My current project involves converting a JSON file to a PDF using mPDF. However, I'm encountering an issue where the JSON table is not being displayed in the HTML after running the PHP code. Instead, only one empty PDF page is generated.
UPDATE: I have made some modifications to the code and now it's almost working correctly. The code successfully creates the table but fails to display all of the JSON Data.
Updated PHP Code
ob_start();
$json = file_get_contents($url);
$json_decoded= json_decode($json);
foreach ($json_decoded as $result) {
$html = '
<!DOCTYPE html>
<html>
<head>
<title>Convert JSON Data to HTML Table</title>
<link href="style.css" rel="stylesheet">
<meta charset="UTF-8">
</head>
<body>
<table>
<tr>
<th>driverno</th>
<th>name</th>
<th>objectno</th>
<th>tagId</th>
<th>lastScanDate</th>
</tr>
<tr>
<td>'.$result->driverno.'</td>
<td>'.$result->name.'</td>
<td>'.$result->objectno.'</td>
<td>'.$result->tagID.'</td>
<td>'.$result->lastScanDate.'</td>
</tr>
<tr>
<td>'.$result->driverno.'</td>
<td>'.$result->name+'</td>
<td>'.$result->objectno+'</td>
<td>'.$result->tagID+'</td>
<td>'.$result->lastScanDate+'</td>
</tr>
</table>
</body>
</html>
';
}
$mpdf->WriteHTML($html);
$mpdf->Output("demo.pdf", 'F');
$mpdf->Output();
?>
JSON Data
{
"driverno":1,
"name":"Aragorn",
"objectno":1,
"tagId":1,
"lastScanDate":"yesterday"
},
{
"driverno":2,
"name":"Legolas",
"objectno":2,
"tagId":2,
"lastScanDate":"today"
},
{
"driverno":3,
"name":"Gimmli",
"objectno":3,
"tagId":3,
"lastScanDate":"today"
},
{
"driverno":4,
"name":"Gandalf",
"objectno":4,
"tagId":4,
"lastScanDate":"today"
}
The issue persists with the last data of the JSON file without displaying the tagID.
