Welcome folks today in this blog post we will be adding multiple images inside pdf document using multiple form input fields in php. All the full source code of the application is shown below.
Get Started
In order to get started you need to make an index.php file and copy paste the following code
index.php
|
1 2 3 4 5 6 7 8 9 10 11 12 |
<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>" enctype="multipart/form-data"> <label for="image1">Image 1:</label> <input type="file" name="image1" id="image1"> <br> <label for="image2">Image 2:</label> <input type="file" name="image2" id="image2"> <br> <label for="image3">Image 3:</label> <input type="file" name="image3" id="image3"> <br> <input type="submit" value="Generate PDF"> </form> |
As you can see we have a simple user html5 form where we have multiple input fields where we allow the users to select multiple image files. And then we have the simple submit button to add the images inside the pdf document.
And now we need to copy paste the below php code to add the images inside the pdf document using the tcpdf library.
Installing TCPDF Library Using Composer
Now guys first of all create the composer.json file and copy paste the following code to it
composer.json
|
1 2 3 4 5 |
{ "require": { "tecnickcom/tcpdf": "^6.2.13" } } |
And now you need to execute the below command to install the dependencies from composer as shown below
composer update
After executing this command this will create the vendor folder inside the root directory and it will contain all the libraries of tcpdf as shown below
index.php
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 |
<?php // Check if the form has been submitted if ($_SERVER['REQUEST_METHOD'] == 'POST') { // Include the TCPDF library require_once('./vendor/autoload.php'); // Create a new PDF document $pdf = new TCPDF(); // Set the document title $pdf->SetTitle('My PDF Document'); // Set the font $pdf->SetFont('helvetica', '', 12); // Loop through the uploaded images foreach ($_FILES as $file) { // Check if the file is an image if ($file['type'] == 'image/jpeg' || $file['type'] == 'image/png') { // Add the image to the PDF document $pdf->AddPage(); $pdf->Image($file['tmp_name'], 0, 0, 0, 0, '', '', '', true, 900, '', false, false, 1, false, false, false); } } // Output the PDF document $pdf->Output('my_pdf_document.pdf', 'I'); } ?> |
As you can see we are importing the autoload.php file of the tcpdf library which is stored inside the vendor folder and then we are checking if the submit button is clicked by the user of the form. And then we are getting the temporary path of the image file without uploading it we are getting the temp path using the $_FILES[] array and then we are adding new page in pdf document using AddPage() method of TCPDF library and then we are using the Image() method of tcpdf library to add the image we are passing three arguments. Now we are repeating the same process for all the images selected by the user using the foreach loop. First is the path of the image and then we are passing the x and y coordinates. And lastly we are showing the output of the pdf document inside the browser as an attachment using the Output() method.
