Form in array doesn't show button after if-statement

Question

I've been looking for hours trying to find a solution. It has to be a simple one, yet, I can't find it. All works well without the if-statement. Each row gets its button. But whenever I put the if-statement back in, the buttons dissappear. What am I doing wrong? Am I overlooking the obvious?

    foreach($result as $row) {

            echo "<tr>
                    <td>".date('d F Y', strtotime($row['DATE']))."</td>
                    <td>".date('H:i  ', strtotime($row['TIME']))."</td>
                    <td>".$row['NAME']."</td>
                    <td>";
                    if ($row['availability'] == 0) { echo "FULL"; } 
                    else if ($row['availability'] != 0) { echo $row['availability']; };
                    "</td>
                    <td> <form method='post' action='res2.php'>
                    <input type='submit' name='action' value='Next'>
                    <input type='hidden' name='ID' value='".$row['ID']."'>
                    </form> </td>
                    </tr>";
        }

You've finished the echo before the if but never restart it, so everything after is just a string, not attached to anything nor output. — Jonnix

In other words, you need another echo after the if/else block. — Barmar

You could also use the ternary operator instead of an if/else statement. — Barmar

General advice: when the else if condition is the opposite of the if condition, you should just use else. — Barmar

You can use the conditional operator to concatenate different strings depending on the availability.

foreach($result as $row) {
    echo "<tr>
              <td>".date('d F Y', strtotime($row['DATE']))."</td>
              <td>".date('H:i  ', strtotime($row['TIME']))."</td>
              <td>".$row['NAME']."</td>
              <td>" . ($row['availability'] == 0 ? "FULL" : $row['availability']) . "</td>
              <td> <form method='post' action='res2.php'>
                   <input type='submit' name='action' value='Next'>
                   <input type='hidden' name='ID' value='".$row['ID']."'>
                   </form> 
              </td>
          </tr>";
}
