Function for deleting row from table using php
Question
Trying to solve my problem with deleting rows from generated table.I have a page called report.php that shows all the rows from database and there is option 'delete row'. My problem is when I click on delete nothing happens and it should go on delete.php file. For now couldnt solve this by myself, maybe you see something that I dont. I dont get any errors so I am a little bit confused. Thank you.

You just need to change this in your $htmltable. (there was an error in appending strings in last block).
$htmltable.= '<tr>
<td>'.$row['prijavljeni_id'].'</td>
<td>'.$row['ime'].' </td>
<td>'.$row['ime_slavljenika'].' </td>
<td>'.$row['datum'] .'</td>
<td>'.$row['poruka'].' </td>
<td>'.$row['vreme'].'</td>
<td><a href="delete.php?prijavljeni_id='.$prijavljeni['prijavljeni_id'].'">Delete</a></td>
</tr>';

Update your code
$result->bindParam(':prijavljeni_id', $prijavljeni_id);
To
$result->bindParam('prijavljeni_id', $prijavljeni_id);
Remember one thing always avoid : before on bindParam method but we using : on prepareQuery to indicate replaceable value.
