class only controls the real mouse just like a human would. To use the sendFiles method you will need to use the Dom class.

Is this the way I should use it?

<?php
require 'vendor/autoload.php';

use HeadlessChromium\BrowserFactory;
use HeadlessChromium\Dom;

$browserFactory = new BrowserFactory();
$browser = $browserFactory->createBrowser();

// Open a new page
    $page = $browser->createPage();
    $page->navigate($websiteUrl)->waitForNavigation();

    // Send File in the input file.
    $page->mouse()->find('.ZdLswd', 2)->click();
    $page->sendFile('documents/con.pdf');

It gave the same error:

richardsonoge@richardsonoge-blooglet:/opt/lampp/htdocs/PdfTranslatorHeadless$ php googletranslate.php

What do i do? Tell me more please....

Adding the Dom namespace to your code won't do anything, you are still using the mouse class instead of the dom class. There are examples on how to use this class in the readme: https://github.com/chrome-php/chrome?tab=readme-ov-file#interacting-with-dom

I just did it and it keeps giving me another error.

Here's my code:

<?php
require 'vendor/autoload.php';

use HeadlessChromium\BrowserFactory;

$browserFactory = new BrowserFactory();
$browser = $browserFactory->createBrowser();

// Open a new page
    $page = $browser->createPage();
    $page->navigate($websiteUrl)->waitForNavigation();

    // Send File in the input file.
    $page->mouse()->find('.ZdLswd', 2)->click();
    $page->dom()->sendFile('documents/con.pdf');

Here's my errors:

What do i do to fix them?

[enricodias]

I think you lack the basic knowledge about programming in general to accomplish this.

You are still using the mouse class here:

$page->mouse()->find('.ZdLswd', 2)->click();

And when you try to use the dom, there is no node selected. You need to understand how the classes work. Trying random things like that won't work, you'll find another error each time. All the errors you sent here are not related to this lib, they are normal php errors that a dev should be able to easily understand and troubleshot.

I understand you are a beginner, but you probably picked up a project that is too complex for your capabilities. If you are struggling with simple things like this, soon you'll find issues way harder to solve. The css class .ZdLswd that you are trying to select for example, it's a name generated dynamically that will probably change. Google translate has probably a ton of protections to prevent automated softwares like the one you are trying to create, they have a translation api for that and it's a paid product.

This result works fine. I've corrected it, but when the file is uploaded to Google Translate, it doesn't display its size like Google Translate. It only displays “con.pdf 0 Byte”, whereas if I do it myself in Google Translate it displays “con.pdf 431.1Kb”. What can I do? Here's my code:

<?php
require 'vendor/autoload.php';

use HeadlessChromium\BrowserFactory;

$browserFactory = new BrowserFactory();
$browser = $browserFactory->createBrowser();

// Open a new page
    $page = $browser->createPage();
    $page->navigate($websiteUrl)->waitForNavigation();

   // Set the path to your PDF file
    $filePath = 'documents/con.pdf';  // Update this path

    // Send File in the input file of Google Translate.
    $elem = $page->dom()->querySelector('input[type="file"]');
    $elem->sendFile($filePath);
