Add disabled attribute of button based on rowCount

<button type="button" name="forform" onclick="" class="hit" 
       <?php echo ($rowcount1 > 0) ? '' : 'disabled'; ?>>hit</button>

much better then mine – urfusion Feb 25 '17 at 07:45
it can still continue because i have a js script on my button class 'hit' maybe the js function is overriding it? how can i do it? – Mistaken Identity Feb 25 '17 at 07:49
if button is disabled then on click script will not execute – Naincy Feb 25 '17 at 07:51
my button has a class hit. my hit function in js have a location.href – Mistaken Identity Feb 25 '17 at 07:52

You can do that by put button in if else condition with disable attributes

if ($rowcount1 > 0) {
    ?>
    <h3 class="text-muted"><u>DEPARTURE</u></h3>
    <h4><?php echo "$origin to $destination " ?></h4>
    <table class="table table-hover">
        <thead>
            <tr>
                <th>FLIGHT NO.</th>
                <th>DEPART</th>
                <th>ARRIVE</th>
                <th>AIRPORT</th>
                <th>DURATION</th>
                <th>FLY ONLY</th>
                <th>FLY + BAGGAGE</th>
            </tr>
        </thead>
        <tbody>
    <?php
    foreach ($query as $flightr) {
        echo "<tr>";
        echo "<td>" . $flightr['id'] . "</td>";
        echo "<td>" . $flightr['depart'] . "</td>";
        echo "<td>" . $flightr['arrive'] . "</td>";
        echo "<td>" . $flightr['airport'] . "</td>";
        echo "<td>" . $flightr['duration'] . "</td>";
        echo "<td> <label for=lbl7> <input type='radio' checked id='lbl7' name='flight[]' value='" . $flightr['flyonly'] . "'> PHP " . number_format($flightr['flyonly']) . "</label></td>";
        echo "<td> <label for=lbl8> <input type='radio' checked id='lbl8' name='flight[]' value='" . $flightr['flybaggage'] . "'> PHP " . number_format($flightr['flybaggage']) . "</label></td>";
        echo "</tr>";
    }
    ?>
        </tbody>
    </table>
    <hr>
    <button type="button" name="forform" onclick="" class="hit">hit</button>
    <?php
} else {
    echo " <div class='alert alert-info' role='alert'>
                                       No results found on <BIG class='text-muted'>Departure</BIG> pick another flight thank you.
                                    </div>
                            ";
    echo '<button type="button" name="forform" onclick="" class="hit" disable="disable">hit</button>';
}
?>
