Call a php file from an other php file which has a html form in an echo?

Question

I want to delete mysql rows by clicking on a button in a form. The problem is that I do it in a php while cicyle and the html action attribute does not navigate into the other php page, where the code should delete the row. Here's my code:

 if ($result->num_rows > 0) {
 echo "<table><tr><th>Vezetéknév</th><th>Keresztnév</th><th>Nemzetiség</th>
 <th>Szülőváros</th><th>Találmányok száma</th></tr>";

 while($row = $result->fetch_assoc()) {
     echo "<tr><td>" . $row["vezeteknev"]. "</td><td>" . $row["keresztnev"]. 
  "</td><td>" . $row["nemzetiseg"] ."</td><td>" 
     . $row["szulovaros"]. "</td><td>". $row['talalmanyok']. "
     </td> <td><form action='deleterow.php' method='post'>
     <input type='submit' name='delete' value='".$row['id']."'/>
     </form></td></tr>";       
 }

The other page (deleterow.php):

    header('location:index.php');
    include('DBConnection');

    if(isset($_POST['delete'])){

    $user  = $_POST['delete'];
    $delet_query = mysqli_query($conn,"DELETE FROM feltalalo WHERE id = '$user' ") or die(mysql_error());

 }

Answer 1

Change your code as like below:

while($row = $result->fetch_assoc()) {
     echo "<tr><td>" . $row["vezeteknev"]. "</td><td>" . $row["keresztnev"]. 
  "</td><td>" . $row["nemzetiseg"] ."</td><td>" 
     . $row["szulovaros"]. "</td><td>". $row['talalmanyok']. "
     </td> <td><a href='deleterow.php?delete=".$row['id']."'>Delete</a></td></tr>";       
 }

deleterow.php

if(isset($_GET['delete'])){    
    $user  = $_GET['delete'];
    $delet_query = mysqli_query($conn,"DELETE FROM feltalalo WHERE id = '$user' ") or die(mysql_error());    
}

Answer 2

I believe what you want to achieve is to be able to delete an entry using a link, but have it register as a post request.

To achieve this, you need to generate a form just before your link like so

<form name="item_deleter_{YOUR_ID}" style="display:none;" method="post" action="{URL_FOR_DELETING}">
 <input type="hidden" name="delete" value="{YOUR_ID}">
</form>

Then after this you will create the delete link to have an onclick which submits the above form using javascript like so

<a href="#" onclick="document.item_deleter_{YOUR_ID}.submit(); event.returnValue = false; return false;">Delete</a>
