Nejprve byste měli zavřít všechny vaše <tr>
a <td>
značky. Za druhé, s formulářem neposíláte žádný soubor, a proto dostáváte tento Undefined index: file
chyba, takže tyto řádky odstraňte,
$file_filename=$_FILES['file']['name'];
$target_path = "Newfolder1";
$image_path = $target_path . DIRECTORY_SEPARATOR . "filename";
$image_format = strtolower(pathinfo('filename', PATHINFO_EXTENSION));
Takže poté, co uživatel klikne na view
, měli byste zpracovat svůj formulář a zobrazit obrázek takto,
// your code
if (isset($_POST['View']) ){
$pdf=new fpdf();
$pdf->ADDPage();
$pdf->setfont('Arial','B', 16);
$pdf->Cell(40,10, 'sname',1,0,'c');
$pdf->Cell(40,10, 'sadd',1,0,'c');
$pdf->Cell(40,10, 'category',1,0,'c');
$pdf->Cell(40,10, 'scode',1,0,'c');
$con = mysqli_connect("localhost","root","","school");
if (mysqli_connect_errno()){
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$sql="SELECT * FROM imagetable WHERE ID= '$_POST[search]'";
$result = mysqli_query($con, $sql);
if(!mysqli_query($con, $sql)){
die( "Could not execute sql: $sql");
}
$row = mysqli_fetch_array($result);
$image_path = $row['file'] . DIRECTORY_SEPARATOR . $row['filename']; // path should be like this, process/upload/8/cdv_photo_001.jpg
$image_format = strtolower(pathinfo($image_path, PATHINFO_EXTENSION));
$pdf->Cell(40,10, $row['sname'],1,0,'c');
$pdf->Cell(40,10, $row['sadd'],1,0,'c');
$pdf->Cell(40,10, $row['category'],1,0,'c');
$pdf->Image($image_path,50,100,50,20,$image_format);
$pdf->ln();
$pdf->output();
}
// your code
