Attach image in a php form and use html2pdf - php

Question

i have a php form and use html2pdf (TCPDF). The php form works when I use text and images that already include in the form, but now I want to attach a image and also include that in the pdf file.
The code I am using now I get the filename.
To attach the image I am using
$<span><input type="file" name="foto"></span>
And to include it in the pdf-file I use this code
$foto = $_POST['foto'];
$content .= '<img src='.$foto.'with=200 height=auto>';
Sorry for my bad English!

Answer 1

Do an normal HTML file upload like this:
<form method="post" enctype="multipart/form-data">
<label>Deine Datei ;) :
<input name="fileUpload" type="file" accept="image/*">
</label>
<label>Your Name:
<input name="userName" type="text" accept="image/*">
</label>
<button type="submite" name="submite">Upload</button>
</form>
And on the PHP side you must move your file:
if(isset($_POST["submit"])) {
$userName = $_POST['userName']; // the normale methode
$check = getimagesize($_FILES["fileUpload"]["tmp_name"]);
if($check !== false) {
$temp_path_to_file = $_FILES['fileUpload']['tmp_name'];
$file_content = file_get_contents($temp_path_to_file);
// and now past your image to your PDF.
// if you want to save the image on the server you must move it with this (its not necessary if you want only to past it in your PDF)
if(move_uploaded_file($temp_path_to_file, '/my/image/folder/image_'.uniqid() . '.' . pathinfo($filename, PATHINFO_EXTENSION);
}
}
EDIT:
For your example you must convert the $file_content to an base64 string. Than you can past it in your image:
$base64 = 'data:image/' . pathinfo($filename, PATHINFO_EXTENSION) . ';base64,' . base64_encode($file_content);
echo '<img src="'. $base64 .'" style="with: 200; height: auto">';
